Case Study No. 2

 

Index

 

Introduction

 

This is the second article in my Case Study series about how to successfully patent software in Europe.

 

If not done so already, please read my first article in this series, in which I analyse a first European software patent by Apple Inc, and dissect how this was granted.

 

As introduced in my first article, it is a common misconception that you cannot obtain a patent in Europe for software.

 

Since I am frequently asked about the perceived difficulties of software patenting in Europe, I thought a Case Study series looking at Apple Inc and their patent portfolio would be interesting. Apple receives hundreds of successfully granted European patents each year, with a large percentage being software or software-related patents.

 

This second article about successfully patenting software looks at how to protect an improvement to the graphical user interface of an Apple iPhone® or other Apple device to control its integrated cameras.

 

The second Apple patent that we will now examine is EP3483653B1.

 

Originally filed in May 2017, this patent granted quite rapidly (for a European patent) in October 2020.

 

How To Find Software Patents

 

How to search for software patents was covered briefly in my first article, and you can see on the front page of this patent EP’653 some similar classification codes. If you are interested in looking up more software-related patents, start with these:

 

Software

 

Background Of The Patent

 

This patent application originally had 284 claims!

 

Considering large excess claims fees are incurred for claim numbers in excess of the first fifteen claims, and then this increases again beyond the fiftieth claim, it is not surprising that Apple decided to ultimately trim the claims back to fifteen.

 

How Does Apple Obtain So Many Granted Software Patents in Europe?

 

Apple uses a similar and simple strategy in most cases:

 

  1. Start with a ‘method’ claim, and then
  2. Wrap up the claim set with a ‘computer-readable storage medium’ claim and an ‘electronic device’ claim at the end.

 

Why start with a ‘method’ claim?

 

Under European patent law, software as such is excluded from patentability. Therefore, we need to be smart about the wording. If we simply use language which relates to or states ‘software’, then we are not going to get anywhere fast.

 

Software is, by-and-large, the processing or movement of data to enable actions to be performed. Therefore, breaking down the action of the software into a process or ‘methodology’ allows the functional characteristics to be worded in a way that allows patent protection to be granted.

 

Dissecting The Claims

 

Let’s take a look at the ‘method’ claim, the ‘computer-readable storage medium’ claim, and the ‘electronic device’ claim forming claims 1, 14 and 15 of this patent EP’653.

 

  1. Remember, when reading the following ‘method’ claim, this is explaining the interaction between the screen of the iPhone® , the iPhone’s camera(s), and the processing (in other words, data movement and therefore the software) between the two.

 

  1. Also be aware that the term used in this ‘method’ claim – ‘affordance’ means an object, such as a button or slider, which is designed to show the user the action which can be taken without having to consider how it should be used.

 

So, in this case, the ‘magnification adjustment affordance’ is, for example, a button or slider that appears on your phone’s screen, and it is designed that you immediately know that if you turn it or slide it, the camera’s magnification or zoom will be adjusted.

 

Method Claim 1

 

NB: My comments are in italicized parentheses to help you understand the wording of the claim.

‘A method, comprising:

 

at an electronic device [ed: in other words, your iPhone®] with one or more cameras, one or more input devices [ed: some sensors], and a display [ed: your iPhone’s screen]:

 

concurrently displaying, on the display:

 

a digital viewfinder [ed: so, you’re shown on the screen what the camera is seeing] for capturing media with the one or more cameras at a first magnification level [ed: for example, the viewfinder is in a none zoomed state]; and

 

a magnification adjustment affordance [ed: in other words, a software dial on the user screen that lets you zoom or not];

 

while concurrently displaying the digital viewfinder and the magnification adjustment affordance [ed: so, showing both the viewfinder and the zoom adjuster together on the screen], detecting, via the one or more input devices, a first gesture [ed: sensors in the phone detect your interaction with the screen] at a location corresponding to the magnification adjustment affordance,

 

wherein the one or more input devices are configured to detect a first type of gesture and a second type of gesture that is different from the first type of gesture [ed: in other words, your iPhone® has sensors and associated software that can differentiate between two different finger movements on your phone’s screen];

 

in response to detecting the first gesture at the location corresponding to the magnification adjustment affordance [ed: so, you move your finger on the screen of your phone in a first direction to adjust the zoom]:

 

in accordance with a determination that the first gesture is of the second type:

 

preparing to capture media with the one or more cameras at a dynamically-selected magnification level [ed: so, this implies that software within the phone makes on-the-fly assumptions to assist in the capturing of the video or image] different from the first magnification level, wherein the dynamically-selected magnification level is selected based on a magnitude of the first gesture [ed: in other words, your iPhone® interprets the size of your finger scroll, and adjusts the zoom level accordingly]; and

 

displaying, on the display, a zoom control at the location corresponding to the first gesture [ed: now the software in the iPhone® pops up a specific digital zoom control on your screen at your finger location]; and

 

in accordance with a determination that the first gesture is of the first type preparing to capture media with the one or more cameras at a second magnification level different from the first magnification level without displaying the zoom control [ed: and finally, the software determines with this different finger gesture that you don’t need the specific zoom control displayed].’

 

So, the general gist of this ‘software’ method claim is to cover a process which, in reality uses software code, shows a viewfinder for a camera on your phone’s screen, along with a zoom option. It detects your finger touching the screen, and interprets that touch either to bring up a specific zoom control before taking the picture, or simply to take the picture.

 

Computer-Readable Storage Medium Claim 14

 

Now, let’s look at claim 14, which reminds us that method claim 1 is primarily a software claim written to outline the processing steps of the backend architecture interconnecting the screen of the iPhone® and the camera(s).

 

Again, my comments are in italicized parentheses to help you understand the wording of the claim :-

 

‘A computer-readable storage medium [ed: in other words, some memory] storing one or more programs [ed: software!] configured to be executed by one or more processors of an electronic device [ed: for example, your iPhone®] with one or more cameras, one or more input devices, and a display, the one or more programs including instructions [ed: code] for performing any of the methods of claims 1-13 [ed: method claim 1 above is the broadest claim, so this is the one of most interest here].’

 

Electronic Device Claim 15

 

And, just in case we forget that our method claim 1 above needs to be implemented on an actual Apple product, we round off our software claim set with claim 15, which recites:

 

‘An electronic device [ed: for example, your iPhone® again], comprising:

 

one or more cameras;

 

one or more input devices [ed: in other words, your touchscreen];

 

a display;

 

one or more processors; and

 

a memory storing one or more programs [ed: in other words, software!] configured to be executed by the one or more processors, the one or more programs including instructions [ed: code] for performing any of the methods of claims 1-13 [ed: again, just focus on method claim 1 discussed above].’

 

What Happened During Examination?

 

How did these claims stack up before the European Examiner? Surprisingly well.

 

The European Examiner raised some initial novelty (uniqueness) and inventive step (obviousness) objections, based on a few prior patent documents. One set of counter-arguments was made.

 

Part of Apple’s counter to the Examiner’s objection of a lack of inventiveness was to state their ‘objective technical problem’ that the development was seeking to solve. This is not unusual in European patent prosecution. But, interestingly in this case, was how basic their statement was:

 

Case

 

Somewhat surprisingly, the Examiner rapidly backed down.

 

A side-note to mention is therefore to make good use of the ‘Statements of Invention’ in the patent document when it is being originally drafted.

 

The Statements of Invention typically restate the language of the claims near the beginning of the patent document. However, use this as an opportunity to thoroughly explain the technical benefits of the features of the claims, what technical problems are overcome, and what results are achieved. This potentially gives you improved support when stating your ‘objective technical problem’ during examination to overcome an inventive step objection.

 

A second note is that the European Examiner made no comment or objection to the fact that the claim set essentially defines the implementation of software. Written in the form of a method claim outlining processing and the interaction of, largely physical sounding, components is the trick to being successful.

 

This European software patent covering a user interface for the phone’s camera(s) was therefore granted in short order.

 

Conclusion

 

In addition to the ‘Summary’ at the end of my first Case Study article, we can add these closing thoughts when considering how to successfully patent software in Europe:

 

  • Look at all the figures used in this Apple software patent EP’653. These really do backup the processing steps that are taking place, the backend architecture, and a gives the impression of good sufficiency and enabling disclosure. The patent examiners will like this technical support;
  • Plenty of ‘hardware’ type technical language is used in the claims to explain the interaction between the display, the cameras, and the processing steps therebetween. This makes it much harder for an examiner to argue that the ‘inventiveness’ of the claim only relates to excluded software matter. Again, this makes it easier to obtain grant of a software-type patent in Europe; and
  • Make use of the Statements of Invention to outline possible ‘objective technical problems’ and solutions right at the outset when preparing the patent document for initial filing.

The Effect of The Coronavirus on Official Deadlines (Updated)

by

Deadlines

 

Normally, having to face moving goalposts would be a bad thing, but it is proving to be beneficial when it comes to IP deadlines falling during the Covid-19 pandemic.

 

For now, deadlines before the UK Intellectual Property Office remain extended under the ‘interrupted days’ provision, although this will be reviewed on 7th May. The UK IPO still intends to give at least 2 weeks’ notice before the automatic extension is halted.

 

Most deadlines before the European Patent Office have also been extended again to 2nd June, and deadlines before the EU Intellectual Property Office (for designs & trade marks) have been further extended to 18th May.

 

Further extensions may yet be available, depending on how quickly the pandemic is brought under control.

 

If you have a particular case you are concerned about, please feel free to get in touch and we can confirm the deadline to put your mind at ease

Greater Protection in the UK For Patent Owners

by

UK Patent Owners

 

A quick summary of two relatively recent court decisions in the UK explaining why having a British granted patent now gives you generally greater protection under the newly adopted ‘doctrine of equivalents’ without the limitation of ‘file history estoppel’.

 

At the end and in view of the above, this article also gives some suggestions to consider when you are now writing a new patent (or having a new patent written for you).

 

Recent Decision 1:

 

Excel-Eucan Limited v Source Vagabond Systems Limited

 

The patent relates to a ‘link-tail’ bag for feeding ammunition to a machine gun:

 

 

The single granted independent claim reads:

 

 

Shown below(1) are the Link-Tail (top example, and subject of the above claim 1), and the 2017 Bag (lower example, and competitor product); in both cases with the top flap open at the right hand end:

 

 

The important bit to notice is that the competitor bag (the ‘2017 Bag’) at the bottom does not have a zipped opening (you can see the zipped opening in the patented ‘Link-Tail’ bag at the top and circled) or indeed any openable closure along its length. If you re-read the claim above, you can see that the ‘openable closure’ is a required feature of the granted claim.

 

The judge concluded: ‘I am satisfied that the 2017 Bag (ed: competitor product) achieves the same result in substantially the same way as the invention. Both bags can be loaded horizontally and/or vertically and substantially the same result is achieved. In neither case is the openable closure necessary.’ Highlights added.

 

Granted claim 1 clearly requires ‘an openable closure extending substantially from the first end to the second end’. The court held that this feature is immaterial to the ‘inventive concept’.

 

Therefore, infringement was found.

 

This is a positive outcome for the patent owner. A product without all of the features of their granted claim 1 was still held to infringe.

 

Recent Decision 2:

 

Icescape Limited v Ice-World International Bv & Ors

 

Ice-World’s patent is for cooling a mobile ice rink.

 

To make transport easier, the cooling system of manifolds feeding cooling pipes can be folded up.

 

The diagram below(2) from Ice-World’s patent shows two ‘elements’ or sections of the Ice-World design (41, 42, each highlighted by a green box). Each section (41, 42) has a main feed pipe or manifold (43, 45, circled in purple) and a discharge manifold (44, 46, also circled in purple).

 

The feed and discharge manifolds of the two sections (41, 42) are connected to each other via joints 47 and 48 (circled in red) respectively.

 

As such, the cooling fluid entering the feed manifold (45) of the second section (42) must pass through the feed manifold (43) of the first section (41). The same applies to the discharge manifolds (44, 46), albeit in a reverse direction of flow.

 

In other words, the ections (41, 42) are considered to be connected in series or one after the other.

 

Each section (41, 42) also has a number of longitudinal cooling pipes (50, 51, circled in blue) which have a ‘first series’ or bank of pipe sections (68, 68’, 68’’) connected in series with a ‘second series’ or bank of pipe sections (69, 69’, 69’’) by flexible joint members 70 (circled green). The result of the above is that this jointing (70) of the various pipes (50, 51) allows folding of the system to permit easier transport for mobile ice-rink applications.

 

Scheme 1

 

The variant by Ice-World’s competitor, Icescape, is diagrammatically shown below(2). The arrangement has three ‘elements’ or sections (E1, E2, E3, highlighted as green boxes).

 

Each section of the competitor’s system has a feed manifold (F3, circled in purple), a discharge manifold (D3, circled in purple) and cooling pipes  ‘C’ (circled in blue) extending in parallel with each other.

 

The cooling pipes ‘C’ comprised foldable joints, which are not visible in the diagram below.

 

However, Icescape believed that they would circumvent the Ice-World patent if they positioned their sections (E1, E2 and E3) such that the fluid entering the feed manifold (F3, circled in purple) of any of the three sections (E1, E2, E3) did not pass through the feed manifold of any other of the three sections (E1, E2, E3).

 

In other words, the sections (E1, E2, E3) are in parallel, rather than in series.

 

As such, in the Icescape arrangement, there is no equivalent to the joints (47 and 48) in the Ice-World patent.

 

Icescape believed that this separated them sufficiently from the Ice-World patent:

 

Scheme 2

 

Granted claim 1 of the Ice-World patent was set out in integer form (i.e. as a list) by the judge(2):

 

“Cooling member (21, 40) for a mobile ice rink provided with:

 

a feed manifold (43, 45) extending in a transverse direction and a discharge manifold (44, 46), and a number of longitudinal pipes (50, 51) which extend transversely to the manifolds and can be connected at a first end (53, 54) to a manifold (43, 44, 45, 46), two longitudinal pipes (50, 51) in each case being in fluid communication with one another at a second end (60, 61) via a connector (27, 63), so that a fluid path is formed from the feed manifold (43, 45) to the discharge manifold (44, 46) via the two connected longitudinal pipes (50, 51), characterised in that

 

  1. the cooling member comprises at least two elements (41, 42), each with a feed manifold (43, 45) and discharge manifold (44, 46) and a number of longitudinal pipes (50, 51) connected thereto,
  2. wherein each longitudinal pipe comprises at least two rigid pipe sections (3, 12, 16, 24, 68, 69) that are connected to one another via a joint member (4, 13, 17, 25, 70, 132, 133) such that they are fluid-tight, and
  3. wherein by moving the joint members (4, 13, 17, 25, 70, 132, 133) a first series of parallel pipe sections (68, 68′, 68″) can be placed in a transport position with respect to a second series of parallel pipe sections (69, 69′, 69″) connected thereto, in which transport position the two series of pipe sections (68, 68′, 68″; 69, 69′, 69″) are at an angle with respect to one another or are positioned on top of one another, and can be placed in an operational position in which the two series of pipe sections (68, 68′, 68″; 69, 69′, 69″) extend in the extension of one another,
  4. wherein the first and the second element (41, 42) can be placed in the operational position alongside one another such that the feed and discharge manifolds (43, 44, 45, 46) of the elements extend in the extension of one another in the transverse direction,
  5. wherein the feed and discharge manifolds of the two elements are provided with a coupling member (47, 48) to make a fluid-tight connection between the respective feed and discharge manifolds of the first and the second element.”

 

It was submitted that ‘the key novel and inventive feature of the invention is integer C […] the use of joint members (70, ed: see first image above) which allow the longitudinal pipes to have two configurations, one in which the cooling pipes are extended and the other in which the cooling pipes are folded back on one another. This is the integer which enables the claimed system to work in its intended manner. Integer C is […] the invention.’

 

The competitor, Icescape, accepted that their design had all of the features of Ice-World’s granted Claim 1 except integers D and E (i.e. they had features A, B and C, but not D and E) due to their parallel arrangement.

 

On Appeal, it was held that, although the claim must be taken literally to be limited to a ‘series’ connection between the adjacent ‘elements’, a ‘parallel’ connection is an alternative way of implementing the same concept. The difference in the positioning of the elements relative to each other has nothing to do with the core inventive contribution of the patent (the foldability of the cooling pipes 50, 51 and C).

 

The judge held that ‘there is nothing to suggest that the patentee regarded series connection as essential in any relevant sense’.

 

The judge also noted that the prosecution history did nothing to alter this view, and as such ‘file history estoppel’ or restricting the scope of the claim based on comments made by the patentee during examination still plays no part in the determination of the inventive concept.

 

However, the judge nuanced this statement by reinforcing a previous judgement that reference to the prosecution history would be appropriate in two scenarios. The first scenario was where “(i) the point at issue is truly unclear if one confines oneself to the specification and claims of the patent, and the contents of the file unambiguously resolve the point”.

 

The second scenario is where “(ii) it would be contrary to the public interest for the contents of the file to be ignored”.

 

The judge illustrated the second scenario as occurring where the patentee had explicitly renounced a variant during prosecution, but later tried to enforce the patent against that very variant.

 

Therefore, on Appeal, the decision was overturned and the patent was held to be infringed (although it was also held invalid due to an invalid priority claim, but that is beyond the scope of this article’s topic).

 

Again, this is another positive for the patent owner. The competitor’s product clearly did not have all the features of the granted claim 1. But, the system was held to achieve substantially the same inventive concept, and as such infringement was found.

 

Comment

 

  • In light of these decisions, it seems to make sense to ‘characterise’ your independent claims at the outset with ‘results to be achieved’ type language that explains the intended inventive concept. Even if the claim language is then limited during prosecution, the broad ‘inventive concept’ (or even concepts) remains stated on filing.
  • Furthermore, including caveats and examples throughout the patent specification would seem to encourage a broad interpretation of the ‘inventive concept’.
  • Having a well-rounded and broad ‘conclusion’ at the end of your description which restates in different language the ‘inventive concept/concepts’ rather than necessarily just specific features also makes sense.
  • It is also worth bearing in mind that, although a claim can be infringed, the patent can still be held invalid in light of prior art. With the broader interpretation being given to granted claims, being aware of such prior art therefore now becomes increasingly more relevant.
  • The alleged infringer will likely still push for ‘file history estoppel’ or in other words using the examination history to mould or shape the scope of the granted main claims and what the inventive concept should be construed as. It is therefore prudent to be mindful of statements being made during examination. Re-stating the broad inventive concept during examination is a good idea, but not necessarily explicitly designating essential features which are deemed to make up that inventive concept.

World IP Day – 26th April – Celebrating Innovation In a Crisis

by

World IP Day

 

The arrival of the Coronavirus onto the world’s stage has brought into sharp focus the need for businesses to combine thinking on their feet with innovation and creativity. As we celebrated World Intellectual Property Day on the 26th April, it is a chance to focus on the role intellectual property (IP) rights play in encouraging innovation and creativity, Albright IP’s managing director Robert Games takes a look at how things might play out for the companies which are willing to ‘think smart’…

 

With the NHS crying out for ventilators, and personal protective equipment such as masks, scrubs and face shields, it’s those companies that can demonstrate agility and manufacturing flexibility that are proving best placed to respond. We’ve seen some great examples of businesses which have recognised the need and taken a creative approach to their design, manufacturing processes and product lines.

 

At one end of the scale, you’ve got companies like Ineos and Dyson switching design and production to hand sanitiser and ventilators respectively. Ineos have committed to building a whole new manufacturing facility in just 10 days with a planned one million bottles of much-needed hand sanitiser due to come off its production lines each day – something that will be replicated in Germany.

 

Leading from the front

 

Dyson is working in partnership with The Technology Partnership (TTP) on a brand-new ventilator design called the CoVent which can be made quickly and at high volumes. Using Dyson’s existing Digital Motor design, as well as the company’s air purification products, the new product will deliver safe and consistent ventilation for COVID-19 patients.

 

Another UK company, Gtech, more familiar with the world of household appliances and vacuum cleaners, has made two ventilator designs available free of charge (www.gtech.co.uk/ventilator) after the government decided it no longer required the company’s assistance.

 

There’s the fantastic partnership between University College London, NHS clinicians and Mercedes Formula 1 which has developed a new breathing aid which can deliver oxygen to the lungs without the need for a ventilator.

 

And there’s the VentilatorChallengeUK consortium which has brought together some big names in the industrial, technology and engineering sectors, including Airbus, BAE Systems, Ford, Rolls Royce and Siemens. They are pooling their creative resources to develop new ventilator technology at speed.

 

At the same time, Innovate UK has been leading from the front and set up a competition to encourage business-led innovation in response to COVID-19. It’s offering a total of up to £20m and the winners are due to be announced on May 1st.

 

It’s encouraging to see so many organisations putting competitiveness to one side and coming together during this unprecedented time. Keeping their innovation and creativity muscles flexed in this way will stand them in good stead once we emerge from the other side of this pandemic.

 

This continued approach to innovation will keep them better placed for whatever the next chapter looks like, as will their employees who will very likely have learned new skills and expertise. But it’s not only the world-renowned brands that are demonstrating their flexibility when it comes to addressing the current challenges being faced in the health service and wider carer sectors

 

Celebrating our local innovation

 

In the South West we have our own business heroes that should be celebrated such as Emma Willis the Gloucestershire fashion house that has turned its hand to producing scrubs for NHS frontline staff; the Charlton Kings school, Balcarras, that’s used its 3D printer to make face shields;

 

And Staverton-based company Safran has joined forces with Decathlon and Segula Technologies to produce face protection masks. The masks are adapted from Decathlon’s Easybreath Subsea snorkelling mask. They’ve also made the adaptation design available via open access to anyone who wants to make the masks using their own 3D printer.

 

Further afield is the Canadian boy scout who deserves an honorary mention! He designed and printed facemask ear guards using ingenuity and his own 3D printer. He’s now shared his creation so anyone with a 3D printer can download and print his design.

 

Keep the innovation going

 

This approach to innovation and creativity perfectly sums up what World IP day stands for and showcases the potential within all businesses to innovate when they put their mind to it. There’s a humbling generosity of focus at the moment on sharing ideas, designs, equipment and know-how, and this is absolutely how it should be if we’re going to ensure the health service, the care sector and more besides have the right tools and equipment to enable them to do their jobs as safely as possible.

 

While it’s quite right for companies to be putting collaboration first in the current climate, it’s also important for companies who want to stay ahead of the competition and grow their businesses to look after their intellectual property.

 

When we final emerge from this unprecedented chapter in our shared lives, I would encourage businesses to look back at what they’ve learned, capture any innovative ideas or processes that will help them in the future, and continue to encourage creativity among their workforces.

 

Can a Deity Apply For a British Patent?

by

British Patent

 

In this series of three articles, we explore common and slightly less common questions regarding Applying for and Owning a British or European Patent.

 

Who can apply for a patent?

 

Under UK law, anyone can apply for a patent, whether by themselves or jointly with another person. In this context, a “person” is understood to be a natural person (i.e. an individual) or a corporate body, limited companies being the most common type of the latter. Other corporate bodies include foreign states, universities and limited liability partnerships (LLP) in the UK, to name a few.

 

An unincorporate partnership on the other hand, such as a limited partnership, is excluded from applying for a patent. In this case, one or more of the personally responsible partners would need to apply instead.

 

The UK Intellectual Property Office (UKIPO) will also accept as applicant some foreign corporate entities not recognised as such in the UK, an extensive but non-exhaustive list of which can be found here.

 

If not listed above, other foreign entities which are not considered corporate bodies in the UK but which, under the laws of a foreign state can own land and property in their own name may potentially be considered as applicants for a British patent. For instance, Hindu law in India recognises a Hindu idol as both a deity and a “juridical subject being capable in law of holding property”.  Therefore, whilst this scenario remains to be tested, a Hindu idol may, in theory, apply for and own a British patent (a form of property). In practice, the representatives of the applicant would need to confirm to the UKIPO that the Hindu idol can own property.

 

Similar provisions exist under European law. A European patent application may be filed by “any natural or legal person, or any body equivalent to a legal person by virtue of the law governing it” (Article 58 EPC).

 

What is a proper chain of entitlement and why is it important?

 

Applying for a patent is only the first hurdle in the lengthy process of obtaining patent protection. Whilst anyone can apply for a patent, a patent will only be granted to an entitled person or persons (assuming the invention is patentable). If a patent is granted (incorrectly) to a non-entitled person, the patent may be transferred to the entitled party and/or may be revoked. Hence it is important to have a clear trail or chain of entitlement in place, i.e. why and how the applicant is the entitled party, particularly if the applicant is not the inventor.

 

By default in the UK and in Europe, the entitled person is the inventor. The inventor is defined as the person who devises or creates the invention. An inventor can only be an individual, not a corporate entity nor an Artificial Intelligence (AI) as clarified under UK law (see section 3.05). The European Patent Office has adopted a similar stance, as shown in two recent European patent applications.

 

However, another party may be entitled to the patent in preference to the inventor if a law or agreement to that effect was in place at the time of invention. Such a party is the successor in title to the inventor. An agreement may include an assignment or a contract, for example. The right to a patent can be further transferred by the entitled party to yet another party, via similar means.

 

In summary, it is always advisable to ensure that there is a proper chain of entitlement in place, as the absence of one can result in a transfer or the revocation of a patent.

 

Does an employer automatically own the right to a patent for an invention created by an employee?

 

An example of a law in the previous paragraph pertains to employer-employee cases.

 

Under UK law, the employer is entitled to the right to a patent if:

 

1/ the employee made the invention during the course of their normal duties or specially assigned duties, or if the employee has a special obligation to further the interests of the company (such as by being a director of the company), and

 

2/ it could be expected that an invention may arise from carrying out these duties.

 

If any of these conditions is not fulfilled, the right belongs to the employee instead, unless there is any agreement to the contrary.

 

For example, a researcher employed by a university is expected to do research as part of her normal duties. It can be expected that an invention may arise from such research. In this case, the invention and the right to a patent protecting the invention would likely belong to her employer.

 

On the other hand, the normal cleaning duties of a cleaner employed by the same institute would not be expected to give rise to an invention. As such, if the cleaner creates an invention, the right to the patent would vest with him, rather than the employer.

 

In essence, the employer typically owns the right to a patent in most cases, but it may be worth clarifying the ownership of any IP in a contract of employment.

 

What happens to a patent after the owner ceases to be?

 

In the case of a natural owner, the patent passes to their estate. Usually, the patent rights are transferred to a new owner, typically according to the deceased owner’s will if one was made, or according to the rules of intestacy in the absence of a will. This also applies to any patent applications. In this case, it is advisable to prepare a will so that the estate is administered according to the deceased person’s last wishes. As the value of IP is included in the estate for the purposes of calculating inheritance tax, it may also be worth consulting an Inheritance Lawyer specialised in IP law.

 

In the case of a corporate owner which goes into administration, an administrator is appointed. The administrator administers the assets which may involve attempting to sell the patent to cover any debts. If no new owner can be found, upon dissolution of the company, the patent will pass to the Crown. The same applies to patent applications. In this case, assigning the patent or patent application prior to entering administration may be worth considering to avoid losing the patent or application to another party or to the Crown.

The Effect of the Coronavirus on Official Deadlines

by

Intellectual Property Covid-19

 

National and regional intellectual property offices are, like all of us, feeling the effects of the on-going Covid-19 outbreak. Some of them have now extended deadlines or put into place corresponding measures which are aimed at helping you to weather the storm without losing your rights.

 

We remain very much open for business as usual, but here is a brief overview of the positions being adopted by the UK Intellectual Property Office (UK IPO), the European Patent Office (EPO), the EU Intellectual Property Office (EUIPO), and the World Intellectual Property Organization (WIPO).

 

UK IPO

 

The UK IPO has announced that all deadlines for UK patents, designs, trademarks, supplementary protection certificates, and applications for any of those rights, have been indefinitely extended. This applies to deadlines from 24th March 2020 to an unspecified future date.

 

It is important to note that this extension applies to UK rights only. Any applications for overseas rights made under international or regional agreements must still be made by the relevant deadlines.

 

The situation will be reviewed on 17th April 2020. The UK IPO indicates that there will be a two-week notice period before the extension period ends, so the earliest that any extended deadlines may fall would be 1st May 2020.

 

EPO

 

The EPO has announced that deadlines for time limits expiring on or after 15th March 2020 are extended until at least 17th April 2020. Oral proceedings scheduled during the same period have been suspended until further notice, unless video-conferencing has already been arranged.

 

It should be noted that the extensions apply to parties which are already party to proceedings under the European Patent Convention (EPC) or Patent Co-operation Treaty (PCT).

 

For opposition filing deadlines, it should be noted that the EPO has stated that the current situation qualifies as a ‘general dislocation’ under rule 134(2) EPC. Therefore, this should also extend the deadline for filing an opposition to a European patent until at least 17th April 2020, assuming that the opposition deadline had not already expired prior to 15th March 2020.

 

The EPO has also pointed out that the extension does not apply to some things such as the deadline for filing a divisional application and the deadline for making written submissions before oral proceedings. The same notice indicates that renewal fees falling due on 31st March 2020 can be paid until 17th April 2020, and that such renewal fees can for now be paid at the current rate rather than the increased rates coming into force from 1st April 2020.

 

EUIPO

 

The EUIPO has announced that deadlines expiring between 9th March 2020 and 30th April 2020 have been extended to 1st May 2020 (in practice, 4th May 2020, since 1st May is a public holiday followed by a weekend).

 

This specifically relates to deadlines for trademark or design matters, but does not cover deadlines which relate to other matters or which relate to another authority, e.g. bringing an action before the General Court against a Board of Appeal decision.

 

WIPO

 

The WIPO is still processing international patent, design and trademark applications as normal. The latest newsletter contains some advice on possible remedies in the event that a PCT deadline is missed for an international patent application.

 

If you are nearing the end of a priority filing period (12 months from first filing a patent application, or 6 months from first filing a design or trademark application), then the Paris Convention only allows for an extension to the priority period where the national Office was closed to the filing of applications. Please click the relevant links here for further details relating to the PCT, Hague System and Madrid System procedures as affected by the Covid-19 situation.

 

For the time being, the UK IPO, EPO, EUIPO and WIPO are still accepting applications. The EPO and EUIPO have indicated that priority filing deadlines may be extended, for now. However, to be on the safe side, if you plan to file a national/regional application, a PCT international patent application, a Hague System international design application, or a Madrid System international trademark application through one of those Offices, it is still worth aiming to file subsequent applications by the priority deadline.

 

The situation for all of the above Offices is still evolving, but we will endeavour to continue to provide up-to-date information on our website. If you have a query relating to a specific case, please do not hesitate to contact us for further information.

The Invention of Rules

by

 

BBC

 

Intellectual Property can be a difficult topic to publicize, so credit is due to the BBC for continuing to keep the fundamentals of the patent system in the public (Dragon’s) eye year after year. Auntie Beeb’s mission statement is to inform, educate and entertain, and for such a weighty topic, you would expect the home of respected heavyweights such as Attenborough, Bragg, and O’Carroll to be firmly in favour of educating the public and bringing the subject to the attention of younger consumers.

 

Bitesize

 

BBC Bitesize is an online study support platform for school-age students in the UK, and contains lots of articles that delve into interesting titbits from the news. I, as a mostly grown man, therefore was naturally drawn to a blog post entitled ‘How do you invent a new sport?’. The article itself is a brief discussion of the history of Bossaball, a mix of football, volleyball and extreme gymnastics.

 

Unfortunately, the blog has a rather fuzzy approach to the fundamentals of IP, which will no doubt encourage the reader towards some of the more common misconceptions about the difference between patent, trademark and copyright law.

 

The laws of invention

 

“Creating a sport isn’t just about building a player base – patents also comes into it. A spokesperson for the Intellectual Property Office (IPO) explained to BBC Bitesize that the name of a sport can be trademarked in the UK – recent examples are Zumba, Boxercise and Spinning. Rules of the game can’t be trademarked but they can be protected by copyright, and revisiting them over time also keeps them in copyright.”

 

There is a lot to unpack here.

 

  • The focus of the is on trademarks. The names of the new sports referenced are protected by Registered Trademarks. This is fine – a trademark protects branding or trading stylisation – but these are definitively not

 

  • The rules of a game cannot be trademarked, but this isn’t really the point. What the author wants to say here is that the rules of a game cannot be patented (in the UK). Rules for a game are explicitly excluded from patentability. A patent can protect the method of a technical invention (such as a method of manufacture), but the rules of a game are deemed non-technical in nature.

 

  • The rules of a game can be copyrighted, in the sense that the literal wording of the rules codifying the game fall under the scope of copyright protection, if original. Copyright cannot protect the underlying concept of a game.

 

The confusion between trademarking and patenting is reiterated in the next paragraph:

 

“Anything unique to a new sport in terms of equipment can be trademarked. The IPO has seen patents registered for wetsuit technology linked to triathlons, with many more for equipment linked to rugby and cycling. The UK is also number one in Europe for patents regarding sports-adapted wheelchairs used in the Paralympics and other events.”

 

In this instance, I believe the author is referring to trademarks when they mean patents. The name of a piece of equipment can be trademarked, but the unique (and inventive) aspects of a product can be patented.

 

A cursory search of the patent databases finds a single British patent application to a ‘sports wheelchair’, GB2130154, which dates back to the 1980’s. It’s not clear where the assertion of the UK’s pre-eminence in the sports-adapted wheelchair technology sector arises from, but I for one would be interested to know more!

 

Bossaball

 

Potentially, some of the confusion arises from the conversation with Filip Eyckman, the creator of Bossaball. He acknowledges a tricky past with the enforcement of his IP over the years.

 

The Bossaball website directs the reader towards a page entitled ‘Patents’, which recites the following:

 

“Bossaball Sports S.L. is the owner of all rights worldwide. Bossaball Sports S.L. is protected through international copyright and additional trademark and design patents worldwide.”

 

Herein lies another common misconception about IP – the existence of the ‘design patent’.

 

A design subsists in the aesthetic (i.e. non-functional) aspects of a product. Bossaball Sports S.L. do not appear to have any patents (called utility patents in some jurisdictions, such as the US), but instead have design patents or registrations.

 

As such, Bossaball Sports S.L. IP rights portfolio would appear to comprise the following (in at least some territories):

 

  • Protection, via a design patent/registration, over the aesthetic appearance of the inflatable court, upon which Bossaball is played.

 

  • Protection, via a trademark registration, to at least the Bossaball name.

 

  • Protection, via copyright, to the written rules of the Bossaball game.

 

What Bossaball can’t do, it would seem, is prevent the unauthorised use of a game played on an inflatable court which looks different to that protected by the design patent/registration, under a different name, and not utilising a copy of the rules created for Bossaball.

 

So how do you protect a game?

 

Whilst it may seem as though Bossaball Sports S.L. have vulnerabilities in their portfolio (i.e. potential avenues for copycats to arise), the vulnerabilities are narrow in scope. The protection sought by Bossaball Sports S.L. is actually a textbook case as to how to obtain some sort of protection for a game which otherwise cannot be patented.

 

  1. Obtain design (or, if feasible, patent) protection for any equipment or paraphernalia in the game;

 

  1. Register the game name as a trademark, and build up brand awareness to improve the strength of the trademark; and

 

  1. Ensure that you have good and detailed records of copyrightable material, so as to permit enforcement of any rights available against direct copycats.

 

What you shouldn’t do is mark your concept as patented or patent pending, when you only have trademark to the brand. This is illegal, and highlights why it’s important to be selective in the terminology you use in the IP arena. So I tip my hat to BBC Bitesize for raising these points to the wider audience, whilst giving them a digital slap on the wrists for using some misleading phrasing!

 

How To Make Competitors Aware Of Your IP

by

Competitors of intellectual Property

 

It is a question that we are frequently asked: ‘I have patents and trademarks, so how do I put a notice on my products and website to notify competitors of my intellectual property rights?’

 

Whilst driving home from a recent ski trip with my family, I noticed the following on a cardboard sleeve used by Starbucks® to hold my piping hot triple-shot cappuccino:

 

Competitors of intellectual Property

 

Curiosity took me to the stated page: www.lbpmfg.com/patents/, and I liked the way this was laid out.

 

The company’s rights are clearly displayed in a table, with a picture of the product, and the trademarked name …

Competitors of intellectual Property

 

… followed by the associated patent rights:

 

Competitors of intellectual Property

 

If curious, the granted patent rights can be viewed at US8,529,723 and US9,056,712.

 

(Interestingly, their associated right US9,580,228, granted in 2017, is not listed on their web page, so it does seem that LBP Manufacturing are behind with their updates.)

 

Undertaking a manufacturing run, whilst having pending patent and trademark applications, costs money to reprint or retool once your applications are finally allowed and become granted or registered rights. This usually results in a new ‘grant’ number, particularly for patent rights.

 

To this end, having a single website address which can be referred to on your products and literature, and which can be easily updated as new rights are won and older rights lapse, will save time and costs downstream.

 

Why Do I Want To Notify Others Of My IP Rights?

 

Let’s look briefly at the UK, and also the USA to answer this question.

 

In the UK, there are provisions for at least a partial defence against infringement if the infringer can argue that they were ignorant of the existence of the patent or similar rights. See ‘Section 62(1)’ on the UKIPO’s website.

 

The onus is on the infringer to prove that they were not aware.

 

Being clearly directed to a list of your IP rights by a statement on your product or associated literature makes this defence difficult or impossible to use.

 

There are no specific requirements, under UK patent law, for a patent owner to state their rights publicly (but why wouldn’t you? You have paid for the asset, why not use it to protect your market?). Under US patent law, legal damages will not accrue until an effective notice of rights is given.

 

35 USC 287(a), since the introduction of the America Invents Act (AIA) in 2011, gives the option of ‘virtual’ marking to avoid the necessity of physical marking. Virtual marking is as shown above, where LBP Manufacturing has put a statement on their cardboard sleeve of ‘Patent’ followed by their internet address for a web page that outlines a complete and up-to-date list of associated patent rights. See Page L-67 of the MPEP from the USPTO for more specifics.

 

As alluded to above, since you have paid to stake a claim to your intellectual property, why would you not make the best use of the assets? Use the rights as a ‘keep off the grass’ sign to deter your competitors.

 

Shanks vs Unilever

by

Shanks vs Unilever

 

The Supreme Court’s judgement in Shanks vs Unilever could lead to increased costs for businesses which benefit from profitable patents. But can these costs be avoided?

 

In the UK, the right to be granted a patent for an invention which is devised in the course of an employee’s duties automatically belongs to the employer. As such, usually, there is no legal requirement for an employer to give the employee a share of the profits from the patent/invention, or even a one-off bonus. This is based on the principle that the employer takes the financial risk in filing the patent application and marketing the invention, as well as the fact that the employee is at least partly being employed to devise inventions (so why should they be paid more for doing their job!).

 

This may seem rightly just/wholly unfair depending on which side of the employer/employee divide you are on!

 

There is one main legal caveat to this – that the inventor is entitled to fair compensation if the patent/invention is of “outstanding” benefit to the employer. Of course, this raises the question of what is “outstanding”?

 

“Outstanding” has generally been seen by the courts as a very high bar to pass. The first award of compensation for an employee by the courts under this law was in Kelly and Chiu v GE Healthcare Ltd [2009]. In this case, the patented invention vastly turned around the fortunes of the employer – the company was facing a financial crisis before the patented product provided total sales between 1993 and 2007 of £1.3 billion. It seems safe to say that, in this case, the invention/patent was of outstanding benefit.

 

But the situation was far more nuanced in the Supreme Court’s more recent judgement in Shanks vs Unilever. The patent for the invention, developed by Professor Shanks whilst working for a Unilever subsidiary, provided Unilever with £24.5 million in licence fees. This is undoubtedly a large sum of money, but to a company of Unilever’s size would one describe such a sum as “outstanding”?

 

Professor Shanks’s representatives argued that if only the relative size of the financial gain were considered, then this meant that no company of Unilever’s size would ever be required to pay inventor compensation. In other words, this interpretation meant that Unilever was “too big to pay”.

 

The Supreme Court ultimately came to the conclusion that, although the benefit to Unilever might not be outstanding in absolute financial terms, it was outstanding because it came from an area of the market which Unilever was not particularly active, and came only in the form of licence fees, so the risk and effort on Unilever’s part was minimal. Professor Shanks was awarded compensation of 5% of the profits which equated to £2 million when accounting for interest.

 

The Supreme Court made the following remarks, which could well form the basis of future outstanding benefit compensation claims where the relative financial benefit of the patent/invention to the employer is not particularly great:

 

“For example, the benefit may be more than would normally have been expected to arise from the duties for which the employee was paid; it may have been arrived at without any risk to the business; it may represent an extraordinarily high rate of return, or it may have been the opportunity to develop a new line of business or to engage in unforeseen licensing opportunities.”

 

These comments, therefore, seem to provide several possible avenues for arguing that the benefit to the employer is “outstanding”, and as such may clear the way for more employee compensation claims.

 

So, what might you do if you are an employer and are lucky enough to have employees devising very profitable patented inventions, but are concerned about paying out large sums in employee inventor compensation claims?

 

There is nothing contractual which can be done to prevent an employee receiving compensation – the UK patent’s act expressly states that any clause of a contract which would prevent an employee receiving this kind of compensation is unenforceable. Nor is providing the employee with a small amount of compensation a way to prevent compensation being awarded – if the compensation is “inadequate” then the courts can still make an award.

 

Since there is no way to prevent employees from being awarded compensation, a “soft” approach would appear to be the best strategy; provide your employees with reasonable/generous rewards for devising any and all patented inventions. Not only would this provide an incentive for employees to devise further inventions are therefore generate more profit, but a happy employee might not feel the need to go looking for compensation in the instance of a particularly successful invention, and thereby avoid mutually costly court proceedings.

 

The Mathematics of Patents

by

Mathematics of Patents

 

As a general rule, mathematical methods are excluded from patentability, although practical applications involving mathematics may still be patentable (advances in cryptography, for example). However, mathematical terms themselves aren’t excluded and some of those have made their way into the lexicon of patents. Here are five common aspects of patent law involving relatives of words you might expect to find in a maths textbook.

 

1) Added subject matter, by addition (+)

 

A patent application is a snapshot of the invention at a particular point in time once it has been finalised to a large extent. Of course, you may continue improving your invention after a patent application has been filed – this happens all the time. However, you are not allowed to add any new information to your patent application to describe those improvements. If you need to make changes to the application, you can only do so using the information that was in the application at the time it was filed.

 

If the improvements to the invention are valuable in their own right, then you would need to file a new patent application to protect them. Of course, the original application may still cover your invention (unless there have been major changes), but protecting incremental improvements as well can allow you to prolong patent protection for your products beyond the 20-year patent term, and may allow you to take advantage of Patent Box tax relief over a longer period of time.

 

2) Added subject matter, by subtraction (–)

 

This is the other side of the coin to the situation above. Claim 1 of your patent application might claim “a widget comprising a first widget part, a second widget part and a third widget part”. All of these features are in the independent claim (claim 1), so they are considered to be essential to how your invention works. But what if you find that the third widget part isn’t actually essential, and keeping it in claim 1 would make for an easy workaround? Can you delete it from claim 1?

 

The answer is maybe. It depends if there is another part of the patent specification that indicates the third part is non-essential. Taking out the third part would constitute “claim broadening” (a kind of claim amendment), which is allowed before the patent grants, but not after grant. Of course, removing a feature from claim 1 could also mean that there is more prior art standing in the way of patentability, so it may be necessary to add other features in to compensate for that.

 

There is also the chance that you might need to disclaim (i.e. exclude) a particular feature or scenario to get around an objection based on prior art. Disclaimers can be based on something said in the patent application (a “disclosed disclaimer”, e.g. my widget does not include a handle), or occasionally based on something that is not said (an “undisclosed disclaimer”). This second type of disclaimer could be argued to add matter, but is essentially restricted for use in a situation where the prior art is completely unrelated, e.g. your invention is a dog toy, and the prior art involves helicopters.

 

3) Multiple embodiments (×)

 

It is often the case that an invention can be put into practice in more than one way. If you have found two or more ways to solve the same technical problem, then there are potentially multiple embodiments to describe when preparing a patent application. For example, a lever-type door handle solves the same problem as a rotatable doorknob – but one of these is only useful if you need to keep a bear in the next room.

 

Sometimes a patent examiner may decide that two or more embodiments are claimed in different enough ways that they will not perform a patent search for all of the embodiments, even if they are related to each other. There is usually the option to request a further search for the unsearched embodiments, but to obtain patent protection for those other embodiments may require a divisional application (see below).

 

4) Divisional applications (÷)

 

A patent is limited to a single invention. If your patent application includes multiple inventions, e.g. the lever and rotating door handles example mentioned above, then you may need to file a second patent application which is divided out from the first. A divisional application would be searched and examined separately and, if granted, renewable separately to the first patent.

 

A divisional application can only be filed whilst the original application is still pending (European patent applications) or usually no later than three months before the compliance deadline (UK patent applications). This is one reason why it can be beneficial not to get a patent granted as fast as humanly possible – keeping an application pending retains the option to file a divisional, which can be useful if there is infringement.

 

5) Infringement by equivalence (=)

 

An infringing product does not need to copy every single feature of a claim in a granted patent for there to be infringement. Sometimes, it is enough that an equivalent feature is provided. That is to say, patent protection isn’t limited to the literal wording of the claims – it is the claims as construed in light of the specification as a whole, and taking account of equivalent features, that determines the scope of protection and whether a variant infringes.

 

For example, in 1990, the Improver v Remington case found that a slitted rubber rod was equivalent to a helical spring, mainly because the epilator obviously worked in the same way. This was taken further in Actavis v Eli Lilly which went all the way to the UK Supreme Court, with the result that potassium was considered to be equivalent to sodium, for the purposes of interpreting the scope of the patent claims at issue.

 

For UK patents, if the variant works in the same way and achieves the same result as the invention, and strict compliance with the claim wording is not essential to the invention, then it should be found to infringe. This is assessed on a case-by-case basis though.

 

Summing up

 

The take-home messages here are that you can’t add new information to a patent application after filing, you might need to split your patent application in two (or three, or four…) to protect multiple versions of your invention, and assessing patent infringement isn’t always as straightforward as it might seem – there are a lot of factors to consider.
