EPO CRISPR Patent Appeal Resolved

by

CRISPR Commercial Patents

 

The EPO Boards of Appeal convened recently to offer a final ruling in respect of EP2771468, a patent granted to the Broad Institute in respect of CRISPR/Cas9 gene editing technology. This case has attracted a lot of attention, not least because of the potential commercial value of the patents at hand, as well as the background of long-standing disputes between the various parties holding CRISPR patents across the world.

 

What is CRISPR?

 

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology is a novel DNA editing tool which is faster, more cost-efficient, and more accurate than previous gene editing techniques. Indeed, there was some speculation that the most recent Nobel Prize for physiology or medicine might be awarded to the minds behind CRIPSR, before this was awarded to Kaelin Jr, Ratcliffe, and Semenza for their discoveries of how cells sense and adapt to oxygen availability.

 

Ultimately, the technology can be used to permit scientists to rapidly make cell and animal models for the purposes of medical research, as well as providing many options for medical diagnostics, and the techniques are widely used around the world.

 

EP2771468

 

EP2771468 was filed on 12 December 2013, as an International (PCT) application, claiming a long list of priorities to earlier US applications. The publication of grant occurred on 11 February 2015. Several oppositions were launched, starting in October 2015, which asserted that the patent was invalid.

 

The claims themselves were directed towards a composition comprising a CRISPR-Cas system chimeric RNA or a CRISPR enzyme sequence, which are modified to improve their stability.

 

The patent itself is a fairly meaty read, with the International application as published running to 162 pages. The field of technology here is one with dense impenetrable jargon (much like patent law itself!), but this is beside the point. The merits of the appeal hinged on a simple question – was the application entitled to priority?

 

Priority

 

The law of priority for patents stems originally from the Paris Convention, which recites in Article 4(A)(1):

 

Any person who has duly filed an application for a patent […] in one of the countries of the Union, or his successor in title, shall enjoy, for the purpose of filing in the other countries, a right of priority during the periods hereinafter fixed.

 

Why is this important? Well, the Broad Institute filed their original US patent application having four inventors, also named as applicants. When filing in Europe (via the PCT filing), however, one of the inventors was omitted, Professor Luciano Marraffini of Rockefeller University, New York.

 

If Professor Marraffini had not, as asserted by the opponents, assigned his right to the invention correctly to the Broad Institute by the time the European application was filed, then the Broad Institute were not entitled to claim the priority right. This meant that the effective date for the assessment of prior art changed. Here, this meant that different citations, much more destructive to patentability, became citeable, which in turn would lead to revocation of the patent.

 

EPO case law is quite clear in this regard. T788/05 clarified that a sole applicant who was one of several joint applicants on a first filing cannot give rise to a separate priority right. The right of priority is jointly owned but indivisible. The applicant of the European patent application must be the owner or successor in title to all of the rights of the individual applicants of the priority application as of the date of filing of the European application, or in this instance, PCT application, for a valid priority claim to be made.

 

Oral Hearing

 

If the EPO case law is so clear, then how did this case reach an oral hearing? Crucially, the USPTO have a different interpretation of how a valid priority right can form – the later application needs only a single inventor in common in order for a valid priority claim to be made.

 

Essentially (and in much simplified terms), the Broad Institute argued that, given that the priority applications were US filings, then US law should govern how priority can be claimed. Additionally, much semantic argument was heard about the meaning of the term any person as outlined in the Paris Convention.

 

This line of argument threatened to lead the Boards of Appeal to refer the matter to the Enlarged Board of Appeal, which would have significantly extended the uncertainty regarding the status of the patent, but eventually finalised their decision to revoke the patent, finding the priority claim invalid.

 

Procedural Strictness

 

Overall, the decision of the Board of Appeal is much as had been expected to European observers. The prevaricating over this matter has ended, and the final written decision of the Board is expected soon.

 

What can we infer from a practice perspective from this resolution, however? Primarily, whilst the direction in the UK, at least, is towards excusing sloppy claim drafting, the law of priority remains strict, to the point of being lethal to viably patentable technology. In this instance, the Broad Institute potentially have nine patents which have questionable priority claims.

 

Given the divergence of US and European law in this regard, patent practitioners need to be very aware of potential issues in respect of entitlement and ownership, and how this can have a knock-on effect on the validity of patents.

Banksy: The Flower Thrower

Banksy: The Flower Thrower

 

“Does art matter?”. On 17 October 2019 , graffiti artist Banksy launched an online shop called Gross Domestic Product to sell his branded merchandise for two weeks, the launch being advertised by a pop-up shop in Croydon, UK. To have chance at purchasing an item, would-be Banksy merchandise owners had to register their interest and answer the above tie-breaker question. The sale of trademarked merchandise, an unprecedented move by Banksy, is better understood in the wider context of a dispute surrounding one of Banksy’s trade marks.

 

Banksy is the owner of several European trade marks, registered under the name of Pest Control Office Limited, a handling service acting on behalf of Banksy. The particular European trade mark at the centre of the dispute is European Trade Mark 012575155  which protects an image reminiscent of Banksy’s Rage, the Flower Thrower mural in Jerusalem, also known as Love Is In The Air, Flower Thrower or Flower Bomber. The Flower Thrower trade mark was filed in February 2014 and registered by August 2014.

 

In a statement posted on the pop-up store in Croydon, Banksy has explained the motivation behind the shop as follows:

 

“A greetings card company is contesting the trademark I hold to my art and attempting to take custody of my name so they can sell their fake Banksy merchandise legally”.

 

Full Colour Black, the greetings card producer in question, deny that they are trying to take custody of Banksy’s name, and have stated that the company previously approached Banksy’s representatives to pay them royalties, which Banksy refused

 

Subsequently, in March 2019, Full Colour Black filed an action for invalidity to cancel the Flower Thrower European trade mark. If the trade mark were successfully cancelled, Banksy would not be able to rely on his European trade mark to prevent use of the Flower thrower image commercially and Full Colour Black would be free to sell cards featuring the Flower Thrower without any risk of infringing the mark.

 

Of course, Banksy could rely on copyright to stop Full Colour Black or any other entities who are copying his art work. However, so far, Banksy has not enforced his copyright, the likely reasons for this being that to do so would require giving up his anonymity, and the requirement to file statements of use to enforce his copyright in the USA.

 

The essential function of a trade mark is to enable consumers to distinguish the goods or services of one undertaking from those of other undertakings. As the Flower Thrower image is reproduced widely on goods sold by different entities, Full Colour Black have argued that the image is not capable of being a trade mark. This is because it does not allow consumers to distinguish the goods originating from an undertaking under Banksy’s control and those originating from other companies. This is particularly true, as, prior to the launch of the shop in October 2019, no official Banksy merchandise existed. Furthermore, Full Colour Black argue that Banksy has registered the mark with no intention to genuinely use it, which amounts to bad faith, a further ground for invalidity.

 

It is unclear how selling trademarked merchandise is supposed to help Banksy’s case, as evidence of use has no effect in an invalidation action. The sale would be much more understandable if the action filed by Full Colour Black had been for revocation, as a trade mark can be revoked for non-use.

 

According to European trade mark law, a trade mark can be revoked, upon application to the European Union Intellectual Property Office,

 

“a) if, within a continuous period of five years, the trade mark has not been put to genuine use in the Union in connection with the goods or services in respect of which it is registered, and there are no proper reasons for non-use; […]”

 

(Article 58 of the EU Regulation No 2017/1001 of 14 June 2017)

 

In other words, as Banksy had not sold any goods to which the Flower Thrower trade mark was applied, and for which the trade mark was registered between August 2014 and August 2019, and there were no reasons preventing him from doing so, his Flower Thrower European trade mark became subject to revocation in August 2019 such that Full Colour Black could have applied for revocation from then on.

 

However, the law does also state that:

 

“no person may claim that the proprietor’s rights in an EU trade mark should be revoked where, during the interval between expiry of the five-year period and filing of the application or counterclaim, genuine use of the trade mark has been started or resumed; the commencement or resumption of use within a period of three months preceding the filing of the application or counterclaim which began at the earliest on expiry of the continuous period of five years of non-use shall, however, be disregarded where preparations for the commencement or resumption occur only after the proprietor becomes aware that the application or counterclaim may be filed;[…]”.

 

In short, the shop launch in October 2019 may have been an attempt by Banksy to pre-emptively invalidate any revocation action filed by Full Colour Black.

 

Such a revocation action would nevertheless remain admissible if Banksy only launched the shop after becoming aware of the possibility of a revocation action being filed against his trade mark and if such an action were filed within three months. Whether the sale of a few items for a limited period of time constituted genuine use of the mark is also an important question.

 

The current status on the European Union Intellectual Property Office register of Flower Thrower European trade mark 012575155 is “registration cancellation pending”, as the court determines the matter.

 

In a parallel move, Banksy’s legal team appear to have filed another representation of the Flower Thrower as a new European trade mark application in August 2019, European trade mark application 018118853. This new trade mark application is currently undergoing examination. If registered in due course, the sale of branded merchandise in October 2019 may well have been a move to demonstrate use of the image submitted in the newly-filed European trade mark application, rather than in response to the invalidation action. Of course, if the first Flower Thrower trade mark is invalidated (and therefore was never a valid registered trade mark), this may not bode well for the registration of the second Flower Thrower trade mark application, or indeed the registration of many other of Banksy’s image trade marks.

 

It will be interesting to see how this case develops further.

 

An important, practical conclusion for trade mark owners to draw from this case is to not wait five years before putting your trade mark to use. Otherwise, your trademark will become open to being revoked for non-use.

 

If you have not been using your mark in the last five years or more, the most advisable course of action in many cases would be to resume or start as soon as possible.

 

If in doubt, please do not hesitate to contact Albright IP for advice about your trade mark.

 

Bentley v Bentley – The Peril of New Markets

by

 

On 1 November 2019, Judge Richard Hacon in the High Court finally settled a 20-year long dispute between one of the world’s most prestigious and recognizable car brands, and a small Manchester based UK clothing company.

 

The background of this case is as follows. Since circa 1987, the Defendant, Bentley Motors Limited (“Bentley Motors”), has been extending use of their famous ‘B-in-Wings’ Trade Mark to clothing and clothing accessories. The Claimant, Bentley 1962 Ltd (“Bentley Clothing”), a UK based manufacturer and retailer of clothing, began selling clothing under the BENTLEY Trade Mark in 1962. The two sellers coexisted without apparent contact until 1998, when Bentley Clothing approached Bentley Motors to offer a licence for the use of their Trade Mark. The terms of the licence were not agreed, and talks broke down.

 

The situation escalated in the early 2000’s when Bentley Motors began using their ‘B-in-Wings’ Trade Mark in conjunction with the word ‘Bentley’ (“the Combination Mark”) on clothing and clothing accessories.  Further contact was made between the parties but to no satisfactory conclusion. Over the course of the next few years, Bentley Motors increased their use of the Combination Mark on clothing, despite being on notice of Bentley Clothing’s rights in, and use of, their BENTLEY Trade Mark in the same marketplace. Between 2005 and 2017 the two parties faced off numerous times before the EU and UK Intellectual Property Offices. Despite the length and cost of the proceedings, Bentley Clothing could not reach an agreement with their heavyweight opponent, and as a consequence, Bentley Clothing were left with no other option but to issue High Court proceedings against Bentley Motors for Trade Mark infringement. The result being a success for Bentley Clothing in its allegation of infringement (with damages and costs to be established at a later date).

 

This case highlights the potential dangers of brand extension from one marketplace; where the proprietor’s Trade Mark is incredibly distinctive and well-known, into a new marketplace, where the average consumer may not recognize that the relevant goods are associated with that particular proprietor. The effect being potential confusion in the market, as shown in this present case. Bentley Motors could be forgiven for thinking that their brand was too powerful to ever be challenged, even in a commercially distant market from the one that they are currently associated with. The long and slow encroachment by Bentley Motors into the clothing sector, despite being on notice of the existence of Bentley Clothing’s prior rights, seems to demonstrate a reckless arrogance. This loss for Bentley Motors shows that even large, reputable Trade Mark proprietors must approach brand extension with caution. Stepping out of an established market sector into a new area comes with risks.

 

The risks associated with brand extension can be mitigated with careful and considered research into the landscape of the relevant new market (Trade Mark registries and simple online searches are a good place to start), and being open to a meaningful discussion with competitors at a business to business level when a potential for conflict is spotted, is paramount in avoiding lengthy battles. In this case, if the discussions between the parties had not been allowed to break down, and if Bentley Motors had taken seriously the protection afforded by Bentley Clothing’s Trade Marks, it seems very likely that this dispute could have been settled long before it reached the High Court.

 

The High Court’s Decision can be appealed, and it will be interesting the see if Bentley Motors will continue the fight. Whether it’s sports or Intellectual Property, the press and the public love a good underdog story, and this one appears to be no different.

EPO to change Rules of Procedure of the Boards of Appeal

by

EPO rules changes

 

The European Patent Office has recently approved the revised Rules of Procedure of the Boards of Appeal (RPBA) which will come into force to any pending or newly filed appeals relating to European patents or applications from 1 January 2020 onwards. This article provides a brief overview of the more important rule changes, governing the appeals procedure, and what they mean in practical terms.

 

According to the EPO, the new RPBA aims to increase “(i) efficiency, by reducing the number of issues to be treated, (ii) predictability for the parties and (iii) harmonisation”.

 

Following the rule change, parties will typically be given at least four months’ notice for oral proceedings. A decision will be issued within three months of the oral proceedings (or if later, parties will be informed of that date).

 

According to Article 10, it is now possible for an appeal to be accelerated on request by a party. Grant of the acceleration is at the EPO’s discretion and reasons justifying the acceleration, such as infringement proceedings, and supporting evidence should be provided with the request. It is now also possible for the EPO to accelerate proceedings of its own motion.

 

Another significant rule change in Article 12, paragraphs 4 to 6, sees restrictions on new requests, facts, lines of attack, arguments, and evidence being admitted during appeal proceedings. The new RPBA further emphasises that the primary object of the appeal proceedings, which is to review the contested decision rather than retry the case.

 

Furthermore, any part of a party’s case which does not relate to the material on which the contested decision was based will only be admitted into proceedings at the discretion of the EPO, according to new Article 13. Amendment to a party’s case after filing of its grounds of appeal or reply can only be admitted at the EPO’s discretion, taking into account whether the amendment is suitable to resolve the issues concerned and procedural economy. The bar is set even higher for an amendment made at a very late stage of proceedings – it will not be taken into account unless there are exceptional circumstances justified with cogent reasons.

 

Exceptions to the Application of the new RPBA

 

There are certain circumstances to which the new RPBA do not apply:

 

– Article 12, paragraphs 4 to 6, in particular, will not apply to any statement of grounds of appeal filed before 1 January 2020; or

 

– if a summon to oral proceedings or a communication under Rule 100(2) EPC (invitation by the EPO to file observations during examination of the appeal) is issued before 1 January 2020.

 

Practical Implications

 

It is more important than ever to ensure anything you may wish to rely on is included in the proceedings as early as possible. This applies to cases already in the appeal process and is also likely to be pertinent to cases that are appealable, such as cases in examination or opposition proceedings.

 

For cases already in appeal, it makes sense to submit any material you may wish to rely on, and certainly any grounds of appeal or replies, before 1 January 2020.

 

Care should also be taken to ensure all relevant facts, lines of attack, arguments and evidence, as well as any material that may be helpful, are on file for cases in opposition or examination proceedings. You want to reply on these materials if an appeal is necessary in the future.

 

The new RPBA will likely encourage the front loading of appeal proceedings as well as comprehensive preparation of the file for first instance proceedings to pre-empt any possible appeal in the future.

Get Out On The Highway – What exactly is the PPH programme, and is it worthwhile?

by

PACE vs. PPH

 

The European Patent Office (EPO) has announced as of July 2019 that the Patent Prosecution Highway (PPH) pilot programme with IP Australia is to be extended to June 2022.

 

In total, this means that the EPO has PPH programmes in effect with fifteen other patent offices. The relevant jurisdictions are: United States of America; China; Japan; Korea; Australia; Brazil; Canada; Colombia; Israel; Malaysia; Mexico; the Philippines; Russia; Singapore; and Eurasia.

 

What exactly is the PPH programme, and is it worthwhile?

 

Earlier Work Products

 

The PPH programme allows a later office to rely on ‘available work products’ from one of the partner offices, which indicates that the claims of the application are allowable.

 

This allows the EPO to fast-track the grant process of the European patent application, based on the earlier work product.

 

Requirements

 

There are specific requirements for participation in the PPH programme.

 

  1. The priority date or filing date of the earlier application must match that of European application to undergo PPH acceleration.

 

  1. The earlier application must have at least one claim therein indicated as allowable.

 

  1. The claims of the European application must be made consistent with the allowable claim(s) of the earlier application. A claims correspondence table should be provided as part of the request for PPH at the EPO.

 

  1. PPH must be requested before the EPO begins examination of the European application.

 

Effectively, the PPH programme allows the prosecution of a pending European application to catch up with that of an application in another jurisdiction, provided that the EPO has not already started examination on its merits.

 

Should I Use PPH Acceleration?

 

The EPO acknowledges that a valid PPH request will put the application into a fast-track stream, on a par with a standard request for acceleration under the PACE programme.

 

This is interesting, since there is a significantly lower administrative burden on the applicant for filing a PACE request than there is for filing a PPH request, with no apparent change to the potential timeframe to grant.

 

What is also worth noting is that the EPO Examiner is still required to assess the merits of the compliance of the European application with the requirements of the European Patent Convention. PPH acceleration does not guarantee grant – it is not a rubber-stamping exercise. The EPO has different requirements for grant when compared with, for example, the USPTO or KIPO. The EPO requirements with regards to added-matter are commonly regarded as being stricter than in some other jurisdictions

 

PACE vs. PPH

 

Therefore, there may be different factors to consider when deciding whether to request PACE acceleration or PPH acceleration.

 

  • I want to bring my European application into alignment with an already-granted patent in another jurisdiction.

 

  • In this scenario, it would seem prudent to allow the EPO to access the prior work product of the earlier office, in order to streamline grant. Provided there is no obvious reason that the application contravenes the EPC, then PPH acceleration would seem appropriate.

 

  • I have a patent in another jurisdiction, and want to align some, but not all, of the features of the European application with the granted patent.

 

  • In this situation, we would not want to just accept the allowed claims from the earlier office. As such, PACE acceleration would seem more applicable.

 

  • I have a granted patent in another jurisdiction, but I have already responded to one examination report in Europe.

 

  • A PPH request would be invalid here. PACE acceleration of the examination process could still, however, accelerate the route to grant. The timeframe between examination reports can be substantial under European procedure.

 

  • I have a granted patent in another jurisdiction, but I am not sure whether the claims would be valid in Europe.

 

  • The best thing to do here would be to assess the claims for compliance with the EPC first, potentially aligning the ‘spirit’ of the claims with those as granted overseas, and then just requesting PACE acceleration. This may shorten the examination procedure, given that any deficiencies in the claim set may be addressed first. This may not be possible in a PPH request.

 

Overall, there are scenarios in which a PPH request may be a useful tool to quickly obtain grant of a European patent. However, the more straightforward PACE scheme provides the same benefits of acceleration, without many of the restrictions associated with a PPH request.

 

The important thing is to remember that the application must still meet the requirements of the EPC for a valid patent to be issued, in particular, with regards to inventiveness and added subject-matter.

Can I wait to file a patent application?

by

Can I wait to file a patent application?

 

For start-ups that are building their business around an innovative product, preventing more established companies from copying their idea by having a patent granted is essential. However, there are plenty of other essential aspects of a business which need attention when just starting out.

 

Therefore, is it possible for a start-up to defer filing a patent application, to allow funds to be spent on other areas of the business?

 

Why would I not be able to wait?

 

One of the chief requirements of obtaining a patent is “novelty”. Therefore, your idea must be completely new compared to what is already publicly available at the time of filing the patent application.

 

In general (read on to find a notable exception), patent offices do not distinguish between who made the idea available. Therefore, if you wait to file a patent application and start selling or marketing your product beforehand, then you may be prevented from obtaining a patent.

 

Even if you are not intending to publish or market your product just yet, someone else may have come up with a similar idea. Waiting to file your patent application increases the chance of someone else disclosing or filing for a similar idea – preventing you from obtaining a patent to that idea.

 

“Enabling disclosure”

 

To destroy the novelty of your invention, you would need to publish enough information to allow someone to recreate your invention.

 

In the case of a physical product, selling the product would likely destroy your chances of protecting the product itself. However, the method used to make the product may be the clever idea you want to protect.  If this method is not discernible from looking at the product, and if you have kept the method confidential, then you may still be able to protect this, even after launching. Additionally, if you only publish pictures of the exterior of your product (for example for crowdfunding campaigns), and these do not reveal how the product works, then you may still be able to obtain a patent to the workings of the invention.

 

In the case of an app, if the clever way the app works is locked away behind the scenes and is not apparent from the software which is distributed, then it may still be possible to protect this aspect of the app, even after launching.

 

In the above examples, it would be crucial that the method of production and working of the app be kept confidential. Non-disclosure agreements should always be used if such information must be disseminated to potential business partners or developers.

 

The notable exception

 

The United States (among a small number of other countries) provides a 12-month grace period for inventor disclosures. Therefore, if you publish your invention, this publication and any third-party publications going to the same published material won’t work against your US patent application. This is as long as you file for a patent within 12 months of your first publication.

 

However, other key markets (such as the UK, Europe and China) do not have such grace periods, so this strategy would result in a loss of ability to obtain protection in these markets.

 

Design protection

 

Whilst the UK and Europe do not have a grace period for patents, they do have a 12-month grace period for registered designs. Therefore, if you are only interested in protecting the way your product looks in these territories, you can market your product first, and file for a registered design within 12 months.

 

However, this strategy is not without risks as your registered design can be knocked out if a third party independently derives and publishes the same or a similar design before you file your registered design.

 

Additionally, China, among some other countries, do not have such design grace periods.

 

Conclusion

 

As a general rule of thumb, do not wait to protect your intellectual property (IP), whether that is by way of a patent, trademark and/or design. The IP in your business can be one of the most valuable assets within a few years. Stake your claim to it before someone else does.

 

Furthermore, selling or marketing your invention before filing a patent application would usually prevent you from obtaining a patent downstream. However, if the concept of your invention is not discernible from the product you sell or market, it may still be possible to protect it even after launch. But this is risky. Determining whether and where protection can be obtained in these instances can be complex.

Camborne Trevithick Day – 27th April 2019

by

We are pleased to be supporting Camborne Trevithick Day on 27th April 2019.  This annual celebration commemorates Camborne’s most famous son, prolific inventor Richard Trevithick.  The first commercially useful steam engine was developed in 1712 by Thomas Newcomen, and improved by James Watt and others throughout the 18th century.  By the time Richard Trevithick began his professional career steam was already powering the industrial revolution – but Trevithick made critical improvements to efficiency and demonstrated the first working steam locomotive.  This laid the groundwork for George Stephenson’s famous locomotives and the development of the railway in the UK and around the world.

Full details of the event, including how to get there and where to park, may be found at the organiser’s website http://trevithickday.org.uk/.  Perhaps you will be inspired – as Cornwall’s newest patent attorney firm, we certainly hope that Richard Trevithick is not the last great inventor from Cambourne!

In the meantime, we thought it would be interesting to look at the legal side of Trevithick’s career.

Trevithick seems to have spent rather a lot of time trying to navigate patent law.  Initially, it was someone else’s patents – those of James Watt – which proved to be a thorn in Trevithick’s side.  As long ago as 1624, the law had set a maximum term for patents, but Watt managed to get an Act of Parliament to extend his protection for “A method of lessening the consumption of steam in steam engines” until 1800.  The nub of Watt’s patent was the separate condenser, something which led to improved fuel economy over the old Newcomen engine.

Towards the end of its extended term, it appears that Watt’s patent was being widely ignored in Cornwall, with various mining engineers adding separate condensers to old Newcomen engines.  Watt sued and, in theory at least, eventually won.

The expiry of the Watt patent in 1800, coinciding with Trevithick’s own pioneering use of high-pressure steam, represented an opportunity, and his experience with Watt had no doubt left an impression. There is a story – probably completely unverifiable – that on being served with an injunction Trevithick held Watt’s lawyer upside-down over a mineshaft.  Trevithick evidently did not gracefully accept defeat but had surely learned the power of the patent.  What’s more, the litigation over Watt’s patent lead to the important legal principle that a valid patent could be granted for an improvement to a known machine. Trevithick could turn this to his advantage.

After refining his high-pressure engine, Trevithick naturally sought to obtain his own patent.  In January 1802, with his cousin and business partner Andrew Vivian, Trevithick went to London and asked around for someone who knew how to get one.  This does not seem to have been an easy job and required personal attendance at multiple offices.  Trevithick was a busy man, visiting Merthyr Tydfil and Coalbrookdale in the same year, so it was Vivian who took his place in London and in March 1802 wrote to report that he “must call at the Patent Office for the great knob of wax”.  In those days there was no actual examination of a patent application to check that it was for a new invention, but the Patent Office made up for this in impressive bureaucracy.  Nowadays you get the photocopied signature of a middling civil servant in place of that great knob of wax.

Trevithick also took Watt’s lead when it came to charging for the use of his now patented invention.  Like Watt, Trevithick agreed with mine owners that he would be paid a percentage of the money saved on coal by the use of his modern and efficient high-pressure engines.  Unfortunately, after returning from his tour of the Americas, Trevithick found that his customers had simply stopped paying, variously claiming that they thought the patent had expired, or that it did not cover some variation in the boiler design. Trevithick managed to negotiate with a few, but – unlike Watt this time – did not pursue the matter in Court.

Trevithick nevertheless filed for patents throughout his career, ending up with fourteen to his name.  His first patent, of 1802, was numbered GB2599, in a sequence that starts with GB1 of 1617.  By the time Trevithick had obtained his last patent in the year before his death, the number was at GB6308.  More patents had been filed in Trevithick’s career than in the 200 years previous.  The age of technology had certainly arrived.

How Disclosing Your Invention Can Prevent You From Obtaining a Granted Patent

by

 

Starting a business is an exciting adventure to embark upon. Unfortunately, Intellectual Property (IP) is too often an after-thought and mistakes made early on in the process can be detrimental to obtaining IP rights.

 

Take patents for instance. In order to obtain a granted patent in the UK, at the time of filing a patent application, the invention must be novel (i.e. unknown in the whole world) and inventive (i.e. not obvious).

 

Looking more closely at the novelty requirement in the UK, the Patents Act 1977 states that:

 

“(1) An invention shall be taken to be new if it does not form part of the state of the art”,

 

and defines the state of the art as comprising:

 

“all matter (whether a product, a process, information about either, or anything else) which has at any time before the priority date of that invention been made available to the public (whether in the United Kingdom or elsewhere) by written or oral description, by use or in any other way” (see section 2 of the Patents Act 1977).

 

In essence, disclosing your invention publicly could prevent you from obtaining a granted patent because your invention will not be considered to be “new”.

 

So how do I know if I’ve publicly disclosed my invention?

 

You are likely to have disclosed your invention publicly if, before filing a patent application, you have:

  • Talked to investors, business partners, friends, or potential clients about your invention
  • Blogged, vlogged, tweeted, written about or posted images of the invention on a social media platform
  • Got a Kickstarter page in which the invention is disclosed
  • Posted a document about your invention on a website
  • Been on Dragons’ Den
  • Given a talk to an audience or displayed a poster at a conference,
  • Published a book or thesis which is on open shelves in a public library, even if no-one has ever read the book
  • Published an article, an abstract, or a grant proposal
  • Given away or sold samples
  • Shown your invention at an exhibition (with some exceptions)
  • Used the invention in a public place

 

There are, however, caveats to be voiced about the above list.

 

Confidentiality

 

Any disclosure in confidence, for example under a Non-Disclosure Agreement (NDA), will not be considered as a public disclosure. For a free, template Non-Disclosure Agreement, please click here.

 

Please note however, that any IP-related discussion you have with a chartered patent attorney or trademark attorney in the UK, such as those here at Albright IP, will be considered as confidential (i.e. not public), without you needing to sign an NDA first. This is because legal advice privilege applies to chartered patent and trademark attorneys.

 

Website postings

 

With regards to website disclosures, the European Board of Appeal provided the following two-step test to clarify when posting a document on a website constitutes a public disclosure.

 

If, before the filing or priority date of the patent or patent application, a document stored on the World Wide Web and accessible via a specific URL

 

(1) could be found with the help of a public web search engine by using one or more keywords all related to the essence of the content of that document and

 

(2) remained accessible at that URL for a period of time long enough for a member of the public, i.e. someone under no obligation to keep the content of the document secret, to have direct and unambiguous access to the document,

 

then the document was made available to the public […].

 

Therefore, if you post about your invention online, and if your posting remains online long enough and can be found by typing keywords into a public search engine (such as Google®), then the posting can be cited against your own patent application.

 

You should also, therefore, assume that the same approach will be taken by the UK Intellectual Property Office.

 

Emails

 

In a related case, the European Board of Appeal decided that the act of sending an email via the Internet does not constitute publicly disclosing the email’s contents.

 

Keep in mind, however, that the recipient of an email disclosing the invention needs to be under a confidentiality agreement – otherwise, the email contents could be considered as a public disclosure.

 

I think I’ve disclosed my idea publicly. Does that mean I can’t get a patent granted anymore?

 

Not necessarily.

 

To count as public disclosure, the disclosure also needs to be “enabling”. This means that enough detail needs to be disclosed so that someone “skilled in the art” could deduce how the invention works, for example, see Lux Traffic Controls Limited v Pike Signals Limited [1993] RPC 107, 132-135.

 

If your public disclosure is enabling, it may invalidate only part of your patent application. For example, you may have disclosed how the invention works but not how the invention is made. In this case, you may still be able to get a granted patent for the method of manufacture.

 

Where you have publicly disclosed everything about your invention, then patent protection in the UK or in Europe may no longer be an option. However, in some countries outside of the UK and Europe, you might still be able to rely on a grace period to get a patent granted, for example, in the USA. Alternatively, you may still be able to obtain another form of intellectual property in the UK or in Europe such as a registered design, due to the existence of a grace period.

 

Finally, it is worth highlighting that a public disclosure will only be detrimental if it is done before filing a patent application containing all the details disclosed.

 

In summary, avoid disclosing anything about your invention before you file a patent application, and make sure that any disclosure is done in confidence. If you are unsure on what to do, you can always talk to Albright patent attorneys or trademark attorneys for IP-related advice.

 

Mitigating the Effects of Prior Unpublished Patent Applications

by

 

Prior art searching is one of the most difficult things to get right in the IP sector, since any search is open-ended. How do you know whether there is a knockout document which discloses something identical to your invention that has just not been found, or whether it just does not exist?

 

This issue is compounded for patents by the publication cycle. Almost all patent applications are secret for the first eighteen months of their lives, and therefore have the potential to act against later-filed applications.

 

The prospective patentee is therefore presented with an unpleasant uncertainty – even the most thorough search cannot guarantee validity if unknown non-public prior art is available. Given that preparing and filing a patent application can involve a significant outlay of initial resources for start-ups, this can be very off-putting.

 

The British Process

 

It is worth, at this stage, outlining just what happens to a British patent application once filed.

 

From the date on which the application is filed, the claimed invention is ‘patent pending’. However, only a few morsels of information are visible on the UK Intellectual Property Office Register.

 

Provided the interim steps are taken, in particular, submitting formalised drawings suitable for publication, then the application will publish in full eighteen months from the date of filing or priority, which allows third parties to inspect the content of the application.

 

Critically, though, the first person (or their successor) to apply for a patent to an invention is the only person to whom the patent can be granted. This is known as the ‘first-to-file’ system, rather than ‘first-to-invent’.

 

Double Patenting

 

This secrecy creates an inherent problem. A patent is a monopoly right, but since the applications are secret when filed, it is feasible that lots of people could independently arrive upon the same idea, and want to patent it before any of the pending applications become public.

 

To offset this issue, prior-filed or prior-priority but unpublished patent applications are deemed relevant to the patentability of later-filed applications, for the purposes of novelty (i.e. uniqueness) only, provided that the application was filed in the same jurisdiction. Such a document cannot be cited against the inventiveness of a later application.

 

This provision in the law is specifically designed to prevent ‘double patenting’, that is, two patents being granted to the same invention.

 

This provides some comfort to prospective patentees. An unpublished document can only be used to attack the validity of any later-filed patent application in very specific circumstances. It would be unjust for the unpublished document to be deemed relevant to inventiveness (i.e. obviousness), when the skilled person could not rely on that information at the time of applying for their own patent.

 

Hunting for information

 

Whilst full patent applications are not available until the date of publication, there is some information available regarding patent applications which have been filed.

 

Every Wednesday, the UK Patents Journal is published, which has a list of patent applications which have been filed recently. The visible information includes the date of filing, the name of the applicant, the title of the invention, and the application number.

 

Whilst this is a very minimal amount of information, it does allow some level of monitoring to be undertaken to see whether competitors are filing patent applications themselves, and to what type of technology. It also allows you to keep track of the status of the application over time where applicable.

 

Strategies for minimising surprises

 

If you are considering filing a patent application, you may want to take the following steps to avoid unpleasant surprises downstream:

  1. Ensure that full patent searches are conducted prior to filing a patent application so that relevant prior art documents can be uncovered in advance. See our earlier articles on how best to go about conducting free patent searches.
  2. Keep an eye out for competitors’ product launches, and monitor the patent journal for applications which have been filed shortly in advance of the product launch. This may give you an idea of the sort of things that they are looking to protect, and you then may be able to foresee potential difficulties.
  3. File early! As soon as you are ready, and have the necessary technical information to warrant filing a patent application, you should do so. Delaying increases the risk of third parties filing their own applications before you.
  4. Ensure that you have thought through optional embodiments of your invention, or other clever features which may be important. The more technical information that is provided about these features from the outset, the greater the likelihood that you will have options for overcoming surprises during the examination procedure of the application.

 

As patent attorneys, we try and provide you with a flexible application which can withstand the rigours of examination, so that if close prior art documents are found, you have options for still getting some form of patent granted, so that initial risk does not become a lingering concern as you grow your business.
