Was a pleasure to work with Will and Melissa on a patent draft and filing.... Will took the time to understand both my software product and the commercial motivations behind the patent filing. They were extremely responsive to questions and clarifications throughout the process (availability isn't everything, but it certainly helps!).They were also very clear regarding fees, and set out a very helpful visual timeline and cost breakdown on the whole patent application process at the pre-sales stage. This emphasis on making sure I understood all aspects of the work, and having documentation to help with that, is something I didn't see with any of the other patent services I was talking to at the time. This clear communication continued throughout our interactions.Would recommend Albright IP to anyone looking to patent an invention. The patent they filed for me was for a software more

Get ready for an UPComing UPheaval in European Patents

Change is on the horizon for the European patent system.

How the system works now

Currently, a “classic” European patent application is prosecuted centrally in one language (English, French or German) at the European Office. Once the European patent grants, the European patent needs to be converted, usually within three months, into national patents in each desired European country which is part of the European Patent Convention or EPC – currently 38 countries – a process called validating the European patent.

Typically, patent owners decide to convert their European patent in only a handful of the possible 38 European countries – usually their most important markets and/or country(ies) of manufacture.

Overall, each national patent is independent of other national patents converted from the same European patent. The patent owner pays a renewal fee annually for each national patent they wish to keep in force. Alternatively, they can opt to let one or more national patents lapse by not paying the renewal fee to the relevant patent office.

Similarly, enforcing their national patent is done at the relevant national court. Thus, it is possible to invalidate a, say, French national patent and/or bring infringement proceedings in France, without the corresponding British national patent being affected.

A New Option On The Table           

On 18 January 2022, Austria deposited its instrument of ratification of the Protocol on Provisional Application of the Unified Patents Court. This started preparations for two new but interconnected systems which will most likely be coming into force in 2022: the Unitary Patent (UP) and the Unitary Patent Court (UPC). All that remains for these two systems to come into force – in addition to lots of paperwork and planning behind the scenes – is for Germany to also deposit its instrument of ratification; expected as early as June 2022, although as of 10 June 2022, nothing has happened yet here. Watch this space.

This would start a four-month “sunrise period”. The UP and UPC will then come into force on the first day of the fourth month thereafter (the end of the sunrise period), i.e. potentially as early as 1 October 2022.  As the sunrise period ends, a new period will start: the transitional period. The transitional period will last a seven years, possibly extended by a further seven years.

Unitary Patent          

Looking at the Unitary Patent first, the process up until grant of a European patent by and large remains the same as the current system. After grant however, a patent owner can either opt for the “classic” national patents mentioned above or a single, new patent under the UP.

The details are still being worked out but to date, it would appear that within one month of publication of the mention of grant, the (or each) patent owner (or their patent attorney) will need to request the conversion into the UP.  Providing all the requirements are met, the unitary patent will be a single patent, administered by the European Patent Office, having unitary effect throughout the countries that have signed up to UP – 17 countries so far out of the possible 25.

Currently, the countries part of the UP club are: Austria, Belgium, Bulgaria, Germany, Denmark, Estonia, Finland, France, Italy, Lithuania, Luxembourg, Latvia, Malta, Netherlands, Portugal, Sweden, and Slovenia. Cyprus, Czech Republic, Greece, Hungary, Ireland, Romania and Slovakia have not yet ratified but this may change in future. Note that the scope of a Unitary Patent is not extended retrospectively when new countries ratify the UPC agreement.

Notable exceptions to the UP club include Spain, Croatia and Poland who have indicated that they will not ratify the UP. As the Unitary Patent is only available to European Union countries, the UK, Norway, Albania, Iceland, Liechtenstein, Monaco, North Macedonia, Serbia, San Marino, Turkey and Switzerland will also never be part of the UP club. If wanting patent protection in countries that are not part of the UP, the patent owner will need to validate their granted European patent under the classic route.

For example, say a patentee wants patent protection for all 17 countries who have signed up to the UP, plus Ireland (which has not yet joined the UP club) and the UK, the patentee has two options:

Option 1 – validate their European Patent in all 19 countries separately under the classic route,


Option 2 – request a UP for the 17 countries and validate their European Patent in Ireland and the UK separately.

Patentees wanting both options could even explore the option of a parent patent as a UP, and a divisional “classic” patent, provided double-patenting issues are addressed.

Unitary Patent Court (UPC)

The Unitary Patent Court is a new court system being set up to rule on actions such as infringement, revocation, and declarations of non-infringement. The UPC will have courts of first instance, notably in Paris specialising in general matters, and in Munich specialising in engineering matters. A third court of first instance, specialising in Biotech/Pharma, was planned for London but this was scrapped following Brexit.  A court of appeal will be located in Luxembourg, whilst the CJEU will oversee all the courts.

Classic European patents will by default be subject to both the jurisdiction of a national court (as is currently the case) but also the UPC, at least during the transition period. However, patentees not wanting to be subjected to the jurisdiction of the UPC can “opt-out” to the classic European patent. Opt-out requires that no action has been brought against the classic European patent at the UPC. Should the patentee change their mind about opting-out, the opt-out request can be withdrawn (but this is a one-time opportunity). Similarly, the patentee only gets one opportunity to opt-out – the patentee cannot keep changing their mind.

All Unitary Patents will be automatically subject to the jurisdiction of the UPC – there is no option to opt out a UP from the UPC jurisdiction. But if no unitary effect is wanted, no need to file a request for a UP.

Requirements to obtain and maintain a Unitary Patent  

Certain requirements must be fulfilled to obtain a Unitary Patent:

  1. The request for a Unitary Patent must be filed only after the UPC Agreement has entered into force, however, it may be possible to request a delay of grant so as to be able to request unitary effect and/or submit an early request for unitary effect.
  2. The European patent must have been granted with the same claims in respect of all 25 European Union states.
  3. The designations of all 25 European Union states must be present upon grant (even if only 17 countries have presently ratified). In other words, if a single European Union designation is missing, the unitary effect cannot be requested.
  4. The request for unitary effect must be filed within one month after the publication of the mention of grant. There is no official fee.
  5. During the transitional period, a translation of the whole patent will need to be filed with the request for unitary effect. The language of translation depends on the language of prosecution of the European patent application. If the European patent application was prosecuted in French or German, an English translation is required. If prosecuted in English, any language of any other European Union state may be chosen. Beyond the transitional period, no translation is likely to be required.
  6. A single renewal fee will need to be paid annually at the EPO in euros. The three-month renewal period and the six month grace period are likely to be the same as for pre-grant renewals.

Pros and Cons of the UP vs classic EP patent

As an applicant of a European patent application, what are the pros and cons of each system?


Considering the Pros and Cons of each system, it is not clear how popular the new UP and UPC will be. Only time will tell. But if you are an applicant of a European patent application, you will need to consider sooner or later which system is best for you and your business!

So start thinking now about which territories are of interest, given the short deadline after grant and the requirements (including preparing a translation of the whole patent) that need to be met by then to obtain a UP patent. If your patent application is close to grant but you find a UP is wanted, delaying grant may be possible so as to be able to get a UP patent.

Conversely, start thinking about opting out now if the UP is not for you.
