A few weeks ago the UPC Blog was asked these questions « How is the UPC going to ensure legal certainty between the entry into force of the Unified Patent Court Agreement and the moment European patent holders or holders of a European patent with unitary effect obtain -for those who wish- an opt-out?” “ What happens when you rely on one of these patents which are under national jurisdiction until the entry into force of the UPCA (Unified Patent Court Agreement), and then go back to national jurisdiction after the opt-out?”
The Opt-out is definitely one of the most challenging area of the UPCA, and we have in this blog been paying a particular attention to this subject -you can find more information about the Opt-out here– and in this post we will focus on the relationship between the opt-out, legal certainty and the rights of prior users.
As explained in our previous posts, the opt-out will be available to European patent holders during the transitional period, which will start after the entry into force of the UPCA and will last for seven years (art 83.1). This transitional period might be renewed for a further seven years if the Administrative Committee considers it after consultation necessary (art 83.5).
Once a European patent holder has decided for an opt-out, it will need to be notified and registered. The opt-out will become effective on the day the notification of the opt-out is received by the Registry, provided that the opted-out patent is not the subject of a pending litigation. The Contracting Member States and the Preparatory Committee however still have to look into the necessary arrangements to achieve this. The opt-out will then be effective for the lifetime of the patent except if the patent holder withdraws the opt-out pursuant to art 83.4 UPCA, provided that no action has been brought before a national court.
It is here necessary to differentiate between the transitional period and the opt-out period. In fact if patent holders can only opt-out of the UPC jurisdiction during a renewable period of seven years, the opt-out will on the other hand last for as long as the patent exists.
But which rules will govern the use and/or infringement acts of an EP which happened prior to the opt-out? How is legal certainty maintained between the entry into force of the UPC Agreement and the notification and registration of the opt-out? In fact there might be for some European patents a moment where they fall under the UPC jurisdiction until the patent holder decides and registers the opt-out, putting them back under national jurisdiction. How then is fairness ensured for prior users of European patents?
Article 28 of the UPCA clarifies this situation for prior personal use: “any person, who, if a national patent had been granted in respect of an invention, would have had, in a Contracting Member State, a right based on prior use of that invention or a right of personal possession of that invention, shall enjoy, in that Contracting Member State, the same rights in respect of a patent for the same invention.” Hence, prior user rights will be governed by national law, which will thus ensure legal certainty in that domain independently of a potential opt-out.
Moreover, it is important to note that the same is true with prior uses of an invention patented through a European Patent with Unitary Effect. In fact, following article 2 of the UPCA “patent” refers to both a European patent and a European Patent with unitary effect.
Now an uncertainty remains for the qualification of infringement acts that occurred prior to and after the opt-out. Indeed, although the definition of the infringement acts under the UPCA (article 25 and 26 UPCA) is very similar to that of the national laws of the Contracting States (eg article L. 613-3 French IP Code), it is not identical and national case law differs from one country to another. The uncertainty stands from the fact that pending the opt-out the alleged infringers should assess their risk by reference to the applicable provisions of the UPCA taking into consideration the fact that if they were to sue for infringement this would occur before the UPC and not before the national courts. In the event the patentee decides an opt-out than the alleged infringer’s assessment of his risk is flawed.
This risk is inherent to the opt-out possibility that the Contracting States have decided to offer to EP holders. One issue which does not seem to have been contemplated however is whether the national courts which would have to rule on the infringement of an opted-out patent would have to apply the UPCA rules for the period of time prior to the opt-out and the national rules for the infringement acts that occurred after the opt-out. For instance, the statute of limitation might differ (eg, Austria infringement claims must be brought within three years from the date the right holder obtains knowledge of both the infringement and the identity of the infringer whereas the UPCA states at article 72 that “(…) actions relating to all forms of financial compensation may not be brought more than five years after the date on which the applicant became aware of the last fact justifying the action.”). This subject will however be treated in more depth in a later post, soon to be published.
