Protective letters in the UPC

Protective letter

At least if the current plan holds, the Unified Patent Court will quite soon be up and running. Businesses express concerns on possible misuse of the UPC’s powerful measures for patent enforcement such as pan-European injunctions and Saisie, i.e., an order to compulsorily preserve evidence on alleged infringers’ premises. Along with these measures, however, the UPC will also provide tools aimed exactly at preventing the misuse of such orders. A so called “protective letter” will be one of the tools to that end. This tool may be unfamiliar to many readers from outside Germany, since it is mainly a German peculiarity and although available in several other European jurisdictions, such as Switzerland, the Netherlands and Belgium, it has limited practical importance there. Now, being introduced by the UPC agreement, the protective letter is expected to gain its influence throughout Europe.

If you are sued by a patentee for patent infringement, one of the options you often have would be to attempt to invalidate the patent on the ground that the patent lacks patentability. The issue here is whether you can assert invalidity of the patent at issue to an infringement court, or you need to initiate a separate proceeding at a national patent office or a specialized patent court in order to argue patent invalidity. As for Japan, in addition to an invalidation proceeding at the Japanese Patent Office (Track 1), Japanese patent law allows a defendant in an infringement court to assert patent invalidity within the same proceeding (invalidity defense), and the court can judge the validity on its own (Track 2). This legal system can be referred to as a “double track system”.  Examples of jurisdictions with this system besides Japan are the U.S., the U.K., France and Korea.
