Separation of proceedings in view of co-pending EPO proceedings

Case No. O2016_003 ¦ Order of 02 May 2016 ¦ “Prozessaufteilung”

Entities A and B (in a joinder of parties) have sued C for patent infringement. Four European patents are at stake (EP 000, EP 111, EP 222 and EP 333). A and B are exclusive licensees of the patents: Entity A is licensee of EP 000, EP 222 and EP 333; B is licensee of EP 111. The case has been separated in view of the different status of proceedings at the EPO (don’t be misled by the german term ‘Rechtsstand’ used in the decision; the formal status of all the patents is obviously granted): Opposition proceedings at the EPO have already been concluded for one of the patents (EP 000). For two other patents (EP 111 and EP 222), oral proceedings are scheduled for September and June 2016, respectively. The last patent in suit has only been granted in February 2016 and it is thus still open for opposition (EP 333).

  • The suit based on EP 000 (plaintiff A) will be continued under case ID O2016_003;
  • The suit based on EP 111 (plaintiff B) will be separately continued under case ID O2016_004;
  • The suit based on EP 222 and EP 333 (plaintiff A) will be separately continued under case ID O2016_005.

Another issue at stake is the choice of the language to be used by the parties. The plaintiffs used the English language and have submitted a letter allegedly confirming the agreement of the defendant with the use of the English language. However, the letter was apparently not issued by the defendant itself but a parent company. This letter was thus not considered as a consent of the defendant in accordance with Art. 36(3) PatCA; such consent is still outstanding.
