For all we know it could have been...TPL/PTSC that went to the German Court...

1.At the Federal Patent Court, 56 legally qualified judges and 63 technically qualified judges serve alongside the court’s President and Vice-President (section 65 (2) of the German Patent Act). For patent proceedings, the composition of Federal Patent Court’s adjudicating bodies is regulated as follows:
The Technical Boards of Appeal, which are competent for adjudicating appeals against decisions by a patent examiner or an examining division at the German Patent and Trade Mark Office, are as a rule composed of one technically qualified judge as presiding judge, two additional technically qualified judges and a legally qualified judge (section 67 (1) of the German Patent Act).
The Revocation Boards, which are competent for adjudicating actions to revoke a patent, are as a rule composed of one legally qualified judge as presiding judge, an additional legally qualified judge and three technically qualified judges (section 67 (2) of the German Patent Act

There could have been a negative action by the German Patent and Trademark org. and .....WE...TPL/PTSC....took it to the Revocation Board body of the Federal Patent Court.
