notable
The Düsseldorf LD revoked Headwater's patent (claim 1) for added matter and dismissed the infringement action against Samsung. The claim featured determining whether an 'application' runs in background/foreground, but the parent application only disclosed determining whether a 'network service usage activity' runs in background/foreground — a material distinction. The court rejected the claimant's new argument at oral hearing under R.9.2 RoP: even though added matter was raised from the outset, new arguments based on completely different passages of a 200+ page document undermine the front-loaded procedure. All 26 auxiliary requests failed to cure the defect. The court left open whether a third-party defendant can bring Art. 138(1)(e) entitlement revocation.
