2025-08-20 - LD Mannheim - Centripetal v. Keysight Technologies

No further briefs allowed to introduce further new infringement readings after a new infringement reading had already been presented in the Reply.

The Mannheim LD panel confirmed the judge-rapporteur's order refusing Centripetal's application to submit a further written pleading containing a fifth infringement reading shortly before the oral hearing. The claimant had already presented four infringement readings (one in the Statement of Claim, three in the Reply) and the newly alleged functionality was known from ITC proceedings since 2023. The panel found that procedural fairness would require a defendant's response brief that could not be accommodated before the October hearing, and that claimant had had ample opportunity to present its case. Leave to appeal was denied as the question was case-specific.
