Robert Bosch GmbH filed an infringement action against Grizzly Tools and three Lidl entities concerning European Patent EP 3 030 383 B1, asserting infringement in Germany, Spain, France, Great Britain, Italy, and Poland.

Bruker Spatial Biology, Inc., Luxendo GmbH, Bruker Nederland B.V. v.10x Genomics, Inc., President and Fellows of Harvard College

The Court of Appeal of the Unified Patent Court rejected Bruker's appeal challenging the Munich Local Division's decision to reimburse only 60% of the court fees paid for Bruker's application for compensation under Rule 213.2 RoP. The court held that a request to lay open books for the purpose of determining compensation under Rule 213.2 RoP forms part of the separate procedure for the determination of damages governed by Chapter 4 of Part 1 RoP, requiring payment of both a fixed fee and a value-based fee. The court further found that combining a request to establish liability with a request to lay open books does not entitle the applicant to a reduced or no fee.
