Magistrate Judge Sorokin denied Puma’s motion to compel supplementation of Nike’s preliminary infringement claim charts. Nike, which is asserting seven patents against seventeen Puma products, filed and then supplemented its preliminary infringement contentions pursuant to L.R. 16.6(d)(1)(A). The District of Massachusetts amended L.R. 16 in 2018 to require the patentee produce claim charts providing with as much specificity as reasonably possible a description of where and how each claim element is found in the accused products. Nike’s most recent supplementation, totaling 260 pages, contain full color photographs with annotations showing where each element is located on each accused product. Judge Sorokin found this sufficient at the early stage of the proceedings to meet the requirement of the amended rule.
