Publicly traded Xperi Corporation disclosed on October 11 that a German court has issued a tentative invalidity ruling against a semiconductor patent that the NPE has asserted against Broadcom and Avago. On October 5, the Federal Patent Court held that the patent at issue “may be invalid for various reasons” in a nullity, or invalidity, action filed by Avago (2 Ni 43/16), leading Xperi to delay the enforcement of an infringement ruling for that patent issued against Broadcom and Avago in March, with that litigation brought by several plaintiff entities under Xperi’s Tessera and Invensas brands. The same patent is also at issue in another Invensas lawsuit filed against Samsung on September 28. Meanwhile, available litigation records also indicate that nullity actions filed by Haier and ZTE are proceeding in a campaign waged by patent licensing firm Sisvel International S.A. over a portfolio of allegedly standard essential wireless patents, following a recent setback for the NPE in its parallel infringement suit against ZTE.
