VirnetX Patents Again Held Invalid by PTAB
Mike Kasdan, together with James Bailey of The Law Firm of James T Bailey, represented The Mangrove Partners Fund before the U.S. Patent Office in Inter-partes Review Proceedings (IPRs) brought to challenge the validity of certain Virnetx Patents that are the subject of ongoing litigation against Apple, where Virnetx is seeking $700M in damages. The PTAB originally ruled in favor of Mangrove’s petitions, finding the challenged VirnetX claims to be invalid. After VirnetX appealed to the Federal Circuit and the Federal Circuit remanded, the PTAB recently affirmed their invalidity decision on these Virnetx Patents.
