Clients Japanese wire manufacturer and its U.S. subsidiary

Jones Day secured a final judgment of non-infringement and invalidity in favor of a Japanese wire manufacturer and its U.S. subsidiary in a patent infringement case related to coil wire technology in the Central District of California. In addition, Jones Day successfully instituted an inter partes review (IPR) of the asserted patent, and the United States Patent Trial and Appeal Board (PTAB) ultimately found all claims of the asserted patent unpatentable on three separate grounds—two grounds of anticipation and one ground of obviousness. After the opposing side appealed the PTAB's decision to the Federal Circuit, Jones Day secured an affirmance within three court days following oral argument.
