Kumho Petrochemical

We defended Kumho Petrochemical in a complex patent litigation matter brought by Flexsys before the International Trade Commission. The investigation, a 337 Action, involved a patent alleged to cover the process used by Kumho Petrochemical and its supplier, Sinorgchem, for making an antidegradent used in tires and other polymer products. While our firm was conflicted from the matter as a result of a new defense raised by the respondents shortly before the close of discovery, one of the defenses that we developed for Kumho Petrochemical was ultimately successful before the ITC.
