Appellate and IP Teams Secure Important Federal Circuit Patent Win for Donghee America


Backing our Supreme Court and Appellate and IP teams, the Federal Circuit this week rejected patent infringement claims against Donghee America in a case related to the manufacture of plastic fuel tanks through blow molding. The ruling upheld a lower court decision granting summary judgment to Donghee after finding its products do not infringe two patents of competitor Plastic Omnium for making plastic fuel tanks.

The published opinion found Donghee’s argument for non-infringement “was consistent with (the court’s) claim construction order based on undisputed differences between the asserted patents and the accused product.”

This is the latest win for Donghee in the litigation. A trial team led by partner Alyssa Caridis knocked out many of the patent infringement claims during the summary judgment stage, leading to the appeal of two contested claims in the Federal Circuit. Partner Eric Shumsky, who argued the case in the Federal Circuit, led the appellate effort.

In addition to Eric and Alyssa, the trial and appellate team included Mel Bostwick, Ned Hirschfeld, Jeremy Peterman, Vickie Feeman, Claudia Frost, Andrew Kim, Amy Maruska and former associate Nick Lam.
