International Trade Commission

  • Collapsible and Portable Furniture - Gary is currently leading a team representing complainant GCI Outdoor in a case asserting two patents relating to portable backpack chairs. One set of respondents entered into a consent order, and the case is scheduled to go to trial against three other respondent groups later this year.
  • Human Milk Oligosaccharides and Methods of Producing the Same - Gary is lead counsel for Jennewein Biotechnologie GmbH in a case involving genetically engineered E. coli used to make 2’-FL, a human milk oligosaccharide sold by Jennewein to Abbott for use in its leading infant formula, Similac. After vigorous opposition from the complainant, in May 2020, the full Commission reversed the ALJ and found that Jennewein’s alternative process was properly in the case and that the process did not infringe, and specifically carved that process out from its exclusion order, enabling Jennewein to continue to supply its customers in the US market.
