- Certain Video Processing Devices, Components Thereof, and Digital Smart Televisions Containing the Same (337-TA-1222) – Represented DivX, a video codec company headquartered in San Diego, in enforcing patents before the ITC in the District of Delaware. The asserted patents involve innovations relating to digital rights management and streaming media. LG and Samsung settled after the Markman order was issued, leaving TCL as the sole remaining respondent. Shortly after the seven day evidentiary hearing held in July 2021, one of the two principal suppliers of the accused streaming technology to TCL, namely Roku, stepped in and took a license to DivX’s portfolio, thus partially resolving DivX’s claims against TCL. Prior to the court issuing a decision on the merits, DivX and TCL entered into a bilateral settlement agreement resolving DivX’s remaining claims against TCl and bringing an end to all pending litigation.
- Certain Semiconductor Devices, Products Containing the Same, and Components Thereof (II) (337-TA-1177) - Represented GlobalFoundries at the International Trade Commission and in multiple Western District of Texas actions, involving the direct and indirect infringement of four patents related to semiconductor devices, integrated circuits, and products containing the same.

Following oral hearing in May 2019, the Administrative Law Judge issued an Initial Determination finding that Jennewein had infringed claims of Glycosyn’s patent and recommended that a limited exclusion order issue, including a certification provision with heightened requirement.
