REPRESENTATIVE MATTERS
Home Semiconductor / ProMOS v. Samsung (District of Delaware)
Led patent holder Home Semiconductor / ProMOS's assertion campaign against Samsung, asserting semiconductor process and circuit technology across multiple litigations. After successfully defending key patents from inter parties review challenges at the PTAB and winning key claim constructions at Markman, the cases settled favorably, launching ProMOS’s successful licensing program.
Innovention Toys v. MGA Entertainment (Eastern District of Louisiana)
Won complete trial victory for Innovention by convincing jury that MGA intentionally plagiarized Innovention’s patented chess-like laser board game. Jury found liability and willful infringement and the judge awarded treble damages and attorneys fees. Later represented Innovention in the U.S. Supreme Court, which upheld all aspects of Innovention’s victory.
​
Florida Atlantic Univ. Research Corp. v. Acer Inc. and Acer America Corp. (Southern District of Florida)
Defended Acer from charges that its computer products infringed patents covering video display technology. Won summary judgment invalidating the asserted patents, a total defense victory. Decision affirmed by the Federal Circuit.
​
Phoenix Digital Solutions v. HTC (Northern District of California)

​
Angioscore v. TriReme Medical (Northern District of California)
Defended TriReme Medical from Angioscore’s claims that its products infringed a patent for angioplasty catheters. Won complete trial victory. Jury found not only that TriReme did not infringe, but that the asserted patent was also invalid.

Defended Xiamen Kingdomway Group Co. (XKGC) against accusations that it infringed Kaneka’s patent for the production of the dietary supplement CoQ-10.

The ITC initially ruled against Crocs on its two patents (one patent not infringed; the other invalid). Led appeal to the Federal Circuit and obtained a complete reversal on both patents, resulting in a total victory for Crocs. The Commision then entered a general exclusion order that barred the importation of all infringing knock-off shoes.
