Work highlights

Obtained a Federal Circuit victory for Taction Technology in its patent suit against Apple over iPhone and Apple Watch vibration technology, successfully convincing the appeals court that the district court abused its discretion in excluding expert opinions and erred in claim construction.
Won a comprehensive ITC victory for JUUL Labs, securing a sweeping exclusion order after proving NJOY infringed four JUUL patents—an especially significant result in a forum where respondents often prevail and one that delivers JUUL a major competitive advantage in the vaping industry.
