Jason’s notable experience includes his representation of:

Defeated a summary judgment motion of invalidity brought by LG by persuading the court to apply a novel theory of IPR estoppel. Presented and won arguments at a Markman claim construction hearing and secured reconsideration on the issue of pre-suit damages.
  • A mobile payment company that holds over 60 patents in IPRs filed by Samsung against eight patents in the mobile payment and non-browser-based app space. Filed Patent Owner Preliminary Responses in each IPR, and the PTAB agreed and declined to institute any of the IPRs on the merits. In related district court action, defeated Samsung’s efforts to hold the patents ineligible under Section 101.
  • Ayla, a San Francisco-based cosmetics and beauty boutique, in winning a landmark decision in the Ninth Circuit on the issue of personal jurisdiction over foreign companies.*
  • Jeffrey Sedlik, a world-renowned, award-winning professional photographer, in a case involving the unlicensed use of his copyrighted photographic portrait of world-famous jazz musician Miles Davis by tattooist Kat Von D of “Miami Ink” and “LA Ink.” Glaser Weil successfully convinced the court to grant reconsideration and hold that the tattoo inked by Von D did not make transformative use of Sedlik’s photograph of Davis.
  • Michael Gaffney, Muhammad Ali’s personal photographer, as the plaintiff in a copyright infringement case against Authentic Brands Group LLC.
  • StemExpress, a life sciences company, against a former sales employee and her new employer, who were accused of committing trade secret misappropriation.
