Representative Experience

  • Represented YouTube and its CEO, Susan Wojcicki in a rare dismissal of trademark infringement and false-advertising claims with prejudice at the pleading stage. The court agreed that user-generated content posted on YouTube does not constitute “use in commerce” for purposes of trademark law or “commercial speech” for purposes of false advertising. The court also agreed that, in light of Tiffany v. eBay, YouTube cannot be held liable for indirect trademark infringement based on user-generated content (Lops v. YouTube et al., (USDC D Conn 2022)).
  • Represented Nespresso USA in a trademark and trade dress infringement action under the Lanham Act against Peet’s Coffee, Inc., which offered "Nespresso Compatible" capsules for use with Nespresso's machines. The case resulted in a favorable settlement after the Hon. Colleen McMahon complimented Nespresso’s Complaint by noting “the court (which has seen quite a few trade dress cases) has seldom seen a better crafted pleading.” (Nespresso USA, Inc. v. Peet’s Coffee, Inc., (USDC SDNY 2021)).
  • Represents Blue Bottle Coffee, LLC in a trademark and trade dress infringement action (Blue Bottle Coffee, LLC v. Southern Technologies, LLC, (USDC ND Cal 2021)).
