Managing IP Names WilmerHale as US Patent Contentious Firm of the Year for the Northeast Region


WilmerHale Recognized by LMG Life Sciences at Annual Awards



  • Achieved a trial victory for Apple marking a significant milestone in the company’s seven-year fight to hold Samsung Electronics accountable for copying the original iPhone and applying patented Apple designs and features to numerous Samsung phones. After four days of deliberation, a jury awarded $539 million in damages to Apple. Apple and Samsung later announced a settlement of all remaining patent litigation between them.
  • Prevailed at the ITC, the U.S. district court, and then twice before the Federal Circuit on behalf of Intel, Apple, and Hewlett-Packard after X2Y Attenuators LLC claimed that Intel’s microprocessors, and the Apple and HP computers containing them, infringed multiple X2Y patents. 
  • Won a major, complete victory for Bristol-Myers Squibb and Pfizer in one of the largest Hatch-Waxman cases ever filed. A district judge found the patents covering our clients’ blockbuster drug Eliquis® were valid and infringed by all generics challenging them. This case covered 25 generic companies and likely protects Eliquis® until at least 2031. 
  • Earned a milestone victory for Becton Dickinson (BD) that ended an eight-year multinational patent infringement dispute with Braun Melsungen in US district court, the Federal Circuit, the PTAB and numerous jurisdictions across the globe. Eleven patents were asserted against BD in the US, and more than 60 patents in a half dozen countries were asserted outside the US. Braun ultimately settled the global dispute and gave BD a broad portfolio license.
  • Prevailed on behalf of Swatch Group Ltd. in a counterfeiting case against a Canal Street landlord after being brought on as counsel days before trial. Following a one-week trial, a jury unanimously found the landlord liable for contributory trademark infringement. The jury further awarded $1.1 million in damages based on the sale of a single counterfeit Omega.
  • Obtained a full defense verdict for Bombardier Recreational Products (BRP) defeating a $130 million trademark infringement claim brought by Jaguar Land Rover. Following an eight-day trial with 19 witnesses, the jury rendered a 7-1 verdict in BRP’s favor, finding that BRP’s Can-Am Defender off-road vehicle did not infringe Land Rover’s trademark for DEFENDER. 
  • Achieved a noteworthy victory for Takeda's wholly owned subsidiary, Millennium Pharmaceuticals, at the Federal Circuit when the appeals court reversed a district court finding of patent invalidity based on obviousness and remanded the case with instructions to enter judgment in favor of Takeda. This Hatch-Waxman matter involved a patent owned by the US government and exclusively licensed to Takeda covering the latter’s blockbuster oncology drug Velcade® which has annual US sales in excess of $1 billion. 
  • Earned a major win for Ancestry when a district court judge granted our motion to dismiss finding that all patent claims asserted by 23andMe were invalid because they were directed to patent ineligible subject matter. This case was the first major legal clash between the two top genetic testing companies in the country, and upon appeal to the Federal Circuit, the panel unanimously affirmed the district court’s decision.
