WilmerHale Receives Six Practice and 21 Individual Recognitions in IAM Patent 1000 2018


WilmerHale Honored Throughout 2019 U.S. News - Best Lawyers® Best Law Firms List



  • Successfully represented Aegerion (alongside co-counsel) in two inter partes reviews challenging patents covering the approved dosing methods of Juxtapid, a lipid-lowering agent for the treatment of familial hypercholesterolemia.

  • Achieved a victory for patent owner Akamai Technologies against Limelight Networks when the Patent Trial and Appeal Board issued a final written decision finding all instituted claims not invalid.
  • Successfully invalidated all 371 claims of 10 patents asserted against a major consumer products company (later affirmed by the Federal Circuit) in one of the largest inter partes review proceedings ever brought. 

  • On behalf of Unified Patents, achieved a significant victory when the Patent Trial and Appeal Board issued its final written decision invalidating all claims against a patent, assigned to Nonend Inventions N.V., which Nonend asserted in multiple district court cases against a wide range of companies.
  • Also for Unified Patents, used the inter partes review process to successfully challenge all 16 claims of a patent held by Sportbrain Holdings, which had been asserted against more than 140 defendants.

  • Achieved a series of victories, culminating in four successful covered business method reviews, in which the Patent Trial and Appeal Board invalidated 83 of a patent assertion entity’s claims against a group of major financial institutions.
  • For electronic wheelchair developer Permobil, achieved a victory when the Patent Trial and Appeal Board issued final written decisions on two inter partes reviews that declared all challenged claims unpatentable. WilmerHale also successfully convinced the US Court of Appeals for the Federal Circuit to uphold the decisions after the patent owner appealed.

  • Successfully invalidated a patent through an inter partes review on behalf of Becton Dickinson, challenging a patent relating to needle technology. BD filed the proceeding after it was sued for infringement. We obtained a final written decision canceling all the challenged claims, and the litigation subsequently settled on terms favorable to BD during the Federal Circuit appeal.
  • For a Fortune 500 technology company, obtained a significant victory when the Federal Circuit held that three patent claims that we had challenged in an inter partes review adverse to an acoustics company were unpatentable. The patents related to speaker designs that the acoustics company accused our client of infringing.
  • Represented VMware and EMC in a suit, initially filed in the Eastern District of Texas, relating to cloud computing. The plaintiff, a non-practicing entity, alleged infringement of a portfolio of patents by most of the major cloud computing companies. VMware and EMC were the only companies in the first round of defendants to file inter partes reviews. We ultimately convinced the Eastern District of Texas to transfer the case to California, and convinced the Northern District of California to stay the case pending the proceedings. The Patent Trial and Appeal Board subsequently invalidated all challenged claims, and the Federal Circuit affirmed.
