We support our life sciences clients' business objectives by providing a comprehensive range of services, including:

  • worldwide protection of IP rights;
  • patent infringement litigation, including Hatch-Waxman (ANDA) and Biologics Price Competition and Innovation Act (BPCIA) litigation;
  • resolution of licensing disputes, including litigation, arbitration and mediation;
  • strategic patent portfolio development and life-cycle management; 
  • Patent Term Extension and Orange Book Listing counseling;
  • landscape, freedom-to-operate, patentability, validity and infringement opinions; 
  • IP diligence in connection with public and private offerings and mergers and acquisitions; and
  • the implementation of strategies using ex parte reexamination, inter partes review and post-grant review to challenge or defend issued patents.

Life sciences industry leaders turn to WilmerHale to resolve their most complex offensive and defensive intellectual property disputes, including Hatch-Waxman (ANDA) litigation and the emerging regulatory and litigation processes of the BPCIA. From conducting early assessments of clients' patent and product portfolios to representing clients in all phases of litigation, we understand the unique tactics and strategies implicated by life sciences litigation, and work with clients to implement an overarching strategy designed to protect their most valuable assets.

WilmerHale has a well-established track record of successfully representing innovator pharmaceutical companies in patent infringement litigation against generic companies that file ANDA and/or 505(b)(2) applications. We have extensive experience at all stages of this process, including reviewing patent portfolios and providing strategic advice in advance of any generic filing, reviewing ANDA and 505(b)(2) applications, handling disputes involving multiple patents and numerous generic defendants, litigating patent infringement matters through trial in the district courts and appeals at the Federal Circuit, and achieving resolution of appropriate matters through settlement. In the last five years, we have handled more than 50 ANDA matters, including litigation in district courts and at the Federal Circuit, and have taken some matters to trial.

WilmerHale has served as national trial and appellate counsel in multi-jurisdictional patent infringement actions and has successfully represented life sciences clients before the International Trade Commission, district courts throughout the United States, the Federal Circuit and the US Supreme Court. By combining our trial and appellate strengths to shape litigation strategy from the outset, we are able to maximize the likelihood of success for our clients.
