Due Diligence

Our IP due diligence practice draws on our experience handling a wide range of patent and transactional matters for our clients, and includes:

  • Performing due diligence evaluations of patent portfolios and related IP assets in the context of collaborations, licensing agreements, financings and mergers & acquisitions.
  • Advising some of the largest pharmaceutical and medical device companies in the world on freedom-to-operate issues and strategic patent portfolio development for their commercial products, in the United States, Europe and Asia.
  • Handling due diligence for many transactions on both the investor and target sides, including pre-IPO investments by venture capital groups, underwritten offerings of securities, pre-acquisition strategic investments by operating medical device companies and pharma-biotech collaborations.

Our diverse experience in patent and transactional matters uniquely positions us to assess strengths and weaknesses of target company’s IP positions, and translate those analyses into risk management strategies that benefit our clients' business interests. It also allows us to know which IP issues really matter in a deal, helping us to better focus client resources and energies.

Our patent attorneys also team with our FDA regulatory attorneys to advise on patent life cycle management, orange book listing and delisting matters , and issues relating to the follow-on biologics legislation.

  • Pre-litigation assessments
  • Orange book listing and delisting assessments
