Cullen Taylor helps life sciences companies structure and negotiate their most complex agreements, particularly those involving the development, acquisition, and commercialization of intellectual property and technology. Cullen takes a practical, results-oriented approach to transactions, drawing on his broad experience to anticipate and address problems before they arise.

Cullen understands the legal and commercial risks that arise as parties enter, live under, and exit long-term partnering arrangements. Cullen is skilled at structuring and drafting contracts that address these concerns while keeping the client's business goals at front and center.

Cullen handles a variety of transactions within the life sciences industry, including product acquisition, licensing, research and development, collaboration, co-promotion, supply, and distribution agreements. His clients include pharmaceutical and biotechnology companies and device and diagnostics manufacturers with products and therapies at all stages of development. Cullen is often called upon to advise such clients on discovering, developing, and acquiring cutting-edge therapies and innovative technologies.

Cullen is head of the firm's Life Sciences Licensing and Commercial Transactions team. He regularly collaborates with his colleagues in the firm's Corporate and Regulatory practices to address intellectual property and technology-related issues that arise in corporate transactions and in the product approval process, and has advised a number of clients on licensing matters in relation to the recently implemented Inflation Reduction Act.

Cullen was recognized by Managing IP as the 2021 IP Transactional Lawyer of the Year for the Americas.
