Intellectual Property


David MacDonald focuses on intellectual property, pharmaceutical and technology transactions, including joint ventures, consortiums and strategic alliances. He regularly advises pharmaceutical and biotechnology clients on transactional matters, including licensing, marketing and co-promotion, supply and distribution, and other collaboration arrangements. He advises global technology companies on patent strategies, patent and software licensing (including settlement of patent litigation), and monetization (assertion, securitizations, trusts and investment funds). David also advises clients on the intellectual property issues that arise in mergers, acquisitions, divestitures, recapitalizations and bankruptcies. Since 2010, David has been included in Intellectual Asset Management magazine’s list of the world’s top 250 patent and technology licensing lawyers for his “cutting-edge expertise on how patent law issues complicate licensing deals” and his “impressive profile in IT outsourcing.” David has also been included in the IAM Patent 1000 since 2012, which describes him as “one of the pharmaceutical industry’s go-to deal brokers” and says he “manifests a rare faculty for facilitating complex collaborations and transactions between life sciences entities.” David was also highlighted in The Legal 500 United States 2012, 2015, 2017 and 2018 guides to leading U.S. law firms for business. David is the former Chair of the Transactions Involving IP Rights Committee of the ABA.

Lawyer Rankings

United States > Intellectual property > Patents: licensing

Kirkland & Ellis LLP acts for licensors and licensees alike, thereby offering clients experience in negotiating from both ends of the table. The practice regularly assists with joint development agreements, supply agreements and agreements pertaining to the provision of services and technical assistance. Another area of strength is the development and implementation of patent licensing programs, often by way of corporate transactions, such as joint ventures or divestitures, but also by way of securitisations, synthetic royalties, royalty buy-outs and royalty interests. The arrival of Shellie Weisfield Freedman from Gibson, Dunn & Crutcher LLP in January 2019 bolstered the group’s New York bench. Fellow New Yorker David MacDonald and the Chicago-based Seth TraxlerNeil Hirshman, Matthew Colman and Adam Petravicius are the other key contacts.
