Zachariah Summers

Zachariah Summers is a partner in the Los Angeles office of Quinn Emanuel Urquhart & Sullivan, LLP, specializing in complex patent litigation with a focus on technology-related trials. He previously worked in Quinn Emanuel's New York office before re-joining the firm in 2018 after a period as a Senior Legal Editor at Practical Law.

His practice encompasses a broad range of technologies, including life sciences (biotechnology, CRISPR-Cas9, surgical prep products), semiconductors, LED technology, and smartphone and wireless technologies. Summers primarily represents defendants, including major operating companies such as the Broad Institute, Halozyme Therapeutics, Qualcomm, Samsung, MediaTek, Google, VIZIO, Motorola, Cree, and Everlight Electronics. His tracked appearances align with this, showing two defendant-side roles.

Summers has been involved in several high-profile matters and achieved notable outcomes. He successfully defended the Broad Institute's foundational CRISPR-Cas9 patents in interference proceedings before the Patent Trial and Appeal Board (PTAB), a role that earned him "Litigator of the Week" recognition. He also secured a complete victory on summary judgment and appellate affirmation for VIZIO in patent infringement cases and successfully defended Samsung against Apple in a follow-up patent infringement trial and appeal. His experience also includes successfully defending MediaTek at the International Trade Commission (ITC) and invalidating asserted claims for Everlight in a jury trial. He has experience in IPR proceedings, representing clients like Bard Dickinson. His tracked case, Unified Patents v. Halozyme Inc, involves patent challenges, consistent with his PTAB experience.

Summers earned his J.D. from Yale Law School in 2007 and a B.A. summa cum laude from Illinois Wesleyan University in 2003. He is admitted to practice in California and New York.
