Katherine Dominguez

Katherine Dominguez is a partner and co-chair of the Intellectual Property Practice Group in the New York office of Gibson, Dunn & Crutcher LLP. Her practice focuses on complex patent litigation, handling cases from discovery through trial and appeal, including before the Federal Circuit.

Ms. Dominguez demonstrates a broad technological expertise, encompassing both high-tech and life sciences matters. In high-tech, her experience covers systems and software for data storage, encryption, interactive television, intrusion detection, mobile communications, network authentication, and wireless networking. Her life sciences work has involved recombinant DNA, pharmaceutical composition and dosing, and medical devices. Her tracked appearances consistently place her on the defendant side, aligning with her notable success in defending operating companies.

A significant outcome in her career includes securing a complete defense verdict of non-infringement on 30 claims for T-Mobile in a jury trial against Prism Technologies in the District of Nebraska. This verdict was subsequently affirmed by the Federal Circuit, which also invalidated the asserted patents on Section 101 grounds. Ms. Dominguez also represented T-Mobile USA, Inc. as a defendant in Headwater Research LLC v. T-Mobile USA, Inc. et al. More recently, she appeared for defendants ByteDance Ltd. et al. in DiStefano Website Innovations, LLC v. Bytedance Ltd et al., a case involving patents related to webpage creation, e-commerce tooling, and hyperlinking systems. While her primary work highlighted appears to be defense-oriented, she has also obtained an eight-figure damages award for a patentee client in the network storage equipment sector.
