Andrew Colin Mayo

Andrew Colin Mayo is a patent litigation attorney and a Director at Ashby & Geddes, P.A. in Wilmington, Delaware, where he focuses his practice on intellectual property disputes. His firm's intellectual property group handles patent, trademark, false advertising, and unfair competition cases across various industrial sectors, including pharmaceuticals, telecommunications, electronics, computer hardware and software, internet technologies, biotechnology, medical devices, chemicals, and automotive matters. Mayo has been recognized as a "Leading Individual" in Intellectual Property by Chambers USA since at least 2023, with clients noting his "depth of insight into the space that is exceptional" and describing him as an "excellent lawyer."

Mayo's tracked appearances consistently show him representing defendants. In all four recorded cases, he served as counsel or local counsel for defendants, indicating a primary focus on defending companies against patent infringement allegations. The firm itself serves clients on both the plaintiff and defense side of intellectual property litigation, but Mayo's personal record reflects a defense-oriented practice.

His notable cases include defending Google LLC in Google LLC v. Accusearch Technologies LLC, a litigation initiated in 2025 concerning annotated internet search results and Google's search engine products and services. He also represented defendants in Realtime Data LLC v. Array Networks Inc. et al. and Realtime Data LLC v. Reduxio Systems, Inc. et al. These cases involved patents related to digital data compression and acceleration technologies. While the Realtime Data litigation saw some patents initially dismissed under Section 101 and later affirmed by the Federal Circuit in related appeals, no specific trial verdicts directly attributable to Mayo for these cases are publicly detailed. While some of the patent owners in his cases are involved in PTAB proceedings (e.g., Google initiating IPRs against Accusearch patents), specific information on Andrew Mayo's direct appearances in IPR or PGR proceedings is not readily available.

Andrew Mayo earned his Juris Doctor (J.D.) from the University of Florida Levin College of Law in 2007 and was admitted to the Delaware bar in 2008.
