Ansel Halliburton advises startups, growing companies, and entrepreneurs on IP strategy, data privacy and security, export controls, and corporate and securities law issues. Ansel has helped clients negotiate and close investment rounds, acquisitions, major sales contracts, licensing deals, and partnerships. Ansel also helps clients register copyrights and trademarks in the online and digital technology realms.
Well-versed in all aspects of litigation, Ansel manages complex intellectual property and fraud cases from inception through trial proceedings and to final judgments in state and federal courts. Ansel has won several cases resulting in verdicts in excess of $1 million. His cases have tested the boundaries of the law on electronic signatures and the interpretation of open source software licenses.
A programmer since age 10, Ansel stands at the crossroads of technology and the law, uniting the two disciplines through his personal and professional experience. Ansel initially worked as a software engineer for mobile technology and information retrieval startups before entering the legal field. As the first engineer with the Stanford Intellectual Property Litigation Clearinghouse — a pioneering legal analytics project later spun off as leading legal technology startup Lex Machina (acquired by LexisNexis) — he created specialized web crawlers and an open source rules engine that powered the most comprehensive IP litigation database and analytics tool.
The best results come from a deep understanding of both the law and technology.
Ansel leverages this unique background in advising clients regarding open source software licensing and cryptography export controls. Having received training on Black Duck Software’s open source and export compliance tools, Ansel is a Black Duck Certified Legal Professional.
Ansel earned a Bachelor’s degree from the University of California, Berkeley, where he was a founding member of the Berkley Political Review. He later completed his Juris Doctor at the UC Davis School of Law, where he won a Witkin Award for Academic Achievement in Trademark Law, contributed to both the UC Davis Business Law Journal and UC Davis Journal of International Law & Policy, and represented domestic violence and sexual assault survivors in a legal clinic.
Ansel's achievements have been recognized in his selection to the Daily Journal's 2016 "Top 40 Under 40" list, and as a Northern California Super Lawyers "Rising Star" in 2014, 2015, and 2017.
Before joining Kronenberger Rosenfeld, Ansel founded Halliburton Legal, a law firm dedicated to serving Silicon Valley technology startups, and was an associate at an IP litigation law firm before that. He is a member of the California Bar.
