About William
William Nelson earned his J.D. from San Joaquin College of Law in 2011. He went to law school after an earlier period of study, and he entered the legal profession determined to work at the intersection of technology and law. The degree set the stage for a career centered on intellectual property and related disciplines.
He is admitted to practice in California and is a registered patent lawyer with the United States Patent and Trademark Office. That registration allows him to represent inventors before the USPTO on patent prosecution and related patent matters. He joined several professional organizations early in his career and has maintained active memberships in those groups for years.
Nelson belongs to a number of bar and industry associations. He has been a member of the American Intellectual Property Law Association and the American Bar Association’s Intellectual Property Law Section since 2014. He also holds membership in the California Lawyers Association’s Intellectual Property Law Section, the California Lawyers Association’s Antitrust, Unfair Competition, and Privacy Law Section since 2018, and the Fresno County Bar Association. Those memberships place him in regular contact with lawyers who handle patents, trademarks, privacy issues and competition matters.
He works at Sierra IP Law, PC. At the firm he prepares and prosecutes patent applications, assists clients with trademark filings, and provides counseling on intellectual property strategy. His registration before the USPTO is central to the patent work he accepts. He represents individual inventors and small businesses as they move from concept to protected intellectual property, and he coordinates filings that align patent claims with client business objectives.
Nelson’s practice also touches on areas where intellectual property and commercial law meet. He engages with questions of unfair competition and privacy that often arise in technology-driven disputes. His association memberships reflect that broader interest. He participates in local and national conversations about how IP law adapts to new technologies and business models.
Colleagues describe him as practical and detail-oriented in technical filings. He keeps current through professional group meetings and industry publications. In private practice at Sierra IP Law, PC he continues to advise clients on patent prosecution, trademark matters, and related intellectual property issues.
