Bill Blonigan is an associate in the Intellectual Property (IP) Practice Group in the firm’s San Diego (Del Mar) office.

Areas of Practice

Bill vigorously protects and defends his clients’ intellectual property rights in federal district courts, California Superior Court and the Court of Appeals for the Federal Circuit. He began defending his clients in U.S. courts in 2007. Bill particularly focuses on patent law, having practiced it since 2004 when he studied nights and weekends to pass the patent bar exam while working as an engineer for a startup medical device company developing electrical, software and biochemical solutions for diabetes patients. His practical experience with regard to developing products and his deep knowledge of intellectual property law helps him to creatively, efficiently and favorably resolve his clients' disputes through trial, appeal, mediation and licensing.

Bill litigates patent, copyright, trademark, trade dress, trade secret and contract disputes in California state court as well as federal district courts in California, Delaware, Illinois, Michigan, New York, North Carolina, Pennsylvania and Texas. He also helps clients build and maintain patent, trademark and copyright portfolios through the U.S. Patent and Trademark Office (USPTO) and the U.S. Copyright Office. During law school, he served as an extern law clerk to several USPTO administrative patent judges in Washington D.C., assisting with interferences and appeals in the electrical, chemical and mechanical arts.

Community and Professional Involvement

Bill is involved in his community as both a legal advisor and a business owner, which gives his law practice a practical and business perspective. He provides pro bono legal services on immigration and intellectual property matters. Since 2017, he has chaired the American Intellectual Property Law Association’s (AIPLA's) Model Patent Jury Instructions subcommittee, which provides model jury instructions for use by judges and litigants across the country. He has also served as an AIPLA Continuing Legal Education (CLE) Coordinator.
