Pierre Grosdidier worked as a consulting engineer for 18 years before becoming a lawyer. He now leverages his engineering, computer, and business background to litigate cases that involve complex technical and commercial disputes. In 2017, Pierre became Board Certified in Construction Law by the Texas Board of Legal Specialization.

With an engineering Ph.D. from Caltech, Pierre is at ease with the most complex technologies whether in the energy, construction, computer, manufacturing, or environmental industries. He has represented clients in lawsuits and arbitrations that arose from construction defects, industrial accidents, environmental contamination, oil and gas drilling operations, engineering services projects, computer and software projects, copyright and software copyright infringements, computer piracy, and trade secret thefts. Pierre’s litigation experience also includes claims under the Stored Communications Act and the Computer Fraud and Abuse Act, including one where the defendant planted a “time bomb” in his employer’s computer system. Pierre leverages his software and project management experience to efficiently organize and lead complex ESI preservation, collection, and review projects.

In accordance with Haynes and Boone’s tradition of leveraging capabilities and talent across-practice groups, Pierre works with the firm's Intellectual Property and Labor and Employment Practice Groups to help draft digital systems (e.g., computer, database, network, hand-held device, etc.) use agreements that reflect the latest legislation, case law, and litigation trends in this domain.

Pierre’s value to his clients lies in his ability to get past the core technical issues in order to focus on the legal merits of disputes. It also stems from his business perspective, having been responsible for projects, sales, business development, and operations at one time or another during his engineering career.

Pierre is a prolific legal writer, a practice he first developed as an engineer. Pierre is also firmly dedicated to the community, and has served on the board of directors and as treasurer of the Awty International School, the Lycée Français de Toronto, and a communal daycare in Bouc-Bel-Air, France. Pierre, a native French speaker, is an active member of the French-American Chamber of Commerce in Houston, currently co-chairs the committee to open a French-English immersion program in a Houston public school, and is involved in the Association of French Veterans in Texas. Pierre participates in the firm’s pro-bono activities and has helped an asylum applicant from Chad and a teen-age Central American refugee obtain permanent residency in the United States.
