Dianna El Hioum

Partner at Fox Rothschild LLP

Dianna G El Hioum is more than just a talented patent attorney.

Recently named chair of Fox Rothschild’s 100-plus-member national IP department, Ms El Hioum has a background in chemistry and biotechnology that helps her understand the development of drugs and medical devices – from early stage research to Food and Drug Administration approval, production and marketing. She also has extensive experience in the shooting sports industry.

Before graduating cum laude from Boston College Law School, she received a bachelor's degree in chemistry from the Massachusetts Institute of Technology. She also worked at an international biotechnology company involved in large-scale manufacturing of clinical and commercial drug products.

It is with that history that Ms El Hioum – who most recently served as chair of the firm’s patent practice group – has been able to develop valuable global patent portfolios for her clients, enabling them to expand their business around their intellectual property and to avoid and resolve disputes. A skilled negotiator and persuasive writer, she counsels clients on a variety of issues, including post-grant proceedings, drafting and negotiating licence agreements, dispute resolution, freedom-to-operate investigations and assessments of non-infringement, invalidity, patentability and enforceability issues.

For businesses, inventors and entrepreneurs in the shooting sports sector, Ms El Hioum delivers a rare combination of top-notch legal know-how and technical knowledge of guns and weaponry. The chair of her former firm’s shooting sports practice, she frequently handles IP matters for Fox Rothschild related to firearms, components, accessories and ammunition, including issues involving the US Department of Defence.

In 2020 Ms El Hioum, who is based in New York, helped secure a preliminary injunction that cleared the way for a Georgia company to retrieve equipment, parts and inventory from a Utah manufacturer that failed to produce a firearm that had been pre-ordered by nearly 700 customers.
