Jill M. Browning joined the firm in 1996 and became the first woman partner in 2001.  She is currently a managing partner of G&B and a co-chair of the litigation group, focusing on Contested Matters before the U.S. Patent and Trademark Office (AIA proceedings as well as interferences and ex parte reexaminations) and district court litigation.

Jill has significant experience representing clients in all phases of patent disputes, and understands the importance of thinking outside the box to find common ground and reach amicable solutions to disputes when possible.  And, when that is not possible, Jill is comfortable advancing the case to trial, whether before the PTAB, a judge or a jury.

She routinely represents patent owners or petitioners before the PTAB or in district court, and also advises clients on international portfolios and due diligence matters.  Jill has considerable experience in counseling clients with respect to FTO opinions, based on infringement and/or validity, as well as counseling clients with respect to patentability analysis and preparing license and collaboration agreements.

Jill is also the head of the Trademark Department and handles district court trademark actions as well as oversees the trademark prosecution and opposition practice.

Before joining the firm, Jill was a law clerk with the Eastern District of Virginia (the “Rocket Docket”).
