Filing a trademark, prosecuting a patent, or defending an inter partes review at the USPTO? Washington has the densest concentration of IP counsel in the country: the USPTO sits across the river in Alexandria, the Federal Circuit (which hears every US patent appeal) is downtown, and the TTAB rules on every contested trademark from the same neighborhood. The firms below file at USPTO every week and try patent cases before the Federal Circuit.
You launched a product and a competitor used your brand name on Amazon last week. You filed your trademark application pro se and got a 2(d) refusal you do not understand. You received a cease-and-desist letter alleging patent infringement and the threatened damages exceed your annual revenue. You are about to raise a Series A and your VC wants confirmation that the IP is clean. Each of these calls for different IP work, and DC counsel handles all of it.
Washington's special role in US IP law comes from geography: the United States Patent and Trademark Office is headquartered in Alexandria, Virginia, a short Metro ride from downtown DC. The Trademark Trial and Appeal Board (TTAB) and Patent Trial and Appeal Board (PTAB) sit at USPTO. The US Court of Appeals for the Federal Circuit (which hears every patent appeal, every TTAB appeal, and a slice of trademark appeals) sits at 717 Madison Place NW in DC. The result: most large IP-heavy companies (pharma, biotech, software, semiconductor, brand-heavy CPG) keep DC counsel on retainer for prosecution and PTAB work even when their general litigation counsel is somewhere else.
For DC-area businesses, the practical implication is that you have direct access to the deepest IP bench in the country. Boutique IP firms like Sterne Kessler and Jordan IP Law focus entirely on patents and trademarks. Full-service AmLaw 50 firms like Covington & Burling, Steptoe, and Arnold & Porter have IP litigation groups that handle Federal Circuit appeals routinely. Fish & Richardson, a national IP-only firm, has its DC office one Metro stop from USPTO. The right fit depends on what you need: a flat-fee trademark filing, a multi-year patent prosecution program, PTAB defense against an aggressor, or bet-the-company patent litigation in the Eastern District of Texas.
