CASTELLANO is a Washington, D.C.-based intellectual property law firm specializing in patents, trademarks, IP litigation, IPRs, and Federal Circuit appeals.  We are experienced trial lawyers actively litigating cases in federal courts nationwide, the International Trade Commission, the Federal Circuit, and in IPRs at the USPTO Patent Trial and Appeal Board.  

We are registered patent attorneys and experts in counseling and representing inventors and patent applicants in patent application examination proceedings and appeals at the USPTO.  Our patent and trademark preparation and prosecution practice serves the needs of small businesses, universities, and larger businesses alike.  We handle inbound patent work for numerous law firms around the world some of which have been clients for over a decade.

Our attorneys are former USPTO examiners, former large law firm practice leaders and partners, and have a wide range of technical and industry expertise.  We leverage this background in a small firm setting to offer high quality service and attention to detail with flexible and reasonable fee arrangement alternatives that suit individual client needs.
