Finnegan, Henderson, Farabow, Garrett & Dunner, LLP is a true full-service IP firm with experts in every area of intellectual property and every technology. A comprehensive approach to clients’ IP needs and Finnegan’s mega-boutique size underpins its year-to-year, decade-to-decade preeminence in IP litigation across all industries and tribunals. From offices in the United States, Asia and Europe, Finnegan continues to be one of the world’s largest firms focusing on intellectual property, practising all aspects of patent, trademark, copyright and trade secret law, representing clients on IP issues relating to US and European patent and trademark law, international trade, portfolio management, the Internet, cybersecurity, e-commerce, government contracts, antitrust and unfair competition.

Finnegan offers full-service IP legal experience and technical expertise in virtually every industry and technology, including biotechnology, pharmaceuticals, biologics and biosimilars, chemicals, electronic devices and components, computers and software, financial services and business systems, artificial intelligence and machine learning, augmented reality (AR) and virtual reality (VR), digital health, nanotechnology, automotive, aerospace and aviation, industrial manufacturing, consumer products, media, food and beverage, hospitality, medical devices, clean energy and renewables, robotics, sports and fitness, textiles and three-dimensional printing.

With its practice centred on intellectual property, the firm is able to create economies of scale and focus all resources on providing the best tools, practices and procedures for clients’ IP matters. More than 300 of Finnegan’s legal professionals hold degrees in scientific disciplines (60+ hold PhDs), over 200 are registered to practise before the USPTO and more than 40 are former USPTO patent examiners. With more than 55 years’ IP experience, Finnegan handles hundreds of cases and proceedings across IP-related venues, including district courts, the US International Trade Commission (ITC), the USPTO’s Patent Trial and Appeal Board (PTAB), US Court of Appeals for the Federal Circuit and the US Supreme Court. As one of the first firms to file a petition and subsequently argue a post-grant review of a covered business method case following the implementation of the America Invents Act, Finnegan is one of the busiest law firms representing petitioners and patent owners in post-grant review proceedings, with more than 75 covered business method reviews, more than a dozen post-grant reviews (relatively few of which have been filed) and more than 800 inter partes review (IPR) proceedings. The firm files approximately 2,500 US and 1,000 foreign patent applications annually.

Surveys conducted by legal and business publications consistently rank Finnegan as one of the leading IP law practices in the world. The firm is ranked in the United States for contentious and prosecution trademark and patent work by publications including Managing Intellectual Property and The Legal 500, which have ranked Finnegan as a top-tier firm in nearly every significant IP category for over 10 years. The publications cite the firm’s winning record, technical expertise and deep bench of talent in all aspects of IP litigation, including trials, appeals and proceedings at the USPTO and ITC investigations.
