In addition to services related to all aspects of patent, trademark, and copyright law, including counseling, prosecution, licensing, and litigation, Finnegan provides counseling and litigation services in advertising, privacy, and a wide spectrum of additional IP-adjacent commercial matters, including trade secrets, international trade, the Internet, e-commerce, government contracts, antitrust, and unfair competition. A comprehensive approach to clients’ IP needs and Finnegan’s global scale underpins its year-to-year, decade-to-decade preeminence in IP litigation across all industries and tribunals.

Finnegan offers full-service IP legal and technical experience in virtually every industry and technology: biotechnology, pharmaceuticals, biologics and biosimilars, combination products, chemicals, electronics, semiconductors, computers and software, FinTech, blockchain, Internet of Things (IoT), automotive, aerospace and aviation, industrial manufacturing, consumer products, food and beverage, outdoor recreation, sports and fitness, digital health, medical devices, clean energy and renewables, robotics, textiles, artificial intelligence (AI) and machine learning (ML), and 3D printing.

With Finnegan’s practice centered on intellectual property, the firm creates economies of scale, focusing all resources on providing the best tools and teams for clients. The firm’s team is comprised of over 250[RA1] [DA2] litigators, including career trial attorneys. Approximately 300 of Finnegan’s legal professionals hold degrees in scientific disciplines (70+ hold PhDs), and the majority are also registered to practice before the U.S. Patent and Trademark Office (USPTO), European Patent Office (EPO), the German Patent and Trade Mark Office (DPMA), the UK Intellectual Property Office (UKIPO), or the European Union Intellectual Property Office (EUIPO). With more than 55 years’ IP experience, Finnegan handles hundreds of cases and proceedings across IP-related venues, including district courts, the U.S. International Trade Commission (ITC), the USPTO’s Patent Trial and Appeal Board (PTAB), U.S. Court of Appeals for the Federal Circuit and the U.S. 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. 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 patent and trademark 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 more than 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, proceedings at the USPTO, and ITC investigations.
