With offices in the United States, Asia and Europe, the firm practices European, German, UK, and US IP law. In addition 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 mega-boutique size underpins its year-to-year, decade-to-decade preeminence in IP litigation and trials across all industries and tribunals.

With Finnegan’s practice centered on intellectual property, the firm can create economies of scale and focus all resources on providing the best tools and teams for clients. Approximately 300 of Finnegan’s legal professionals hold degrees in scientific disciplines (75+ hold PhDs), and the majority are also registered to practise before the US 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 60 years’ IP experience, Finnegan’s global IP enforcement, litigation, and trials practice is comprised of over 250 litigators, including career trial attorneys. The firm handles hundreds of cases and proceedings across all forms of US IP litigation, German patent litigation, and European patent, trademark, copyright, and trade secret litigation in courts, including US 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, the US Supreme Court, German regional civil courts, UK courts, and the Unified Patent 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 patent office invalidity proceedings in the U.S. and Europe, including ex parte reexaminations, inter partes and post-grant reviews, nullity proceedings, oppositions, and third-party observations. The firm files approximately 2,500 US and 1,000 foreign patent applications annually.

Finnegan’s trademark practice, renowned for its experience, sophistication, creativity and depth, is comprehensive and follows the life of a mark from selection, clearance, prosecution and maintenance to portfolio management, trademark audits, licensing, watch disputes and litigation. The firm’s trademark clients include start-ups, small and medium-sized companies, as well as Fortune 100 companies. The range of industries represented includes sports and fitness, food and beverage, consumer products, mechanical, manufacturing, clean energy and renewables, entertainment, pharmaceuticals and biotechnology, financial services, publishing, the Internet, software, computers and telecommunications, and automotive.

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 litigation and non-contentious 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 nearly two decades. 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 global patent offices, and ITC investigations.

Kelly IP is an innovative boutique focused on all aspects of trademark, trade dress, copyright, design, domain name, and unfair competition law. The founding partners – Dave Kelly, Rob Litowitz, Linda McLeod, Lynn Jordan, and Stephanie Bald – all are recognised leaders in the trademark field and are known for their creative, practical, responsive, and cost-effective advice. They believe that brand owners deserve lawyers who are as passionate as they are about nurturing and protecting their brands and creative works, and they brought this vision to fruition by opening Kelly IP in May 2013. In doing so, the partners leveraged their 110 combined years of 'big law' IP experience – including leading hundreds of civil litigations and thousands of oppositions and cancellations, sending thousands of demand letters, filing hundreds of UDRP complaints, clearing thousands of marks, and filing, prosecuting and maintaining tens of thousands of trademark applications and registrations – and created a firm with a collaborative, team-oriented approach.
The firm immediately established an international reputation by scoring significant litigation victories in trademark cases before the courts and the TTAB, counselling on cutting-edge issues for many of the world's leading brands, and being recognized as a leading firm for online enforcement. Kelly IP has been consistently ranked as a top firm nationally for both contentious and non-contentious trademark work by IP Stars and others (e.g., Legal 500, World Trademark Review 1000, Managing Intellectual Property) and has received national awards for both trademark litigation and prosecution. We believe that the following client feedback from a prominent publication best sums up Kelly IP: "What makes its group of all-stars super-competitive is that you receive a world-class service at a significantly reduced rate – you get so much for your money."

We’re proud to work with some of the world’s most dynamic organizations and the leaders who drive them. We know that on any given day you’re tackling competition, corporate development, asset protection, talent management—some days all of the above. While there’s a bevy of smart folks out there to help you address them on a case-by-case basis, there are few who have the breadth and depth of focused knowledge to help you attend to them all and stay ahead of what’s next.

That’s McDermott.

When you hire us, you don’t just get the experience of an individual. You get a purpose-built, tightly woven network of legal thought leaders who marry their passion for business with a deep, focused understanding of the law.

And your team isn’t just the lawyers working on your business day one. It’s also their colleagues around the world who guide and advise around the edges—the ones who add diverse, nuanced perspectives to elevate strategy and surface highly effective—but often unexpected—solutions when a “simple” transaction becomes a bet-the-company deal or a basic arbitration turns into multi-year litigation.

We don’t just promote this approach—we thrive on it. We know that it’s our ability to tap into the particular knowledge of our individual lawyers and then to harness their collective experience that makes us uniquely qualified to help our clients move faster and propel their success.

You can see it the results we deliver and you’ll feel it when you meet with us to talk about your needs. You’ll know that we’re more than “just” lawyers. We’re scientists, accountants, analysts, policy makers, money managers and family members who love the law. We bring all of those experiences to bear for your business and the people you serve.

Most importantly, we’re committed to helping you make real progress against your goals—to turning those big ideas into actionable plans—and to making it as easy and enjoyable as possible.

Barnes & Thornburg’s Intellectual Property practice is among the largest in the country, with nearly 130 IP attorneys and professionals and 75 registered patent attorneys and agents. Our clients know that their intellectual property — inventions, brands and trade secrets — are as valuable as their factories, laboratories and inventories. We believe that intellectual property must be cultivated and nourished to grow as an asset and without the right care, it will wither.

Our team works diligently to help clients succeed in overseeing and protecting their valuable IP with employees, customers, partners and competitors, and to avoid infringement of the IP rights of others. We position and leverage our client’s critical IP in industry and specialized markets, and defend patent, trademark and copyright integrity in the judicial system and in agency review and appeals.

With decades of experience, we understand that the many types of IP assets drive core business strategy and brand development.
