Not Too Big, Not Too Small

Greer, Burns & Crain is large enough to offer a full spectrum of intellectual property legal services to even the largest clients with extensive IP portfolios, yet is small enough to achieve cost efficiencies and intense client focus that are often not possible at larger firms. GBC is large enough to provide experienced attorneys to serve any IP need, yet is a size that ensures that clients are never neglected or lost in the shuffle.

We Value Long-term Relationships

Many of our client relationships date from prior to the founding of the firm. Long-term relationships allow us to understand the businesses we represent, provide continuity to management, and help us practically incorporate business considerations into the development of intellectual property portfolios. Our depth of knowledge developed through long term client relationships produces more efficient representation and higher quality results.

All Clients are Served by Partners

Unlike many larger firms where clients have limited access to partners, GBC believes that every client deserves an experienced partner’s attention. Our partners are consistently available to clients. Greer, Burns & Crain maintains a high partner-to-associate ratio to ensure that every client’s IP agenda is overseen and guided by a highly experienced attorney.

We Serve Clients of All Sizes

Our diverse client base encompasses large multi-national corporations, universities, small businesses and individuals. A representative few of our trusted clients include: Hewlett Packard, Bosch, Fujitsu, UGG® footwear, US Gypsum, Metso Minerals Industries, Whirlpool, Stora Enso, Biotronik AG and the Universities of Illinois, California, Missouri, and Louisville, Kentucky.

Full Range of IP Services

While a firm of modest size, we are not a micro firm. GBC’s nearly 20 attorneys are widely experienced in all aspects of the practice of IP law — a range of experience that matches or betters IP groups at larger firms.  We are far more than just a patent prosecution shop: we have extensive, international trademark and transactional practices, and our attorneys litigate IP matters around the world. We have developed industry-leading international anti-counterfeiting strategies and tools that have resulted in large scale take-downs of online networks and physical operations. We manage the intellectual property portfolios of companies from start-ups to publicly traded multi-nationals.


GBC understands the economics of businesses, and delivers excellent IP legal services within reasonable budgets. Simply put, our attorneys are committed to delivering value to clients.

Leaders in the IP Community

Many of GBC’s intellectual property attorneys lecture at seminars, law schools, and bar association events in Chicago and elsewhere regarding obtaining and securing intellectual property rights.
