Raphael Bellum PLLC is an intellectual property law firm whose attorneys have extensive experience in patent and trademark prosecution, copyright matters, licensing, portfolio management, and client counseling.

The firm was founded as J.A. Lindeman & Co. in 2009 by our friend and mentor, Jeffrey A. Lindeman, Ph.D., who after decades of leading patent practice groups at top global law firms, sought to establish a “firm of choice” for its clients and our team members by combining capabilities typically associated with large IP firms with an approach to client representation that prioritizes analysis and creativity. We rebranded ourselves as Raphael Bellum PLLC in 2022 following Jeff’s retirement from the firm. The next year, Dunner Law PLLC brought its highly acclaimed trademark and copyright expertise to Raphael Bellum through a merger of the two firms. Dunner Law was founded in 2004 by renowned Trademark Law and policy leader, Lisa Dunner, who is recognized as one of the world’s top 250 women in IP and by World Trademark Review 1000 as one of the top 1000 trademark attorneys in the world.

As chemists, biomedical researchers, biotechnologists, and engineers ourselves, we understand the unique challenges that our patent prosecution clients face.
Our clients are innovators in a wide range of fields, including information technology, chemistry, biology, biotechnology, engineering and design, manufacturing, retail, and publishing. They are business professionals, universities, startups and industry leaders, publishers, content creators, small businesses, and multinational corporations—all of whom are focused on developing the technologies, services, and brands that will define our future. We are proud to help them protect and commercialize their creations.

As chemists, biomedical researchers, biotechnologists, and engineers ourselves, we understand the unique challenges that our patent prosecution clients face. We combine our technical expertise with our years of legal and business experience to support our clients in all areas of patent before the U.S. Patent and Trademark Office and United States courts, as well as with managing the prosecution of international patent portfolios.

The firm’s trademark prosecution practice focuses on counseling and guiding clients through the entire trademark process, from initial consultation and clearance searches, thorough application strategy and interactions with the USPTO, and ultimately to successful registration. In addition to enjoying a strong track record of obtaining federal registrations for its clients’ marks, the firm maintains, monitors, and enforces trademark rights on their behalf. We also are one of a select few firms chosen by Amazon.com as a “Top IP Accelerator Firm” to help Amazon sellers protect their intellectual property by joining the Amazon Brand Registry. More information about our services in this area can be found here.

In addition to our patent and trademark prosecution practices, we also assist our clients in other areas of intellectual property, including representing them in licensing negotiations, business negotiations and transactions. We also provide due diligence, freedom-to-operate, patent non-infringement, and invalidity opinions.  We are proud of our reputation of producing high quality work and building superior client relationships. But it is not just our experience that sets us apart from other firms. We combine sound experience with insight and imagination to bring creativity and enthusiasm to the work we do for our clients. We believe that just as originality and innovation are the hallmarks of intellectual property and patents, those attributes are ingredients for success and for satisfying work – for clients and the firm.
