Additon, Pendleton & Witherspoon, P.A. is dedicated exclusively to the practice of intellectual property (IP) law. We provide a full range of intellectual property services for U.S. and international clients, with a focus on patent and trademark prosecution, litigation, licensing, and counseling.

We possess expertise in intellectual property law, and we rely upon our decades of experience as practitioners and counselors to guide our clients in achieving and leveraging their IP rights. We secure patent and trademark protection for our clients internationally, and we protect and enforce those rights in trial and appellate courts, including the U.S. Court of Appeals for the Federal Circuit.

We understand the importance of global intellectual property rights as demonstrated by our representation of clients from The Netherlands, Federal Republic of Germany, France, Switzerland, Italy, the United Kingdom, Ireland, New Zealand, Australia, the Republic of Korea, the Republic of China (Taiwan), the People’s Republic of China (PRC), Chile, South Africa, Singapore, and Malaysia. We are engaged in intellectual property proceedings not only in the U.S., but also throughout Europe and Asia, and elsewhere in the Americas. Our attorneys maintain our competitive knowledge in the international arena by regularly collaborating with European and Asian attorneys.

Additon, Pendleton & Witherspoon, P.A. offers all the intellectual property expertise of a larger firm, yet maintains a manageable size that encourages client engagement. This, and our position as a leading group of IP professionals in the fast-growing, business-friendly southeastern U.S., enables us to offer greater flexibility and responsiveness as compared with larger law firms.

To serve our clients, our patent attorneys are technical professionals, having degrees and experience in a broad range of science and engineering disciplines, including emerging and multi-disciplinary fields. We can readily match legal and technical expertise with our clients to provide knowledgeable, timely, and cost-effective legal services.

Our patent attorneys are registered to practice before the U.S. Patent and Trademark Office and are members of the State Bar of North Carolina or other states.
