Rosenbloom, Brian

Brian S. Rosenbloom is an expert in Intellectual Property (IP) counseling, patent prosecution, and patent litigation proceedings before the U.S. Patent and Trademark Office (USPTO). He has over two decades of experience in the IP field and a strong technical background in the electrical and software arts. He counsels a broad range of clients, from Fortune 100 companies to independent inventors, entrepreneurs, and emerging enterprises. 

Brian is a gifted strategist who places a high value on communication with his clients. He keeps his clients consistently informed of the status of their matters and lays out decision points in clear, precise language, along with a recommended course of action. Brian protects his clients’ most valuable innovations, and secures their market value for years to come.

Brian’s strong technical background is a great asset to his work. Prior to attending law school, he received a Bachelor’s degree in Electrical Engineering, and worked as a software and computer-networking engineer at General Electric Information Services. In this role, he gained valuable expertise in computer networking, Internet protocols, and software development. Brian’s firsthand knowledge and experience in these technologies, coupled with his strategic thinking and excellent communication skills, are a major advantage for his clients. 

Brian’s practice is focused on preparing and prosecuting patent applications in a broad range of technologies, including telecommunications, wireless networking, Artificial Intelligence (Machine Learning), video and audio encoding, cloud computing, ad-serving, and other software applications. Reflecting his significant experience in the AI/ML space, Brian was appointed to the Artificial Intelligence/Machine Learning (AI/ML) Task Force of the American Bar Association Section of Intellectual Property Law (ABA-IPL) for the 2023-2024 bar year. This is his second year being appointed to the Task Force. Brian‘s patent prosecution work is informed by both his technical expertise and his strategic mindset.

Another substantial portion of Brian’s practice involves litigating patents. He litigates before the USPTO, including post-grant proceedings before the Patent Trial and Appeal Board (PTAB) and reexaminations. Brian also litigates matters in Federal Court. He has a track record of both invalidating bad patents (patents that the USPTO never should have issued in the first place) and asserting patents against infringers who seek to take his client’s market share.

Brian’s practice also includes patent portfolio development and management. He helps develop and manage diverse patent portfolios, ranging in size from dozens to hundreds of patents. When working with these clients, Brian begins with a strategic assessment. This includes an expert evaluation of where and when challenges are likely to arise. His approach balances risk and opportunity, while analyzing and responding to competitive portfolios.
