Brian S. Rosenbloom has been practicing in the field of intellectual property law for over 19 years.  He advises a wide range of clients, from Fortune 500 companies to independent inventors, entrepreneurs, and emerging businesses, in all aspects of patent and related intellectual property matters.  A substantial portion of Mr. Rosenbloom’s practice is focused on patent portfolio development and management.  Mr. Rosenbloom has helped develop and manage diverse portfolios ranging from dozens of patents to hundreds of patents.  Another significant portion of Mr. Rosenbloom’s practice is handling patent litigation matters in Federal Court, as well as before the U.S. Patent and Trademark Office, including post-grant proceedings before the Patent Trial and Appeal Board and reexaminations.  Mr. Rosenbloom’s practice also involves the preparation and prosecution of patent applications in a broad range of technologies and fields, with a concentration in the areas of telecommunications, computer hardware, and computer software.

In the early 1990s, prior to attending law school, Mr. Rosenbloom worked as a software and network engineer for General Electric Information Services in Rockville, MD, where he gained deep knowledge regarding the Internet Protocols (e.g., IP, TCP, UDP, HTTP) and how to create and manage large scale IP networks.  Mr. Rosenbloom routinely leverages this knowledge and experience when advising clients, as a large amount of patent litigation involves such Internet technology.
