Brian started practicing patent law in May 1992 when hired by Steinberg & Raskin, a small New York City boutique firm practicing intellectual property law. Gradually, his responsibilities grew until he was responsible for maintaining patent prosecution docket including preparation and filing of patent applications in diverse fields, preparation and filing of responsive amendments, and conducting in-person interviews and appellate proceedings. In June 1999, Brian created a solo practice in suburban Long Island, New York to concentrate on developing a patent portfolio for an automotive technology development company. Shortly after Brian opened his practice, the practice grew by the addition of other clients in various manufacturing and development fields. Brian relocated his practice to north suburban Chicago in August 2010. He maintained his client base and further increased patent docket for existing and new clients. Brian provides litigation support, opinion drafting, and client development.
