About Brian E
Brian E Haan combines legal training and engineering credentialing in a practice that centers on patents and intellectual property. He earned his Juris Doctor from Chicago-Kent College of Law, Illinois Institute of Technology, completing law school in 2008. He also holds professional registration as an engineer in Ohio, a qualification that informs his approach to technical legal issues.
After law school, Haan qualified as a registered patent lawyer at the United States Patent and Trademark Office. He is admitted to practice in Illinois and before the Federal Circuit. Those admissions enable him to handle matters that move from state-level disputes into federal appellate review, and to prepare and prosecute patent applications at the USPTO.
His background bridges two professions. The combination of a law degree and a Professional Engineer license positions him to address patent prosecution and related IP work that involve technical subject matter. He commonly advises on patentability, claim drafting, examiner responses, and prosecution strategy. His USPTO registration allows him to prosecute patents on behalf of inventors and companies.
At Lee Sheikh Megley & Haan, he practices alongside attorneys who handle litigation, counseling, and transactional matters. His role involves preparing patent applications, responding to office actions, and assisting clients through the examination process. When matters require litigation or appeals, his Federal Circuit admission supports participation in appellate proceedings.
Clients who bring technical inventions often seek counsel that understands both the engineering and legal dimensions. Haan’s engineering credential and USPTO registration allow him to read technical disclosures and translate them into patent claims and supporting arguments. He also works with outside experts and inventors to develop strategies for protecting innovations.
In the office, he contributes to case preparation and prosecution workflows. He coordinates filings, tracks deadlines, and manages communications with examiners and opposing counsel when disputes arise. His practice includes counseling on filing strategies to align with business goals and enforceable intellectual property rights.
He currently represents clients in patent and related intellectual property matters at Lee Sheikh Megley & Haan.
