The intellectual property team provides full life-cycle patent support, from initial identification of patentable ideas in our clients’ business, to prosecution before the US Patent and Trademark Office, to enforcement, licensing, and patent assets sales and acquisitions.  Our clients range from startups preparing for initial investment and growth, to multi-national, Fortune 50 companies looking to strategically grow and exploit their patent portfolios.  Butzel patent attorneys prepare and prosecute domestic and foreign patent applications for clients in the software, pharmaceutical, life sciences, automotive, technology, and higher education industries, among others. We handle patent prosecution, appeals, reexaminations, non-infringement and invalidity opinions, post-grant procedures before the USPTO, state and federal court litigation, and patent portfolio management.  We bring true value to our clients’ patent portfolios through strategies tailored to their individual business needs and budgets while achieving maximum protection for their inventions.  In conjunction with the litigation team, we also defend against allegations of patent infringement both from competitors and non-practicing entities
