Clients depend on us to understand how intellectual property relates to their business, and to use that knowledge to help them fully realize the value of their intellectual property. We offer full-service IP coverage across industries, from technology, telecommunications, retail and media to pharmaceuticals and medical devices.

Clients come to WilmerHale for counseling on patent drafting and prosecution; post-grant proceedings; trademark, copyright and trade secret protection; and strategic IP portfolio development. But unlike many firms’ core-IP practices, we also offer interdisciplinary experience in technology transfer and licensing, litigation, and due diligence. These comprehensive abilities make us uniquely positioned to counsel clients on business and legal IP strategies, analyzing the value of existing IP portfolios and tailoring them to match our clients’ needs. WilmerHale is also positioned to help with IP challenges around the globe. Our lawyers include IP litigators and international trade lawyers with global experience in navigating complex international IP issues.
