We have the scientific, legal, and business acumen to help clients strategically develop strong, innovative, and enforceable patent portfolios that are the foundation of their business.

Our approach

The patent landscape and global business landscape are rapidly shifting. Companies are increasingly encountering obstacles in their path to commercialization. Our attorneys are at the forefront of the shifting landscape. We work closely with clients to remove obstacles, help them stay ahead of changing patent laws and judicial decisions, and provide solutions for navigating around competitors’ patents, extracting value from their intellectual property, and for protecting their assets.

As one of the leading, full-service, patent firms, we’re very experienced in helping clients maintain rights and ownership, generate significant revenue from their patents, and leverage the technologies of the future.

We understand the changing post-issuance AIA procedures and help clients leverage those procedures as part of an overall strategy to neutralize competitors.
