Leveraging our experience filing patents and developing comprehensive patent strategies, we partner with clients that drive technological and/or scientific advancements to protect, exploit and commercialize their patents.

Our Approach

Our patent attorneys, patent agents and technical specialists hold undergraduate and/or advanced degrees in computer, electrical and mechanical engineering, biology, biochemistry, chemistry, microbiology or other related areas. Many team members also have worked outside the legal field as business industry leaders or as cutting-edge researchers. These combined experiences give us the legal and business acumen to provide clients with the strategic counsel necessary to develop strong, innovative and enforceable patent portfolios integral to business success.

Our goal is always to develop a patent strategy that neutralizes our clients’ competition. We remove obstacles and help clients stay ahead of patent laws and judicial decisions, including the ever-changing post-issuance America Invents Act procedures. Furthermore, we provide solutions for navigating around competitors’ patents. We have extensive experience helping clients maintain rights and ownership, protect assets, generate revenue from patents and leverage the technologies of the future.
