Patent Counseling & Prosecution

Cooley's Patent Counseling and Prosecution practice provides sophisticated patent services to 1,000+ clients worldwide across a range of industries. The team consists of 90+ attorneys and patent professionals across the US and UK, majority of whom hold PhDs or advanced degrees in science and engineering. The team brings to bear decades of experience drafting, prosecuting, defending and opposing patents at the US Patent and Trademark Office and the European Patent Office. In addition to our on the ground coverage in the US and UK, we have a carefully vetted network of counsel with whom we partner located in key jurisdictions worldwide.

We help clients formulate and implement effective intellectual property development and protection strategies. The group's services include conducting patentability analyses, developing plans for building economically efficient patent portfolios, preparing patent applications, and corresponding with patent offices of various jurisdictions around the world to ensure global patent rights. Our lawyers also assist companies to avoid infringement of third party patent and intellectual property rights. Such services include performing third party patent searches, analyzing third-party patent and intellectual property rights, maintaining periodic patent watches on third-party competitors and preparing non-infringement and invalidity opinions.

The firm's patent lawyers are often involved in patent and commercial litigation matters, as well as patent due diligence surrounding mergers, acquisitions, funding and other transactions. Given our patent lawyers' extensive involvement in these types of matters, we have developed a deep understanding of value. As a result, we understand what creates commercial value in a patent portfolio, and have a keen appreciation of the interface between prosecution and enforcement.
