Cooley opened its Seattle office in October 2008 with a team of four partners and nine associates. Our Seattle group of attorneys have significant life sciences, technology and clean technology practices, representing emerging growth companies, established technology businesses, venture capital firms and investment banks. We represent clients at all phases of their business cycles and provide expert counsel for the most sophisticated and challenging transactions and litigation matters faced by start-up, emerging, and established companies, venture capital and private equity funds and underwriters.

By combining the team's long-standing connections and client base in the Pacific Northwest business community with Cooley's existing clients in the region, the office works with all of the leading venture capital firms and many of the most well-known emerging companies in this important technology location.  In addition, the life sciences practice represents leading regional life sciences companies, as well as many leading national and international research institutions, including a substantial practice involving Asian life sciences companies.

Our practice includes both business and litigation services and leverages the resources of Cooley attorneys across the country. As such, our clients receive the support and expertise of an attorney team that is committed, knowledgeable and experienced with the intricacies of their particular business.
