Diana M. Rutowski Partner

Silicon Valley

As a seasoned IP litigator and counselor, Diana’s practice has run the gamut from high stakes trials, to take-down and anti-counterfeiting campaigns, to employee departure and trade secret investigations. She represents clients in District and state courts and before administrative bodies including the ITC and the USPTO. For example, Diana tried and won a complex case in which the other side sought to extend the monopoly of an expired utility patent by claiming trade dress rights in a technical product feature. Drawing upon experience handling both complex patent and trademark matters, her team successfully argued that the intersection of patent and trademark policy prevented the other side from continuing its monopoly, clearing the way for her client to enter the market. With Diana at their side, companies can rest assured that their essential assets are protected, from their core technologies, to assets including their company name, logo, and website.

While at Orrick, Diana was seconded to the City and County of San Francisco, where she had the privilege to serve as an Assistant District Attorney, and first-chair several trials. She was also seconded to Salesforce, where she learned first-hand that the law comprises just one component of a company’s overall business strategy.

Diana is also passionate about her pro bono work. For example, she represented two detainees in Guantanamo in connection with their petitions for a writ of habeas corpus, and she is currently working with the Lawyers’ Committee for Civil Rights of the San Francisco Bay Area. Before joining the firm, Diana worked for the Legal Aid of Cambodia where she assisted with the prosecution of former Khmer Rouge officials and represented individuals who sought to reclaim land rights.

Diana is a member of the International Trademark Association, of ChIPs: Advancing Women in IP and of the Harvard Club of San Francisco.
