Diana has always loved complex puzzles – studying each piece until the solution emerges. She applies that same determined curiosity to her IP practice. After carefully listening to each client, Diana examines every legal, business, and human element, arranging disparate pieces into elegant solutions. With Diana as their advocate, her clients can confidently develop and expand their IP strategy and portfolios.

As a seasoned IP litigator and counselor, Diana’s practice has run the gamut from counseling startups, to take-down and anti-counterfeiting campaigns, to employee departure investigations. She has represented clients before the Trademark Trial and Appeal Board, and handled trials in District Courts and before the International Trade Commission. Diana recently 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 company name, logo, and website, to their core technologies.

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.

    • C5 Medical Werks/CoorsTek Medical v. CeramTec GmbH. When manufacturer CeramTec tried to block CoorsTek Medical from using the color pink for its ceramic hip replacement products, we rose to CoorsTek’s defense. Claiming trade dress rights in the color pink, a byproduct of the chromium oxide used in CoorsTek’s manufacturing process, CeramTec sued C5 in France and Germany and threatened to file actions in other jurisdictions including the United States. Rather than wait until CeramTec filed its lawsuit in the United States, Peter counseled C5 to take the initiative to file a complaint seeking a declaratory judgment of non-infringement in Federal District Court in Denver. Following a 13-day bench trial in district court, Peter and his team won CoorsTek the right to make, offer and sell its pink ceramic hip components in the United States. Moreover, this precedential ruling confirmed that a color that is the natural result of a functional attribute described in an expired patent cannot serve as trade dress.
    • MGA v. Mattel. We obtained a widely reported jury verdict that MGA, not Mattel, owns the rights to the Bratz doll, and that Mattel stole MGA's trade secrets through a campaign of corporate espionage. MGA had previously been found to have infringed Mattel's copyright and ordered to pay $100 million. We were hired to handle the appeal. After three months of testimony, a California federal jury rejected all of Mattel's claims to the Bratz franchise and awarded MGA $310 million in damages and attorneys' fees.
    • Tekmira Pharmaceuticals Corp. v. Alnylam Pharmaceuticals, Inc. We represented Tekmira Pharmaceuticals Corp. before the Business Litigation Section of Massachusetts state court. Tekmira alleged that Alnylam had taken advantage of the collaboration to misappropriate Tekmira's secret RNAi delivery and manufacturing technology, including by applying for patents on technology developed by Tekmira and by passing off Tekmira's technology as its own. Two days before jury selection, the case settled with Alnylam agreeing to pay Tekmira $75 million in cash and near-term milestone payments, and agreeing to transfer patents and patent applications to Tekmira. Alnylam also agreed to dismiss counter-suits for patent infringement that it had filed in Massachusetts and Canada. The San Francisco Daily Journal described the settlement as a "huge win" for Tekmira. See R. Swan, "Orrick Nabs Win for Pharmaceutical Client."
