backSAN FRANCSICO and WASHINGTON, D.C., August 18, 2025 – King & Spalding announced today that intellectual property and technology litigators Andrew Ong and Amadou Kilkenny Diaw have joined the firm’s Business Litigation practice group as partners. Ong is based in San Francisco, and Diaw is based in Washington, D.C.
Ong’s practice focuses on complex technology disputes involving patents, trade secrets, and contracts for high tech companies. He regularly practices in federal courts, leveraging his prior experience as a law clerk in the Northern District of California, and before the U.S. Patent and Trademark Office, including handling inter partes reviews and reexaminations. He has extensive experience in a wide range of technologies, including network devices, design automation software, data storage, and semiconductor chips. He received his J.D. from UCLA School of Law and his undergraduate electrical engineering and computer science degree from UC Berkeley.
Diaw represents defendants and plaintiffs in Federal courts, at the PTAB, and in arbitrations and mediations in complex intellectual property disputes including patent infringement and trade secret matters and counsels founders, startups and established companies on intellectual property related issues. Diaw’s experience spans multiple technologies and industries, including cloud computing, hardware and software, wireless networking and communications, and consumer products among others. His clients have included Fortune 100 companies in the computing and telecommunications industries as well as emerging and high-growth technology companies. He received his J.D. from the University of Virginia School of Law and his undergraduate computer science degree from Georgetown University.
Ong and Diaw join from Goodwin Procter, where they were partners and practiced with Neel Chatterjee, who joined King & Spalding in July as partner and co-leader of the firm’s IP team.
“Expanding and elevating our IP litigation and technology industry capabilities nationwide is a priority for King & Spalding. The addition of this team is a big step in that process,” said Damien Marshall, co-leader of King & Spalding’s Business Litigation practice group. “Andrew, Amadou and Neel are entrepreneurial lawyers with impressive credentials who will be strong contributors to the growth of our IP team and the expansion of our offering to technology clients.”
“King & Spalding is a litigation powerhouse with closely interconnected practices and a strong commitment to growing its IP and technology litigation, and I am excited to be part of that,” said Ong.
“The collaboration and cross-team focus here present great opportunities to expand how I serve my clients,” added Diaw. “I am looking forward to collaborating with colleagues new and old to contribute to the growth of the firm’s IP litigation practice.”
