Chong IP is a premier intellectual property law firm headquartered in Pasadena, California. Founded in 2016 by UCLA School of Law graduates Eugene K. Chong and Angela S. Chong, the practice combines engineering expertise with brand strategy, delivering flat-fee patent prosecution, trademark registration, copyright enforcement, and IP litigation for tech startups, global enterprises, and emerging creative brands.

Modern Intellectual Property Counsel in the Heart of Pasadena

For modern technology enterprises and creative ventures, intellectual property is not merely an administrative milestone; it is the cornerstone of corporate valuation. Established on East Colorado Boulevard in Pasadena, Chong IP was founded in 2016 on the conviction that clients deserve elite legal representation without the prohibitive overhead of traditional, old-school law firms. Led by partners Eugene K. Chong and Angela S. Chong, the firm pairs advanced technical and legal credentials with agile, client-centered execution. Whether prosecuting high-tech utility patents for venture-backed startups or shielding global retail trademarks against unauthorized infringement, Chong IP provides clear, strategic guidance tailored to the fast-moving marketplace.

Cutting-Edge Patent Prosecution from Skilled Patent Attorneys

Translating complex technical disclosures into granted federal patents requires deep scientific literacy. Partner Eugene K. Chong holds degrees in bioengineering and electrical engineering, is a registered patent attorney with the USPTO, and serves as an Adjunct Professor and Faculty Supervisor for the UCLA School of Law Patent Clinic. Having drafted patent portfolios for venture-funded companies and premier research institutions such as Caltech, UCLA, and Stanford, the firm provides exceptional representation. As trusted patent attorneys, Chong IP assists clients with:

  • Biomedical and Electrical Engineering Patents: Preparing and prosecuting patent applications in medical devices, image processing, telecommunications, and computer architecture.
  • Smart Home and Consumer Electronics: Securing dozens of granted utility and design patents for connected IoT hardware, video doorbells, and audio streaming technologies.
  • Patent Portfolio Strategy: Conducting inventor disclosure interviews, mapping patent landscapes, and managing international filings under the Patent Cooperation Treaty (PCT).
  • Patent Litigation in Federal Courts: Defending tech companies and enforcing proprietary patent rights in United States District Courts nationwide.

Brand Protection: Acclaimed Trademark Lawyers and Copyright Advocates

As commercial brands expand globally, imitation and counterfeit goods inevitably follow. Partner Angela S. Chong focuses her practice on trademarks, copyrights, and comprehensive brand development, counseling cosmetics companies, fashion labels, and international culinary brands. Serving as experienced trademark lawyers, copyright lawyers, and financial and ip lawyers, Chong IP assists with:

  • Trademark Clearance and Registration: Conducting comprehensive brand availability searches, drafting federal trademark applications, and managing responses to USPTO office actions.
  • TTAB Trademark Litigation: Prosecuting and defending trademark cancellations and oppositions before the Trademark Trial and Appeal Board.
  • Copyright Registration and Enforcement: Identifying proprietary digital media, marketing assets, and artistic works, while handling copyright infringement disputes and licensing agreements.
  • Trade Secret Protection: Structuring customized confidentiality protocols, non-disclosure contracts, and employee intellectual property assignment agreements.
