YK Law

Based on an analysis of public records and firm publications as of May 7, 2026:

Firm Overview
YK Law LLP is a general practice international law firm headquartered in New York City. Founded in 2019, the firm operates U.S. offices in New York, New Jersey, and California (Los Angeles, Irvine, Glendale), along with an office in Beijing. YK Law is a co-founding member of the "Yingke Global One-Hour Legal Service Ecosystem," an affiliation that provides access to a large international network of legal professionals. The firm is not presently ranked in the AmLaw 100 or Chambers USA, and it positions itself as a comprehensive business law firm rather than a specialized intellectual property boutique.

Intellectual Property and Patent Litigation Practice
The firm lists intellectual property among its core practice areas, handling matters including patent licensing, trademark protection, and IP infringement litigation. The authoritative case data for the firm includes one patent case where it acted as lead counsel for the plaintiff. This limited public record does not indicate a specific technology focus for the firm's patent litigation practice. The firm's website describes a broad IP practice that supports a diverse, global client base, often with cross-border legal needs.

The firm’s capabilities include practice before the USPTO’s Patent Trial and Appeal Board (PTAB). Partner Aaron Borrowman’s biography notes experience representing clients in patent disputes before federal courts and the PTAB, though public data on the firm's volume of IPR or other post-grant proceedings is not available. The single tracked case shows the firm representing the plaintiff, but the overall side preference for patent matters is not clear from available information.

Key Attorneys
Key attorneys with experience in the firm's intellectual property practice include:

• Faye Yifei Deng, a Senior Counsel whose practice includes commercial and intellectual property infringement litigation. She is listed as lead counsel in the firm's single tracked patent case.
• Aaron Borrowman, a partner and registered patent attorney. His experience covers patent prosecution across various technologies, client counseling on enforcement strategies, and representing clients in patent disputes in federal court and before the PTAB.
• Henry Y. Li, the firm's Managing Partner.
