What began as a small team of IP attorneys in 1994 has grown into one of China's most trusted full-service intellectual property firms with a global reach.
Kangxin Partners, P.C. was established in Beijing as one of the first private intellectual property law firms in China, helping domestic and international clients navigate the developing Chinese IP landscape.
Significantly expanded beyond traditional patent and trademark prosecution into IP litigation and strategic consulting — marking Kangxin's transition into a full-service IP powerhouse capable of handling complex legal disputes.
Became one of the earliest IP firms in China to obtain ISO 9001 Quality Management System certification, reflecting an early commitment to international service standards and rigorous quality control across all legal workflows.
Celebrated two decades of service while solidifying top-tier status with consistently high rankings in Managing IP (MIP), IAM Patent 1000, and World Trademark Review (WTR 1000).
Launched the Kangxin IP Platform — a comprehensive, AI-driven SaaS tool for intellectual property management. This marked a major pivot toward "IP + IT + AI," enabling clients to manage search, filings, renewals, and monitoring through an automated digital interface.
Achieved a landmark in digital security with three major ISO certifications: Information Security Management (ISO 27001), Cloud Service Information Security (ISO 27017), and Privacy Information Management (ISO 27701) — ensuring the highest global standards for data protection and client privacy.
