China grants enhanced protection to “well-known trademarks” (Wen Ming Shang Biao). Well-known marks enjoy cross-class protection and broader enforcement rights.
Well-known status is determined on a case-by-case basis by CNIPA or courts. Factors include: duration and extent of use, advertising investment, market share, consumer recognition, and records of enforcement. Recognition is typically granted during opposition, invalidation, or litigation proceedings.
We can advise on strategies to build evidence for well-known trademark recognition.
