The legal term of “Well-Known Trademark” first appeared in the 1883 Paris Convention for the Protection of Industrial Property, which sets forth the principles for granting special protection to well-known trademarks. In recent years, Sino-US disputes over intellectual property protection have the trend to upgrade, and among these disputes, well-known trademark protection is an important cornerstone. In recent years in China, the well-known trademark protection system is still relatively week comparing to developed countries, so the protection of well-known trademark becomes particularly urgent and necessary under the threat of trade sanctions and market access losses from external pressure from the United States. Compared to the USA, the Europe and other Asian countries, we shall make some improvements including: (1) Proposed the establishment of a special law to protect well-known trademarks, (2) Clear definition of well-known trademark, (3) Clear identification of institution for recognition of well-known trademark, (4) Strengthen the protection of well-known trademarks on the network, (5) Establish a joint trademark and defensive trademark system, (6) Increase legal enforcement. Moreover, the time is ripe for adopting anti-dilution provisions to afford greater protection to truly well-known trademarks.
