incontestability status
incontestability status. Trademarks. A classification of a trademark that meets certain criteria — including commercial use for five years after being placed on the Principal Register — as immune from legal challenge. • Although incontestability does not confer absolute immunity, it makes a challenge much more difficult. 37 USCA § 1065. Cf. DECLARATION OF USE. [Cases: Trade Regulation 252. C.J.S. Trade-Marks, Trade-Names, and Unfair Competition § 199.]
