complementary goods

complementary goods. Trademarks. Products that are typically used together, such as pancake syrup and pancake mix, or motion-picture projectors and film. • Trademark law may prevent the use of a similar mark on complementary goods because consumers may be confused into thinking that the goods come from a common source. The patent-misuse doctrine may provide a defense in an infringement suit if the plaintiff has used its patent rights to gain market control over unpatented complementary goods. — Also termed complementary products. See AUNT JEMIMA DOCTRINE; PATENT-MISUSE DOCTRINE. [Cases: Trade Regulation 182.

1. C.J.S. Trade-Marks, Trade-Names, and Unfair Competition §§ 170, 172, 185.]
