Abstract: | The paper shows some of the negative effects of the use of foreign trademarks in the developing countries, taking into account the experience in Mexico. It also refers to the enactment of the new Law on Inventions and Trademarks as a response to the problems arising from that use. It contains statistical data concerning the licensing agreements registered in the Mexican Registry for the Transfer of Technology, which demonstrate the importance of the use of foreign trademarks, its cost and the type of restrictive business clauses that those agreements include. |
