INDUSTRIAL PROPERTY DEPENDENT PATENT COMPULSORY LICENSING TECHNOLOGICAL INNOVATIONAbstract
This article examines dependent patents within the field of industrial property, focusing on their relationship with improvements to inventions and the limitations imposed on the exercise of patent rights. It begins with the legal nature and temporary character of patent protection and analyzes situations in which a subsequent invention depends on the use of a prior patent. The study discusses the distinction between an improvement and an autonomous invention, drawing on Brazilian and foreign legal scholarship, particularly French law. It also analyzes the treatment of dependent patents under Brazilian Law No. 9,279/1996, especially the requirements for granting compulsory and cross-licenses. Issues concerning priority, the grace period, and technology transfer are also addressed. The analysis highlights the need to balance the exclusive rights granted to the holder of the prior patent, incentives for technological development, and the exploitation of subsequent innovations representing substantial technical progress.
