The Portuguese IP Code dated 1940 computed the term of a patent by counting 15 years from the grant date. Later, the IP Code of 1995 introduced the term of a patent as 20 years from the filing date. However, for those patents filed before 1995 and granted after, the term calculation was made by considering the greater protection that could be given. Since the grant process could take, in some cases, seven or eight years, the duration of a patent could be more than 20 years from the application date! Further, when SPC applications based on those patents were filed, the total protection could be 27 or 28 years or even more.
