Spanish legislation grants a period of protection of 10 years for topographies of semiconductor products, which are integrated semiconductor circuits known as "chips". The subject-matter of protection is not the integrated circuit itself but the way in which it is physically mounted and the physical arrangement of all its elements.

For a semiconductor product to qualify for protection from the Spanish Patents and Trade Marks Office, the topography must be the result of the creator’s own intellectual efforts and must not be commonplace among manufacturers of semiconductor products.The law requires originality and creativity.

The governing provisions are to be found in Law 11/1988, the result of the transposition to Spanish law of Community Directive 87/54/EEC of December 16, 1986.
