In semiconductor industry, the basic solution for production of integrated circuit with desired function is the disposition of in-circuit elements in extent of integrated circuit and their interconnection. Such solution, or its symbolization, has undoubtedly character of an inventive work, which has to be protected against piracy and unjustified enrichment. For these purposes serves the entry of certain topography of semiconductor products to the national register. The entry can be done only in terms of filing of an application by the Office. The right to the protection of topography can be claimed only by nationals of the Czech Republic or persons, who have residence in the Czech Republic. Others only on condition of reciprocity. The application procedure is made by the Office in terms of registration principle, the Office thus doesn't examine the material conditions of protection. The entry can be attacked by cancellation. The Office administers the register of topographies in which enters all conclusive statements and which is accessible for public.
