Article 10, paragraph 1, of the TRIPS agreement provides that a computer program is a type of work that can be protected by copyright: debate on patents free software List Computer programs, whether in the source code or object, must be protected as literary works under the Berne Convention (1971). The only exceptions allowed to this provision are defined in paragraphs 2 and 3 of the same article 27 and do not mention software or computer programs. The following elements may be excluded from patentability by WTO members in the context of the TRIPS trip: (…) Patents must be available for all inventions, whether products or processes, in all technological fields, as long as they are new, inventive and suitable for industrial application. (…) Patents must be available and patent rights must be acceptable without discrimination as to the location of the invention, the technological field and whether products are imported or manufactured locally. There has been no procedure for resolving software patent disputes. Its relevance to patentability in areas such as computer-implemented business methods, computer science and software information technology remains uncertain, as the TRIPS agreement is interpreted as all legal texts . This argument has been used by some opponents of software patents to assert that software patents are not authorized by the TRIPS agreement.  TRIPS manuals do not see any conflict, z.B. notes Correa-Yusuf that software patents complement copyright because copyright does not protect the underlying ideas. The WTO Agreement on Trade-Related Intellectual Property Rights (TRIPS) in particular Article 27 is sometimes mentioned in the political debate on the international legal framework for software patentability and whether computer-based software and inventions should be considered a technological domain. Although paragraphs 2 and 3 of Article 27 members do not mention it as an exception, “pure software” is not considered an invention by European law.  States parties to the TRIPS agreement, i.e.
WTO member states, have decided that patents should be issued indiscriminately in all areas of technology (art.
