The Proposal for a Directive of the European Parliament and of the Council on the patentability of computer-implemented inventions (Commission proposal COM(2002) 92), procedure number 2002/0047 (COD) was a proposal for a European Union (EU) directive aimed to harmonise national patent laws and practices concerning the granting of patents for computer-implemented inventions, provided they meet certain criteria.
The proposal became a major focus for conflict between those who regarded the proposed directive as a way to codify the case law of the Boards of Appeal of the European Patent Office (unrelated to the EU institutions) in the sphere of computing, and those who asserted that the directive is an extension of the patentability sphere, not just a harmonisation, that ideas are not patentable and that the expression of those ideas is already adequately protected by the law of copyright.
Following several years of debate and numerous conflicting amendments to the proposal, the proposal was rejected on 6 July 2005 by the European Parliament by an overwhelming majority of 648 to 14 votes.
On 20 February 2002, the European Commission initiated a proposal for a directive to codify and "harmonise" the different EU national patent laws and cement the practice of the European Patent Office of granting patents for computer-implemented inventions provided they meet certain criteria (cf. software patents under the European Patent Convention). The directive also took on the role of excluding "business methods" from patentability (in contrast with the situation under United States law), because business methods as such are not patentable under the different European national patent laws or under the European Patent Convention.
