Are there jurisdictions where it is possible for a corporation to be listed as the inventor on a patent? Has that ever been the case historically? I know in the US an inventor must be an individual and that's always been the case, but are there any jurisdictions where it is or has been possible?
Very interesting question.
The European Rules would seem to mirror the US rules:
Rule 19 Designation of the inventor Art. 62, 128 R. 21, 60, 163
(1) The request for grant of a European patent shall contain the designation of the inventor. However, if the applicant is not the inventor or is not the sole inventor, the designation shall be filed in a separate document. The designation shall state the family name, given names and full address of the inventor, contain the statement referred to in Article 81 and bear the signature of the applicant or his representative.
Although entities like corporations are not explicitly excluded, the requirement of family name and given name would seem to render corporate entities ineligible.
