This case was one of Ryan Abbott’s attempts (on behalf of Dr Stephen Thaler) to persuade patent offices across the world to recognise the AI tool “DABUS”, as the inventor in certain patent applications. Case J8/20 related to two European patent applications (EP3564144 and EP3563896) which failed to designate a natural legal person as the inventor, instead specifying the AI system DABUS as the inventor. The AI tool was identified as the inventor by Thaler on the basis that it generated and identified the novelty of the respective inventions.
Decision
The Board of Appeal announced its decision to dismiss the appeal in December 2021, with the reasoned decision to follow. It dismissed the appeal on the basis that under the European Patent Convention (“EPC“) the inventor designated in a patent application must be a person with legal capacity. In the written reasons, the Board also concluded that (i) the statement of origin of the right to the European patent (i.e. the second sentence of Article 81 EPC) had to conform with Article 60(1) EPC and so also required a human inventor; and (ii) the EPO was competent to assess whether the statement referred to a situation which encompassed Article 60(1) EPC. Set out below are some additional comments to note from the Board’s full decision.
Inventor: legal capacity
The Board explains in its full decision that an inventor must be someone with legal capacity in order to satisfy the requirements of Article 81 EPC, in light of the ordinary meaning of the terms “inventor” and “person”. As AI is not a person and as such does not have legal capacity (e.g. rights to own property), the Board of Appeal concluded that under the EPC an inventor must be a human being.
The additional reasons for this conclusion were:
- Provisions of the EPC that refer to “inventor” use the terms “person” or “legal predecessor”.
- Article 60(1) vests rights to the patent to the inventor which postulates a person with legal capacity.
- The purposes of the inventor designation provisions are to: (i) confer and to protect rights of the inventor, (ii) facilitate enforcement of potential compensation claims and (iii) identify a legal basis for entitlement to the application. Designating a machine without legal capacity cannot serve these purposes.
- There is no basis in the EPC for an argument that an AI inventor should be permitted because of a right of the public to know who the inventor is and how the invention was made.
- Even if such a proposition were relevant under the EPC, where an AI system contributed to the invention applicants can explain how the invention was made in the description.
Statement of origin of right to European patent
Article 81 (second sentence) requires a statement indicating the origin of the right to the European patent, whereas Article 60(1) creates the right to the European patent, vests this right in the inventor and provides for transferability of that right. On the basis that these two provisions are linked and the notions of inventor and successor in title should be interpreted uniformly and autonomously, the Board concluded that the statement of origin of the right must be consistent with Article 60(1) and so also requires a human inventor. This is the case where the declaration identifies the applicant as the employer or the successor in title of the inventor.
EPO competency
The Board concluded that the EPO can and should examine whether an inventor has been designated before addressing the patentability assessment. It explained this is in light of Article 90(3) which states “the European Patent Office shall examine (…) whether the requirements in Articles 14, 78 and 81 (…) have been satisfied”. Where the applicant is different to the inventor, then the EPO should also assess if the statement of origin to the right to the European parent refers to a situation encompassed by Article 60(1) EPC. This is a mere formal assessment and the EPO does not need to assess if the applicant was entitled to file the application or consider any law or evidence.
Referral to the Enlarged Board of Appeal
The Board refused Thaler’s request to refer two questions to the Enlarged Board of Appeal (“EBA”) relating to the applicability of the requirement to designate an inventor. This was because the answers to Thaler’s questions were not necessary to decide on the appeal (as they would not change the overall outcome).
Final comments
Interestingly, the Board determined that there is no issue of unequal treatment of applicants – noting that nothing prevents the user / owner of a device designating himself as the inventor (see 4.6.6 of the decision). This reflects the findings in Thaler’s German proceedings, where the German Federal Patent Court held that although AI generated inventions are patentable in practice, the listed inventor must be human.
