DABUS

DABUS is an artificial intelligence (AI) system created by Stephen Thaler. It reportedly conceived two inventions. The filing of patent applications designating DABUS as inventor has led to decisions by patent offices and courts on whether a patent can be granted for an invention reportedly made by an AI system.
History in different jurisdictions.
European Patent Office.
The European Patent Office (EPO) refused two European patent applications naming DABUS as inventor on similar grounds as in the U.S. (see below). The two EPO decisions are under appeal, as of August 2020.
United Kingdom.
Similar applications were filed by Thaler to the United Kingdom Intellectual Property Office on 17 October and 7 November 2018. The Office asked Thaler to file statements of inventorship and of right of grant to a patent (Patent Form 7) in respect of each invention within 16 months of the filing date. Thaler filed those forms naming DABUS as the inventor and explaining in some detail why he believed that machines should be regarded as inventors in the circumstances. 
His application was rejected on the grounds that:
(1) naming a machine as inventor did not meet the requirements of the Patents Act 1977; and 
(2) the IPO was not satisfied as to the manner in which Thaler had acquired rights that would otherwise vest in the inventor.
Thaler was not satisfied with the decision and asked for a hearing before an official known as the "hearing officer". By a decision dated 4 December 2019 the hearing officer rejected Thaler's appeal. 
Thaler appealed against the hearing officer's decision to the Patents Court (a specialist court within the Chancery Division of the High Court of England and Wales that determined patent, registered design, plant varieties and semiconductor topography disputes). The appeal came on before Mr Justice Marcus Smith on 15 July 2020, who handed down his decision in "Thaler v The Comptroller-General of Patents, Designs And Trade Marks" [2020] EWHC 2412 (Pat). The judge upheld the decision of the hearing officer.
United States.
The patent applications on the inventions were refused by the USPTO, which held that only natural persons can be named as inventors in a patent application.
