Read full decision. Generated by ChatGPT:
This appeal concerns a Federal Court decision regarding the invention and ownership of a patent for a polymeric drilling fluid used in oil drilling. The Court granted a declaration that a certain individual is the sole inventor and that a drilling services company is the rightful owner of the patent. The appellants contested this finding, arguing that the application was barred by res judicata, the Alberta Limitations Act, and a prior release agreement that allegedly precluded claims against the inventor. They also asserted errors in the Federal Court's determinations regarding inventorship and ownership. The appellate court found that while the Federal Court made an error concerning the chain of title, it did not impact the outcome. Consequently, the appeal was dismissed, upholding the Federal Court's conclusions regarding inventorship and ownership of the patent.
