CCOM P/L v Jiejing P/L

In the case of CCOM P/L v Jiejing P/L, the Federal Court of Australia was tasked with determining the validity and infringement of Petty Patent No. 616,154, which pertained to a computer program for word processing of Chinese language characters. The patent holder, CCOM P/L, sought to enforce the patent against Jiejing P/L, which was alleged to be infringing the patent. The dispute arose from an earlier decision by the Commissioner of Patents that the patent was invalid, a decision which was subsequently overturned by the Full Court.

The primary legal issues before the Court involved the interpretation and application of the Patents Act 1990, particularly in relation to the definition of a 'manner of manufacture' and the requirements for patentability, including novelty, inventive step, and fair basing. The Court had to decide whether the patent adequately disclosed a manner of manufacture, whether it was novel, and whether the claims were fairly based on the disclosure. Furthermore, the Court needed to determine if Jiejing P/L's activities constituted infringement of the patent, given its invalidity.

The Court found that Petty Patent No. 616,154 did not sufficiently disclose a manner of manufacture as required by the Act. The patent's claims were not supported by the disclosure, and the Court held that the patent was invalid due to a lack of novelty, as it did not meet the criteria for patentability. The Court also noted that the alleged infringement by Jiejing P/L did not revive the invalid patent, and therefore, the infringement claim was not tenable. Consequently, the Court set aside the earlier revocation application and declared the patent invalid, while allowing the appellants the opportunity to amend the patent application in accordance with the statutory provisions. The Court dismissed the appeal and ordered the appellants to pay the respondents' costs.
