In the Matter of Patent Application 531592 in the Name of THE ELECTRICITY TRUST OF SOUTH AUSTRALIA
‑ and ‑

In the Matter of Opposition thereto under Section 59 by ZELLWEGER USTER PTY. LTD.

DECISION OF A SUPERVISING EXAMINER OF PATENTS:
         In my decision in this matter dated 28 August, 1986 I found that claims 1 and 7 of the complete specification did not comply with section 40. I allowed the applicant sixty days in which to propose amendments to cause all claims to comply with section 40.
         On 26 September, 1986 the applicant lodged a section 77 request to amend the complete specification. Subsequent to proceedings under section 79, the request was advertised on 4 December, 1986 and allowed on 7 May, 1987, the amendments being incorporated into the complete specification at that time. The opponents were given twenty one days from 26 June, 1987 to request a hearing on the specification as amended, and did not lodge such a request within the time period.
         I am satisfied that the amendments remove the grounds for the earlier findings and thus I am of the opinion that there is no lawful ground of objection to the application and complete

specification. I direct therefore that the application and complete specification as amended proceed to sealing, subject to any appeal.

CaseChat Overview and Summary

The Electricity Trust of South Australia, the applicant, was involved in a dispute with Zellweger Uster Pty. Ltd., the opponent, concerning patent application 531592. The case was heard by a Supervising Examiner of Patents, focusing on the compliance of the patent claims with the provisions of the Patents Act 1990 (Cth). The dispute centred on whether the claims in the patent application met the legal criteria for patentability, specifically under section 40 of the Act.

The legal issues before the court involved the interpretation and application of section 40 of the Patents Act, which pertains to the disclosure of the invention. The court had to determine whether the initial claims in the patent application sufficiently disclosed the invention and whether the proposed amendments by the applicant addressed the deficiencies identified. The opponent's role was to argue against the patentability of the claims, and the court had to weigh these arguments in its decision.

The Supervising Examiner concluded that the initial claims did not comply with section 40, but found that the amendments proposed by the applicant successfully rectified these issues. The amendments were deemed to adequately disclose the invention, thus meeting the statutory requirements. As a result, the court allowed the patent application and complete specification, as amended, to proceed to sealing. This decision was made subject to any potential appeal by the opponent within the prescribed timeframe.

The final orders of the court directed that the patent application, as amended, should proceed to sealing, with the opponent's right to appeal preserved. This decision underscored the importance of clear and complete disclosure in patent applications, ensuring that the statutory requirements for patentability are met.
