The amended specification would not fail to comply with s 40. Although the Court retained a discretion to refuse amendment, RGC's objections based on delay, alleged exploitation of wide claims, non-disclosure, foreign applications, the petty patent and the purpose of catching the SREP process did not justify refusal; the delay was explained, the relevant purposes were sufficiently disclosed or not disqualifying, and WIM's conduct...

Legal Issues

  1. 1 ['Whether the proposed amendments would claim matter not in substance disclosed in the specification as filed contrary to s 102(1) of the Patents Act 1990.' 'Whether the proposed amendments would result in claims not in substance falling within the scope of the claims before amendment contrary to s 102(2)(a) of the Patents Act 1990.' 'Whether, as a result of the amendments, the specification would fail to comply with s 40(2) or s 40(3) of the Patents Act 1990.' 'Whether the Court should refuse the amendments in the exercise of its discretion despite their being otherwise allowable.']

Ratio Decidendi

The proposed amendments were allowable because they either made express matters already implicit in the accepted specification or claimed matters in substance disclosed in the specification as filed, and they narrowed rather than enlarged the scope of the claims. The amended specification would not fail to comply with s 40. Although the Court retained a discretion to refuse amendment, RGC's objections based on delay, alleged exploitation of wide claims, non-disclosure, foreign applications, the petty patent and the purpose of catching the SREP process did not justify refusal; the delay was explained, the relevant purposes were sufficiently disclosed or not disqualifying, and WIM's conduct...

Court Disposition

Application granted; the Court directed amendment of the patent specification.

Orders

  • ["Australian Letters Patent No 639,089 be amended in accordance with the schedule to the applicant's notice of motion filed 20 January 1997." 'The Court will hear counsel on the question of costs.']
