ToolGen Incorporated v Fisher (No 3)

ToolGen Incorporated sought to amend its patent application following an appeal determination, which raised issues concerning the scope and validity of its claims. The dispute was heard in the Federal Court of Australia. The key legal issue revolved around whether the proposed amendments to the patent claims were permissible under section 102 of the Patents Act 1990 (Cth), particularly in the context of correcting what appeared to be an obvious mistake in the claims.

The court examined the nature of the proposed amendments and whether they were allowable under the statutory provisions. It considered whether the patentee had discharged the onus of establishing that the amendment should be permitted, taking into account factors such as the timing of the amendment request, the conduct of the patentee, and any detriment to the respondent or the public that might result from the delay in seeking the amendment. The Full Court outlined various considerations pertinent to the exercise of this discretion, emphasizing that the discretion exists for the benefit of the patentee and that unreasonable delay could be a significant factor in refusing the amendment. The court also stressed that the focus should be on the patentee’s conduct rather than the merits of the invention.

Upon reviewing the specific circumstances of the case, the court found that the composite claim indeed contained an obvious mistake that was apparent on the face of the specification. The court concluded that the patentee had failed to promptly seek the amendment and had thereby delayed unreasonably. Consequently, the court exercised its discretion to allow the amendment, setting aside the previous decision of the Delegate of the Commissioner of Patents, with the exception of the costs awarded to the opponent. The court ordered the patent application to proceed to grant with the amended claims as set out in the Annexure to the orders. Additionally, the appellant was required to pay the respondents’ costs incurred up to a specified date and to serve a copy of the orders on the Commissioner of Patents within seven days.
