CQMS Pty Ltd v ESCO Group LLC

In the case of CQMS Pty Ltd v ESCO Group LLC, the primary focus was on an opposition to the grant of a patent filed by CQMS for a monitoring system for earth working equipment. The opposition, brought by ESCO Group LLC, contested the patentability of the invention on several grounds including novelty, inventive step, sufficiency, support, and clarity. The hearing of the opposition took place in Canberra on 28 October 2019, following the completion of evidence in support, answer, and reply on 20 December 2018, 8 April 2019, and 11 June 2019, respectively.

The central legal issues before the court were whether the invention as claimed in the patent application met the statutory requirements for patentability under the Patents Act 1990. Specifically, the court had to determine if the claims 1, 6, 7, 15, and 18 of the patent application lacked an inventive step, and if the opposition on other grounds was successful. The court also needed to consider whether the claims were clear, sufficiently disclosed, and supported by the specification.

In its decision, the court found that claims 1, 6, 7, 15, and 18 did indeed lack an inventive step over the prior art, rendering them invalid. The court held that the concept of monitoring the performance of the bucket and wear parts was already known in the field, and the invention did not sufficiently advance the art beyond what was already known. Regarding the other grounds of opposition, the court found that the opposition was unsuccessful as the invention met the requirements for novelty, sufficiency, support, and clarity. Consequently, the opposition to the grant of the patent was upheld in part, and the patent was refused for the claims that lacked an inventive step.

The final orders of the court were that the opposition to the grant of the patent was allowed in relation to claims 1, 6, 7, 15, and 18 for lacking an inventive step. The costs of the opposition were awarded to ESCO Group LLC.
