CQMS Pty Ltd v ESCO Group LLC

The matter between CQMS Pty Ltd and ESCO Group LLC was heard in the Australian Patent Office. The dispute was an opposition to the grant of a patent for a machine for removal and installation of wear members used in earth working equipment. The court had to determine if the claims in the patent application lacked novelty and an inventive step, and if so, whether the patent should be revoked.

The legal issues before the court were whether Claims 1 and 21 of the patent lacked novelty and an inventive step. The opposition was based on various pieces of prior art, including documents by Dietens, Derycke, Zrostlik, and Demmler, as well as common general knowledge. The court had to decide if these pieces of prior art disclosed the same invention as claimed by the applicant.

The court found that Claims 1 and 21 lacked novelty in light of Derycke, as they were essentially the same invention. Consequently, these claims also lacked an inventive step in light of Derycke. The court further found that the claims were obvious in light of common general knowledge alone, as they merely described functionally-described components performing well-known and well-understood steps, without defining the features of these components in a meaningful way. The court concluded that the claims were essentially a “wish list” of undefined components to perform well-known and well-understood steps.

The court ordered that Claims 1, 4-12, 16, 17, 20-23, 25-30, 32, and 33 of the patent application lacked an inventive step. As a result, these claims were revoked. The court also awarded costs to the opponent.
