Bartlem Pty Ltd v Cox Industries (Australia) Pty Ltd [2002] FCAFC 224

Bartlem Pty Ltd v Cox Industries (Australia) Pty Ltd [2002] FCAFC 224

The essential component 'tubular portion' or 'tubular stub axle' as claimed in Bartlem's patents requires a discrete and separate item by claim construction; Cox's mower, using only two components without a separate tubular member and not directly locking the axle to the wheel mount, did not infringe the patents. The claims did not encompass indirect locking or integration absent an explicit claim to such arrangement.
