PAC Mining Pty Ltd v Esco Corporation [2009] FCAFC 18

On proper construction, the claimed 'lock' requires a rigid component received into an opening in the wear member that secures the wear member to the boss by maintaining separation, not a bolt/nut arrangement that holds components together; the appellant's J-bolt and T-bolt assemblies do not infringe claims 1 and 51 of Jones II or claim 1 of Jones III. Further, the inventions as claimed in those claims were not established to be obvious, and the claimed inventions had fair basis in the specification.
