Australian Mud Company Pty Ltd v Coretell Pty Ltd [2011] FCAFC 121

Australian Mud Company Pty Ltd v Coretell Pty Ltd [2011] FCAFC 121

On the proper purposive construction of the claims, the word "device" as used in the phraseology of the claims referred consistently to a single physically interconnected or unitary orientation device, not to an apparatus in two separate and separated parts. The accused apparatus, consisting of a down hole component and a handset, was therefore outside the scope of the claims and did not infringe. The primary judge's construction was correct, and the appeal was dismissed.

Procedural Posture

Patent Infringement Appeal and Appeal Concerning Unjustifiable Threats of Infringement / Full Court Appeal From Australian Mud Company Pty Ltd V Coretell Pty Ltd [2010] FCA 1169

Legal Issues

  1. 1 ['Whether the word "device" in the patent claims encompassed a core orientation tool in two or more separate and separated parts or was limited to a unitary tool in a single assemblage.' 'Whether the accused apparatus, comprising a down hole component and a handset, infringed the patent on the proper construction of the claims.' 'Contingently, whether the claims would comply with s 40(3) of the Patents Act 1990 (Cth) if construed to encompass the accused apparatus.']

Ratio Decidendi

On the proper purposive construction of the claims, the word "device" as used in the phraseology of the claims referred consistently to a single physically interconnected or unitary orientation device, not to an apparatus in two separate and separated parts. The accused apparatus, consisting of a down hole component and a handset, was therefore outside the scope of the claims and did not infringe. The primary judge's construction was correct, and the appeal was dismissed.

Court Disposition

Appeal dismissed; appellants to pay the respondents' costs.
