Reflex Instruments Asia Pacific Pty Ltd v Globaltech Corporation Pty Ltd [2023] FCAFC 158

Reflex Instruments Asia Pacific Pty Ltd v Globaltech Corporation Pty Ltd [2023] FCAFC 158

The appeal was dismissed because, notwithstanding the finding that the primary judge unduly restricted the meaning of 'downhole equipment' and 'downhole data gathering system,' Reflex did not show error affecting the ultimate conclusion that the asserted claims were both novel and involved an inventive step; the invention as claimed was not anticipated by Sun or Iizuka, as the necessary 'electromagnetic signal direction altering means' and 'reflector' were not disclosed in those documents; the perception of the need for improvement was not part of the common general knowledge, and inventiveness lay in conceiving the improvement, so the claims were not rendered obvious.

Legal Issues

  1. 1 ["Proper construction of 'downhole equipment' and 'downhole data gathering system' in the patent claims" 'Whether terms exclude oil and gas drilling and wireline telemetry equipment' "Whether phrases 'electromagnetic signal direction altering means', 'reflector' and 'communicate wirelessly' exclude optical fibre" 'Whether invention as claimed lacked novelty in light of prior art (Sun and Iizuka)' 'Whether invention as claimed lacked an inventive step on the basis of common general knowledge (alone or combined with Sun/Iizuka)']

Ratio Decidendi

The appeal was dismissed because, notwithstanding the finding that the primary judge unduly restricted the meaning of 'downhole equipment' and 'downhole data gathering system,' Reflex did not show error affecting the ultimate conclusion that the asserted claims were both novel and involved an inventive step; the invention as claimed was not anticipated by Sun or Iizuka, as the necessary 'electromagnetic signal direction altering means' and 'reflector' were not disclosed in those documents; the perception of the need for improvement was not part of the common general knowledge, and inventiveness lay in conceiving the improvement, so the claims were not rendered obvious.
