Procedural Posture

Review Application / Application to Set Aside Amendments to Patent Claims

Legal Issues

  1. 1 Whether the first amendment to the patent claims contravened section 51(7) of the Patents Act by including claims not wholly within the scope of the original claims.
  2. 2 Whether the second amendment contravened section 51(6) of the Patents Act by introducing new matter or claims not fairly based on the original specification.

Ratio Decidendi

The court found that the amendments to the patent claims did not contravene sections 51(6) or 51(7) of the Patents Act. The change from 'surface connection' to 'surface connector block' did not broaden the scope of the claim, as 'connection' in the context of claim 1 referred to a connecting part, not a mere state of connection. The features added by the amendments, such as the arcuate cross-section and array, were broadly described and depicted in the original specification and figures, and thus did not introduce new matter or claims not fairly based on the original disclosure. The court applied an objective test, interpreting the claims in their ordinary grammatical sense and...

Court Disposition

Application dismissed with costs.
