E Street Enterprises Inc v CPS Housewares Pty Ltd [1995] FCA 751

E Street Enterprises Inc v CPS Housewares Pty Ltd [1995] FCA 751

The words 'a vent groove formed on said reduced diameter portion' of the piston in Claim 1 have a clear meaning that does not encompass a hole; the Fizz Keep device uses a hole, not a groove, and therefore does not infringe an essential integer of the patent. Since an essential integer is not taken, there is no infringement of claims 1 or 2. Claims 1 and 2 are not obvious, as their combination of features involved inventive steps not present in prior art or common general knowledge, and were not anticipated by any single item of prior art individually.

Ratio Decidendi

The words 'a vent groove formed on said reduced diameter portion' of the piston in Claim 1 have a clear meaning that does not encompass a hole; the Fizz Keep device uses a hole, not a groove, and therefore does not infringe an essential integer of the patent. Since an essential integer is not taken, there is no infringement of claims 1 or 2. Claims 1 and 2 are not obvious, as their combination of features involved inventive steps not present in prior art or common general knowledge, and were not anticipated by any single item of prior art individually.

Court Disposition

Application dismissed; cross-claim dismissed; no order as to costs.
