Continental Soya Co. Ltd. v. J. R. Short Milling Company (Canada) Ltd.

Continental Soya Co. Ltd. v. J. R. Short Milling Company (Canada) Ltd.

A product derived from a vegetable is patentable as a "manufacture or composition of matter" when the inventors have contributed patentable invention in methods of extraction and preservation that produce a new and useful product; where the methods are physical rather than chemical, s.40 does not preclude claims to the substance; appropriately described claims to the same nature of substance from other vegetables are not necessarily too broad. The patents in suit therefore were valid and infringed.

Procedural Posture

Patent Infringement Appeal / Appeal to the Supreme Court of Canada From Judgment of the Exchequer Court of Canada

Legal Issues

  1. 1 Whether a product derived from a vegetable (soya bean) is patentable as a "manufacture or composition of matter" under s.2(d) of the Patent Act
  2. 2 Whether the invention was mere discovery or involved patentable invention in extraction/preparation methods
  3. 3 Whether the substance/process falls within s.40 restriction on "substances prepared or produced by chemical processes"

Ratio Decidendi

A product derived from a vegetable is patentable as a "manufacture or composition of matter" when the inventors have contributed patentable invention in methods of extraction and preservation that produce a new and useful product; where the methods are physical rather than chemical, s.40 does not preclude claims to the substance; appropriately described claims to the same nature of substance from other vegetables are not necessarily too broad. The patents in suit therefore were valid and infringed.
