Listing decision; 2008 FC 1409; Etanercept; December 23, 2008

The Court upheld the Minister's refusal to list the patent on the Patent Register on the basis that it did not contain a claim for the dosage form. The Court held that the claim of the patent claimed a metered dose inhaler for dispensing an inhalation drug formulation comprising the medicines but then construed this claim as an improvement to a device. The Court accepted the Minister's interpretation of the dosage form as an inhalation aerosol despite the definitions in the Regulations defining a dosage form as a delivery system for administering a medicinal ingredient.

Thus, under these interpretations, the patent did not include a claim for the dosage form as defined, and the Court upheld the decision of the Minister. The Court also refused to consider any expert evidence in its decision.
