FC Finds Anticipated Formulation Patent Non-Obvious Since Same Prior Art Would Teach Away From Invention

In Merck & Co. Inc. v. Pharmascience Inc. (2010 FC 510), the Federal Court (FC) dismissed Merck & Co. Inc.'s (Merck) application to prohibit the Minister of Health from issuing a Notice of Compliance (NOC) to Pharmascience Inc. The FC found Canadian Patent No. 2,173,457 (the '457 patent) invalid on the basis of double patenting and anticipation. Significantly, the FC held that, despite its finding of anticipation, the '457 Patent was not obvious because prior art subsequent to the anticipating art would have discouraged any inquiry in to the relevant field of research.

Pharmascience had sought a NOC to market a generic version of the medicine finasteride, used in the treatment of male pattern baldness. Only dependent claim 5 of the '457 Patent remained in issue, and the FC summarized it as follows: "the use of finasteride for the preparation of a medicament adapted for oral administration useful for the treatment of male pattern baldness in a person and wherein the daily dosage is about 1.0mg."

FC interprets desired result claim language as unfulfilled promise in invalidating formulation patent for overbreadth and lack of utility

In Sanofi-Aventis Canada Inc. v. Ratiopharm Inc. (2010 FC 230), the Federal Court ("FC") denied Sanofi-Aventis Canada's (Sanofi) application to prohibit the Minister of Health from issuing a Notice of Compliance ("NOC") to Ratiopharm Inc. pursuant to section 6 of the Patented Medicines (Notice of Compliance) Regulations ("PMNOC Regulations"). The FC held Sanofi's Canadian Patent No. 2,177,772 was invalid for overbreadth, lack of utility and in any case was not infringed by the use of Ratiopharm's proposed composition.

Ratiopharm's NOC application was for irbesartan, a drug for treatment of cardiovascular ailments such as hypertension and heart failure. Canadian Patents 2,177,772 ("'772 patent") and 2,057,913 had been listed by Sanofi on the patent register in respect of irbesartan pursuant to section 4 of the PMNOC Regulations. Ratiopharm accepted that no NOC would issue prior to expiry of the '913 patent, so only the '772 patent remained for consideration. The '772 patent claims pharmaceutical compositions containing irbesartan, preferably in the form of tablets with a high relative amount of the active ingredient that allowed for a rapid dissolution and release.

NOC Prohibition Application for which appeals had not been exhausted was “pending”, allowed new regulations to attach stricter liability to Application’s eventual dismissal

In Apotex Inc. v. Merck & Co., Inc (2010 FC 287), the Federal Court of Canada (FC) held that Apotex is entitled to obtain compensation from Merck for having been kept out of the norfloxacin market for several years while the parties litigated Apotex's Notice of Compliance (NOC) application.

Apotex tried to market a generic version of norfloxacin in the early 1990s, a drug patented by Merck. Merck filed an order to prohibit Apotex from obtaining a NOC. The Supreme Court of Canada set aside the prohibition order on July 9, 1998 in Merck Frosst Canada v. Canada. Apotex sought relief under s.8 of the Patented Medicines (Notice of Compliance) Regulations, SOR/93-133 ("the 93 Regulations"), as amended by SOR/98-166 ("the '98 Regulations"), for delayed market entry caused by Merck's prohibition order application.

FC Holds Ice Skate Designer Infringed by inducement and procurement through Manufacturering partner unaware of patent

In Bauer Hockey Corp. v. Easton Sports Canada Inc. (2010 FC 361), the Federal Court ("FC") held Easton Sports Canada Inc. (Easton) infringed, and induced others to infringe, plaintiff Bauer's Canadian Patent No. 2302953 ("the '953 patent") claiming an improved skate having a one-piece quarter section. The FC found all skates manufactured by Easton using a claimed "F" pattern were infringing since these skates featured all of the essential elements claimed in the '953 patent design. (more...)

Canadian FCA Holds Patent Litigation Outcome Not Retroactive Basis for S8 PMNOCR Damages Action

In Apotex Inc. v. Syntex Pharmaceuticals International Inc. (2010 FCA 155), the Federal Court of Appeal ("FCA") affirmed the Federal Court's (FC) decision (2009 FC 494) dismissing Apotex's claim for damages under s.8 of the Patented Medicines (Notice of Compliance) Regulations ("PMNOCR"). The FCA held that s.8 of the PMNOCR does not apply where an innovator prevailed in PMNOCR prohibition proceedings but not in subsequent patent litigation, meaning generic manufacturers cannot retroactively apply a finding of invalidity to PMNOCR prohibition proceedings.

FCA confirms narrow interpretation of s.20(1) trade secret and confidentiality disclosure exceptions of Access to Information Act

In Canada (Minister of Health) v. Merck Frosst Canada Ltd. (2009 FCA 166), the Federal Court of Appeal ("FCA") reversed the Federal Court ("FC") and held the Minister of Health ("MOH") could disclose pharmaceutical regulatory approval records to a competitor access requestor under section 4(1) of the Access to Information Act ("the Act") without notice since none of the narrow exceptions listed in sections 20(1)(a)-(c) of the Act applied.

An access requestor requested records from the Minister of Health ("MOH") regarding Merck Frosst Canada's ("Merck Frosst") New Drug Submission ("NDS") for Singulair, a drug used in the treatment of asthma. After considering the section 20(1) exceptions, the MOH disclosed sections of the records to the requesting party without notice to Merck Frosst. The FC had held the MOH could not disclose information to an access requestor unless Merck Frosst was given notice to object since the records contained trade secrets, confidential technical information, or materials that could affect the financial or competitive position of a party.
