Patented Medicine Prices Review Board news

Teva Neuroscience ordered to pay $2.8M to offset excess revenues for COPAXONE syringes. In a 2008 decision, the Board had ordered that Teva Neuroscience repay approximately $2.4M to offset excess revenues for Teva Neuroscience's COPAXONE (glatiramer acetate) syringes. As reported in the December 2009 issue of Rx IP Update, the Federal Court set aside the Board's decision and returned the matter to the Board for redetermination (2009 FC 1155). On February 23, 2012, the Board issued its decision and ordered Teva Neuroscience to repay approximately $2.8M to offset excess revenues. The Board recognized that COPAXONE syringes became the lowest priced medicine relative to its therapeutic comparators once Teva Neuroscience removed another COPAXONE product from the market and considered this factor in formulating the remedy. However, the Board held that in the period following 2004, the price increase (for example, 7.23% in 2004 and 5.96% in 2005) exceeded the protection that Parliament had provided and held that this both sudden and significant price increase should be a factor considered in the remedy. Taking into account these two factors, the Board departed from its Consumer Price Index Adjustment Methodology outlined in the Board's guidelines and ordered Teva Neuroscience to reimburse revenues of approximately $2.8M. Teva Neuroscience has applied for judicial review.

Recent Court decisions

Patented Medicines (Notice of Compliance) Regulations

Court of Appeal affirms pleading amendments relying on factual findings by a foreign court. On February 29, 2012, the Court of Appeal dismissed Apotex's appeal from a judgment of the Federal Court, which dismissed Apotex's appeal from a Prothonotary's Order granting leave to AstraZeneca to amend its pleading to assert that Apotex is estopped from litigating certain factual findings regarding Apotex's omeprazole product (AstraZeneca's LOSEC) made by a United States District Court. The Court of Appeal concluded that it is not plain and obvious that the factual findings are inextricably bound or related to the foreign court's construction of the claims and that the disputed amendments cannot succeed in law.

Apotex Inc. v. AstraZeneca Canada Inc. et al., February 29, 2012.
Federal Court of Appeal decision — 2012 FCA 68.
Federal Court decision — 2011 FC 598.

CIRA decisions

BCICAC orders flovent.ca transferred to Glaxo. On March 12, 2012, the British Columbia International Commercial Arbitration Centre ("BCICAC") ordered the domain name flovent.ca to be transferred from the registrant to the complainant, Glaxo. The BCICAC found that the domain name is confusingly similar to Glaxo's registered trademark FLOVENT, the registrant had registered the domain name in bad faith, and the registrant had no legitimate interest in the domain name.
