Patentability of dosage requirements: towards an easing of requirements in canada

By Lazarina CHOISNEL and Cécile PUECH, French & European Patent Attorneys
In contrast to that of the United States, Canadian patent law excludes therapeutic methods from patentability on the grounds that physicians should not be hampered in their practice of medicine. However, as in many countries that also have this exclusion, it is possible to protect the use of a compound or a composition for therapeutic purposes in Canada, provided that an appropriate claim format is used.

By Cécile PUECH, French & European Patent Attorney
While European case law has long since limited the cases in which an antibody can be claimed solely by functional features, U.S. case law has recently moved in the same direction. Following two decisions by the U.S. Court of Appeals for the Federal Circuit (Federal Circuit) involving Amgen and Sanofi, it could be argued that the U.S. case law has taken a more drastically limited view on claiming antibody functional features.
