Rappel: Prometheus Laboratories v. Mayo (brevet-US)

vendredi 21 octobre 2011

Pour les praticiens en PI

Dans la cause PROMETHEUS LABORATORIES, INC. v. MAYO COLLABORATIVE SERVICES (628 F.3d 1347 (2010)) la Cour d’Appel fédérale des US se penche sur la question de la matière brevetable.

Selon la cour, la méthode de traitement brevetée satisfait le test « machine-or-transformation ». Bien que la cour reconnait qu’il ne s’agit pas d’un test exclusif dans un contexte Post Bilski , selon ellece test fournie d’importantes indices quand au caractère brevetable du sujet en question:

« to methods of treatment, which are always transformative when one of a defined group of drugs is administered to the body to ameliorate the effects of an undesired condition. »

« … »determining » step to be transformative because it involves « [s]ome form of manipulation, such as the high pressure liquid chromatography method specified in several of the asserted dependent claims or some other modification of the substances to be measured, [which] is necessary to extract the metabolites from a bodily sample and determine their concentration.« 

Concernant les « mental steps »:

« A subsequent mental step does not, by itself, negate the transformative nature of prior steps. »

Reminder: No exclusions in Canada for « Business Method Patents »

“[61] There is no basis for the Commissioner’s assumption that there is a “tradition” of excluding

business methods from patentability in Canada. The only Canadian jurisprudence cited was made as

obiter and in dissent by Arbour J. in Schmeiser.”

“[69] The Commissioner’s decision introduced one more novel and unnecessary requirement for

patentability into the Canadian patent regime: the technical or technological requirement. She also

suggests that “new and useful knowledge” must be “scientific or technological” in order to

constitute a patentable art. Thus, according to this reasoning, one must now assess whether an

invention : and specifically what has been added to human knowledge : is technological in nature.”

“[70] In fairness, in this instance the Commissioner does glean some of her rationale from the

language in the Patent Rules and Canadian jurisprudence, but this does not translate into an

endorsement or imposition of a “technical test”. There is no reference to such a test in the Canadian

jurisprudence (or none was advanced in this Court). It was not within the Commissioner’s

jurisdiction to introduce one. Once again, the Commissioner’s heavy reliance on the “technical

contribution approach” as discussed in the UK did not correspond with the reality of our Patent Act

or recognize the range of opinions as to its application and appropriateness…”

With regards to the specific Amazon patent application, Amazon’s invention qualified under s. 2 because (1) the system claims require a machine as an essential element of the invention and (2) the method claims are “put the into action through the use of cookies, computers, the internet and the customer’s own action” and results in a “physical effect” on those elements.
