    Securing your brand identity requires a direct understanding of how Canadian trademark use rules govern market assets. You must establish documented proof of use Canada demands to protect your registrations against cancellation proceedings and rival disputes.

Exploring these statutory standards will help you build defensible portfolio procedures that keep your corporate assets safe from unexpected challenges.

    US-SUPREME-COURT-UPHOLDS.jpg

    Hot off the press... the US Supreme Court has decided i4i v. Microsoft. At a quick glance: s.282 of the US Patent Act requires a party alleging invalidity to show it by "clear and convincing" evidence. Also at a quick glance, this applies whether or not a piece of prior art was considered by the patent examiner.

  • Federal Court Overrules Supreme Court on Presumption of Validity

    Author: Alexander Stack Professional Corporation | Mar 07, 2011

    FEDERAL-COURT-OVERRULES-SUPREME-COURT-ON-PRESUMPTION-OF-VALIDITY.jpg

    Go read the post on this topic at Sufficient Description. It brings up an interesting topic - when courts review the validity of patents, does it have to comply with administrative law principles, or is it its own standard? Professor Siebrasse notes that Gauthier J. in Eli Lilly / cefaclor 2009 FC 991 essentially ruled that Supreme Court musing on this point was wrong, and agrees with Gauthier J.

    I always think its the beginning of the end of the line for an idea or concept when people start publicly making fun of it. So THIS ARTICLE in Slate Magazine about the Light and Warburton study on drug R&D costs is interesting. The article concludes:

    I don’t want to be a blogger that leaves negative comments unaddressed in the comments section, so I want to bring up two good comments to my post on the Light and Warburton article.

    First – actually, I shouldn’t have said anything about 11% being a high cost of capital. I certainly don’t keep track of what a reasonable cost is. It could be 20%, for all I know ;)

    Here is a link to a recent paper (pdf) by Donald Light and Rebecca Warburton titled "Demythologizing the high costs of pharmaceutical research", (BioSocieties, February 2011) which systematically critiques the estimates of pharmaceutical-related R&D costs routinely promoted by the research-based pharmaceutical companies.
