The Canadian Intellectual Property Office has released guidance on “Computer-Implemented Inventions” as planned, in the wake of the Federal Court of Appeal decision in Amazon.  While “software” is technically not patentable, a “computer-implemented invention” is.  Such an invention could fall into one of several categories: a method (art, process or method of manufacture), machine (generally, a device that relies on a computer for its operation), or product (an article of manufacture). As before, computer programs, data structures and computer-generated signals alone are not patent-eligible.
