CIPO’s new guidelines on patentable subject matter

The Canadian Intellectual Property Office (CIPO) recently released new guidelines on patentable subject matter and a set of examples applying the new guidelines to computer-implemented inventions, medical diagnostic methods, and medical uses.

Notably, these new guidelines supersede current guidance within the Manual of Patent Office Practice for determining patentable subject matter and introduce a new three-step process for determining patentable subject matter. The steps are:

  1. Identify “essential elements” of a claim;
  2. Determine an “actual invention” of the claim; and
  3. Determine if the “actual invention” of the claim has physicality

Smart & Biggar has a fantastic explainer on the new guidelines, including a breakdown of the new three-step process for determining patentable subject matter. Go here to read the explainer.
