Well, there are a couple of things.
Polytechnics rarely claim ownership of IP, and that is due, in part, to the kind of work they do. Usually the ownership of IP goes to intellectual contribution. For projects at SAIT, as a rule, the industry comes to SAIT with a problem they want solved, and then SAIT applies its capabilities. However, on the university side, typically the IP is the result of a multi-year, multi-person project, so the intellectual contributions come before the IP is generated through the project; just like for SAIT the intellectual contributions come from the industry side.
