Though it's really more the name that's been patented at this point, and not the actual profile, right? Because there are several suppliers, WCP included, that sell a "GT2 compatible" profile. I don't know where the lines are drawn on how close other profiles can get before being in violation of the patents, but I'd say the "GT2 compatible" profiles are pretty close.
And yeah, none of Gates' load ratings are off of instantaneous loading or reversing loads.
