Other way around. Pathfinder came first. WotC was mad that they couldn't monetize it so they made the 4e license more restrictive.
D&D 4e's core rulebook released in June of 2008.
Pathfinder 1e's core rulebook released in August of 2009.

Now, I'm not the best with calendars, but I'm pretty sure 4e existed a full year before Pathfinder released.
