The Pathfinder RPG is an OGL product. Doesn the OGL already allow me to make products using the Pathfinder RPG?
Yes and no. While the Open Game Content of the Pathfinder RPG is indeed available for use under the OGL, Section 7 of the OGL says “You agree not to indicate compatibility or co-adaptability with any Trademark or Registered Trademark in conjunction with a work containing Open Game Content except as expressly licensed in another, independent Agreement with the owner of such Trademark or Registered Trademark.” So while the OGL allows you to make compatible products, it forbids you from indicating compatibility using the terms “Pathfinder,” “Pathfinder Roleplaying Game,” or “Paizo,” since those are our trademarks. The Pathfinder Roleplaying Game Compatibility License serves as “another, independent Agreement” allowing you to use our Compatibility Logo to indicate compatibility with the Pathfinder Roleplaying Game.
