What WotC is trying to do now is say their new license invalidates the old license and magically everything under the OGL 1.0a is now licensed as OGL 1.1. The System Resource Document has a lot of non-trademarked content under the OGL 1.0a. Anyone could use those non-trademarked items under that license without any sort of issues. They don't have a trademark on the word "orc". They have IP covering a fictional "orc" species for a role playing system with some statistics and basic descriptions. This generic "orc" entity was licensed under the OGL 1.0a for anyone to use in their own games. Paizo and others based the "orc" species on the SRD.
