This question touches on the OGL, but talks more about WotC (dnd3.5e) and CC vs. OGL conflict.
Some places I've looked into regarding this:
Paizo Open Game License page. Specifically this (emphasis mine):
The following items are hereby identified as Product Identity, as defined in the Open Game License 1.0a, Section 1(e), and are not Open Content: All trademarks, registered trademarks, proper names (characters, deities, etc.), dialogue, plots, storylines, locations, characters, artworks, and trade dress. (Elements that have previously been designated as Open Game Content are not included in this declaration.)
Except for material designated as Product Identity (see above), the game mechanics of this Paizo Publishing game product are Open Game Content, as defined in the Open Game License version 1.0a Section 1(d). No portion of this work other than the material designated as Open Game Content may be reproduced in any form without written permission.
I am not a lawyer, so I can't be sure, but I believe this means I can copy text from the Pathfinder published materials.
It's possible that I can until it's taken down by action from Paizo, but I'd like to never reach that point if such a point exists (and I can always safely reference d20PFSRD, I suppose).
This is my first meta question, so let me know if it's not quite in the right format (or edit it into oblivion).
