Just wondering if anyone knows if Tressyms are trademarked? –

I would assume tressym are, because they're specific to D&D and apparently created by Ed Greenwood. However, basic winged cats are common in cryptozoology and mythology, so they should not be. (I have no evidence or legal training for this opinion though.) — BadCatMan (talk) 03:31, September 1, 2018 (UTC)
Without asking WotC, or possibly Ed, directly, it would take around 4 months to find out for sure. -hashtalk 13:06, September 1, 2018 (UTC)
For v.3.5, only a limited list of monsters in the core three D&D books are considered product identity by Wizards of the Coast. These are:
But outside of the three core rulebooks, any monster introduced in a non-OGL book could be considered product identity of WotC, including tressym.
As BadCatMan, just have flying cats; name them something else.
