The aspirin trademark was taken away as a punitive measure during or immediately after WWII. Lots of sites, including those written by people who should know better, get this wrong.
Nylon, so far as I can tell, never was a trademark.
"Shredded wheat" was ruled too generic to be trademarked.
"Zipper" was lost that way, though, as were "cellophane" and "thermos".
