Just to be clear, Remington has several trademarks which are also used in SAAMI cartridges. Most recently being Blackout. (originally trademarked by AAC, now owned by RP)
Jet, PPC & Fireball being other notable examples. I'd have to check again, but I believe they also even trademarked "Express". (as in 7mm Express now known as the .280 remington)
The issue is not having a trademark, it's allowing unlicensed use of it for the purposes of ammo & barrel mfg as I understand it.
As of today both of AA's Grendel trademarks still show as "live" in the USPTO systems.
