What do you mean? It's literally the legal mechanism by which Lovable Labs Incorporated can prevent this guy from calling his thing open-lovable.

Registering your trademark makes enforcement easier, but there's a reason both TM and R exist - unregistered trademarks still hold power.

Sure. But for a company with a lot of money at stake, filing a trademark application isn't a huge bar and makes winning the legal case a lot easier.

nope, fire your lawyer. you get a common law trademark by trading under a name. no need to register it. TM registration is just to streamline big corps chasing after lots of small abusers in a wackamole way, that’s all. if the abuse in question is as egregious as “I used their product name, barely modified, to market my own thing, which is not just in the same general market but a literal clone of their product” then a judge is not going to say “Ah but I see they didn’t send in a form to register their trademark, so yeah carry on with blatantly stealing their work lol”

I feel like "also trademark registration is not remotely relevant here" is a distracting statement then. Not necessarily wrong but easy for people to bikeshed over.

fair I retract “is not remotely relevant here” and offer “is not really relevant here”

Lovable is a $1.8 B valuation company with $75 M ARR. Using some thousands of dollars to defend that stake sounds reasonable.
