I think a solid example is Jaleel White/Purple Urkle/"It's Purpl" strain/brand. It doesn't mean you can't sell something crossed with Purple Urkle, or hell even make F2s or S1s or whatever you want and reselling those even as Purple Urkle, but you can't use his likeness or anything infringing on his trademark(s).
Here's another example:

I just got some testers which have male Top Dawg lineage; if i were so inclined or smart enough/had enough time knowledge etc, what's to stop me from profitting off of these and never so much as tipping my brim to not only JJNYC, but also Gromer(?) (Carl's Shoes) OR most importantly the gracious "chucker" who gave me these?? I would never do that, but the more I read about breeders and lineages and this-n-that, a lot of foundations are built upon such behavior, loosely speaking. I dunno, it's just hard sometimes to sift the b.s. and ultimately I just look for what i like/can afford/can obtain.
