How is that not greedy and selfish?
It's that "rightfully yours" bit that really bothers me. Where does that come from and why is it so obviously rightfully yours? It takes some gumption to assume you're in the right. This land is rightfully mine because I bought it from someone else who genocided a people, but okay great, it's rightfully mine, I feel super great about it.
The one's filing them and demanding what's rightfully theirs are selfish, the one's not filing patents are less selfish.
