Nope. That's how intellectual "property" law works: some person comes up with something cool, then a company gets the rights to it and prevents anyone from doing anything with the concept, even if the company itself isn't doing anything with the concept; not even the original creator can do anything with the concept without the company's permission.
This is a major issue in patents (intellectual "property" that grants exclusive rights to an invention), where companies ('patent trolls') exist just to buy up rights, do absolutely nothing with them, then sue other companies when they create something that resembles the stuff they have patents for, often without knowing the patent troll even had any patents resembling the idea.
In video games you can often see this happening with large corporations buying rights from defunct publishers. For instance, Sony holds the right to most Psygnosis games, which is why we never get any new Lemmings games (or even Lemmings ports to modern systems) because they can't legally be made without Sony's permission, even though they're not doing anything with the rights. This situation will last until 2086, when the copyright to the first Lemmings game finally expires.
People insist this helps creativity and inspires people to create things.
