what do you call intellectual creations?

It's called intellectual property. It's a legal phrase and carries with it copyright rights, royalties, etc., governed in the US by the US Copyright Act.

There is a huge body of US law on this that is very complex and requires lawyers who are certified specialist in copyright law to handle properly. If you don't want to protect your intellectual property, just say, "That's my creation." But watch out: Others will try to tell rip you off and profit from your ideas. And anything you invent is your intellectual property – songs, lyrics, artwork, software design. Anything. You can be sued for violating a person's intellectual property rights. It really is a serious matters. But those right have to be registered under the law. It's not just a legal term. Laypeople use it too. I kind of like the phrase, "legal portfolio" although the word has no legal significance. There's nothing vague about your question so it needs no clarification. (I'm a licensed attorney by the way.)
