Intellectual property is something unique that you physically create. An idea alone is not intellectual property. For example, an idea for a book doesn’t count, but the words you’ve written do

"Intellectual property is something unique that you physically create. An idea alone is not intellectual property. For example, an idea for a book doesn’t count, but the words you’ve written do" (from the UK government website). This is a universal principle: having ideas is not protectable (are you quite sure that nobody else has had the same idea, or ever will?)
So unless you have put some work into producing a specific implementation, your idea can be used by anybody who thinks of it.
