Regarding copyright

Hello Rabbi Michael,
I heard you say in one of the recorded lessons that there can be ownership of ideas, and you based your statement on the fact that ownership of abstract things like smell, sound, light, etc. is subordinate to ownership of the tangible thing of which the abstract thing is a characteristic.

I recently read a halachah in the Rambam that if the shofar is stolen, it is permissible to perform the obligatory ritual on Rosh Hashanah because the sound is not stolen. But the sound is something abstract that is attributed to the shofar (the tangible thing). And if we say that the abstract follows the tangible, then, as it were, the sound of the shofar is also stolen.
