In the U.S., the inventor must be a natural person. The owner, however, is often a corporation (e.g., when an employee invents something in the scope of employment). In that case the owner corporation applies for the patent in the inventor's name, but it will own all the rights in the patent. The inventor usually signs an inventor declaration. In other countries the inventor can be a corporation. There are some cases where this matters (e.g., disputes over inventorship or ownership of the invention of an employee), but in most cases it probably doesn't matter.
