All that does is give Congress the jurisdiction to legislate it; that does NOT elevate intellectual property rights to the status of a "constitutional right" held by individuals as against private parties. That's a critical distinction.

For example, Congress could pass a law tomorrow completely rescinding the Copyright Act, or the DMCA. By contrast, it could NOT pass a law allowing for takings of property by a state actor in violation of the Fifth Amendment, because that would violate individuals' constitutional rights.
