While a patent or copyright is held by a company or a person, no one else can use that product or copyrighted material (also known as intellectual property) without the permission of the patent/copyright holder which usually involves some kind of compensation. If someone wants to use one of these products or materials, and can't come to an agreement with the patent/copyright holder, then they are motivated to produce a variation or an improvement on it and get their own patent/copyright for themselves. New products and materials are developed all the time to compete with an existing patent or copyright.
