Where are all the Prior Art Users in Patent Cases?

For more than 200 years, patent law denied a patent to an inventor if someone else had invented the same invention first, whether or not they published the invention or sought a patent themselves. If you weren't the first to invent, you weren't entitled to a patent. That changed in 2011. For the past fourteen years, U.S. law has operated under a “first inventor to file” system, in which the law denies a patent only if someone else has filed their own patent application or published or disclosed the invention. That change leaves open the possibility that one person can invent something, use it in their business, and lose the right to use their own invention to someone who later invented and patented the same idea.
