Jeffrey Proehl, for the Sioux Falls Business Journal via Argus Journal; Inventor's Corner: What happens when someone infringes a patent?
"Jeffrey Proehl is a registered patent attorney with Woods, Fuller, Shultz & Smith P.C. in Sioux Falls.
Although the U.S. Patent and Trademark Office grants patents, the U.S. government does not enforce patents against infringers. When a patent owner becomes aware someone without authorization is “making, using, selling, offering for sale, or importing” a product that infringes the owner’s patent, the owner has the option to enforce the patent."
