Maximize Your Patent Portfolio Using Helferich – Style Claims

Patent owners often obtain patents to protect products, as well as complementary products or use cases associated with those products. However, when selling or licensing the patented products, a patent owner may inadvertently extinguish potential revenue streams associated with the complementary use cases due to the doctrine of patent exhaustion. 

Patent exhaustion follows the basic idea that if a company sells or licenses a patented product to a buyer, the company cannot sue the buyer (or a third party that the buyer provides the patented product to under the license) for patent infringement for using the product.
