They simply can't profit on their new innovation without licensing the patent. However what they can do with their new innovation is patent the innovation itself. This newly patented innovation prevents the original patent holder from profiting off of the new innovation, and thus incentivizes the original patent holder to license their patent to the new patent holder (or vice versa).
