It seems like a slightly weaker patent system where the holder only retains the right to share in the profits on a piece of technology would solve most of the problems. Like, once you publish a patent, anyone who uses it needs to pay you a meaningful portion of profit they derive from using it. The patent holder still has most of the incentive to use it, but R&D on the patent would be fully open and incur no fee. Third parties could sell improvements back to the patent holder or file their own patents on the improvements.
