I am pretty sure that benelli stole the inertia system from someone else .
Browning had a long recoil system in the original A5 that Remington got the patent for and produced some guns built on the same principle, but as far as I know, the inertia system was all Benelli.
From Wiki, so take it with a grain of salt:. Inertia operation was developed by Paolo Benelli in the early 1980s and patented in 1986. Until 2012, all inertia-operated firearms either were made by Benelli, or used a design licensed from Benelli, such as the Franchi Affinity. Then the Browning Arms Company introduced the inertia-operated A5 (trademarked as Kinematic Drive) as successor to the recently discontinued, long-recoil operated Auto-5. Both the Benelli and Browning systems are based on a rotating locking bolt, similar to that used in many gas-operated firearms.
I should have said the general idea of recoil driven.
