I think full audited accounting of research costs should be included in the patent filing and that the patent should end either after 20 years or until profits from the invention (including payments from other companies licencing the invention) match 10x the costs.

And the maximum payout on violating a patent should be the remaining profit to end the patent.

Differences between industries then look after themselves.

Oddly all patent creators realize that extended Cabo vacations are the best way to brainstorm, and private Jet flights help with collaboration. Obviously only affordable by wealthy companies.
