Fry then utilized 3M's sanctioned "permitted

His 1997 suit against 3M was settled with a payment from 3M to Amron.
As part of the settlement, Amron agreed not to make future claims against the company unless the settlement agreement should be breached.
However, in 2016, he launched a further suit against 3M,
asserting that 3M was wrongly claiming to be the inventor, and seeking $400 million in damages. At a preliminary hearing, a
