United States law exempts reverse engineering for interoperability from the anti-circumvention rules, and the Ninth Circuit has held the intermediate copying it needs to be fair use (Sega v Accolade; Sony v Connectix); other courts have enforced a contract term against reverse engineering (Bowers v Baystate), so no finding is reported when a licence forbids it.
