Does a statutory bar preventing an inventor from commercially exploiting their invention apply to a patent?

The policy underlying this statutory bar "is to prevent an inventor from extending the period of patent monopoly by commercially exploiting the invention before applying for a patent." Del Mar Eng. Labs v. Physio-Tronics, 642 F.2d 1167, 1169 (9th Cir. 1981); see Pickering v. Holman, 459 F.2d 403, 406 (9th Cir. 1972).
