You are right and I am wrong, though there is a better quote to demonstrate my error. I read too quickly and still have not had time to go through it carefully. However, the SG does NOT say Amphastar v. Momenta was correctly decided:
The Momenta court additionally held that, for purposes of Section 271(e)(1), information may be deemed “submitted” to FDA if it is preserved in records that FDA regulations require a drug manufacturer to make available for inspection by FDA on request. See 686 F.3d at 1357. We express no view on the correctness of that conclusion or of the court of appeals' ultimate disposition of Momenta.
