`Re: Exela Pharma Sciences, LLC v. Eton Pharmaceuticals, Inc.,
`C.A. No. 20-365-MN
`
`Dear Judge Noreika:
`
`We write on behalf of Defendant Eton Pharmaceuticals, Inc. to update the Court on the
`status of proceedings pending before the Patent Trial and Appeal Board. Today, Eton’s petition
`requesting a post-grant review of claims 1–22 of Patent No. 10,478,453 B1 was denied.
`
`In view of this development, Eton respectfully withdraws its Motion to Stay Pending Post-
`Grant Proceedings (D.I. 32) without prejudice.
`
`If Your Honor has any questions concerning the foregoing, counsel is available at the
`Court’s convenience.
`
`Respectfully,
`
`/s/ Kelly E. Farnan
