`Re:

`BillJCo, LLC v. Apple Inc.,
`Case No. 6:21-cv-00528 (W.D. Tex.)
`
`Dear Counsel:
`
`On behalf of Defendant Apple Inc. (“Defendant”) in the above-referenced case (“the Litigation”),
`we write regarding a petition for inter partes review (“IPR”) that Defendant intends to file with the Patent
`Trial and Appeal Board (“PTAB”) to address claims 1-3, 8, 20, 21, 23-27, 32, 44, 45, 47, and 48 of U.S.
`Patent No. 8,566,839 (the “Petition”) on November 30, 2021.
`
`We write to inform you that Defendant, as real party-in-interest (“RPI”) in the Petition, hereby
`stipulates that in the event the PTAB institutes an IPR based on the Petition, Defendant will not seek
`resolution in the Litigation of any ground of invalidity pursued in the instituted Petition.
`
`By so stipulating, Defendant seeks to avoid multiple proceedings addressing the validity of claims
`1-3, 8, 20, 21, 23-27, 32, 44, 45, 47, and 48 of U.S. Patent No. 8,566,839 based on the instituted grounds
`in the Petition. Defendant requests that the patentability of these claims over the grounds presented in the
`Petition to be addressed at the PTAB. For the sake of clarity and to avoid any doubt, if the PTAB declines
`to institute an IPR based on the Petition, Defendant reserves the right to pursue the non-instituted
`grounds from the denied Petition in this litigation. Additionally, even in the event of institution, Defendant
`reserves its right in the Litigation to rely on any prior art and prior art combinations other than the
`instituted grounds in the Petition.
`
`Best regards,
`
`Erik R. Fuehrer
