`Re:
`
`Resonant Systems, Inc. d/b/a RevelHMI v. Apple Inc., 7:23-cv-00077 (W.D. Tex.)
`
`Counsel:
`
`Apple has filed an inter partes review (IPR) petition (IPR2024-00698) with the Patent Trial and
`Appeal Board (PTAB) to address the validity of claims 1-5 of U.S. Patent No. 8,093,767. The
`tables in attached Appendix A lists the grounds and references asserted in IPR2024-00698.
`
`I write to inform you that Apple hereby stipulates that if the PTAB authorizes petitioner to enter
`this stipulation into evidence in IPR2024-00698 and institutes the proceeding, Apple will not
`pursue in the above-captioned litigation the same invalidity grounds raised (or any grounds that
`could have been raised) in IPR2024-00698 for any claim of the patent. Sotera Wireless, Inc. v.
`Masimo Corp., IPR2020-01019, Pap. 12 at 13-20 (PTAB Dec. 1, 2020) (precedential)
`(“Sotera”).
`
`In so stipulating, Apple seeks to avoid multiple proceedings in different forums addressing the
`validity of the instituted claims based on the same grounds. Rather, through this stipulation,
`Apple expresses its intention to have only the PTAB address any grounds of invalidity of
`instituted claims that could have reasonably been raised in the IPR2024-00698 petition.
`
`Pursuant to Sotera, Apple reserves the right to assert grounds in the District Court proceedings
`based on system art, either alone, or in combination with other prior art.1 For the sake of clarity
`
`1 Apple notes that system art is not eligible for PTAB consideration in an IPR proceeding, and
`grounds based on system art either alone, or in combination with patent or printed publication
`prior art, could not have reasonably been raised before the PTAB in the IPR petitions. See 35
`U.S.C § 311(b). Further, discovery in the District Court proceedings is currently ongoing and
`Apple expects there to be additional materials and/or testimony relating to system art. For the
`
`APPLE 1048

`
`
`and to avoid any doubt, if the PTAB declines to institute IPR2024-00698, Apple reserves the
`right to assert any and all grounds of invalidity in the District Court proceedings against the ’767
`Patent.
`
`
