`Re:
`
`GUI Global Products, Ltd D/B/A Gwee v. Apple Inc., Civil Action No. 4:20-cv-02652
`(S.D. Tex.)
`
`
`Dear Counsel:
`
`We write regarding a petition for inter partes review (IPR) being filed today with the Patent Trial and
`Appeal Board (PTAB) to address claims of U.S. Patent No. 10,259,021. The table below lists
`grounds asserted by Apple Inc. (“Apple”) in an IPR petition challenging claims of this patent, along
`with the implicated claims against which the grounds are asserted. We write to inform you that
`Apple hereby stipulates that in the event the PTAB institutes an inter partes review based on the
`petition being filed today in IPR2021-01290 and including the grounds listed in the table below
`against the corresponding claims listed in the table for those grounds (“Instituted Grounds”), Apple
`will not assert the Instituted Grounds against the corresponding claims listed in the table for those
`grounds in the above-captioned litigation (4:20-cv-02652).
`

`
`In so stipulating, Apple seeks to avoid multiple proceedings addressing the validity of these claims
`based on the Instituted Grounds. Rather, through this stipulation, Apple expresses its intention to
`have only the PTAB address the Instituted Grounds of invalidity of these claims. But, for the sake of
`clarity and to avoid any doubt, if the PTAB declines to institute any of the grounds identified herein

`
`
`based on the petition being filed today in IPR2021-01290, Apple reserves the right to assert such
`grounds in the above-captioned litigation (4:20-cv-02652). Additionally, even in the event of
`institution, Apple reserves its rights to continue to assert all grounds other than the Instituted
`Grounds.

`Sincerely,
`
