`IPR2020-00459
`
`Petitioners stipulate that, if the IPR is instituted on the grounds presented in the IPR2020-00459 Petition (i.e., Hsu +
`Mozdzyn as applied to claims 1-4, 6-11, and 13-15; Hsu + Philipp as applied to claims 1-4, 6-11, and 13-15; Hsu + Chang
`as applied to claims 1-3, 7-10, and 14-15; and Hsu + Chang + Frey as applied to claims 4, 6, 11, and 13), then Petitioners
`will not pursue these same grounds in the parallel WDTex and NDCal district court litigations.
