`Re: Masimo Corporation et al. v. Apple Inc., Case No. 8:20-cv-00048 (C.D. Cal.)
`
`Dear Counsel:
`
`We write regarding a petition for inter partes review (IPR) being filed with the Patent Trial
`and Appeal Board (PTAB) to address claims of U.S. Patent No. 10,709,366. The table below
`lists grounds asserted by Apple in an IPR petition challenging claims of this patent, along
`with the implicated claims against which each ground is asserted. We write to inform you
`that Apple hereby stipulates that in the event the PTAB institutes an inter partes review
`including a ground listed in the table against the corresponding claims listed in the table for
`that ground (“Instituted Ground”), Apple will not assert that Instituted Ground against the
`corresponding claims listed in the table for that ground in the above captioned litigation
`(8:20-cv-00048).
`
`Patent No. Proceeding No.

`Aizawa in view of Mendelson-2003,
`Ohsaki, Goldsmith, and Sherman
`
`In so stipulating, Apple seeks to avoid multiple proceedings addressing the validity of these
`claims based on the Instituted Grounds. Rather, consistent with Congressional intent,
`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, Apple reserves
`the right to assert such grounds in this litigation. Additionally, even in the event of

`Grounds.
