`Re: Masimo Corporation et al. v. Apple Inc., Case No. 8:20-cv-00048 (C.D. Cal.)
`
`Dear Counsel:
`
`We write regarding petitions for inter partes review (IPR) being filed with the Patent Trial
`and Appeal Board (PTAB) to address claims of U.S. Patent No. 10,588,554. The table below
`lists grounds asserted by Apple in IPR petitions 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).

`Grounds
`Mendelson-799 in view of Ohsaki,
`Schulz, and Mendelson-2006
`Aizawa in view of Inokawa, Ohsaki,
`and Mendelson-2006
`Aizawa in view of Inokawa, Ohsaki,
`Mendelson-2006, and Bergey
`
`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
`institution, Apple reserves its rights to continue to assert all grounds other than Instituted
`Grounds.
`
`Sincerely,
`
