`Re:
`
`StratosAudio, Inc. v. Hyundai Motor America, - Case No. 6:20-cv-01125-ADA
`
`Dear Michael:
`
`We write to inform you that Hyundai Motor America (“HMA”) hereby stipulates that if the PTAB
`institutes inter partes review for HMA’s concurrently filed IPR petition challenging U.S. Patent
`8,688,028 (the “’028 Patent”), then HMA will not pursue invalidity against StratosAudio’s
`presently asserted claims of the ’028 Patent in the District Court proceeding captioned above
`using any obviousness ground which includes the primary references in that petition, referred to
`therein as “Curtin” and “Alwadish.” HMA reserves the right to present invalidity in the District
`Court proceeding on other bases.
`
`To be clear, this stipulation does not encompass any arguments regarding the proper priority
`date or dates of alleged invention of the ’028 Patent claims. Accordingly, HMA reserves the
`right to make arguments regarding the priority date of the ’028 Patent. This stipulation does not
`apply to any claims other than the ’028 Patent claims challenged in the above-captioned IPR
`that are also presently asserted in District Court, nor does it apply to any claims of any other
`patent. Additionally, the primary references identified above may be included in Hyundai’s
`invalidity contentions to preserve its rights in the event that, for example, the above-captioned
`IPR does not go forward.
`
`Sincerely,
`
`
`
