`Re:
`
`Koss Corporation v. Apple Inc., Case No. 6:20-cv-00665
`
`Dear Ms. Ghavimi:
`
`We write regarding the petition for inter partes review (IPR) filed against the patent in suit, U.S.
`Patent No. 10,298,451, in the above-captioned litigation. We write to inform you that Apple Inc.
`hereby stipulates that if the Patent Trial and Appeal Board (PTAB) institutes this petition on the
`grounds presented, then Defendant, Apple Inc. (“Apple”), will not seek resolution within this
`litigation of any ground of invalidity that utilizes, as a primary reference, US Patent Application
`Publication No. 2007/0033197 (“Scherzer”), which is the primary reference in the grounds
`asserted in the IPR petition.
`
`Apple hereby further stipulates that if the PTAB institutes the petition filed on November 25, 2020
`(IPR2021-00255) on the grounds presented, which are directed against the same patent in suit,
`Apple will not seek resolution within the litigation of any ground of invalidity that utilizes, as a
`primary reference, US Patent No. 9,021,108 (“Brown”), which is the primary reference in the
`grounds asserted in the November 25, 2020 petition.
`
`In so stipulating, Apple seeks to avoid multiple proceedings addressing the validity of the patents
`in suit based on the same grounds. Rather, consistent with Congressional intent, Apple wishes
`the patentability of these patents over grounds in which Scherzer or Brown is the primary
`reference to be addressed at the Board. But, for the sake of clarity and to avoid any doubt, if the
`PTAB declines institution of Apple’s IPR petition relating to the ‘451 Patent, Apple reserves the
`right to pursue any such grounds in this litigation.
