`
`

`

`Pursuant to the November 25, 2020, Agreed Scheduling Order (Dkt. No. 29), Defendant
`
`Apple Inc. (“Apple”) provides the following contentions regarding the invalidity of U.S. Pat. Nos.
`
`10,206,025 (“the ’025 Patent”); 10,298,451 (“the ’451 Patent”); 10,469,934 (“the ’934 Patent”);
`
`10,491,982 (“the ’982 Patent”); and 10,506,325 (“the ’325 Patent”). Apple’s Invalidity
`
`Contentions (“Invalidity Contentions”) address the patents and asserted claims identified in Koss’
`
`Infringement Contentions of November 6, 2020.
`
`Apple’s Invalidity Contentions reflect its knowledge and contentions as of this date in the
`
`present action. The disclosures are based upon the knowledge, information and/or belief presently
`
`available to Apple. Apple’s search for prior art is ongoing, and Apple reserves the right to modify
`
`and supplement its Invalidity Contentions, as permitted by this Court’s Order Governing
`
`Proceedings, any Court order, and any other applicable rules and statutes, including in the event
`
`that additional prior art is identified during the course of discovery and/or in response to any
`
`amendment by Koss of its Infringement Contentions. In particular, Apple reserves its right to serve
`
`Final Invalidity Contentions at the time directed by the Agreed Scheduling Order.
`
`Each of the asserted claims of the ’025, ’451, ’934, ’982, and ’325 Patents is anticipated
`
`by and/or obvious in view of the items of prior art identified in Exhibits A1–E8 hereto, alone or in
`
`combination, as set forth in those Exhibits. Much of the art identified in the attached Exhibits
`
`reflect common knowledge and the state of the art at the time of filing of the ’025, ’451, ’934,
`
`’982, and ’325 Patents. Specific examples of anticipation and obviousness, along with the
`
`motivation to combine the selected prior art, are set forth below.
`
`I.
`
`
`
`IDENTIFICATION OF PRIOR ART
`
`A.
`
`Prior Art Patents and Applications
`
`Apple contends that the prior art patents and applications listed below anticipate and/or
`
`render obvious the asserted claims of the ’025, ’934, ’982, and ’325 Patents (collectively, the
`
`Page 2 of 44
`
`KOSS-2013
`IPR2021-00686
`
`

`

`“Headphone Patents”) under pre-AIA 35 U.S.C. §§ 102(a), (b), and/or (e) and/or 35 U.S.C. § 103,
`
`or provide information relating to the background state of the art at the time the Headphone Patents
`
`were allegedly conceived. In addition, Apple refers to the prior art patents and applications cited
`
`in any petition filed before the Patent Trial And Appeal Board relating to any of Koss’ Headphone
`
`Patents (or any patent claiming common priority therewith), including, IPR2021-00305 and
`
`IPR2021-00381, to the extent they are not listed below.

`To the extent that that any of the patents and applications listed above describe systems,
`
`apparatuses, or methods that were implemented, built, used, or reduced to tangible form, Apple
`
`reserves the right to rely upon such systems, apparatuses, or methods as independent bases for
`
`prior art. Citations to disclosures within these prior art patents and applications should be construed
`
`to also comprise citations to the corresponding functionality in the relevant system, apparatus, or
`
`method.
`
`Apple contends that the prior art patents and applications listed below anticipate and/or
`
`render obvious the asserted claims of ’451 Patent under pre-AIA 35 U.S.C. §§ 102(a), (b), and/or
`
`(e) and/or 35 U.S.C. § 103, or provide information relating to the background state of the art at the
`
`time the ’451 Patent was allegedly conceived. In addition, Apple refers to the prior art patents and
`
`applications cited in any petition filed before the Patent Trial And Appeal Board relating to the
`
`’451 Patent, including IPR2021-00255, to the extent they are not listed below.
