`
`Plaintiff,
`
`v.
`
`APPLE, INC.,
`
`Defendant.
`
`PLAINTIFF KOSS CORPORATION’S
`PRELIMINARY INFRINGEMENT CONTENTIONS
`
`Pursuant to this Court’s sample order governing patent cases,1 Plaintiff Koss Corporation
`
`(“Koss”) hereby provides its initial infringement contentions and accompanying claim charts
`
`(“Infringement Contentions”) to Defendant Apple, Inc. (“Apple” or “Defendant”).
`
`I.
`
`INTRODUCTION
`
`These Infringement Contentions are based in whole or in part on Koss’ current knowledge,
`
`its current understanding of the proper construction of the asserted claims of U.S. Patent 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”) (collectively, the “Koss
`
`Patents-in-Suit”), and its investigation to date. As fact discovery has not yet begun, and will not
`
`1 A schedule has yet to be entered in this case, however Koss provides these Initial Infringement
`Contentions consistent with the Default Schedule for this Court, which requires preliminary
`infringement contentions seven days before the case management conference.
`
`APPLE 1014 of IPR2021-00592
`
`KOSS-2037
`IPR2021-00680
`
`
`
`until after the Markman process under this Court’s default schedule, and as Defendant’s core
`
`technical documents are not scheduled to be produced until seven weeks after the CMC (which is
`
`deemed to have been held on November 13, 2020), these contentions are preliminary and Koss
`
`reserves its right to supplement upon the discovery of additional information.
`
`Further, given that the parties have not yet identified proposed terms for construction from
`
`the Koss Patents-in-Suit or provided proposed constructions for terms in the Koss Patents-in-Suit,
`
`and that the Court has not yet made any claim construction ruling in this action, Koss’ Infringement
`
`Contentions herein may be made in a variety of alternatives, and not all interpretations are intended
`
`to be consistent with each other and/or Koss’ other contentions in this action, and should not be
`
`otherwise construed. Koss’ Infringement Contentions do not constitute admissions or adoptions
`
`of any particular claim scope or construction. Koss’ Infringement Contentions may apply a variety
`
`of constructions in order to provide as full a disclosure as possible in advance of claim
`
`construction. Koss objects to any attempt to deduce claim construction positions from these
`
`Infringement Contentions.
`
`II.
`
`OVERVIEW OF THE INFRINGEMENT CONTENTIONS
`
`Koss contends certain Apple-branded and Apple-sold products and/or systems
`
`(collectively, “Accused Products”) infringe, directly and/or indirectly, either literally or under the
`
`doctrine of equivalents, the following claims of the ‘025 Patent, the ‘451 Patent, the ‘934 Patent,
`
`the ‘982 Patent and the ‘325 Patent:

`•
`
`Claims 1–56 of the ‘025 Patent;
`o Apple- and Beats- branded headphones, including Airpods, Airpods Pro,
`Powerbeats Pro, Powerbeats, Solo Pro, Solo3, Studio3, and any other product that
`functions in substantially the same manner as reflected in the attached charts, A-
`1–A-7.
`
`•
`
`Claims 1–7, 9–14, and 16–21 of the ‘451 Patent;

`
`•
`
`•
`
`•
`
`o Apple HomePod, and any other product that functions in substantially the same

`
`Claims 1–62 of the ‘934 Patent; and
`o Apple- and Beats- branded headphones, including Airpods, Airpods Pro,
`Powerbeats Pro, Powerbeats, Solo Pro, Solo3, Studio3, and any other product that

`
`The claim charts attached hereto as Exhibits A-1–E-1 respectively illustrate how the
`
`Accused Products satisfy the various elements of the asserted claims. Koss reserves the right to
`
`prove infringement by relying on documents and/or portions of documents other than those cited
`
`in Exhibits A-1–E-1, which are intended to be merely exemplary. Koss further reserves the right
`
`to supplement and/or amend these Infringement Contentions as appropriate and as permitted under
`
`this Court’s model schedule, including in response to any non-infringement or claim construction
`
`theory asserted by Defendant, in response to any claim construction order issued by the Court,
`
`following or in the course of fact or expert discovery, and/or upon the discovery of additional
`
`relevant evidence or information.
`
`Koss further reserves the right to prove infringement of any claim limitation under the
`
`doctrine of equivalents in the event that claim limitation is deemed not to be satisfied literally,
`
`whether due to claim construction or any other reason. Koss additionally reserves the right to
`
`supplement and/or amend its Infringement Contentions relating to indirect infringement.
