`PLAINTIFF IMPLICIT, LLC’S DISCLOSURE OF INITIAL CLAIM CHARTS
`
`Pursuant to Protective Order [D.I. 16] ¶ 7(c) and the Court’s December 22, 2017 Order
`
`regarding scheduling, as well as paragraph 4(c) of the Delaware Default Standard for Discovery,
`
`Including Discovery of Electronically Stored Information (“ESI”), Plaintiff Implicit, LLC
`
`(“Implicit”) hereby makes the following disclosures of infringement contentions for United States
`
`Patent Nos. 7,391,791 (the “’791 patent”) and 8,942,252 (the “’252 patent”) (collectively, the
`
`“Asserted Patents”) regarding Defendant Sonos, Inc. (“Defendant”) and the offerings accused
`
`herein. Implicit’s investigation is ongoing, Implicit has received only core technical discovery
`
`from Defendants, and claim construction has yet to occur. Accordingly, these disclosures are
`
`based on information available to Implicit at this time, and are made without prejudice to Implicit’s
`
`right to supplement or amend these disclosures as Implicit obtains additional information, receives
`
`additional technical discovery from Defendant, and/or claims are construed. Implicit also reserves
`
`the right to find alternative literal and/or equivalent infringing elements in Defendant’s accused
`
`products.
`
`I.
`
`INITIAL CLAIM CHARTS
`
`Attached hereto at Exhibits A–B are Implicit’s initial claim charts relating to the Accused
`
`Instrumentalities. Any citations in these disclosures are exemplary and not exhaustive, as are the
`
`
`PAGE 1 OF 92
`
`SONOS EXHIBIT 1006
`IPR of U.S. Pat. No. 8,942,252
`
`

`examples provided of the ways in which the Accused Instrumentalities satisfy the elements of each
`
`Asserted Claim. Moreover, any and all citations or references to documentation should be
`
`understood to encompass any and all prior or later editions and versions that incorporate, describe,
`
`and/or relate to the same or similar functionality. The exemplary proof submitted in these
`
`disclosures is representative of the manner in which the Accused Instrumentalities infringe the
`
`Asserted Claims. The Accused Instrumentalities infringe the Asserted Claims as shown in these
`
`disclosures, regardless of the particular exemplary proof provided.
`
`Furthermore, by identifying in the attached claim charts exemplary evidence of where a
`
`limitation of an Asserted Claim may be found in an Accused Instrumentality, Implicit may address
`
`a range of potential claim constructions of such limitation, including constructions with which
`
`Implicit may disagree.
`
`Finally, Implicit has received only core technical discovery from Defendant, and has not
`
`yet received full discovery regarding the structure, function, or operation of the Accused
`
`Instrumentalities. Such discovery may provide additional details regarding the Accused
`
`Instrumentalities, and Implicit reserves the right to supplement these disclosures upon such
`
`discovery.
`
`Implicit expressly reserves its right to seek leave of Court to amend or supplement this
`
`disclosure after discovery from Defendant or as permitted under the applicable rules or by the
`
`Court. Implicit further reserves the right to supplement these disclosures to allege infringement
`
`under the doctrine of equivalents if it is found that the Accused Instrumentalities do not literally
`
`meet or practice a particular claim element for any of the claims.

`Exhibit B: Claim Chart Demonstrating That Defendant’s Sync-Capable Speakers Infringe Claims 1—3, 8, ll, 17 01' United States Patent
`No. 8,942,252 (the “’252 Patent”)
`
`As shown below, Sonos. Inc.’s (“Defendant’s”) sync-cable speaker products (including without limitation SonosNet, Play: 1, Playz3, Play:5,
`PlayBar, Sub Connect, and ConnectAmp) and/or other related hardware and/or sofiware products and services ofl'ered by Defendants (the
`“Accused Instrumentalities”) infringe claims 1—3, 8, ll, 17 of the ’252 Patent. By identifying exemplary evidence in this chart of where a
`limitation of an asserted claim may be found in an Accused Instrumentality, Plaintiff may address a range of potential claim constructions of such
`limitation, including constructions with which Plaintiff may disagree.
`
`Plaintiff has not yet had full discovery regarding the structure, flmction, or operation of the Accused Instrumentalities. Such discovery may
`provide additional details regarding the Accused Instrumentalities and Plaintiff reserves the right to supplement this chart upon such discovery.
`Plaintiff funher reserves the right to supplement this chart to allege infringement under the doctrine of equivalents if it is found that the accused
`instrumentalities do not literally meet or practice a particular claim element for any of the claims.
`
`For example, the Accused Instrumentalities perform a method for synchronizing audio playback among multiple speakers.
`
`To the extent this preamble is limiting. the Accused Instmmentalities perform a method.

`The method of the Accused Instrumentalities is performed wherein the first slave device is configured to smooth a rendering
`time differential that exists between the master rendering device and the first slave device in order to render a second content
`stream at the first slave device synchronously with the rendering of the first content stream at the master rendering device,
`wherein smoothing the rendering time differential includes calculations using the plurality of master rendering times.

`content to synchronize content playback.

`As set forth above, the Accused Instrumentalities perform the method of claim 1. The Accused Instrumentalities further
`perform this method wherein the first content stream is sent from a first source device to the master rendering device and the
`second content stream is sent to the first slave device from a difference source device.
`
`For example, each device in the Accused Instrumentalities receives content for rendering. The Group Coordinator (master)
`receives the content from the Music Source, and the ZoneGroup Members (slaves) receive the content from the Group
`Coordinator.

`
`The Accused Instrumentalities perform a method comprising receiving, at a slave device, a particular content stream.
`
`
`For example, each device in the Accused Instrumentalities receives content for rendering. The Group Coordinator (master)
`receives the content from the Music Source, and the ZoneGroup Members (slaves) receive the content from the Group
`Coordinator.
