`
`SUMMARY OF THE ’320 PATENT
`A. Brief Description
`The ’320 patent traces its lineage back to the disclosures of nine provisional
`
`applications filed between August 2011 and June 2012. Eight of those provisional
`
`applications are directed to embodiments of a “cleaning device” for view screens.
`
`(See APPLE-1011-APPLE-1019; APPLE-1001, 3:58-67.) The single remaining
`
`provisional application discloses embodiments of a “switching device” for
`
`activating/deactivating a magnetic switch of a portable electronic device. (See
`
`APPLE-1016, p.8.) This “switching device” provisional disclosure is what most
`
`closely resembles the ’320 patent’s claimed subject matter. (See, e.g., APPLE-1001,
`
`21:37-39.)
`
`The ’320 patent describes “a switching device for use with a portable
`
`electronic device having...at least one switch that can be activated or de-activated.”
`
`(APPLE-1001, 4:1-7; APPLE-1003, ¶¶21-25.) As one example, the switch of the
`
`portable electronic device can be activated/deactivated “by introducing a magnetic
`
`field to the at least one switch” via a magnet in the switching device. (Id.)
`
`Figure 24 (below) is a front view of a switching device 2401 and a portable
`
`electronic device 2402 discussed in the ’320 patent. (Id., 18:6-31.)

`
`
`
`The switching device 2401 “is selectively coupled to the front of the portable
`
`electronic device 2402”; and the electronic device 2402 includes a magnetic switch
`
`2404 that is activated/deactivated by the switching device 2401 . (Id., 18:7-18;
`
`17:55-59, 20:14-16.) In one embodiment, activation/deactivation of the switch
`
`causes the device to turn on/off. (Id., 17:55-59.)
`
`B. Claimed Subject Matter
`The ’320 patent’s claims are directed to a “system” comprising a “portable
`
`switching device coupled to a portable electronic device.” As recited in Claim 1,
`
`“the switching device includes a lid...[that] is recessed to configure to the electronic
`
`device,” such that “[a] first case [of the switching device] functions to protect [a]
`
`second case [of the electronic device].” Claim 1 also specifies, inter alia, that “the
`
`portable switching device is configured to activate, deactivate, or send into
`
`4
`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`hibernation the portable electronic device.” Claim 11 further narrows Claim 1 to a
`
`configuration where “the electronic device is wireless earplugs.”
`
`Claim 11 therefore implicates a protective case (switching device) for wireless
`
`earplugs (electronic device), where the case is configured to activate/deactivate the
`
`earplugs. But the ’320 patent does not describe, or even suggest, such an
`
`embodiment. And it appears Patent Owner only attempted to pursue claims to a case
`
`for earplugs after Petitioner’s Apple AirPods—the product line named in Patent
`
`Owner’s
`
`infringement allegations 1 —popularized “true wireless earbuds.”
`
`Regardless, the aspects of a protective earplugs case recited in the ’320 patent’s
`
`Challenged Claims were already known to those of skill in the pre-existing wireless
`
`headset art, as detailed below in Section V with reference to Gundlach, Lee, and
`
`other complementary publications.
`
`C.
`Prosecution History
`The ’320 patent was filed on November 27, 2019 as U.S. Appl. No.
`
`16/698,223 (“the ’223 application”). (APPLE-1002, p.92.) The ’223 application
`
`was accompanied by a Petition to Make Special Based on Age, which was duly
`
`granted. (Id., pp.84-85, 157.) With prioritized examination, the ’223 application
`
`received a first action just two months later on January 29, 2020. (Id., pp.17-24.)

`

`

`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`The action was a Notice of Allowance immediately endorsing the as-filed claims
`
`without substantive analysis. (Id.) The Examiner simply stated in conclusory
`
`fashion that: “Claims 1-13 are considered to be allowable because the prior art of
`
`record neither anticipates nor renders obvious the limitations of base claim 1.” (Id.,
`
`p.22.)
`
`III. LEVEL OF ORDINARY SKILL
`A person of ordinary skill in the art at the time of the ’320 patent (a
`
`“POSITA”) would have had at least a Bachelor’s degree in an academic area
`
`emphasizing electrical engineering, mechanical engineering, or a similar discipline,
`
`and at least two years of experience in the field working with electronic devices.
`
`(APPLE-1003, ¶20.) Superior education could compensate for a deficiency in work
`
`experience, and vice-versa. Id.
`
`IV. CLAIM CONSTRUCTION
`Based on the well-established principal that “claim terms need only be
`
`construed to the extent necessary to resolve the controversy,” no express
`
`constructions are required to institute review and find the Challenged Claims
`
`unpatentable. Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir.
`
`2011). As discussed throughout Section V, the Challenged Claims are obvious under
`
`any reasonable interpretation.

`V. THE CHALLENGED CLAIMS ARE UNPATENTABLE
`A. GROUND 1A—Gundlach and Lee render claims 1, 2, 8, 9,
`and 11 obvious.
`1. Overview of Gundlach
`Gundlach discloses a variety of expandable/collapsible wireless headset
`
`embodiments having “relatively thin shape[s] [that] may allow the headset[s] to be
`
`stored and charged in a portable cradle….” (APPLE-1005, [0003], [0005], [0055-
`
`0056]; see also APPLE-1003, ¶¶26-30.)
`
`Gundlach describes one example of a wireless headset with reference to
`
`Figure 1 (below). (See APPLE-1005, [0058].) Gundlach’s wireless headset 100
`
`includes a housing 101 for supporting functional components, including a
`
`microphone 102 and a speaker 105 directing sound through an earpiece 104. (Id.)
`
`
`
`7
`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`The housing 101 further supports “a transceiver 106 for sending and receiving
`
`information 108 from a host device 110, such as a computer, a cell phone or a media
`
`player,” and a power source 111 in the form of a rechargeable battery. (Id.)
`
`Gundlach’s Figures 2a-2d (below) provide perspective, front, bottom, and top
`
`views of a wireless headset 200, highlighting its compact design.
`
`Figures 3a-3b (below) illustrate expanded and collapsed states of Gundlach’s
`
`wireless headset 300. (APPLE-1005, [0055-0056], [0060].)

`
`
`

`

`IPR of U.S. Patent No. 10,589,320
`Gundlach broadly notes that the wireless headset can be “stored and charged
`
`in a portable cradle,” such as “a holder, clip, case or card.” (APPLE-1005, [0056].)
`
`Gundlach discloses a variety of cradles with embedded magnets and/or mechanical
`
`elements for retaining a wireless headset. (E.g., id., [0068], [0073], [0075], Figures
`
`10a-19b.) As one example, in Figures 18a-18b (below) the “portable cradle” is a
`
`clamshell case 1860 that retains the wireless headset 1800 within a contoured recess
`
`1846 in one of two opposing lids. (Id., [0080].)

`
`2. Overview of Lee
`Similar to Gundlach, Lee “relates to wireless battery charging of wireless
`
`headphones/headsets.” (APPLE-1006, 3:21-22, 1:14-29; APPLE-1003, ¶¶31-34.)
`
`While Gundlach was more concerned with the physical form of the wireless headset
`
`and charging case, Lee sought improvements relating to energy transfer. (Id., 1:62-
`
`2:2, 3:17-20.)
`
`Figures 5 and 18 (below) illustrate Lee’s solution: “[t]he power source 200
`
`provides energy via a conductive means 202 to a power adapter 201,” and “[t]he
`
`power adapter 201 provides power to the wireless headphone/headset apparatus 204
`
`via non-conductive means 203, typically inductive coupling.” (APPLE-1006, 3:32-
`
`37.) Notably, and consistent with Gundlach, Lee’s “power adapter” is illustrated in
`
`certain embodiments as a protective charging case. (Id., 6:31-38.)
`
`Lee provides more detail about its inductive charging solution with reference
`
`to Figure 12 (below). As shown, energy transferred to the headset apparatus 460 is
`
`
`
`10
`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`received by an energy collection element 465 via inductive coupling 461. (APPLE-
`
`1006, 4:51-57.) Energy received by collection element 465 is converted from AC
`
`voltage to DC voltage by rectifier 464 and filtered using an energy storage capacitor
`
`469 en route to a battery charging circuit 462 that provides the proper voltage to the
`
`battery 463. (Id., 4:59-5:66.)
`
`Recognizing that “audio distortion” may occur when the energy collection
`
`element 465, a speaker transducer coil, is connected to the above-discussed charging
`
`components, Lee provides an isolation switch 470. (APPLE-1006, 5:12-26.)
`
`Closing switch 470 places the headset apparatus 460 in a “charging mode” and
`
`
`
`11
`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`opening switch 470 places headset apparatus 460 in a “non-charging mode.” (Id.)
`
`Operation of switch 470 occurs either automatically when the power adapter is
`
`“sense[d]” near the headset apparatus 460, or in response to a wireless control signal
`
`from the power adapter. (Id., 5:30-40.)
`
`3.
`The Gundlach-Lee Combination
`Gundlach teaches a variety of embodiments featuring “a wireless mono or
`
`stereo headset” that is “stored and charged” in a “portable cradle.” (APPLE-1005,
`
`[0055].) But beyond noting that “[t]he case may contain...charging circuitry” and
`
`“electrical contacts,” Gundlach is largely unconcerned with implementation details
`
`of charging. (APPLE-1005, [0069], [0073], [0079]-[0080]; APPLE-1003, ¶35.) For
`
`example, although a POSITA would have found it obvious that Gundlach’s wireless
`
`headset includes “an electronic circuit that is responsive to the” portable cradle
`
`([1d]), Gundlach does not expressly describe the manner in which the headset’s
`
`“charging circuitry” responds when placed in the cradle for charging.
`
`A POSITA considering Gundlach, and noting its limited disclosure on
`
`charging, would have seen a need for elaboration and description of design options.
`
`(APPLE-1003, ¶35.) In seeking a supplement to Gundlach, the POSITA would have
`
`encountered Lee’s disclosure on charging in the familiar context of wireless
`
`headsets. (Id.)
`
`
`
`12
`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`Like Gundlach, Lee also discloses multiple embodiments for storing and
`
`charging a wireless headset in a protective case. (E.g., APPLE-1006, 3:32-37, 3:50-
`
`62, 6:31-38.) Although otherwise similar, one notable distinction between Gundlach
`
`and Lee is the technology used to effect charging. (APPLE-1003, ¶¶36-37.) The
`
`embodiments described in Gundlach include electrical contacts for conductive
`
`charging, while Lee’s charging case and headset employ inductive charging.
`
`(Compare APPLE-1005, [0066], [0069], [0073], [0079] with APPLE-1006, 3:32-37,
`
`3:50-62, 4:11-5:40.) A POSITA motivated to combine Gundlach and Lee (for at
`
`least the reasons below) would have done so by exchanging the conductive charging
`
`components hinted at by Gundlach with the more thoroughly explained inductive
`
`charging components of Lee. (APPLE-1003, ¶37.) These modifications would have
`
`been well within a POSITA’s skill. (Id., ¶38.)
`
`
`
`13
`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`The resulting Gundlach-Lee combination (diagrammed above 2 ) would
`
`facilitate inductive charging in the manner described by Lee. (APPLE-1003, ¶39.)
`
`As discussed (see Section V.A.2), when the isolation switch (Lee’s element 470) is
`
`closed, the battery charging circuit (Lee’s element 462) in the headset is activated to
`
`provide energy to the battery at the proper voltage for charging (Lee’s element 463).
`
`(Id.)
`
`A POSITA would have been amply motivated to pursue the above-discussed
`
`Gundlach-Lee combination. First, a POSITA would have recognized inductive
`
`charging as a suitable alternative to conductive charging that was known to produce
`
`similar results. (APPLE-1003, ¶¶40-41 (citing APPLE-1020; APPLE-1021,
`
`APPLE-1022).) The routine design process of a POSITA developing a headset and
`
`charging case in view of Gundlach would have, therefore, contemplated an inductive
`
`charging solution like Lee’s. (Id.)
`
`Second, given Gundlach and Lee’s clear similarities—i.e., both disclose a
`
`charging case for a wireless headset—a POSITA would have appreciated that the
`
`benefits of inductive charging disclosed by Lee, such as enhanced reliability, would
`
`apply to Gundlach’s embodiments. (APPLE-1003, ¶¶42-43 (citing APPLE-1006,
`
`
`2 Petitioner provides this visual aid for the Board’s convenience. In doing so,
`
`Petitioner does not intend to represent a bodily incorporation of Lee with Gundlach.
`
`14
`
`

`

`Attorney Docket No. 50095-0031IP1
`IPR of U.S. Patent No. 10,589,320
`
`1:62-2:2; APPLE-1023).)
`
`Third, a POSITA would have appreciated that Lee’s inductive charging
`
`solution was consistent with Gundlach’s goal of providing a compact form factor.
`
`(APPLE-1003, ¶44 (citing APPLE-1005, [0056-0057] (noting the headset’s
`
`“relatively thin shape”)).) Lee, for example, utilized a single coil for both audio
`
`transmission and inductive charging, which avoided unnecessary bulk and achieved
`
`“a reduction of size and weight.” (Id. (citing APPLE-1006, 2:62-66, 4:55-57, Figure
`
`12; APPLE-1029).)
`
`Fourth, a POSITA would have viewed Lee’s inductive charging solution as
`
`providing yet another advantage to Gundlach’s wireless headset—i.e., charger
`
`interoperability absent the added bulk of a standardized connection (e.g., USB).
`
`(APPLE-1003, ¶45 (citing APPLE-1005, [0066]; APPLE-1006, Figures 16, 18, 19).)
`
`By employing Lee’s space-efficient dual-purpose coil for inductive charging in the
`
`context of Gundlach, the wireless headset could be recharged using other types of
`
`chargers (e.g., a charging pad) beyond the clamshell case without the size penalty of
`
`additional hardware. (Id.)
`
`This predictable combination of Gundlach and Lee renders obvious each and
`
`every feat
