“But before describing the embodiments cited by Patent Owner, the Specification plainly states: “Any terms not expressly defined herein have their conventional meaning as commonly understood by those having skill in the relevant art(s).” Ex. 1001, 4:64–67. Thus, the Specification itself cautions against construing the claim terms such as “secure identifier” as limited to the scope of the disclosed embodiments. Here, Patent Owner has not cited any express definition of “secure identifier,” or identified any explicit disclaimer of claim scope that might justify narrowing the scope of this claim term to specific embodiments disclosed in the Specification. In the absence of such a definition or disclaimer, we are not persuaded that the scope of the claim term “secure identifier” should be limited to specific aspects of the preferred embodiments cited by Patent Owner. See Prelim. Resp. 7–14. On this record, and at this stage of the proceeding, we decline to adopt Patent Owner’s proposed construction and preliminarily construe “secure identifier” as “a credential that can be used to securely verify the identity of a device, such as an airborne object or ground-based transmitter.”8” slip op. at 10
- Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateNot entitled to earlier dateDecided for petitioner
“’071 Application lack adequate written description support for the “secure identifier” claim limitation. For a patent claim to be entitled to the priority date of an earlier-filed application, the earlier application must provide complete written description support for the claim as required by 35 U.S.C. § 112(a). L.A. Biomedical Rsch. Inst. at Harbor-UCLA Med. Ctr. v. Eli Lilly & Co., 849 F.3d 1049, 1057 (Fed. Cir. 2017) (“L.A. Biomed”). To satisfy this requirement, the written description must “reasonably convey” to a person of ordinary skill in the art that the inventor had possession on the claimed priority date of each limitation of the later-claimed subject matter. L.A. Biomed, 849 F.3d at 1057. It is not enough that an earlier application’s disclosure “renders the later-claimed invention obvious;” as “the disclosure must describe the claimed invention with all its limitations.” L.A. Biomed, 849 F.3d at 1057. On this record, we agree with Petitioner that the ’153 Provisional and ’071 Application lack adequate written description support for the “secure identifier” limitation of claim 21. We have preliminarily construed “secure identifier” as “a credential that can be used to securely verify the identity of a device, such as an airborne object or ground-based transmitter.” See supra § II.B. As discussed above, the Specification of the ’959 Patent does not use the term “secure identifier,” but the Specification contains extensive discussion of the need for an identification credential that is secure (e.g., difficult for a bad actor to clone or impersonate). See, e.g., Ex. 1001, 1:56– 65 (discussing the need for a system that is difficult to “clone”), 10:20–49 (discussing the need “trust” between a drone and ground-based equipment, and the need for a way to verifying the drone’s credentials), 11:5–12:62 (disclosing the use of encryption and a rotating SSID to generate a secure identifier for a drone). None of the portions of the Specification cited above is present in the ’153 Provisional or the ’071 Application. See generally Ex. 1006, 1007. The ’153 Provisional and ’071 Application discuss the need for identifiers for low-altitude aircraft (see, e.g., Ex. 1006, 2; Ex. 1007, 9), but there is no discussion of any need for an identification credential to be secure or resistant to cloning or impersonation. See generally Ex. 1006, 1007. The ’153 Provisional and ’071 Application do not disclose the use of encryption, SSIDs (much less rotating SSIDs), or any other technologies for the purpose of verifying the authenticity of an identification credential. See generally id. Based on our review of the ’153 Provisional and ’071 Application, we preliminarily conclude that neither of these applications would have reasonably conveyed to a person of ordinary skill in the art that the inventor then had possession of the concept of the “secure identifier” that was later claimed in the ’959 Patent.” slip op. at 12

“arguments and evidence for purposes of institution that would support determining that a person of ordinary skill in the would have been motivated to combine the teachings of Shin and Aoyama. As one example, Amazon contends that the proposed combination is merely the addition of one known element (i.e., “Aoyama’s natural language processing and information retrieval”) to another known element (i.e., “Shin’s voice processing and response device”) to obtain predictable results (i.e., “identifying a user’s intent and providing information responsive to such intent”). Pet. 19–20 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 83). As another example, Amazon contends the proposed combination also represents the addition of one known element (i.e., “Aoyama’s word replacement” feature) to another known element (i.e., “Shin’s distance-based content abbreviation/simplification”) to obtain predictable results (i.e., “using word replacement to simply content for distant users”). Id. at 25–26 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 100). Amazon also presents sufficient arguments and evidence for purposes of institution that would support determining there is a reasonable expectation of success in making the proposed combination. Id. at 20 (citing Ex. 1002 ¶ 84), 27–28 (citing Ex. 1002 ¶ 102; Ex. 1011 ¶¶ 97, 98 Fig. 7). To the extent SoundClear argues that Amazon is required to identify a problem a person of ordinary skill in the art would have sought to solve when combining the teachings of Shin and Aoyama, we do not agree. See Prelim. Resp. 31–32. This line of argument runs contrary to the principles of law articulated in KSR. In KSR, the Supreme Court emphasized “an expansive and flexible approach” to an obviousness evaluation. KSR, 550 U.S. at 415; see also Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347, 1363 (Fed. Cir. 2018) (“KSR did not impose a rigid requirement to identify . . . a problem to be solved in the art . . . .”). The Supreme Court stated that, “[o]ften, it will be necessary for a court to look to interrelated teachings of multiple patents,” amongst other things, “to determine whether there was apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418.

“Based on the preliminary record, we discern no deficiency in Amazon’s characterizations of Shin, Aoyama, or the general background knowledge in the art. In addition, for purposes of institution, we are persuaded by Dr. Stern’s testimony concerning the relevant disclosures in Shin and Aoyama. At this stage of the proceeding, SoundClear argues that Shin does not teach limitations 1[b]—“a voice classifying unit configured 1[b][i] to calculate a distance between the user and the output-content control device by a proximity sensor 1[b][ii] to classify the voice into either a first voice or a second voice based on the calculated distance.” See Prelim. Resp. 19–22. a. Limitations 1[b]—“a voice classifying unit configured to 1[b][i] calculate a distance between the user and the output-content control device by a proximity sensor to 1[b][ii] classify the voice into either a first voice or a second voice based on the calculated distance” In the Preliminary Response, SoundClear contends that Shin fails to teach voice classification because “Shin is incapable of distinguishing [between] multiple voices.” Prelim. Resp. 21. More specifically, SoundClear argues that Shin cannot teach classifying a voice into a first voice or second voice because “Shin never refers to a ‘first user’ or ‘second user’ or ‘multiple users.’” Id. (citing Ex. 1003 generally); see also id. at 26– 27 (arguing that Amazon misstates the record because Shin never discloses a “first voice” nor a “second voice”). Instead, SoundClear asserts that Shin only contemplates a single user (i.e., user 10) when calculating the distance between the user and an electronic device (e.g., Shin’s electronic device 100). Id. at 21–22 (citing Ex. 1003 ¶¶ 37, 38). Based on the preliminary record, Amazon presents sufficient evidence that would support a finding that Shin teaches “a voice classifying unit configured to calculate a distance between the user and the output-content control device by a proximity sensor to classify the voice into either a first voice or a second voice based on the calculated distance.” Pet. 10–14. Shin discloses that “processor 120 may determine an output scheme of corresponding content based on a distance between a user and the electronic device 101.” Ex. 1003 ¶ 53. Shin’s processor 120 accomplishes this distance calculation by using distance detection module 180, which may include various sensors, such as a proximity sensor. Id. ¶ 66; see also id. ¶ 153 (disclosing an embodiment where electronic device 901 includes sensor module 940, which, in turn, includes proximity sensor 940G). Shin’s Table 3 illustrates how the distance between the user and electronic device 101 determines the output scheme. Id. ¶ 86, Table 3. For instance, Shin’s Table 3 illustrates classifying the user’s voice input as a “first voice” when the distance between the user and electronic device 101 is between 1 to 2 meters, and classifying the user’s voice input as a “second voice” when the distance between the user and electronic device 101 is less than 1 meter.

Pet. 52 (citing Ex. 1002 ¶¶ 212–215). Google argues that Mattavelli teaches merely optimizing transmission bandwidth is not sufficient and is potentially harmful, which provides an express motivation to combine Carmel’s and Mattavelli’s complementary teachings to ensure that different, related links in the streaming playback chain are optimized together. Pet. 53 (citing Ex. 1002 ¶¶ 216–217; Ex. 1004, 2310).

Nevertheless, as discussed above, Petitioner has provided contrary evidence, including statements from Patent Owner’s patent application, suggesting that, “due to the various differences and diversity of biomolecules depending on the genus and species of the horseshoe crab,” it had not been possible “to accurately determine the full-length sequence structure, expression, and function of [Limulus] proteins and genes using conventional methods” more than 20 years after complete gene and amino sequences from two Tachypleus horseshoe crab species had been reported. Pet. 35 (citing, e.g., Ex. 1005 ¶¶ 12–17). Thus, even if we were to take the Frohman Declaration into account, we find that Petitioner has established a reasonable likelihood 28 of success that the ’767 application disclosures did not enable an ordinarily skilled artisan to make and use the invention of the challenged claim without undue experimentation. Furthermore, assuming that the disclosures in ’767 application would have enabled an ordinarily skilled artisan to express recombinant Limulus polyphemus Factor C protein in HEK293, we find Petitioner has established, sufficient for purposes of institution, that the disclosures do not enable an ordinarily skilled artisan to make such a protein exhibiting the “full scope” of the claimed residual activity, without undue experimentation. Patent Owner cites to disclosures in the ’767 application that (1) describe how to produce recombinant Factor C in HEK293 cells and measure residual activity, (2) suggest “Factor C expressed in mammalian cells can have low susceptibility to activity inhibition by ions,” and (3) provide examples where residual activity met the required minimum. Prelim. Resp. 26–27, 32–34. Nevertheless, whether an ordinarily skilled artisan would have been able to make, based on these disclosures and without undue experimentation, a recombinant Factor C protein having residual activity encompassed by claim 21 but higher — even significantly higher — than that achieved in the example, is a fact intensive issue that would benefit from further development during trial.15 See, e.g., In re” slip op. at 28

“350 receiving a request for a listing of “services” from a gateway device and provisioning one or more tunnel servers has not been shown to teach generating “a list of available servers.” There is no persuasive evidence to support Petitioner’s assertion. Petitioner relies on unsupported argument because, at best, Hankins discloses gateway devices 311 and 321, each of which is located in different logical broadcast domains, requesting services from one another. Ex. 1005, 12:9–16. This particular disclosure, however, does not appear to implicate the functionality of Hankins’s controller 350, much less result in controller 350 generating a list of available tunnel servers that would allow gateway devices 311 and 312 to exchange a listing of “services” therebetween. Petitioner’s reliance on Hankins’s controller 350 provisioning additional tunnel servers both to improve performance and without human intervention fares no better. Ex. 1005, 25:45–55. There is no indication in Hankins that this provisioning performed by controller 350 is done in response to receiving a request for a list of available tunnel servers from either gateway device 311 or 312.” slip op. at 20

“Based on the plain language alone, there are “end-to-end tunnels” which “connect[] the first device and the second device” of the network system. In addition, “the person of ordinary skill in the art is deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. As already noted, the parties appear to agree that the specification does not define explicitly an “end-to-end tunnel.” In describing Figure 33 of the ’505 patent, reproduced above in Section I.D.2, the specification describes Figure 33 as illustrating “GVN Tunnel from LAN to EDP to SRV_AP to EPD to LAN. This variation illustrates an end-to-end GVN tunnel(s) between edges of two LANs via one SRV_AP.” Ex. 1001, 33:8–11 (emphasis added). The specification further describes Figure 33 as showing one tunnel between EPD-1 and AP-1. This is joined to a second tunnel between AP-1 and EPD-2. There are three neutral hops within the Third Layer of the GVN represented by NH1, NH2, and NH3 as compared to the 13 hops on the base Internet between EH3 and EH15. Id. at 33:15–19. This disclosure shows the end-to-end GVN tunnel has two hops, one between EPD-1 and AP-1, and one from AP-1 to EPD-2. The intermediate connection at AP-1 teaches the tunnel may be interrupted, contrary to Patent Owner’s assertion that Figure 33 of the ’505 patent supports a construction requiring the tunnel to be “uninterrupted.” See PO Resp. 9–10; see also Section II.D.2 below (addressing Patent Owner’s “uninterrupted” argument).” slip op. at 19

“Patent Owner’s assertion that an “intermediate tunnel” is not an “endto-end tunnel. See, e.g., PO Sur-reply 20–21 (arguing Petitioner’s annotated version of Figure 2 of Hankins teaches only “intermediate tunnels”). Given our claim construction supra, we find Hankins’s tunnels are “end-to-end tunnels” even if they are made of separate segments. Based on our final construction, and for the reasons discussed in Section II above, on this complete record we find that Petitioner has shown that Hankins teaches or suggests limitation 1.3. For completeness, we have reviewed Petitioner’s arguments and evidence explaining how Hankins alone or in combination with Munger teaches the remaining limitations of claim 1, and we agree with and adopt Petitioner’s analysis. See Pet. 30–32, 38–44. Accordingly, Petitioner has demonstrated by a preponderance of the evidence that the subject matter of claim 1 would have been obvious over Hankins alone or in combination with Munger.” slip op. at 30

“inside” it, the evidence does not support Patent Owner’s position. First, the plain language of independent claim 1 states that the proxy object “compris[es]” the one or more haptic output devices. Ex. 1001, 10:42–43. This is broader than the “within” language of the non-entered amendment. See Ex. 1002, 258. Not only does the evidence fail to show clear disclaimer (see United States v. Telectronics, Inc., 857 F.2d 778, 782–83 (Fed. Cir. 1988)), the adoption of broader “comprising” language shows an intent for the claims not to be limited to systems in which the proxy object contains haptic output devices “inside” it. We also do not agree with Patent Owner that the applicant’s attempts during prosecution to distinguish Gonzales are a clear disclaimer of claim scope. The applicant argued that Gonzales’s AR glove, which contained haptic output actuators in it (see, e.g., Ex. 1008 ¶¶ 80–82, Fig. 3B), was not a “proxy object” as recited in the claims because “the virtual objects and/or visible alterations to the vehicle [the user is sitting in while wearing the 6 Once again, Patent Owner mistakenly references Exhibit 2001. glove] are not overlaid on the AR glove . . . [a]nd the physical portions of the vehicle were visible alterations are overlaid do not include any feedback devices.” Ex. 1002, 287. Thus, the issue raised during prosecution was not whether the AR glove comprised haptic output devices—which it clearly did even under Patent Owner’s proposed construction—but whether the AR glove had modified visual effects displayed on it as per limitation 1D3. slip op. at 11

“For the above reasons, we decline to adopt Patent Owner’s proposed construction of “a proxy object comprising one or more haptic output devices” as meaning “a physical object that acts as a proxy for a virtual object and that itself contains inside a haptic output device, e.g., an actuator.” PO Resp. 10.

“Alternatively, we find persuasive Petitioner’s argument that a person of ordinary skill in the art would have had used both the camera data and the inertial sensor data in determining the “reloading” haptic effect. Pet. 77; Pet. Reply 19–22; Ex. 1003 ¶ 318; Tr. 31:3–10. This is evident in light of Rogers’s disclosures (1) that both sets of data are used to determine the pointing direction of interface object 104 in at least some contexts (Ex. 1010 ¶ 106); and (2) that the “reloading” haptic effect is based on the pointing direction (Ex. 1010 ¶ 105).
