Petitioner does not explain how filling in a gap between the isolator 100 and a substrate necessarily results in “each of the plurality of optical isolators [being] disposed substantially in parallel relative to each other,” as recited in claim 1. The cited portion in paragraph 43 references Figures 5 and 6, which depict Embodiment 1 of Wang and are reproduced below. Figures 5 and 6 of Wang depict isolators 100, base 311, and baffles 312. Although paragraph 44 of Wang states that “[t]he substrate includes a base 311, and baffles 312 and isolators 100 sequentially disposed on the base 311,” Petitioner does not sufficiently persuade us how Wang’s disclosure “sequentially disposed” isolators necessarily discloses that the isolators are “disposed substantially in parallel relative to each other” as recited in independent claim 1.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “image capture device” refers to an imaging-based barcode reader and not a laser-based barcode scanner because we are persuaded that claim language and Specification support that interpretation and also because Patent Owner persuasively shows that a person of ordinary skill in the art would have understood the term as such. Claim 1 recites an “image capture device configured to capture an image.” Ex. 1001, 16:24–25. The plain meaning of the claim term requires that the image be captured, not just scanned. The claim further requires “generating an output based on the information embedded in the image,” requiring that information is retrieved from the captured image. Id. at 16:32–33. A device that does not capture an image is not an “image capture device” under the plain language of the claim. A laser-based barcode scanner employs light reflected from a laser beam to “generate an electrical signal that corresponds to the bars and spaces in the barcode being scanned.” See Ex. 2029 ¶¶ 42–43 (explaining in detail how laser-based barcode self-emitting a laser light across a code to be scanned, with a sensor tuned to capture the reflected light from the laser.”). It simply does not capture an image. slip op. at 14

    “Based on our review of the complete record, we determine that Petitioner’s stated level of ordinary skill in the art is reasonable because it is consistent with the evidence of record, including the asserted prior art. The field of the ’167 patent “relates generally to secure transactions, and more specifically, to methods and devices for providing secure identification, verification, and authorization using a portable secure device.” Ex. 1001, 1:8–11. The ’167 patent seeks “to provide methods and devices that are capable of providing secure transactions in a more efficient manner.” Id. at 3:11–13. Accordingly, we adopt Petitioner’s definition.

    “We agree with Patent Owner that Wang fails to disclose limitation 1[a]. Wang discloses a portable electronic authorization device (PEAD) that can be used as a self-checkout terminal. Ex. 1004 ¶ 115. In this context, Wang discloses By entering the UPC code or barcode using keypad on the PEAD or scanning in the UPC code or barcode using the input device built into the PEAD such as a barcode scanner or OCR reader, the PEAD can generate the receipt with the list of item prices through the wireless network and Internet by querying the item price using the barcode as the index for price lookup table which is Stored in a Server System. Id. (emphasis added). As discussed above (Section III.C.1), we are persuaded by Patent Owner’s arguments that the claimed “image capture device” refers to an imaging-based device and not a laser-based barcode scanner. Petitioner does not contend that Wang’s disclosure of the barcode scanner necessarily refers to an imaging-based device, but argues that Wang’s disclosure is sufficient because “both imaging-based barcode scanners and laser-based barcode scanners constitute image capture devices.” Reply 11.

Drummond Drummond is a patent titled “Automated Banking Machine System and Method,” and “relates to an automated banking machine apparatus and system that are capable of use in a wide area network, and which provides a user with a remote electronic receipt or other record related to a transaction performed at the machine.” Ex. 1008, code (54), ¶ 2. Drummond discloses that its automated banking machine, may “initiate the sending of a non-paper transaction receipt to the customer,” “[t]he receipt may be sent using a wide area network, such as the Internet,” and “[t]he receipt may be an electronic receipt, for example a receipt in the form of an e-mail message.” Id. ¶ 247. 2.

But this functionality does not refer to a web page from a server. Instead, this discussion is about a HTTP request that comes from a client device and may include one or more hidden JavaScript identifiers. See id. ¶¶ 50–55. The discussion about providing a response to a web browser on a client device refers to a response to the client device’s HTTP request, in the form of an error message, that is sent from the proxy server to client device. Id. ¶ 58. As Patent Owner points out, this is one of the two scenarios presented in Scoda, the other one being that HTTP request is sent to the server. Id.; PO Resp. 36; see also Ex. 2009 ¶ 70.

    “Dr. Scordilis. Based on the record, Petitioner fails to provide a sufficient reason to arrive at the claimed invention and satisfy the burden of showing obviousness. As Patent Owner essentially argues, Cabot (and all references relied upon by Petitioner and Dr. Scordilis) do not pertain to “quantizing a phase difference of the at least one overtone relative to the fundamental tone to embed at least one bit of the data to be embedded” as step 1C-2 requires. See PO Resp. 32–33. Petitioner also relies on Kudumakis to modify Srinivasan in asserting that step 1C-2 would have been obvious, but Petitioner’s reliance on Kudumakis is also faulty as explained below. See Pet. 22–27 (relying on Ex. 1006 (Cabot), Ex. 1007 (Kudumakis); Ex. 1028 (Risset), Ex. 1031 (Lipshitz), Ex. 1055 (“Cox-SSSW”); Ex. 1020 (“Cox- 1995” ); Ex. 1021 (“Wu”)). articulated reasoning with some rational underpinning” to show that one of ordinary skill in the art would have had a sufficient reason to modify Srinivasan’s frequencies to embed a quantized phase difference between a fundamental and its harmonic into the harmonic as step 1C-2 requires. See Kahn, 441 F.3d at 988 (“[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)); In re Fine, 837 F.2d 1071, 1075 (Fed. Cir. 1988) (“teachings of references can be combined only if there is some suggestion or incentive to do so”) (quoting ACS Hosp. Sys., Inc. v. Montefiore Hosp., 732 F.2d 1572, 1577 (Fed. Cir. 1984)). As noted above, Dr. Scordilis states that Cabot merely “opens the venue for exploration” for an artisan of ordinary skill to “try to . . . explore” watermarks. Ex. 2011, 75:16–22. Dr. Scordolis’s testimony relates to an “obvious to try” rationale, but neither Dr. Scordilis’s testimony, nor Petitioner’s showing, satisfies the conditions to support that rationale. In particular, Dr. Scordilis does not testify, and Petitioner does not show, that the technique of embedding phase difference codes into a harmonic relative to its fundamental was one of “a finite number of identified, predictable solutions” and a “known option[]” for hiding data. Cf. KSR, 550 U.S. at 402 (indicating that under an “obvious to try” rationale, “[w]hen there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill in the art has good reason to pursue the known options within his or her technical grasp” (emphasis added)).” slip op. at 25

    “The record supports Patent Owner’s characterization of Dr Scordilis’s testimony. Dr. Scordilis does not rely on any references that “have a frequencies specifically.” See Ex. 2011, 90:4–8 (testifying such references are “[n]ot in [his] report”). Moreover, Dr. Scordilis testifies that “[t]he value . . . of Cabot’s work is that he points to the fact that even in this very controlled experiment, although phase is detectable in an A/B type of setup under many, many repetitions, it really opens the venue for exploration that a [person of ordinary skill in the art] would try to capitalize and explore further to develop a watermark.” Id. at 75:16–22 (emphasis added). In summary, Dr. Scordilis testifies that no references (including Cabot) cited in his declaration discuss phase encoding of a harmonic phase relative to a fundamental phase for watermarking, and Cabot merely opens the door so that a person of ordinary skill in the art would “try to . . . explore further to develop a watermark” using harmonic phase coding data.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

I also agree that Patent Owner’s arguments attempt to recharacterize limitations [j] and [k] to raise issues that Patent Owner did not raise previously, in contravention of our Order that issues raised needed support from “where those issues were raised in previous briefings by the parties.” Paper 56, 2.

In Patent Owner’s Remand Brief, pages 1–7, the citations to argument previously raised do not support the arguments now presented by Patent Owner on remand.

    “7 Patent Owner’s Brief on Remand recognizes that there are two arguments Patent Owner raised in its Patent Owner Response that were not addressed in the Final Written Decision. See PO Remand Br. 1 (citing PO Resp. 24–37 (the construction of “locating encrypted information . . . within requested portions”), 38–58 (referring to Patent Owner’s “common keys” argument)). 8 The Final Decision also addressed Petitioner’s Motion to Exclude (Paper 42). See Final Dec. 28–37 (granting-in-part, denying-in-part, and dismissing-in-part Petitioner’s Motion). Our determinations on that Motion were part of Petitioner’s appeal to the Federal Circuit. See Paper 52. Because the Federal Circuit did not address this aspect of the Final Written Decision and the Federal Circuit’s decision does not impact our previous rulings on the Motion, we maintain those rulings here. Additionally, on remand, Petitioner requested authorization to file a motion for sanctions, which we held in abeyance until the parties’ briefing on remand was complete. See Ex. 3003, 1. Petitioner requests sanctions because of the impropriety of Patent Owner’s remand brief, including new claim construction arguments for limitations [1j] and [1k], and prejudice to Petitioner.

Although we reserved further consideration of Petitioner’s request, we expanded both the time and pages allowed for Petitioner’s responsive brief, and also allowed Petitioner to address any related issues in its responsive brief.

Additionally, with respect to the identification of the transistor and capacitor of the controlled current source as the control loop (Pet.

An identification of elements within the controlled current source as the only elements in the control loop is not consistent with the requirement that the controlled current source acts as a regulation element in control loop. Id. at 55; PO Sur-reply 15–16. Rather, an argument that the controlled current source and the current amplifier form a control loop (Pet. 21) appears more consistent with this limitation, however it is not clearly described or supported with evidence by Petitioner. Petitioner argues that the ’082 patent discloses that its control loop is formed when the first switching device S1 closes and the output of the adjusting circuit is connected to the input of the controlled current source and the capacitor 212 is charged to a specific current. Pet. Reply 10–11 (citing Ex. 1001, 7:45–53, 7:58–65, 8:1–21, Fig. 2a).

PO Resp. 49–50. This distinction is not persuasively addressed by Petitioner or its identification of only elements of Soneda’s transistor 11 and capacitor 13 as included in the control loop. See Pet. Reply 9–10 (discussing the “stage of operation” in which a capacitor is charged until a steady state is input of the controlled current source to an output of the current amplifier). For these reasons, we conclude that Petitioner has not met its burden to prove by a preponderance of the evidence that Soneda teaches the elements of claim 1.” slip op. at 22
