    “Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v.

Even if we were to consider this new argument, it would not be persuasive.

    “E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight.

    “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).

    “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.

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.

Although Patent Owner argues that “the supporting evidence [for its addition] is broadly present in the case, namely, in the Patent-in-Suit and the associated intrinsic evidence” (PO Sur-reply 3 n.6), Patent Owner does not direct us to any specific portion of the record. See United States v. Dunkel, 927 F.2d 955, 956 (7th Cir. 1991) (“Judges are not like pigs, hunting for truffles buried in briefs.”); DeSilva v. DiLeonardi, 181 F.3d 865, 866–67 (7th Cir. 1999) (“A brief must make all arguments accessible to the judges, rather than ask them to play archaeologist with the record.”). Additionally, while Patent Owner proposes expanding the definition, Patent Owner has not explained how that difference would materially affect the outcome of this proceeding. PO Resp. 2; PO Sur-reply 3 & nn. 4, 6. Dr. Akl uses Petitioner’s definition in his testimony (Ex. 1003 ¶¶ 22, 23) and Patent Owner makes no argument regarding how, if we adopted Patent Owner’s broader definition, Dr. Akl’s conclusions would be affected. Patent Owner’s use of its definition does not describe the conclusions of one “educated in general physics” differently to one of ordinary skill as defined by Petitioner. PO Sur-reply 6. Patent Owner does not present declarant testimony regarding knowledge of one of ordinary skill in the art under any definition.3 For these reasons, we maintain the definition of a person having ordinary skill in the art we adopted in the Decision on Institution: a person having ordinary skill in the art would have had experience in the hardware and software used in the field of securely transmitting and processing authorization requests over wired and wireless networks, such as requests for the processing of financial transactions, and a bachelor’s degree in computer science, computer engineering, electrical engineering, or a related study, and would have one or two years of experience with wired and wireless 3 See infra footnote 5. as financial transactions.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “Having analyzed the arguments and the evidence cited by Patent Owner, we do not agree. We begin with the claim language, which does not further describe the two transmission channels, let alone contradict the plain meaning. Ex. 1001, 6:5–19. Dependent claims also shed no additional light. Certain claims further specify transmission-channel-related requirements: that the first transmission channel be “selected from the group consisting of wireless and landline channels” (claim 7); that the request received via the first transmission channel be “provided via the Internet” (claim 5); or that the notifying step (via a second transmission channel) comprise “sending an SMS message to the customer (claim 2). Id. at 6:20–21, 6:28–29, 6:33–35. No claims further restrict claim 1 by describing both transmission channels. Id. Claim 9 requires that the notification be “substantially concurrent,” but nothing in the record establishes that substantially concurrent authorization and notification would require non-overlapping transmission channels, or that an overlap in the transmission channels, even if it did “encumber” the authorization process with the notification process, would prevent the processes from being “substantially concurrent.” While Patent Owner presents arguments about “the gist” of the invention (PO Resp. 4) and describes “an immediate separation of the two processes” as being disclosed by Figures 1 and 2 of the ’564 patent’s specification, we do not see in the specification an indication of a special disavowal of a broader scope. See Phillips, 415 F.3d at 1316–1317; PO Resp. 13 (“The specification of the ‘564 Patent does not express any intent to impart a novel meaning to the term distinct.”). Although we agree with Patent Owner that Figure 1 illustrates transmission channels that are separate and non-overlapping, we do not see any indication that this is more than a description of preferred embodiments or that there was a limitation of the invention to these embodiments, and our reviewing court “has repeatedly ‘cautioned against limiting the claimed invention to preferred embodiments or specific examples in the specification.’” Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1346–47 (Fed. Cir. 2015) (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1328 (Fed. Cir. 2002)). The specification similarly does not support that Figure 2 is intended as limiting.” slip op. at 16

    “Because we do not adopt Patent Owner’s construction (including considering its arguments regarding speed and security of transmissions in the ’564 patent), and instead adopt a construction encompassing overlapping between distinct transmission channels, see supra Section II.C.1, we determine that the requirement of limitation 1d that “the second transmission channel [must be] distinct from the first transmission channel” is disclosed by the different connections, different hardware elements, and independent operation of the two transmission channels identified in Horie, even though they overlap to some extent. Ex. 1006 ¶¶ 44, Fig. 1; Ex. 1003 ¶¶ 224–227; see PO Resp. 9. Lastly, Horie discloses that the authorization of a transaction occurs without requiring a response from the customer. Ex. 1006 ¶¶ 57, 58, 73; Ex. 1003 ¶¶ 232–233. For these reasons, we determine Petitioner has demonstrated by a preponderance of the evidence that the subject matter of claim 1 was anticipated by Horie.” slip op. at 29

    “Petitioner notes that a District Court has construed “access message” to mean “[a] signal or notification enabling or announcing access.” Pet. 4 (citing Ex. 1009, 3; Ex. 1010, 15, 20). However, Petitioner “maintains that the Board need not construe the term ‘access message.’” Reply 6. Patent Owner states that it “agree[s] on the construction of the term ‘access message’ to mean ‘a signal or notification enabling or announcing access.’” PO Resp. 7. However, Patent Owner argues that applying “access message” to Ludtke’s transaction confirmation “fails to account for the claim term ‘access to an application.’” Id. at 7–8. Rather, Patent Owner argues, a transaction confirmation “is a message announcing that a transaction has been completed.” Id. at 8. Patent Owner contends that “[t]he plain and ordinary meaning of ‘access message’ is a message enabling entry to, communication with, or use of an object wherein the object is the claimed application.” Id. (citing access, MERRIAM-WEBSTER DICTIONARY (available at https://www.merriam-webster.com/dictionary/access)). Here, Patent Owner appears to retreat on its agreement that “access message” can include a signal “announcing” access, and suggests that we limit “access message” to a signal “enabling” access. However, Patent Owner then returns to its agreement, stating that “[i]t would be improper to construe ‘access message’ as something other than a signal or notification enabling or announcing a user’s access to (ability to enter, communicate with, or make use of) an application.” Id.” slip op. at 16

    “As explained above, a person of ordinary skill in the art would have had at least a bachelor’s degree in Computer or Electrical Engineering or an equivalent engineering discipline, and at least three years of experience in the field of encryption and security, or the equivalent, while additional education could substitute for professional experience, and significant work experience could substitute for formal education. Mr. Carrothers claims to be “a financial services and retail leader with approximately thirty years of experience working in a variety of leadership roles in retail payments.” Ex. 2018 ¶ 1. He lists professional and consulting experience with retail payments, operational and risk management of a credit card portfolio, and payment insurance and acceptances in stores and online. Id. ¶¶ 1–5. His Curriculum Vitae (Ex. 2018, Appendix A) lists education including a Bachelor of Business Administration and a Master of Business has either the technical education or the technical experience to be a person of ordinary skill in the art. In response to Petitioner’s challenge to Mr. Carrothers’ qualifications, Patent Owner does not contend that Mr. Carrothers is at least a person of ordinary skill in the art.7 Rather, Patent Owner argues that “[t]o put the asserted portions of Ludtke in context, Mr. Carrothers provided testimony regarding the processing of credit and debit card payments with respect to online transactions based on his expertise and experience with retail payments.” Sur-reply 1. Patent Owner uses Mr. Carrothers’ testimony to support arguments regarding the timing and parties to the communications generated by Ludtke’s system, and to support arguments that the TPCH is a party to Ludtke’s transactions. PO Resp. 13–17 (citing Ex. 2018 ¶¶ 20–31). We find that Mr. Carrothers testifies on technical details regarding unpatentability, and that a declarant testifying as to such subject matter should have at least ordinary skill in the art.
