    “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

    “5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. 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.

    “We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

    “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

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

    “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))).” slip op. at 7

    “At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (“[A] determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements.” (citing In re Etter, 756 F.2d 852, 859 (Fed.

Graham, 383 U.S. at 17. “The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu-Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). The “person having ordinary skill in the art” is a hypothetical construct, from whose vantage point obviousness is assessed. In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Factors pertinent to a determination of the level of ordinary skill in the art include “(1) the educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of active workers in the field.” Env’t Designs, Ltd. v.

Relying on the testimony of Dr. Stern, Amazon argues the following: [a] person of ordinary skill in the art . . . would have had a minimum of a bachelor’s degree in computer engineering, computer science, electrical engineering, or a similar field, and approximately two years of industry or academic experience in a field related to controlling the audio output of electronic devices. Work experience could substitute for formal education and additional formal education could substitute for work experience. Pet. 7 (citing Ex. 1002 ¶¶ 28–32). In the Preliminary Response, SoundClear does not address Amazon’s assessment of the level of skill in the art. See Prelim. Resp. At this stage of the proceeding, we adopt Amazon’s uncontested assessment of the level of skill in the art because (1) it is consistent with the ’675 patent and the asserted prior art; and (2) it is supported by the testimony of Dr. Stern.” 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. Moreover, the Supreme Court explained that, “[u]nder the correct analysis, any need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Id. at 420.” slip op. at 26

    “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.

    “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

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.
