      “E. Level of Ordinary Skill in the Art Based on the argument and evidence presented in the Petition and Patent Owner’s preliminary response, we determined, as stated in our Decision on Institution, that “a person of ordinary skill in the art would have had a Bachelor’s degree in electrical engineering and two or more years of experience working with audio and wireless communications systems.” 230 Dec. on Inst. 16; 232 Dec. on Inst. 22−23. Patent Owner reiterates its position that a person of ordinary skill the art would have had “a bachelor’s degree in electrical engineering or a related subject and two to five years’ experience working with multi-track audio and wireless communications systems in the professional performance industry.” 230 IPR, PO Resp. 6−7 (emphasis added) (identical passage in 232 PO Resp. 8). Thus, the dispute centers on whether the level or ordinary skill includes specific work experience with multi-track audio in the professional performance industry. We do not agree that this specific work experience is necessary to the level of ordinary skill in the instant proceedings. In determining whether an invention would have been obvious at the time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham v. John Deere, 383 U.S. 1, 17−18 (1966). “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 of 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). In determining the level or ordinary skill, we may consider various factors including “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, 57 F.3d 1573, 1579, (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). Patent Owner’s proposed specificity of work with multi-track audio in a professional performance industry is not supported by the record. First, Patent Owner submits conclusory declaration testimony of James DeFilippis—repeating verbatim, and without any supported reasoning, Patent Owner’s proposed level of ordinary skill. Ex. 2140 ¶ 15. As such, the testimony is not persuasive. Second, Patent Owner’s additional declaration testimony of Jack” slip op. at 12

      “data” means “mono or stereo audio files created from independent, isolated locally generated audio files, such files suitable for creation of a multi-track audio file.” 230 PO Resp. 9−10 (citing Ex. 2140 ¶¶ 131, 134). This argument is unsupported by the claim language or specification. The claim does not require the creation of audio files, much less a “multi-track audio file.” The specification describes storing audio files in memory without the specificity that Patent Owner urges we adopt. See 230 IPR, Ex. 1001, 13:1−14. Accordingly, we are not persuaded by Patent Owner’s proposed construction of “local audio data.” Rather, we understand “audio data” to have a plain and ordinary meaning, such as the one given to the term by the District Court in the underlying litigation. 230 IPR, Ex. 1037, 10. We adopt the District Court’s construction of “audio data” to mean “data comprising audio signals in digital form.” Id. This finds support in the specification as the audio is described as being converted into digital audio and stored in a file. See 230 IPR, Ex. 1001, 13:1−14. Our conclusion is consistent with the plain and ordinary meaning of the term as that would be understood by a person of ordinary skill in the art, and we see no reason to deviate from the conclusions of the District Court on this point.” slip op. at 21

Patent Owner asserts that Petitioner has failed to establish that these documents reflect the understanding of a person of ordinary skill in the art, or that they are consumer-oriented documents, but not technical references or sources for understanding the meaning of claim terms. 230 IPR, Paper 64, 3−4. According to Patent Owner, these exhibits lack a “technical foundation” that establishes the technical meaning of a claim term. Id. We do not agree with Patent Owner as it conflates relevance with sufficiency of evidence to prove a contention on claim construction. Dictionary definitions are often useful when determining a claim term’s plain and ordinary meaning in the context of the specification, and as such are relevant when claim terms are disputed. Phillips, 415 F.3d at 1312. Furthermore, the evidence of record shows testimony as to whether the “Sweetwater” glossary entry for “body pack” would be relevant to the meaning of the term in the “world of wireless performance.” 230 IPR, Paper 67, 4 (citing Ex. 1073 ¶ 42).

Patent Owner’s construction also is supported by Petitioner’s expert, Mr. Crosby, who agrees that “adjacent to one another as measured along a central axis,” could be “one meaning,” along with “many other meanings.” Ex. 2014,8 19:13–20:11.

In particular, we find unavailing Petitioner’s argument that Wampler teaches that magnetic pieces 88 (“a first magnetic device”) “are inserted [‘axially adjacent’] in…the impeller.” Id. at 20–21 (citing Ex. 1008 ¶ 80, Fig. 13; Ex. 1003 ¶ 174). We also find unavailing Petitioner’s reliance on Wampler’s Figure 13 and Mr. Crosby’s cited testimony that “the ‘impeller’ and ‘magnetic pieces’ are axially adjacent—situated next to each other on the same axis.” Id. at 21–22 (annotating Ex. 1008, Fig. 13; citing Ex. 1003 ¶¶ 174–176). Petitioner does not sufficiently explain this argument, but appears to conflate being adjacent along a central axis with about an axis. Id. We also find unavailing Petitioner’s argument that under Patent Owner’s construction, Wampler also teaches this limitation, because Patent Owner “concedes that ‘axially adjacent’ components ‘have positioning that is next to one another, perhaps touching or sharing a common side, when measured along the axis.’” Pet. Reply 14–15 (citing PO Resp. 14).

      “Petitioner contends that one of ordinary skill in the art “would have had (1) at least a bachelor’s degree in Mechanical Engineering, Computer Engineering, Chemical Engineering, Materials Science, or a related field, and (2) at least two years of research or industry experience in 3D printing or materials used for 3D printing.” Pet. 5 (citing Ex. 1003 ¶¶ 14–16). Petitioner also argues that “[a]dditional experience could substitute for a formal degree or formal training (and vice versa).” Id. Patent Owner proposes a slightly different level of skill, arguing that a person of ordinary skill in the art “would have had a bachelor’s degree in Mechanical Engineering, Computer Engineering, Chemical Engineering, Materials Science, or a comparable field and at least two years of experience related to 3D printing, with additional experience potentially being a substitute for a formal degree or training (and vice versa).” Prelim. Resp. 24. Neither party explains why the outcome of this case would be affected by the adoption of any of the proffered definitions of a person of ordinary skill in the art.

      “According to the ’713 patent, “[p]urge tower 24 itself may be . . . recycled or otherwise discarded as desired.” Ex. 1001, 8:27–28. This description provides some support for Patent Owner’s view, because a purge tower too intimately integrated with the part would be difficult or impossible to recycle or discard. This is further supported by the ’713 patent’s statement that “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Id. at 8:30–34. It also is supported by Dr. Hickner’s testimony that the ’713 patent “clearly shows . . . the 24 purge tower separated from the part” and that “the purge tower is a separate physical object.” Ex. 2016, 28:8–10, 64:1–9. On the other hand, there is evidence supporting Petitioner’s view that, as long as the purge tower is generally separate from the part and the support structure, it may still make contact with those portions of the print. As noted above, “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Ex. 1001, 8:30–34. This language does not exclude locations adjacent to or in contact with the part or the support structure. Thus, determine that a “purge tower,” as that term is used in the context of the ’713 patent, may not be an integrated portion of a printed part or support structure but need not be free of all contact with the printed part or support structure.” slip op. at 9

    • BurdenNot shown unpatentable

      “There is evidence of record to support both Petitioner’s view and Patent Owner’s view. On the record developed at trial, however, we cannot say that the preponderance of the evidence favors Petitioner, who bears the burden of proof. See 35 U.S.C. § 316(e). Accordingly, Petitioner has not shown by a preponderance of the evidence that KISSlicer teaches printing a layer of a purge tower each time the printer switches one extruder to the operating mode. Because proving the obviousness of claims 1 and 16 requires such a showing, Petitioner has not shown by a preponderance of the evidence that claims 1 and 16 would have been obvious over the combination of Priedeman and KISSlicer. 5. Analysis of Remaining Claims Claims 2, 6, 7, 9, and 17 all depend, directly or indirectly, from claim 1 or claim 16. Accordingly, they all include the limitations of either claim 1 or claim 16. Because, as discussed above, Petitioner has not shown that the combination of Priedeman and KISSlicer teaches or suggests all the limitations of claims 1 and 16, Petitioner also has not proven by a preponderance of the evidence that claims 2, 6, 7, 9, and 17 would have been obvious over that combination of references.” slip op. at 21

      “On the record developed at trial, we agree with Petitioner.

Thus, not only was it possible for people of ordinary skill in the art to locate KISSlicer; people of ordinary skill in the art actually did locate it. Accordingly, Petitioner has shown by a preponderance of the evidence that KISSlicer was publicly accessible.” slip op. at 19

      “summarized above, we determine that a person of ordinary skill in the art would not have implemented Toge’s physician-side computer as a web server using a “localhost” architecture as proposed by Petitioner because such a configuration cannot communicate with external devices over the public internet, a deficiency that directly contradicts Petitioner’s stated motivations for the combination of permitting broad data access. Petitioner’s expert, Dr. Chatterjee, expressly acknowledged in his Reply Declaration that when a client and server reside on the same machine, the communications between them do not traverse the internet. Ex. 1069 ¶ 8. Specifically, Dr. Chatterjee cited the Microsoft Computer Dictionary’s definition of “localhost” as “[t]he name that is used to represent the same computer on which a TCP/IP message originates,” noting that “[a]n IP packet sent to localhost has the IP address 127.0.0.1 and does not actually go out to the Internet.” Id. (citing Ex. 1070, 316). Accordingly, Petitioner’s proposed configuration of placing both the client and web server on Toge’s physician-side computer would create a closed loop of communication that does not reach the broader network. Id. As noted by Patent Owner, “[i]f ‘the physician-side computer and the web server are on one machine,’ the local web server would not communicate with other devices via the Internet.” Sur-Reply, 3–4 (comparing Ex. 1069 ¶ 19 with id. at ¶ 8). Thus, the consequence of Petitioner’s proposed Toge-Kumar configuration is that other devices in the system, such as the PAP device that generates the treatment data and any remote client devices that might need to access that data, would be unable to send data to or retrieve data from the localhost web server. Patent Owner persuasively argues, supported by evidence of record, that under Petitioner’s proposed configuration, “the PAP device could not send data thereto nor could other clients receive data therefrom, as only the local client browser can exchange data.” Id. (citing Ex. 1069 ¶ 8); see Ex. 2003, 4 (one-tier architecture “is not suitable for a web application” because “it can only access data available in a single computer or server” and therefore “is not suitable for a web application.”); Ex. 2022, 3 (Unlike more advanced multi-tier systems, a one-tier architecture “cannot transmit information from one client machine to another.”); Ex. 2020, 4 (While “the client process and server process can be on the same computer,” this architecture “is rarely used today” precisely because it cannot “take advantage of the distributed computing environment.”).” slip op. at 29

      “its burden of explaining why a person of ordinary skill in the art would have implemented a remote internet site in Toge’s system in the specific fashion Petitioner asserts (i.e., using the physician-side computer as a web server). As Patent Owner aptly states, the operative question is not merely whether a person of ordinary skill in the art would have modified Toge’s system to include a remote internet site, but whether the artisan would have modified Toge’s system to include a remote internet site “on a physician’s client computer” in accordance with the specific implementation argued by Petitioner. Sur-reply 2. On this critical question, Petitioner’s arguments are thin. Petitioner’s declarant Dr. Kirkness states that a person of ordinary skill in the art “would have understood that one common way to access data transmitted over the internet, like the data from Toge’s wireless PAP device, is via a remote internet site.” Ex. 1003 ¶ 214. This assertion is reasonable. Indeed, prior art of record, such as Kumar, illustrates use of a central server that hosts a browser-based engine that can be accessed through web pages. See, e.g., Ex. 1008 (Kumar) Fig. 1A, ¶¶ 67, 72, 79, Pet. 10.

In view of the low level of detail required to satisfy the written description requirement, Petitioner has not persuaded us that the Specification’s example of a quick-connect system configured to secure the massaging head as the piston reciprocates fails to provide sufficient written description support for the “quick-connect system” recited in independent claims 1 and 18.” slip op. at 14

      “Contrary to Petitioner’s assertion, the Specification provides guidance as to what amount of deviation from a perfect cylinder is still “substantially cylindrical.” The Specification describes: Quick-connect system 600 includes a piston 602 that has a hollow-end bore 608 for receiving the shaft 621 of a massaging head 620. Located within the bore 608 of piston 602 is a cylindrical seat 604. Cylindrical seat 604 retains a magnet 606. Magnet 606 is illustrated with its north pole located flush with the seat and facing toward the opening in bore 608. Massaging head 620 includes a shaft 621 having a cylindrical pocket 622 at the distal end. Located within the cylindrical pocket 622 is a magnet 624. Magnet 624 is positioned so that its south pole is located at the distal end of shaft 621. Accordingly, when the shaft 621 of massaging head 620 is slid into opening in bore 608, the magnets 606 and 624 are attracted to one another and magnetically hold massaging head 620 firmly in place. Ex. 1001, 6:57–7:3. In view of the description of quick-connect system 600, the Specification sets forth a standard for ascertaining whether the bore and the seat located within the bore are “substantially cylindrical.” To wit, the bore and the seat within the bore are “substantially cylindrical” when the massaging head and magnet are respectively received therein so that the magnet in the seat and the magnet in the pocket of the massaging head can magnetically hold the massaging head firmly in place. Furthermore, Dr. Pratt testifies that “[m]agnetic connectors comprise a magnet on at least one of the two objects to be joined. These types of connectors are ubiquitous even today for driving threaded fasteners.” Ex. 1002 ¶ 56. Dr. Pratt also testifies that a POSITA would understand how to take into account certain variances, like runout. Ex. 2033, 25:3–17. Dr. Pratt’s testimony shows that magnetic connectors are well known and that a POSITA would be able to determine whether the bore and the seat within the bore were “substantially cylindrical” for a secure connection of the massaging head. In view of the foregoing, Petitioner has not persuaded us that the claim term “substantially cylindrical” recited in claims 13–16 fails to inform, with reasonable certainty, the shapes of the bore and the structure within the bore. Petitioner has not proven, by a preponderance of the evidence, that any of claims 13–16 are unpatentable under 35 U.S.C. § 112(b) as indefinite.” slip op. at 19

Claim Interpretation We interpret the claims of the challenged patent using the same claim construction standard that would be used to construe the [claims] in a civil action under 35 U.S.C. 282(b), including construing the [claims] in accordance with the ordinary and customary meaning of such [claims] as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner argues that “the claim terms should be given their plain and ordinary meaning and no claim construction is necessary.” Pet. 15. We did not interpret any terms in the Decision on Institution. Dec. on Inst. 9–10. Patent Owner does not propose interpretations of any claim terms in its Response.

An indication that a new issue is improperly raised in a reply is where a petitioner submits “new evidence necessary to make out a prima facie case” of unpatentability, such as a “newly raised rationale to combine the prior art references that was not expressed in the petition.” Id. That is the case here. Petitioner’s rationale in the Petition for why a person of ordinary skill in the art would have been motivated to lower Bowen’s 0.9 eV barrier height to 0.33 eV based on Soukup was that such an artisan would have expected lowering the barrier height to increase TMR. See Pet. 34–36. Faced with Dr. Bokor’s testimony on cross-examination, Petitioner presents a new theory in its Reply that a person of ordinary skill in the art would not have known what impact lowering the barrier height would have (increase TMR, decrease it, or have no impact at all), but would have expected it to change in some “uncertain” way, which is a “legally sufficient motivation” in Petitioner’s view. See Reply 6–10, 13–16, 23–25. In other words, “[r]ather than explaining how its original” position that lowering barrier height would increase TMR “was correct,” Petitioner articulated “an entirely new theory . . . absent from the [P]etition” after Patent Owner cross-examined Dr. Bokor and “pointed out the flaws of [Petitioner’s] position” in its Response. See Wasica Finance GmbH v. Continental Auto. Sys., Inc., 853 F.3d 1272, 1286 (Fed.

      “Ultimately, the cross-examination testimony above is inconsistent with Dr. Bokor’s opinions in his declaration that, for example, “[i]t was understood to one of skill that lowering the barrier height to increase tunneling would have increased the TMR,” and “[o]ne of skill would have been motivated to adjust oxygen vacancy defects to improve TMR by lowering the barrier height.” See Ex. 1024 ¶¶ 176, 277 (emphasis added); see also id. ¶ 172 (“[O]ne of skill in the art would have been motivated to use [Soukup’s 0.33 eV] or similar height in an MgO MTJ to improve tunneling and hence TMR in Bowen.”). Accordingly, we do not find Dr. Bokor’s declaration testimony regarding a motivation to lower Bowen’s barrier height credible. It is Petitioner’s burden to provide a reasoned, evidence-supported explanation for why a person of ordinary skill in the art would have been motivated to lower Bowen’s 0.9 eV barrier height to 0.33 eV as disclosed in Soukup. See NuVasive, 842 F.3d at 1383; Magnum Oil, 829 F.3d at 1380; TriVascular, 812 F.3d at 1066.

      “The invention, a reciprocating massage device, is in a predictable field, namely the electro-mechanical arts. Also, there is no evidence that the recited quick release connector is complex, even considering Patent Owner’s alleged understanding of it. Rather, Dr. Pratt testifies that a POSITA would be able to recognize a quick release connector for a particular application. According to Dr. Pratt, A person of ordinary skill in the art would consider a number of factors, depending on the context and specific application of the connector, to determine whether a connector provides a “quick release.” Such factors could include whether the connector is designed to manually and easily connect and disconnect two objects, and whether tools are necessary to do so. Other factors to be considered may be based on the specific application or operating environment. Ex. 1002 ¶ 58. Given the predictability of the electro-mechanical arts and lack of complexity of the recited quick release connector, a low level of detail is required to satisfy the written description requirement.

      “challenge, the crux of the parties’ dispute revolves around the limitation in claim 1 of “an axial region of the shaft body extending from the second end and being tapered relative to a longitudinal axis of the shaft.” We agree with for the tapered axial region and that starting point would be the extremity of the shaft not an undefined point in the “end region.” Because Patent Owner proposes a construction of “end” that would have general application to all claim terms including the first end of the shaft, the second end of the shaft, and the sleeve end, and that construction has no bearing on the issues we address below, we do not reach Patent Owner’s proposed general construction of “end” by itself. We determine that no other claim terms require express construction for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “This paragraph discusses “accurate alignment” in connection with joint 21, not tapered end 25. Ex. 1018, 3:23–35. The paragraph subsequently states that both joint 21 and end 25 are tapered but that shaft end 25 may alternatively be cylindrical. Id. We also find nothing in this paragraph supporting Petitioner’s assertion that alignment “is notoriously more difficult with purely cylindrical shafting” (Pet. 16–17). In order to support its position, Petitioner improperly conflates separate statements in this paragraph of Piepho, i.e., joint 21 provides accurate alignment, joint 21 is tapered, and end 25 is tapered. Petitioner makes an unsupported logical leap that the result of these three statements is that tapered end 25 provides accurate alignment. However, Petitioner fails to reconcile this argument with the final sentence in this paragraph that shaft end 25 may also be cylindrical as shown in Figure 4. Figure 4 “is an external view of another embodiment of” Piepho’s shaft. Ex. 1018, 2:49–50. In Figure 4, joint 21 has the same tapered configuration as shown in Figure 3 but end 25 is not tapered. Based on our review of Piepho’s Figures 3 and 4, we find that Piepho’s reference to “accurate alignment” refers to joint 21 and not to tapered end 25 as Petitioner alleges. Because Mr. Smith’s testimony (Ex. 1002, 59) essentially parrots the Petition on this point and is inconsistent with our finding, his testimony is entitled to little, if any, weight. For the foregoing reasons, we find that Petitioner has not established that a person of ordinary skill in the art would have been motivated to would teach this claim limitation.8 Because Petitioner has not shown that the combination of Polinski and Piepho teaches limitation 1b or an adequate motivation to combine, Petitioner has not shown by a preponderance of the evidence that claim 1 is obvious over Polinski, Piepho, and Harless.” slip op. at 27
