“We disagree with Patent Owner. Patent Owner argues that Petitioner’s reliance on Yadav (Ex. 1009) is improper because Yadav “was not published until May 16, 2013, more than three years after the priority date of the ’638 patent.” However, under 35 U.S.C. § 102(e)(1), a published patent application, such as Yadav, is deemed to be prior art as of its filing date, not its publication date as Patent Owner asserts.

“We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses element [1.2] because the evidence cited does not disclose a “first computer system being configured to provide remote control of the first pump or first valve” (i.e., a fluid-handling device). Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but Petitioner has not identified any disclosure of the capability to remotely control fluid-handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, Kahn’s disclosures that Petitioner relies on for allegedly teaching remote control are deficient. We discuss each. First, Petitioner points to the following, “[f]or instance, as illustrated in FIG. 1C, a fluid control device such as a valve 15A is located on the input side of a sen[s]or unit 110.” Ex. 1005, 8:19–21, cited in Pet. 13.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“target value” is part of a command that is sent from a computing device to a server and then to a controller. The controller then receives a measurement of the fluid by a sensor and determines whether the measurement satisfies the “target value.” If the measurement does not satisfy the “target value,” further operations are undertaken. The recited operation sequence makes clear that the plain and ordinary meaning of “target value” is not as Dr. Wooley opines because the particular operating condition that a device is in at a particular time is represented by the measurement taken by the sensor, 11 Some claim language less relevant to construing “target value” was omitted for ease of reference. which the controller then uses to determine whether the measurement satisfies the “target value.” Additionally, claim 1 recites that the “target value” is sent as part of a command to the controller. The “target value” is not sent to the controller from the sensor, as might be expected if the plain and ordinary meaning of “target value” were as Dr. Wooley opines. Petitioner and Dr. Wooley’s construction would also result in “target value” meaning effectively the same thing as the measurement of the fluid by the sensor, a concept that is separately recited in claim 1 and to which the “target value” is compared. The Specification of the ’680 patent does not support Petitioner’s understanding of the plain and ordinary meaning of “target value.” Although the Specification does not recite “target value,” it recites “target state,” and describes “target state” sufficiently to understand the plain and ordinary meaning of “target” as used in “target value” and “target state.” In particular, the ’680 patent explains that “[i]n some embodiments, the process 104 includes receiving, via a network interface, from a remote user device, (e.g., via a command-center server) a command to change a state of a fluid-handling device to a target state.” Ex. 1001, 11:48–51. This portion reflects that the command is seeking to change a state of a fluid-handling device to a target state. In other words, the “target value” or “target state” is not generally “the particular operating condition that a device is in at a particular time”; rather, it is a value or state that the fluid-handling device is desired to be in, as Patent Owner and Dr. Durham explain. Additionally, just as claim 1 recites a directional component for the “target value” to be sent to the controller in a command, so too does the Specification describe a “target state” as being sent in a command from a remote user device. Thus, the Specification clearly supports the plain and ordinary meaning proposed by Patent Owner and Dr. Durham and not the plain and ordinary meaning proposed by Petitioner and Dr. Wooley. slip op. at 14

“time-stamped process data, report exception therein to the remote host, and extract and transmit time-stamped process data to the remote host.” Ex. 1005, Abst. (emphases added). Almadi explains that its remote field systems must include a plurality of controller units “to issue commands to, and gather and process data from a plurality of field devices, including remote systems and instruments, . . . [and] a database server for the storage of process data retrieved from the remote subsystems and instruments.” Id. at 2:22–30 (emphases added). Based on these disclosures, we agree with Patent Owner that Petitioner has not established that Almadi discloses element [1.4]. Specifically, the teachings from Almadi identified by Petitioner refer to process data, which is data retrieved from the remote subsystems/field devices. Thus, we understand that Almadi’s teaching—of using an Ethernet switch to transmit “process data”—describes transmitting data from the remote subsystems/field devices. See Ex. 1005, 3:13–17, cited in Pet. 15. But claim 1 and particularly element [1.4], recites “sending, with the server, the target value to the network address [which identifies a controller of the fluid-handling device13] via the network,” which is different than sending process data from the field devices to the remote host or database server for storage.” slip op. at 19

“We secondly conclude a POSITA would have had at least two years of experience designing and/or developing CMP technology per Patent Owner’s formulation, but we reject Patent Owner’s additional contention that this experience must include designing and/or developing pad dressers specifically. The ’270 patent claims are directed to the structure of a pad dresser, not to a method of making a pad dresser. See Ex. 1001, 17:35– 18:38. According to the ’270 patent specification, the claimed pad dresser structure is designed to condition a polishing pad so the pad may be used to attain “high performance levels in aspects such as uniformity of polished wafer, smoothness of the IC circuitry, removal rate for productivity, longevity of consumables for CMP economics, etc.” during a CMP process. Id. at 1:20–24 (Background of the Invention). Thus, the ’270 patent’s invention generally focuses on optimizing a pad dresser structure to achieve desired results in a CMP process, not necessarily on how to manufacture a pad dresser. As such, we reject Petitioner’s POSITA formulation requiring “experience in the field of integrated circuit processing and fabrication techniques” (Pet. 19) as too generic in the context of the ’270 patent’s claimed invention. We also conclude, in view of the ’270 patent disclosures discussed above, that Dr. Tsai’s opinion that ordinary skill requires experience with manufacturing pad dressers (see Ex. 2011 ¶ 28) is too conclusory and lacking in evidentiary support to be persuasive.

“We determine Dr. Shanfield has sufficient education and experience to qualify as a person of ordinary skill in the art pertaining to the ’270 patent. Dr. Shanfield’s Ph.D. in physics satisfies the educational prerequisite of at least a bachelor’s degree in an engineering related field such as physics. See Ex. 1002 ¶ 2, App. A. Furthermore, his advanced degree (Ph.D. in physics) versus ordinary skill (a bachelor’s degree in an engineering related field) provides considerable leeway when turning to the experiential component for ordinary skill. Nonetheless, Dr. Shanfield also has at least two years of experience with designing and developing CMP technology per the experience prerequisite, as follows. Dr. Shanfield worked at Raytheon Corporation for over 10 years, during which he “worked directly with engineers in the selection, installation, and optimization of several chemo-mechanical polishing systems (CMP), including analysis of operational maintenance and performance monitoring,” and he “directly participated in establishing the required metrology (optical thickness monitoring) for maintaining polishing uniformity standards.” Ex. 1002 ¶ 3 (emphasis added). He later joined Draper Laboratory in 2003, where he currently is the Division Leader of Advanced Hardware Development. See id. ¶ 5. During Dr. Shanfield’s time at Draper, the laboratory “acquired several semiconductor-grade CMP systems for the purpose of fabricating multi-chip modules and for planarization operations in MEMS devices,” and he was “involved in their operation and optimization.” Id. (emphasis added). When asked during a deposition whether he is “an expert in CMP equipment design,” Dr. Shanfield stated he is “very familiar with the design of CMP equipment” because he has “seen many systems” and “installed or supervised the installation of systems.” Ex. 2003, 17:22–19:3. He testified he has “designed apparatus that worked with CMP equipment” although he has not “designed the CMP equipment itself.” Id. at 18:13–19. As an example of being “involved in the manufacture of CMP pad dressers” specifically, Dr. Shanfield stated that during his time at Raytheon, he worked with other professionals “to use the CMP system to process MEMS, M-E-M-S, devices” which “needed a certain kind of planarization process [that] required constant conditioning,” so the team “had to try to fabricate something that would provide conditioning that would last longer.” Id. at 19:4–20:9.

“In his deposition testimony, Dr. Tsai testifies that the Sung ’026 patent application publication “intends to make a diamond disk that has all the protrusion[s] with identical heights and with the same orientation.” Ex. 1049, 50:2–4. Dr. Tsai also testified that “[i]n addition, [Sung ’026] also intends to control the depths of penetrating into the pad. For example, if I want to penetrate 10 micron into the pad, then the protrusion height should be at least 10 micron.” Id. at 50:10–13. So, contrary to Dr. Tsai’s Declaration testimony in Ex. 2011 ¶ 69, Dr. Tsai clarifies in his deposition testimony that Sung ’026 intends to combine three distinct aspects or embodiments. He testifies that “first one is that you need to have the same orientation, same shape so you can have the consistency; and No. 2, you would like to have the same height; and No. 3, you would like to control the penetration depths.” Ex. 1049, 51:2–6.

“According to Patent Owner, Petitioner’s argument is that “several distinct portions of Sung ’026 purportedly, when viewed together, disclose an embodiment that satisfies the recitation of Claim Limitation [1C].” Id. at 20.

It is Petitioner’s position that Dr. Tsai’s deposition testimony supports Petitioner’s assertions that Sung ’026 anticipates independent claim 1 because the various alleged “individual embodiments” are part of a unified whole that overcome the circumstances discussed in Net MoneyIN. In his deposition testimony, Dr. Tsai testifies that the Sung ’026 patent application publication “intends to make a diamond disk that has all the protrusion[s] with identical heights and with the same orientation.” Ex. 1049, 50:2–4. Dr. Tsai also testified that “[i]n addition, [Sung ’026] also intends to control the depths of penetrating into the pad. For example, if I want to penetrate 10 micron into the pad, then the protrusion height should be at least 10 micron.” Id. at 50:10–13. So, contrary to Dr. Tsai’s Declaration testimony in Ex. 2011 ¶ 69, Dr. Tsai clarifies in his deposition testimony that Sung ’026 intends to combine three distinct aspects or embodiments. He testifies that “first one is that you need to have the same orientation, same shape so you can have the consistency; and No. 2, you would like to have the same height; and No. 3, you would like to control the penetration depths.” Ex. 1049, 51:2–6. Dr. Tsai was then asked “[s]o Sung ’026 is trying to combine all three of those together, correct?” Id. at 51:9– 10. His answer was “[t]hat’s correct, because if you can have a very good control of those, then -- and that time period back then, then you can make a very perfect diamond disk.” Id. at 51:11–13. Based on the evidence as discussed above, we determine that Sung ’026 discloses the elements and limitations in clause 1[C]. In particular, we credit Dr. Shanfield’s testimony (as summarized above) over Dr. Tsai’s declaration testimony, because Dr. Tsai’s deposition testimony essentially agreed with Dr. Shanfield that Sung ’026 discloses all the aspects recited in claim 1 together in a single embodiment.” slip op. at 48

“Here, it is undisputed that Skechers was neither a party to the earlier lululemon IPR nor had ever before challenged the claims of the ’484 patent. Instead, in an attempt to demonstrate a significant relationship between Skechers and lululemon that might justify application of the General Plastic framework, Nike’s sole argument is that “Skechers created a relationship with lululemon by openly admitting that it used lululemon’s petition as a roadmap” and that “[t]his admitted roadmapping creates an implicit relationship between Skechers and lululemon.” PO Sur-Reply 2. We reject the notion that “roadmapping” alone creates a significant relationship. As noted in Videndum, a second petitioner’s reliance on a first petitioner’s earlier-filed petition, “even ‘as a menu or road map,’ is not sufficient to create a significant relationship that favors denial under the first General Plastic factor.” Videndum, at *2 (emphasis added); see also Ford, at *2 (rejecting patent owner’s argument that Ford’s use of prior Volkswagen and Dell IPRs “as a roadmap for its Petition” was sufficient to create “an ‘implicit’ relationship”). In other words, absent some evidence of a non-mandated7 collaboration between Skechers and lululemon (such as proof of a licensing or other technology-sharing agreement regarding the accused product), Skechers’ use of arguments and evidence similar to those in the earlier lululemon IPR does not create a significant relationship. Nor does it appear that Nike could reasonably establish such a relationship given that Skechers is a direct competitor of lululemon, was sued on an entirely different product than lululemon, and was not sued until after lululemon had already sought inter partes review of the challenged patent.

“In particular, the Board has already performed a detailed analysis of the ’484 patent, including construing the claim terms and applying two of the prior art references—Dua and Hong—that form the primary ground here. As such, the Board is much further along in understanding the challenged claims and the parties’ dispute over their validity than the district court in the parallel litigation. And even if the Final Decision in the lululemon IPR is reversed or remanded on appeal, the Board’s considerable experience with the relevant issues remains. Thus, the fact that the Board has already expended considerable time and resources in deciding the validity of the challenged claims, whereas the district court has not, weighs heavily in favor of institution.10 Indeed, in staying the parallel litigation, the district court expressly recognized the lack of any significant investment by the parties or the court— - “[D]iscovery is still in the early stages.” - “The parties . . . have not yet taken any depositions, any third party discovery, or any expert discovery. . . . Accordingly, this case remains in its early stages.” - “Despite [the parties’] significant work [on claim construction], . . . there is more work ahead of the parties and the Court than behind.”” slip op. at 9

“Skechers notes that “[d]uring the parallel litigation, the parties agreed that the term ‘central portion having a domed, three-dimensional structure’ means ‘central portion having a domed, three-dimensional structure formed during the flat-knitting process, and not afterward’” and that “in the lululemon IPR . . . the Board adopted [this] as its construction.” Pet. 11 (citing Ex. 1005, 2; Ex. 1021, 6) (emphasis added). Nike agrees with that construction. See Prelim. Resp. 11–12 (quoting Pet. 11).

“d. Overlap of Issues “[I]f the petition includes the same or substantially the same claims, grounds, arguments, and evidence as presented in the parallel proceeding, this fact has favored denial.” Fintiv, Paper 11 at 12. “Conversely, if the petition includes materially different grounds, arguments, and/or evidence than those presented in the district court, this fact has tended to weigh against exercising discretion to deny institution under NHK.” Id. at 12–13. Concerns about the degree of overlap may be mitigated where a petitioner agrees not to pursue in the parallel district court litigation the grounds advanced in the petition. Sand Revolution II, LLC v. Cont’l Intermodal Grp.–Trucking LLC, IPR2019-01393, Paper 24 at 11–12 (PTAB June 16, 2020) (informative). The Board suggested that a broader stipulation such as one stipulating that the petitioner “would not pursue any ground raised or that could have been reasonably raised in an IPR, i.e., any ground that could be raised under §§ 102 or 103 on the basis of prior art patents or printed publications” would better address concerns relating to overlapping issues. Id. at 12 n.5. Here, Petitioner’s stipulation is broader—Petitioner stipulates that, if the Board institutes IPR in this proceeding on the grounds presented in the Petition, Petitioners will not pursue an invalidity defense in the [Texas Litigation] that the patent claims subject to the instituted IPR are invalid based on the grounds that were raised or any grounds Petitioner[] reasonably could have raised in the IPR. Prelim. Reply 3. Petitioner’s stipulation is similar to that provided in Sotera Wireless, Inc. v. Masimo Corp., IPR2020-01019, Paper 12, 18–19 (PTAB Dec. 1, 2020) (precedential in relevant part), which was found to obviate much, if not all, of any potential overlap between the issues in the proceeding and the district court proceeding. See Prelim. Sur-reply 3 (acknowledging that “Petitioner[] offered a Sotera stipulation.”) Accordingly, the facts underlying this factor weigh strongly against exercising our discretion to deny institution.” slip op. at 13

“Patent Owner argues that the Petition improperly presents voluminous and excessive grounds challenging the claims of the ’878 patent. Prelim. Resp. 10–14. Patent Owner argues that the twenty distinct grounds set forth in the Petition alone is reason to deny institution. Id. at 11. Patent Owner argues that Petitioner’s showing regarding the VFD, switchgear, and enclosure recitations of claim 1 require us to “pick-and-choose” which “prior art evidence” is being applied. Id. at 14. We are not persuaded that the Petition sets forth such voluminous or excessive grounds asserting unpatentability that we should deny institution. Although Petitioner does set forth twenty grounds, sixteen of the grounds are directed to a single dependent claim. See Pet. 16–17. And of the four grounds challenging independent claim 1, Petitioner relies primarily on the combined teachings of Morris and Oehring IV to disclose or teach most of the claim recitations, relying on Premset Catalog and Premset Brochure to teach front-aligned, shielded cable connections and on Payne to provide an alternate teaching of using a common support structure. See Pet. 48–51, 70–74. The instant Petition is quite unlike those in the decisions cited by Patent Owner, which dealt with petitions asserting challenges containing multiple instances of “and/or” that resulted in hundreds of challenges or asserting multiple challenges grouped together in an indiscernible claim chart. See Prelim. Resp. 10 (citing Adaptics Ltd. v. Perfect Co., IPR2018-01596, Paper 20 (PTAB Mar. 6, 2019) (informative); Uber Techs., Inc. v.

“2026. This date is nearly five months prior to the date on which the final written decision would be due if trial were instituted in this proceeding. And, even if we assume Petitioner’s alleged February–March 2026 trial date, this date too is several months prior to the projected final written decision deadline. As such, it is unlikely that a final written decision in this proceeding would issue before trial in the district court, unless the trial was delayed or rescheduled for a later time.
