  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Patent Owner proposes that a person of ordinary skill in the art “would have a Bachelor of Science degree in Electrical Engineering, Computer Engineering, Computer Science, Human Computer Interaction, or a related technical field, with at least one year of experience working in the field of user interfaces and/or content management.” PO Resp. 11 (citing Ex. 2040 ¶ 53). The Decision on Institution adopted Petitioner’s proposed level of ordinary skill in the art. Inst. Dec. 10. We find Patent Owner’s stated level to be less precise than that proposed by Petitioner in that the modifier “at least” used by Patent owner imposes no upper bound on the amount of experience possessed by one of ordinary skill in the art. Also, Patent Owner states: “The difference between the Board’s definition and Patent Owner’s (EX2040. ¶53) does not change the arguments set forth herein.” PO Resp. 11.

    “PO Resp. 30–31 (Figure 26 omitted). In its Reply, Petitioner still does not provide an articulated reason for placing user profile selection buttons, labeled with user names, within Horn’s panes 2601 or 2602. Reply 12–14. Although Horn does describe personalized profile, Petitioner points to no disclosure of Horn as to how a user would have selected his or her own profile from among a plurality of user profiles. Petitioner presents no reason for placing these user profile selection buttons, labeled with user names, gleaned from or suggested by Baumgartner, within either pane 2601 or pane 2602 in Horn’s workspace view. Further, pane 2602 contains “a list of all collections defined by MFS and the user,” and pane 2601 lists the source examined by the user to create his or her collections. Ex. 1005, 19:41–46. That disclosure suggests the contents of panes 2601 and 2602 are tied to one particular user. No rational basis is articulated by Petitioner to place user profile selection buttons within these panes which appear to be in the profile space of one user. For the foregoing reasons, Petitioner has not adequately accounted for limitation 16[b].” slip op. at 22

  • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

    “The test for sufficiency of a written description under 35 U.S.C. § 112 is whether the earlier application’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The specification must “clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed.” Id. The Court of Appeals for the Federal Circuit has explained: One shows that one is “in possession” of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious. Id. (“[T]he applicant must also convey to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention. The invention is, for purposes of the ‘written description’ inquiry, whatever is now claimed.”) (emphasis in original). One does that by such descriptive means as words, structures, figures, diagrams, formulas, etc., that fully set forth the claimed invention. Although the exact terms need not be used in haec verba, see Eiselstein v. Frank, 52 F.3d 1035, 1038, 34 USPQ2d 1467, 1470 (Fed.Cir.1995) (“[T]he prior application need not describe the claimed subject matter in exactly the same terms as used in the claims. . . .”), the specification must contain an equivalent description of the claimed subject matter.

    “We do not reach a resolution on the issue of relative cost between a wired LAN versus a wireless LAN, because Petitioner’s assertion that wireless LANs “were often cheaper and easier to install” is nebulous by use of the imprecise word “often.” “Often” cheaper permits “often” not cheaper. Much depends on how many access points would exist in the wired LAN. Petitioner does not discuss that consideration in the context of Horn. Also, we are persuaded by Petitioner’s other stated reasons for implementing Horn’s LAN as a wireless LAN: (1) that a wireless LAN can be more convenient to users, and (2) Baumgartner provides adequate motivation by disclosing transmission of video from server 36 via communications network 34 such as the Internet over link 48 implemented wirelessly to user computer equipment 22 such as a personal computer. Pet. 29–32. We are persuaded that a wireless LAN provides more user convenience by enabling the user equipment accessing the external network to be flexibly located within the range of the LAN without need to have wires installed to run to those locations. That is true whether there is only one user equipment or there are multiple user equipment, one per user. In the case of only one user equipment, the user can access the external network from a wide range of locations and change that location flexibly. In the case of multiple user equipment, one per user, each user can access the external network from his or her own preferred location, and also change that preference at any time without regard to whether wires have been installed to the preferred location.” slip op. at 22

    “13 The Court was very critical of Dr. Wobbrock’s testimony in the related district court case. See generally Ex. 1026 (September 18, 2025 Order). With regard to the ’086 patent, the Court found that Dr. Wobbrock’s testimony was not based on any record evidence (id. at 7, 9), arbitrary (id.), contrary to the evidence (id. at 7–8), unjustified (id. at 8), ipse dixit (id. at 9), conclusory (three times) (id.), insufficient to support a jury verdict (three times) (id. at 9, 27), untethered from the Specification (three times) (id. at 28, 30, 31), inconsistent (id. at 29), insufficient to support his opinion (id. at 29–30), unsupported (id. at 30), and not to be credited by a reasonable jury (id. at 31). We have considered this criticism of Dr. Wobbrock’s testimony in view of the September 16, 2025, Memorandum to the Members of the Patent Trial and Appeal Board on the subject of “PTAB consideration of prior findings of fact and conclusions of law” (available at: https://www.uspto.gov/sites/default/files/documents/Memo_re_prior_finding s_of_fact_and_conclusions_of_law_9_16_25.pdf?utm_campaign=subscripti oncenter&utm_content=&utm_medium=email&utm_name=&utm_source=g ovdelivery&utm_term=) and in light of the case law (see, e.g., N.L.R.B. v. Pittsburgh S.S. Co., 337 U.S. 656, 659 (1949) (“[I]n the determination of litigated facts, the testimony of one who has been found unreliable as to one issue may properly be accorded little weight as to the next.”). We have similarly found Dr. Wobbrock’s testimony to be contrary to the plain and ordinary meaning of the claims, untethered from the Specification, unsupported by the evidence, inconsistent, arbitrary, and conclusory. We accord the testimony of Dr. Wobbrock little or no weight. We view the testimony of Petitioner’s expert, Dr. Nielson, as more credible and persuasive as it tracks more closely with the ’086 patent and the cited art. EcoFactor, Inc. v.

    “We find no support in the language of claim 1 for construing the “first registering mode” and the “second registering mode” as “operating modes,” or as “different operational states,” or “sub-operating modes of the ‘said registering mode’” as contended by Patent Owner. There is no express statement in claim 1 that the “first registering mode” and the “second registering mode” are “operating modes,” or are “different operational states,” or are “sub-operating modes of the ‘said registering mode.’” The language of claim 1 is clear that the only two “operating modes” explicitly recited in claim 1 are the “identification mode” and the “registration mode.” Claim 1 recites that these two “modes” are “operating modes,” but does not recite that the “first registering mode” and the “second registering mode” are “operating modes.” The language of claim 1 cannot be read to include the requirements that the “first registering mode” and the “second registering mode” are “operating modes,” or are “different operational states,” or are “sub-operating modes of the ‘said registering mode.’” Rather, we agree with Petitioner that the language of limitation 1c that specifically refers to the “registering mode” as an “operating mode” and the language of limitation 1f that refers to the “first registering mode” and the “second registering mode” as “mode[s] for inputting input information” that are “provided in said registering mode” contradicts Patent Owner’s proposed construction that would require the “first” and “second registering mode[s]” to be “different operational states.” The plain and ordinary meaning of the language of claim 1 provides that the “first registering mode” and the “second registering mode” are “mode[s] for inputting input information” that are “provided in said registering mode” which is one of the two delineated “operating modes.” Both “first” and “second” “registering mode[s]” ”for inputting input information” are recited as “provided in said registering mode,” a single “operating mode.”17” slip op. at 17

    “Both references are directed to allowing users to input information via touchsurface technology and are analogous art to the ’086 patent. . . . [A] POSITA would have found Rogers and Rosenberg to be compatible because of the technical similarity of their teachings, and a POSITA would have further recognized that Rosenberg’s finger orientation disclosures, applied to Rogers’ graphical passcode disclosures, would facilitate a “natural and intuitive” means of implementing the teachings of Rogers. A POSITA therefore would have been motivated to look to Rosenberg to improve Rogers, and vice-versa. . . . A POSITA . . . would have considered the disclosures in Rosenberg and been motivated to modify Rogers’ “large fingertip and a small stylus tip” example so that it instead used the “natural and intuitive” finger pad versus finger end distinction discussed in Rosenberg. A POSITA would have found this modification to be a simple substitution of elements well known in the art and would have had a reasonable expectation of success in achieving the benefits disclosed in Rosenberg by making the modification, which involved only routine skill. . . . [A]dding finger end and finger pad touch detection to Rogers would involve no more than applying a known technique (i.e., finger end and finger pad touch detection/distinction as taught by Rosenberg) to a known device ready for improvement (Rogers’ apparatus having “large fingertip and a small stylus tip” capabilities) to yield predictable results (simple to use touch screen interface with multipoint targeting and multi-finger gesturing). . . . It also would have been obvious to combine Rogers with Rosenberg because both references disclose touch screen interfaces that detect a contact area of a finger. . . . A POSITA would have considered Rosenberg’s disclosures and been motivated to modify the “graphical passcode” features of Rogers so that the disclosed device is capable of detecting information input by a pad or end of a finger, because it would provide a “generally easily distinguishable” basis upon which to program the device disclosed in Rogers to detect a “measurable parameter” based on “contact area.” A POSITA would have further recognized that these features of Rogers and Rosenberg could be successfully combined because both references teach a “calibration” mode in which the user trains the device to recognize a specific range of input parameters that allows for some variation in input while remaining within acceptable tolerances. . . .

    “3. Motivation to Combine Buibas and Sinyavskiy Petitioner argues that “it would have been obvious to partition Buibas’[s] spiking networks according to the specific techniques disclosed in Sinyavskiy” for multiple reasons. Pet. 13 (citing Ex. 1005 ¶¶ 71–72, 85, 92, 179–203; Ex. 1006 ¶¶ 12, 185, 188, 191, Fig. 6A; Ex. 1003 ¶ 63). First, Petitioner asserts, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to parallelize task execution on the robot and improve learning capabilities (e.g., through faster learning, greater computing efficiency, and task-specific learning models) of the Buibas mobile robotic apparatus as described by Sinyavskiy and discussed by Dr. Janet.” Id. (citing Ex. 1003 ¶ 64). Second, Petitioner contends, “partitioning Buibas’[s] robotic brain as suggested by Sinyavskiy would have beneficially expanded the range of tasks that the robot could perform by dedicating partitions to specialized tasks.” Id. at 13– 14 (citing Ex. 1006 ¶¶ 12, 185, 188, Fig. 6A; Ex. 1005 ¶¶ 71–72, 85, 92, 179–205; Ex. 1003 ¶ 65). Third, Petitioner argues, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to permit unused partitions or unused resources in the partitions to be reassigned for different tasks,” which would allow for a network processing apparatus that has increased processing capability for the same network capacity while also having a lower cost, size and power consumption. Id. at 14 (citing Ex. 1006 ¶¶ 190–192, 105, 34, code (57); Ex. 1003 ¶ 66). Fourth, Petitioner argues that “Buibas briefly mentions that its spiking neural networks can be partitioned but discloses little detail about the partitioning,” which would invite one of ordinary skill to turn to other references, such as Sinyavskiy, for additional detail on how to implement partitioning. Pet. 14–15 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 67). Fifth, Petitioner asserts, combining Buibas and Sinyavskiy would merely “involve[] the application of known techniques (e.g., Sinyavskiy’s partitioned neural network) to a known system (e.g., Buibas’[s] mobile robot and robotic brain) to yield predictable results (e.g., Buibas’[s] robot using a spiking neural network partitioned as taught in Sinyavskiy),” particularly because “the partitioning of the Buibas neural network is reminiscent of Recurrent Fuzzy Neural Networks (RFNNs) that were already commonplace at the end of the 1990’s.” Id. at 15 (citing Ex. 1003 ¶ 68). Finally, Petitioner contends, the proposed combination merely involves “use of known techniques (e.g., Sinyavskiy’s partitioned neural network) to improve a similar system (e.g., Buibas’[s] mobile robot and robotic brain).” Id. (citing Ex. 1003 ¶ 69). Petitioner further argues that one of ordinary skill “would have reasonably expected success implementing the combination, especially as Buibas and Sinyavskiy describe highly similar systems involving spiking neural networks used for training/operating robots.” Pet. 15–16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). Indeed, Petitioner contends, “Buibas itself confirms that its spiking neural network can be partitioned, while Sinyavskiy provides the details for doing so.” Id. at 16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70).” slip op. at 14

    “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

    “For purposes of this Decision, we adopt Petitioner’s definition of a POSITA. Petitioner’s witness (Mr. Cook) qualifies as a POSITA under this definition, and, therefore, is qualified to opine from the perspective of a POSITA on technical matters included within the areas of expertise prescribed by the definition. As indicated above, Petitioner’s definition of a POSITA does not require education in the field of optics and professional experience designing or analyzing optical apparatus, unlike Patent Owner’s definition. We are aware, however, that Patent Owner’s witness (Dr. Klopp) has more extensive experience with optical systems and methods than Petitioner’s witness (Mr. Cook). Compare Ex 1003 ¶¶ 8–14, Ex. 2005, 39:21–59:17, with Ex. 2003 ¶¶ 3–20, Ex. 2004, 1–2, Ex. 1015, 10:22–13:25. Although Mr. Cook possesses excellent credentials in the field of mechanical engineering, his experience in the design and analysis of optical systems and methods is sparse and insubstantial compared to that of Dr. Klopp. Id. Due to this difference in experience levels, in instances where the witnesses express differing views on factual issues related to optical systems and methods, we will accord more weight to Dr. Klopp’s testimony than to Mr. Cook’s.” slip op. at 8

Tseng does not disclose or teach that light is emitted through the side surface of annular protrusion 383 in a direction perpendicular to the longitudinal axis of the housing. Ex. 1004 ¶ 97. Petitioner’s assertions that this would be the case consist solely of conclusory statements, supported only by citations to Mr. Cook’s declaration. Mr. Cook, however, simply repeats Petitioner’s conclusory statements, without providing sound technical reasoning supported by objective evidence to explain and support his opinions. Ex. 2003 ¶¶ 101– 102, 105, 195–198, 202. We, therefore, accord little weight to Mr. Cook’s opinion on this particular matter because it “merely repeats, verbatim, the conclusory assertion for which it is offered to support,” and “does not cite to any additional supporting evidence or provide any technical reasoning [in] support.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). Furthermore, Mr. Cook’s opinion conflicts with that of Patent Owner’s witness, Dr. Klopp, who opines that a “POSITA would understand from Tseng’s third embodiment that light from the LED would bypass the annular protrusion 383 of outer cliff 381, while transmitting downwardly toward the output face 313.” Compare Ex. 1003 ¶¶ 174–175, 190–194, with Ex. 2003 ¶¶ 101–102, 105. As discussed above, Mr. Cook is qualified to opine from the perspective of a POSITA on technical matters included within the expertise of a person meeting Petitioner’s definition of a POSITA, which do not include optics and optical apparatus. We, therefore, credit Dr. Klopp’s opinion over that of Mr. Cook on this particular factual issue of how it is directly related to optical systems and methods about which Mr. Cook possesses limited relevant experience. See Ex. 1003 ¶¶ 6–15 (experience in communication systems and electronics); Ex. 2005, 55:16–58:19 (design experience with electronics that use indicator lights or fiber-optic communications; no professional experience with light pipes, diffusers, or plumbing fixtures). Dr. Klopp possesses substantial research and professional experience with optical methods, fiber optic light pipes, light guides, diffusers, prisms, and analysis of faucets, spray heads, and plumbing fixtures. See Ex. 2003 ¶¶ 6–10 Supra 8 (discussing weight accorded to conflicting witness testimony); see also Resp. 2–3 (arguing that “Petitioner’s expert, Mr. Cook, is a mechanical engineer with substantial professional experience in electronics for high-voltage power systems and communications, but he has limited experience with the claimed subject matter.”).” slip op. at 34

    “variable data database’ as required by claim 1.” Dec. 22. We discussed and quoted extensively from Petitioner’s expert declaration of Dr. Fox and Patent Owner’s expert declaration of Dr. Malek. Id. at 22–26 (citing Ex. 1003 ¶ 94; Ex. 2001 ¶¶ 68, 70). In reviewing the parties’ submissions, we found that: Halevy’s disclosures are consistent with Patent Owner’s arguments and Dr. Malek’s testimony that Halevy does not teach mapping fields to one another or mapping of fields to one another through SO-properties.

    “Dr. Fox states that “Halevy’s disclosure of a form database in which corresponding fields from different forms on different websites map to the same SO-properties based on the SO-class identified for the form would have been recognized by a POSA as what the ’342 patent refers to as a universal variable map.” Ex. 1003 ¶ 98 (citing Ex. 1001, 17:48– 52). Based on this conclusory opinion, Dr. Fox reasons that Halevy’s form database is a “universal variable map” that must also link computer-readable field identifiers from multiple different websites to each other in the form database, because field identifiers are mapped to the same SO-properties associated with an SO-class.” Id. (emphasis omitted). We observe first that Dr. Fox’s conclusion is not supported by the cited portions of the ’342 patent. In column 17, lines 48–52, the ’342 patent explains that fields or variables may be part of forms, and variations of the data fields or variables “may include a source form, a destination form, a single source to many destination form, many sources to one destination form, cascading forms (e.g., a first form links to a second form which links to a third form, etc.) and so on.” Ex. 1001, 17:48–52. While this portion of the ’342 patent indicates that forms may include variations on fields or variables, it does not describe linking or mapping variables to one another. Ex. 2001 ¶ 75 (“[T]hat portion of the specification does not have anything to do with the definition of a “universal variable map.” Rather, it merely discusses different types of variables and fields that might appear in different types of forms.”). Dec. 28–29. We again referred to the disclosure of the ’342 patent to address evidence in the Petition relied upon by Dr. Fox to support Petitioner’s position. Id. We credited Dr. Malek’s testimony over Dr. Fox’s testimony because Dr. Malek underlined the distinctions between the asserted Belanger-Halevy prior art combination and limitation [1B]. Dec. 28–31. In short, any confusion applying the prior art Belanger-Halevy references to the claim limitation is rooted in the Petition. The Board denied the Petition because the Petition did not demonstrate a reasonable likelihood of showing that Belanger-Halevy discloses or teaches limitation [1B] of the ’342 patent.” slip op. at 5
