In doing so, the diaphragm prevents the passage of milk from reaching the air pump and facilitates generation of negative pressure during operation.

    “device. The ’972 patent expressly defines endpoints broadly “as data sources or sinks.” Ex. 1001, 7:64–67. And the ’972 patent admits that Beel’s Figure 11 discloses the same endpoints depicted in the ’972 patent’s own Figure 4. Id. at 4:28–33, 16:44–67. Beel’s Figure 11 and accompanying description disclose a “[m]ass storage device 12,” a “USB audio device 14,” and a “USB HID device 13” on the peripheral device. Ex. 1005, Fig. 11, ¶¶ 320–323. Patent Owner’s own declarant conceded that a mass storage device is “a type of endpoint” (Ex. 1034, 43:19–21), and that “audio devices are endpoints” (id. at 57:5–61:4). We give reduced weight to Patent Owner’s contrary position to the extent it rests on the premise that a reference cannot disclose an endpoint unless it uses the word “endpoint” (Ex. 2030 ¶ 94; Ex. 1034, 43:19–44:16, 72:18–73:12); a premise that is inconsistent with the ’972 patent’s own broad definition and with the ’972 patent’s admission regarding Beel’s Figure 11. As additional support not separately emphasized by the parties in this connection, we note Dr. Almeroth’s technical explanation that, for data to pass from a functional device to a peripheral device, “both the functional device and the peripheral device must have ‘endpoints’”—a data source and a data sink—reasoning consistent with the ’972 patent’s definition. Ex. 1002 ¶ 125.” slip op. at 27

    “First, we agree with Patent Owner that, under the ordinary meaning of the claim language, the endpoint is an endpoint of the peripheral device, and that it must be “a data source or a data sink which is able to store or emit data, of the functional device exposed or made available on the first peripheral device.” Ex. 1001, 23:11–17. The limitation thus identifies a structure—an endpoint, residing on the peripheral device, that is a source or sink and that corresponds to (is “of”) the functional device—through which the communication recited in subsequent element (g) is carried out. By its terms, it imposes no requirement as to the direction in which data flows; it requires only that the endpoint be a data “source” or a data “sink” that is able to “store or emit” data. The operative transmit-and-receive communication “from the functional device to the processing device via the . . . endpoint” is recited in subsequent element (g), which we take up separately below. The disputed question under this limitation is therefore the structural one: whether Beel discloses, on the peripheral device, an endpoint that is “of the functional device.” Because the inquiry is structural and non-directional, we are not persuaded that the audio-out orientation of Beel’s described embodiment, on which Patent Owner relies, is dispositive of this limitation. device. The ’972 patent expressly defines endpoints broadly “as data sources or sinks.” Ex. 1001, 7:64–67. And the ’972 patent admits that Beel’s Figure 11 discloses the same endpoints depicted in the ’972 patent’s own Figure 4. Id. at 4:28–33, 16:44–67. Beel’s Figure 11 and accompanying description disclose a “[m]ass storage device 12,” a “USB audio device 14,” and a “USB HID device 13” on the peripheral device. Ex. 1005, Fig. 11, ¶¶ 320–323. Patent Owner’s own declarant conceded that a mass storage device is “a type of endpoint” (Ex. 1034, 43:19–21), and that “audio devices are endpoints” (id. at 57:5–61:4). We give reduced weight to Patent Owner’s contrary position to the extent it rests on the premise that a reference cannot disclose an endpoint unless it uses the word “endpoint” (Ex. 2030 ¶ 94; Ex. 1034, 43:19–44:16, 72:18–73:12); a premise that is inconsistent with the ’972 patent’s own broad definition and with the ’972 patent’s admission regarding Beel’s Figure 11. As additional support not separately emphasized by the parties in this connection, we note Dr. Almeroth’s technical explanation that, for data to pass from a functional device to a peripheral device, “both the functional device and the peripheral device must have ‘endpoints’”—a data source and a data sink—reasoning consistent with the ’972 patent’s definition. Ex. 1002 ¶ 125. Third, we find that the endpoint Beel discloses is a data source or a data sink that is “able to store or emit data, of the functional device.” We begin with the words of the limitation. The endpoint need only be “able to store or emit data”—language of capability, not a requirement that particular data actually traverse the endpoint in operation, and still less in a particular direction. And the endpoint is defined by the character of the data it handles: it is “a data source or a data sink,” which the ’972 patent instructs An audio endpoint, so understood, is characterized as an audio source or sink; its structure is not tied to any single instance of an audio device. On that understanding, Beel’s disclosure establishes the required capability directly. Beel discloses that “audio data is captured through a virtual sound card interface added as a logical device over the physical interface provided in the peripheral device,” Ex. 1005 ¶ 43, that the peripheral device “acts as a composite device comprising for instance a (virtual) audio speaker device,” id. ¶ 317, and that “audio data is captured at this interface . . . internally in the peripheral device 32” and streamed over the communications network, id. ¶ 319. Beel thus shows the endpoint on the peripheral device actually storing and emitting audio—and, correspondingly, video—data, which is the very type of data produced and consumed by the audio/visual functional devices connected to the base unit, including the microphones, cameras, speakers, and displays. Id. ¶ 120. An endpoint shown to store or emit audio and video data is necessarily one that is “able to store or emit” such data; the capability the limitation requires is thus established by Beel’s disclosure.” slip op. at 26

After discussing why KR996 and Bares are analogous art to the claimed invention, Petitioner states that one of ordinary skill in the art “would have been motivated to combine the teachings of Bares with KR996 to produce a predictable and beneficial configuration of a tracked vehicle” in that “[t]he simple substitution of Bares’ track assembly for the wheels in the KR996 vehicle would have been predictable with a reasonable expectation of success that both KR996 and Bares relate to similar vehicle types with a similar mainframe having a drive mechanism attached thereto.” Pet. 63 (citing Velinsky Pet.

    “probative and cogent evidence in the record” and “may often establish that an invention appearing to have been obvious in light of the prior art was not.” Transocean Offshore Deepwater Drilling, Inc. v. Maersk Drilling USA, Inc., 699 F.3d 1340, 1349 (Fed. Cir. 2012). Thus, notwithstanding what the teachings of the prior art would have suggested to one skilled in the art, secondary considerations (objective evidence of non-obviousness) may lead to a conclusion that the challenged claims would not have been obvious. In re Piasecki, 745 F.2d 1468, 1471–72 (Fed. Cir. 1984). Our obviousness analysis includes consideration and weighing of Patent Owner’s objective indicia of non-obviousness. In order to accord substantial weight to secondary considerations in an obviousness analysis, “the evidence of secondary considerations must have a ‘nexus’ to the claims, i.e., there must be ‘a legally and factually sufficient connection’ between the evidence and the patented invention.” Henny Penny Corp. v. Frymaster LLC, 938 F.3d 1324, 1332 (Fed. Cir. 2019) (quoting Demaco Corp. v. F. Von Langsdorff Licensing Ltd., 851 F.2d 1387, 1392 (Fed. Cir. 1988)); Quanergy Sys., Inc. v. Velodyne Lidar USA, Inc., 24 F.4th 1406, 1417 (Fed. Cir. 2022). Although the patent owner bears the initial burden of proving a nexus (WMS Gaming Inc. v. Int’l Game Tech., 184 F.3d 1339, 1359 (Fed. Cir. 1999)), a presumption of nexus may be appropriate if the patent owner shows “the asserted objective evidence is tied to a specific product and that product ‘embodies the claimed features, and is coextensive with them.’” Polaris Indus, Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018) (quoting Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1130 (Fed. Cir. 2000) (emphasis added)); Quanergy, 24 F.4th at 1417. On the other hand, “[w]hen the [product] is not coextensive with the patented invention—for example, if the patented invention is only a component of a commercially successful machine or process,” the patent owner is not entitled to a presumption of nexus. Demaco, 851 F.2d at 1392. A patent owner may establish nexus, either through (1) the use of a rebuttable presumption that arises when certain conditions are met or (2) a direct showing of nexus. In the first, a patent owner may rely on a rebuttable presumption of nexus as follows:” slip op. at 43

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

    “Patent Owner’s arguments are unpersuasive. We are not persuaded that these differences between Kaplan, Ahmed, and Deforche are dispositive. To the contrary, we find the differences establish why a POSITA would have further modified Kaplan and Ahmed with the teachings of Deforche. Deforche expressly teaches that a disadvantage of wireless modems is that they require installation of an appropriate driver before applications running on the computer device can use the functionality of the wireless modem to connect to wireless networks. Ex. 1030 ¶¶ 2–3. Deforche solves this problem by using the processing device’s pre-installed drivers, which can be for a human interface device, to set up a modem/host communication interface for communication. Id. ¶¶ 4, 9. Because “[d]ata traffic from the computer device towards the wireless communication network and vice versa is routed over this modem/host communication interface and uses the generic communication protocol provided by the preinstalled generic driver,” Deforche states this “has the advantage that the need for a specific driver for the communication between the wireless modem device and the computer device can avoided” and “the advantage that a user can use the wireless modem device on a computer device on which he has no administrator rights, i.e. a computer specific driver for the wireless modem device.” Id. ¶ 9. “The motivation-to-combine analysis is a flexible one. Any need or problem known in the field of endeavor at the time of and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1379 (Fed. Cir. 2023) (internal quotations omitted). As the Federal Circuit held, “[t]here is a motivation to combine when a known technique has been used to improve one device, and a [skilled artisan] would recognize that it would improve similar devices in the same way.” Intel Corp., 61 F.4th at 1380. Here, Deforche establishes that utilizing an operating system’s preinstalled generic driver to provide a generic protocol communications between the processing device and a peripheral device was known for improving wireless modems because it does not require administrator rights and a specific driver to be installed to enable communications between the wireless modem device and the processing device.” slip op. at 20

    “A person of ordinary skill in the art (“POSITA”) with respect to the subject matter of the ’698 patent at the time of the priority date, March 11, 2004, would have had an undergraduate degree in mechanical engineering, or other technical training in product design or equivalent work experience. This person would also possess at least one year of experience in developing and/or evaluating mechanical aspects of fluid systems. I consider myself a person of ordinary skill in the art under this definition. Ex. 1004 ¶ 28. Patent Owner argues: A POSITA in the field to which the ’698 Patent is directed would have had at least a Bachelor of Science degree in mechanical engineering or a related field or, as a substitute, at least two years of work or research experience in the design or development of toilet products, parts, and accessories. PO Resp. 6. We adopt Patent Owner’s proposed definition of a POSITA, as it is consistent with the ’698 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Petitioner responds that “the claim language of the ’698 Patent discusses adjusting the water flow, not specifically the ‘flow rate.’” Pet. Reply 13. We are not persuaded by Patent Owner, and the conclusory testimony of Mr. Jobin (Ex. 2013 ¶ 97), that because the Flow Limitations “relate” to water flow through the bowl fill valve, that this necessarily means that the flow rate must be adjusted. As Petitioner points out, neither the term “flowrate” nor any similar term appears in any of the Flow Limitations. Thus, the plain language of the Flow Limitations requires that, contrary to Patent Owner’s position, the claim limitation should not be restricted to adjustments to “flow rate.”” slip op. at 14

    “Petitioner argues that Limitations 8B and 12B are directed to the configuration or structure of the bowl fill valve outlet port. Pet. Reply 2–4. According to Petitioner, because Limitations 8B and 12B do recite an overflow tube, the overflow tube is not separately claimed and is recited solely to define the function of the outlet port on the bowl fill valve. Id. at 3. Petitioner, thus, argues that an overflow tube is not separately claimed as a structural element, and that, to meet Limitations 8B and 12B, it is sufficient to show that the prior art discloses a bowl fill valve with an outlet port that is configured to attach directly to a tube that provides water from the outlet port to an overflow tube. Id. at 4. In contrast, Patent Owner argues that Limitations 8B and 12B separately claim the overflow tube, and that Petitioner must show that the prior art discloses a tube that transfers water from the bowl fill valve outlet port to the toilet tank overflow tube. PO Resp. 10–11; PO Sur-reply 2–3. We disagree with Patent Owner, because claims 8 and 12, on their face, require “bowl fill valve outlet port,” but do not require or recite an “overflow tube” as an element of the claimed “bowl fill valve.” When a structure is claimed as “configured to” perform a particular function, it generally requires a structure that is designed to perform the particular function claimed, i.e., it requires more than the mere capability of performing that function. See Aspex Eyewear, Inc. v. Marchon Eyewear, Inc., 672 F.3d 1335, 1349 (Fed. Cir. 2012) (claim language including the phrase “adapted to” is to be construed consistent with “configured to” language and requires that the structure must be “designed or configured to accomplish the specified objective, not simply that [it] can be made to serve that purpose.”); see also In re Giannelli, 739 F.3d 1375, 1379 (Fed. Cir. 2014). The plain language of Limitations 8B and 12B is clearly directed to the configuration of the bowl fill valve outlet port, in that these limitations recite “a bowl fill valve outlet port configured to.”8 The recited function is “attach directly to a tube that provides water from the bowl fill valve outlet port to an overflow tube.” The overflow tube is recited as part of the function in a clause identifying the tube to which the bowl fill valve outlet port is configured to attached — “that provides water from the bowl fill valve outlet port to an overflow tube.” The overflow tube, thus, is recited as part of the function defining the required structure of the bowl fill outlet port and is not separately claimed.” slip op. at 16
