    “We have reviewed the cited testimony of Clearwater’s expert, including their calculations for arriving at a coat weight in Nakagawa that falls within the claimed range. See Ex. 1003 ¶¶ 132–33. We find that testimony, which is unrebutted, both credible and supported by the evidence of record. Thus, in light of Clearwater’s contentions, the cited portions of Nakagawa, and the unrebutted testimony of Clearwater’s expert, we are persuaded that Nakagawa discloses or otherwise suggests each and every element of claim 1. See Pet. 45–54, 60–64. Clearwater also persuades us that Cleveland discloses the additional subject matter of dependent claims 2, 3, and 11. See Pet. 64–66. Thus, we determine that Clearwater demonstrates that claims 1–3 and 11 are unpatentable as obvious over Nakagawa. F. Ground 3—Obviousness Over Nakagawa and Tanner” slip op. at 17

We were persuaded by Clearwater’s proof that Cleveland’s provisional (Ex. 1006) is “virtually identical” to Cleveland itself (Ex. 1005) and that the provisional provides written description support for at least claim 1 of Cleveland. See Pet. 18–21 (citing Ex. 1006, 2–6, 9). We were also persuaded by Clearwater’s showing that the provisional provides written support for the subject matter relied upon in Cleveland.

    “protectant layers has “a coat weight of from 5 to 30 lbs/3000 ft2.” As noted by Clearwater, Cleveland discloses a total coat weight for layers 14 and 16 as falling within the claimed range. Pet. 32–34 (citing Ex. 1005 ¶ 32). In particular, Cleveland discloses that “the coextruded layer of copolyester (irrespective of which side of the substrate the layer is disposed) is of a total coat weight of between about 10 and about 40 lb/3000 ft2 in any combination of between about 80/20 to 20/80 parts by weight of Ecoflex to Biomax,” of which “a total coat weight of 25 lb/3000 ft2 is preferred.” Ex. 1005 ¶ 32. As disclosed, Cleveland’s total coat weight range of 10–40 lb/3000 ft2 falls almost entirely within the claimed range, and the preferred total coat weight of 25 lb/3000 ft2 falls squarely within the claimed range. Thus, Cleveland satisfies claim elements [1.3.2] and [1.5.2]. See Titanium Metals Corp. v. Banner, 778 F.2d 775, 782 (Fed. Cir. 1985) (“[W]hen, as by a recitation of ranges or otherwise, a claim covers several compositions, the claim is anticipated if one of them is in the prior art.”) (citation omitted).

    “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. Cir. 2001).

    “Patent Owner asserts that, because each of the Flow Limitations relate to water flow through the bowl fill valve, these limitations require adjusting the flow rate of water exiting the flow valve. PO Resp. 15–17 (citing Ex. 2013 ¶ 97); See also PO Sur-Reply 7. 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

This is especially true here, given that the recitations at issue are functional language in an apparatus (system) claim.

Thus, Petitioner’s combination does not require the combination of Gallagher’s and Schofield’s sensors into a single system, and Patent Owner’s “sensor fusion” argument is inapposite. See Tr. 48:8–49:6 (Patent Owner’s counsel confirming that the problem of “sensor fusion” stems from combining disparate sensors in a single system). As noted above, Schofield teaches considering the relative location of the light source in determining whether the light source is from headlights or taillights (that is, an object of interest). See Ex. 1006, 9:26–35. We are persuaded that an ordinarily skilled artisan would be motivated to use this teaching in Gallagher’s device to help distinguish between road markers that are arranged side-by-side and have a reasonable expectation of success in doing so. See Ex. 1005 ¶ 40; Ex. 1003 ¶¶ 77 (“[An ordinarily skilled artisan] would have seen Schofield’s determination of a light source’s location within the field of view as advantageous because it would have allowed Gallagher’s computer to associate the measured reflectance level with the appropriate road marker.”), 79 (“[I]mplementing this determination would have required [an ordinarily skilled artisan] to implement only conventional techniques of image processing (identifying a location of a particular pixel within an array), which was well known by [an ordinarily skilled artisan], to predictably yield the result of the location within a field of view indicating an intensity value associated with a road marker. Given that Schofield and Gallagher disclose similar types of arrays, this combination would have merely required the use of Schofield’s known technique to improve Gallagher’s similar device in the same way.”).” slip op. at 30

    “Patent Owner asserts that the preamble of independent claim 1 reciting “a deodorant stick” is limiting” as it provides antecedent basis for certain other claim elements, specifically, for the recitation of “said stick being free of an aluminum salt” and “said stick” having a particular hardness range. PO Resp. 8–9. We agree. Petitioner does not provide argument to the contrary. See, e.g., Pet. 30 (arguing that Lesniak discloses a deodorant stick in the form of an antiperspirant stick). We determine that no express construction of any other claim term is necessary to resolve the dispute between the parties. Nidec Motor Corp. v.

    “We have considered Patent Owner’s arguments but find, on this record, Petitioner to have the better position. In particular, we are persuaded that a POSA would have been motivated to add magnesium hydroxide to Lesniak’s compositions because Phinney teaches that: (i) zinc oxide has “low activity” as a “deodorant agent”; (ii) magnesium hydroxide is “an effective synergistic effects, hence motivating a POSA to add magnesium hydroxide to Lesniak’s zinc oxide deodorants. Ex. 1004, 1:13- 3:16, 5:61-67. Reply 10; see also PO Resp. 25–26 (arguing that a POSA would have found it obvious to add magnesium hydroxide to the composition of Lesniak because zinc oxide is not a particularly efficacious antimicrobial in deodorants when used alone, whereas magnesium hydroxide is an effective deodorant). We acknowledge that Phinney suggests mixing zinc oxide with water in order to convert zinc oxide to zinc hydroxide. See, e.g., Ex. 1004, 1:17– 19 (“It was also found that a mixture of the hydroxides of zinc and magnesium could provide long lasting protection against odour due to perspiration.”). The evidence of record, however, shows that both magnesium hydroxide and zinc oxide were known options for deodorant antimicrobials, and claim 1 does not require a minimal level of effectiveness such that the combination of magnesium hydroxide and zinc oxide would need to outperform any other combination including the mixture of zinc and magnesium hydroxides. See In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (“Our case law does not require that a particular combination must be the preferred, or the most desirable, combination[.]”). Here, we also credit the testimony of Dr. Michniak-Kohn that “POSA would understand that the water-based vs. anhydrous distinction is not relevant, as a POSA would understand that magnesium hydroxide would still function as an antimicrobial in anhydrous compositions such as those disclosed by Lesniak.” Ex. 1086 ¶ 9 (citing Ex. 1072, 1-2, 5 (disclosing deodorants without added water and with zinc oxide and/or magnesium hydroxide)).

    “teaches baking soda as an effective ingredient in a deodorant. Ex. 1005, 131–33. Baking soda is also known to cause irritation that may motivate some to remove it from deodorants. See Ex. 2011 ¶ 109–110. Thus, the specific set of advantages and disadvantages for using baking soda in a deodorant was known to a person of skill in the art. On this record, the inclusion or exclusion of baking soda presents no unexpected result and the evidence of record establishes that it would have been an obvious matter of design choice within the skill of the art to balance the advantages and disadvantages associated therewith. See Medichem, S. A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine”); see also Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n. 8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another.”) In view of the above, we determine that the preponderance of the evidence supports Petitioner’s argument that claim 8 would have been obvious over the combination of Lesniak, Phinney, Bianchi ’518, and Lamb. Accordingly, we determine that claim 8 is obvious by the combination of Lesniak, Phinney, Bianchi ’518, and Lamb.” slip op. at 32

    “Dr. Papanikolopoulos’s testimony that Kuwata teaches away from modifying its camera 22 to access an external server (such as Fisher’s Internet-enabled external data source) by stressing advantages of a self-contained camera-printer pair without external dependencies. See PO Resp. 15–16, 26–28 (citing Ex. 1005 ¶¶ 75, 77); Ex. 2001 ¶¶ 61–64. The cited disclosures in Kuwata simply do not discuss any advantages arising from a self-contained camera-printer pair without external dependencies, or any disadvantages arising from connecting camera 22 to an Internet server. See Ex. 1005 ¶¶ 75, 77. The cited disclosures instead tout the advantages arising from a camera manufacturer (rather than an end user photographer) specifying the image output control information CI for a specific camera-printer pairing, to reduce differences between an image as confirmed by the end user on the camera’s display and the image outputted by the printer. See id. That advantage, however, has nothing to do with whether camera 22 may or may not communicate with an Internet server. Indeed, rather than being self-contained as Patent Owner and Dr. Papanikolopoulos would have it, we find Kuwata’s camera 22 includes an I/O port for wired or wireless communication to transmit the camera’s image files GF / 10 to various printers 24 and various personal computers (PCs). See Ex. 1005, Fig. 4, ¶¶ 81, 85; Ex. 1003 ¶ 84; Pet. 14. Thus, Kuwata allows for and does not discourage communication between camera 22 and an Internet server such as Fisher’s external data source. In particular, Kuwata does not detract from the benefits of updating image output control information CI after the camera is manufactured, for example so that the camera can be paired with printers that were not yet on the market when the camera was manufactured. Moreover, Fisher recognizes that “a manufacturer may create various ancillary data files 418, and make the ancillary data files 418 available on a distributed computer network like the Internet for subsequent downloading and utilization by camera device 110.” Ex. 1006 ¶¶ 42, 55. That teaching in Fisher dovetails with Kuwata’s disclosure concerning camera manufacturers optimizing their cameras with various different printers, supporting Petitioner’s combination. See Ex. 1003 ¶¶ 84–89, 102–108.” slip op. at 27
