    “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). However, we see no material difference between the level of skill proposed by Patent Owner and that proposed by Petitioner and Dr. Cameron such that our determinations would be the same under either proposed level of skill.” slip op. at 12

    “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

    “Patent Owner argues that the ’105 patent claims were “fully supported as of the filing date of at least the ’606 Application . . .

PO Resp. 63–65; PO Sur-reply 26–29. Patent Owner’s argument is persuasive. The ’606 Application discloses: [W]hen the toilet fill valve 100 is open and water flows from the water inlet 103 to the water outlets 106 and into a toilet tank, an amount of water is also supplied to the bowl fill valve inlet 113 that flows through the bowl fill valve 109 and out the bowl fill valve outlet 116. By virtue of the manual setting of handle 119 of the bowl fill valve 109, the flow of water through the bowl fill valve 109 is regulated. In this manner, the flow of water is regulated so that enough water flows out of the bowl fill valve 109 to fill a toilet bowl without wasting any water down a drain. seen from the passage above, the ’606 Application discloses regulating an amount of water supplied to a toilet bowl using a valve (i.e., a water flow regulator). Ex. 2013 ¶ 288. Further, the ’606 Application states: The bowl fill valve 109 may be, for example, a ball valve, a gate valve, a globe valve, a plug valve, a diaphragm valve, a butterfly valve, a needle valve, a sliding gate, a quick turn valve, a knife valve or any other appropriate type of valve as can be appreciated by those with ordinary skill in the art.” slip op. at 42

Petitioner argues that implementing Lumia’s teaching of determining the luminance of traffic signs in Gallagher’s system would allow Gallagher’s system to calculate the retroreflectivity of road markers as a means of identifying any markers that do not meet minimum acceptable reflectance levels for countries that require a minimum retroreflectivity level for road markers. Pet. 46 (citing Ex. 1003 ¶ 116; Ex. 1005 ¶¶ 49, 77; Ex. 1019, 6, 8–11).7 However, Gallagher already discloses determining whether the 7 Petitioner and Dr. Thorpe cite to the original pagination of Exhibit 1019 rather than the added exhibit pagination. reflectance level of each road marker meets a predetermined minimum acceptable reflectance level and tagging those road markers that do not meet the minimum acceptable reflectance level to identify them for replacement.

Indeed, both Petitioner and Dr. Thorpe describe Gallagher’s system as ensuring that road markers meet minimum retroreflectivity standards: “Gallagher’s apparatus tests ‘road markings and road markers such as, for example, road signs and posts, reflective painted lines whether continuous or broken, and . . . raised pavement markers’ ‘to ensure they continue to meet minimum standards of reflectivity/retroreflectivity.’” Pet. 9 (alteration in original) (emphasis added) (citing Ex. 1005 ¶¶ 3, 6, 31–33); Ex. 1003 ¶ 55 (alteration in original) (emphasis added) (citing Ex. 1005 ¶¶ 3, 6, 31–33).

During his deposition , Dr. Thorpe confirmed that this obviousness theory relies only on Lumia’s equations. See Ex. 2025, 60:5–65:2. This is an improper new argument. See, e.g., Henny Penny Corp. v. Frymaster LLC, 938 F.3d 1324, 1330–31 (Fed. Cir. 2019) (“[A]n IPR petitioner may not raise in reply ‘an entirely new rationale’ for why a claim would have been obvious.”). Notably, this new obviousness theory appears to stem from Patent Owner’s witness, Dr. Papanikolopoulos, noting differences in Gallagher’s and Lumia’s disclosures. See Pet. Reply 21 (citing Ex. 2023 ¶¶ 71 n.2, 89). Even considering Petitioner’s new theory, we find it unpersuasive because Petitioner does not explain adequately how the “determining a luminance value” recitation is met. Per Petitioner, Gallagher measures the coefficient of luminous intensity, but Petitioner does not identify a “luminance value” as recited in claim 15. Dr. Papanikolopoulos testifies that the coefficient of luminous intensity is not a luminance value: “As is well established, coefficient of luminous intensity—which is what Gallagher calculates—is a measurement of retroreflectivity (usually expressed in units of candelas, or millicandelas, per lux per square meter, i.e., cd/lx/m2), not luminance (usually expressed in candelas per square meter, i.e., cd/m2).

    “We agree with Patent Owner that Petitioner has not articulated persuasive reasoning for combining the teachings of Gallagher and Lumia. Petitioner argues that implementing Lumia’s teaching of determining the luminance of traffic signs in Gallagher’s system would allow Gallagher’s system to calculate the retroreflectivity of road markers as a means of identifying any markers that do not meet minimum acceptable reflectance levels for countries that require a minimum retroreflectivity level for road markers. Pet. 46 (citing Ex. 1003 ¶ 116; Ex. 1005 ¶¶ 49, 77; Ex. 1019, 6, 8–11).7 However, Gallagher already discloses determining whether the 7 Petitioner and Dr. Thorpe cite to the original pagination of Exhibit 1019 rather than the added exhibit pagination. reflectance level of each road marker meets a predetermined minimum acceptable reflectance level and tagging those road markers that do not meet the minimum acceptable reflectance level to identify them for replacement.

Indeed, both Petitioner and Dr. Thorpe describe Gallagher’s system as ensuring that road markers meet minimum retroreflectivity standards: “Gallagher’s apparatus tests ‘road markings and road markers such as, for example, road signs and posts, reflective painted lines whether continuous or broken, and . . . raised pavement markers’ ‘to ensure they continue to meet minimum standards of reflectivity/retroreflectivity.’” Pet. 9 (alteration in original) (emphasis added) (citing Ex. 1005 ¶¶ 3, 6, 31–33); Ex. 1003 ¶ 55 (alteration in original) (emphasis added) (citing Ex. 1005 ¶¶ 3, 6, 31–33).

The disclosure need only reasonably convey to a POSA that the inventor had possession of the subject matter in question, even if every nuance of the claims is not explicitly described in the specification. Id.; see Ariad, 598 F.3d at 1351. Patent Owner argues that the ’993 patent claims were “fully supported as of the filing date of at least the ’606 Application . . .

PO Resp. 68; PO Sur-reply 28–30. Patent Owner’s argument is persuasive. The ’606 Application discloses: [W]hen the toilet fill valve 100 is open and water flows from the water inlet 103 to the water outlets 106 and into a toilet tank, an amount of water is also supplied to the bowl fill valve inlet 113 that flows through the bowl fill valve 109 and out the bowl fill valve outlet 116. By virtue of the manual setting of handle 119 valve 109 is regulated. In this manner, the flow of water is regulated so that enough water flows out of the bowl fill valve 109 to fill a toilet bowl without wasting any water down a drain. Ex. 1012, 47, ¶ 8 (emphasis added); see also Ex. 1001, 2:28–39.

Analysis of Claims 1–18 Schuster is available as prior art if the ’993 patent is only entitled to its January 27, 2014, filing date and not entitled to claim priority to earlier filing dates of the parent applications. On its face, the ’993 patent claims priority to a number of earlier parent applications, including Application No. 12/786,904 (the ’904 Application) filed May 25, 2010, and the Application code 63. Petitioner contends that the ’993 patent is not entitled to claim priority to the filing date of the earlier parent applications, and, thus, Schuster, a parent application of the ’993 patent, is available as prior art.15 Pet. 91–92. Petitioner alleges that the earlier parent applications, specifically Application No. 12/786,904 (the ’904 Application), do not provide written description support for the ’993 patent’s claim term “water flow regulator.” According to Petitioner, “water flow regulator” encompasses both adjustable devices for restricting the flow of water (i.e., valves) and fixed devices for restricting the flow of water (i.e., restrictors). Pet. 15. Petitioner contends that the ’904 Application does not provide support for water flow restrictors and, thus, does not provide support for the broader claim term water flow regulators. Id. at 14–15, 91–92. Petitioner argues that only adjustable water flow devices (i.e., valves) are supported by the ’904 Application. Id. Petitioner, thus, asserts that earliest effective filing date of the ’993 patent’s claims is the filing date of its application, January 27, 2014. Id. at 92.

    “without first determining how much fat existed to begin with, i.e., prior to the side of meat being trimmed. But, as Provisur correctly notes, Weber ignores what one skilled in the art reasonably would have understood from reading Young’s disclosure as a whole. See Pet. 30–36 (citing Ex. 1003 ¶¶ 104–106, 109–112); Pet. Reply 2–12. When that is done, one skilled in the art would have understood that a necessary premise of Young’s determination of the thickness of fat to remain on the loin is knowing the thickness of the fat to begin with, which Young’s imaging system 190 and imaging processing routine 240 determine by first analyzing a series of “fat/lean separation lines” and “edge lines” in the side of meat being trimmed. Pet. 30–32 (citing Ex. 1004, 17:34–62, 18:33–56, 22:53–24:38, Figs. 2, 13); Pet. Reply 3–7 (citing portions of same evidence). More specifically, as described in Young (and articulated by Provisur), the side of meat is placed fat side down on a product support, i.e., platen 20. See Ex. 1004, 7:16–21, Figs. 1, 2. Using several cameras—top plan camera 196, end view camera 197, and fat line camera 198—Young’s imaging system 190 acquires multiple images of the side of meat from various angles and under various lighting conditions to “provide image data regarding each side of [meat].” See id. at 17:34–18:56. That image data is then used by Young’s image processing routine 240 to generate a series of demarcation lines on the side of meat, including: (1) fat/lean separation lines (representing the interface between the loin meat and the fat layer along top, side, and end views of the meat product; and (2) edge lines (representing lines along the outer surface of the meat product). See id. at 22:53–23:67, Figs. 10, 13 (Blocks 242, 246, 250, 254). In addition, “a plurality of points (preferably 20) are generated for each of the fat/lean separation and edge lines using known pattern matching routines.” Id. at 23:28–30, Fig. 13 (Blocks 244, 248, 252, 256); see also id. at 23:61–63 (essentially same). The fat/lean separation and edge lines (and points therein) generated by Young’s image processing routine 240 are then used to calculate certain dimensions and characteristics of the side of meat, such as height, length, and width. Id. at 24:10–22, Fig. 13 (Block 258). As Provisur’s expert credibly testifies, one skilled in the art would have understood that the dimension from the fat/lean separation line to the edge line along the outer surface represents the thickness of fat cover on the side of meat, i.e., before the fat is trimmed. See Ex. 1003 ¶ 106. Insofar as how that dimension is used, Young states that controller 172 uses “dynamic (real time) image data” of the fat/lean separation and edge lines “to dynamically modify the cutting profile of the loin knife assembly 100 so that the assembly follows a fixed distance from the separation line to provide the optimum fat cover for the loin.” Ex. 1004, 18:32–45; see also id. at 17:48–52 (describing “real time processor” for “image processing routines”). Notably, according to Young, the “fixed distance” represents the “desired” thickness of fat that remains on the loin, after trimming, and “sufficiently keeps the loin from drying out, but doesn’t make the loin look too fat,” although “[o]ther fat thicknesses may be desired in the alternative.” Id. at 20:60–66; see also id. at 10:39–42 (“Through control of the knife blade along several axes, assembly 100 preferably produces an optimum separation between loin and belly, with a desired fat covering left on the loin.” (emphases added)).

  • Strike new argumentNew argument consideredDecided for patent owner

    “argument that Weber considers vital to its dispute of Provisur’s showing for the claimed fat thickness determination. During oral hearing, Weber repeatedly argued that Provisur changed theories midstream, i.e., between the time of the petition and the hearing. See Hrg. Tr. 22:18–24:47; see also id. at 31:14–22, 33:8–18, 34:16–20, 49:17–50:15, 54:16–56:25 (repeating same argument). More specifically, according to Weber, Provisur originally relied only on image data from Young’s “top view” camera as processed in “block 246” of Young’s image processing routine 240 when showing how Young meets the claimed fat thickness determination, whereas now Provisur relies on image data from Young’s “end view” cameras as processed in “Block 254.” Compare PO Sur-Reply 3–6 (focusing on Young’s “top view camera” in “block 246”), with Hrg. Tr. 27:4–16 (“[Block] 246, which is what they relied on, is processing images from the top-view camera in Young’s system. It is generating lines from the top-view camera in Young’s system. What they are newly trying to rely on today, for the first time, is Block 254 that is discussed toward the bottom of column 23 in Young, and that analyzes different images from a different camera. It is the end camera. It generates different lines. It demonstrates an end fat/lean line and an end edge line. Prior to today’s hearing, neither Petitioner, nor its expert, had ever discussed Block 254. You will not find a single reference to 254 in their papers, nor have they discussed the end edge line. It is completely new today. It finds absolutely no support in the record.” (emphases added)). We disagree with Weber’s contention. As shown and described in the petition, Provisur relies on more than simply Young’s “top view” camera and “block 246.” See Pet. 29–31. Rather, in its petition, Provisur annotates Young’s Figure 2 to show that image data from all three cameras of “imaging system 190”—“top plan camera 196, end view camera 197, [and] fat line camera 198”—play a role in the determination of fat thickness.8 Id. at 30. Moreover, Provisur cites the entire process depicted in “Figure 13” and described in columns “22:53–24:38” of Young as critical to the determination. Id. at 31. Those cited portions of Young involve not only the analysis of fat/lean and edge lines from “top view” images (block 246), but also the analysis of fat/lean and edge lines from “end view” images (blocks 250 and 254). See Ex. 1004, 23:12–24:13. In other words, Provisur’s showing for the claimed fat thickness determination is based on Young’s collective analysis of all those images. Indeed, Provisur’s expert confirms as much when confronted by Weber on cross-examination— Q. How does [Young] use the other cameras to identify that fat/lean separation line? A. Again, this is a -- this is a three-dimensional product that’s not regular, and all the views basically are needed to be able to describe that complex three-dimensional shape, so that the knife will be able to cut at that -- at that line, offset by whatever desired thickness there is, on that three-dimensional shape. Ex. 2006, 25:15–27:19 (emphasis added). 8 Indeed, contrary to Weber’s assertion, Provisur highlights “fat lean separation camera 198,” not top view camera 196, as most critical to the determination of fat thickness. Pet. 31. In the end, we reject the notion that Provisur changed theories” slip op. at 12

In my opinion, a POSITA would understand that, without acquiring this second identifier in the sequence (which 14 Prior art patents enjoy a presumption of enablement. Apple Inc. v. Corephotonics, Ltd., 861 Fed. Appx. 443, 450 (Fed. Cir. 2021). Wu is presumed to enable what it discloses. See Amgen Inc. v. Hoechst Marion Roussel, Inc., 314 F.3d 1313, 1355 (Fed. Cir. 2003) (“a presumption arises that both the claimed and unclaimed disclosures in a prior art patent are enabled”). However, even without applying this presumption, Wu provides a disclosure that establishes how to create the relationship between the label identifying information and the label location information of the added shelf label by extrapolation or interpolation without the reading device acquiring the label identifying information of the adjacent shelf label which is already installed. See Ex. 1003, 3:59–4:28. is explicitly shown in FIG. 3B of Wu), the reading device could not possibly “create[] the relationship between the label identifying information and the label location information[,]” by extrapolating from the ESL that is already installed as required by steps S104 and S106. Ex. 1003, [4:26-28]. Ex. 1009 ¶ 81. Dr. Tentzeris does not support his opinion with any explanation, reasoning, facts or data, here or elsewhere. This unsupported, conclusory testimony is entitled to little or no weight. See cxLoyalty, Inc. v. Maritz Holdings Inc., 986 F.3d 1367, 1378 (Fed. Cir. 2021) (“We do not accord weight to conclusory expert testimony.”); see also 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). There is no evidence that supports Petitioner’s assertion that a skilled artisan would understand from Wu that the reading device acquires the label identifying information of a second shelf label that is already installed and adjacent to the added shelf label.” slip op. at 27

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “A person having ordinary skill in the art relating to the subject matter of the ’709 Patent as of the Critical Date (“POSITA”) would have had at least a Master of Science Degree in an academic area emphasizing electrical engineering, computer engineering, wireless telecommunication systems, or an equivalent field (or a similar technical Master’s degree, or higher degree). Pet. 6 (citing Ex. 1009 ¶ 31). Petitioner further contends, in the alternative, that “a POSITA would have had a Bachelor’s Degree (or higher degree)” in one of the fields noted above, with “two or more cannot demonstrate unpatentability of any claim of the ’709 Patent because Petitioners fail to identify a ‘reading device’ that acquires and transmits the ‘sequence of label identifiers’ recited by the claims.”). Our decision is based on our determination that Petitioner has failed to establish that the cited art teaches or suggests acquiring and transmitting a sequence of label identifiers as recited in the independent claims of the ’709 patent. years of work experience” in one of those fields. Id. According to Petitioner, “[a]dditional education in a relevant field or relevant industry experience may compensate for a deficit in one of the other aspects of the requirements stated above.” Id. Patent Owner applies Petitioner’s definition of the level of ordinary skill in the art. PO Resp. 16. Determining the level of ordinary skill in the art involves various factors, including the “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 Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). The prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). We adopt the assessment offered by Petitioner, as it is not disputed by the Patent Owner and is consistent with the ’709 patent and the asserted prior art.” slip op. at 10

    “necessary to resolve the controversy involved in this IPR, and the terms of the ’709 Patent should be given their ordinary and customary meaning.” Pet. 4. In the claim construction section of its Response, Patent Owner discusses the claim terms “location(s)” and “planogram.” See PO Resp. 16– 29. As discussed in our analysis below, we determine that Petitioner has failed to show that the prior art teaches or suggests certain limitations of the claims that do not include either the term “location(s)” or “planogram.” Accordingly, no need exists to expressly construe any claim terms to resolve the parties’ disputes. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Our decision relies on the plain and ordinary meaning of the limitations on which our decision is based and no need exists to expressly construe any claim term to make our decision.8” slip op. at 9
