      “Patent Owner argues that the ’105 patent claims were “fully supported as of the filing date of at least the ’606 Application . . . March 11, 2004” because the ’606 Application discloses regulating water flow and a POSITA would know that appropriate devices for regulating water flow includes nonadjustable waterflow restrictors. 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

Making insertion and removal of the string easier and quicker provides a notable advantage over Wagner’s existing device. See id. Scorch itself supports this argument and the related expert testimony because it discusses insertion and removal of strings and stated that the slot allows a user to “swap them out really quick.” Ex. 1007, 3:30–53. Petitioner also persuasively argues that a POSITA would know how to add the slot while maintaining the proper operation of the device, such as allowing insertion and removal of the string and avoiding inadvertent exiting of the string from the device. See Pet. 86–87 (citing Ex. 1002 ¶¶ 175–176; Ex. 1007, 4:00–30, Ex. 1008, 2:49–52); Pet. Reply 19, 21 (citing Ex. 1002 ¶¶ 174–176). We find Petitioner’s arguments and reasoning in support of adding Scorch’s slot to Wagner’s housing straightforward and persuasive. Patent Owner’s arguments against the combination do not directly refute Petitioner’s reasoning or cast doubt on Scorch’s statement that its slot enables “quick” insertion and removal of a string—quicker than Wagner’s method that requires removal and replacement of a cover on its housing. See PO Resp. 16–22; PO Sur-reply 14–20; Ex. 2002 ¶ 187 (acknowledging inconvenience of Wagner’s existing process for insertion and removal of a string). Patent Owner suggests that Petitioner’s proposed combination fails to take into consideration certain drawbacks such as the risk of inadvertent string exit from the housing or slot, but Petitioner expressly addresses such concerns in the Petition. See PO Resp. 18 (stating that Scorch’s slotted funnel may allow the string to “shoot out the slot” and that Scorch addresses this by adding “a bent wire” to “prevent the string from coming out the side”); PO Sur-reply 16–17; Pet. 86–87 (arguing that Wagner’s flanges would help to trap the string in place, but if not, Scorch’s additional structures could be used to restring the string and “to further reduce the risk of a string inadvertently exiting” the device). We agree with Petitioner that a POSITA would understand how to incorporate Scorch’s slot without causing inadvertent removal of the string—using structures already present in Wagner and Scorch—and the need to add such unclaimed structurers does not teach away from the combination as Patent Owner suggests.

See Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed.

In addition, even if Patent Owner were correct that Wagner’s existing design works as well as Petitioner’s proposed combination, given all of the tradeoffs involved, that would not fatally undermine Petitioner’s showing. In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (obviousness does not require that the proposed combination “is the preferred, or most desirable, combination”). On this record, Petitioner’s (and Scorch’s) stated advantages that are achieved when adding Scorch’s slot to Wagner’s housing adequately support Petitioner’s motivation to combine rationale.” slip op. at 26

      “Petitioner describes a person of ordinary skill in the art (“POSITA” or “ordinarily skilled artisan”) at the time of the invention as having “a Bachelors’ degree in electrical engineering or a comparable field of study, plus approximately two to three years of professional experience with electronic and optoelectronic device design” and notes that “[a]dditional graduate education could substitute for professional experience, and significant experience in the field could substitute for formal education.” Pet. 5–6 (citing Ex. 1002, Neikirk Decl., ¶ 23). Patent Owner’s expert, Dr. Bretschneider testifies that In my opinion, the field of “electronic and optoelectronic device design” is too broad. A POSITA of the ’121, had at least a Bachelors’ degree in a field of engineering or physics and at least two to three years of professional experience related to the design and manufacture of the relevant aspects of flat panel displays. Additional relevant graduate education related [sic] could reduce but not eliminate the time requirement for professional experience. While Dr. Neikirk proposes a different definition of a POSITA, the differences do not have material effect on my opinions rendered below. Regardless of which definition of a POSITA were used, my conclusions would remain the same Ex. 2005, Bretschneider Decl., ¶ 39. We agree with and will apply Petitioner’s statement of the level of ordinary skill in the art. This level of ordinary skill is reflective of the education and experience that would have been required to understand the problems and solutions identified in the ’121 patent and the prior art.

      “We find these definitions to be of some help in construing this term. We find that the common thread is that a “passivation layer” is an insulating layer that provides protection from the environment to the layers below it. See Ex. 1012, 140; Ex. 1013, 542, Ex. 1014, 798; Ex. 2010, 3; Ex. 2013, 1. We find this construction to be most consistent with the broad claim language and the disclosure in the Specification. Although “tying up dangling bonds,” may be a mechanism by which some materials provide such protection, nothing in the Specification or the extrinsic evidence provided appears to require that. Also, while chemical protection may be one kind of protection none of the evidence suggests that is the only protection that is provided. Moreover, nothing in the Specification supports reading a chemical protection requirement into the construction. Thus, we decline to adopt that portion of Patent Owner’s construction. Instead, we construe passivation layer as “an insulating layer that provides protection from the environment to the layers below it.” We need not construe the term any further to resolve the parties’ dispute over this claim language.

      “constructions for “passivation layer” and “capping layer.” We find that Petitioner has presented sufficient evidence to show that Anzai discloses both a “passivation layer” and a “capping layer.” As we explained above, we have construed “passivation layer” to mean “an insulating layer that provides protection from the environment to the layers below it.” Petitioner has shown that “first planarization film 17” is an insulating layer. See Ex. 1002 ¶¶ 62–65. We further find that Petitioner has shown sufficiently that “first planarization film 17” is “formed over the entire surface for flattening, which will protect the semiconductor surface from the surrounding environment.” Id. ¶ 63. We have rejected Patent Owner’s contentions that the film must tie up “dangling bonds,” and instead determined that protecting the surface from the environment is sufficient. Thus, we find that Petitioner has shown by a preponderance of the evidence that Anzai discloses the “passivation layer” of claim 3. As we explained above, we have construed “capping layer” to be “an insulation layer covering (i.e., capping) an underlying layer or structure.” Here, Petitioner has shown that Anzai’s planarization film 19 meets the claimed “capping layer.” See Pet. 20. We find that Petitioner has shown that it is more likely than not that “planarization film 19” is made of insulating material. As Dr. Neikirk persuasively testifies, Anzai discloses that planarization layer 17 may be made of an organic resin for flattening the surface. EX1003, 4:20-24. While Anzai does not disclose the material for planarization layer 19, it must be made of an insulation material because in the embodiment of Fig. 3A, it is the sole layer between electrode layer 71 and cathode layer 65 forming the second capacitor. Id., 6:3–8; Fig. 3A. Moreover, Anzai discloses that the first planarization film 17 and the second planarization film 19 for the first embodiment “function as the capacitance insulating film for this configuration.” Id., 5:62–67. Ex. 1002, Neikirk Decl., ¶ 62. We find this testimony well-reasoned and entitled to substantial weight. We further agree with Dr. Neikirk that a “POSITA would further understand that the second planarization film 19 is then further disposed on the first planarization film 17 (capping the passivation layer).” Id. ¶ 63 (citing Ex. 1003, 5:3–13; Figs. 2A–B, 3A–B).

      “motivation to combine Anzai and Yamazaki. See Pet. 25–27; Ex. 1002, Neikirk Decl., ¶¶ 78–79. First, Patent Owner argues that essentially silicon nitride is an inferior material to use for Anzai’s planarization layer 17 compared with organic resin. PO Resp. 13–15. However, “[i]t’s not necessary to show that a combination is the best option, only that it be a suitable option.” Intel Corp. v. Qualcomm Inc., 21 F.4th 797, 800 (Fed. Cir. 2021) (emphasis in original). Patent Owner does not argue that silicon nitride would not work, but rather that it would be more difficult and more expensive to use. See PO Resp. 14. But “the fact that the two disclosed apparatus[es] would not be combined by businessmen for economic reasons is not the same as saying that it could not be done because skilled persons in the art felt that there was some technological incompatibility that prevented their combination. Only the latter is telling on the issue of nonobviousness.” Grit Energy Solutions LLC v. Oren Techs., LLC, 957 F.3d 1309, 1323 (Fed. Cir. 2020) (quoting Orthopedic Equip. Co., Inc. v. United States, 702 F.2d 1005, 1013 (Fed. Cir. 1983)). “Likewise, a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.” Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). Here, Petitioner explains that “a POSITA would have known that organic materials usually have lower dielectric constants than inorganic materials, such as SiN, and a higher dielectric constant is desirable for the insulator in a capacitor since that leads to higher capacitance per unit area.” Pet. 26 (citing Ex. 1002, Neikirk Decl., ¶ 78). Petitioner further explains that this “then allows a reduced area storage capacitance element, one of the objectives of Anzai.” Id. (citing Ex. 1003, code (57)). Patent Owner’s focus mainly on planarization (PO Sur-reply 16–17) ignores that the Anzai’s planarization layers 17 and 19 also “function as the capacitance insulating film.” Ex. 1003, 5:65–67. Thus, although there are tradeoffs, Petitioner has shown sufficiently that a POSITA would have been motivated to incorporate the teachings of Yamazaki regarding potential materials for planarization layers 17 and 19. Second, Patent Owner argues that a Petitioner has failed to provide an adequate reason to select silicon nitride from Yamazaki’s list of potential materials. We disagree. Petitioner has explained the benefits of selecting a high dielectric inorganic material. Pet. 26. Yamazaki provides only three potential options—silicon oxide, silicon nitride, and silicon oxynitride. See Ex. 1004, 11:45–50. Moreover, Dr. Neikirk testified, supported by multiple references, that using silicon nitride was well known in the prior art at the time of the invention. See Ex. 1002, Neikirk Decl., ¶ 75 (citing Ex. 1007; Ex. 1008; Ex. 1009). “When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp.” KSR, 550 U.S. at 421. Indeed, “[i]f a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability.” Id. at 417. This is the case here. Petitioner has shown that a person of ordinary skill seeking to improve the capacitance of Anzai’s planarization layers 17 and 19, without increasing the size of the capacitor, would have looked at the inorganic materials identified in Yamazaki as suitable for the purpose, and it would have been would obvious to choose silicon nitride, a well-known, and predictable material for the application. Thus, we disagree with Patent Owner that Petitioner has failed to show a sufficient reason for selecting silicon nitride from Yamazaki’s list of suitable materials. Third, Patent Owner argues that Petitioner’s contentions only support” slip op. at 37

Reply 17–18 (citing Ex 1003 ¶ 157; Ex. 1020 ¶ 45). Further, contrary to Patent Owner’s contention that POSITA would not have combined Weaver with Lee ’053, Song, Lee ’149, or Bae without the use of hindsight (PO Resp. 33–45), as Petitioner points out, Lee ’149, for example, “explicitly teaches that ‘the electrode pattern 45 serves to lower the resistance of the first electrode 41.” Pet. Reply 58 (citing Ex. 1011 ¶ 38). Similarly, Bae “explicitly teaches that the “auxiliary electrodes 139 contact the first electrode 132 to commonly apply a voltage to the sub-pixels” and “reduces the resistance of the first electrode.” Id. at 66 (citing Ex. 1012 ¶¶ 37, 59). As such, Petitioner’s proposed combinations are supported by at least by Lee ’149’s and Bae’s teachings of applying a second electrode to lower the resistance and voltage drop between anode 406 and the VDD line of Weaver. See, e.g., Ex. 1011 ¶ 38; Ex. 1012 ¶¶ 37, 59. We are persuaded by Dr. Baker’s testimony that a POSITA would have understood that higher resistance between the power or ground line to the light emitting device would consume more power and require higher operating voltages, and thus, would have been motivated to implement the solutions of Lee ’053, Song, Lee ’149, or Bae to lower the resistance between anode 406 and voltage source VDD in Weaver. Ex. 1003 ¶¶ 145, 158, 184, 203. We agree with Petitioner, supported by Dr. Baker’s testimony, that a POSITA would have had a reasonable expectation of success the combining the references as suggested, wherein such modification “involves modifications of only routine skill in the art,” which “involve known method,” and “would have yielded predictable results. Pet. 42, 48–49, 59, 67–68; Ex. 1003 ¶¶ 145, 158, 184, 203.

Based on the complete record presented, we determine Petitioner has shown by a preponderance of the evidence that claims 6–8 would have been obvious over the combination of Weaver and Lee ’053 or alternatively over the combination of Weaver and Song, and that claims 10 and 11 would have been obvious over the combination of Weaver and Lee ’149 or alternatively over the combination of Weaver and Bae.” slip op. at 33

Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed.

Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997). Written description is a question of fact judged as of the relevant filing date. Falko–Gunter Falkner v. Inglis, 448 F.3d 1357, 1363 (Fed.

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 . . . March 11, 2004” because the ’606 Application discloses regulating water flow and a POSITA would know that appropriate devices for regulating water flow includes nonadjustable waterflow restrictors. 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.

We agree with Patent Owner that a plain reading of the wherein clause requires the treating to begin at the introitus and extend at least the first centimeter into the vagina and up to 3.5 cm in from the introitus. This construction is consistent with the ’511 patent’s Specification, which states: In typical embodiments, the length of the energy delivery element is about 1 to about 3 cm in length, in other embodiments it may be as long as about 4 cm. This is a length well adapted to treating the lower aspects of the vagina, wherein treatment by the method comprises contacting the vaginal epithelium in a region that extends from the introitus inward to a position about 3 to 4 cm inward from the introitus. In some embodiments of the invention, the method can b[e] practiced with a single row of parallel contract sites immediately inside the introitus. In other embodiments, the method may include deeper rows, or rows that overlap an initial row, while keeping the contact sites within the lower portion of the vagina.

Given the plain language of claim 1, consistent with the ’511 patent’s Specification, we construe “heating a portion of the vagina extending from the introitus inwardly to a location from 1 cm to 3.5 cm in from the introitus” to require heating a portion of the vagina beginning at the introitus and extending at least the first centimeter into the vagina and up to 3.5 cm in from the introitus.” slip op. at 12

      “Although we agree with Petitioner that the plain meaning of limitation 1.2 does not require the recited determination to occur at the first well, it does require the determination to be about the condition(s) of the fluid communicated to the first well by the manifold, regardless of where or how the information is gathered to make that determination. Limitation 1.2 recites plainly that the “determining” step is specifically about whether “the fluid communicated via the manifold has satisfied one or more conditions.” Ex. 1001, 22:38–39 (emphasis added). Considering the antecedents for “the fluid” and “the manifold”––i.e., “communicating fluid to a first well via a manifold” (id. at 22:35, limitation 1.1)––limitation 1.2 expressly identifies the fluid which “the manifold” has “communicated” to the first well to be exactly the fluid used for “determining” whether “one or more conditions” are “satisfied” to trigger the recited responses. Id. This is because “the fluid” refers to a fluid passing to a first well by way of a manifold and the past tense of “communicated via the manifold” indicates, more specifically, that it is the fluid passed by the manifold which must satisfy a condition(s). The Specification of ’770 patent illustrates this by checking the “frac rate” of the fluid discharged by a manifold to a first well to make the determination about whether to permit a regular swap or a continuous pumping swap (“CP swap”). Ex. 1001, 13:30–54, Fig. 12. Therefore, contrary to Petitioner’s representation that limitation 1.2 does not “requir[e] the fluid used for ‘determining’ to have been communicated to the first well” (Pet.

      “We determine that the Petition did not adequately present Petitioner’s contention that Tolman discloses or suggests a “master valve” that a skilled artisan would understand to be the claimed “first valve,” which is first introduced in the Reply. The issue is whether Petitioner’s identification of Tolman’s “tree valve” for the claimed first valve was particular enough to allow Petitioner to rely specifically on the “master valve” in the well tree to show Tolman discloses the first valve. We find that it is not. It is undisputed that a well tree include several different valves: (1) valves for communicating fluid to a well (e.g., for treatment or stimulation); (2) valves for communicating fluid from a well (e.g., for flowback); and (3) valves for communicating fluid both to and from a well (e.g., master valve). See Reply 19–20; Ex. 1002 ¶¶ 542–545; Ex. 1044 ¶¶ 33–34, 38–42; Tr. 33:12–18, 34:3–12, 36:8–37:18, 39:4–17; Ex. 2013, 85:4–86:19, 87:1–12, 89:2–11. And the opening/closing of these different valves are controlled independently of the other valves based on different parameters. Id. identifying a tree valve, generally, does not provide the particularity necessary to provide notice that the master valve is the particular valve being relied upon. Further compounding this problem is the fact that the Petition repeatedly refers to a plurality of valves, rather than a singular “master valve.” The variability of possible valves suggested by simply referring to a tree valve fails to provide a level of particularity that clearly identifies which specific structure is being relied upon to perform which part of the recited procedure. Ultimately, we agree with Patent Owner that because the Petition does not specifically identify the master valve in the Petition, which the Petitioner’s Reply suggest was the intention all along, Patent Owner was put at a disadvantage because its ability to fully develop a response was impeded. Therefore, Petitioner’s reliance particularly on the “master valve” of the well tree, and the newly introduced evidence associated therewith, was improper and may not be considered. Nevertheless, as discussed below, even if Petitioner were allowed to rely on the master valve, we still find the Tolman Grounds to be deficient.” slip op. at 56

At the time of the invention, when a first well is being operated individually using high pressure pumping, we find that skilled artisans would have considered concurrent operation of the second well’s valves to be hazardous and activities that can not occur. See Ex. 1031, 4 (“specifically identified activities that were restricted from occurring at the same time (i.e., CAN NOT OCCUR activities). As an example, if the operations on a well involved high pressure pumping . . . then manipulating manifold well valves and wellhead trees valves on another well were not allowed to be performed concurrently”); Ex. 2012 ¶ 148. would have had a reasonable expectation of being able to successfully avoid the unacceptable hazards known to be associated with opening second valve 472 and communicating fluid to second well 142, while individually operating on first well 140 using high pressure pumping.10 Furthermore, Petitioner provides no persuasive evidence that a skilled artisan would have known that those unacceptable hazards could be avoided (or acceptably minimized) by using a condition(s) of the fluid communicated by first isolated manifold path 122 to first well 140 as a trigger for opening second valve 472 and communicating fluid to second well 142, while first well 140 is being individually operated.” slip op. at 34

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

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) appliesDecided for patent owner

      “We determine that the evidence of record overcomes the presumption that § 112, para. 6 does not apply because “thrust-bearing element” does not recite sufficiently definite structure in this case. See, e.g., Pet. 22 (the term is not used here according to its common meaning). First, the word “element” is a “[g]eneric term[]” or “verbal construct[]” often “used in a claim in a manner that is tantamount to using the word ‘means’” because it does not “connote sufficiently definite structure.” Williamson, 792 F.3d at 1350. We find nothing in the ’121 patent or elsewhere in the record suggesting that “element” in the term “thrust-bearing element” should be considered other than a generic placeholder term. Second, although the term “thrust bearing” may connote certain structure, “thrust-bearing element” does not. A “thrust bearing” is “a well-known term of art in engineering and is ‘a bearing which sustains axial loads and prevents axial movement of a loaded shaft.’” Ex. 1003 ¶ 46 (citing Ex. 1017, 2147). “The balls of traditional thrust bearings are positioned inline with the axial force, as thrust bearings are designed specifically to transmit axial load.” Id. Here, however, “thrust-bearing” is hyphenated, and is therefore a phrasal adjective modifying “element” rather than the noun phrase “thrust bearing.”8 Further, there are “substantial differences”” slip op. at 15

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Term construed board ownDecided for patent owner

      “We largely agree with Petitioner. “[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.” B. Braun Med. Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed.Cir.1997). The Specification of the ’121 patent “clearly links or associates” two components with the function of bearing axial thrust from the sowing disc: shaft 27 with flanging 30, and thrust-bearing plate 31. Ex. 1001, 3:25–35. Thrust-bearing plate 31 is expressly described as “bear[ing] on that surface of the disc which faces seal 24 . . . in order to withstand at least some of the axial load produced by the disc 16 on the seal 24. Ex. 1001, 3:28–31. Rotatably-mounted shaft 27 with flanging 30 is “fixed” to thrust-bearing plate 31 and therefore bears the axial load from the disc via the thrust-bearing plate. Id. at 3:25–28.10 10 Drive element 32 is described as part of thrust-bearing element 26 and permits thrust-bearing element 26 to be driven in rotation with sowing disc 16. Ex. 1001, 3:36–40. It is not described as bearing any axial load, however. Further, it is not necessary for the thrust-bearing element to rotate with the sowing disc for that element to bear axial load from the sowing disc. See id. at 3:58–59 (“Provision is also made for the thrust-bearing element 26 to be made idle and not driven in rotation by the [drive] shaft 20.”). Ultimately, however, whether drive element 32 is properly considered as part of the corresponding structure is not relevant to the outcome of this case. We disagree with Patent Owner that bearings 28 and seat 29 should be considered corresponding structure. The Specification does not associate these structures with any axial load-bearing function. Instead, bearings 28 and seat 29 are described as the means by which, and the location in which, shaft 27 is rotatably mounted. Ex. 1001, 3:25–27. Regardless, whether or not bearings 28 and seat 29 are considered corresponding structure does not affect the outcome of this case. In summary, we construe “thrust-bearing element” as a means-plus- function claim term under 35 U.S.C. § 112, para. 6. Its recited function is to bear thrust, or more specifically to “withstand at least some of the axial load produced by the disc on the seal.” The structure described in the Specification as corresponding to this function is shaft 27 with flanging 30, and thrust-bearing plate 31. We construe the limitation as directed to this structure, and equivalent structures.” slip op. at 21

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “The question is not whether the patentee disclaimed coverage over structures in which the thrust-bearing element is not located entirely in the movable portion of the housing. Instead, we must simply ascertain what the patentee meant by “supported rotatably in the movable portion.” To answer this question, we look to the Specification, which “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315. “The construction that stays true to the claim language and most naturally aligns with the patent’s description of the invention will be, in the end, the correct construction.” Id. at 1316. Here, it is undisputed that in the sole embodiment described by the ’121 patent, the thrust-bearing element is supported by and entirely within the movable portion of the housing. Ex. 1001, Figs. 1, 2; Pet Post-Hearing Resp. 1; PO Post-Hearing Resp. 2. Construing “in the movable portion” to require the thrust-bearing element to be entirely within the movable portion both “stays true to the claim language and most naturally aligns” with the sole disclosed embodiment. Such a construction does not import the word “entirely” from the sole embodiment into the claims because the construction “arises from the claim language itself.” See SharkNinja Operating LLC v. iRobot Corp., 2024 WL 1132219, *2–*3 (Fed. Cir. 2024) (construing “primary brush assembly disposed within the round housing perimeter” to require that the primary brush assembly be “entirely within” the round housing perimeter is not an improper incorporation of “entirely” from embodiments into the claims because the construction “arises from the claim language itself”). Accordingly, having reviewed the complete record and the parties’ pre- and post-hearing briefing, we determine that “supported rotatably in the movable portion” means supported rotatably entirely in the space defined by the movable portion.” slip op. at 25

      “b. When “Thrust-Bearing Element” is Construed as a Means-Plus-Function Claim Limitation, there is Insufficient Evidence in the Record to Support a Finding that VenHuizen Discloses a Thrust- Bearing Element that is Supported Rotatably in the Movable Portion As noted above, Petitioner contends that VenHuizen’s shaft 55, retaining hub 56, and handle 58 together constitute the claimed thrust-bearing element “under a proper means-plus-function definition.” Pet. Reply 18–19.12 We do not discern sufficient evidence of record or persuasive technical reasoning from Petitioner to support a finding that these elements together are “supported rotatably in the movable portion” of the housing, as claim 1 requires. Ex. 1001, 4:38–39. We construed this limitation to require the thrust-bearing element to be supported rotatably entirely in the space defined by the movable portion (the space defined by VenHuizen’s second housing member 90). Petitioner does not contend, much less show, that these components are supported rotatably entirely in the movable second housing member 90. On the contrary, of the three components constituting VenHuizen’s thrust-bearing element, all of retaining hub 56 and most of shaft 55 are located in the fixed portion of the housing (first housing member 50), not the movable portion 90. See Ex. 1001, Fig. 6. Only handle 58 is ever located in the movable portion (when the fixed and movable portions are joined together). See id. Accordingly, Petitioner has not shown that VenHuizen discloses a thrust-bearing element rotatably supported in the movable portion.” slip op. at 35
