Patent Owner did not address this issue in the Sur-reply.

    “Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). At first glance, the language of the limitation at issue—which, again, recites “the compressed air and the operative fluid mix together in said mixing chamber to form the fluid dispersion”—would seem to require the “fluid dispersion” (under the stipulated construction) to be fully formed in the “mixing chamber.” In other words, the language of the limitation alone would seem to support Patent Owner’s proposed construction for the “form the fluid dispersion” limitation. But the claim construction analysis does not end with consideration of the claim language alone. Next, we turn to the Specification. The Federal Circuit has said that the specification “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)). Here, the discussion in the Specification of precisely the same language as in the limitation at issue strongly supports that “to form a fluid dispersion” in the limitation at issue requires only initial mixing of the compressed air and operative fluid in the mixing chamber, with further “formation” of the ”fluid dispersion” occurring downstream of the mixing chamber: More importantly, the “predetermined amount” of compressed air and the “preselected amount” of the operable fluid are initially mixed together in the mixing chamber 226 to form a fluid dispersion. The diffusion chamber 112" is further structured to facilitate the formation of a plurality of substantially uniform droplets, as defined hereinabove, in the fluid dispersion prior to discharge from the diffusion chamber 112" through discharge port 132. Ex. 1001, 10:62–11:2 (emphasis added) (discussing Figure 6), quoted, in part, at Pet. Reply 6–710; see also Ex. 1001, 5:64–6:4 (same language, except without double primes, in a discussion of Figures 1 and 2). To be sure, certain passages in the Specification could be read to indicate that a “fluid dispersion” must be fully formed in the “mixing chamber.” See, e.g., Ex. 1001, 6:11–12 (“More in particular, the suppression chamber 232 receives the fluid dispersion from the mixing chamber 226.”); see also id. at 7:22–33, 11:39–52 (both implying that a “fluid dispersion” is formed in the mixing chamber). But the passage block quoted directly above (and the similar one bridging columns 5 and 6) more directly addresses the issue at hand—i.e., the scope of “form the fluid dispersion”—by using the same” slip op. at 13

    “To satisfy its burden of proving obviousness, a petitioner cannot employ mere conclusory statements. The petitioner must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016); TriVascular, Inc. v. Samuels, 812 F.3d 1056, 1066 (Fed. Cir. 2016) (“Although the KSR test is flexible, the Board ‘must still be careful not to allow hindsight reconstruction of references . . . without any explanation as to how or why the references would be combined to produce the claimed invention.’”) (citation omitted). Based on the complete record, we agree with Patent Owner that “Petitioner’s asserted motivation boils down to the conclusory statement that given Goubet and Kaiser, ‘it was well known in the field at the time of the invention that droplets of greater uniformity result in uniform droplet evaporation.’” PO Resp. 31 (quoting Pet. 59). We agree with Patent Owner that Petitioner’s discussion of the alleged reasons to combine (Pet. 59) is insufficient to support the proposed combination here. See Magnum Oil, 829 F.3d at 1380. Specifically, we are not persuaded that Kaiser’s teachings—which relate to combustion (Ex. 1014 at 43)—would have led one of ordinary skill in the art to the proposed modifications, which would allegedly “improve the smoothness (i.e., less harsh) of the aroma generated as the oil droplets evaporate in the surrounding airspace.” See Pet. 59 (emphasis added); White Pet. Decl. ¶ 251 (same); see PO Resp. 32 (“Rather, Dr. White merely describes the ability to achieve the effect as in the claimed patent, not why a [person of ordinary skill in the art] would look to the field of electrospray injection and combustion in mesoscale power-generation systems, using high-voltage electric fields to generate charged fuel droplets for controlled combustion in catalytic micro-combustors when considering atomization for scents.”). For these reasons, we determine, in light of the complete record, that Petitioner has not shown by a preponderance of the evidence that one of ordinary skill in the art at the time of the invention would have had reason to combine Goubet and Kaiser, as proposed. slip op. at 32

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).

It is also not disputed that Guoxin, Ho, Calmettes, Hall, Kimber, and Schuster were not previously presented to the Office. See Prelim. Resp. 33. Patent Owner argues that Guoxin, Brown, and Ho are cumulative of a reference, DeMarco9, that was previously presented to the Office and relied upon to reject the claims. Prelim. Resp. 33 Patent Owner argues that Guoxin, Brown, and Ho are cumulative to DeMarco because all of the “references are completely silent as to whether the purported ‘extended portion’ is integrally molded with the purported body of the toiled fill valve.” Id. at 33–36. Patent Owner’s arguments are unpersuasive. As can be seen from our discussion of Ho in our analysis below, on this record, we are persuaded that Petitioner has sufficiently shown for purposes of institution how Ho allegedly teaches the claimed integrally molded extended portion. We, thus, are not persuaded that at least Ho is cumulative of DeMarco. Grounds 1–4 rely upon combinations of prior art that include Ho. Ground 5 is based upon Schuster, which was not previously presented to the 9 U.S. Patent No. 5,708,991 (Ex. 1024). Office. Accordingly, we determine that discretionary denial is not warranted. Because we determine that part one of the framework is not satisfied, we need not turn to part two to determine whether Petitioner demonstrates that the Office erred in a manner material to the patentability of the challenged claims.

    “On this record, we are persuaded by Patent Owner that the claim phrase “integrally molded with” should be construed to mean “molded together as a single structure” and to exclude items created as separate pieces and attached together later. Patent Owner’s construction is consistent with the plain language of the claims, which requires the extended portion be “integrally molded with” the body and not just the extended portion be integral with the body. Further, we determine that Patent Owner’s construction is consistent with the ’105 patent, which discloses that “the bowl fill valve 109 may be molded as a portion of the toilet fill valve 100 or it may be snapped or clamped into place, or it may be attached to the toilet fill valve 100 in some other manner, etc.” Id. at 2:23–26 (emphasis added).

Petitioner asserted motivation to combine — improved strength and integrity of connection — is supported by the testimony of Dr. Cameron.

    “product ordered by the customer is available and does not contemplate a scenario where the product is unavailable or otherwise describe the action to be taken if the product is unavailable. See Pet. 17–22. We agree, at least based on the preliminary record. In particular, with reference to Figures 2 and 3, the ’848 parent application describes a method where (1) a customer chooses “a store where a desired product is being sold” (step 105), (2) the customer selects a delivery agent and sends an “acquisition request” to the delivery agent (steps 108, 109, 110), and (3) “the selected delivery agent travels to the store location . . . and finds the desired product to be acquired” (step 113). Ex. 1011 ¶¶ 17, 20, 23 (emphasis added). “The delivery agent then communicates to the customer that the product has been identified, and the customer has the option of inspecting the product in real-time” (step 117). Id. ¶ 23 (emphasis added). “Next, the customer either approves or rejects acquisition of the inspected product” (steps 119, 120, 122). Id. ¶ 24 (emphasis added). That description in the ’848 parent application clearly presumes that the product ordered by the customer has been located and is available for inspection, which is at odds with the additional requirements of claims 1 and 14 of “failing to locate an identified product” and “determining that the identified product is not available.” Ex. 1001, 11:20 (claim 1), 12:30 (claim 14) (emphases added). To the extent Consumeron argues otherwise, we are not persuaded at this preliminary stage. According to Consumeron, the customer’s rejection of the product means that “the agent fails to locate a product that is satisfactory.” See Prelim Resp. 11. But nowhere do we discern that the ’848 parent application hinges the identity and availability of a product on whether it is satisfactory to the customer. That a product might not meet a customer’s satisfaction does not negate the description in the ’848 parent application that the agent locates and identifies the product in the first instance before giving the customer the option to inspect and reject the product. Indeed, because the customer placed the online order with a store advertising the product, the presumption is that the advertised product is available and satisfactory to the customer.8 And, while conceivably the purchase of a product cannot be fulfilled in the event the product is unavailable, it would seem to be improper hindsight to derive written description support by “[w]orking backward from a knowledge of the claims.” Novozymes A/S v. DuPont Nutrition Biosciences APS, 723 F.3d 1336, 1349 (Fed. Cir. 2013). “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed. It extends only to that which is disclosed.” Lockwood v. American Airlines, Inc., 107 F.3d 1565, 1571–72 (Fed. Cir. 1997). Thus, based on the preliminary record, the ’848 parent application does not provide sufficient written description for the terms noted above. As such, we find that Instacart demonstrates a reasonable likelihood it will prevail in showing that the asserted references are prior art to the challenged claims.” slip op. at 6

Instacart provides a detailed mapping of how Carr satisfies all the recited limitations of claim 1, except limitation [1.0.3], for which Instacart points to Lauka. See id. at 35–44.

See Pet. 31–34 (citing Ex. 1003 ¶¶ 86–96); see also id. at 37 (“In view of the teachings of Lauka, a POSITA would have recognized that it was obvious to implement the UPC scanner functionality of Carr’s handheld device using an ‘imaging device’ such as that taught by Lauka, which specifies that the ‘imaging device 206 can comprise a video or still camera’ and ‘can be used to capture images.’ Ex.1006, 3:49-57; Ex.1003, ¶¶105- 107.”).” slip op. at 11
