Wertheim, 541 F.2d at 262. On its face, the range of “at least 0.01 wt. %” encompasses a range that is broader than 0.01–35 wt. %, and Patent Owner does not sufficiently explain why a person of ordinary skill in the art would understand from merely a disclosure of 35 wt.% that the inventors were in possession of the entire claimed range for copper, cobalt, or nickel in the magnesium composition.” slip op. at 11

“On this record, the term “at least 0.01 wt. %” in the ’740 patent encompasses values for nickel, copper, and cobalt that are higher than the 35 wt. % (nickel and copper) and 20 wt. % (cobalt) limits outlined in the parent and grandparent applications. Accordingly, we determine that there is a reasonable likelihood that claim 19 of the ’740 patent is not entitled to the benefit of the filing dates of its priority applications. Challenged claims 20–61 and 63–75 depend from claim 19 and there is no argument presented that these claims have independent written description support in Doud. For example, there is no evidence presented that any of these dependent claims narrow the ranges for each of copper, nickel, and cobalt recited in in the ’295 application for these claims.7 Accordingly, for purposes of this Decision, we apply Doud as prior art to challenged claims 19–61 and 63–75.” slip op. at 12

“as the ’740 patent. For example, Doud and the ’740 patent both disclose a method of forming a novel magnesium composite that includes melting an AZ91D magnesium alloy containing 90 wt. % magnesium, 9 wt. % aluminum, and 1 wt. % zinc. Ex. 1005 ¶¶ 45, 47; Ex. 1001, 21:43–51, 22:48–53, 33:32–43, 34:9–12. To this alloy is added either 7 wt. % nickel or 10 wt. % copper.

These additives are mixed in the magnesium alloy at a temperature that is less than the melting point of copper or nickel, and the casting is then cooled. Ex. 1005 ¶¶ 45, 47, 53, 57; Ex. 1001, 21:51–54, 22:56–58, 33:35, 34:12-13. Doud reports that nickel and copper, when added to molten magnesium, will form Mg2Ni and CuMg2 intermetallic, galvanically-active, in situ precipitates. Ex. 1005 ¶¶ 12–13. Doud discloses that the dissolution rate of the resulting casting material is either 325 mg/cm2-hr (nickel) or 50 mg/cm2-hr (copper) in a 3% KCl solution at 90° C. Ex. 1005 ¶¶ 45, 47, 53, 57; Ex. 1001, 21:60–62, 22:61–63, 33:41–43, 34:15–17. Doud also discloses that the average particle diameter of the additives used in the invention is generally “at least about 0.1 microns” and “typically no more than about 500 microns.” Ex. 1005 ¶ 6. Petitioner explains how the identified disclosures of Doud anticipate independent claim 19. Pet. 39–40. Petitioner also identifies where the limitations of dependent claims 20–61 and 63–75 are disclosed in Doud. Id. at 41–45.

“The express language of claim 1 requires no solubility threshold, and dependent claim 10 of related U.S. Patent No. 10,288,620 B2 demonstrates that, where a solubility threshold was intended by the inventors of these patents, they knew how to expressly set forth that threshold in the claims. Compare Ex. 1004, 222:47–49 (“capable of imparting solubility in water”), with Ex. 1005, 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’648 patent explains that “each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Ex. 1004, 2:21–22; Prelim. Resp. 17. This solubility threshold, however, is not in claim 1. Also, the ’648 patent states that this solubility applies only to some embodiments. See, e.g., Ex. 1004, 53:9–12, 55:6–20. We decline to import such a limitation from the written description into claim 1 absent reason for doing so. See SciMed Life Systems, Inc. v.

The district court stayed the litigation “pending resolution of the IPR proceedings that have been instituted on the patents at issue in this case.” Ex. 2006, 2. Regarding the length of the stay, the district court explicitly ordered the parties not to use continuance of the fact discovery to October 28, 2022 “as grounds for . . . opposing institution of any post-grant proceeding.” Ex. 2007, 2. Regarding when the stay will be lifted, the order merely gives Patent Owner the opportunity to “seek to lift the stay as to any patents that are not instituted for review.” Ex. 2006, 2 (emphasis added). But we decline to speculate whether the district court would grant such a motion directed only to one of the six patents. Among the reasons warranting a stay of the litigation, the district court found “IPR has the potential to streamline issues for trial” and “the resources the parties will need to expend for experts could be significantly impacted by the outcome of any instituted IPR proceedings.” Id. Thus, the litigation is stayed pending the outcome of the six related proceedings, not merely the outcome of this institution decision, and the district court stayed the litigation for the explicit purpose of gaining efficiency and avoiding duplication of efforts by letting this inter partes review proceed to its conclusion first.14 See Prelim.

“proposed construction of a photosensitizer as a substance that makes a target substance more sensitive to light accords with the plain and ordinary meaning of the term in the context of the claims and specification of the ’706 patent, whereas Petitioner’s proposed construction is unduly narrow. Although a photosensitizer may be “a light-reactive substance that, when exposed to light, initiates a change in another substance,” as Petitioner proposes, we are not persuaded that the claim term should be limited to only this specific type of photosensitizer. Neither the claims nor the specification expressly qualify or otherwise limit the word “photosensitizer” in any way. The Specification includes a discussion of two prior art references (Biel and Albrecht) that apply light-reactive dyes as photosensitizers, and states that the methodologies used in these references “suffer[] from the significant practical disadvantage that photosensitising agents must be applied to the bacteria that are to be inactivated.” Ex. 1001, 2:10–15. According to the ’706 patent, “[t]he need for photosensitising agents is a significant limitation of these techniques.” Ex. 1001, 2:17–19. We agree with Patent Owner that these statements in the ’706 patent specification refer to the “practical disadvantage” of applying photosensitizers in general, which is an inherent disadvantage in any photosensitizer applied before inactivation. See PO Resp. 11, 14–15. We are not persuaded by Petitioner’s argument that the ’706 patent was referring” slip op. at 12

“Ex. 10235 ¶¶ 68–76). Patent Owner does not address the definition of a person of ordinary skill in the art in its Response or Sur-reply, but Patent Owner’s declarant, Raymond Goodrich, Ph.D., testified that a person of ordinary skill in the art “would have had a combination of experience and education in chemistry, photochemistry, biochemistry, bacteriology, microbiology and/or infectious disease” including “at least a bachelor degree of science degree in one or more of these areas and at least two years of work experience in at least one of these fields.” Ex. 20016 ¶ 23. Dr. Goodrich also indicated that all of his opinions would apply equally under Petitioner’s definition of a person of ordinary skill in the art. Ex. 2001 ¶ 24. In view of the large degree of overlap between the parties’ definitions, and Dr. Goodrich’s statement that his opinions would apply under either definition, we adopt Petitioner’s proposed definition, such that a person of ordinary skill in the art would have had “at least a bachelor of science degree in one of the areas of molecular biology, biochemistry, microbiology, or infectious diseases, and likely a doctoral degree in one of these subjects, with several to many years of experience with bacterial inactivation techniques.” Pet. 18. This level of skill is consistent with the field of endeavor of the ’706 patent and the disclosures of the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“We are not persuaded by Petitioner’s argument. Although Petitioner cites to a paragraph in the Sulzinski Reply Declaration to support the argument that the MRSA would have been rinsed of any ALA, Dr. Sulzinski merely states that this is his opinion, and offers no evidence to support that statement. Ex. 1033 ¶ 77. Without disclosing the underlying facts or data forming the basis for this opinion, this testimony is entitled to little or no weight. 37 C.F.R. § 42.65(a). Additionally, even if we were to agree that all of the MRSA would have been rinsed of any ALA prior to exposing it to light, the outcome here would not change because Nitzan used a photosensitizer when it incubated the MRSA in ALA. The fact that Nitzan later rinsed the MRSA does not change the fact that Nitzan used a photosensitizer as part of its method, as precluded by claims 1 and 3.” slip op. at 23

“(internal citations omitted). It is also undisputed that Nitzan tested the photoinactivation of MRSA with and without the addition of ALA, and that MRSA, like the P. acnes tested in Ashkenazi, is a Gram-positive bacteria. Ex. 1009, 431; Ex. 1010, 17; PO Resp. 35; Pet. 45–46. Further, as Petitioner points out, Nitzan identified studies showing the successful inactivation of P. acnes when discussing “approach[es] for photoinactivation of bacteria.” Ex. 1009, 430; Reply 2. This evidence supports Petitioner’s argument that a person of ordinary skill in the art would have been prompted to employ and adapt “Ashkenazi’s known technique of inactivating P. acnes in the absence of exogenous ALA for the purpose and benefit of inactivating MRSA in the absence of exogenous ALA.” Pet. 45–46; Ex. 1023 ¶ 163. The evidence also supports Petitioner’s arguments that it would have been obvious to try to inactivate MRSA in the absence of exogenous ALA using Ashkenazi’s techniques. Pet. 47; KSR, 550 U.S. at 421. Ashkenazi showed one type of Gram-positive bacteria could be inactivated with 407– 420 nm light in the absence or presence of ALA. Nitzan showed another type of Gram-positive bacteria (MRSA) could be inactivated with the same visible light in the presence of exogenous ALA. These facts support Petitioner’s assertion that “the next logical step” would be to try inactivating MRSA in the absence of exogenous ALA using the same visible light used in Ashkenazi.

“In our Decision, we reviewed BASF’s arguments and submitted evidence, and concluded that the record lacked sufficient support for these three links in BASF’s logical chain. First, we found that BASF had not provided evidence “why a person of skill in the art would have been led by Park’s strength requirement for an air intake system to select Formulation D” for the evaporative emissions systems that are the focus of the ’844 patent. Dec. 17–18. Second, we found no reason to conclude that, even if a person of ordinary skill in the art would have selected Park’s Formulation D to use in an evaporative emissions system, the resulting honeycomb would have the 73.8% voidages that Park considers desirable. Id. at 18–19. Finally, we found unsupported Mr. Lyons’ testimony that BAX 1500 carbon was the highest-capacity carbon known in the art at the time of the invention. Id. at 19–20. Each of these independent findings was sufficient to lead us to conclude that BASF had not shown that a system resulting from the use of Park’s honeycomb filter in an evaporative emissions system would necessarily have an IAC below 35 g/L, as required by the claims. Id. at 20–21. As such, we found that BASF had not established a reasonable likelihood that any claim of the ’844 patent was unpatentable.” slip op. at 4

“insufficient to support a reasonable likelihood of inherency on this record. To justify a conclusion of inherency in an obviousness inquiry, “the limitation at issue necessarily must be present, or the natural result of the combination of elements explicitly disclosed by the prior art.” Par Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1196 (Fed. Cir. 2014). In other words, even were we to accept BASF’s contentions that a person of ordinary skill would have formed a filter using Park’s Formulation D and having 73.8% voidages, we would also have to conclude that the artisan would have had reason to select a carbon that necessarily would result in an IAC below 35 g/L. And, as we stated in our Decision, the reason for selecting a particular carbon cannot be based on the very IAC property that is allegedly inherent. Dec. 14 (“properties that are inherent—and, therefore, possibly unknown—cannot be used as the basis for this motivation unless they were expected.”) (citing Honeywell Int’l v. Mexichem Amanco Holding, 865 F.3d 1348 (Fed. Cir. 2017)). BASF’s Petition discussed two available carbons, BAX 1100 and BAX 1500, because they were referenced in the specification of the ’844 patent. Pet. 23. But there is insufficient evidence in the record why these were the two carbons that a person of ordinary skill in the art would have found it obvious to select from among the carbons that were available at the time of the invention, and the record is silent as to whether other carbons, if selected, would have necessarily resulted in the same IAC or lower. As we observed in our Decision, all that BASF presented on this point was the unsupported testimony of its expert that BAX 1500 had “the highest possible IAC known at the time of the ’844 patent.” Dec. 19–20 (citing Ex. 1003 ¶ 111). Again, BASF cites our rules, contending that we erred by not viewing a disputed issue of material fact in the light most favorable to it. Req. Reh’g 14. In particular, BASF notes our statement in the Decision acknowledging that “BAX 1500 certainly has the highest IAC of any carbon disclosed in the ’844 patent,” and argues that this alone is “evidence in the record that BAX-1500 was the highest-capacity carbon available at the time.” Id. (citing Dec. 20). But the disclosure of two particular carbons in the record says nothing about the existence—or lack thereof—of other carbons. In other words, as we stated in the Decision, “on this record we cannot extrapolate beyond [the] disclosure to all activated carbons known at the time of the invention.” Dec. 20. The issue is not one of viewing a disputed issue of fact in the light most favorable in BASF; rather, it is an issue of BASF asking us to conclude from the disclosure of two carbons in the ’844 patent that these are the carbons that a person of ordinary skill in the art, upon reading Park, would have selected. The record is insufficient to reach such a conclusion, and we did not err in deciding so.” slip op. at 9

“would have selected Park’s Formulation D when creating a filter for use as a subsequent adsorption volume, BASF contends that we misapprehended its evidence supporting such a selection. Id. at 9–12. BASF notes its argument was that a person of ordinary skill in the art would have selected Formulation D “because it is the only formulation that meets Park’s explicit requirements for the air intake application: a carbon content of 25–35% by weight and an axial crushing strength from 1200–1600 psi.” Id. at 10 (citing Pet. 33–34). But BASF’s argument misses the point of our conclusion in the Decision, which was that the record contained no evidence that the requirements of an air intake application, as discussed by Park, were the same as the requirements of the evaporative emissions application that is the focus of the ’844 patent and the primary prior art references in each combination. In other words, while a person of ordinary skill in the art might have been led to Formulation D if trying to create a filter for an air intake system, the record contains no persuasive evidence that the same is true of the artisan creating an evaporative emissions system. Indeed, as we noted in the Decision, the only evidence on this point is to the contrary, and comes from Ingevity’s expert witness Dr. Ritter. As we noted, “Dr. Ritter testifies that evaporative emission systems and air intake systems are designed for use with different vapor concentrations and, more importantly, different flow rates.” Dec. 17 (citing Ex. 2001 ¶¶ 43–44).” slip op. at 5

As discussed in our Decision, Petitioner satisfied its initial burden of production on the issue of whether Gwozdz is prior art by establishing that Gwozdz is entitled to the effective filing date of the Gwozdz provisional.

Thus, the burden of production shifts to Patent Owner, who must show not only the existence of earlier applications, but also how the written description in the earlier applications supports the challenged claims. Dynamic Drinkware, 800 F.3d at 1379–80. “[T]o gain the benefit of the filing date of an earlier application 4 under 35 U.S.C. § 120, each application in the chain leading back to the earlier application must comply with the written description requirement of 35 U.S.C. § 112.” Zenon Envtl., Inc. v.

Thus, as discussed in our Decision, Patent Owner must show that each application in the priority chain1 makes the requisite disclosure of subject matter; otherwise, the ’876 patent is not entitled to the benefit of the filing date of the ’558 provisional. Decision 7 n.6. On this record, Patent Owner fails to satisfy its burden of production to show entitlement to an earlier filing date. All of Patent Owner’s arguments are focused on the alleged deficiencies with Petitioner’s contentions regarding the disclosure of alkyl glycosides in the ’558 provisional. Prelim. Resp. 24–27.
