    “For purposes of this Decision, we adopt Petitioner’s definition of a POSITA. Petitioner’s witness (Mr. Cook) qualifies as a POSITA under this definition, and, therefore, is qualified to opine from the perspective of a POSITA on technical matters included within the areas of expertise prescribed by the definition. As indicated above, Petitioner’s definition of a POSITA does not require education in the field of optics and professional experience designing or analyzing optical apparatus, unlike Patent Owner’s definition. We are aware, however, that Patent Owner’s witness (Dr. Klopp) has more extensive experience with optical systems and methods than Petitioner’s witness (Mr. Cook). Compare Ex 1003 ¶¶ 8–14, Ex. 2005, 39:21–59:17, with Ex. 2003 ¶¶ 3–20, Ex. 2004, 1–2, Ex. 1015, 10:22–13:25. Although Mr. Cook possesses excellent credentials in the field of mechanical engineering, his experience in the design and analysis of optical systems and methods is sparse and insubstantial compared to that of Dr. Klopp. Id. Due to this difference in experience levels, in instances where the witnesses express differing views on factual issues related to optical systems and methods, we accord more weight to Dr. Klopp’s testimony than to Mr. Cook’s.” slip op. at 9

Petitioner asserts that because Tseng’s shower head is designed to be pulled out, the wire is subject to stress and strain, which could lead to failure over time. Id. (citing Ex. 1003 ¶¶ 251–253). According to Petitioner, incorporating Mizuno’s hydroelectric generator into Tseng’s shower head would obviate the need for an external power supply or battery, which would reduce installation and operation costs, prevent a potential wiring failure, and eliminate periodic battery replacement. Id. at 45 (citing Ex. 1003 ¶¶ 257–260). Petitioner asserts that a person of ordinary skill in the art, therefore, would have been motivated to incorporate Mizuno’s hydroelectric generator into Tseng’s shower head, and would have had a reasonable expectation of success in doing so because Mizuno’s hydroelectric generator is designed and intended to be integrated into a faucet’s shower head to reliably power LEDs. Id. at 45–46 (citing Ex. 1008 ¶¶ 1, 2). Patent Owner counters that a person of ordinary skill in the art would not have had any reason to modify Tseng in view of Mizuno. Prelim. Resp. 32. Patent Owner contends that Tseng expressly set out to develop a design that includes electrical wiring, and did so successfully by improving the integration of electrical wiring into its shower head design. Id. at 33–34 (citing Ex. 1004 ¶¶ 9, 102–110). Patent Owner further contends that a person of ordinary skill in the art would not have been motivated to completely redesign Tseng’s shower head to change the power source entirely to eliminate wiring. Id. Patent Owner contends that a person of ordinary skill in the art also would not have had a reasonable expectation of success in incorporating Mizuno’s hydroelectric generator into Tseng’s shower head because Tseng explicitly discloses that the space in its shower head is narrow. Id. at 36 (citing Ex. 1004 ¶¶ 7, 108). According to Patent Owner, Mizuno’s hydroelectric generator requires room for additional components beyond the hydrogenator, including a voltage stabilizer, cooling components, and a relief valve, which Patent Owner contends would have discouraged the ordinarily skilled artisan from a major redesign of Tseng’s faucet necessary to incorporate these elements. Id. at 37. We have considered Petitioner and Patent Owner’s assertions for ground 2.

    “The disclosures of the ’864 patent thus align with the Patent Owner’s position that the recitation of a “CO to CO2 combustion promoter” in claim 1 constitutes a claim limitation because the disclosures show that the phrase is “necessary to give meaning to the claim[s] and properly define the invention” as described in the patent. In re Fritch, 972 F.2d 1260, 1262 (Fed. Cir. 1992); see also Kropa v.

The Patent Owner thus provides factual and legal bases for determining that a “CO to CO2 combustion promoter,” as recited in the preamble of claim 1, is a claim limitation. By not taking a position as to whether a “CO to CO2 combustion promoter” constitutes a claim limitation, the Petitioner does not establish that this recitation is not limiting. We determine that the intrinsic evidence of record is sufficient to establish that a “CO to CO2 combustion promoter” is a limitation of claim 1 because the evidence shows that this phrase is necessary to give meaning to the claim and to properly define the invention.

    “review. 35 U.S.C. § 314 (2018); 37 C.F.R. § 42.4(a) (2022). The standard for institution is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted “unless the Director determines . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons set forth below, we determine that Petitioner demonstrates a reasonable likelihood of prevailing with respect to at least one claim of the ’740 patent. Accordingly, we grant institution of an inter partes review.” slip op. at 2

  • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateOther

    “the application describe the claim limitations exactly,” the application must demonstrate to persons of ordinary skill in the art that the applicants invented a composition including those limitations. 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

  • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportPriority date, deniedOther

    “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

  • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Instituted

    “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. Ex. 1005 ¶¶ 45, 47, 53, 57; Ex. 1001, 21:48–51, 22:53–56, 33:35–36, 34:12–13. 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. Patent Owner does not address Petitioner’s anticipation arguments with respect to claims 19–61 and 63–75, apart from arguing that Doud is not prior art to these claims. Prelim. Resp. 27–39. demonstrates a reasonable likelihood that claims 19–61 and 63–75 are anticipated by Doud.” slip op. at 16

    “The Petitioner proposes that a person of ordinary skill in the art “would have had at least a bachelor’s degree, or the equivalent degree, in mechanical engineering, chemical engineering, or a related field, and 2–3 years of experience in the research, design, or development of portable oxygen concentrators and related hardware, software, and firmware, or equivalent experience.” Pet. 21 (citing Ex. 1003 ¶¶ 226–229). The Petitioner further proposes that “[a] person with less education but more relevant practical experience, or more education and less experience, may also meet this standard.” Id. At this stage of the proceeding, the Patent Owner does not dispute the Petitioner’s proposed definition of a person of ordinary skill in the art. Prelim. Resp. 14. We find, at this stage, that the asserted prior art itself is sufficient to demonstrate the level of ordinary skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself can reflect the appropriate level of ordinary skill in the art). To the extent a more precise definition is required, we apply the Petitioner’s unopposed definition for purposes of determining whether to institute review, because it is consistent, on this record, with the disclosures of the asserted prior art references.” slip op. at 17

    “The Petitioner presents express constructions for three claim terms: “separation cartridge,” “receptacle,” and “selectively removable.” Pet. 21– 26. Although the Patent Owner contests the Petitioner’s proposed constructions of these terms, the Patent Owner proposes an alternative construction of only the term “separation cartridge.” Prelim. Resp. 14–23, particularly 20. Nonetheless, the Patent Owner further indicates that construction of “separation cartridge,” “receptacle,” and “selectively removable” is not needed at this stage because the Petitioner’s proposed constructions are “not related to any controversy in this IPR proceeding.” Prelim. Resp. 14–23, particularly 16. Taking into consideration the information presented, we determine that none of the claim terms requires express construction for purposes of deciding whether to institute review.” slip op. at 18
