“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

“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.

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.

“On the present record and for the purpose of this Decision, we agree with Petitioner that the proper construction of “communications unit” encompasses multiple DRUs or antenna units. Although Patent Owner is correct that not every embodiment needs to be reflected in every claim, and indeed, some embodiments may not appear in any claim, we do not agree that there is evidence supporting Patent Owner’s argument that the construction of “communications unit” should be narrowed to the embodiment requiring only one DRU/antenna. The cited claims do not indicate that multiple units may not transmit at the sets of frequencies recited. Additionally, although Patent Owner cites claim 16 as requiring that each communications unit is a single DRU, if that were a correct reading of claim 16, it is not clear what the claim recitation would add, as it would not narrow the prior recitation of a “communications unit” from claim 15. Such interpretations are disfavored. See Cat Tech LLC v. TubeMaster, Inc., 528 F.3d 871, 885 (Fed.

In contrast, § 311(b) permits challenges “on the basis of prior art consisting of patents or printed publications.” The language in § 311(b) implies that, unlike CBMs, IPRs are not limited to prior art challenges solely under § 102(a).

“provide a specific numerical analysis of the number of LEDs necessary to match a value of the DC output voltage in Nerone. PO Resp. 31–32. Based on Dr. Baker’s testimony, Petitioner provides several factors that a person of ordinary skill in the art would have considered when designing Nerone’s circuitry to satisfy the “matching” requirement of limitation 7(f). Pet. 18 (citing Ex. 1002 ¶ 120). Dr. Baker supports his testimony concerning the knowledge of these factors by one of ordinary skill with reference to disclosures in Cross and Martin. Ex. 1002 ¶¶ 121–123. Neither Patent Owner nor Dr. Ducharme dispute that a person of ordinary skill in the art would have known to consider these factors when designing Nerone’s circuit. See PO Resp. 30–43; Ex. 2001 ¶¶ 89–106. Petitioner then explains how a person of ordinary skill in the art would have used these factors to apply the teachings of Martin to configure Nerone’s circuitry so that “the forward voltage of the series-connected LEDs [] approximately match[es] the rectified AC voltage output of the above-described LED driver circuit.” Pet. 21; id. at 20–21; see also Ex. 1107 ¶ 29 (“a person of ordinary skill in the art would have understood and would have been capable of determining the appropriate number of LEDs based on the application and design of Nerone’s system such that the forward voltage drop of the LEDs . . . matches the rectified AC voltage output . . . to mitigate against overdriving or underdriving the LEDs.” (citing Ex. 1074 ¶¶ 30–31, Fig. 2)). For these reasons, we find that it was not necessary for Petitioner to provide a specific numerical calculation of the number of LEDs in its proposed modification of Nerone. We also agree with Petitioner that “matching the input voltage to the forward voltage of the LEDs had become a matter of routine optimization.” Pet. 19. Patent Owner contends that this statement is “vague and conclusory.” Sur-reply 12–13. Petitioner, however, supports this statement with the testimony of Dr. Baker. Ex. 1002 ¶¶ 120–123. Dr. Baker’s testimony, which we credit, is corroborated by both Cross and Martin. See id. (citing Ex. 1015 ¶¶ 2, 21, 22 Fig. 5; Ex. 1074 ¶ 30). In particular, Cross specifically discloses that “[t]he number of LEDs employed will vary with the intended lighting application and the value of the rectified DC voltage, wherein optimization of such is well within the skill of those in the art.” Ex. 1074 ¶ 30. Patent Owner does not dispute Cross’s statement that optimizing the number of LEDs is within the skill of an ordinarily skilled artisan. See PO Resp. 40. Martin chooses the number of LEDs “such that the maximum voltage across each individual LED . . . is low enough so as to not damage the LEDs.” Ex. 1015 ¶ 22. It also specifically discloses that “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series.” Id. (emphasis added). Consequently, Martin uses “voltage matching” to determine the number of LEDs so as not to damage the individual LEDs. See also Ex. 1002 ¶¶ 120–124 (Dr. Baker explaining that a skilled artisan “configuring Nerone’s circuit 400 would have recognized that the forward voltage of the series-connected LEDs should approximately match the rectified AC voltage output of the above-described LED driver circuit.” Id. ¶ 124.).

See, e.g., Exs. 1009 (Hack), 1022 (Gillespie); Pet. 43 (citing same).13 Patent Owner does not offer any contrary evidence that would undermine Dr. Baker’s persuasive testimony that a POSITA would have understood that the modified device would use an LED touch display and that when touched, the LED(s) of the display would change (and thus provide light). See Ex. 2001 ¶¶ 105–16 (attacking the sufficiency of Petitioner’s evidence but not disputing Dr. Baker’s core assertion regarding the understanding of a POSITA). It is somewhat ironic that Patent Owner asserts that Dr. Baker’s testimony is “conclusory and not tied to supporting evidence.” Sur-reply 26 (citing Ex. 1002 ¶ 141). In reality, Petitioner supplies ample supporting evidence (e.g., Hack and Gillespie), but Patent Owner denies that we can consider it. See, e.g., Pet. 43 (citing, e.g., Exs. 1009, 1022); PO Resp. 44. Petitioner’s reliance on evidence to show the understanding of a skilled artisan is appropriate because “the obviousness ‘analysis requires an assessment of the . . . background knowledge possessed by a person having ordinary skill in the art.’” Koninklijke Philips, 948 F.3d at 1337. Petitioner does not rely upon references such as Hack and Gillespie to supply a missing claim limitation.14 Rather, Petitioner relies on Butler’s disclosure of a touch screen for this limitation and points to Hack and Gillespie to show that prior art touch screens often included LED displays and that one of ordinary skill in the art would have understood that a touch screen would have provided 13 As we explain below, we need not rely on Swartz. 14 For this reason, Petitioner need not have included Swartz, Hack, or Gillespie in its ground listing, and Petitioner need not show a motivation to combine Swartz, Hack, or Gillespie with Piepgras, Michael, and Butler. light based upon detection of human touch.

“We disagree. It is clear from the plain language of claim 1 that the claimed “cleaning composition” is a composition for cleaning that includes four named components and has a specified pH. Ex. 1001, 29:2–9. The ’329 patent specification unambiguously teaches that the cleaning composition is for removing residues from semiconductor substrates. Id. at 1:23–29, 2:10–12, 2:17–33, 15:52–55. Although the ’329 patent describes a cleaning composition that comprises a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water, we see no reason to construe the term “cleaning composition” itself to require these components. Claim 1 expressly recites expressly including or precluding a chelating agent or a metal corrosion inhibitor. Ex. 1001, 29:2–9. The Federal Circuit advises that the specification “is not a suitable substitute for, nor can it be used to rewrite, the chosen claim language. ‘Specifications teach. Claims claim.’” SuperGuide, 358 F.3d at 875 (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 n. 14 (Fed. Cir. 1985) (en banc)). The ’329 patent specification does teach a cleaning composition that includes a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water, but claim 1 is directed to a cleaning composition that expressly requires only a subset of those components. Patent Owner’s proposed construction would effectively rewrite the claim by adding unclaimed components, which we decline to do under the guise of claim construction. See id.

“that Petitioner establishes that the ’329 patent does not provide sufficient written description support for the challenged claims. Pet. 15–43; Ex. 1007 ¶¶ 56–82. More specifically, we find that the ’329 patent does not reasonably convey to a POSA that the inventor was in possession of cleaning compositions that do not include a chelating agent or a metal corrosion inhibitor. There is no dispute, on this record, that the ’329 patent specification explicitly teaches that a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water are mandatory components of the cleaning composition described therein. PO Resp. 15 (Patent Owner agreeing with Petitioner that “[t]he ’329 patent’s disclosure is unambiguously explicit regarding mandatory components of the cleaning compositions described therein.” (citing Pet. 17; Ex. 1007 ¶¶ 56–57) (emphasis omitted, alteration in original)); see Ex. 1001, 3:47–48, 3:62–64, 10:24–26, 10:66–11:2, 12:3–4; Ex. 1007 ¶¶ 56–67. Claim 1, however, does not require that the cleaning composition include a chelating agent or a metal corrosion inhibitor. Ex. 1001, 29:2–9. Therefore, establishing proper written description support for claim 1 requires more than showing that the inventor was in possession of a cleaning composition that includes a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water; the ’329 patent must also show that the inventor was in possession of a cleaning composition that includes only a redox agent (hydroxylamine), an organic solvent (an alkylene glycol), water, and an alkanolamine.

“(2) Our analysis We agree with Patent Owner. Patent Owner’s plain reading of limitation 1(c) is correct, and under this reading, the combination of Shackle and Birrell fails to disclose or suggest limitation 1(c). Limitation 1(c) states in part: “at least one LED circuit having any number of LEDs . . . needed to approximately match the forward voltage drop of a first input voltage to the LED driver.” Ex. 1001, 27:22–25 (emphasis added). We have omitted the language “connected in series or series parallel” to highlight the grammatical relationship between the noun phrase “any number of LEDs” and the verb phrase “needed to approximately match.” The plain reading of this limitation is that the at least one LED circuit has any number of LEDs needed to approximately match the forward voltage drop of the LED driver input. Petitioner’s reading, that “the at least one LED circuit,” rather than “any number of LEDs,” must approximately match the forward voltage drop of the LED driver input, is strained and not grammatically plausible. See Reply 1–3. Petitioner does not assert there is an express disclaimer or disavowal in the specification that supports its position; Petitioner instead relies on examples disclosed in the specification to support its faulty interpretation of limitation 1(c). See Reply 2–3. These arguments are unpersuasive. It is axiomatic that we must not “limit[] the claimed invention to preferred embodiments or specific examples in the specification.” Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1346–47 (Fed. Cir. 2015). Not only that, but Petitioner’s citations to the specification better support Patent Owner’s position. In Petitioner’s view, the specification requires other non- LED components to be combined with one or more LEDs to “appropriately match the voltage.” Reply 2. The main example Petitioner relies on describes 38 LEDs having a total voltage drop of 114 V in a circuit with a bridge rectifier having a 6 V voltage drop. Id. at 2–3 (citing Ex. 1001, 16:64–17:7). Yet the 114 V voltage drop of the LEDs alone “approximately matches” the input voltage of 120 V, without the contribution of the bridge rectifier (6 V). Id. Indeed, 114 V out of 120 V is a 95% match. Thus, this example supports Patent Owner’s view that it is the voltage drop of the LEDs themselves, not the LED circuit as a whole, that must approximately match the LED driver input. See Sur-reply 6–7.” slip op. at 16

“combination. The first is that the proposed combination is not at all clear. Although Petitioner need not propose a bodily incorporation of different embodiments, Petitioner must provide a “reasoned analysis” explaining what the combination is. See DSS Tech. Mgmt., Inc. v. Apple Inc., 885 F.3d 1367, 1377 (Fed. Cir. 2018); In re Keller, 642 F.2d 413, 425 (CCPA 1981); see also Kinetic Concepts, Inc. v. Smith & Nephew, Inc., 688 F.3d 1342, 1368 (Fed. Cir. 2012) (“We must be careful not to allow hindsight reconstruction of references to reach the claimed invention without any explanation as to how or why the references would be combined to produce the claimed invention.”) (citation omitted). But the Petition never explains how or where Piepgras’s glass substrate would be combined with Piepgras’s alleged flexible substrate, the rope light of Figure 31. At most, Petitioner suggests incorporating the illumination device 500 of Figure 42 in the rope light of Figure 31. Pet. 48 (“Piepgras provides for configurations where a reflective platform (reflective substrate) mounts lighting system 500 in a manner applicable generally to the inventions of Piepgras . . ., and thus including the rope lighting application discussed above.”). As for the glass substrate, Petitioner merely states that “a POSITA would have found it predictable to configure the Shackle-Piepgras device to implement a flexible substrate mounted to the glass substrate, wherein at least one of the plurality of LED packages is mounted to the flexible substrate.” Id. (citing Ex. 1002 ¶ 150). This vague statement just parrots the claim language and does not explain anything about how the glass substrate would be included in the combination.” slip op. at 28
