LG argues this proposed combination is merely combining prior art elements (i.e., Choi’s specific symbols representing external devices connected via input ports, with Kim’s EXTERNAL DEVICE card object 1380) according to known methods to yield the predictable result of “informing the user which external device is connected to an input port.” Id. at 45; see also id. at 14–15 (arguing the same).

    “highlighted when a user selects this content source in some manner. Ex. 1001, 30:27–51. At that juncture, after a user selects the content source and it is highlighted, the content source is then associated with the first content information, “801 – CNXN,” which is displayed on the right panel of Figure 15B. See id. We do not understand the ’040 patent as requiring the display “801 – CNXN” to cause the corresponding highlighting of Live TV 1504A as suggested by Multimedia. The claim language requires the two elements “being associated with”5 one another, but it does not require that one element’s display (first content information) causes the highlighting of the other element (content source). Our view is supported by the only description of highlighting a content source found in the specification of the ’040 patent. In regard to Figure 15B, the specification describes that “global panel 1404 may include one or more sources represented by icons and text, or shortcuts, 1504A-E.” Ex. 1001, 30:27–28. The specification describes how highlighting the source is user directed: Global panel 1404 may additionally indicate a source that is selected or highlight [sic] using indicator 1512; for example, indicator 1512 may comprise a box positioned around Live TV 5 As the Federal Circuit has explained, “the plain meaning of associating relates to a mere commonality.” Apple Inc. v. Motorola, Inc., 757 F.3d 1286, 1306 (Fed. Cir. 2014), overruled by Williamson v. Citrix Online, LLC, 792 F.3d 1339 (Fed. Cir. 2015) (on unrelated grounds). 801 CNXN. Although illustrated as a box, other methods or configurations which provide for icon selection and/or identification may be used. For example, instead of a box, indicator 1512 may comprise adjusting the background of an icon and text, such as 1504A for example, such that the color, shade, or hue is different. Id. at 30:41–49 (emphasis added). Highlighting, as the specification describes, occurs when a user selects a source using indicator 1512 and that source is boxed or differentiated by color or shading. Id. The specification, in relation to Figure 15C, further describes a user moving indicator 1512 to another source such that the “the content or a preview of the content may be displayed in active content area 1408.” Id. at 32:9–17 (“For example, FIG. 15C illustrates an image or video associated with Skyfalls being displayed in content area 1408.”). Thus, the specification is clear that the highlighting function results from user selection of the source and the corresponding association of the first content information with that source flows from that user selection. See also id. at 2:30–31 (describing a purpose of the ’040 patent as “an Intelligent TV with intuitive user interfaces and with seamless user interaction capability”), 32:35–43 (“[t]he user . . . move[s] the focus box”).

    “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage.

    “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed.

Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

The claim is inartfully written, as it requires the LEDs to comprise a phosphor coating but then separately recites that the LED chips and the phosphor coating are formed or mounted to the substrate. But Petitioner correctly explains that the plain meaning requires that “the LED chips comprise a phosphor coating” and that “the [same] phosphor coating” (included in the LED chips) is “formed or mounted to a flexible substrate.” Reply 2. In other words, the use of the term “the” before “phosphor coating” indicates reliance on the antecedent basis of “LED chips comprise a phosphor coating,” and thus the same coating of the LED chips is formed or mounted to the substrate. Logically, by including a phosphor coating with the LED chips, which are formed or mounted to the substrate, the coating of these chips is also indirectly formed or mounted to the substrate. Conversely, it would be illogical to conclude that the claim recites two phosphor coatings, one attached to the LED chips and another attached directly to the substrate, because the structure of the claim refers to a single phosphor coating of the LED chips. Even Patent Owner concedes that the claim encompasses the phosphor coating indirectly being mounted or attached to the substrate (in addition to being directly attached).

    “After considering Patent Owner’s arguments, which we address below, we agree with Petitioner that the combination of Wojnarowski and Martin discloses this limitation and that a person of ordinary skill in the art would have been motivated to combine the references’ teachings in the manner asserted by Petitioner. Briefly, we summarize our findings, and then we address the parties’ arguments in more detail. First, we agree with Petitioner, and Patent Owner does not dispute, that Wojnarowski’s AC input voltage would have been converted to DC voltage in light of the bridge rectifier and capacitor disclosed by Wojnarowski. Pet. 25; Ex. 1002 ¶¶ 119– 20 (citing, e.g., Ex. 1005, 7:59–62, Fig. 24); PO Resp. 35–36 (acknowledging Wojnarowski discloses converting an AC input to a DC voltage). Second, we further agree with Petitioner, and Patent Owner does not dispute, that excessive current due to too few LEDs would have harmed Wojnarowski’s LEDs, and too small a current due to too many LEDs would be insufficient to power Wojnarowski’s LEDs. Pet. 26; Ex. 1002 ¶ 134; PO Resp. 48 (discussing, but not disputing, these assertions).13 Third, we agree that a POSITA would have recognized in view of Martin’s teachings and the knowledge of a skilled artisan that when configuring Wojnarowski’s device, the total forward voltage drop of the series-connected LEDs should approximately match the DC voltage output 13 Petitioner explains the relationship between voltage and current for the LEDs as follows: “the total voltage drop of the circuit would dictate the current drawn by the LED circuitry, which would have been known to be inversely proportional to the voltage.” Pet. 26 (citing Ex. 1002 ¶ 134). of Wojnarowski’s circuit. Pet. 26–27 (citing Ex. 1002 ¶¶ 132–38; Ex. 1008, Abstract (LED voltage “must be matched to the input source voltage”), ¶ 60 (“For AC or any other regularly varying input voltage, there is an additional requirement to direct drive voltage matching”)). For example, Martin teaches that “[t]he number of LEDs in the monolithic array may be selected to achieve a particular voltage drop across each device.” Ex. 1006 ¶ 22. Martin further explains, “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series,” and “[t]he number of LEDs is chosen such that the maximum voltage across each individual LED during the peak in the alternating current cycle is low enough so as not to damage the LEDs.” Id. The forward voltage drop across Martin’s 38 LEDs is about 171 V, which matches Martin’s AC input voltage peak of about 169.71 V. See id. (“At 120 RMS volts, the peak voltage will be about 180V [correction: 169.71 V],” and if the LEDs “can tolerate a maximum forward voltage of 4.5V, at least 38 LEDs connected in series are required.” (38 LEDs x 4.5 V = 171 V)); PO Resp. 41–42 (“While Martin references ‘about 180V,’ both parties agree that the correct value of the peak voltage Vp is 169.71 V.” (citing Ex. 1002 ¶ 127)). Although Martin’s LED forward voltage drop (171 V) differs slightly from the peak input voltage (169.71 V), Patent Owner conceded at the hearing that the claimed “matches” does not require an exact equivalence. Tr. 38:9–11 (“Patent Owner agrees . . . that matching has a meaning that goes beyond exact equivalence.”).14” slip op. at 22

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

    “35 U.S.C. § 311(b). PO Resp. 22–25. This statute provides that “[a] petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” § 311(b) (emphasis added). Patent Owner contends that Martin is not available as prior art under 35 U.S.C. § 311(b) because it is not a patent or printed publication and is only prior art under 35 U.S.C. § 102(e). PO Resp. 22. Patent Owner argues that documents are “printed publications” as of the date they become available to the public, and Martin became public on its publication date of October 21, 2004, after the February 25, 2004 priority date of the ’979 patent. Id. at 23. Patent Owner raises a similar argument for the Soules-II reference in Ground 6. Id. at 25– 26. Petitioner responds that the AIA framework permits the use of § 102(e) prior art in IPR proceedings, unlike formerly available covered business method review (CBM) proceedings, which restricted challenges to § 102(a) prior art. Reply 29. We agree. The statute governing the formerlyavailable CBM proceeding explicitly limits challenges based on “prior art that is described by section 102(a).” AIA § 18(a)(1)(C). In contrast, § 311(b) more broadly permits challenges “on the basis of prior art consisting of patents or printed publications.” The broader language in § 311(b) implies that unlike CBMs, IPRs are not limited to challenges solely under § 102(a) prior art. The parties cite to no Federal Circuit decisions that squarely address this issue. However, the Federal Circuit has applied § 102(e) patent application publication prior art in appeals from IPR proceedings. See, e.g., Purdue Pharma L.P. v. Iancu, 767 Fed. App’x 918, 920–21, 926 (Fed. Cir. 2019) (nonprecedential) (determining that a § 102(e) patent application publication was available as prior art in an IPR). The Board has also long permitted challenges based on patent application publications under § 102(e). See, e.g., Idle Free Sys., Inc. v. Bergstrom, Inc., IPR2012-00027, Paper 14 at 27 (PTAB Jan. 31, 2013) (instituting trial over § 102(e) ground based on a patent application publication). We therefore find Patent Owner’s § 311(b) argument unpersuasive.” slip op. at 34

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

    “B. CLAIM CONSTRUCTION Petitioner and Patent Owner offer different constructions for a single claim term—“penetrating.” See PO Resp. 19; Pet. Reply 1. However, the parties’ differing constructions do not impact our unpatentability analysis. Therefore, we decline to construe this term. We find no claim terms require express construction to determine unpatentability. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Matal, 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am.

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

    “Rather, as explained above, Petitioner relies on the top portion of Torii’s electrode 13 as the claimed source electrode, and the bottom portions as the claimed conductive portions. That is, even if Patent Owner is correct that the claimed source electrode and conductive portions must be distinct structures, that does not undermine Torii’s disclosure because Petitioner relies on distinct portions of Torii’s larger, single-hashed element labeled electrode 13. Because Petitioner does not rely on the same structure, i.e., the entire electrode 13 of Torii, for each of two distinct claim elements, our conclusion does not conflict with the Federal Circuit’s holding in Becton. See Becton, 616 F.3d at 1254 (holding that a single hinge structure could not be both the claimed spring means and the claimed separate hinged arm); id. at 1255 (noting that “[i]f the hinged arm and the spring means are one and the same, then the hinged arm must be ‘connected to’ itself,” which is “a physical impossibility”) (emphasis added). Instead, we agree with Petitioner that this case is more analogous to Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1231–32 (Fed. Cir. 2011), where the court held the front half of a cutting box satisfied a “cutting box” limitation, and its rear half satisfied a separate “dust collection structure” limitation. See id.; Pet. Reply 3. Like Powell, which “divided the cutting box” into two portions that each met a single claim limitation, Petitioner argues that one portion of Torii’s electrode 13 (the top portion, colored red by Petitioner) discloses the source electrode, and the remaining portions of Torii’s electrode 13 (the bottom portions, colored pink by Petitioner) discloses the conductive portions. See Powell, 663 F.3d at 1231. In Powell, the claim required “[the] cutting box interior [to be] in fluid communication with [the] dust collection structure,” and the court found that this requirement did not require that the two elements “be wholly separate structures.” Id. at 1229, 1231–32. Similarly, we determine that the requirement that the source electrode and conductive portions are electrically connected does not require that these be wholly separate structures. For these reasons, we agree with Petitioner that together, the top portion of Torii’s electrode 13 discloses the source electrode and the bottom portions of Torii’s electrode 13 disclose the conductive portions recited in claim 4.” slip op. at 14

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundUnpatentable

    “We agree with Petitioner that Hebinuma teaches the oval trenches recited in claim 6. See Ex. 1027, Fig. 9. In addition, we agree that Petitioner’s proposed combination would have been obvious because it amounts to no more than a simple substitution of one known element for another, i.e., Hebinuma’s elliptical trenches for Torii’s rectangular ones. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). Thus, with the analysis outlined above, Petitioner has articulated sufficient reasoning with rational underpinning to support the legal conclusion that its proffered combination would have been obvious to one skilled in the art. See id. at 418. Patent Owner raises several arguments in contesting Petitioner’s obviousness challenge, none of which we find persuasive. For example, we disagree with Patent Owner that Torii and Hebinuma are not analogous art because a skilled artisan “would not have looked to Hebinuma to improve on Torii.” PO Resp. 72–76. The ’867 patent, Torii, and Hebinuma are all in the same field of “power semiconductor device[s] having a trench gate structure.” Ex. 1001, 1:5–8; Ex. 1027 ¶¶ 1–3; Ex. 1030 ¶¶ 1–4. Thus, Torii and Hebinuma are analogous to the ’867 patent. See In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004). We also disagree with Patent Owner’s argument that one skilled in the art would not have had a reasonable expectation of success because Hebinuma’s oval-shaped trenches were “substantially more challenging” than Torii’s “well-known and well-studied” rectangular-trench solution. PO Resp. 77 (citing Ex. 2013 ¶¶ 128–130). Instead, we agree with Petitioner that one skilled in the art could reasonably expect success because the change “requires only minor changes to the photolithography mask” (Pet. 72; see Ex. 1002 ¶ 364), and because both Torii and Hebinuma expressly teach different trench shapes (see Ex. 1030 ¶ 116 (teaching that “the corner portion of the aperture . . . may be rounded”); Ex. 1027 ¶ 49 (teaching that “the contact trench Tc can be formed under similar conditions . . . with the exception of changing the patterning shape”)).” slip op. at 17
