  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Petitioner contends: A person of ordinary skill in the art (“POSA”) at the time of the alleged invention of the ’223 patent would have had a university degree in chemistry and additional expertise or a second university degree in the field of electrical engineering, particularly optoelectronics, or alternatively a university degree in electrical engineering and additional expertise or a second university degree in the field of chemistry. The person of ordinary skill in the art has spent several years studying the structure and function of organic optoelectronic components, in particular OLEDs, and has detailed knowledge of the chemical structure of light-emitting organic layers and the transport of charge carriers to these layers. In this respect, the person of ordinary skill in the art works at the interface between electrical engineering/physics (charge carrier transport and light emission processes in optoelectronic components) and chemistry, in particular organic chemistry (materials and layer stack combinations suitable). Pet. 14 (citing Ex. 1003 ¶¶ 46–47). Patent Owner does not dispute Petitioner’s contention. See generally Resp. Neither party indicates that the result would change depending on the definition selected. We adopt Petitioner’s uncontested proposed definition, because it is consistent with the disclosures of the asserted prior art references.

    “history pertaining to the patent.” 37 C.F.R. § 42.100(b). Under that standard, claim terms generally are given their plain and ordinary meaning as would have been understood by the ordinarily skilled artisan at the time of the invention and within the context of the entire patent disclosure. See Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). We construe claim terms only as relevant to the parties’ contentions and only to the extent necessary to resolve the issues in dispute. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999); Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017). Neither party indicates that an express construction for any claim term is necessary to resolve the disputes at hand. Pet. 15; see generally Resp. On this record, we determine that no claim term requires express construction for purposes of this Decision. In our analysis of the challenges, however, we discuss the meaning of the terms “metal complex” and “central metal atom,” which appear in claim 1 (Ex. 1001, 19:19–20) to the extent necessary to resolve Patent Owner’s contention that Petitioner fails to establish that Ma invalidates claim 1.

    “Based on the information presented, we find Petitioner has the better position. Patent Owner admits that joint vaporization means “two materials vaporize together.” Reply 21 (quoting Resp. 54). As Petitioner argues, “This is what Ma discloses.” Id. We agree with Petitioner that Ma describes a “two-component” electron transport layer having a “thickness with one value.” Id.; see Ex. 1007, 811 (reporting a “co-deposited” application of “BPhen:LiQ” that is “50 nm thick”). Ma’s disclosure, thereby, strongly “indicates that the two components were vaporized together––as opposed to creating a ‘macroscopically homogenous form’” prepared by sequentially vaporizing the individual components as Patent Owner “hypothesizes.” Reply 21 (citing Ex. 1020 ¶¶ 42–44; Ex. 2041 ¶¶ 155–157); see Resp. 54– 55; see also Ex. 1007, 811 (Ma’s description of its device fabrication, appearing in the third paragraph of the experiments section). Petitioner further advances evidence that “[p]reparing a layer that is ‘macroscopically homogeneous’ but potentially microscopically heterogeneous,” as Patent Owner postulates, “would introduce excessive variability and render the data noncomparable and unreliable, thus undermining the experiment’s purpose.” Reply 21 (citing Ex. 1020 ¶ 44); see Resp. 54–55. Patent Owner presents no counterargument or evidence that is persuasive to undercut Petitioner’s reasoning or evidence on that point. See Sur-reply 19–22. Petitioner also argues that an ordinarily skilled artisan would have recognized “that vaporizing materials together would best achieve Ma’s objective of assessing the current density using different Liq doping percentages.” Reply 22 (citing Ex. 1007, 811; Ex. 1020 ¶ 51). Here again, Petitioner’s evidence on point stands uncontested. See Sur-reply 19–22 (declining to contest that point). On this record, therefore, we agree with Petitioner that, as to the relevant disclosure in Ma, “the most natural interpretation of ‘co-deposition’ for forming a layer, particularly when there is nothing to indicate that the materials” are “vaporized sequentially,” is that the materials are co-deposited by joint vaporization. Reply 22 (citing Ex. 1020 ¶ 46–51). We further agree that, “[u]nder a preponderance standard, Ma’s disclosures are sufficient to render joint vaporization at least obvious.” Id. For the above reasons, we determine that Petitioner demonstrates by a preponderance of the evidence that Ma discloses joint vaporization as required by the challenged claims.” slip op. at 15

    “declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 18 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52, EPRC 1:32. One requirement of this apparatus is that it comprise “a semiconductor chip” (id. at 9:66) where “said semiconductor chip is a light emitting diode (LED) chip EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction (Resp. 14) of “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor LED chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 53 (quoting Ex. 1008, 10). Notably, claim 18 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim.

Patent Owner’s description appears consistent with the prior art and patent specification before us and is supported by witness testimony. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Petitioner responds that the phrase “needs no construction” and that Petitioner’s grounds meet this construction. Reply 1. We note that the language of claim 18 does not precisely match the language the District Court considered, it is substantively the same. The record supports a construction very similar to the construction the District Court adopts, and we reference the District Court’s reasoning. Ex. 1024, 15– 18. We, thus, construe claim 18’s recitation that “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip that is capable of emitting light greater than about 40 milliwatts.” It is unnecessary to construe any other claim terms in this Decision because none of the parties’ disputes turn on the meaning of other terms.

    “The facts above are evidence of the Krames reference’s publication as of June 29, 2000, because the facts tend to make the Krames reference’s publication as of June 29, 2000, more probable than it would be without the evidence. See Fed. R. Evid. 401(a) (defining evidence as relevant “if it has any tendency to make a fact more or less probable than it would be without the evidence”). The evidence is sufficient to support publication. Meanwhile, no evidence of record suggests that Krames was not a printed publication as of June 29, 2000. Thus, a preponderance of the evidence supports Krames’s prior art status. Patent Owner argues that Ms. Watters “never establishes a firm date when Krames was purportedly available to the relevant public.” Resp. 21. Patent Owner bases this argument by taking a tortured reading of Ms. Watters’s statement that “[m]embers of the interested public could locate a copy of [the Proceedings] on or after June 29, 2000, the date it was catalogued.” Id. (quoting Ex. 1020, 3); see also Sur-Reply 12–13. The best understanding of Ms. Watters’s statement, in view of the context of Ms. Watters explaining the library’s cataloguing process, is that a member of the interested public had two options: the person could choose to locate the Proceedings on June 29, 2000, or the person could choose to locate the Proceedings after June 29, 2000.

    “In the Reply, Petitioner uses the Krames declaration (Ex. 1028) to argue, for example, that a person of ordinary skill in the art would have used a lower amperage than the 1.5 A dc that Patent Owner’s Response focuses on. Reply 8 (citing Ex. 1028 ¶ 22). This use of the Krames declaration is timely because it responds to an argument Patent Owner makes in the Patent Owner Response. 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in . . . patent owner response.”). As to relevancy and whether the Krames declaration is applicable to the facts of this case, the issues at hand are (1) whether or not a person having ordinary skill would have had reason to use the Krames LED with Begemann with a reasonable expectation of success and (2) whether or not the Krames LED is capable of outputting light at greater than about 40 milliwatts. Again, we emphasize that claim 21 does not recite a method where the LED within the recited semiconductor light source actually outputs greater than about 40 milliwatts. The Krames declaration is relevant to the facts of this case because the declaration has bearing on whether or not a person of ordinary skill in the art would have combined the Krames reference’s LED with Begemann’s lightbulb design. See, e.g., Ex. 1028 ¶ 22. Patent Owner argues that evidence must be relevant to motivation to combine “an LED chip from the Krames article (operating at 1.5 amps to produce 170 milliwatts of output)” but claim 21 has no “operating at 1.5 amps to produce 170 milliwatts of output” requirement. What is relevant is that Krames discloses a single chip that has the capability of outputting more or less light depending on operating conditions. Pet. Opp. 3; see also Ex. 1008, 8 (providing that Figure 12 of the Krames reference is described as illustrating “[l]ight output vs. current characteristic of a blue … 1x1 mm2 AlGaInN LED in a power package, compared to a conventional AlGaInN LED in a 5 mm lamp a package”). Because claim 21 does not require actually running the recited LED at any particular wattage or amperage, it is appropriate for the Krames declaration to rebut Patent Owner’s argument that a person of ordinary skill would not have considered using the Krames LED with Begemann at high amperage by explaining that a person of ordinary skill in the art would have considered using the exact same Krames LED with Begemann at a low amperage instead and that at this lower amperage the Krames LED would generate an amount of heat that would be easily dissipated by Begemann’s lamp while still providing an optical output of “greater than about 40 milliwatts” as recited by claim 21. Ex. 1028 ¶¶ 23–24 (citing Ex. 1008, 8). The fact that the Krames LED is configured to run at the high amperage if desired for a different application does not negate the rationale for combining the Krames LED to run at a lower amperage.” slip op. at 14

Pet. 54 (quoting Ex. 1008, 10). Notably, claim 21 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim.

Patent Owner is correct that Petitioner primarily relies on Example 1 as evidence for the method by which its scaffold is made. But the disclosure found in paragraph 98 is not a “distinct” teaching of the type described in Net MoneyIN; rather, it is a general description of the structures that may be created by Johnson’s method: “A scaffold may comprise any number of layers, including about 1 layer, about 2 layers, about 3 layers, about 4 layers, about 5 layers, and so on.” Ex. 1009 ¶ 98.

A petition must include “[a] full statement of the reasons for the relief requested, including a detailed explanation of the significance of the evidence including material facts, and the governing law, rules, and precedent.” 37 C.F.R. § 42.22(a)(2).

We are persuaded that the Petition’s claim 32 arguments, in which Yeh was combined with Lin for an obviousness argument, adequately put Patent Owner on notice of Petitioner’s arguments that Lin’s third dispersing method—stirring—could be another dispersing method in Petitioner’s anticipation argument for claim 1 based on Lin. Here, Lin is the only prior art upon which Petitioner bases its anticipation argument, and Lin identifies a third dispersing method in close textual proximity to the identification of the first two dispersing methods. Ex. 1002, 37 (listing stirring on the same page, in the same paragraph, and only four lines after discussing ultrasonication). Patent Owner was made aware of this third dispersing method in Petitioner’s case-in-chief, albeit regarding a different claim. Under the particular circumstances presented here, we are persuaded that the disclosure in Lin, relating to the stirring step, was fairly raised in the Petition and that Patent Owner was given a fair opportunity to address its import in this proceeding.” slip op. at 10

    “It is not disputed that the cited portion of Lin discloses two dispersing steps that occur at discrete points in time. It is disputed whether these two discrete dispersing steps are different dispersing steps. The second dispersing method involves application of an ultrasonic probe to the Al2O3 suspension. Ex. 1002, 36–37. At that point, an Al2O3 suspension is already created. Although Lin’s first dispersing method is not named, it requires that “Al2O3 powder was dispersed in deionizied water” such that a “dilute dispersed aqueous suspension of 2 vol% solid concentration was prepared.” Id. at 37. Thus, in Lin’s first dispersing method, Al2O3 powder is introduced to liquid to create a dilute dispersed aqueous solution. Our construction of dispersing method encompasses “methods that cause α-Al2O3 powder to become or continue being distributed throughout an aqueous solution.” Certain Examples of the ’584 patent provide that the powders “were introduced” as part of the first dispersing step. Ex. 1001, 11:39–40, 12:63, 14:3. Introducing dry powder to liquid is a method that causes the powder to become distributed throughout an aqueous solution. This is a dispersing method that is different than ultrasonication. Even if powder were introduced to liquid, and ultrasonicated at the same time, this still is a “different” dispersing method than ultrasonication alone by virtue of the introduction to liquid step. Thus, Lin discloses two different dispersing methods.” slip op. at 9

    “The evidence supports a conclusion that the broadest reasonable interpretation of the term “moisture” is liquid water—that is, a condition of 100% relative humidity. The written description uses the term “moisture” in a context that suggests liquid water. See, e.g., Ex. 1001, 28:65-67 (applying a “wax/water slurry” to surface of sample film in order “to retain moisture”); 35:17-18 (applying heat to remove “moisture” from samples, suggesting removal of liquid water). Moreover, where the written description discusses water in vapor form, the inventors use the word “humidity” or “atmospheric moisture,” but not “moisture” alone. See, e.g., id. at 21:47 (referring to “atmospheric moisture”); 28:48, 60, 65 (referring to “humidity”). The ’189 patent further discloses that a “ribbon assembly can be buried under ground or water for long distance connections, such as between cities,” which is consistent with the proposition that an optical fiber coating must endure long periods of immersion in liquid water without delaminating. Ex. 1001, 67:43-45. In light of the context in which the term “moisture” appears in the specification, we conclude that the inventors used that term in its ordinary sense to refer to liquid water. The ’189 patent, thus, is directed to a coating composition that, after radiation cure, has sufficient adhesion to glass to prevent delamination in the presence of liquid water. We decline to resolve what temperature, or length of time of exposure to liquid water the coating must endure, without delaminating, in order to satisfy the claimed adhesion property. Resolving those conditions is not necessary to our analysis, which focuses on whether Corning’s wet adhesion test, conducted under conditions of 95% relative humidity, is probative of the extent to which a cured coating delaminates from glass when exposed to liquid water.” slip op. at 10

    “We do not agree with Corning that the ’189 patent defines the term “stripping temperature” as “about 90°C to about 120°C.” Rather, the patent indicates that stripping temperature is “typically” within this range. Ex. 1001, 13:32-34; accord id. at 14:21-25 (“[F]or most coating compositions the design ribbon stripping temperatures are usually about 90° C. to about 120° C., but may be different depending on the specific design parameters for the particular coating composition.”). This disclosure is too imprecise to serve as a definition. See Paulsen, 30 F.3d at 1480. The ’189 patent does refer repeatedly, however, to 90°C as an exemplary stripping temperature. E.g., Ex. 1001, 31:14-15, 31:41-42, 50:55. The ’189 patent also identifies 100°C as an exemplary stripping temperature, particularly in the context of measuring change in length. Id. at 14:46-47, 18:44-45. Whatever other temperatures this term encompasses, it certainly encompasses at least the ones specifically identified. See Oatey Co. v. IPS Corp., 514 F.3d 1271, 1276 (Fed.

    “plots is whether they exhibit a linear region of negative slope. Corning argues that they do, and the description in Exhibit 2015 that a region of the Shustack Example I plot showing a “linear relationship” was used to calculate slope bears out this argument. See Ex. 2015, 1. DSM, in contrast, argues that Corning’s plots lack “a substantially smooth linear region” but offers little evidence to support this assertion beyond Dr. Taylor’s statements that the plots “have no linear region from which to measure a slope” and that they lack any “substantial linear region.” See Resp. 31; Ex. 2032 ¶ 86. Dr. Taylor gives no credible explanation for the basis on which he reaches these conclusions. Even if Dr. Taylor provided some underlying facts or data for this conclusion, Dr. Taylor’s statements do not support DSM’s argument that there is no substantially smooth linear region. As between the conflicting evidence on this point, we credit Corning’s evidence, particularly from Exhibit 2015, in which Corning’s Mr. Gleason identifies the region of linear relationship as extending between displacements of 2.76 mm and 7 mm. DSM does not explain why this determination is invalid. We agree with Corning that the plots for Shustack Example I show a linear region of negative slope from 2.76 mm to 7 mm.

(“If the record on review contains not only all evidence which was clearly admissible, but also all evidence of doubtful admissibility, the court which is called upon to review the case can usually make an end of it, whereas if evidence was excluded which that court regards as having been admissible, a new trial or rehearing cannot be avoided.”).” slip op. at 19

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
