    “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. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . 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

Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

    “that Vyshedskiy’s disclosure of a list of preferred carrier frequencies represents a permissible “obvious to try” situation. In KSR, the Supreme Court stated that a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under § 103. KSR, 550 U.S. at 421. And simply because the prior art “discloses a multitude of effective combinations does not render any particular formulation less obvious.” Merck & Co. v. Biocraft Labs., Inc., 874 F.2d 804, 807 (Fed. Cir. 1989). The instant facts represent a situation where, at the time of invention in 2010, it would have been obvious to try the known carrier frequencies of Vyshedskiy for modulation of the acoustic ECG signal of Albert in the claimed frequency range of 6 kHz to 20 kHz because these carrier frequencies would have been obvious alternatives to try to address Vyshedskiy’s disclosed design need for simultaneous measurement of heart sound auscultation and ECG heart cycle.

    “The implicit premise of Patent Owner’s argument is that Brcka discloses only failures and thus does not disclose “fault detection.” However, we credit the testimony of Dr. Shanfield that “[g]enerally you always need a fault to have a failure occur. So when there is a failure, a fault has occurred.” Ex. 2003, 74:6–11; see also Ex. 1003 ¶ 37 (“A fault is an abnormal tool condition, such as when a parameter strays beyond its acceptable boundary. Faults may lead to failure, which is the ‘termination of the ability of an item to perform a required function.’”) (internal citation omitted), 81 (“Machine failure, though, means that a fault condition existed requiring termination of the machine function upon the wafer.”). Thus, Brcka’s disclosure of analyzing machine failures is also, necessarily, a disclosure of a analyzing a fault.

    “Petitioner cites to the embodiment depicted in Brcka’s Figure 4 as illustrating Brcka’s “fault detection analysis.” Pet. 32–33; see also Ex. 1003 ¶¶ 72–73. Figure 4 is a “flow diagram demonstrating operation of a learning system and [a] neural network model designed in accordance with at least one embodiment of [Brcka’s] invention.” Ex. 1005 ¶ 44. In step 415 of the operation disclosed in Figure 4, “a determination is made whether maintenance has been performed or a machine failure has occurred.” Id. ¶ 44, Fig. 4. If either of these things has happened, “a new reward value is calculated.” Id. In step 440, “a determination is made whether maintenance is needed.” Id. ¶ 45, Fig. 4. Thus, Brcka determines whether a failure has occurred, accounts for this determination by assigning a “reward value” (Fig. 4, step 425), and then decides whether maintenance is needed. On this record, the analysis reflected in these steps qualifies as a “fault detection analysis.” We recognize that Brcka’s fault detection analysis is used in a method that includes a predictive component. But, we do not find anything in the language of claim 1 that precludes performing the fault detection analysis as part of a predictive model. Indeed, the claim language requires only “performing . . . a fault detection analysis.” Moreover, the “fault detection” itself (i.e., Brcka’s step 415), as opposed to the analysis of the detected fault, is backward-looking, not predictive; it determines “whether . . . a machine failure has occurred.” Id. ¶ 44 (emphasis added).” slip op. at 16

    “Dr. Van Ness’s proposed POSA level is too broad. Under that proposal, an individual with, for example, an undergraduate degree in microbiology and three years’ work experience studying the habitats of bacteria might qualify as a POSA. It is not clear that such a person would have sufficient, relevant experience in the detection of chromosomal abnormalities, especially through non-invasive methods for detecting fetal 10 genetic abnormalities in maternal samples, as described in the ’720 patent. See, e.g., Ex. 1001, 1:22–5:44 (Field of Invention and Background Art). Petitioner’s proposal of the POSA level is more precise because it requires familiarity with techniques for detecting cell-free DNA in biological samples, which is relevant to the prior art and the claimed technology.

    “Owner relied not on properties unique to EDTA, but on the fact that it was a “well-known chelator” and anticoagulant: [T]he assertion by the Office that EDTA is a cell lysis inhibitor is simply incorrect. . . EDTA is not an “agent that inhibits cell lysis.” Rather, EDTA is a well-known chelator of calcium and magnesium. EDTA is routinely added to blood during the blood collection process as an anticoagulant due to its ability to chelate calcium. Ex. 2064, 1196. Given Patent Owner’s clear intent to exclude EDTA from the scope of the claimed “agent” on the basis that it was a chelator and an anticoagulant, we find that a POSA would have understood other chelators and anticoagulants to also be excluded from the scope of the claimed agent. Consistent with this understanding, during subsequent prosecution of the application that issued as the ’720 patent, Patent Owner argued that the Holodniy reference, which disclosed a method of detecting free nucleic acid in which blood was collected in tubes containing ACD, “fail[ed] to teach or suggest a method for detecting free nucleic acid comprising, inter alia, isolating free nucleic acid from a non-cellular fraction of a sample, wherein an agent that impedes cell lysis has been added.” Ex. 1003, 1428 (emphasis added). On the salient point here, the Examiner agreed, concluding that “Holodniy et al. teach a method of detecting free nucleic acid which comprises all of the limitations of Claim 1, except these authors do not teach that their samples comprise an agent that impedes cell lysis.” Id. at 1344 (emphasis added); see also id. at 1156 (finding that Adams et al., a reference that also collects blood in tubes containing ACD, taught “all of the limitations recited in Claim 1 except these authors do not teach adding an agent that impedes cell lysis to the sample.”). And Patent Owner argues 15 persuasively, without dispute from Petitioner, that ACD is the “only” addition to the collection tubes besides the blood sample itself. Sur-reply 4 (citing Ex. 1016, 2; Ex. 2023, 20:52–54). This supports that neither the Examiner nor the Patent Owner considered ACD as an anticoagulant chelator to be an “agent,” as that term is used in claim 1. Accordingly, we construe the phrase “agent that impedes cell lysis” to” slip op. at 15

    “function to prevent cell lysis, “by: (1) interacting with and stabilizing the cell membrane; (2) maintaining osmolarity so that the cells do not rupture; and (3) providing a nutrient source.” Reply 3 (citing Ex. 1002 ¶¶ 22–23; 2001 ¶ 169; Ex. 1059 ¶ 5; Ex. 1054, 125:3–127:12; 1057, 3–4, and Ex. 1056, 7– 13, 15–19, 24). Patent Owner argues that the evidence as to how dextrose functions to prevent cell lysis should have been presented in the Petition. Sur-reply 16. On this record, we do not agree. While this evidence could have been included in the Petition, it is responsive to arguments raised in Patent Owner’s response. See PO Resp. 18–22. In any event, consideration of this evidence simply explains how and why dextrose has the capacity to impede cell lysis, and we have already found that the ’720 patent provides 25 evidence that dextrose has this capacity. Under the circumstances, it was therefore reasonable for Petitioner, in the Petition, to rely on such disclosures of the patent itself. Further, consideration of how and why dextrose impedes cell lysis largely benefits Patent Owner, by providing reasons why dextrose might not inhibit cell lysis under the specific circumstance present in Lee.” slip op. at 25

    “interact with and stabilize the cell membrane. Reply 3 (citing Ex. 1002 ¶¶ 22–23). In the cited testimony, Dr. Edwards states, “it was known that carbohydrates have a role in membrane stabilization” and that dextrose “is a membrane stabilizer.” Ex. 1002 ¶¶ 22–23. This is consistent with the teaching in the ’720 patent that glucose is “[a]n agent that stabilizes cell membranes.” See e.g., Ex. 1001, 6:49–56. The evidence thus supports that dextrose can help to stabilize cell membranes. However, this evidence is tempered by evidence supporting that the “impact of carbohydrates on biological membranes is extremely complex” and that it is “extremely difficult to predict how solutes such as carbohydrates will affect biological membranes.” Ex. 2231, 60:18–61:2, 83:14–18 (Dr. Edwards testimony). This is because “there’s a finite but long – long list of variables that will impact the – the mechanism by which carbohydrate interacts with the cell membrane.” Id. at 66:20–67:7; see also id. at 66:1–15 (identifying temperature, concentration and pressure as variables that play a role in how carbohydrates interact with biological membranes); id. at 68:1–17 (identifying prior and simultaneous exposure to other substances as variables that play a role in how carbohydrates interact with biological membranes). 26 Petitioner also provides evidence that dextrose helps prevent cell lysis by “maintaining osmolarity so that cells do not rupture.” Reply 3 (citing Ex. 2001 ¶ 169; Ex. 1056, 7–13, 24; Ex. 1059 ¶ 5). We agree that the cited evidence supports that dextrose has the ability to prevent cell rupture by maintaining isotonicity. In particular, Rapoport found that erythrocytes in an acid-citrate glucose solution underwent osmotic hemolysis at a slower rate than erythrocytes in a simple citrate solution. Ex. 1056, 613. However, Patent Owner introduces evidence, which we credit, that the failure to maintain isotonicity does not necessarily cause cell lysis. Ex. 2299, 237:4– 16 (Dr. Edward’s testimony). For example, cells placed in a hypertonic solution may “shrink or kind of shrivel” rather than burst, and cells placed in a hypotonic solution may swell, but will not necessarily lyse.

    “For purposes of this Decision, we generally accept Petitioner’s proposed definition of the person of ordinary skill in the art (or ordinarily skilled artisan), which appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosures of the ’023 patent; however, we also agree with Patent Owner that such a definition should be flexible enough to include a person with a lesser academic degree and having experience working in the field, such as an engineer with clinical experience in ophthalmic surgery, as well as a medical doctor, such as an ophthalmic surgeon with experience working with medical optics and lasers. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (noting that the appropriate level of ordinary skill in the art may be reflected in “the prior art itself”) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). Such an expanded definition of the person of ordinary skill in the art, including aspects of both parties’ definitions, is appropriate based on our review of the record, which demonstrates individuals having a broad array of scientific degrees that collaborate as a team.

    “On this record, we agree with Patent Owner that the disputed preamble phrase is limiting. “[C]lear reliance on the preamble during prosecution to distinguish the claimed invention from the prior art transforms the preamble into a claim limitation because such reliance indicates use of the preamble to define, in part, the claimed invention.” Catalina Mkt’g Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808–09 (Fed. Cir. 2002). Here, the Examiner expressly allowed the claims in view of the Examiner’s Amendment changing “scanning system” to “cataract surgery scanning system,” thereby transforming this portion of the preamble into a limitation. Ex. 1006, 13, 15, 18; see Catalina Mkt’g, 289 F.3d. at 808. Furthermore, contrary to Petitioner’s arguments, the record appears to suggest that there are structural differences between the optical systems of cataract surgery systems on the one hand and corneal surgery systems on the other. See Ex. 2006, 5:30–36; Ex. 2009, 1209–10. Thus, on this record, we are not persuaded that the language added by the Examiner represents merely an intended use for the disclosed system. In view of the foregoing, for purposes of this Decision, we construe the preamble phrase “cataract surgery scanning system” recited in independent claims 1, 8, and 12 to be limiting.” slip op. at 10

    “The ’023 patent explains that a “cataract incision” is an incision created “to allow access for the lens removal instrumentation.” Ex. 1004, 10:17–19. The potential ambiguity in the claim comes, as Petitioner notes, from the fact that the cataract incision of claim 1 “only partially extend[s] through the target tissue,” which would not appear to provide immediate “access to an eye chamber of the patient’s eye.” Pet. 10; Ex. 1004, 10:19– 23, 14:15–21. Although somewhat ambiguous on its face, the prosecution history provides guidance as to how this claim phrase is to be interpreted. Phillips, 415 F.3d at 1317 (“Like the specification, the prosecution history provides evidence of how the PTO and the inventor understood the patent.”). During prosecution, the Applicants explained that the invention allows “straight cataract incisions [to be] made at the correct location,” and that partially penetrating cataract incisions are advantageous because they allow the laser delivery system to be located in an “unsterile field,” with the final penetrating incision to be made “by a physician after a patient has been moved to a sterile field.” Ex. 1006, 52–53. The Applicants then explained that despite the fact that partially penetrating cataract incisions do not fully for the lens removal instruments,” as that term is used in the ’023 patent. Id. at 52 (noting the purpose of “partially penetrating cataract incisions” is “to allow access for lens removal instruments”), 55 (“In short, none of the cited art teaches . . . to deliver the first treatment pattern to the target tissue to form partially penetrating cataract incisions – i.e. incisions that allow access for the lens removal instruments.”). The Examiner agreed with this reasoning. Id. at 15 (agreeing that the prior art did not teach or suggest partially penetrating cataract incisions that provide “access to the eye chamber of the patient’s eye”). Given these disclosures, we agree with Patent Owner that “provides access to an eye chamber of the patient’s eye” in claim 1 means that the partial incision is a starting incision, made in the appropriate shape and location, that allows complete access for lens removal instrumentation when completed, for example, by the surgeon. In view of the foregoing, we construe the claim phrase “cataract incision therein that provides access to an eye chamber of the patient’s eye, the incision . . . only partially extending through the target tissue” to require “a partially penetrating cataract incision that, when completed by the” slip op. at 12

    “We have considered the arguments presented by the parties and the evidence of record and conclude that Petitioner has the better position. The term “display screen,” as used in the challenged claims, refers to an intended use of the cleaning tool. As such, it does limit the scope of the claims. We begin by noting that the challenged claims are directed to a device or apparatus. Ex. 1002, col. 2, ll. 8–13. As such, the claims “cover what a device is, not what a device does.” Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1468 (1990). The preamble of both claims 6 and 11 read in part: “doll-like figure for cleaning or wiping the surface of a display screen.” Ex. 1001, col. 6, ll. 37–38; col. 7, ll. 1–2. Both claims end with the clause “providing a pliant cleaning tool for wiping a display screen.” Id. at col. 6, ll. 50–51; col. 7, ll. 13–14. These phrases are crafted in terms of a device for performing a specific function or use. This type of phrase has been found to recite an intended use and not a physical limitation. See Marrin v. Griffin, 599 F.3d 1290, 1294–96 (Fed. Cir. 2010). The recitation of the intended use in the body of the claim does not affect our analysis.

Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
