      “structural connections and three-dimensional modeling Patent Owner’s experts attempt to make (see, e.g., Ex. 2070 ¶¶ 126–212, 297–342; Ex. 2068 ¶¶ 123–125, 245, 294–313, 318) do not appear in the written description itself. To the extent the experts disagree on this point, we credit the testimony of Petitioner’s experts over that of Patent Owner’s. See Ex. 1133 ¶¶ 111–230 (identifying problems with the approaches proposed by Patent Owner’s experts). For these reasons, we find that a preponderance of the evidence of record better supports a finding that in the 2011–2012 timeframe, it would have been unpredictable to identify which multiple mutants retained hyaluronidase activity, even with the single substitution data provided by the ’652 patent.” slip op. at 58

      “exclude the use of modified PH20 polypeptides as contraceptives—the only other possible utility described in the ’652 patent—is unavailing. Resp. 39. First, “[t]he fact that a patent asserts that an invention achieves several objectives does not require that each of the claims be construed as limited to structures that are capable of achieving all of the objectives.” Phillips, 415 F.3d at 1327 (citing Liebel–Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 908 (Fed. Cir. 2004)). Second, unlike the definitions of “PH20” and “modified PH20 polypeptide” in the “Definitions” section of the Specification, the passages describing possible contraceptive use do not contain any characteristics suggesting they are definitional in nature. See Alnylam, 138 F.4th at 133 (enumerating “characteristics” such as the fact that the text appears in the “Definitions” section, sets the term off in quotation marks, and uses phrases like “refer to” that indicate that specification language is definitional in nature). Accordingly, the statement that “[a]lso provided are modified PH20 polypeptides that are inactive, and that can be used, for example, as antigens in contraception vaccines” (Ex. 1001, 75:56–58), does not redefine the term, nor otherwise void the definitional language in the Specification stating that a “modified PH20 polypeptide can have up to 150 amino acid replacements, so long as the resulting modified PH20 polypeptide exhibits hyaluronidase activity.” Id. at 48:47–49 (emphasis added).” slip op. at 26

      “We find that a rigid requirement as to the subject of a POSITA’s doctoral degree (e.g., biochemical engineering, enzymology), or experience working specifically with horseshoe crab proteins, is not consistent with the evidence of record. See, e.g., Ex. 1067, 20:23–21:2 (Dr. Schaefer testifying that the fact the “name of [his] Ph.D. is immunology . . . does not change the fact that the core of [his] thesis training was really in molecular biology”), 22:3–15 (explaining that “the fact that the production of proteins recombinantly is mostly species agnostic”); Ex. 1069, 45:20–47:17 (Dr. Morris testifying that whether a person is a POSITA depends on the person’s “experience, [ ] publications,” and work done for the Ph.D. rather than the name of the Ph.D. program). We also find that evidence of record supports Petitioner’s assertion that, for purposes of defining a POSITA, “[m]ore education could substitute for experience, and vice versa.” See, e.g., Pet. 22; Ex. 1065, 99:14–100:3. Accordingly, based on the entirety of the trial record, we find a POSITA with respect to the claims of the ’109 patent would have had a two years of experience with cloning genes, expressing cloned genes as proteins, and/or characterizing such cloned genes and proteins, with more education being able to substitute for experience, and vice versa. A POSITA may also have collaborated with others, including those with specific experience in utilizing or assessing horseshoe crab Factor C for endotoxin detection and quantitation.” slip op. at 9

      “Neither party proposes an express construction of any claim term. See Pet. 22–23 (not proposing any constructions); PO Resp. 23 (“Patent Owner agrees that the terms can be afforded their plain and ordinary meaning.”). However, Patent Owner states that some of Petitioner’s arguments implicitly construe claim 1 in an erroneous manner. PO Resp. 23–28. “For example, Petitioner argues that ‘an adequate written description would have to either disclose representative examples of the possible working cascades of various proteins or some accurate structural feature of the claimed proteins that allow them to function in the claimed assay as a whole.’” Id. at 23 (quoting Pet. 35). Patent Owner argues that, contrary to what Petitioner’s argument allegedly implies, “Claim 1 is directed to a method for producing an endotoxin assay agent” and does not require the use – Owner that claim 1 does not require the use of endotoxin assay agent. However, the claimed endotoxin assay agent must be capable of performing the assay, as counsel for Patent Owner acknowledged. Tr. 83:5–9.” slip op. at 10

      “In this case, to show that the claims of the ’109 patent are unpatentable for lack of written description, Petitioner would have needed to show that the specification as filed (i.e., the ’420 application) fails to reasonably convey to those skilled in the art that Patent Owner had possession of the claimed subject matter as of the July 3, 2023, filing date. Petitioner did not. Pet. 23–24. Nor does Petitioner’s declarant offer testimony that could support such a showing. See Ex. 1003 ¶50 (“I have been asked to provide my opinions as to the state of the art in this field for purposes of determining what the inventors disclosed as their invention as of December 10, 2013.”), ¶51 (“Whenever I offer an opinion in this declaration about the knowledge of a POSA, the manner in which a POSA would have understood the claims of the ’109 patent or its description, the manner in have been led to do based on the prior art, I am referencing the December 10, 2013 timeframe.”). In our Institution Decision, we stated: Although the ’420 application is essentially identical to the ’767 application, the person of ordinary skill in 2013 is not the same as in 2023. See Ariad, 598 F.3d at 1351 (“[T]he [written description] test requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” (emphasis added)). Thus, the information presented in the Petition, which is limited to the perspective of a 2013 POSITA, does not demonstrate that it is more likely than not that at least 1 of the claims challenged in the Petition is unpatentable for lack of written description. Inst. Dec. 12 (alterations in original). During trial, Petitioner did not present any further arguments in support of Ground 1. See generally Pet. Reply. Petitioner has failed to prove that claims 1–9 are unpatentable for failing to meet the written description requirement set forth in 35 U.S.C. § 112(a).” slip op. at 12

      “Although the evidence before us shows that, in 2013, a POSITA knew how to recombinantly express genes in expression systems such as CHO or HEK-293 cell lines, the evidence shows that this was true only for genes whose genetic sequences were known or readily available. See, e.g., Ex. 1069, 34:11–22 (“Q. Okay. So you would agree that the creation of the recombinant protein requires the underlying sequence of, as you said, the original animal? A. Of course.”) Because it is undisputed that, in 2013, the genetic sequence for Limulus polyphemus Factor C was unknown, or least not publicly available, Falko-Gunter does not support a finding of adequate written description here.

      “overlap to a significant degree, i.e., a person with a Ph.D. in a discipline related to biological sciences and having had at least two years of work experience. However, the parties’ proposals differ slightly in the specific subjects in which a POSA would have had a doctoral degree, and whether the person’s work experience must have been directly related to horseshoe crab Factor C. As an initial matter, we find that a rigid requirement as to the subject of a POSA’s doctoral degree (e.g., biochemical engineering, enzymology), or experience working specifically with horseshoe crab proteins, is not consistent with the evidence of record.

      “Carrying Out the Invention section, that “[t]he Factor C of the present invention is a Factor C derived from a horseshoe crab,” and states later in the same section that “[e]xamples of the horseshoe crab include . . . Limulus polyphemus.” Ex. 1006, 40. However, none of the remaining portions of ’767 application cited by Patent Owner relate directly to L. polyphemus; instead, the remaining portions of ’767 application cited by Patent Owner are directed to other species, in particular the Japanese horseshoe crab T. tridentatus. Further, Patent Owner’s witness, Dr. Schaefer, conceded that the ’767 application does not contain Factor C sequence information for L. polyphemus. See, e.g., Ex. 1067, 44:25–45:23. Although “[n]o length requirement exists for a disclosure to adequately describe an invention,” Falko-Gunter, 448 F.3d at 1365–1366, we are persuaded that a POSA would not, based on the totality of the above disclosures, reasonably understand that the inventors were in possession of the claimed HEK-293 recombinant L. polyphemus Factor C protein, in view of the state of the art as of December 10, 2013. In this regard, we note that adequate written description of a biological molecule, such as a HEK293 recombinant L. polyphemus Factor C protein, requires “more than a mere statement that it is part of the invention and reference to a potential method for isolating it”; instead, what is required is “‘a precise definition, such as by structure, formula, chemical name, or physical properties,’ not a mere wish or plan for obtaining the claimed chemical invention.” The Regents of the” slip op. at 21

      “Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1364 (Fed. Cir. 2007). Neither do we see Petitioner’s arguments regarding the December 10, 2013 priority date to be “mutually opposed” as Dr. Schaefer testified. Ex. 1067, 216:4– 24. Instead, we credit evidence of record, including Dr. Jain’s testimony and the February 22, 2018 Mizumura Declaration, that existence of the full sequence would permit a more complete analysis and that such an analysis would provide a POSA with a reasonable expectation that the claimed L. polyphemus recombinant protein would have a residual activity within the claimed range. See, e.g., Ex. 1029, 2–5; Ex. 1010, 48; Ex. 1065, 117:14– 130:24 (explaining that comparison of partial sequences in the Tokunaga 1991 publication showed “difference around the cleavage site” between T. tridentatus and L. polyphemus but comparison of the full sequence revealed that “the catalytic triad of histidine, serine, aspartate . . . to be more similar between Tachypleus and Limulus”). Patent Owner asserts that “Petitioner’s reliance on a statement made by Dr. Mizumura in a declaration submitted during prosecution of the ’767 Application fails to fill the gap in the analysis” regarding reasonable expectation of success, because the declaration “offers no evidence of the percentage of conserved amino acid substitutions that exist to support the conclusion that a POSA would have expected residual activity to be maintained between Tachypleus tridentatus and Limulus polyphemus” PO Resp. 47. However, as noted above, Dr. Mizumura provides an alignment of Factor C proteins from the two different species of horseshoe crab, determines that the similarity between the amino acid sequence is 99.5%, states that the amino acid residues that can undergo N-type sugar chain that L. polyphemus, like T. tridentatus, would also be less susceptible to inhibition by ions. Ex. 1029, 4–5. For the reasons discussed above, we also disagree with Patent Owner’s assertion that Petitioner’s reasonable expectation of success argument is “nothing more than conclusory assertions with no support.” PO Resp. 46. Rather, we find Petitioner has shown, by a preponderance of the evidence, that a POSA would have had reason to combine the teachings of Mizumura and the ’498 PCT, with a reasonable expectation of success in arriving at the Factor C protein recited in claim 21.” slip op. at 38

Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention. In practice, the fact that the expert was not a person of ordinary skill at the time of the invention may well be used during cross examination to undermine the credibility of the expert.” Id. Under Petitioner’s proposed level of skill (which we adopted), Dr. McCulloh is indeed qualified to testify in this proceeding because he has a Ph.D. in Computer Science from Carnegie Mellon University and extensive experience, including “hands-on deployment and academic research in distributed systems operating under real-world constraints” (Ex. 2009, Ex. 2010). See Ex. 2010 (CV) (BSIE, MS Comp. Sci, PhD Comp. Sci, Lieutenant 1994-1999, 10th Mountain Division (“led the army’s first tactical deployment of a distributed computing system”)); Ex. 2009 ¶¶ 6–10.

      “Plain Meaning of “Substantially Real Time” Instead, the plain meaning of “substantially real time” is readily apparent and understood by a person of skill (POSITA) in the art in the context of data distribution or transmission of the ’128 patent as referring to an acceptable time delay (i.e., “a fraction of real time”) between distribution center 18 and user device 12, via network 14, shown in Figures 1–2 of the ’128 patent and, as such, is consistent with the ‘128 patent’s specification and Dr. Lippman’s Declaration (Ex. 1003, ¶¶ 79, 126). Because the plain meaning of “substantially real time” as understood by a POSITA is readily apparent, there is no reason for the Board to consider Patent Owner’s clarification of “substantially real time” based solely on extrinsic evidence, i.e., counsel argument, Mr. Johnson’s declaration (Ex. 2007, ¶¶ 27, 29–30, 33, 39; Ex. 1018, 38:13–39:20) and Dr. McCulloh’s declaration (Ex. 2009, ¶ 19). For example, Patent Owner, relying upon Mr. Johnson’s testimony, clarifies the term “substantially real time” requires either (1) “playback while transmission is ongoing” (PO Resp. 30), or (2) “[a] coordinated system behavior in response to a user’s request” “in which a user request triggers coordinated operations, including locating content across distributed systems, routing that content, and initiating playback while transmission is ongoing” (PO Sur-Reply 4 (citing Ex. 1001, 2:67–3:2, 6:23–35)). However, Patent Owner’s shifting position regarding “substantially real time” is not commensurate with the plain reading of the term. Based on the plain meaning of “substantially real time,” we are persuaded by Petitioner that Yurt explicitly discloses transmitting data at least in “real time,” preferably “less than real time” or “a fraction of real time” for playback.

According to Petitioner, because “Logan teaches implementation details for tracking user/usage data for billing purposes and adapting preferences ‘based on actual usage,’” “[a] POSITA would have thus been motivated to combine Yurt’s teachings (e.g., tracking information about requested items like item popularity) with Logan’s teachings (e.g., storing user data and usage information in response to user requests).” Id. at 19–20. “This would have been merely the use of a known technique (Logan’s tracking of user and usage data in response to user requests) to improve a similar method in the same way (Yurt’s tracking of information about user-requested items).” Id. at 20 (citing Ex. 1003, ¶¶ 67– 68). According to Petitioner, [T]he combination is straightforward: use Logan’s known technique for recording user data with Yurt’s existing item database teachings. See Ex. 1005, 12:28–57, 10:66–11:4; Ex. 1006, 5:33–42, 6:27–35, 8:49–58; Pet. 19–23. Since Yurt already teaches using its item database to track item popularity and request information, no modification to Yurt’s architecture is necessary. Logan merely confirms when and how to store the user information. Pet. 19–21. A POSITA would have found the combination obvious for all the reasons Dr. Lippman provided. See, e.g., Ex.1003, ¶¶ 71–72.” slip op. at 58

      “Under Petitioner’s proposed level of skill (which we adopted), Dr. McCulloh is indeed qualified to testify in this proceeding because he has a Ph.D. in Computer Science from Carnegie Mellon University and extensive experience, including “hands-on deployment and academic research in distributed systems operating under real-world constraints” (Ex. 2009, Ex. 2010). See Ex. 2010 (CV) (BSIE, MS Comp. Sci, PhD Comp. Sci, Lieutenant 1994-1999, 10th Mountain Division (“led the army’s first tactical deployment of a distributed computing system”)); Ex. 2009 ¶¶ 6–10. Although Dr. McCulloh’s declaration does not include any searching or analysis of patent literature including Yurt or Logan as part of his analysis of the “background” state of the art, as correctly recognized by Petitioner (Pet. Reply 7–8 (citing Ex. 1017, 74:18–75:14; Ex. 2009 ¶ 3)), we are persuaded that Dr. McCulloh is qualified to address Dr. Lippman’s portrayal of the architecture disclosed in the ’128 patent, as advanced by Patent Owner. Ex. 2009, ¶¶ 3, 5–34; Ex. 2010. Dr. McCulloh does not provide testimony to refute Petitioner’s obviousness analysis based on Yurt and Logan. See Ex. 2009. Mr. Johnson is only offered to refute Petitioner’s obviousness analysis based on Yurt and Logan. Ex. 2007 ¶¶ 3, 18, 29. Under Petitioner’s proposed level of skill (which we adopted), Mr. Johnson, who is a co-inventor of the ’128 patent, is qualified to testify in this proceeding, especially, when his declaration states that (1) he is a POSITA “with more than 30 years of experience building technology-driven media and contentdistribution systems” and (2) he “was actively involved in the development and deployment of digital music and video distribution technologies” since the mid-1990’s, including “real-time and near-real-time electronic delivery of media content.” Ex. 2007 ¶¶ 9–10, 14, 16. Certainly, “[t]he inventor himself may qualify as an expert and testify what his claims would mean in the relevant art.” Markman v. Westview Instruments, Inc., 52 F.3d 967, 991 (Fed. Cir. 1995). The fact that Johnson is a co-inventor is not in and of itself sufficient to discredit his testimony. “That an expert may have a bias or self-interest towards a party on whose behalf he or she is offering testimony, without more, generally does not require disqualifying the expert so long as the expert appears to be providing an objective analysis. Bias goes to the weight of the testimony, not necessarily its admissibility.” Apple, Inc. v. Motorola, Inc., 757 F. 3d 1286, 1321–22 (Fed. Cir. 2014). Nevertheless, the Board has broad discretion to assign weight to be accorded expert testimony. Yorkey v. Diab, 601 F.3d 1279, 1284 (Fed.

      “Based on the record before us, we determine that neither Patent Owner’s proposed clarification nor an express construction of “substantially real time” is necessary for our proceeding. Plain Meaning of “Substantially Real Time” Instead, the plain meaning of “substantially real time” is readily apparent and understood by a person of skill (POSITA) in the art in the context of data distribution or transmission of the ’128 patent as referring to an acceptable time delay (i.e., “a fraction of real time”) between distribution center 18 and user device 12, via network 14, shown in Figures 1–2 of the ’128 patent and, as such, is consistent with the ‘128 patent’s specification and Dr. Lippman’s Declaration (Ex. 1003, ¶¶ 79, 126). Because the plain meaning of “substantially real time” as understood by a POSITA is readily apparent, there is no reason for the Board to consider Patent Owner’s clarification of “substantially real time” based solely on extrinsic evidence, i.e., counsel argument, Mr. Johnson’s declaration (Ex. 2007, ¶¶ 27, 29–30, 33, 39; Ex. 1018, 38:13–39:20) and Dr. McCulloh’s declaration (Ex. 2009, ¶ 19). For example, Patent Owner, relying upon Mr. Johnson’s testimony, clarifies the term “substantially real time” requires either (1) “playback while transmission is ongoing” (PO Resp. 30), or (2) “[a] coordinated system behavior in response to a user’s request” “in which a user request triggers coordinated operations, including locating content across distributed systems, routing that content, and initiating playback while transmission is ongoing” (PO Sur-Reply 4 (citing Ex. 1001, 2:67–3:2, 6:23–35)).

      “We find unpersuasive Mr. Pollock’s testimony that we limit the level of ordinary skill to “refrigerated display cases” because defining the level of skill as an engineer with experience “working with refrigerated display cases” does not relate to the technology disclosed and claimed in the ’181 patent, which is controlling condensation and conserving energy. E.g., Ex. 1001, 2:17–21 (“The invention is proactive in preventing condensation temperature at frame and door surfaces is reached. Power is then cycled off at a set point above dew point to save energy.” (emphases added)). An electrical engineer with a bachelor’s degree and 2 years of experience focused on lighting systems for refrigerated display cases would have “experience working with refrigerated display cases,” and thus meet Patent Owner’s proposed level of skill. Such a person, however, would not be experienced in controlling condensation, dew point sensor positioning, and condensation algorithm design, which is the focus of the disclosed and claimed invention, and which Mr. Pollock states “materially affect performance, energy use, and reliability” in controlling condensation in a refrigerated display case. Ex. 2014 ¶ 11. We also note that Mr. Pollock’s qualifications are a “B.S. in Mechanical Engineering, cum laude, from Drexel University (1998), with focus on thermal and mechanical systems, thermodynamics, and HVAC&R (Heating, Ventilation, Air Conditioning & Refrigeration).” Ex. 2014 ¶ 3. Accordingly, based on the prior art, the sophistication of the disclosed technology in the ’181 patent, finding Mr. Pollock’s testimony on this issue too general, and crediting Dr. Henze’s testimony with substantial probative weight, we adopt Petitioner’s definition of the level of ordinary skill. We modify it to state that more academic training will offset less experience, and more experience will offset less academic training, as did Dr. Henze (Ex. 1003 ¶ 31). Thus, in this proceeding a person of ordinary skill would have a bachelor’s degree in mechanical engineering, electrical engineering, or a comparable field and at least three to five years of professional experience working with heating, ventilating, air conditioning, and refrigeration” slip op. at 16

      “The fundamental role of expert testimony is that “the expert’s scientific, technical, or other specialized knowledge will help the trier of fact [here, the Board] to understand the evidence or to determine a fact in issue.” Fed. R. Evid. 702(a). The testimony must be “based on sufficient facts or data” (id. at 702(b)); must be “the product of reliable principles and methods” (id. at 702(c)); and must reflect “a reliable application of the principles and methods to the facts of the case” (id. at 702(d)). We determine, based on the record before us, that Dr. Henze’s Declaration testimony meets these requirements. He provides, as required, the facts and data to support his testimony. Indeed, Federal Rule of Evidence 702 and the Code of Federal Regulations require him to do so. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Expert testimony that “merely repeats, verbatim, the conclusory assertion for which it is offered to support,” or that “does not cite to any additional supporting evidence or provide any technical reasoning to support” the testimony is entitled to little weight.

      “bears pointing out that the specification of the ’138 patent appears to explain what “a single allocation” means: If there are multiple QoS requirements within a single 3GPP PDP context, a single physical allocation of radio resources may be made to the UE. In this manner, a single PDP context implies a single CCTrCh. This single physical allocation of radio resources provided to a UE is shared amongst a number of services, in proportion to their respective QoS requirements, for example in proportion to the signalled weight values (Stier). Ex. 1001, 9:36–43 (emphasis added). Petitioner’s expert, Dr. Ding, explains that the “abbreviation CCTrCh was understood in the art to refer to a transport channel known as the Coded Composite Transport Channel.” Ex. 1003 ¶ 88. Dr. Ding testifies that Eckert teaches selecting data for uplink within a determined TTI and scheduling the uplink transmission on a transport channel, E-DCH, where scheduling of the E-DCH in a UE is controlled by a base station. Eckert, [0012] (“[A] new dedicated transport channel called Enhanced Dedicated Channel (E-DCH) has been introduced for this purpose. The fundamental characteristics of this new transport channel include . . . scheduling controlled by the base station, also called NodeB in UMTS…” Id. ¶ 90. In addition to Eckert disclosing a single transport channel E-DCH, Petitioner argues that Eckert discloses using a “finite quantum of physical resources” where “[t]he ’138 patent disclosure parallels Eckert, with both the E-DCH and CCTrCH transport channels relating to a UMTS uplink, employing spreading codes in code division multiple access (CDMA), and Reply 6 (citing Ex. 1005, ¶¶ 3, 8, 15, 23; Ex. 1071 ¶¶ 17–20; Ex. 1011 ¶¶ 6, 51).

      “We decline Patent Owner’s invitation to construe “during a frame” of “independently controlling simultaneous data acquisition with each of the first and second channels during a frame” by importing the extraneous limitations “at some point between the beginning and the end of the exposure interval during which the image sensors capture a single image.” As pointed out by Petitioner, Patent Owner’s proposed construction is unsupported by the language of claim 22 and the ’180 Specification because Specification does not disclose an exposure interval nor suggest “during a frame” is limited to an exposure interval. Patent Owner and its expert Dr. Saber cite only extrinsic evidence (Exs. 2006, 2009) to support its argument that claim 22 should be limited to an “exposure interval during which the image sensors capture a single image.” See PO Resp. 16–17; Ex. 2020 ¶ 64. Similarly, Patent Owner relies only on extrinsic evidence (e.g., Ex. 2011, 1; Ex. 2022, 1; Ex. 2020 ¶ 66) to limit “during” to “at some point between the beginning and the end.” See id. at 18. When considered in the context of claim 22 and the ’180 Patent Specification which do not limit “during a frame” to an exposure interval, we find that we cannot rely on Patent Owner’s citations to extrinsic evidence to yield a reliable construction for “during a frame.” As demonstrated in the analysis below, we need not provide an explicit construction for “during a frame” to resolve the parties’ disputes regarding the merits of the patentability challenges. See Realtime, 912 F.3d at 1375. We apply the ordinary and customary meaning for “during a frame.” To the extent that an explicit identification of the ordinary and customary meaning may aid the understanding of our analysis, consistent with the language of claim 22 and the ’180 Patent Specification, we find that the ordinary and customary meaning for “during a frame” is “during the period of time that data for an image frame is acquired.” See Ex. 1001, code (57), 20:6–24, 25:23–35.” slip op. at 12

See Dynamic Drinkware, 800 F.3d at 1379–1380. For a claim in a later-filed application to be entitled to the filing date of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed.

Patent Owner’s arguments fail to meet this burden of production because, aside from addressing deficiencies of written description support the ’854 Provisional Application provides written description support for all of the limitations of the claimed invention.

Specifically, Patent Owner does not address written description support in the ’854 Provisional Application for “independently controlling simultaneous data acquisition with each of the first and second channels during a frame”––limitation [22.3]––the heart of the parties’ claim construction disputes addressed above in Section II.A.

Accordingly, Patent Owner has not met its burden of production in coming forward with evidence or argument to show possession of the claimed invention in the ’854 Provisional Application.
