    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “We agree with Petitioner and determine that a POSA would have been a person having a general knowledge about, and experience with, expandable containers, including, without limitation, balloons, and at least an associate’s degree in mechanical engineering, or the equivalent. This level of skill is consistent with the types of problems and solutions described in the ’612 patent and cited prior art. For example, the ’612 patent describes a fluid inflatable system that uses elastic valve 20A (e.g., mechanical gasket, O-ring, etc.) for sealing fluid inside multiple containers (e.g., water balloons). See Ex. 1001, 1:22–24, 3:10–16. In any event, none of the issues in this case turn on the definition of a POSA, and the prior art of record provides ample evidence of the level of skill in the art. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (finding that the Board of Patent Appeals and Interferences did not err in concluding that the level of ordinary skill was best determined by the references of record); see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“[T]he absence of specific findings on the level of skill in the art does not give rise to reversible error ‘where the prior art itself reflects an appropriate level and a need for testimony is not shown”’) (internal citation omitted).” slip op. at 13

    • Disclosure Requirements (§112) › Definiteness (Nautilus)IndefiniteNot shown unpatentable

      “While the terms “unfilled state” and “filled state” describe the fullness for a container, we do not agree with Petitioner that the claim language requires determining the precise amount of fluid for each state. Section 112(b) requires that we read claim terms in the context of the surrounding claim language, not in isolation. Telebrands, 733 F. App’x at 1020. When we look at the entire claim phrase—“regardless whether the first and second ones of the plurality of containers are in a filled state or an unfilled state”— the plain language is clear that regardless of whether the balloons are in either state, the “at least first and second ones of the plurality of containers are disposed sufficiently close to each other such that they press against each other.” In other words, the exact volume of fluid or water needed to reach a “filled state” does not need to be determined in order to understand the metes and bounds of the claim so as to understand how to avoid infringement. We are further persuaded because this is consistent with the district court’s construction of this term. See Ex. 1023, 19–20.” slip op. at 17

    • Disclosure Requirements (§112) › Written description (Ariad)Written description adequateNot shown unpatentable

      “Based upon our review of the specification, and consideration of the arguments and evidence presented, Petitioner’s position is not persuasive. We agree with Patent Owner that Petitioner has failed to show that the ’612 patent does not provide such adequate guidance to a person of ordinary skill in the art. On its face, Figure 1 of the ’612 patent (reproduced below) shows containers 18 in contact or pressing against one another with the reasonable clarity required by Vas–Cath Inc. Figure 1 of the ’612 patent is reproduced above. Although the ’612 patent describes, as Petitioner notes, that tubes 16 can be different lengths, we are not persuaded that the ’612 patent’s disclosure of an embodiment with different tube lengths detracts from the concurrent disclosure in Figure 1 of an embodiment, where it is difficult to describe containers 18 as being not in contact with each other. Additionally, we agree with Patent Owner that Petitioner has failed to show adequately that a person of ordinary skill would not have understood the ’612 patent as describing the containers in Figure 1 as pressing against one another in an unfilled state. The ’612 patent indicates Figure 1 shows elastic valve 20A in an open configuration when container 18A is attached to tube 16A to allow container 18A to fill with fluid. Ex. 1001, 3:14–18. In this open configuration, container 18A is to be filled with fluid, after which, “it may be removed from tube 16A, whereupon elastic valve 20A closes, thereby closing the neck of container 18A and sealing the fluid inside.” Id. at 3:18–21 (emphasis omitted). The ’612 patent refers to Figure 1 to describe an embodiment where elastic valve 20A is in an open configuration to fill a container that has not been filled (i.e., unfilled) and removed from tube 16A. Thus, we are persuaded that, at least, Figure 1 and this accompanying description of Figure 1 in the ’612 patent provides sufficient written description for the recited limitation that “at least first and second ones of the plurality of containers are disposed sufficiently close to each other such that they press against each other . . . in a filled state or an unfilled state.”” slip op. at 21

      “We begin first with the claim language, and note that “three dimensional information” appears facially to be co-extensive with any information relevant to three dimensions. We discern that “length, width, and depth” are just such information. We have considered Patent Owner’s above-cited portions of the ’502 Patent, but are unpersuaded that those portions narrow “three dimensional information” with sufficient “reasonable clarity, deliberateness, and precision” such that one of ordinary skill would have understood “three dimensional information” as co-extensive with Patent Owner’s proffered construction. In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). For example, column 2, lines 42–48 and 51–55 certainly disclose that “volume” is desirable, but does not provide any equivalence between “three dimensional information” and “volume.” Indeed, column 2, lines 54–55 disclose “provide information regarding the location of soft-tissue target volumes,” indicating that “information” is a subset of “volume.”” slip op. at 8

      “Dr. Balter, Petitioner’s expert, proffers that a hypothetical person of ordinary skill in the art, with respect to and at the time of the’502 patent, would have the following qualifications: “a medical physicist with a Ph.D. (or similar advanced degree) in physics, medical physics, or a related field, and two or more years of experience in radiation oncology physics and image processing/computer programming related to radiation oncology applications.” Ex. 1302 ¶ 14. Dr. Hashemi, Patent Owner’s expert, essentially agrees, with the only major differences to the above being that an M.S. is acceptable in lieu of a Ph.D, and that three years of experience is preferred. Ex. 2080 ¶ 17. Nominally, we accept Petitioner’s proffered level of ordinary skill in the art based on Dr. Balter’s more complete explanation. We note, however, that neither party has explained substantively any significance that the difference in the proffered levels of ordinary skill in the art would have in the obviousness analysis.

Patent Owner asserts that one of ordinary skill would not have modified the radiation therapy systems of Adler/Depp to include the CBCT/FPI system of Cho/Antonuk/Jaffray 1997, because both timing and dosage considerations teach away from the proposed combination. PO Resp. 29–36. We disagree. We begin with timing considerations. PO Resp. 29–34. Fundamentally, Patent Owner asserts that replacing the orthogonal 2-D images projections of Adler/Depp with the CBCT acquired images of Cho/Antonuk/Jaffray 1997 would represent “very poor methodology” because the CBCT system takes a significantly longer period of time to acquire and process images from a patient than the 2-D image system, e.g., 60 seconds to acquire the image, and 30–50 minutes to reconstruct the entire CT conebeam data set. PO Resp. 33–34. According to Patent Owner, such a delay is detrimental in the context of sending targeted radiation to a specific volume within the patient, because during that time, the patient from whom the images was acquired would most likely have shifted positions. PO Resp. 33–35. We are unpersuaded for several reasons. Primarily, we are unpersuaded because a fundamental assumption made by Patent Owner is that the patient must remain unrestrained. Patent Owner makes this assumption based on the assertion that “the primary goal of the Adler/Depp systems is to permit a patient to be relatively unrestrained during the radiotherapy procedure.” PO Resp. 31. We have reviewed Patent Owner’s supporting evidence, and are unpersuaded that the evidence supports Patent Owner’s assertion that “the primary goal of the Adler/Depp systems is to permit a patient to be relatively unrestrained during the radiotherapy procedure.” For example, Patent Owner cites to certain paragraphs of Dr. Hashemi’s Declaration, which in turn cite to certain portions of Depp. Ex. 2080 ¶¶ 107, 123, 126 (citing Ex. 1304, 11:66–12:23, Fig. 9). We have reviewed those portions of Depp, and find that while they do disclose that target location and treatment periods are on the order of seconds, they do not mention anything about “the primary goal of the Adler/Depp systems is to permit a patient to be relatively unrestrained during the radiotherapy procedure.”11 Accordingly, absent such an evidentiary foundation, we do not find credible Dr. Hashemi’s assertions concerning this matter. Even without explicit analysis by Patent Owner, we logically understand the connection between longer image acquisition and processing times, and the higher likelihood of interim patient movement. Absent the aforementioned “primary goal,” however, we are unclear as to why the converse of that goal would not be correct, i.e., that one of ordinary skill would have resolved the timing consideration by restraining the patient.” slip op. at 19

Finally, in regard to assertions set forth in the Declaration of Dr. Hashemi, we discern some merit in his assertion that when reading the claim limitation “three dimensional information” in conjunction with another claim limitation “cone-beam computed tomography,” “a CBCT image is a volumetric image that provides the location, shape, and spatial orientation of the target volume in all directions, not just its length, width, and depth.” Ex. 2080 ¶ 85. The claim limitation at issue, however, reads “an image of said object, wherein said image contains at least three dimensional information of said object based on one rotation of said x-ray source around said object” (emphasis added). Accordingly, the claim limitation does not preclude an image having more information than “information concerning three dimensions of an object (such as length, width, and depth),” such as “a volumetric image of an object generated by reconstructing 2-D projection images.” Under Patent Owner’s construction, however, the image would be required to have such information. We are unpersuaded that such information is required under a proper construction of “three dimensional information” for the reasons set forth supra. We construe “three dimensional information” as “information concerning three dimensions of an object (such as length, width, and depth).”” slip op. at 7

      “D. The Challenged Claims – Obviousness over Jaffray 1999 SPIE, Jaffray 1999 JRO, Adler, and Depp Petitioner asserts that a combination of Jaffray 1999 SPIE, Jaffray 1999 JRO, Adler, and Depp renders obvious claims 1–14, 16–29, 33, and 35–38. Pet. 18–58. Petitioner relies solely upon Jaffray 1999 SPIE and Jaffray 1999 JRO for several limitations of claim 1, including, for example, “a cone-beam computed tomography system comprising: an x-ray source that emits an x-ray beam in a cone-beam form towards said object,” and “a flat-panel imager receiving x-rays after they pass through the object, said imager providing an image of said object.” Pet. 29–31. As discussed above, however, we not persuaded that Jaffray 1999 SPIE and Jaffray 1999 JRO are prior art to claims 1–14, 16–29, 33, and 35–38. Moreover, Petitioner does not contend that Adler or Depp teach these limitations. As a result, we are not persuaded that Petitioner has met its burden of showing, by a preponderance of the evidence, that claims 1–14, 16–29, 33, and 35–38 are obvious over a combination of Jaffray 1999 SPIE, Jaffray 1999 JRO, Adler, and Depp.” slip op. at 31

      “on Yan to disclose reevaluating and reoptimizing a radiation treatment plan. Pet. 42 (citing Ex. 2010, 11). Petitioner relies on Adler/Depp to meet the claim limitation of “substantially at a time.” Id. at 33‒34, 55. Patent Owner’s arguments are unpersuasive because they are directed to each individual reference’s failure to disclose the claim limitations, rather than to the combination of prior art disclosures. See In re Merck & Co. Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986). Although we recognize that the modifying of the radiation therapy treatment plan cannot simply be divorced from the modification occurring “substantially at a time,” Patent Owner’s argument does not rebut sufficiently Petitioner’s argument that a person with ordinary skill in the art would have combined Yan’s modification of the treatment plan such that it occurs “substantially at a time,” as the systems of Adler/Depp. As argued by Petitioner, a person with ordinary skill in the art would have been motivated in order to improving the accuracy and efficacy of radiotherapy through image-guided means. Pet. 44. Furthermore, Patent Owner’s argument does not set forth persuasive evidence why a person of ordinary skill in the art, reading Yan in combination with Adler/Depp, would not have known to modify a treatment plan “substantially at a time” of receiving 3-D images in order to improve accuracy and efficacy, as asserted by Petitioner, and would have had to perform the modification of the treatment plan off-line.

We discern that “length, width, 6 In evaluating the assertions set forth in the Declaration of James Balter Ph.D. in Support of Petitioner’ Reply (Ex. 1500), we considered Patent Owner’s Motion for Observations on the Cross-Examination of Dr. James Balter (Paper 48) and Petitioner’s Response to Patent Owner’s Motion for Observations on Cross-Examination (Paper 56). 7 In the Decision on Institution, we preliminarily agreed with Petitioner’s proposed construction of “three-dimensional information.” Dec. 9–10. and depth” are just such information. We have considered Patent Owner’s above-cited portions of the ’765 patent, but are unpersuaded that those portions narrow “three-dimensional information” with sufficient “reasonable clarity, deliberateness, and precision” such that one of ordinary skill would have understood “three-dimensional information” as co-extensive with Patent Owner’s proffered construction. In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). For example, column 2, lines 44‒56 certainly disclose that “volume” is desirable, but does not provide any equivalence between “threedimensional information” and “volume.” Indeed, column 2, lines 55–56 disclose “provide information regarding the location of soft-tissue target volumes,” indicating that “information” is a subset of “volume.” In another example, column 3, lines 41–56, mentions “three-dimensional (3-D) images,” which we agree would appear to require “volumetric data;” however, the claim limitation at issue is the broader term “three-dimensional information.” In a further example, column 9, line 54‒64, clearly refers to “volumetric data,” but does not indicate its relation to “three-dimensional information.” In yet another example, column 16, lines 23–25 and 38–42, do not recite “three-dimensional information,” instead disclosing “3-D structure” and “3-D nature” in relation generally to “volumetric data,” but, again, not in a manner sufficient to indicate a particular relationship. Finally, in regards to assertions set forth in the Declaration of Dr. Hashemi, we discern some merit in his assertion that when reading the claim limitation “three-dimensional information” in conjunction with another claim limitation “cone-beam computed tomography,” “a CBCT image is a volumetric image that provides the location, shape, and spatial orientation of the target volume in all directions, not just its length, width, and depth.” Ex. 2080 ¶ 85. Furthermore, the claim limitation does not preclude an image having more information than “three-dimensional information concerning said object” (such as length, width, and depth), “based on a plurality of two-dimensional projection images.” Under Patent Owner’s construction, however, the image would be required to have such information. We are unpersuaded that such information is required under a proper construction of “three-dimensional information” for the reasons set forth supra. We construe “three-dimensional information” as “information” slip op. at 8

      “We are unpersuaded for several reasons. Primarily, we are unpersuaded because a fundamental assumption made by Patent Owner is that the patient must remain unrestrained. Patent Owner makes this assumption based on the assertion that “the primary goal of the Adler/Depp systems is to permit a patient to be relatively unrestrained during the radiotherapy procedure.” PO Resp. 33. We have reviewed Patent Owner’s supporting evidence, and are unpersuaded that the evidence supports Patent Owner’s assertion that “the primary goal of the Adler/Depp systems is to permit a patient to be relatively unrestrained during the radiotherapy procedure.” For example, Patent Owner cites to certain paragraphs of Dr. Hashemi’s Declaration, which in turn cite to certain portions of Depp. Ex. 2080 ¶¶ 117, 133, 136 (citing Ex. 1104, 11:66–12:23, Fig. 9). We have reviewed those portions of Depp, and find that while they do disclose that target location and treatment periods are on the order of seconds, they do not mention anything about “the primary goal of the Adler/Depp systems is to permit a patient to be relatively unrestrained during the radiotherapy procedure.”11 Accordingly, absent such an evidentiary foundation, we do not find credible Dr. Hashemi’s assertions concerning this matter. Even without explicit analysis by Patent Owner, we logically understand the connection between longer image acquisition and processing times, and the higher likelihood of interim patient movement. Absent the aforementioned “primary goal,” however, we are unclear as to why the converse of that goal would not be correct, i.e., that one of ordinary skill would have resolved the timing consideration by restraining the patient. Indeed, in opposition, Petitioner asserts, and we agree, that “POSA would understand that in the majority of radiotherapy treatment settings, patients are in fact restrained to some degree.” Pet. Reply 7‒8 (citing Ex. 1500 ¶¶ 33–35; Ex. 2080 ¶¶ 54–55; Ex. 1502, 142:23–143:19).

See Pet. 36‒38 (citing Ex. 1005, 17, 25; Ex. 1006, 9; Ex. 1002 ¶¶ 82‒84). Independent claims 7, 20, and 26 recite substantially similar limitations that Petitioner again solely relies on Jaffray 1999 SPIE and Jaffray 1999 JRO as disclosing these limitations. As discussed above, however, we not persuaded that Jaffray 1999 SPIE and Jaffray 1999 JRO are prior art to claims 1–13 and 20‒31. Moreover, Petitioner does not contend that Adler or Depp teach these limitations. As a result, we are not persuaded that Petitioner has met its burden of showing, by a preponderance of the evidence, that claims 1–13 and 20–31 are obvious over a combination of Jaffray 1999 SPIE, Jaffray 1999 JRO, Adler, and Depp.” slip op. at 32

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “We are persuaded that our preliminary interpretation of “session” in our Decision on Institution is, at least in some respect, overly broad. Independent claims 1, 6, 7, and 10 each refer to “sessions” in plural, and independent claim 7 refers to “simultaneous” sessions. Thus, the term “session” must be understood, at least, in such a manner as to allow multiple sessions to be distinguished from one another. Although independent claim 5 does not recite “sessions” in plural, the same term should be construed consistently across all claims. Accordingly, we conclude that there must be sufficient delineation within a proper construction of “session” that separates a “session” between one client and one server and a different “session” when one of the client and server are replaced, and that separates multiple sessions from each other even between the same pair of client and server. During Oral Hearing there were extensive discussions regarding proper construction of “session.” See Tr. 7:9–22:18, 43:11–65:15, 74:21–76:13. At Oral Hearing, counsel for Petitioner agreed that “session” should be understood as communications having a recognizable beginning and a recognizable end. Id. at 10:13–16 (“Of course a session has a beginning and an end. I think that is axiomatic in a session. I think that is how Dr. Rubin defined it in his declaration”); see also id. at 12:21–13:5, Ex. 1005 ¶ 41. Patent Owner also agreed that if the construction of session is made to include a recognizable beginning and a recognizable end, that would be a proper construction for the term:” slip op. at 12

      “We agree with Patent Owner that Petitioner has failed to identify what constitutes a “session” in Feinberg in accordance with a proper construction of “session.” That proper construction of “session” is set forth above and has been agreed to by the parties. Tr. 10:13–16, 53:13–54:10. We state it again here: “a set of transmitters and receivers, and the data streams that flow between them wherein each data stream flowing between the transmitters and receivers has a recognizable beginning of the data stream transmission and a recognizable end of the data stream transmission.” Petitioner identifies Feinberg’s disclosure of forwarding (shunting) received requests from the primary server to secondary servers (for purposes of load balancing) teaches the recited “communication between the main server and agent server enlists additional agent servers to support incremental secure sessions in response to maintaining performance at a desired level.” Pet. 21–23 (emphasis added). The analysis is excessively generic for the claim recitation of “incremental secure sessions.” It is uncertain what Petitioner regards as a session in Feinberg much less how it begins and how it ends. It is unexplained by Petitioner whether a request in Feinberg begins a session, or something else in Feinberg begins a session. We decline to speculate in that regard. It is Petitioner who bears the burden of proof, and who must account for all the limitations in a claim. In that regard, we note further that it is insufficient for Petitioner to present only dots that may be connected in some unspecified manner to yield the claimed invention. Instead, Petitioner must make a sufficient connection through the dots to demonstrate a full accounting of the claimed invention.” slip op. at 22

      “that the system supports “incremental secure sessions.” The Petition relies on Feinberg for disclosing such sessions, presenting the same arguments as those it presents for claim 6. See Pet. 33–34. Patent Owner argues Feinberg fails to disclose sessions for the same reasons as those that Patent Owner presented with respect to claim 6. See PO Resp. 36–37. Petitioner’s Reply asserts essentially the same arguments for claim 1 as it does for claim 6 regarding “incremental secure sessions.” Pet. Reply 17. Petitioner does not rely on Bhaskaran to alleviate the above-identified deficiency in the analysis of Feinberg with respect to claim 6. The standard for obviousness under 35 U.S.C. § 103(a) is what would have been taught or suggested to the ordinarily skilled artisan with based on the references. The key to supporting any prima facie conclusion of obviousness under 35 U.S.C. § 103 is the clear articulation of the reason(s) why the claimed invention would have been obvious and, the Court has noted that, the analysis supporting an obviousness assertion should be made explicit. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007)). A “legal determinations of obviousness, as with such determinations generally, should be based on evidence rather than on mere speculation or conjecture.” Alza Corp. v. Mylan Labs., Inc., 464 F.3d 1286, 1290 (Fed. Cir. 2006). As discussed supra, Petitioner failed to account adequately for the recited “sessions.” Therefore, Petitioner has failed to establish by a preponderance of the evidence that independent claims 1, 6, and 10 would have been obvious over Feinberg and Bhaskaran and, for the same reasons, has failed to establish claim 3, dependent from claim 1, would have been obvious over Feinberg and Bhaskaran.” slip op. at 24

      “Initially, we note Patent Owner’s Motion to Exclude fails to identify the portions of Dr. Rubin’s Declaration that allegedly fail to be based upon sufficient facts or data, that allegedly are the product of unreliable principles and methods, or that allegedly fail to reliably apply sound principles and methods to the facts of the case. There is no requirement for an exact or perfect match between the expert’s experience and the field of the patent. SEB S.A. v. Montgomery Ward & Co., Inc., 594 F.3d 1360, 1372–73 (Fed. Cir. 2010). Thus, Patent Owner fails to meet its burden with respect to this Motion to Exclude. See 37 C.F.R. § 42.20(c). Furthermore, regarding the objections under FRE 702, we note that under 37 C.F.R. § 42.65(a), “[e]xpert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.” Consequently, this objection more properly goes to the weight to be given Dr. Rubin’s testimony, and not to its admissibility. In any event, Patent Owner’s argument, that Petitioner did not explain the evidentiary weight or standard that was applied by Dr. Rubin, is misplaced. We note that Dr. Rubin is an expert witness, not a fact finder or a tribunal making fact findings. Dr. Rubin need only provide his opinion and, preferably, also provide the underlying reasoning, inclusive of data and facts, in support of his opinion. For the above reasons, Patent Owner’s Motion to Exclude is denied.” slip op. at 27

Instead, Petitioner must make a sufficient connection through the dots to demonstrate a full accounting of the claimed invention. Petitioner had ample notice of the possibility of a narrower interpretation of “session.” See PO Resp. 7–11, 23–24. Indeed, Petitioner responded to that possibility by referring to its own expert’s testimony that the beginning and end of a session may be signified in a variety of forms. Pet. Reply 2. See Genzyme Therapeutic Prod. Ltd. P’ship v. Biomarin Pharm. Inc., 825 F.3d 1360, 1367 (Fed. Cir. 2016) (“The critical question for compliance with the APA and due process is whether [the parties] received ‘adequate notice of the issues that would be considered, and ultimately resolved, at [the] hearing’”) (internal citation omitted). Nevertheless, Petitioner’s Reply still does not specifically identify a “session” within Feinberg that accounts for what constitutes a session in Feinberg, including when it begins and ends. Claim 10 recites, in pertinent part, “sharing spare CPU cycles of the computer network for encrypting and decrypting communication to provide N simultaneous secure session[s] among said network of computers.” Petitioner’s analysis with respect to the recitation of “N simultaneous secure session[s]” is deficient for the same reasons we discussed above with respect to the recitation of “incremental secure sessions” in claim 6. For the above reasons, we are not persuaded Petitioner has established, by a preponderance of the evidence, that claims 6 and 10 are anticipated by Feinberg.” slip op. at 22
