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

    “phrase creates a degree of ambiguity, we are mindful that “the claims themselves provide substantial guidance as to the meaning of particular claim terms” and that “the context in which a term is used in the asserted claim can be highly instructive.” Phillips, 415 F.3d at 1314. In this instance, the related phrasing that appears in the “automatically adding” and “causing” limitations of issued independent claim 1 is illuminating. Both of those limitations refer to “the controllable function of the controllable appliance that was identified by the data received from the controllable appliance.” Ex. 1001, 17:11–14, 17:21–24 (emphasis added). There is no question that the only antecedent for “the data” in these limitations is the “data that functions to identify a controllable function of the controllable appliance” recited in the “receiving” limitation. See id. at 17:8–9. And there is no apparent room in the language “that was identified by the data” for the introduction or consideration of such “other information” that Petitioner would like to use “in connection with” the recited “data” to identify the controllable function. See Reply 2.” slip op. at 19

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

    “Petitioner reasons that a person of ordinary skill in the art would have combined such teachings from HDMI 1.3a with Chardon’s system because HDMI 1.3a “is a technical guide for the interoperability of the HDMI standard and how HDMI enabled devices operate,” and that “Chardon relies on HDMI capabilities to facilitate communication and monitoring-device state changes in its system.” Pet. 30–31 (citing Ex. 1005, 4:18–21; Ex. 1010, 17; Ex. 1003 ¶¶ 130–131). According to Petitioner, “[a] person of ordinary skill in the art would have therefore turned to at least one of the versions of the HDMI Specification to fill in any details in Chardon with respect to how HDMI-capable devices, such as those of Chardon and the ’486 patent operate, and would have had a reasonable expectation of success in doing so.” Id. at 31. Petitioner supports this reasoning with testimony by Dr. Russ that it is a “well-known industry practice” to rely on HDMI 1.3a as “specification of an industry standard” when “designing and building devices that implement the HDMI standard, incorporating all of the capabilities it offers.” Ex. 1003 ¶ 133.

    “The difficulty with Petitioner’s and Dr. Russ’s position is that it is inconsistent with our adopted claim construction that the data itself identify a controllable function of the controllable appliance from which the data is received. See supra § II.C. As Patent Owner asserts, HDMI 1.3a “does not contemplate the exchange of any information that itself functions to identify a controllable function of a playback device.” PO Resp. 24 (emphasis added). All that the “Deck Status” message indicates in the example of Figure 17 is that the current status of the playback device is “Stop.” We also are not persuaded by Petitioner’s and Dr. Russ’s argument that HDMI 1.3a’s Tables 13 and 26 disclose that “Deck Info” information is returned with the “Deck Status” message, and that such “a deck status message includ[es] the features that the device can provide (e.g., play, pause, stop, etc.).” Pet. 41; Ex. 1003 ¶ 117. Reliance on such “Deck Info” information is problematic at least because it is “other information” that would be used in combination with the “Deck Status” to determine controllable functions of the controllable device, which is precluded by our adopted claim construction.” slip op. at 36

    “As discussed above (supra § III.E.4.a), Petitioner’s papers fail to link Dr. Reader’s declaration testimony on the level of ordinary skill in the art to the analogous art inquiry and fail to identify a field of endeavor for the ’792 patent. We therefore agree with Patent Owner that Petitioner’s demonstrative slide 53 presents improper new arguments that have not been previously made. See Paper 38, 2 (“The parties may only rely upon evidence that has been previously submitted in the proceeding and may only present arguments that have been previously made in the submitted papers. No new evidence or arguments may be presented at the hearing.”), 5 (“Demonstratives are not a mechanism for making new arguments.”). We therefore sustain Patent Owner’s objections.

    “Although a claim term that does not include the word “means” is presumed not to invoke a means-plus-function analysis, that presumption may be overcome if the limitation does not “recite sufficiently definite structure” or recites a “function without reciting sufficient structure for performing that function.” Williamson v. Citrix Online, LLC, 792 F.3d 2 Section 4(c) of the Leahy-Smith America Invents Act (“AIA”) redesignated 35 U.S.C. § 112, ¶ 6, as 35 U.S.C. § 112(f). Pub. L. No. 112- 29, 125 Stat. 284, 296 (2011). Because the ’703 patent has a filing date before September 16, 2012 (effective date of § 4(c)), we refer to the pre-AIA version of § 112. 1339, 1349 (Fed. Cir. 2015). Petitioner’s expert, Russell J. Hamilton, Ph.D., testifies that “the term ‘logic’ would not be recognized by one of ordinary skill in the art as providing sufficiently definite structure for performing the claimed functions,” and that “[l]ogic can be implemented in software, in hardware, and in combinations of hardware and software.” Ex. 1021 ¶ 122. The parties provide sufficient reasoning to overcome the presumption against a means-plus-function construction, and we accordingly construe “first logic” and “second logic” in accordance with 35 U.S.C. § 112 ¶ 6.” slip op. at 9

  • Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Term construed patent owner constructionDecided for patent owner

    “untenable because its broad identification only of “computer software and/or computer hardware” as structure for performing the recited function is too generic. The law regarding construction of means-plus-function limitations as applied to computer-implemented elements is well-established: For computer-implemented means-plus-function claims where the disclosed structure is a computer programmed to implement an algorithm, “the disclosed structure is not the general purpose computer, but rather the special purpose computer programmed to perform the disclosed algorithm.” . . . This court permits a patentee to express that algorithm in any understandable terms including as a mathematical formula, in prose, . . . , or as a flow chart, or in any other manner that provides sufficient structure. Finisar Corp. v. DirecTV Group, Inc., 523 F.3d 1323, 1340 (Fed. Cir. 2008) (citations omitted). Patent Owner’s proposed construction is superior because it identifies the algorithm through explicit reference to the flow chart of Figure 4 and related disclosure in the Specification. Patent Owner’s position is supported by testimony of its expert, Sasa Mutic, Ph.D., who refers to those disclosures in opining that “the [’703] patent describes a process of steps for obtaining the result of properly positioning a patient to begin a treatment” and that “Fig. 4 of the [’703] patent provides a flowchart of a process for use of an embodiment of the invention.” Ex. 2012 ¶ 69. Petitioner takes the position that the ultimate scope of the corresponding algorithm “does not matter” because Petitioner contends that the challenged claims are unpatentable even under Patent Owner’s proposed construction. Pet. Reply 315, 3. Nevertheless, Petitioner attacks Patent Owner’s proposed construction as “implicitly adopt[ing]” two “additional but unreasonable limitations.” Id. First, Petitioner contends that “the claims do not require the performance of the function of the second logic to be fully automated and instead permit human interaction with the second logic.” Id. Second, Petitioner contends that blocks 520 (“Position Patient”), 525 (“Register Treatment Image Data with Simulator/Reference Image Data and Reposition Patient”), and 530 (“Position Clinical Treatment Machine”) of Figure 4 “need not be performed in their entirety by logic so long as the second logic is used for some step in each block.” Id. at 4. We find no inconsistency in these positions with Patent Owner’s proposed construction. In light of the foregoing considerations, we adopt Patent Owner’s proposed construction.” slip op. at 14

Reply 315, 1. Petitioner cites no authority to support this position, which improperly focuses on only one limitation of the claims, divorced from the claims’ other limitations.

Patent Owner’s expert, Dr. Mutic, expresses a level of ordinary skill that is generally similar to Petitioner’s expert, but accounts for the possibility of a medical education instead of a medical-physics education: [A] person of ordinary skill in the art . . . would be 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. Alternatively, one of ordinary skill in the art might have an M.D. degree in the same relevant fields and two or more years of practical experience with image processing and the use of computer systems that is related to medical applications. Ex. 2012 ¶ 36. The similarity in the experts’ opinions is reinforced by Dr. Mutic’s assertion that he has “considered Dr. Hamilton’s definition of the level of ordinary skill in the art and determined that it does not differ from [his] own expressions of this concept in any way that is relevant to the opinions” he expresses in his Declaration.

  • Expert testimonyPetitioner expert discountedDecided for patent owner

    “We have considered the opinions of both experts and the underlying bases for those opinions. In light of specific disclosures in Chandnani, we conclude that Patent Owner’s expert, Dr. Medvidovic, articulates the more compelling position. Of particular relevance is the following disclosure from Chandnani: The script language virus detection methodologies described herein may be performed by a computer in one or a combination of the following circumstances. The script language virus detection methodologies may be performed periodically (e.g., once/twice per day) or at selected times (e.g., each time the computer is powered up or restarted) by the computer on all relevant electronic files. In addition, the script language virus detection methodologies may be performed on a file (or a data stream received by the computer through a network) before the file is stored/copied/executed/opened on the computer. Ex. 1003, col. 9, ll. 6–16 (emphasis added). In considering this passage, Petitioner’s expert, Dr. Rubin, makes the conclusory statement that “[t]hus, under [Patent Owner’s] own interpretation of the claim language, the Chandnani+Kolawa combination teaches the ‘dynamically building’ limitation.” Ex. 1002 ¶ 167. We accord such a conclusory assertion little weight. See Verlander v. Garner, 348 F.3d 1335, 1371 (Fed. Cir. 2003) (Board has discretion to accord little weight to broad conclusory statements from expert witness).” slip op. at 18

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “2. Level of Skill in the Art Based on its expert’s testimony, Petitioner contends that a person of ordinary skill in the art at the time of the claimed invention would have held a bachelor’s degree or the equivalent in computer science or related academic fields, and three to four years of additional experience in the field of computer security, or equivalent work experience. Pet. 2001, 14 (citing Ex. 1002 ¶ 33). Patent Owner does not dispute Petitioner’s contention, and its expert’s opinion on the level of ordinary skill is generally similar to that of Petitioner’s expert, differing only by about a year in minimum work experience and suggesting an advanced degree as a substitute for work experience. See Ex. 2007 ¶ 37. Furthermore, Patent Owner’s expert, Dr. Medvidovic, asserts that the opinions stated in his Declaration “would be the same if rendered from the perspective of a person of ordinary skill in the art set out by [Petitioner’s expert,] Dr. Rubin.” Id. at ¶ 40. Based on the expert testimony in the record, we agree with and adopt the level of skill advocated by Petitioner.” slip op. at 10

    “The dispositive issue is whether Petitioner demonstrates, by a preponderance of the evidence, that the combination of Chandnani and Kolawa teaches or suggests “dynamically building” a parse tree “while” receiving an incoming stream of program code. Although the specific language differs in immaterial respects by reciting or omitting the structural elements of a “computer” or a “receiver,” such a limitation appears in each of independent claims 1, 9, 22, 23, 29, and 35 through a combination of recitations that include receipt of the incoming stream of programming code and “dynamically building” the parse tree “while” receiving the incoming stream. Petitioner contends that all limitations of independent claims 1, 9, 22, 23, 29, and 35 are taught by Chandnani “except for the use of a parse tree to store and analyze programming code,” and that “[i]t would have been obvious to combine Chandnani’s scanner with the parse-tree teachings of Kolawa” to meet the full set of limitations of each independent claim. Pet. 2001, 19–20. Although the parties agree that Chandnani describes lexical analysis of a “data stream” to generate a stream of tokens, they disagree whether Chandnani discloses that such lexical analysis occurs while receiving the incoming data stream, as recited in each of the independent claims. That is, the parties disagree whether Chandnani discloses a time period for generation of the token stream that overlaps a time period during which the incoming stream is received, as required by our construction of “dynamically building.”” slip op. at 16

  • Obviousness (§103) › Objective indicia / secondary considerationsNot reached

    “5. Conclusion Having considered the arguments and evidence presented by both parties, we conclude that Petitioner has not shown, by a preponderance of the evidence, that any of challenged claims 1, 9, 22, 23, 29, or 35 would have been obvious over the combination of Chandnani and Kolawa, or would have been obvious over that combination in further combination with Walls. Because the challenges of the dependent claims suffer from the same deficiencies, we further conclude that Petitioner has not shown, by a preponderance of the evidence, that those dependent claims would have been obvious over the combinations of art it presents. Because we determine that the art does not disclose “dynamically building” a parse tree “while” receiving an incoming stream of program code, we need not consider whether a further conclusion of nonobviousness is warranted because of evidence of secondary considerations.” slip op. at 24

    “D. OBVIOUSNESS GROUND BASED ON ROSS The Petition relies on Ross as teaching or suggesting all the limitations of claims 18, 10, and 11. Pet. 1437. Having reviewed the arguments and evidence provided by Petitioner and the arguments and evidence presented by Patent Owner, we determine that Petitioner has failed to show by a preponderance of the evidence that Ross teaches or suggests all the limitations of the challenged claims, and more particularly, “the content including a call to a first function.”” slip op. at 11

    “first function.” But the Specification uses the phrase “function call” in stating that “before the client computer invokes a function call that may potentially dynamically generate malicious code, the client computer passes the input to the function to the security computer for inspection.” Ex. 1001, 4:3842. The Specification also states that “the present invention operates by replacing original function calls with substitute function calls within the content, at a gateway computer, prior to the content being received at the client computer.” Id. at 4:5760. From such examples, we understand the Specification to use the phrase “function call” in the same sense that the claims recite in the phrase “call to a [] function.” That is, a “call” is part of the recited “content,” as a statement or instruction containing the function that, when executed, causes the function to provide a service. Thus, we find the dictionary definition of the term “function call” applicable here and indicative of the meaning of the term to a person of ordinary skill in the art.” slip op. at 7

    “3. Conclusion Having considered the arguments and evidence presented by both parties, we determine that Petitioner has not shown by a preponderance of the evidence that the challenged claims would have been obvious over Ross. Because we find that Ross does not teach or suggest “content including a call to a first function,” we need not consider whether Patent Owner succeeded in its attempt to prove the prior invention of the ’154 patent or whether a conclusion of nonobviousness is warranted because of evidence of secondary considerations of nonobviousness.” slip op. at 22

  • Strike new argumentNew argument disregardedDecided for patent owner

    “[w]hile replies can help crystalize issues for decision, a reply that raises a new issue or belatedly presents evidence will not be considered and may be returned. The Board will not attempt to sort proper from improper portions of the reply. Examples of indications that a new issue has been raised in a reply include new evidence necessary to make out a prima facie case for the patentability or unpatentability of an original or proposed substitute claim, and new evidence that could have been presented in a prior filing. Trial Practice Guide, 77 Fed. Reg. at 48767; see also Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1080 (Fed. Cir., 2015) (discussing that a patent owner “is undoubtedly entitled to notice of and fair opportunity to meet the grounds of rejection.”). With these guidelines in mind, we are persuaded that the above-identified argument in the Reply should not be considered in deciding this matter. As stated above, the Petition relies on Ross’s “hook functions within a hook script” as teaching or suggesting the “call to a first function.” Pet. 1718. Although the Petition relies on the understanding of a person of ordinary skill in the art when explaining Ross’s handling of the hook function, Petitioner does not assert in any meaningful way that Ross’s use of hook functions in the hook script would be modified to include calls to additional hook functions that Ross does not describe. Nor does Petitioner explain in the Petition that Ross would be modified to replace the assignment instruction with a call to the hook function. The arguments in the Reply are not explanations of how Ross’s hook functions, as taught by Ross, may be understood to include the recited “call to a first function,” as asserted in the Petition. Rather, the argument that a “call” may be added to either the security check or the hook script is an alteration of Ross, necessitated because Patent Owner correctly argues that Ross fails to teach or suggest the limitation. The contention that Ross’s embodiments would be modified, altered, or imbued with details not present in Ross is a new contention, necessary to make a case for the unpatentability of the claims, and should have been presented in the Petition. To consider the argument would unfairly prejudice Patent Owner who, after having argued there is a significant gap in Petitioner’s case, would be left without an opportunity to respond substantively to the new arguments and support its rebuttal with additional evidence, if necessary. Accordingly, we do not consider the improper arguments identified above.” slip op. at 20

  • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed patent owner constructionDecided for patent owner

    “ordinary meaning of “bias signal” is “a signal having a steady predetermined level.” Resp. 28; Reply 6–7. The parties also agree that at least some information signals may be considered “bias signals.” The crux of the parties’ disagreement is which type of information signal. The ’940 patent defines “information signal” as “[t]he signal that contains the information that is to be transmitted. As used herein, it refers to the original baseband signal at the source.” Ex. 1001, 8:48–50 (emphasis added). Thus, the ’940 patent clearly defines “information signal” as “the original baseband signal at the source.” The ’940 patent defines “baseband signal” as: Any generic information signal desired for transmission and/or reception. As used herein, it refers to both the information signal that is generated at a source prior to any transmission (also referred to as the modulating baseband signal), and to the signal that is to be used by the recipient after transmission (also referred to as the demodulated baseband signal). Ex. 1001, 7:41–47. The ’940 patent clearly gives a broad meaning to “baseband signal” such that it encompasses any signal desired for transmission and/or reception, but the definition of “information signal,” as quoted above, does not refer to any baseband signal. Rather, it refers to “the original baseband signal at the source.” Ex. 1001, 8:48–54. By including the terms “original” and “at the source,” the meaning of information signal, as defined by the ’940 patent, is more limited than the definition of a baseband signal. Thus, Petitioner’s contention that the meaning of “information signal,” and, hence, “bias signal” should be expanded to include any “baseband signal” (Reply 4) improperly takes “information signal” out of context. Petitioner’s contention eliminates the terms “original” and “at the source” from the ’940 patent’s definition of “information signal,” without providing any reason why those terms should not be considered. Accordingly, we agree with Patent Owner and construe “bias signal” to mean “(1) a signal having a steady, predetermined level or (2) the original baseband signal at the source.”” slip op. at 11

    “Further, Patent Owner explains that “[t]he parties agree on the portion of the ‘to gate’ construction that is material to this IPR, i.e., that ‘to gate,’ the switch module must change between connecting and disconnecting the bias signal from the switch module’s output.” Id. at 37 (citing Pet. 13–14). Patent Owner’s proposed construction is consistent with the construction proposed by Petitioner. See Dec. 11 (discussing Petitioner’s construction of “to gate [a signal]” as “to change . . . between (i) connecting a signal at an input to an output such that the input and output have an equal voltage, and (ii) disconnecting the signal from the output” (quoting Pet. 14)). In light of the consistency between the proposed constructions, and in light of the lack of an actual controversy between the parties with respect to the impact of the minor differences in the proposed meanings of this term, we need not construe expressly the term further.4 Petitioner’s Reply does not challenge Patent Owner’s arguments regarding these claim terms. Accordingly, we adopt the construction of “switch module,” as reproduced above, for the reasons explained in our Decision to Institute. See Dec. 8–11. Additionally, we decline to construe expressly the terms “summer” and “to gate,” for the reasons discussed above.” slip op. at 13

    “High Level Radio Frequency (“RF”) Source 10. The RF signal contains the information that television watchers see and hear.” Pet. 29 (citing Ex. 1023, 1:14–17). Petitioner asserts that Dobrovolny’s “RF Source signals are information signals that constitute ‘bias signals’ as that term is defined by the ‘940 patent.” Id. (citing Ex. 1002 ¶¶ 154, 210). Petitioner’s position is based on its claim construction of “bias signals” as “encompassing information signals.” Id. Notably, in the Petition,5 Petitioner does not assert that the recited “bias signal[s]” would have been obvious to one of ordinary skill in the art in light of Dobrovolny’s RF Source signals; rather, Petitioner’s position is that “bias signal[s]” are disclosed expressly. See id. (“RF Source signals . . . constitute ‘bias signals’”) (emphasis added).6 Patent Owner’s primary argument is as follows: [E]ven accepting [Petitioner’s] assertion that the ’940 patent expanded the ordinary meaning of ‘bias signal’ to include ‘information signal’ as defined in the patent . . . . [Petitioner] does not even allege, much less prove, that the purported ‘bias signal’—Dobrovolny’s high frequency Radio Frequency (RF) television signal—meets either of these definitions. Resp. 38–39. Patent Owner reiterates that Petitioner’s “only attempt to prove that the Dobrovolny RF television signal satisfies the claimed first and second bias signals is its assertion that Dobrovolny’s ‘RF signal contains the information that television watchers see and hear.’” Id. at 39 (quoting 5 As discussed infra, see Section III.C., Petitioner’s additional argument that bias signals would have been obvious in light of Dobrovolny’s RF Source signals constitutes a new argument, set forth only in Petitioner’s Reply, and we do not consider it here for the reasons explained below. 6 With respect to independent claim 18, Petitioner relies upon its arguments directed to the similar claim limitations of claim 1. See Pet. 44–45 (referring to Petitioner’s arguments directed to claim 1). Pet. 29). Patent Owner contends, however, that “an ‘information signal’ is not just any signal containing information . . . as [Petitioner’s] argument implicitly presumes. Rather, as defined in the ’940 patent, an information signal is restricted to ‘the original baseband signal at the source.’” Id. (quoting Ex. 1001, 8:48–54). Petitioner’s argument in its Reply is based on its incorrect claim construction of “bias signal” as encompassing any information signal. See, e.g., Reply 7 (asserting that the “bias signal” is met by Dobrovolny’s disclosure because it teaches “an information carrying High Level RF Source for reception”) (citing Ex. 1023, 1:14–17; Ex. 1002 ¶¶ 154, 210). As explained above, “bias signal” is understood to mean “(1) a signal having a steady, predetermined level or (2) the original baseband signal at the source.” See supra Section II.A. Petitioner does not argue, and has not established, that Dobrovolny’s RF Source signal is either at a steady, predetermined level or is the original baseband signal at the source. Thus, Petitioner has not shown that Dobrovolny discloses the “bias signal” limitations recited in claims 1 and 18, and the claims that depend from each.7 Accordingly, Petitioner has not shown, by a preponderance of the” slip op. at 19
