See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). Thus, for the purpose of our Institution Decision, we adopted Petitioner’s proposal. Institution Dec. 11. Post-institution, neither party has contested this description.

    “Ex. 1005 ¶ 0111. Dr. Rubin testifies, succinctly, that “I do not believe that a [person of ordinary skill] would understand that Tajima uses the term ‘information regarding the key’ to refer to the key. If Tajima meant to say the ‘key,’ there would be no need to use the phrase ‘information regarding the key.’” Rubin II Decl. ¶ 41. He further testifies that “[w]hen Tajima wishes to refer to a ‘key,’ it does so directly” (citing many instances where Tajima makes explicit reference to keys). Id. ¶ 42 (citing Ex. 1005 ¶¶ 67, 70, 71, 75, 77, 86, 88, 89). We find Dr. Rubin’s reasoning on this issue persuasive. On the other hand, we find Dr. Bhattacharjee’s response less convincing. Bhattacharjee II Decl. ¶¶ 5–23. We find that he does not 5 Petitioner states that it does not rely on the doctrine of inherency to establish that this limitation is met by Tajima. Pet. Reply 2. understand that Tajima uses the terms “information regarding the key” and “key information” to refer to an encryption key. Id. ¶ 5 (citing Bhattacharjee I Decl. ¶ 103, 131). Lacking support for disclosure of an encryption key in Tajima itself, Dr. Bhattacharjee turns to other references, including Foster. Id. ¶¶ 7–9. Dr. Bhattacharjee testifies that “Foster’s use of the term ‘key information’ to describe information that includes the key and additional information . . . explains why Tajima did not just say ‘key’ when referring to the information attached to the data fragments.” Id. ¶ 8. Dr. Bhattacharjee’s testimony is unconvincing. In Foster, there is explicit disclosure of including the encrypted title key itself in the header extension. Ex. 1006 ¶ 66 (“As depicted, header extension 118 includes encrypted title key 112 . . . “). In contrast, Dr. Bhattacharjee cites no similar disclosure in Tajima. In fact, Dr. Bhattacharjee’s reliance on other references to support anticipation runs contrary to the rule that “[a] claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v. Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed. Cir. 1987) (emphasis added). We do not find Dr. Bhattacharjee’s testimony based on Foster and other references convincing of anticipation by Tajima. Nor do we find Petitioner’s alternative obviousness challenge based on Tajima persuasive. Pet. 22. The Petition includes a single-sentence explanation of this obviousness contention: “Even if Tajima had not disclosed that its key information includes the corresponding key, that would have been an obvious and conventional way to implement what Tajima discloses—i.e., a system that needs only the key information to decrypt data fragments and not additional key management infrastructure.” Id. (citing paragraph 104 of his initial declaration mirrors the Petition and provides no record citations to support his opinion of obviousness. Such unsupported expert testimony is entitled to little weight. “Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.” 37 C.F.R. § 42.65(a); PTAB Consolidated Trial Practice Guide 40 (Nov. 2019) (“Trial Practice Guide”) (“Opinions expressed without disclosing the underlying facts or data may be given little or no weight.”).6” slip op. at 17

    “Patent Owner responds that Petitioner “fails to demonstrate” a motivation to combine the references. PO Resp. 9. Patent Owner argues that “Tajima and Foster are directed to entirely different fields and to different problems.” Id. We disagree. As Petitioner points out, both Tajima and Foster are in the field of securing data, as is the ’116 patent. Pet. Reply 13–14 (citing Ex. 1005 ¶ 44; Ex. 1006 ¶ 3). Dr. Bhattacharjee testifies, “Tajima and Foster also both describe techniques for securing data using encryption and securely storing keys with encrypted data.” Bhattacharjee II Decl. ¶ 35 (citing Ex. 1005 ¶¶ 109–114; Ex. 1006 ¶¶ 64–71). Patent Owner argues Foster’s disclosure of a KEK would have been “redundant” to Tajima’s key-securing obfuscation technique. PO Resp. 18. We find this argument is unavailing. As Petitioner points out, Patent Owner’s argument “ignores Tajima’s vulnerability that Foster’s key-encryption addresses.” Pet. Reply 16. More specifically, “[r]equiring an attacker to obtain KEKs to decrypt Tajima’s encryption keys in addition to de-obfuscating them is not ‘redundant’ to only having to de-obfuscate them.” Pet. Reply 16 (emphasis omitted) (citing Bhattacharjee II Decl. ¶¶ 41–44). We find that Petitioner’s argument for combining the references is persuasive for the reasons given. Patent Owner further argues that Tajima and Foster address different problems and disclose solutions that are “fundamentally at odds.” PO Resp. 9–16, 25–27. Patent Owner asserts that “Foster’s system requires synchronizing the transmission of encrypted content packets with the keys used to encrypt those packets, so that each packet can be viewed immediately upon receipt.” Id. at 15 (emphasis omitted). Patent Owner attaching it to a different data fragment, the problem Foster sought to solve is the ‘need . . . for a key used to encrypt content to be itself encrypted, and transmitted as an integral part of the [same] content.’” Id. (alterations in original) (citing Ex. 1006 ¶ 7). We are not persuaded by this argument. As noted supra, for the reasons given, we find that both Tajima and Foster are in the field of securing data from unauthorized access. Pet. Reply 13. Furthermore, as Petitioner points out, we find that in Petitioner’s combination of Tajima and Foster, Tajima’s data (which does not require synchronization) is secured, not Foster’s. See Pet. 34–36 (providing reasons for encrypting Tajima’s keys); Pet. Reply 17–18 (“Synchronization of Foster’s data is irrelevant to Tajima-Foster because Tajima-Foster does not restore Foster’s data.”). Thus, we find that Patent Owner’s argument based on the need to synchronize Foster’s data for streaming is unavailing. We have considered Patent Owner’s other arguments and find them lacking. See, e.g., Patent Owner’s Sur-reply, which repeats the arguments that Tajima and Foster are in a “different field,” “fundamentally at odds,” “[i]n direct contrast,” and that applying Foster’s KEK teachings to Tajima would be “redundant.” PO Sur-reply 2–9.

    “Dr. Rubin explains that Kerckhoff’s Principle “holds that a cryptosystem should be secure, even if everything about the system, except the key, is public knowledge.” Rubin II Decl. ¶ 94. Citing this testimony, Patent Owner argues, “Shyu’s anti-piracy system is a prototypical attempt to achieve security through obscurity, to the extent it proposes to conceal or obscure the encryption algorithms.” PO Resp. 33. Petitioner does not persuasively respond to this argument. Pet. Reply 20–21. Petitioner argues that “Shyu does not use secret algorithms.” Id. at 20. Instead, according to Petitioner “Shyu selects from among known algorithms to secure different data segments.” Id. However, we find Shyu’s disclosure that “the scrambling algorithm and the key word for the source data are dynamically changed to effectively guard against piracy” is telling evidence that the underlying algorithms themselves are not secure, and therefore Kerckhoff’s principle applies here. See Ex. 1016, 1:37–39. We also find persuasive reasoning in Patent Owner’s assertion that “[c]ombining associated with maintaining multiple encryption algorithms and tracking encryption algorithm ‘metadata,’ without providing any substantial security.” PO Resp. 34–35. In sum, for the reasons given, we agree with Patent Owner that Petitioner fails to prove sufficiently that a person of ordinary skill would have been motivated to combine Tajima and Rivest. Further, Petitioner fails to demonstrate that even assuming that Tajima and Rivest would have been combined, a person of ordinary skill would have further combined their teachings with Shyu.” slip op. at 25

As to the earlier instituted claims, the Court instructed that we should consider “whether Samsung has shown that there would have been a reasonable expectation of success in combining the teaching of Gerpheide with the teachings of Ingraham [I]/Caldwell to arrive at the claimed invention.” Id. at 697. The Court further instructed us to “consider the patentability of claims 37, 38, and 39” (id.) because, on April 24, 2018, the Supreme Court of the United States held that a decision to institute under 35 U.S.C. § 314 may not institute on fewer than all claims challenged in the petition.

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

    “transition term[s]” should be considered in determining the meaning of a claim term, but asserts without further support that the presence of a semicolon after “supply voltage” and the use of the transition term “wherein” do not compel the preliminary construction. Id. As we addressed in denying Petitioner’s Request for Rehearing, claim 37 employs the open-ended transition term “comprising” followed by a colon to indicate that a list elements follows, and employs semicolons to separate the elements of that list. Paper 17, 5. The first element of the list, element 37a, describes an oscillator and includes the supply voltage limitation preceded by a comma and the transition term “wherein.” Id. Element 37a then ends with a semicolon and the claim proceeds to element 37b, which recites a microcontroller. Id. Petitioner thus nominally acknowledges consideration of punctuation, but advances a construction that asks us to disregard punctuation affirmatively recited in the claim. To do so would be “inconsistent with the punctuation [patentee] chose for this claim.” In re Pelz, 379 F. App’x 975, 978 (Fed. Cir. 2010). Likewise, as to Petitioner’s assertion that we read an additional limitation into the claim (Pet. Br. 10), we observe that, if the claim is limited to a particular exemplary embodiment, such a limitation results from the claim being drafted to cover only that embodiment. While we confirmed in the Decision on Institution that the use of the term supply voltage is consistent with its use in the Specification (Dec. on Inst. 9), the limitation of the claim to the oscillator is based on the language of the claim, not on definition or disavowal. Therefore, even accepting, for the sake of argument, that there is no disavowal or definition in the Specification of “supply voltage,” the term refers in independent claim 37 to supply voltage of the oscillator.” slip op. at 18

    “We disagree with Patent Owner’s arguments because they are not responsive to the combination of teachings at issue in the references before us. Patent Owner focuses on particular features of Gerpheide that it alleges either “would not work . . . in the proposed Caldwell-Ingraham system” or “can only work” in the presence of a component Patent Owner argues that “neither Ingraham nor Caldwell uses.” PO Br. 1–2, 12–13. These arguments are based on a mistaken premise that one or more components or physical configurations of Gerpheide must be incorporated into the combination of Ingraham I and Caldwell in order to show a reasonable likelihood of success. Under the Federal Circuit’s construction of the “selectively providing” limitation, the combination of Ingraham I, Caldwell, and Gerpheide need not incorporate the specific features of Gerpheide identified by Patent Owner. Petitioner asserts, supported by evidence from Dr. Subramanian, that the Ingraham I-Caldwell combination would have been modified based on Gerpheide “to provide features that adjust[] the oscillator signal frequency provided to the input portions 13 to negate the effect of interference on the input portions 13 and touch sensing circuits.” Pet. 26–27. This modification would not require any of the particular components or configurations of Gerpheide highlighted by Patent Owner. Thus, even if one or more of Patent Owner’s arguments as to the infeasibility of incorporating particular aspects of Gerpheide were correct, Patent Owner’s arguments do not address Gerpheide’s particular teaching of adjusting oscillator signal frequency to negate the effect of interference, and therefore, Patent Owner’s arguments are not responsive to the proposed combination and evidence relied upon by Petitioner. In view of the above, we find that Petitioner has shown that the skilled artisan would have combined Gerpheide with Ingraham/Caldwell as proposed with a reasonable expectation of success in achieving the claimed subject matter.” slip op. at 26

    “We find the ’212 Patent is directed to data for a particular user (see, e.g., ’212 Patent, Abstract). This conclusion is supported by the Specification. Indeed, all discussion in the ’212 patent is directed to a pedometer for use by and relying on data obtained from an individual user. Thus, the Specification suggests that the term “calibration” should be construed as a process that correlates a user’s stride rate and stride length. The Oral hearing confirms this conclusion. In the Oral Hearing, Petitioner’s counsel, Mr. Doshi, responded to a request to identify the calibration and the plurality of calibrations as follows: JUDGE STEPHENS: So what are you pointing at in the 212 patent as being [a] calibration and the plurality of calibrations? MR. DOSHI: That’s in column 5. So at column 5 it says that after a proper warm up the user completes a sample run or walk on the track at normal pace, et cetera, et cetera. So it's saying that here’s S1 and following completion of the first run, so here it’s saying you’re doing different walks at different speeds . . .where you're having the user walk at different walking speeds and measuring their step size as you do that (Trans. 21:1–10; see also Tr. 19:4–7) JUDGE ZADO: Okay. And then so taking that further then, I understand your argument to be that in the 212 patent the runner for the first sample S1 will run at one pace and that’s, according to Petitioner, that's one calibration and then the runner will run at a second pace for the S2 sample and that’s the second calibration, and then the runner will run at a third pace and then that's the S3 sample and then that's a third calibration? Is that Petitioner's argument? MR. DOSHI: Yes 13 (Tr. 22:4–11). Therefore, based on Petitioner’s statements at the Oral Hearing, the term “calibration” should be construed as the process of taking a sample that correlates step rate and step length for an individual.” slip op. at 13

I believe that a bachelor’s degree in one of these fields, or a similar field, with at least two years of practical experience working with pedometers and/or health or fitness trackers or sensors, or an advanced degree in one of these areas, could qualify one as a PHOSITA in this case (Ex. 2001 ¶ 26). Petitioner argues that Patent Owner’s definition of a person of ordinary skill in the art would mean a “[person having ordinary skill in the art] under Patent Owner’s definition would be more well-informed than Patent Owner’s own expert” (Pet. Reply. 2); however, we do not read Patent Owner’s assertion or Dr. Caloyannides’ testimony as suggested by Petitioner. Rather, we read Dr. Caloyannides’ testimony as expanding the fields of expertise. We do not observe a meaningful difference between the parties’ assessments of a person of ordinary skill in the art. We further note that either assessment appears consistent with the level of ordinary skill in the art at the time of the invention as reflected in the prior art in the instant proceeding (see Okajima, 261 F.3d at 1355). Our analysis in this Decision is supported by either assessment.

    “Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved (In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004)). Here, Petitioner has persuaded us that Levi is from the same field of endeavor as the ’212 Patent –– pedometers that count the number of steps taken to calculate distance traveled (see Pet. 20). Specifically, although Levi adds a navigation feature, Levi is directed to a pedometer that, in pertinent part, adjusts step size according to step frequency in order to estimate distance traveled by a user (Levi, 6:6–43). Levi states “[t]he present invention for a ground speed/distance sensor is an improvement over a common hiker’s pedometer” and “[t]he present invention analyzes the frequency of a user’s footsteps to aid in the detection of future footsteps, and further to aid in determining the size of footsteps taken by the user” (Levi, Abstract, 2:57–60, 2:65–67). Similarly, the ’212 Patent is directed to a pedometer and specifically, a pedometer that calculates actual stride lengths of a user based on relative stride rates (’212 Patent, Abstract). Thus, both the ’212 Patent and Levi are from the same field of endeavor –– pedometers or devices that include or rely on pedometers. Furthermore, both Levi and the ’212 Patent are pertinent to the particular problem with which the inventor is involved –– accurate distance identification. 44 Patent Owner additionally argues “[t]he different problems addressed” slip op. at 44

    “A holding of obviousness can be based on a showing that “there was an apparent reason to combine the known elements in the fashion claimed” (KSR Int’l v. Teleflex, Inc., 550 U.S. 398, 418 (2007)). Such a showing requires some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness. . . . [H]owever, the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ. (id. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)) (internal quotation marks omitted)). As admitted by Patent Owner, an ordinarily skilled artisan would have known a user’s stride length could vary with stride rate at the time of invention (see PO Resp. 52). As noted by Petitioner, Levi discloses using a dynamic step size algorithm that “improve[s] the accuracy of distance 49 measurements of a human footstep sensor” (Pet. Reply 25 (citing Levi, 6:17–21)). We further credit Mr. Blackadar’s testimony that an ordinarily skilled artisan would have been motivated to improve Jimenez using Levi’s dynamic step size algorithm, to improve the calculated distances (Ex. 1005 ¶¶ 92). Indeed, we find that an ordinarily skilled artisan would have been motivated to combine the teachings of Jimenez and Levi to “monitor [ ] the distance traveled more accurately than prior pedometers that calculated distance based on average stride length” (Pet. 31 (citing Ex. 1005 ¶ 90), 32 (citing Ex. 1005 ¶ 92)). In particular, we find that, given it was known a user’s stride length could vary with stride rate, as admitted by Patent Owner (PO Resp. 52), an ordinarily skilled artisan would have been motivated to implement a data processor that accounted for this relationship, such as that described in Levi (Pet. 32–33 (citing Ex. 1005 ¶¶ 93–94)).” slip op. at 49

Kent State Univ., 212 F.3d 1272, 1282 (Fed.

Apotex Inc., 754 F.3d 952, 958 (citing Schering Corp. v. Geneva Pharm., 339 F.3d 1373, 1377 (Fed. Cir. 2003)).

    “and agree with Patent Owner that the terms “re-routing the course” and “re-route the course” mean “to change at least a portion of the route of the course relative to a previous routing.” That is, there must be a first routing of a course and that routing must be changed by performance of the marine route calculation algorithm to avoid preselected conditions by identifying one or more non-user selected waypoints. The construction is consistent with the words of the claims. The claims do not merely require routing a course, but “re-routing the course.” The ordinary meaning of the prefix “re” is that something is being done again. See Tr. 18 (Petitioner agreeing that “if you put R-E in front of a word, normally that means it’s occurring a second time”). Although the claims do not explicitly recite both an original “routing” of a course that is changed by “re-routing the course,” the original “routing” is implicitly required by the use of the prefix “re.” See Tr. 34 (Patent Owner agreeing that although the claims do not explicitly require an initial routing, the initial routing is implicit in the use of “re-routing”), 44–45 (Petitioner agreeing that “re-routing” ordinarily implies an initial routing).” slip op. at 10

Claim 1, which is representative, recites that performing the marine route calculation algorithm to “route a course between a first location and the potential waypoint avoiding the preselected conditions,” where such performance includes “identifying one or more non-user selected waypoints.” Ex. 1001, claim 1. The other independent claims recite similar limitations. See Ex. 1001, claims 12, 20, 27.

    “Id. Thus, Petitioner argues that, because multiple tests must be applied to determine the continued presence of interference regardless of the source, limiting “occupied” to NFH communications systems is overly narrow. Nevertheless, the words chosen by the patentee to describe its invention have significance. In re Morris, 127 F.3d 1048, 1056 (Fed. Cir. 1997) (“It is the applicants’ burden to precisely define the invention, not the PTO’s.”). As noted above, “occupied” is only used in the Specification with respect to NFH communications systems, and neither claims 4 and 19 nor their base claims nor the intervening claims specify a single or multiple tests. Therefore, we find Petitioner’s arguments, which attempt to incorporate the teachings of “bad” and “good” channels from elsewhere in the Specification into the interpretation of these claim limitations, unpersuasive.

To the contrary, Fischer states that “[t]he communicators preferably transmit and receive messages over a wireless physical layer provided by a direct-sequence, spread spectrum (DSSS) radio data link.” Ex. 1004, 14:24–27. Fischer further explains that “[s]ince many of the signals in the coherent demodulator 114 are analog signals, the coherent demodulator 114 includes comparators to establish digital waveforms.” Ex. 1004, 16:58–60.

For example, claims 4, 14, and 19 all require a “single monolithic device.” Petitioner has shown that Fischer RF modem 96 is a single monolithic device, and that Fischer communicator 60 is a circuit contained on a single monolithic device that includes RF modem 60. See Pet. 27–28; Ex. 1003 ¶¶ 41–42. Petitioner has also shown that RF modem 96 includes coherent demodulator 114 that provides in-phase and quadrature data outputs that are responsive to an analog signal that has in-phase and quadrature components, corresponding to the requirements of an analog signal “in the form of in-phase and quadrature components” as recited in claims 5 and 16. See Pet. 28–29; Ex. 1003 ¶ 38. With respect to the limitations of claims 6, 16, and 20 requiring PN modulation and phase shift keyed modulation, Petitioner has shown that Fischer discloses RF modem 96 supports BPSK or QPSK, and that it would have been obvious to implement direct sequence spread modulation by using PN modulation.

Thus, we find Patent Owner’s contention that those of skill “would not look beyond the teachings of Fischer” unpersuasive. See id. Likewise, Patent Owner’s contention that Fischer already teaches improved reliability by using longer preambles has no bearing on whether one of ordinary skill in the art would have also looked to Nakamura for other means of improving reliability. See id. at 39. We find that Petitioner articulates sufficient reasoning with rational underpinnings. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (cited with approval in KSR Int’l. Co. v. Teleflex, Inc., 550 U.S. 398, 418 (2007)).” slip op. at 28

  • Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Decided for petitioner

    “implemented function is the algorithm disclosed in the specification.” Aristocrat Techs. Austl. Party Ltd. vs. Int’l Game Tech., 521 F.3d 1328, 1333 (Fed. Cir. 2008) (quoting Harris Corp. v. Ericsson Inc., 417 F.3d 1241, 1249 (Fed. Cir. 2005)). Additionally, specific portions of the specification must clearly link or associate a computer program or algorithm to the function corresponding to the claimed means. See Medical Inst. and Diag. Corp. v. Elektra AB, 344 F.3d 1205, 1211 (Fed. Cir. 2003). For the reasons set forth below, we conclude that the four steps and other ’604 patent specification portions identified by Enfish do not describe an algorithm for the recited function of “configuring memory according to a logical table.” We further conclude that Enfish has not clearly linked or associated the recited function to the four steps or the other portions of the ’604 patent specification that Enfish identifies.” slip op. at 11

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

    “We determine that adopting Enfish’s proposed construction without further context would create ambiguity. Additionally, limitations are not to be read into the claims from embodiments in the specification. See In re Van Geuns, 988 F.2d 1181 at 1184. Furthermore, we agree with Microsoft that Enfish relies on insufficient extrinsic evidence for support, for example, that an OID is “immutable.” We also note that Enfish’s contentions are not commensurate with the scope of the claims because each of the independent claims recites that an OID is included “to identify” each logical row and each logical column, but does not recite using an OID to retrieve data from memory. We, therefore, determine that the construction of “OID” in the Decision to Institute should not be changed.” slip op. at 18

    “We give little weight to Dr. Hosking’s testimony with respect to the limitations in claim 34 because he does not provide an explanation or evidence as to why Dickerson’s synchronization of data in the same column across separate databases teaches reciprocal synchronization between columns in the same table. Dr. Hosking states that a person of skill in the art would be motivated to combine Chang and “the synchronization concept as taught in Dickerson in the case that similar elements were to be reciprocally synchronized.” Ex. 1022 ¶ 225. The premise of this argument is the assumption that Dickerson’s synchronization across separate databases is the same as synchronizing two logical columns reciprocally in the same database table. Dr. Hosking does not provide support for this assumption. This argument, therefore, does not sufficiently explain why mirroring data across separate databases leads to data synchronization between logical columns in the same table. Dr. Hosking’s testimony does not explain why, or how, one of ordinary skill in the art would use the database management disclosed by Chang in cooperation with the linked database elements between separate databases to achieve reciprocal synchronization “to achieve such coordination of the data” between logical columns in the same table. See id. at ¶¶ 283–294.” slip op. at 41
