      “C. Legal Principles 1. Anticipation A patent claim is unpatentable under 35 U.S.C. § 102 if “the four corners of a single, prior art document describe every element of the claimed invention, either expressly or inherently, such that a person of ordinary skill in the art could practice the invention without undue experimentation.” Advanced Display Sys., Inc. v. Kent State Univ., 212 F.3d 1272, 1282 (Fed. Cir. 2000). “A single prior art reference may anticipate without disclosing a feature of the claimed invention if such feature is necessarily present, or inherent, in that reference.” Allergan, Inc. v. Apotex Inc., 754 F.3d 952, 958 (citing Schering Corp. v. Geneva Pharm., 339 F.3d 1373, 1377 (Fed. Cir. 2003)). Moreover, the reference must also “disclose[] within the four corners of the document not only all of the limitations claimed but also all of the limitations arranged or combined in the same way as recited in the claim.” Net MoneyIN, Inc. v. Verisign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008). However, “the reference need not satisfy an ipsissimis verbis test.” In re Gleave, 560 F.3d 1331, 1334 (Fed. Cir. 2009). We analyze the ground based on anticipation in accordance with the above-stated principles.” slip op. at 22

      “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

      “proposed construction of “course” as “the path of intended travel of a craft with respect to the earth.” Instead, we need only focus on the words recited in the claim. 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. Based on the limitation recited in the claim, the broadest reasonable interpretation of routing a “course” encompasses the identification of one or more non-user selected waypoints between a first location and a potential waypoint. No further construction is necessary for purposes of this Decision.” slip op. at 17

      “We are persuaded by Petitioner’s argument that the person of ordinary skill in the art need not have first-hand experience with marine navigation devices and systems. Pet. Reply 25–26. The ’703 patent explicitly defines “marine navigation” broadly, noting that “the use of the word ‘marine’ in the embodiments of the present invention (including the claims) could be replaced with the phrase ‘non-street based.’” Ex. 1001, 1:57–67 (emphasis added). Such non-street based navigation is broad enough to encompass avionic navigation. See Pet. Reply 25–26; cf. Ex. 1003, 4–7 (demonstrating Dr. Braasch’s experience in avionic navigation). We find that Petitioner’s definition is supported by the testimony of its expert, Dr. Braasch, and, for the reasons stated above, we are not persuaded that the person of ordinary skill in the art necessarily would have had first-hand experience in marine—as opposed to non-street based— navigation. We, therefore, determine, based on the complete record, that Petitioner’s proposed definition correctly states the level of ordinary skill in the art, and we apply it for purposes of this Decision.7, 8” slip op. at 24

      “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. See Intervet America, Inc. v. Kee-Vet Laboratories, Inc., 887 F.2d 1050, 1053 (Fed.

      “Petitioner also provides a persuasive rationale for combining the teachings of Dabak and Kockmann. Id. at 39–40. Petitioner asserts that they are both references directed to the same problem, namely, “to communication performance improvements through adapted frequency hopping to avoid channels disturbed by interference.” Id. at 40 (citing Dabak, Abstract; Kockmann, 2:49–3:20; 620 Ex. 1002 ¶ 113). In addition, according to Petitioner, a person of ordinary skill in the art would have had reason to modify the teachings of Dabak regarding the MSD technique in view of the teachings of Kockmann “to utilize multiple channels to communicate with the slave device over the subset of communication channels according to an adapted hopping sequence” in order to accomplish the shared goals of these references. Id. at 40 (citing 620 Ex. 1002 ¶ 113); see In re Ethicon, Inc., 844 F.3d 1344, 1351 (Fed. Cir. 2017) (“The normal desire of artisans to improve upon what is already generally known can provide the motivation to optimize variables such as the percentage of a known polymer for use in a known device.”). According to Petitioner, the combination of these teachings “is a simple use of known teachings to yield predictable results.” Id. (citing KSR, 550 U.S. at 416 (“The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.”)). Based on our review of Petitioner’s arguments and evidence, we find that Petitioner demonstrates that combined teachings of Dabak and Kockmann teach or suggest all of the limitations of independent claims 1 and 16 and find that a person of ordinary skill in the art would have had reason to combine the teachings of Dabak and Kockmann to achieve the methods of claim 1 and the devices of claim 16. See 620 Pet. 17–20, 33–35, 38–40, 48–49. We conclude that Petitioner has shown by a preponderance of the evidence that independent claim 1 would have been obvious over the combined teachings of Dabak and Kockmann. Moreover, because Petitioner’s arguments for the obviousness of independent claim 16 over Dabak and Kockmann rely on the arguments and evidence presented with respect to independent claim 1, we also conclude that Petitioner has shown by a preponderance of the evidence that independent claim 16 would have been obvious over the combined teachings of Dabak and Kockmann, as well as on its related challenges to dependent claims 2, 3, 5, 8, 9, 12, 14, 15, 17, 18, 20, 23, 24, 27, and 29–31.

      “Patent Owner contends, however, that the combined teachings of Dabak and Kockmann fail to teach or suggest all of the limitations of claim 4. In particular, Patent Owner contends that, “[a]s described in Kockmann, ‘disturbed’ does not in fact mean ‘occupied,’ but rather it only means that ‘[a] disturbed carrier frequency is thus a carrier frequency onto which a signal is modulated that exceeds a specific threshold.’” PO Resp. 14 (citing Kockmann, 6:43–49). Patent Owner contends that determining whether a channel is “occupied” “requires analysis beyond the measurements called for by Kockmann (i.e.[,] determining more than just the mere presence of a modulated signal ‘that exceeds a specific threshold,’ but rather whether its source was FH or NFH).” Id. at 15; see 620 Ex. 2001 ¶¶ 33–37. Initially, Petitioner again states that Kockmann discloses that “[d]isturbance thereby means that either a disturbance in the actual sense or an occupancy by some other transmitter is present.” Kockmann, 6:41–43 (emphasis added). Patent Owner contends, however, “that a channel ‘occupied’ by an NFH system and a channel ‘disturbed’ by another transmitter are somehow different because an occupancy determination requires additional ‘analysis.’” Reply 10. Nevertheless, we agree with Petitioner that Patent Owner does not show where the claims recite one type of analysis or prohibit another. Id. Thus, we find that the combined teachings of Dabak and Kockmann teach or suggest all of the limitations of claim 4. Petitioner’s arguments with respect to claim 4 apply equally to claim 19. Based on our review of the arguments and evidence, we conclude that Petitioner has established by a preponderance of the evidence that claims 4 and 19 would have been obvious over the combined teachings of Dabak and Kockmann.” slip op. at 34

      “Second, Dr. Wolfe testified that Matsumiya discloses “a shaft” that protrudes from each side of the case. Ex. 1016 ¶ 97. On cross-examination, however, Dr. Wolfe admitted that while Matsumiya could disclose a “split axle,” “normally, you’d presume that it’s a through axle.” Ex. 2012, 85:9– 18. Dr. Wolfe did not explain in his direct testimony how either an axle or split axle would be integrated with or attached to at least one side of the case. Third, Petitioner relied on the express disclosure of Matsumiya, not a modification of Matsumiya, as teaching this element of the claims. See Pet. 16 (relying only on Matsumiya’s disclosure). In its Reply, Petitioner asserts, for the first time, that Matsumiya “could also use a snap hinge,” pointing to Professor Visser’s cross-examination testimony. Reply 13 (citing Ex. 1050, 127:9–11). Professor Visser’s testimony, however, does not support Petitioner’s argument. Professor Visser testified that Matsumiya does not show a snap-on hinge, and that a snap-on hinge would not have the same functionality as an axle. Ex. 1050, 127:18–21. He also testified that the two concentric rings on the arms of Matsumiya are inconsistent with a snap-on hinge. Id. at 128:17–20. Thus, the issue before us is not whether it would have been obvious to modify Matsumiya to include a snap-on hinge or hinge protuberance on the side of the case because that was not the basis set forth in the Petition and upon which we instituted review; rather, the issue is whether Petitioner has shown that Matsumiya discloses a hinge element or hinge protuberance integrated with or attached to at least one side of the case. In light of the record before us, and as detailed in the discussion above, we conclude that Petitioner has not shown that Matsumiya discloses a hinge element or a hinge protuberance “formed on at least one side of the case.” We find that Petitioner has failed to present sufficient evidence to show that Matsumiya discloses this element of the claims, and we find Patent Owner’s evidence in the form of Dr. Wolfe’s cross-examination testimony and Professor Visser’s testimony more persuasive.” slip op. at 22

The ’544 patent states that “[t]he present invention relates to a flash memory apparatus, and more particularly to a flash memory apparatus, wherein a cover is not completely separated from the main body upon being in use so that lost [sic] of the cover is prevented.” Ex. 1001, 1:8–11. The ’544 patent is largely directed to a cover that rotates with respect to a case (as is evident from the parties’, and consequently our, extensive discussion of the hinged connection (i.e., hinge protuberances and hinge holes)), but is not readily disconnected. In fact, the ’544 patent discloses the recited “hooking groove” and “hooking threshold” specifically to prevent the hinge hole from being easily detached from the hinge protuberance. Id. at 3:36–43 (“Furthermore, a hooking groove 34 is preferably formed on the lower periphery of the hinge protuberance 33. A hooking threshold 45 is hooked on the hooking groove 34 and is preferably formed on a rim confining the hinge hole 41 in order to prevent the hinge hole 41 from being easily detached from the hinge protuberance 33 after joining of the hinge hole 41 and the hinge protuberance 33.”).

Rather, from our review the record supports that Matsumiya’s cover is securely attached to the case. Additionally, we are unaware of any teaching in Matsumiya of disconnecting the cover from the case. Similarly, the ’544 patent aims to avoid disconnecting the cover from the case, as discussed above.

      “Fischer teaches that the comparators in coherent demodulator 114 convert a “‘spread spectrum modulated’ analog signal into a digital signal,” as opposed to “other analog signals.” See PO Resp. 13. 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. As shown in Figure 5 of Fischer, the coherent demodulator 114 is followed by spread spectrum correlator and decoder 130, which “handles the demodulator 114 output to regenerate the unspread data.” Ex. 1004, 17:58– 60. Thus, we agree with Petitioner, as supported by Prof. Ding, that a person of ordinary skill in the art “would have understood Fischer to describe that the demodulator 114 converts the analog DSSS modulated messages received by antennas 100/102 to digital signals and outputs these digital DSSS modulated messages in I and Q format to spread spectrum correlator and decoder 130.” Reply 3–4; Ex. 1013 ¶ 5.” slip op. at 18

      “The Petition makes no mention of Nakamura in its discussion of the additional limitations of claims 2 and 11. Yet in reply, Petitioner argues that “[i]n view of Fischer’s variable length preambles, a [person of ordinary skill in the art] would have found it obvious to utilize Nakamura’s timer function and its repetitive duration function.” Reply 15. Petitioner may not rely on a new argument asserting that Nakamura teaches the additional limitations for claims 2 and 11 presented for the first time in its Reply. Moreover, Petitioner fails to address how either Fischer or Nakamura teaches means for adjusting means for timing when Fischer contains no timer, and when the timer of Nakamura is described as being based on a predetermined period of time. See Ex. 1005, 6:31–36 (“timer 34 permits the switch 14 to transfer from terminal A to terminal B after the lapse of predetermined time”); see also Ex. 2006, ¶¶ 83–84. Petitioner’s contention that “Nakamura’s timer is also flexible” is insufficiently supported by any reference to either Nakamura or the declaration of Prof. Ding. See Reply 16–17; see also Ex. 1013 (no discussion of claims 2 or 11). Petitioner has not demonstrated that the features of claims 2 or 11 are disclosed by the combination of Fischer and Nakamura. 5. Claims 4, 5, 6, 13, 14, 16, and 18–20 Petitioner has persuasively shown that each of the additional limitations of dependent claims 4, 5, 6, 13, 14, 16, and 18–20 are taught by the combination of Fischer and Nakamura. 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. See Pet. 29; Ex. 1003 ¶¶ 34, 37. We are also persuaded that Fischer discloses the “antenna selection circuitry” as recited in claim 13 and the “serial data stream” as recited in claim 18.

      “Patent Owner contends that “[i]f reliability alone is the concern,” then “the most reliable method is to use BPSK for the entire packet (as taught by Fischer).” PO Resp. 38. We are not, however, persuaded that “reliability alone is the concern.” Nakamura and Fischer clearly teach a benefit to using both BPSK and QPSK consisting of improved reliability for BPSK with enhanced speed from QPSK. 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.

      “the art “would have appreciated the benefit of including multi-carrier modulation in the Wu system” because “Wu itself references the 802.11a standard as a multi-carrier OFDM scheme that is able to achieve data rates that are faster than the 802.11b transmission rates used in the Wu system.” Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68; Ex. 1108, 411). Petitioner contends that [w]ith this motivation in mind a [person of ordinary skill in the art] would have recognized that adding the multi-carrier 802.11a modulation scheme to the modulation schemes already available in the Wu system would have been a simple addition, if a technique was available for using a channel estimate obtained from data modulated according to a single carrier modulation scheme for acquisition of data modulated according to a multi-carrier modulation scheme[,] and supports that contention with testimony by Dr. Almeroth. Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68). Petitioner identifies such a technique as disclosed by Böhnke. Id. at 49. Böhnke “relates to the mapping of data and pilot symbols in an OFDM-system.” Ex. 1113, col. 1, ll. 4–5. Figure 2 of Böhnke is reproduced below. Figure 2 illustrates a sequence that includes a first OFDM modulated signal S1, a midamble MA that can be OFDM modulated or single-carrier modulated, and a second OFDM symbol S2. Id. at col. 4, ll. 36–41. The midamble can be used for the transmission of pilot symbols, which “are necessary for a channel estimation such as to effect coherent detection of e.g. OFDM-modulated signals,” and such pilot symbols can be created by a single carrier modulation with a known training sequence. Id. col. 1, ll. 7–9, col. 5, ll. 45–49, col. 5, ll. 61–63. Böhnke, thus, uses the channel estimation obtained from the single-carrier training sequence to detect multi-carrier OFDM symbols by matching bandwidth and performing synchronization. Id. at col. 2, ll. 43–45, col. 2, ll. 61–62. Petitioner reasons that the Böhnke channel-estimation techniques “provide a way to combine a high-rate, multicarrier OFDM data transmission scheme with a single carrier training sequence” and that [w]ith this background, a [person of ordinary skill in the art] investigating options for including the multi-carrier 802.11a standard in the Wu system would have appreciated that Bohnke’s channel estimation techniques could be applied to Wu’s single-carrier 802.11b preamble and used for acquisition of data modulated according to multi-carrier 802.11a.” slip op. at 12

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 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.
