“B. Anticipation by Shinohara A claim is anticipated if each limitation of the claim is disclosed in a single prior art reference arranged as in the claim. Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1369 (Fed. Cir. 2008). As recently reiterated by the Federal Circuit, “a reference can anticipate a claim even if it ‘d[oes] not expressly spell out’ all the limitations arranged or combined as in the claim, if a person of skill in the art, reading the reference, would ‘at once envisage’ the claimed arrangement or combination.” Kennametal, Inc. v.

- Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner
“the ’176 grandparent application is insufficient. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” Lockwood v. Am. Airlines Inc., 107 F.3d 1565, 1571–72 (Fed. Cir. 1997); see also Reply 5–6. We find that the cited disclosures in the ’176 grandparent application do not describe the density, size, depth, or height of the deformities at approximate midpoints between adjacent pairs of light sources. As discussed above, Patent Owner maintains that a skilled artisan reading the ’176 grandparent application would know that “the approximate midpoint between the two light sources is an area farther away from a light source.” PO Resp. 28 (emphasis added). We are not persuaded by this argument, for it does not establish that the approximate midpoint between adjacent pairs of light sources is the only area farther away from a light source. As Petitioner points out, “the increased distance from the light source is not limited to a distance along the length of the panel member, along the width of the panel member, or along any direction at all.” Reply 11. Thus, Patent Owner fails to meet its burden under Dynamic Drinkware, LLC v. National Graphics, Inc., 800 F.3d 1375, 1379–80 (Fed.

“In view of the foregoing, we determine that Patent Owner has not demonstrated that the ’176 grandparent application, as originally filed, provides written description support for the disputed limitation. Therefore, we determine that claims 1–5 are not entitled to the benefit of the filing date of the ’176 grandparent application and Patent Owner is thus entitled only to the effective filing date of the application for the ʼ973 patent, February 9, 2007. As a consequence, we find that Shinohara qualifies as prior art.” slip op. at 11

“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

“Id. at 1:14–23. Accordingly, we find that Kindig’s field of endeavor is hinged enclosures to house appliances that make noise when operated. 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.”). Thus, we find that the ’544 patent’s field of endeavor is hinge assemblies for a flash memory apparatus.” slip op. at 32

“Second, Petitioner asserts that Kindig’s hinge connection “would advantageously help to retain connection between the cover of Matsumiya and the memory card,” id. at 25, but Petitioner has not shown that Matsumiya fails to retain the connection between case and cover or has difficulty doing so. 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. Kindig, however, is directed to an easily detachable cover. Accordingly, Petitioner’s reason—as to why one of ordinary skill in the art would have been prompted to modify Matsumiya by adding the elements of claim 13 from Kindig—lacks a rational underpinning. 3.

“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. See Pet. 30–31; Ex. 1003 ¶ 40. Patent Owner does not substantively dispute Petitioner’s assertion that Fischer teaches each of these limitations.” slip op. at 25

“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.

“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

“We agree with Patent Owner that Petitioner’s analysis of claim 22, which recites separate single-carrier and multi-carrier receivers, as well as a switch coupled to such receivers, is deficient. Petitioner’s assertion that claim 22 is unpatentable for “reasons similar to those explained in regards to claims 1-3 and 5” insufficiently addresses these limitations, which do not appear in claims 1–3 or 5. Pet. 58.” slip op. at 23
