    “4. Summary In view of the foregoing, we determine that Petitioner has not demonstrated a reasonable likelihood of showing that independent claims 1, 8, and 16 would have been obvious over Rockwood and Xie. Claims 2–7, 9–15, and 17–19 depend from claims 1, 8, or 16. Accordingly, we also determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on its assertion as to these dependent claims. IV. CONCLUSION For the foregoing reasons, Petitioner has not demonstrated on the record before us a reasonable likelihood that it would prevail in showing the unpatentability of any of the challenged claims of the ’045 patent. Therefore, we do not institute trial.10 V. ORDER For the reasons given, it is ORDERED that the Petition is denied and no trial is instituted.” slip op. at 23

See Pet. 17–18. We further find that Petitioner does not adequately describe how these references might be combined. Rockwood describes a system that identifies attacks at a network edge as they occur,8 whereas Xie’s system looks for similar changes across different hosts within a network over multiple days.

  • Expert testimonyPatent owner expert discountedDecided for petitioner

    “Mr. Occhiogrosso made similarly inconsistent statements on this point on cross-examination. For example, when asked whether the claim requires that the “content-descriptor file be a different file,” Mr. Occhiogrosso responded that “[i]n my opinion, there’s nothing inherent that says it has to be stored in the same physical data file on the same storage medium.” Ex. 1057, 68:11–23. But when asked, “Could the content-descriptor file be one of the web pages that make up a website?” he responded, “In my opinion, no.” Id. at 70:9–13. Notwithstanding such inconsistent statements, we find that, taken as a whole, Mr. Occhiogrosso’s testimony reflects an opinion contrary to that of Mr. Lipoff, namely the recited “content-descriptor file” must be a file separate and distinct from an HTML web page. The Federal Circuit has “viewed extrinsic evidence in general as less reliable than the patent and its prosecution history in determining how to read claim terms,” e.g., because expert testimony “is generated at the time of and for the purpose of litigation and thus can suffer from bias that is not present in intrinsic evidence.” Phillips, 415 F.3d at 1318. In this instance, although we discern certain (but contrary) positions in the experts’ opinions on this point, the inconsistencies in their cross-examination testimony limit our confidence in those opinions. We accordingly give greater weight to the intrinsic evidence, which more strongly supports Petitioner’s position. We accordingly determine that Petitioner’s showing with respect to this limitation is sufficient.” slip op. at 39

    “Patent Owner disputes Petitioner’s reasoning because Petitioner’s “motivation to combine argument is centered on the periodic retrieval of information from an information source (webpage) and not on an information source that is periodically updated,” as the claim recites. PO Resp. 24. Nevertheless, Patent Owner concedes that Petitioner “establishes . . . that the Wise website information sources are periodically updated,” which Petitioner correctly observes “is all that the claim requires.” Id.; Reply 9. Patent Owner reasons that there is no motivation to combine teachings from the two references because “the Wise system alone already provides the most up-to-date and complete information to the user.” PO Resp. 27. But the Federal Circuit has criticized such an argument as “reasoning [that] belies its conclusion”: “[t]hat [two prior art references] address the same problem and that [one of the references] was a known way to address that problem is precisely the reason that there’s a motivation to combine under KSR and [Federal Circuit] precedent.” Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380 (Fed. Cir. 2023) (quoted in Pet. 10– 11). This is the “known-technique” rationale, in which “[t]here is a motivation to combine when a known technique ‘has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way.” Id. at 1380–1381 (citing KSR, 550 U.S. at 417). Implementing periodic updating of information sources as taught by Dasan would be within the skill of an ordinary artisan to implement in Wise’s system.

    “We disagree with Petitioner’s interpretation. Taking Petitioner’s point that “‘specified data rate’ means only that the data rate is specified in some way” (Pet. Reply 4), we do not see how, once the rate is specified, claim 1’s later recitations of “the specified data rate” could refer to any other rate, as Petitioner’s arguments suggest. Petitioner argues that “it is clear that the ‘specified data rate’ that provides antecedent basis for later recitations of that term is merely the data rate specified for ‘communicat[ing] data’ between the ‘memory module’ and the external ‘memory controller of the computer (alteration by Petitioner). We agree with this statement, and later recitations of “the specified data rate,” therefore, refer to the data rate that is so specified.

    “PO Resp. 19; see also Ex. 2003 ¶¶ 68–72 (Dr. Przybylski’s testimony explaining this annotated figure). Halbert’s Figure 5 is a timing diagram for two consecutive read operations (Ex. 1005 ¶¶ 16, 37), and Patent Owner includes annotations to show each of ranks 140 and 142 outputting data onto their respective data busses at half the rate that data are output from data interface circuit 120 on the DQ data line. In particular, Halbert explains that each of ranks 140 and 142 is “capable of performing m-bit-wide data transfers.” Ex. 1005 ¶ 30. On a read command, rank 140 sends m-bit-wide data to bi-directional data register 126 on line RDQ0 at the same time that rank 142 sends m-bit-wide data to bi-directional data register 128 on line RDQ1, as shown in Figure 5 between T7n and T8n. Ex. 1005 ¶¶ 31–32, 39. Halbert discloses that register 126 or from register 128 to output to buffer 122, which are then output on line DQ. Ex. 1005 ¶ 33. Halbert explains that “[d]ata is serialized from the data registers onto the memory data bus by reading 2m bits into the data registers during one memory device read cycle, and then driving these bits, m at a time, through MUX 124.” Ex. 1005 ¶ 33. As shown in Halbert’s Figure 5, over one clock cycle (T7n–T8n), each of ranks 140 and 142 outputs one piece of m-bit-wide data, and over one clock cycle (T8–T9), those two pieces of m-bit-wide data are output on line DQ to the system memory data bus. Halbert explains that the second read operation proceeds in the same fashion as the first and that “[t]he net result is that the memory data bus transfers 4m bits of data in two memory bus clock cycles (four mbit transfers), with only two data accesses performed at each memory device on the module.” Ex. 1005 ¶ 42. Thus, Halbert’s memory module outputs data to the system memory data bus at twice the rate that each of ranks 140 and 142 outputs data.

    “strength indicator circuits 440 and 450, the written description unambiguously discloses that each circuit determines the cumulative signal level of the desired signal and the interfering signals. Neither circuit determines only the signal strength of the interferer signals, nor does a circuit determine only the signal strength of the desired signal. In other words, the written description does not support a limited reading of the claim language so as to require two separate circuits—one circuit for determining a a signal strength of the desired signal. Thus, based on this preliminary record, we do not construe the circuit limitation as requiring the wireless transceiver necessarily to have two circuits, one circuit for determining a signal strength of the interferer signal and a different circuit for determining a signal strength of the desired signal, because, under that reading of the claim, the only embodiment in the written description would not fall within the scope of the claim.

    “As explained above, however, on this preliminary record, we do not interpret the circuit limitation to impose a timing requirement such that the determining has to occur at precisely the same time. Nor at this preliminary juncture do we read a precise timing requirement into the circuit limitation based on written description disclosure that the desired signal and the interferer signal are part of the received signal input spectrum. As explained above, for example, the written description describes a circuit providing a cumulative signal level corresponding to the sum of the desired and interfering signals. Ex. 1001, 6:59–67. As such, the written description describes making the determinations on two signals that are part of the received signal input spectrum. Patent Owner argues that Rauhala does not disclose “two determinations of two different signal strengths together.” Prelim. Resp. 40. We do not agree with Patent Owner on this preliminary record. Rauhala’s disclosure of providing control bits based on the comparisons of the signal strengths to respective thresholds, discussed above, also undermines Patent Owner’s argument that detector DET, which (i) provides one or the other and (ii) needs to be re-tuned to read the other signal, cannot anticipate the claim. Notably, for example, Rauhala discloses setting control bits based on comparisons of the respective signal strengths to thresholds: cM. Signal cA is 0 when signal RSS is greater than S4 and signal RSSn is at the same time smaller than Sn. Otherwise, signal cA is 1. Signal cA is taken to amplifiers Al and A2. Signal cM is 1 when signal RSS is not greater than S4 and signal RSSn is at the same time at least Sn. Ex. 1004 ¶ 17 (emphases added).

Petitioner treats this requirement as having two aspects, namely (1) whether a person of ordinary skill could reasonably have found RemoteCentral.com and (2) whether such a skilled artisan could reasonably have found RadioShack on RemoteCentral.com. Reply 8–13; see also Tr. 33:25–34:8 (Patent Owner asserting that there are two aspects to the analysis on public accessibility: “The first is whether a [person of ordinary skill in the art] would have known to arrive at the website containing the prior art reference. The second one is . . . , [a]ssuming the [person of ordinary skill in the art] would have done so, would the [person of ordinary skill in the art], exercising reasonable diligence, have located the prior art reference on the site?

    “addressed squarely by the principles set forth in Hulu, which addresses the standards at the institution stage and during the trial for evaluating evidence proffered to show asserted art qualifies as a printed publication. Specifically, after a petitioner has presented “evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent,” such that trial is instituted, “some limited opportunities exist for the petitioner to present new evidence later.” Hulu at 13–14. These “limited opportunities” include “in a reply to the patent owner response,” provided that the additional evidence is “responsive to the prior briefing” and provided that the additional evidence does not require “completely reopen[ing] the record, by, for example, changing theories after filing a petition.” Id. at 14–15. Although Patent Owner contends that “[t]his is not an example of permissible rebuttal evidence, but rather a belated attempt to fill a gap in the evidence in the Petition,” we disagree. See Sur-reply 6. Rather, the 7 Patent Owner appears to refer incorrectly to Exhibit 1040 instead of Exhibit 1041 when identifying “articles allegedly referring to RemoteCentral.com.” See Sur-reply 5–6. progression within the instant proceeding comports well with the Hulu framework. During the preliminary proceeding, Petitioner came forth with “evidence sufficient to establish a reasonable likelihood that [RadioShack] was publicly accessible before the critical date of the challenged patent,” just as Hulu demands. Hulu at 13; Inst. Dec. 23 (“[W]e determine that Petitioner’s showing regarding public accessibility of RadioShack is sufficient under the standard we apply at this stage of the proceeding.”). Patent Owner challenges RadioShack’s status as a printed publication in its Response, just as Hulu contemplates. Hulu at 15; PO Resp. 28–41. And Petitioner submits additional evidence that replies to that challenge without changing its theory that RadioShack qualifies as a printed publication by virtue of its accessibility on the RemoteCentral.com web site and in light of date indicia on RadioShack itself.8 See Hulu at 15–16; Reply 7–13. Moreover, in determining that Petitioner’s additional evidence directed at RemoteCentral.com is properly considered, we are further mindful of the Federal Circuit’s endorsement that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1830–81 (Fed. 8 In its Reply, Petitioner also relies on evidence of publication of RadioShack on Radio Shack’s own public website and on “a third location,” hifi-remote.com. Reply 14. As we discuss below, we determine that the presence of RadioShack on RemoteCentral.com is sufficient to qualify RadioShack as a printed publication. We therefore do not reach the issue of whether presence on either the Radio Shack web site or on hifi-remote.com is an improper new theory raised by Petitioner in its Reply. See Tr. 8:13– 9:23 (Petitioner discussing whether reliance on hifi-remote.com presents a different theory than set forth in the Petition). Cir. 2018); see also Vidstream LLC v. Twitter, Inc., 981 F.3d 1060, 1065 (Fed.

We conclude that the Board acted appropriately, for the Board permitted both sides to provide evidence concerning the reference date of the Bradford book, in pursuit of the correct answer.”). We accordingly give due weight to Petitioner’s additional evidence of RadioShack’s accessibility on the RemoteCentral.com web site.” slip op. at 25

As explained below, we do not reach the predicate position upon which the objections are based. See Tr. 5:8–11 (Petitioner stating that “this Board only needs to resolve this objection if it accepts Roku’s claim construction argument that the claims cover a press and hold of a single button, but that they do not cover pressing multiple buttons to present that argument in the alternative.

    “We disagree with Patent Owner’s arguments because, as Petitioner points out, the evidence shows that DDR3 devices do not always have edge-aligned data and strobes. See Pet. Reply 4. In particular, Patent Owner’s declarant Dr. Mangione-Smith testifies that the DDR3 standard allows a 200 picosecond maximum DQS-to-DQ skew, “which is a very tight tolerance considering the speed at which the memory devices are operating.” Ex. 2006 ¶¶ 122–125 (citing Ex. 1020, 164). During cross-examination of Dr. Mangione-Smith, Petitioner established that a 200 picosecond tolerance is actually a misalignment of over 28 degrees considering the 2.5 Pet. Reply 4 (discussing this testimony). Thus, the evidence shows that DDR3 data and strobes are not always edge-aligned. Patent Owner dismisses this, stating that “Petitioner’s argument is tantamount to saying that the JEDEC standard prescribes a tolerance for DQS/DQ skew that causes errors, which runs counter to the entire standard-setting process.” PO Sur-reply 3–4. On the contrary, we find that Petitioner’s showing underscores that Butt’s read training has direct applicability to a memory that may potentially skew by as much as 28 degrees. Butt explains that read training is used “to establish optimum DQS strobe settings” and thereby “enables a reliable data read operation for high speed applications.” Ex. 1029 ¶¶ 33, 36; see Pet. 44–47 (discussing this disclosure). As the Supreme Court has stated, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. “This is the so-called ‘known-technique’ rationale. And if there’s a known technique to address a known problem using ‘prior art elements according to their established functions,’ then there is a motivation to combine.” Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380 (Fed. Cir. 2023) (citing Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 799–800 (Fed. Cir. 2021)). We find that Butt’s read training is such a known technique that would improve Hiraishi’s memory based on the benefits identified in Butt and discussed above, i.e., “establish[ing] optimum DQS strobe settings” to enable “reliable data read operation for high speed applications.” Ex. 1029 ¶¶ 33, 36. timing operation” to account for flight time differences between memory devices, pointing to Hiraishi’s retiming operation that is performed after the data are loaded in FIFO (Read) circuit 302. PO Resp. 45 (citing Ex. 1005 ¶ 130). But Petitioner’s obviousness contentions are based on adjusting the timing of strobes before the data are registered in (loaded into) FIFO (Read) circuit 302. See Pet. 35–37 (asserting that the delayed read strobe is “the DQS signal supplied to FIFO (Read) circuit 302,” which is then used to register the data in FIFO (Read) circuit 302). Thus, Patent Owner is pointing to an entirely different operation. Furthermore, even if Hiraishi discloses some mechanism to cope with misaligned data and strobes, we find that Butt’s technique is a “suitable option” in combination with Hiraishi. See Intel, 61 F.4th at 1381. Indeed, in such a case, Hiraishi and Butt “address the same problem,” and Butt’s read training “was a known way to address that problem[, which] is precisely the reason that there’s a motivation to combine under KSR and [Federal Circuit] precedent.” Intel, 61 F.4th at 1380. Thus, it is not necessary for Petitioner to “identify what details are allegedly missing from Hiraishi which are being provided by Butt,” as asserted by Patent Owner.
