“person of ordinary skill in the art requires knowledge in “the field of home and business security,” Petitioner’s expert, Bruce McNair, testifies that he has designed and installed home security, sensor, and alarm systems. Ex. 1003 ¶ 12. Also, Mr. McNair’s experience with wireless communication and cryptographic security systems is also relevant (see, e.g., id. ¶ 10) even if it involved more complex systems because, “to be qualified to offer expert testimony on issues from the vantage point of an ordinarily skilled artisan in a patent case, an expert must at a minimum possess ordinary skill in the art.” Kyocera, 22 F.4th at 1377–78 (emphasis added). Thus, on this record, we disagree with Patent Owner’s argument Petitioner has failed to support its Petition with the testimony of someone who possesses the knowledge and skill at least of an ordinarily skilled artisan—even under Patent Owner’s definition. See Prelim. Resp. 49.” slip op. at 6

“Patent Owner does not provide a different assessment of the level of ordinary skill, but Dr. Przybylski states that an individual with the level of experience identified by Petitioner “would have less knowledge and familiarity” than presumed by Petitioner’s definition. Ex. 2003 ¶ 46. Dr. Przybylski, however, provides no further discussion explaining this apparent disagreement with Petitioner, nor does he set forth what level of knowledge and familiarity a person of ordinary skill in the art would have had. Based on the complete trial record, we determine that Petitioner’s proposed skill level is consistent with the level of ordinary skill evidenced by the ’314 patent and the asserted prior art, and we adopt that skill level with the exception of the phrases “at least,” which introduce vagueness as to the amount of experience.” slip op. at 6

“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. Petitioner provides no persuasive argument to support its position that later recitations of “the specified data rate” could be satisfied by data rates that are not the “specified data rate.”” slip op. at 7

“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. See Ex. 2003 ¶¶ 68–73 (Dr. Przybylski’s credible testimony explaining Halbert’s data rates).” slip op. at 11

“disseminated to the interested public, ‘public accessibility’ has been called the touch-stone in determining whether a reference constitutes a ‘printed publication’ . . . .” Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347, 1356 (Fed. Cir. 2018) (quoting In re Hall, 781 F.2d 897, 898–99 (Fed. Cir. 1986)). A reference is considered “publicly accessible” if it was “disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, can locate it.” Id. at 1355–56 (citing In re Wyer, 655 F.2d 221, 226 (CCPA 1981)).

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.

“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.

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. See PO Resp. 44.” slip op. at 14

“For the reasons discussed above and based on Petitioner’s contentions and evidence, we find that the combination of Hiraishi and Butt teaches “delay[ing] the first read strobe by a first predetermined amount to generate a first delayed read strobe,” “wherein the first predetermined amount is determined based at least on signals received by the first data buffer during one or more previous operations,” as well as the “sample” and “transmit” operations recited in claim 1. We also find, as discussed above, that a person of ordinary skill in the art would have combined the teachings of Hiraishi and Butt and would have had a reasonable expectation of success in arriving at the claimed invention. c) Conclusion for Claim 1 We conclude that the subject matter of claim 1 would have been obvious based on the combined teachings of Hiraishi and Butt.” slip op. at 19
