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.

“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.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“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. 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

- Prior constructionPrior construction adoptedDecided for patent owner
“We have reviewed the court’s claim-construction order, and adopt its construction of the following terms for purposes of this Decision. First, we construe “node,” which is recited in multiple claims, as “an identifier of a resource that includes an address to the resource and the duration for which the resource’s content is to be presented by default.” See Ex. 1123, 16–17; Prelim. Resp. 10–12. Second, we construe “show structure of nodes,” which is recited in each of challenged independent claims 22 and 46, as well as dependent claim 45, as “a structure that is arranged for the display of content by specifying one or more paths through a plurality of nodes. The show structure of nodes specifies the duration of any display,” but there is no durational requirement separate from the construction of “node.” See Ex. 1123, 2–13; Ex. 2107, 5; Prelim. Resp. 9. For purposes of this Decision, we accord all other terms recited in the challenged claims their plain and ordinary meaning. See Ex. 1123, 17–20, 26–29 (court adopting plain and ordinary meaning of “plurality of accessible resources,” “content,” “without requiring user input,” “in accordance with said show structure,” “providing,” and “search results”); see Prelim.
