“the Board’s preliminary construction only adds ambiguity to the meaning of this term because it requires “a number of vertical contacts that . . . provide contacts on the surface of the memory die,” and further, claim 1 already recites that “‘a second integrated circuit functional element’ has ‘a number of contact points distributed throughout the surfaces of said functional element.’” See id. at 9 (emphasis added). Therefore, Patent Owner offers the following “suggest[ion]”: “To the extent that the Board finds it necessary to mention contacts in the context of the claimed ‘memory array,’ Patent Owner suggests that the Board use the term ‘a number of vertical contacts distributed throughout the surface of and traversing the memory die.’” PO Resp. 8 (emphasis added). For reasons discussed further below and in the Institution Decision, the record, including the specification, supports Patent Owner’s suggestion, and we determine that Patent Owner’s claim construction suggestion is materially the same as the preliminary claim construction set forth in the Institution Decision. See, e.g., Ex. 1001, 2:41–44 (“[S]ince these differing die do not require wire bonding to interconnect, it is now also possible to place interconnect pads throughout the total area of the various die rather than just around their periphery.”) (emphasis added); Inst. Dec. 24–25. In addition to Patent Owner’s suggestion above, Patent Owner also argues that “the term ‘a memory array functional to accelerate external memory references to the processing element’ means ‘a memory array that allows the parallel loading of data through buffer cells.’” PO Resp. 6 (emphasis added). Patent Owner asserts that “[i]n its preliminary response, Patent Owner advocated that this term should be accorded its plain and ordinary meaning.” PO Resp. 5. It is not clear if Patent Owner maintains (i.e., in its Response) that the phrase carries its plain and ordinary meaning.9 In any event, the record does not support Patent Owner’s proposed requirement for “buffer cells” under the plain and ordinary meaning of the “functional to accelerate” clause or under lexicography principles, prosecution history or otherwise, for the reasons advanced by Petitioner and as addressed below. In line with Patent Owner’s suggestion and as we similarly determined in the Institution Decision, the “functional to accelerate” limitations require “a number of vertical contacts distributed throughout the surface of and traversing the memory die in a vertical direction (vias) to allow multiple short paths for data transfer between the memory and processor.” See Ex. 1001, Fig. 4 (showing numerous contact points); Inst.

“As Petitioner argues, the combined Koyanagi and Alexander system mimics the ’951 patent’s disclosure by employing stacked dies with a “large number of contact points distributed throughout the surfaces of the dies.” Pet. 29; see also supra notes 14, 16. Petitioner also provides evidence that an artisan of ordinary skill would have known of several advantages in stacking 3D chips with multiple vias including “high packing density,” “high speed,” “parallel signal processing,” and “integration of many functions on a single chip.” Id. at 4 (citing Ex. 1010, 1704; Ex. 1002 ¶ 39). Petitioner points to Koyanagi’s “key benefit” as “enab[ling]large data bandwidth in vertical data transfers” (Ex. 1007, 17) to mitigate bus bottlenecks, further showing that multiple vias provide for parallel signal processing and increased processing speed in stacked dies as found above. See Pet. 30 (citing Ex. 1007, 17, 19); supra § II.C (Claim Construction); supra notes 14, 16. In other words, Petitioner shows how the combined teachings of Koyanagi and Alexander teach or suggest to an artisan of ordinary skill the accelerate clause in the challenged claims by providing a large number of short parallel via connections, thereby functionally enabling large data bandwidths and parallel processing, as was well-known at the time of the invention. See Pet. 4, 17–23, 28–29; Ex. 1007, 17–18; supra notes 14, 16; Reply 15–17; In re Graves, 69, F.3d 1147, 1152 (Fed.

“As Petitioner also argues and as summarized above, the Petition “provide[s] a detailed explanation of how Koyanagi and Alexander would have been combined to disclose each limitation of the Challenged Claims and why a POSITA would have been motivated to combine them––‘to create a 3D reconfigurable processor module with improved performance and areaefficiency.’” Reply 16 (quoting Pet. 17). By way of example, Petitioner’s annotated Figure 1M, which represents combined teachings of Koyanagi and Alexander, shows how to connect the dies together using conductive vias as challenged claim 1 requires. Petitioner also provides persuasive detail with respect to the remaining challenged claims at issue in this section (i.e., claims 4, 5, 8, 10, 13–15). See Pet. 31–46. By teaching similar stacking techniques for similar circuits including the use of conductive vias with logic dies including FPGAs, memory, and microprocessors, Koyanagi and Alexander collectively evidence a reasonable expectation of success without undue experimentation in arriving at the claimed invention. See Otsuka Pharm. Co., v. Sandoz, Inc., 678 F.3d 1280, 1296 (Fed. Cir. 2012) (“The inventor's own path itself never leads to a conclusion of obviousness; that is hindsight. What matters is the path that the person of ordinary skill in the art would have followed, as evidenced by the pertinent prior art.”). In other words, Petitioner shows that the claimed invention involves a routine combination of familiar elements to yield predictable results, namely combining Alexander’s known 2D-FPGA die with Koyanagi’s similar die stack, or simply substituting Alexander’s known 2D-FPGA die in place of a similar DRAM memory die in the die stack of Koyanagi, with the coupled circuits functioning with processing speed gains and other benefits as expected. See Pet. 27–29; Reply 14 (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.”)).” slip op. at 42

“These claim construction arguments that rely on “buffer cells” fail for the reasons noted above, the challenged claims do not require buffer cells. See supra § II.C (Claim Construction). As summarized above, the ’951 patent describes in its abstract and other places, including in reference to Figure 4, providing accelerated data transfers and reconfiguration without buffer cells by using numerous short vias to connect circuits in the stacked dies. See id. As outlined above, Petitioner provides ample motivation supported by the record as to “how and why” an artisan of ordinary skill would have combined the stacked die features of Koyanagi with the similar features of Alexander, to include the well-known FGPA, and it shows how the vertical interconnections employed in both references track the disclosed invention to obtain the claimed acceleration. See, e.g., Pet. 29 (annotating Koyanagi’s Figure 1). Wiring similar well-known circuits with short conductive vias instead of long conventional conductors would have been obvious and well-within the ordinary skill of an artisan, motivated by many reasons (for example, speed/bandwidth gains, compactness, power consumption, FPGA design flexibility) as the Petition shows and as Koyanagi and Alexander suggest as discussed above. See, e.g., Ex. 1006, Abstract (describing a “fabrication technology” and “expected manufacturing yield”), 1 (describing “10,000 solder bumps” “to establish the vertical interconnections” and “enabling electrical interconnections between the two sides of the die,” by “adapting multi-chip module (MCM) fabrication technology”); Ex. 1007, 17 (similarly describing MCM technology and using 10,000 (105) “interconnections per chip” to make 3D MCMs “fabricated using our new integration technology”), Fig. 6 (showing “Fabrication sequence of 3D LSI”).” slip op. at 37

“However, as Petitioner argues and as Dr. Chakrabarty confirms, using many short vertical conductive vias (e.g., TSVs) versus long conductive runs “reduces power consumption and improves heat removal (because TSVs also serve as heat pipes).” Reply 17 (citing Ex. 1007, 17). In other words, Dr. Chakrabarty acknowledges that [w]hat Koyanagi says is actually obvious to anybody who is skilled in the art. Anybody who is skilled in the art would know that via is conductive. It is a conductor for both electricity and for heat. And therefore, if you have lots of vias, you’re going to take out the heat. Ex. 1035, 256:9–15 (emphasis added); see Reply 17 (partially quoting Ex. 1035, 256:9–15). Therefore, as Petitioner persuasively argues, rather than ignoring thermal issues or deterring a person of skill in the art from combining Koyanagi and Alexander, “a POSITA would have been motivated to find a solution to the alleged thermal issues, and would have recognized that a large number of 3D interconnections between dies contribute to such a solution.” See Reply 21 (citing Ex. 1030 ¶ 53).” slip op. at 50

“Patent Owner, in focusing on this portion of the ’226 patent disclosure, does not adequately explain why buffer cells and configuration memory cells must be included in the proper construction of “wide configuration data port,” and seeks to import a functional description of the use of a wide configuration data port (“that allows parallel updating of logic cells in a programmable array through use of buffer cells”) into the claim construction. PO Resp. 11–14; PO Sur-reply 2–4. While the discussion in the ’226 patent describes an example of a wide configuration data port used in a specific way that aligns with Patent Owner’s proposal (Ex. 1001, 4:45– 59), other examples of the use of a wide configuration data port are included (id. at 4:59–65), and therefore we do not agree that one of ordinary skill would understand this use to be part of the construction of the term. We agree with Petitioner that the proper construction of the term does not require buffer cells to be specifically described. See Pet. Reply 6–9. Rather, we note that the specification of the ’226 patent contrasts loading of data to an FPGA in a byte serial fashion through a narrow port, which “results in [] long reconfiguration times,” with the use of a wide configuration data port, and therefore we determine that one of ordinary skill would understand the wide configuration data port, in contrast to the byte serial “relatively narrow” port, to include parallel connections between cells in the dies. See Ex. 1001, 4:3–9. This additionally is consistent with certain arguments by Patent Owner, for example in the Patent Owner’s Response, which opens with a discussion of the “inventive” processor’s arrangement of die-area contacts, such as through-silicon vias, “into a wide configuration data port” and we find that description more consistent with the proper construction of this term.

Inc. v. Home Depot U.S.A., Inc., 412 F.3d 1291, 1298 (Fed. Cir. 2005). Conversely, structural features that do not actually perform the recited function do not constitute corresponding structure and thus do not serve as claim limitations. Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308–09, (Fed. Cir. 1998); see B. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed. Cir. 1997) (“[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.”). Given our construction of wide configuration data port, Patent Owner’s argument that the corresponding structure for this limitation must require that buffer cells on one die element are connected in parallel to cells on another die element is based on the description of the use of buffer cells as used in the updating of the FPGA while it is in operation. PO Supp. Br. 3 (citing Ex. 1001, 4:50–54, Fig. 5). However, we note that this description is followed by the disclosure that “[t]he buffer cells 88 are preferably a portion of the memory die 66.” Ex. 1001, 4:50–54. It does not appear, therefore, that buffer cells are always a portion of the memory die, or are required when the FPGA is not in operation, and thus we decline to require in the corresponding structure that they be specified to be on a specific separate die element. Rather, we find that what is disclosed as actually performing the recited function of “reconfiguring the programmable array within one clock cycle” is “a wide configuration data port and contact points formed throughout the area of the first integrated circuit die element and another integrated circuit die element.” The support for this is found in the ’266 patent’s comparison of the long reconfiguration times through a narrow port (Ex. 1001, 4:3–9) with the time to reconfigure through a wide configuration data port with a significantly increased number of connections (id. at 4:45– 65), and the implementation of this in a module that has multiple dies “which have a number of corresponding contact points, or holes, 70 formed throughout the area of the [die] package” (id. at 4:9–20).

This lack of antecedent basis renders proposed substitute claim 24 indefinite, as we noted in our Preliminary Guidance. Pet. Opp. to RMTA 25; Prelim. Guidance 8 (“Proposed substitute claim 24 also recites ‘the handheld device’ and also suffers from the lack of antecedent basis). Despite having the opportunity to correct its error and amend proposed substitute dependent claim 24 when independent claim 14 was amended to remove the recitation of “a handheld device,” Patent Owner did not do so in its Contingent Revised Motion to Amend. RMTA 31. Proposed substitute claim 24 is indefinite because the claim “fails to inform, with reasonable certainty, those skilled in the art about the scope of the invention.” Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 901 (2014); see USPTO Memorandum on the Approach to Indefiniteness Under 35 U.S.C. § 112 in AIA Post-Grant Proceedings (Jan. 6, 2021)13; see MPEP 2173.05(e) (9th ed., Rev. 08.2017, June 2020). This is because “the handheld device” is only recited in proposed substitute claim 24, and the proposed substitute claim fails to inform one skilled in the art the scope of invention related to synchronizing “data on the handheld device” “in the virtual smart phone.” Because proposed substitute claims 25 and 26 depend from proposed substitute claim 24, we similarly agree with Petitioner that claims 25 and 26 also are indefinite for lacking an antecedent basis for the term “handheld device.” Pet.

“Whether to treat a preamble term as a claim limitation is determined on the facts of each case in light of the claim as a whole and the invention described in the patent.” Am. Med. Sys., Inc. v. Biolitec, Inc., 618 F.3d 1354, 1358 (Fed. Cir. 2010) (quoting Storage Tech. Corp. v. Cisco Sys., Inc., 329 F.3d 823, 831 (Fed. Cir. 2003) (internal quotation marks omitted). “Absent clear reliance on the preamble in the prosecution history, or in situations where it is necessary to provide antecedent basis for the body of the claim, the preamble generally is not limiting.” Symantec Corp. v. Computer Assoc. Int’l, Inc., 522 F.3d 1279, 1288 (Fed. Cir. 2008) (internal quotation marks omitted). When the limitations in the body of the claim rely upon or derive essential structure from the preamble, then the preamble acts as a necessary component of the claimed invention and is limiting. See Eaton Corp. v. Rockwell Int’l Corp., 323 F.3d 1332, 1339 (Fed. Cir. 2003). A claim preamble also is limiting if the preamble is “necessary to give life, meaning, and vitality” to the claim. Pitney Bowes, Inc., 182 F.3d at 1305. We disagree with Patent Owner. Specifically, we do not agree that limitations in the body of the claims require the preamble to serve as an antecedent basis nor do they derive essential structure from the preamble. Rather, all of the elements recited in the body of claim 1 comprise a “virtual smart phone.” That is, we do not discern, and Patent Owner fails to persuasively point us to, any structure imparted by the preamble’s recitation of a “virtual smart phone.” See Pet. Reply 1–2. We similarly do not agree that the without the term “virtual smart phone” there would be no understanding of the “emulating” or “handheld device” limitations. Rather, the recited “software application executing on the processor” limitation provides the structure and meaning for the “emulating” of the “handheld device” features. Furthermore, we agree with the Petitioner that there is no evidence in the record that the prosecution history requires that the preamble is limiting, and the claims were distinguished during prosecution based on the recitation of a “virtual” smart phone. Id. at 2–3. Accordingly, we do not agree with Patent Owner that the preamble is limiting. slip op. at 7

“on the process to . . . emulate features of a handheld device.” Ex. 1001, 12:58–60 (emphasis added). Patent Owner argues that the term “‘emulate’ has a meaning in the art that is common and understood to mean ‘to imitate.’” PO Resp. 18. Patent Owner provides a dictionary definition to support its contention. Ex. 2004 (defining “emulate” as “to imitate in an effort to equal or surpass”). Patent Owner contends the use of “emulate” in claim 1 comports with its commonly understood meaning as “to imitate,” as does the use of the term “emulate” in the written description. Pet. 18–20 (citing Ex. 1001, 1:66–2:3, 2:6–3:5, 12:54–13:2 (claim 1)). Petitioner argues that the term “emulate” should be given its plain and ordinary meaning and does not contest Patent Owner’s construction of the term “emulate” as “to imitate.” Pet. 6–7; Pet. Reply 7. Petitioner, however, contests Patent Owner’s application of that construction to the asserted prior art. Pet. Reply 4–7 (citing Ex. 1034 ¶¶ 24–26). Petitioner specifically argues that Patent Owner implies that “(1) the imitation must be an exact duplicate in display and manner of input . . . or (2) the imitation relates only to the display and touch screen aspects.” Pet. Reply 4–5. In support of its position that Patent Owner’s interpretation of “to imitate” improperly narrows the meaning of “emulate,” Petitioner contends the written description discloses “less than full replication as emulation” and “controlling the handheld device th[r]ough control of a projected image using a variety of control input mechanisms provides emulation.” Pet. Reply 5–6 (citing Ex. 1001, 2:2–5, 3:57–61, 4:63–66, 6:24–42). Petitioner also notes that the dictionary definition Patent Owner proffered indicates that an exact duplication is not required. Pet. Reply 7 (“The complete definition of emulate [as] ‘to imitate in an effort to equal or surpass.’ Ex. 1004, 3”). We conclude that a preponderance of evidence supports the construction of the term “emulate” to mean “to imitate,” without any further restriction such as exact duplication or only display or touch screen aspects. Accordingly, we construe the term “emulate” as “to imitate.”” slip op. at 9

“limiting. See Pet. Reply 5; PO Sur-reply 7–8; Tr. 8:5–15. “In general, a preamble limits the invention if it recites essential structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quoting Pitney Bowes, 182 F.3d at 1305). On the other hand, a preamble generally is not limiting “where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.” Id. (quoting Rowe v. Dror, 112 F.3d 473, 478 (Fed. Cir. 1997)). For example, if “deletion of the preamble phrase does not affect the structure or steps of the claimed invention,” the preamble is not limiting. Id. at 809 (citing IMS Tech., Inc. v. Haas Automation, Inc., 206 F.3d 1422, 1434 (Fed. Cir. 2000)). Here, we are persuaded the preamble is limiting. Although the parties dispute whether spatial multiplexing and transmit diversity occur simultaneously, it is undisputed that spatial multiplexing is part of the claimed invention. See Pet. 2; PO Resp. 6; Tr. 6:13–26 (Petitioner indicating “we agree that the claims require transmit diversity and signal multiplexing”). The Specification supports this view. For example, the Specification states that “i[t] is an object of the present invention to improve reception performance of specific data on a receiving side while maintaining the transmission efficiency of a communication system.” Ex. 1001, 2:3–6 (emphasis added). The technique for improving transmission efficiency disclosed in the Specification is spatial multiplexing. See id. at 5:13–17 (describing “two transmission systems to transmit different items of data, [which] maintains high transmission efficiency”), Figs. 3, 4; see also id. at 1:42–47 (indicating “signals sent from a plurality of transmission antennas at the same timing and same frequency in substream units” help “realize a high-speed, high-volume communication”). Further, the only part of claim 1 that recites spatial multiplexing is the preamble. See Pet. Reply 3–6; PO Sur-reply 4; Ex. 1020, 21:22–22:18. Neither party indicates that any other claim language captures spatial multiplexing. Thus, if the preamble is not limiting, claim 1 would not incorporate spatial multiplexing at all, which is inconsistent with how the invention is described in the Specification. Consequently, we determine that the preamble of claim 1 recites “essential structure or steps” and, thus, is “necessary to give life, meaning, and vitality” to the claim. See Catalina Mktg., 289 F.3d at 808.” slip op. at 10

“The final limitation of claim 1 (the “wherein” clause) recites “generat[ing] a replica data item by replicating a specific data item of the plurality of data items, and map[ping] the plurality of data items to the at least one of the plurality of antennas such that the specific data item and the replica data item are transmitted from different antennas at a same time.” It is undisputed that this limitation recites transmit diversity. Critically, as Patent Owner observes, this limitation recites “a specific data item of the plurality of data items” (emphasis added), i.e., the “specific data item” that is replicated for transmit diversity is part of the same “plurality of data items” recited in the preamble for spatial multiplexing. See PO Resp. 7 (“Therefore, the specific data item described in transmit diversity (TD) with the replica data item, is also involved in spatial multiplexing (SM) at the same time . . . with other data items of the plurality [of] data items . . . .”); PO Sur-reply 4 (asserting that the “same ‘plurality of data items’ are subject to spatial multiplexing in the preamble and transmit diversity in [the ‘wherein’ clause]”); Tr. 44:22–45:2. Consequently, in order for both the preamble limitations and the “wherein” clause limitations to be met, a plurality of data items, including the specific data item, must be transmitted via spatial multiplexing, i.e., using a plurality of antennas in parallel. In other words, both the specific data item and at least one other data item that is different (i.e., the recited “plurality”) must be transmitted at the same time. In addition, both the specific data item and its replica data item must also be transmitted at the same time, as recited in the “wherein” clause, for transmit diversity. Thus, at least three data items—the specific data item, its replica, and another different data item—must be transmitted at the same time to satisfy the claim because both spatial multiplexing (preamble) and transmit diversity (“wherein” clause) must occur. See PO Resp. 7; Pet. Reply 2–3; Ex. 1020, 12:17–21. As a result, the claim requires simultaneity.” slip op. at 13

“Although we agree with Patent Owner that the broadest reasonable interpretation does not simply mean the broadest interpretation (PO Resp. 13), we are not persuaded by Patent Owner’s contention that the broadest reasonable claim construction for “first information sequence” should be “important information.” Id. at 15. As Petitioner points out during oral arguments, the claims are not specific as to what “first information” is other than “first” is merely used to “differentiate” it from “second” information, “a very common thing when it comes to patent claim drafting.” Tr. 18. As Petitioner points out, “the Federal Circuit said the use of terms first and second is a common patent law convention to distinguish between repeated 12 instances of an element or limitation, which is exactly how Patent Owner has used it here.” Id. (citing 3M Innovative, 350 F.3d at 1371). Further, as Petitioner points out, dependent claims 5–6 and 13–14 limit the “first information sequence” from the respective independent claims to “specific types of information,” including “retransmission information” and information “used for an error control.” Pet. Reply 1–2. That is, “where the applicant intended to limit an information sequence to a specific type, it made those narrowing characteristics express.” Id. at 2 (citing Phillips v. AWH Corp., 415 F.3d 1303, 1314 (Fed. Cir. 2005) (en banc) (“Other claims . . . can also be valuable sources of enlightenment as to the meaning of a claim term.”)). As Petitioner points out, here, Applicant chose not to limit (at least in the independent claims) the sequences of bits “to any particular type.” Id. Accordingly, we are unpersuaded by Patent Owner’s contention that the Specification shows that (1) “features of the present invention as a whole” limit the scope of the claims and (2) the Specification’s repeated descriptions mapping “important information” to “the first and second bits.” PO Sur-reply 5. Given the broadest reasonable interpretation in view of the Specification, we construe the term “first” information sequence as a particular information sequence, and “second” information sequence as another information sequence distinguishable from the “first.” The Specification, including the claim language and the prosecution history, do not compel any different conclusion. We also are persuaded by Petitioner’s contention that adding a subjective term such as “important” into the claim construction would 13 introduce ambiguity. Tr. 20–21. Thus, we agree that we should not adopt a construction that replaces an unambiguous claim limitation with one that depends on purely subjective opinion. See Intellectual Ventures, 902 F.3d at 1381. Thus, we conclude “first information sequence” can be any information sequence that if different from a “second information sequence,” wherein “a sequence of bits” are generated including “at least one bit” of each of the first and second information sequences.

Even Patent Owner concedes that Claim 12 of Nakamura discloses that “necessary signals could include ‘one or more’ of pilot signals, synchronization information, order number, and TPC information.” Sur-Reply 4 (citing 1004, 15:51–61). The Supreme Court has stated that the “combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416; Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1161 (Fed. Cir. 2007) (quoting KSR, 550 U.S. at 416). According to Petitioner, “[t]he proposed modification to Nakamura would be straightforward, not requiring undue experimentation, and would produce predictable results.” Pet. 25. That is, “it would have been natural and an application of nothing more than ordinary skill and common sense.” Id. at 25–26. Here, the question is whether combining Okumura’s teaching of using both pilot and TPC symbols in the same necessary signal with Nakumura’s necessary signals comprising control data, such as pilot symbols and TPC symbols, was “uniquely challenging or difficult for one of ordinary skill in the art” or “represented an unobvious step over the prior art.” Leapfrog Enters, 485 F.3d at 1162 (citing KSR, 550 U.S. at 421). As Petitioner points out, Patent Owner’s Expert, “Dr. Vojcic admitted that no technical barriers would have prevented a POSITA from modifying the expressly disclosed embodiments of Nakamura to combine pilot and TPC symbols.” Reply 11 (citing Ex. 1016, 34:14–35:20). We view Petitioner’s combination as being akin to a simple substitution of Okumura’s use of both pilot and TPC 34 symbols in Nakamura’s necessary signals. Cf. KSR, 550 U.S. at 417 (indicating determining obviousness is easier when the claimed subject matter involves “a simple substitution for one known element for another or the mere application of a known technique to a piece of prior art ready for improvement.”). We are unpersuaded by Patent Owner’s contention that “[t]he Petition’s proposed combination of Nakamura and Okumura is guided by the ’563 patent and driven by hindsight.” PO Resp. 32. Rather, we agree with Petitioner that Nakamura and Okumura provide sufficient motivation for combining the references in the manner required by the claims. Pet. 24–25 (citing Ex. 1004, 15:53–61; Ex. 1005, 14, 18, Fig. 2; Ex. 1003 ¶¶ 53–54). First, although Patent Owner contends that “there is no discussion of the benefits gained by sending both pilot and power control symbols” (PO Resp. 32 (citing Pet. 21), we agree with Petitioner that Nakamura explains that pilot symbols permit ‘coherent detection with interpolation at a receiving side’ and that power control symbols permit ‘carrying out a transmission power control’” and this provides a reason one of ordinary skill in the art would make Petitioner’s proposed combination. Ex. 1004, 11:48–50 (“In this eighth embodiment, the necessary signal generation unit 10 includes pilot signals to be used in carrying out the coherent detection with interpolation at a receiving side”), 13:11–14 (“In this eleventh embodiment, the necessary signal generation unit 10 includes a transmission power control information which is necessary in carrying out a transmission power control.”); Pet. 21 (quoting Ex. 1004, 11:48–50, 13:11–14)). Thus, although Patent Owner contends that Nakamura “does not” slip op. at 34
