Resp. 6 (“Patent Owner does not necessarily agree with all aspects of Petitioner’s proposed level of ordinary skill, but does not believe that resolving that level is necessary to resolve the issues raised in this preliminary response.”) The portion of the definition proposed by the Petitioner requiring “a bachelor’s degree in computer science, computer engineering, or a comparable field and at least two years of professional experience working with graphical user interfaces and applications for computers” appears to be consistent with the problems and solutions in the ’758 patent and prior art of record and is supported by declarant testimony. We adopt this as the definition of one of ordinary skill in the art for the purposes of this Decision. We note that since it is unclear whether the bachelor’s degree in the proposed definition is considered by Petitioner to be “an advanced-level degree” we do not adopt the portion of the definition relating to the substitution of years of experience for a degree at this time.

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

    “We determine that, on this record and for the purposes of institution, Petitioner has made a sufficient showing regarding motivation for its proposed combination of Chaudhri, Martyn, and Griffin. For the combination of Chaudhri and Martyn, we determine, on the present record and for the purposes of institution, that Petitioner has sufficiently shown support for the use of Martyn’s snap-shot menu with Chaudhri’s user interface. We acknowledge Patent Owner’s declarant’s examples of instances in which devices that incorporated “popular user interface features . . . did not achieve the same level of success because of poorly articulated design implementation.” Ex. 2001 ¶ 127 (cited at PO Resp. 23). However, on the present record, this evidence does not specifically address whether one of ordinary skill would have found such examples significant enough or relevant enough to the proposed combination to dissuade one of ordinary skill from considering such a combination to be reasonably likely to succeed, especially in light of the testimonial evidence before us that similar menus were often incorporated into GUIs similar to Chaudhri’s, which is adequately supported by reference to numerous examples. See Ex. 1003 ¶¶ 43–48, 64–65 (cited at Pet. 16). Additionally, we find compelling that Chaudhri describes a pop-up dialogue sub-menu for a different purpose (modifying the user interface object). See Ex. 1004 ¶¶ 274, 317, Figure 5LLL; Pet. 18–19; Ex. 1003 ¶ 69. On the present record, one of ordinary skill in the art would have found the use of the similar snap-shot menu from Martyn (offering different functionality) to be further prompted by this sub-menu, and not to have been redundant or “already solved” in Chaudhri, as Patent Owner argues (PO Resp. 26–27). See Pet. 18–19; Ex. 1003 ¶ 69. introduced to the combination of Chaudhri and Martyn to address a conflict that arises because Petitioner proposes a combination of Chaudhri and Martyn that “create[s] a conflict of assigning two functions to the same gesture.” PO Resp. 20. However, Petitioner provides a number of rationales to combine, and Petitioner’s argument that one of ordinary skill would have sought details from Griffin to implement Chaudhri’s teachings describing different user functionality being launched by user touches of different user durations (Pet. 19–21) adequately supports the use of the material from Griffin in the proposed combination. See Ex. 1004 ¶¶ 217, 218; Ex. 1002 ¶¶ 70–73, 75; see also PO Resp. 24 (describing “multiple types of gestures” used Chaudhri). While the proposed combination of Chaudhri and Martyn would, as Petitioner asserts, result in “three distinct operations invoked by duration-based touch gestures at an application icon” (Pet. 21), two of these distinct operations are found in Chaudhri’s teachings, and thus, on the present record, the motivation to look to Griffin does not arise only from the proposed combination of Chaudhri with Martyn. On the present record and for the purposes of institution, we determine that Petitioner has adequately shown that one of ordinary skill would have looked to Griffin to supply additional information regarding implementation of Chaudhri’s (and the Chaudhri and Martyn combination’s) use of parameters of a user’s touch, including duration, to enable different functionalities. Ex. 1006 ¶¶ 40, 53, Fig. 7; Ex. 1002 ¶¶ 70–73, 75. With respect to the use of the “press-and-hold” feature from Martyn, rather than other possibilities from Martyn for triggering its snap-shot menu and rather than adding a second touch point as Patent Owner suggests (PO Resp. 27–28, 32, 33 (citing Ex. 2001 ¶¶ 142–143, 156, 166, 172–173)), on to have been a suitable option.

Cir. 2021) (determining that a showing of the obviousness in “predictable use of prior art elements according to their established functions” (as per KSR, 550 U.S. at 417) requires only a showing that the combination be a suitable option, rather than a showing that it is the best option).” slip op. at 20

    “We agree with Patent Owner that the desired signal and interferer signal must be received at the same time. The plain language of the claim requires the wireless transceiver to “receiv[e] a wireless signal having a desired signal and an interferer signal,” the determining of a signal strength of the interferer signal and the determining of a signal strength of the desired signal must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. The specification supports this understanding. “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:20–22; see also id. at 5:31–33 (“FIGS. 2A and 2B illustrate examples of desired signals, interferers, and noise that may be received by one of the various circuits in a” slip op. at 21

    “We agree with Patent Owner that Rauhala does not state that the signal strengths are measured simultaneously or at the same time. Indeed, as discussed above, Rauhala indicates unequivocally in the same paragraph the opposite—that detector DET provides to control unit 42 “an indication about either the receive channel signal strength RSS or the strength of any signal on the reception band.” Ex. 1004 ¶ 17. Rauhala describes that “control unit 42 provides two one-bit control signals cA and cM” based on indications received from detector DET. Id. Importantly, Rauhala indicates that “at the same time as” describes how the control unit 42 uses the received inputs RSS and RSSn shown in Figure 4, which are described earlier in paragraph 17 as indications of either RSS or RSSn from detector DET. Id. (“Signal cA is 0 when signal RSS is greater than S4 and signal RSSn is at the 11 Dr. Baker’s reply declaration correctly quotes Rauhala paragraph 17 but cites to paragraph 18. We deem this harmless error. same time smaller than Sn. . . . Signal cM is 1 when signal RSS is not greater than S4 and signal RSSn is at the same time at least Sn. Otherwise, signal cM is 0.”). The burden remains on Petitioner to demonstrate by a preponderance of the evidence that Rauhala discloses the disputed limitations as arranged or combined in the claim. Petitioner does not persuasively reconcile these “either/or” statements regarding the functioning of detector DET with the “at the same time as” statements regarding control signals output by control unit 42 in paragraph 17. We do not find persuasive Petitioner counsel’s position expressed at the hearing that Rauhala’s “either/or” statements are “simply an imprecise description” (Tr. 16:22–24). We do not see a lack of precision in Rauhala’s “either/or” statements.” slip op. at 30

    “When asked at his deposition to explain Rauhala’s use of the word “or” regarding the functioning of detector DET, Dr. Baker asserted that “[detectors] can be designed to determine RSS or RSSn.” Ex. 2016, 85:5– 12. We find Dr. Baker’s testimony that “it’s reasonable that if you can design . . . the detector to detect one or the other, you can also design it to detect both” to be without factual support. Id. at 85:13–16. He points to no textbook or other independent evidence to support that would have led one of ordinary skill to design such a detector or to support that one of ordinary skill would have understood Rauhala’s detector to be so designed. Furthermore, Dr. Baker recognizes that “Rauhala doesn’t teach the details of what’s in the detector.” Id. at 91:6–7. We give little weight to Dr. Baker’s unsupported testimony that one could design a detector to detect both RSS and RSSn from the same wireless signal.

Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process.

On this preliminary record, Petitioner’s interpretation of “available capacity” as including “a single radio, a group of radios or the entire DAS system, [able to] be determined using throughput, number of connections, number of users, number of carriers, or power,” is sufficient for purposes of institution. See Pet. Reply 3 (citing Ex. 1005, 4:24–27; 5:13–15; 6:1–4; Ex. 1003 ¶¶ 104–06). On this preliminary record, as Petitioner argues (Pet. Reply 2) and contrary to Patent Owner’s construction, the claim language and the specification do not support limiting available capacity to a single RRU, or similarly, limiting the scope of “load percentage” to a load consumed by a remote radio unit divided by the assigned available capacity for that remote radio unit.6” slip op. at 13

    “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.

    “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.

    “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

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.

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.

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; 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.

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.
