      “d. Conclusion Regarding Asserted Obviousness over Kim In sum, for the reasons discussed above, Petitioner’s showing regarding claim 1 is sufficient for institution. Accordingly, having reviewed the Petition, Preliminary Response, and evidence cited therein, we determine that Petitioner has established a reasonable likelihood that Kim renders obvious claim 1. As such, Petitioner’s showing is sufficient to institute an inter partes review on all challenged claims on all asserted grounds. 37 C.F.R. § 42.108(a) (“When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.”); see SAS Inst. v. Iancu, 138 S. Ct. 1348, 1359–60 (2018). Notwithstanding, we address other claims and other grounds below, particularly in response to Patent Owner’s preliminary arguments.” slip op. at 29

      “standards for finding lexicography in a specification are exacting. Hill-Rom Services, Inc. v. Stryker Corp., 755 F.3d 1367, 1371 (Fed. Cir. 2014). “To act as its own lexicographer, a patentee must clearly set forth a definition of the disputed claim term other than its plain and ordinary meaning and must clearly express an intent to redefine the term.” Id. (internal quotations omitted). As Patent Owner correctly notes, the specification states: In various embodiments, the contact pressure level may be represented by a touch state. In the context of the present description, a touch state refers to a predefined subset of the range of measurable contact pressures. For example, in one embodiment, contact pressure levels may be represented as one of four predefined touch states: no touch, light touch, medium touch, and heavy touch. Ex. 1001, 19:35–41; Prelim. Resp. 27 (quoting Ex. 1001, 19:35–41). Patent Owner, however, has not identified any words of manifest exclusion or restriction in that passage that indicate an intent to redefine the claim term. Rather than indicating the claims are to be restricted, the specification indicates how that the term “touch state” is to be understood in the descriptions presented in the specification.

      “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. See 37 C.F.R. 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Xerox Corp. v.

      “The two proposals are materially similar in the education requirement, but differ marginally in professional experience required (three versus five years). See supra. While we were persuaded, on the preliminary record, that both Petitioner’s and Patent Owner’s proposals were consistent with the problems and solutions in the ’202 patent and the prior art of record, on balance, we determined that Petitioner’s proposal was a better reflection of the level of skill in the prior art, and we therefore adopted it for our Institution Decision. See Institution Dec. 12–13. For this Decision, we adopt the description of the person of ordinary skill articulated by Petitioner and used previously in our Institution Decision. In light of our review of the complete record, we find that this formulation is consistent with the ’202 patent, the prior art of record, and is supported by the testimony of Dr. Baker.

      “requirement.” Pet. Reply 5. We do not agree with Petitioner. We find that the language of the claims supports Patent Owner’s argument that the desired signal and the interferer signal are received together. As discussed infra, claim limitations 7.7 and 7.8 recite determining a signal strength of the interferer signal and determining a signal strength of the desired signal. These determinations must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. See Larson II Decl. ¶ 70; Baker II Decl. ¶¶ 48–49 (explaining that consideration of signal strengths detected at the same time would be “essential”). The specification of the ’202 patent further supports this finding: “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, 5:22–24; see also Figs. 2A, 2B (showing interferer signals and desired signals together).” slip op. at 17

      “Pet. 5–6 (citing Ex. 1003 ¶ 50). Petitioner further states “that more education could compensate for less experience and vice versa.” Id. at 6. Petitioner’s position is, therefore, consistent with Patent Owner’s proffered level of skill in the art which reflects less education and more experience in substantially the same fields. Specifically, Patent Owner asserts that such a skilled artisan “would have at least a bachelor’s degree in mechanical or automotive engineering and/or five or more years of experience in the automotive industry designing, developing, testing, and engineering automotive components or practical experience servicing, assembling, repairing, and/or developing internal combustion engines and/or engine oil filters.” Prelim. Resp. 4. On this record, we determine that the level of ordinary skill is reflected in the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (specific findings on the ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163–64 (Fed. Cir. 1985))). A more specific definition is not necessary for purposes of deciding whether to institute review.

Specifically, § 609.04(a)(III) states that “[e]ach information disclosure statement must further include a concise explanation of the relevance . . . of the information listed that is not in the English language.” (italicized emphasis added, underlining in original); see also § 609.01 B.3 (stating this requirement). It does not appear that any concise explanation was filed with respect to either Japanese reference filed in the IDS.

Compare Ex. 1007 (containing Japanese text with Figures 1–7c), with Ex. 1008 (containing English text along with Figures 1–7c). As such, the Yokoyama reference relied on in the Petition––being in English––contains roughly ten pages of more readily discernible information than the Japanese-language version of this reference submitted during prosecution. Significantly, Petitioner relies on textual disclosure in the English-translated version of Yokoyama in its challenges. Pet. 28–51, 54, 58, 59 (citing Ex. 1008 repeatedly). Such English-translated disclosure was not previously before the Examiner. Ex. 1002, 13–38. In view of this additional disclosure before us in English, i.e., disclosure that was not presented previously to the Office, we find that the English translated version of Yokoyama relied on here (Ex. 1008) is not “the same or substantially the same art” that was previously presented to the Office (Ex. 1007).” slip op. at 10

      “On the fully developed record, we find that Petitioner’s construction, “a layer that adheres,” is more strongly supported by the evidence than Patent Owner’s construction, “a pre-formed layer that is adhered.” Our analysis begins with the claim language. The term “adhesion layer” appears in each of the ’806 patent’s independent claims, which include both method and device claims. See, e.g., Ex. 1001, 13:44–63 (claim 1 directed to a “semiconductor device”); id. at 17:58–18:17 (claim 30 directed to a “method of manufacturing a semiconductor device”). Claim 1 recites “a first semiconductor chip having a first adhesion layer adhered to its back surface” and “a second semiconductor chip having a second adhesion layer adhered to its back surface.” Id. at 13:49–51, 13:54–56 (emphasis added). Claim 30 recites the steps of “forming a first insulating adhesion layer on a back surface of a first wafer” and “forming a second insulating adhesion layer on a back surface of a second wafer.” Id. at 17:60–62, 18:3–5 (emphases added). In the absence of contrary evidence, we must assume that the term “adhesion layer” has the same meaning in all claims of the ’806 patent. In re Varma, 816 F.3d 1352, 1363 (Fed. Cir. 2016) (“the principle that the same phrase in different claims of the same patent should have the same meaning is a strong one, overcome only if ‘it is clear’ that the same phrase has different meanings in different claims,” quoting Fin Control Sys. Pty, Ltd. v. OAM, Inc., 265 F.3d 1311, 1318 (Fed. Cir. 2001)). The language of claim 30 and similarly worded claims of the ’806 patent suggests strongly that an “adhesion layer” may be formed in situ on the back surface of a wafer and need not be pre-formed, as argued by Patent Owner. The testimony of Patent Owner’s expert, Mr. Elenius, supports this interpretation. See Ex. 2014 ¶¶ 43, 50 (testifying that a person of ordinary skill in the art “would recognize that there are multiple methods of forming an ‘adhesion layer’ on the back surface of the semiconductor chip” and that “[p]astes and other adhesives, adhesive agents, adhesive layers or other material that are dispensed onto a substrate or chip back are formed into a layer over time as they harden through curing” (emphasis added)). Thus, the language of claims 30 and 31 does not support Patent Owner’s construction that the “adhesion layer” must be a pre-formed layer that is adhered. Cf. PO Resp. 22–25 (arguing for that construction).” slip op. at 17

      “Citing testimony from Dr. Suhling, Petitioner asserts that a person of ordinary skill in the art at the priority date of the ’806 patent would have had i) a bachelor-level degree in electrical engineering, mechanical engineering, material science, or a related subject and five or more years of experience working in the field of semiconductor packaging; ii) a Master’s-level degree in mechanical engineering, electrical engineering, material science, or a related field, and at least 1-3 years of experience in the design/development of semiconductor packages; or iii) a Ph.D.- level degree in mechanical engineering, material science, electrical engineering, or a related field, and at least some experience in the area of semiconductor packaging. Pet. 17–18 (citing Ex. 1002 ¶¶ 28–32). Petitioner further states that “[a]dditional education may substitute for professional experience, and significant work experience may substitute for formal education.” Pet. 18. Patent Owner’s declarant, Mr. Elenius, states that a person of ordinary skill in the art would have had “a bachelor’s degree in electrical, mechanical or materials engineering and two to three years of experience in the design or development of semiconductor manufacturing, or the equivalent.” Ex. 2014 ¶ 32. Mr. Elenius further states that “[a]dditional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education.” Id.

      “3. Reasons to Combine Petitioner contends that it would have been obvious for a person of ordinary skill in the art to combine Ball’s teachings of stacking chips with Mostafazadeh’s process for applying adhesive to create individual chips with adhesive backsides. Pet. 28–29. Petitioner contends that a person of ordinary skill would have been motivated to combine the teachings of Ball and Mostafazadeh for several reasons, including to provide a more efficient manufacturing process for multichip modules and to simplify the stacking process. Pet. 28–31. Patent Owner argues that a person of ordinary skill would not have been motivated to combine Mostafazadeh with Ball because there would have been no reasonable expectation of success and the combination would not have resulted in a functioning semiconductor device. PO Resp. 39. Patent Owner asserts that Petitioner’s combination of Ball and Mostafazadeh would fail for multiple reasons and that Mostafazadeh does not describe multi-chip stacked mounting. Id. at 39–52. Having considered the evidence and arguments, we determine that the preponderance of the evidence favors Petitioner. Petitioner demonstrates persuasively that a person of ordinary skill in the art would have had reasons to combine Ball’s stacked multichip module with Mostafazadeh’s process for applying adhesive at the wafer stage and then dicing to create individual chips with adhesive backsides. Pet. 28–31. In particular, Petitioner shows that a person of ordinary skill in the art would have considered Mostafazadeh’s teaching of applying the adhesive to a wafer surface and then subsequently dicing the wafer in order to provide a more efficient manufacturing process for multichip modules and to simplify Ball’s process of stacking chips. Id.; see KSR, 550 U.S. at 417 (stating that the “mere application of a known technique to a piece of prior art ready for the improvement” suggests obviousness). The teachings of both Ball and Mostafazadeh support Petitioner’s combination. Ball teaches a stacked multichip module using flip-chip and wire bond interconnections, where a lower chip is flip-chip connected to a substrate using metal bumps, and an upper chip is wire bond connected to the substrate. Ex. 1005, Abstract, 3:42–64, 4:58–59, 5:3–12, 5:18–20, 5:23– 27, Fig. 1. Ball teaches that the upper chip is attached to the lower chip in a back-to-back arrangement with a layer of adhesive applied over a back side of the lower chip. Id. Mostafazadeh teaches a method for applying integrated circuit dies to support surfaces. Ex. 1003, Abstract. In Mostafazadeh’s method, an adhesive coating is formed on a surface of a semiconductor wafer, the adhesive coating is dried, and the semiconductor wafer is diced to form integrated circuit dies, each having an adhesive layer on its mounting surface, i.e., its back surface. Id. at 3:5–11, 5:20–25, 7:9–11, 7:29–8:2, Fig. 2 (steps 104–110). A selected die is then attached to an associated support surface by placing the adhesive layer of the selected die in contact with the associated support surface. Id. at 3:11–13, 8:10–12, Fig. 2 (steps 112–118).” slip op. at 33

      “After considering the parties’ arguments and evidence, we determine that Petitioner meets its burden of proof for claim element [3d]. Our finding is supported by Figure 1 of Ball, which depicts a second chip mounted to a first chip in a back-to-back arrangement. Ex. 1002 ¶ 158; Ex. 1005, Fig. 1. More particularly, Ball’s Figure 1 shows that back side 32 of upper die 12 (the claimed “second semiconductor chip”) is mounted to back side 30 of lower die 14 (the claimed “first semiconductor chip”) by adhesion layer 28. Ex. 1005, 5:18–20. Relying on Dr. Suhling’s testimony, Petitioner shows persuasively that “a circuit is formed on the front surface 34 of upper die 12 . . . , as evidenced by bonding pads 36 and wires 38 connecting the upper die’s circuitry to the wiring layer on substrate 16.” Pet. 41; Ex. 1002 ¶ 159. We credit Dr. Suhling’s unrebutted testimony that, “[b]ecause the circuitry is on the front side of upper die 12, a [person of ordinary skill in the art] would know that the back surface adhesive layer is ‘where a circuit is not formed.’” Ex. 1002 ¶ 159. Patent Owner argues that, to meet claim elements [3b] and [3d], “a reference must show that an adhesion layer extends to cover the entire back surface of the second semiconductor chip where a circuit is not formed.” PO Resp. 30. We find no support in the claim language or other intrinsic evidence for Patent Owner’s argument. In our view, the phrase “back surface where a circuit is not formed” identifies the back side of the chip as opposed to the front side, where a circuit is formed. Ex. 1001, 14:26–27 (claim element [3d]). Our interpretation is supported by the claim language as a whole. Claim element [3b], for example, recites “a first semiconductor chip having a circuit forming on its front surface and an adhesion layer adhered to its back surface.” Id. at 14:17–19 (emphasis added).

We are also persuaded by Dr. Suhling’s testimony that the “combination of Ball, Fogal, and Mostafazadeh would require no modification of the multichip modules in Ball and Fogal: rather Mostafazadeh merely explains in more detail methods known in the art for creating chips with adhesive surfaces.” Ex. 1002 ¶ 239; see also id. ¶¶ 62– 69 (describing prior art methods for applying adhesive to the backside of a wafer).

      “Mostafazadeh, could overflow.” PO Resp. 41, 42 (citing Ex. 2014 ¶ 121). According to Patent Owner, the downward pressure during mounting “could cause adhesive to squeeze out.” Id. at 41. We find that Patent Owner’s argument and the corresponding testimony of Mr. Elenius are speculative and do not outweigh Petitioner’s evidence of obviousness. The overflow issue was recognized and addressed by Mostafazadeh. Contrary to Patent Owner’s argument, Mostafazadeh provides explicitly that its adhesive layer “covers an entire mounting surface 190 of the selected integrated circuit dies 182 and does not extend beyond a boundary of the mounting surface 190.” Ex. 1003, 10:6–9 (emphasis added). Additionally, Mostafazadeh teaches that when “the adhesive layer is rolled on, it is exactly the same size as the mounting surface and is quite even. Thus, when the die is attached to its supporting surface the adhesive does not extend beyond the mounting surface of the die.” Id. at 9:15–18. Further, Mostafazadeh teaches that its process avoids the adhesive jutting around the edges of the die. Id. at 2:26–28. These teachings support that a person of ordinary skill in the art would have had a reasonable expectation of successfully applying Mostafazadeh’s die attachment method to Ball’s multichip device while avoiding adhesive overflow. Next, Patent Owner argues that Petitioner’s combination would fail” slip op. at 40

Examples of predefined parameter thresholds include an excessive number of wireless devices in an area, excessive use of wireless devices in an area, two highly dense clusters of wireless devices converging at a significant rate of speed, and the difference in the number of wireless devices in an area exceeds a threshold over consecutive time periods.
