“The parties agree that independent claim 2 includes means-plus- function limitations under 35 U.S.C. § 112 ¶ 6.8 Pet. 2–6; PO Resp. 7–15. An element in a claim for a combination may be expressed as a means . . . for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. 35 U.S.C. § 112 ¶ 6. In particular, the parties agree that the “driving component” and “control component” requirements of independent claim 2 are means-plus-function limitations. Pet. 2–6; PO Resp. 7.

“Petitioner’s expert declarant contends that a person of ordinary skill in the art (POSITA) would have had a degree in mechanical engineering, electrical engineering, physics, or a related technical field, and at least 2–3 years of experience related to the design or development of systems incorporating linear actuators; additional years of experience could substitute for the advanced-level degree. Ex. 1003 ¶ 30. Patent Owner offers “a similar level of ordinary skill in the art.” See PO Resp. 4.

“In contrast to Petitioner’s showing, at the passage cited by Patent Owner, Dr. Goossen, Patent Owner’s expert, does not provide a basis for his opinion that “the combined system of Gregorio-Ramsay-Rossi-Aldrich does not teach the claimed output to the power supply.” Ex. 2009 ¶ 156; PO Resp. 21 (citing Ex. 2009 ¶ 156). To the extent Dr. Goossen addresses the issue, like Patent Owner, Dr. Goossen concedes that “a POSITA would recognize in the [annotated drawing of Gregorio supplied by Petitioner] that a power supply is required that is not shown.” Ex. 2009 ¶ 116. And also like Patent Owner, Dr. Goossen concludes that Petitioner’s rationale that an “unshown power supply receives a signal from the processor is a sweeping conclusion that does not follow.” Id. For the reasons discussed above in connection with Patent Owner’s parallel arguments, this testimony is conclusory and unsupported. Primarily, it does not adequately address Petitioner’s showing and Dr. Hannaford’s testimony, discussed above, which relies on Gregorio’s statement that “[p]rocessor 12 outputs the control signals to drive circuit 26 which includes electronic components and circuitry used to supply LRA 18 with the required electrical current and voltage to cause the desired haptic effects.” Ex. 1004, 2:36–39 (emphases added). Dr. Goossen and Patent Owner also do not address the initial finding in the Institution Decision that “[t]he ’337 patent does not disclose any detail or structure for the controllable power supply, indicating that such a controllable power supply was well-known.” Inst. Dec. 30 (citing Ex. 1001, 6:33–35 (“The power supply 612 receives a control input 624 from the CPU to control the current supplied to the H-bridge switch for transfer to the coil 626.”)).16 And while Dr. Goossen contends that Dr. Hannaford’s reliance on Ramsay to further suggest control of the power supply is conclusory because “Dr. Hannaford’s statement about ‘the current provided from a power supply to the driving component’ has nothing to do with Ramsay’s disclosure,’” Dr. Goossen addresses Ramsay and Gregorio in isolation, without adequately addressing the combination, specifically where Gregorio teaches or suggests controlling a power supply in order to provide desired LRA amplitude and frequency haptic effects, which is in line with Ramsay’s teaching of user-customizable parameters to control amplitude and frequency for the same purpose. See Ex. 2009 ¶ 126; Pet. 53–54 (summarized above). Therefore, the Petition shows persuasively that Gregorio’s processor controls Gregorio’s power supply to provide power to its haptic unit or that such power supply control would have been obvious in view of Ramsay in order to allow a user to control the desired haptic effect.” slip op. at 41

“CLAIM CONSTRUCTION B. In an IPR, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

“At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed.

“II. ANALYSIS A. Institution of Inter Partes Review We instituted an inter partes review in the Apple IPR on all challenged claims and all asserted grounds of unpatentability. Apple IPR, Paper 10 (institution decision); see also Apple IPR, Paper 2 (the “Apple Petition”). Petitioner here challenges the same claims and asserts the same grounds of unpatentability as those on which we instituted the Apple IPR. Compare Pet. 2, with Apple Petition 1; see also Mot. 1 (asserting the instant “Petition is substantively identical to Apple Inc.’s petition (‘Apple Petition’) in the Apple IPR, including that it relies on the same expert declaration,” and asserting “the same grounds presented in the Apple IPR”). As indicated, Petitioner also relies on the same declarant as did the petition in the Apple IPR. Mot. 1; compare Ex. 1003 (Hannaford Declaration), with Apple IPR, Ex. 1003 (same).

Mot. 1, 4. Petitioner represents that “joinder will not negatively impact the Apple IPR trial schedule” and “expressly consents to the existing trial schedule.” Id. at 10; see also id. at 7 (“Proceeding with a consolidated inter partes review would avoid potential inconsistency, promote efficient review of the same claims for the same patent under the same grounds, and would result in a final written decision without delay.”). Petitioner also represents that as “long as Apple remains in the joined IPR, Nintendo remains in a limited ‘silent understudy’ role that does not actively participate in the IPR.” Id. at 8. The record supports Petitioner. In addition, the final written decision in the Apple IPR is due to issue on or before October 15, 2025, with the Oral Hearing complete and no further briefing due. See IPR 2024-00807, Paper 15 (Oral Hearing Transcript); Paper 18, 2–3. Therefore, as Petitioner argues, joinder by Petitioner will have little or no impact on the trial schedule in the Apple IPR. On the other hand, if the Board denies joinder, Petitioner submits that it “intends to file a separate petition for IPR (‘Second Petition’) that includes grounds in addition to some (or all) of the grounds in the Apple IPR.” Mot. 14.” slip op. at 10

“arguments and evidence for purposes of institution that would support determining that a person of ordinary skill in the would have been motivated to combine the teachings of Shin and Aoyama. As one example, Amazon contends that the proposed combination is merely the addition of one known element (i.e., “Aoyama’s natural language processing and information retrieval”) to another known element (i.e., “Shin’s voice processing and response device”) to obtain predictable results (i.e., “identifying a user’s intent and providing information responsive to such intent”). Pet. 19–20 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 83). As another example, Amazon contends the proposed combination also represents the addition of one known element (i.e., “Aoyama’s word replacement” feature) to another known element (i.e., “Shin’s distance-based content abbreviation/simplification”) to obtain predictable results (i.e., “using word replacement to simply content for distant users”). Id. at 25–26 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 100).

“Based on the preliminary record, we discern no deficiency in Amazon’s characterizations of Shin, Aoyama, or the general background knowledge in the art. In addition, for purposes of institution, we are persuaded by Dr. Stern’s testimony concerning the relevant disclosures in Shin and Aoyama. At this stage of the proceeding, SoundClear argues that Shin does not teach limitations 1[b]—“a voice classifying unit configured 1[b][i] to calculate a distance between the user and the output-content control device by a proximity sensor 1[b][ii] to classify the voice into either a first voice or a second voice based on the calculated distance.” See Prelim.

Limitations 1[b]—“a voice classifying unit configured to 1[b][i] calculate a distance between the user and the output-content control device by a proximity sensor to 1[b][ii] classify the voice into either a first voice or a second voice based on the calculated distance” In the Preliminary Response, SoundClear contends that Shin fails to teach voice classification because “Shin is incapable of distinguishing [between] multiple voices.” Prelim. Resp. 21. More specifically, SoundClear argues that Shin cannot teach classifying a voice into a first voice or second voice because “Shin never refers to a ‘first user’ or ‘second user’ or ‘multiple users.’” Id. (citing Ex. 1003 generally); see also id. at 26– 27 (arguing that Amazon misstates the record because Shin never discloses a “first voice” nor a “second voice”). Instead, SoundClear asserts that Shin only contemplates a single user (i.e., user 10) when calculating the distance between the user and an electronic device (e.g., Shin’s electronic device 100). Id. at 21–22 (citing Ex. 1003 ¶¶ 37, 38). Based on the preliminary record, Amazon presents sufficient evidence that would support a finding that Shin teaches “a voice classifying unit configured to calculate a distance between the user and the output-content control device by a proximity sensor to classify the voice into either a first voice or a second voice based on the calculated distance.” Pet. 10–14. Shin discloses that “processor 120 may determine an output scheme of corresponding content based on a distance between a user and the electronic device 101.” Ex. 1003 ¶ 53. Shin’s processor 120 accomplishes this distance calculation by using distance detection module 180, which may include various sensors, such as a proximity sensor. Id. ¶ 66; see also id. ¶ 153 (disclosing an embodiment where electronic device 901 includes sensor module 940, which, in turn, includes proximity sensor 940G). Shin’s Table 3 illustrates how the distance between the user and electronic device 101 determines the output scheme. Id. ¶ 86, Table 3. For instance, Shin’s Table 3 illustrates classifying the user’s voice input as a “first voice” when the distance between the user and electronic device 101 is between 1 to 2 meters, and classifying the user’s voice input as a “second voice” when the distance between the user and electronic device 101 is less than 1 meter.

Moreover, Yamaguchi-727 uses a method for preventing movement of its module 6 in its housing 20, silicone potting material, that is expressly recognized by the Specification of the ’421 patent when it states: “A common technique used to assist in fixturing the electrical sensor device 40 known within the automotive industry is to fill the internal cavity with a coating material such as a neutral silicone or the like for purposes of retaining placement position.” Ex. 1001, 13:56–60. Although the Specification also asserts that the sensor assemblies disclosed in the 421 patent “do not use or require the use of any such coating or filing agents or materials for any fixturing of the electrical sensor device 40,” id. at 13:61–64, limitation 1b merely requires that the “sensor device . . . is disposed within the internal cavity and attached therein to prevent movement of the device within the internal cavity,” id. at 30:25–27.

“B. Level of Ordinary Skill in the Art Petitioner argues that at the time of the ’634 patent (July 2018), a person of ordinary skill in the art would have had “a bachelor’s degree in electrical engineering, computer science, computer engineering, or a similar major with at least two years of experience in the field; or a master’s degree with specialization in the field,” where “[a] person with less education but more relevant practical experience may also meet this standard.” Pet. 7 (citing Ex. 1003 ¶¶ 12–13). Petitioner further argues that a person of ordinary skill in the art would have had knowledge of “[d]esigning and using systems that include endpoint devices (e.g., client devices) and servers for establishing network connections and data transfer,” “[r]ecognizing and applying the client-server architecture,” and “[u]sing and applying concepts from known telecommunication and networking frameworks, protocols and standards, including TCP/IP, IEEE 802.11, VoIP, cellular systems and other known frameworks and standards.” Id. (citing Ex. 1003 ¶ 14). Patent Owner does not address the level of ordinary skill in the art in its Preliminary Response. Based on the record presented, including our review of the ’634 patent and the types of problems and solutions described in the ’634 patent and cited prior art, we agree with Petitioner’s definition and apply it for purposes of this Decision. See, e.g., Ex. 1001, col. 1, ll. 4–29 (describing in the “Background” section of the ’634 patent a “network connection between two endpoints” and known methods of reaching “full effective bandwidth capacity” in a network).” slip op. at 8

“C. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner notes that it proposed a construction for the claim term “geographical area” in the district court case, but states that it “do[es] not believe proposing a construction for the term is necessary in this proceeding because the relied upon teachings of the prior art references are consistent with examples of ‘geographical area’ included in the ’634 patent [S]pecification.” Pet. 8. Patent Owner argues that “[t]he Board need not engage in express claim construction at this stage of the proceeding.” Prelim. Resp. 5. We conclude that no express interpretation of any claim term is necessary to determine whether to institute an inter partes review in this proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (citation omitted) (emphasis added)).” slip op. at 9

“Petitioner has not shown sufficiently that Erskine teaches or suggests the second requirement of limitation [1c], i.e., “initiating the next network connection . . . with a transmission bandwidth based on the parameter values for the past network connection.” Petitioner’s theory is that (1) the QoS parameters in Erskine are for a “past” connection from one zone to another, (2) the sliding maximum interzone bandwidth is “based on” the QoS parameters, and (3) a new call only proceeds if the transmission bandwidth needed for the call added to the current bandwidth being used over the interzone link is less than the sliding maximum interzone bandwidth, so Erskine therefore teaches a call with a transmission bandwidth determined “based on” the sliding maximum interzone bandwidth (which in turn is determined “based on” the QoS parameters). See Pet. 27–28; Ex. 1003 ¶¶ 59–60 (similar testimony from Dr. Crovella). As Patent Owner points out, however, Erskine only makes “a binary, accept/reject decision as to whether to allow a new call to proceed based on a comparison between the bandwidth needed for the call and a predetermined ‘sliding maximum interzone bandwidth value.’” See Prelim. Resp. 6–7. Specifically, the additional bandwidth that would be needed for the call is added to the current bandwidth being used on the interzone link; if the sum of those values is less than the sliding maximum interzone bandwidth for the link, the call “proceeds”; otherwise, it is “blocked.” Ex. 1004, col. 4, ll. 36–40, col. 6, l. 55–col. 7, l. 10, col. 8, ll. 36–43, col. 9, ll. 9–26, col. 10, ll. 23–25 (the sum is compared to the sliding maximum interzone bandwidth “to determine whether enough bandwidth is available to proceed with the new call”), Fig. 3 (steps 308, 310, and 312). Erskine repeatedly refers to the bandwidth for the new call as the amount of bandwidth that is “necessary” or “required” to handle the call. See, e.g., id. at col. 1, ll. 43–57 (“an amount of bandwidth necessary to handle the new call”), col. 6, ll. 61–64 (“the additional bandwidth required (of the new call)”), col. 8, ll. 36–40 (“the bandwidth necessary for the new call”), col. 9, ll. 16–21 (“the anticipated additional bandwidth necessary for the new call”), 54–56 (“the bandwidth amount the new call will utilize (if connected)”), col. 10, ll. 21–23 (same), 41–43 (same), col. 12, ll. 1–2 (“an amount of bandwidth necessary to handle the new call”). It is that value—determined prior to the addition and comparison to the sliding maximum interzone bandwidth—that will be used for the new call if it is allowed to “proceed[].” Id. at col. 6, ll. 64–67 (if the sum is less than the sliding maximum interzone bandwidth, the call “proceeds” and “the QoS table is updated with the additional bandwidth used by that call”). Erskine does not describe the transmission bandwidth for the new call as being based on any parameter values for a past network connection, but rather as “whatever bandwidth the system determined is necessary for the additional call.” See Prelim. Resp. 8–9. In other words, the transmission bandwidth needed for a new call is predetermined and independent of whatever the sliding maximum interzone bandwidth is currently. See id.” slip op. at 15

“repeatedly emphasized that an indefinite article “a” or “an” in patent parlance carries the meaning of “one or more” in open-ended claims containing the transitional phrase “comprising.” That “a” or “an” can mean “one or more” is best described as a rule, rather than merely as a presumption or even a convention. The exceptions to this rule are extremely limited: a patentee must “evince[ ] a clear intent” to limit “a” or “an” to “one.” The subsequent use of definite articles “the” or “said” in a claim to refer back to the same claim term does not change the general plural rule, but simply reinvokes that non-singular meaning. SanDisk Corp. v. Kingston Tech. Co., Inc., 695 F.3d 1348, 1360 (Fed. Cir. 2012) (quoting Baldwin Graphic Systems, Inc. v. Siebert, 512 F.3d 1338, 1342 (Fed. Cir. 2008)). These controlling case authorities are applicable here. At this stage, we preliminarily construe the scope of the claim 1[b] term “a user” as covering one or more users. Likewise, we preliminarily construe the scope of the 1[b] phrase “a voice spoken by a user” as covering one or more voices spoken by a single user, or by plural users.” slip op. at 15
