“Patent Owner also asserts prejudice for “not knowing” which Suga Exhibit “the Petitioner and Petitioner’s expert is relying on (see Exhibit 1021 and 1022),” without further explanation. Mot. Reply 6. Exhibit 1022 is a dictionary definition of “node.” How this relates to Patent Owner’s argument of prejudice is not explained. Id. at 5–6. The Board perceives no difficulty following Petitioner’s arguments and evidence, which cite Suga Exhibit 1005, including the testimony of Dr. Buehrer regarding the English language translation of Suga, which is identical in Exhibits 1005 and 1017. Patent Owner, moreover, opted not to depose Dr. Buehrer, did not file a deposition transcript of Dr. Buehrer in this proceeding, and does not allege any difference or substantive deficiency in the English language translation in Suga Exhibits 1005 and 1017, which are identical.

“information” should be given its plain and ordinary meaning as “data,” and that Patent Owner’s narrower construction of “first information” and “second information” lacks sufficient support in the intrinsic record. We agree with Petitioner that the ’802 patent Specification defines “information” as data when it uses the phrase “information (i.e., data).” See Ex. 1001, 5:60–62 (“Information (i.e., data) to be transmitted may be received in a baseband digital system 250, such as a wireless digital baseband processor.” (emphasis added)), 11:30–32 (“In this example, the signals 911 and 912 carry the same information (data).” (emphasis added)).

“argument based on Fernandez alone, we find that Petitioner has not provided a sufficient evidentiary basis to support a motivation to remove the amplification from each of Fernandez’s signal generators 10A-10E and add a single power amplifier instead. See Pet. 76–77 Ex. 1003 ¶ 235. Petitioner’s only rationale for this modification to Fernandez is that “[a] single amplifier has several advantages compared to multiple amplifiers, including lower complexity, a single (vs. multiple) potential point of failure, and lower cost,” and that one of ordinary skill “would have found a single amplifier to be a simple matter of design preference.” Pet. 76–77. Dr. Almeroth simply repeats these cursory allegations without providing any further explanation or evidentiary support. Ex. 1003 ¶ 235.

See Ex. 2013 ¶¶ 99, 104–105. For example, Dr. Cooklev testifies that a single amplifier would need to have a wider bandwidth than the multiple amplifiers used in Fernandez, which could cause potential stability issues.

“We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35

“The claim language and specification define and describe an “activation cue” in functional terms: a data communication from an external source is received by the cell phone and recognized as an activation cue if it causes the switching element to be assigned its first (activated) state.

“operatively linked to said electronic circuit” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. We note there is no presumption of applying means-plus-function analysis to the switching element, because the limitation does not use the words “means for” that would mandate such claim construction treatment, and “switching” may invoke structure as well as function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349–1350 (Fed. Cir. 2015) (en banc) (holding that “use of the word ‘means’ creates a presumption that § 112, ¶ 6 applies”). Regardless, we look to the meaning of the claim phrase at issue in view of the specification. We determine that the ’294 patent provides a clear, concise meaning for the switching element upon which both parties rely for construction. Patent Owner’s express agreement with Petitioner, that the claimed switching element is described in the ’294 patent as “any type of device allowing data to be conveyed according to alternate data conveyance operations in response to an activation cue being received by transceiver 18 or not,’” is particularly telling because it is not consistent with Patent Owner’s argument that the switching element means “switching of the data.” Resp. 7, 31 (citing Ex. 1001, 9:28–318). The claim language does not recite, and the specification does not describe, the switching element as a device that switches the data. Therefore, we determine the claimed “data conveyance switching element” means any type of switching device that allows data to be 8 We presume Patent Owner’s citation to “Exh. 2001, 9:28-31” on page 7 was intended to be a citation to the ’294 patent (Ex. 1001), as cited on page 31. whether or not an “activation cue” is received by the cell phone “cue receiver.”” slip op. at 21

“[external] data exchange device” as a device with a data transceiver coupled to a circuit that carries out the function of exchanging data. Pet. 7–8 (citing Ex. 1001, 2:14–17, 4:7–14, 9:3–6; Ex. 1003 ¶¶ 67–68). As above, whether we construe the “[external] data exchange device” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. Patent Owner, quoting the description of a data exchange device in the ’294 patent, contends that a “[external] data exchange device” “can be any sort of data exchange device comprising an electronic circuit (not shown) therein and a data transceiver 9a.” Resp. 8 (quoting Ex. 1001, 9:4–6). Patent Owner also responds to the Petition by clarifying that “[a]n external data exchange device is not a transceiver but a device with a transceiver.” Id. (citing Ex. 2001 ¶ 48). Petitioner argues in reply that Patent Owner does not contest Petitioner’s mappings of Mooney’s “cordless telephone base unit” or “cellular network infrastructure” to the claimed data exchange devices, such that no construction is necessary to resolve the dispute. Reply 5 (citing Resp. 16–37; Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011)). Limitations [1.c] and [1.d] recite “a first [second] data transceiver operatively linked to said electronic circuit [in the cell phone],” both of which are defined functionally as “for exchanging data between said electronic circuit [in the cell phone] and a first [second] external data exchange device over a first [second] communication link.” Nothing in the the other independent claims, further limits the form or function of the “[external] data exchange device,” although a device external to the cell phone may invoke additional structure.

Indeed, Petitioner does not argue as much, and claims 2, 9, and 11 all at least recite multiple TCP connections. Notwithstanding, I would reach the same conclusion as my colleagues that Patent Owner is not entitled to a presumption of nexus. I am persuaded by Petitioner’s argument (Pet.

The MOVE Media Player and “Sling TV” cannot be coextensive with the challenged claims here under these circumstances.

This also undermines Patent Owner’s assertions of coextensiveness for claims that all recite “continuous playback.” Otherwise, I agree with my colleagues’ finding that Patent Owner has not adduced significant evidence of direct nexus. Accordingly, I join in my colleagues’ finding that Patent Owner has failed to establish a nexus between the asserted evidence of secondary considerations and the challenged claims.

Petitioner further argues that it would have been obvious to use the H-bridge switch of Rossi as part of the Gregorio actuator drive circuit 16 in the asserted Gregorio-Ramsay combination to periodically switch the polarity of drive signals to electric coil 28 of Gregorio, and thus oscillate magnet 27, under the control of a signal from processor 12 of Gregorio. Pet. 56 (citing Ex. 1003 ¶ 211). Petitioner argues that this combination would have been motivated because Gregorio does not disclose implementation details and therefore one of ordinary skill would have looked toward teachings like Rossi to fill in those details, and that an H-bridge switch was a well-known example circuit for implementing a change in “current flow direction/polarity” for “push” and “pull” actions in a system, and was a simple, cost-effective, and reliable circuit design. Id. at 56–58 (citing Ex. 1020, Abstr., Figs. 4, 6, 1:65–3:54; Ex. 1003 ¶¶ 212–217). Petitioner argues that making this combination would have had a reasonable expectation of success given that it involved known techniques through routine circuit design considerations and software instructions for generating the control signal. Id. at 58 (citing Ex. 1003 ¶ 218). Petitioner further argues that it would have been obvious to modify the Gregorio-Ramsay-Rossi combination, using the control algorithm disclosed in Aldrich, to replace the monitoring technique of Gregorio with that of Aldrich to maintain a resonance frequency by incrementing or decrementing the drive frequency. Pet. 58–59 (citing Ex. 1004, 4:22–28, 4:42–48; Ex. 1021, 2; Ex. 1003 ¶ 219). Petitioner’s expert provides implementation details of Aldrich, including that the Aldrich hill-climb technique would use a Boolean value to indicate whether the frequency was being increased, with local variables set to default values, and use integer values when processing sensor signals. Id. at 59–60 (citing Ex. 1021, 2; Ex. 1003 ¶¶ 220–222). Petitioner argues that these modifications would have been motivated to improve the Gregorio system using the Aldrich feedback algorithm for targeting a resonant frequency, given that the Gregorio approach had shortcomings that required a monitoring period with reduced haptic feedback, receiving weak EMF signals. Id. at 61–62 (citing Ex. 2004, 3:65–5:55, 5:63–65; Ex. 1021, 1–3; Ex. 1003 ¶¶ 223–227). Petitioner argues that making this combination would have had a reasonable expectation of success given that it involved known techniques for improvement to yield predictable results, readily implemented via software executed by the microprocessor.

“supply of power from the power supply to . . . cause the moveable component to oscillate at a frequency . . . specified by one or more stored values” to portions of steps 706 and 708 of the flow diagram algorithm of Figure 7A, as described above. Thus, the control component requires a microprocessor and memory with algorithmic structure including a timing algorithm or similar coding for creating a control output signal that flips to control the direction of current flow through a coil (e.g., coil 514, Fig. 5, coil 626, Fig. 6), where the coil is structure that corresponds to the recited “driving component,” as noted above.10 We adopt the District Court’s conclusion in the Apple litigation that the “control component” structure itself does not require an H-bridge switch, but only requires that the processor generates the “d” inputs configured to operate a switch or other circuit; and further that the structure does not require does not require computing initial default values as specified in step 702 of Figure 7A (i.e., values not specified by a user).

The claims only require the control component to control the power supply to cause oscillation at a specified frequency and amplitude, but do not require the frequency value to be generated before the amplitude value, or vice versa.” slip op. at 17

“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

“In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed.

There is uncontested evidence in the record before us, including the ’124 patent, the Gershman, Pierre, Yavnai, Tao, and Goodwin references, and the background and qualifications of both sides expert witnesses that reflect the knowledge and experience of a POSITA, including knowledge of systems for assessing and transporting poultry in an industrial setting. Patent Owner’s proposed skill level overlaps with Petitioner’s proposed skill level, and any differences would not alter the outcome of this proceeding. Therefore, we adopt Patent Owner’s proposed skill level with two modifications.

“to determine a characteristic [of the chick] . . . [that] manifests in one of two or more possible states, e.g., sex (male vs. female), health (healthy vs. unhealthy), genetic mutation (present vs. not present).” Reply 13 (citing Ex. 1004, 3). The recitation of a generic “database of images” does not distinguish limitation [1.4] from the asserted combination of Gershman-Pierre, particularly in view of Pierre’s disclosure of “a computerized processing process is implemented in order to compare the captured images to reference images,” as asserted in the Petition. Ex. 1004, 3 (emphasis added); see Pet. 23–24 (citing Ex. 1003, 2–5; Ex. 1004, 3, 5). Thus, we find that storage of Pierre’s reference images of male and female wing feathers in a database used for comparison in Gershman’s computerized digital chick image processing system would have been obvious to a POSITA and satisfies limitation [1.4].19 We agree with Petitioner that it would have been obvious and well within the skill level of a POSITA—someone with a Bachelor of Science degree in agricultural, industrial, or electrical engineering and two years of experience in industrial poultry sexing and/or image processing (Resp. 20)—to store reference images as taught by Pierre in a “computerized processing” database. The rationale argued by Petitioner, to organize the collection of reference images for comparison to determine whether the characteristic of interest was present, finds direct support in Gershman and Pierre. Both references disclose comparing digital images of a chick’s wing feathers to reference data (Gershman) or reference images (Pierre) of male and female chick wing patterns. Pet. 23–24; Reply 12–13. Storing digital reference images in a database for comparison to captured digital images is, moreover, a basic and straightforward task in any computerized image processing” slip op. at 44
