“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
- BurdenNot shown unpatentable
“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

“institute an inter partes review. The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition. SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1355–56 (2018). Moreover, in accordance with our rules, “[w]hen 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.” 37 C.F.R. § 42.108(a) (2020); see also PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”). Applying those standards, and upon considering the Petition, the Preliminary Response, and the evidence of record, we determine the information presented shows a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’027 patent. Accordingly, we institute an inter partes review of all challenged claims (i.e., 1–3, 5, 7–9, 11–13, and 15–22) of the ’027 patent, based on the grounds asserted in the Petition.” slip op. at 2

“We disagree with Patent Owner’s contentions that these disclosures indicate that Wilson’s patch would not meet the construction of “barrier material composition.” None of these disclosures even suggests that the base of Wilson’s patch is rigid as Patent Owner suggests. To begin with, the fact that the housing is “more rigid” provides no information about the absolute rigidness of the patch. See Ex. 1009, 9:16–21. As for the disclosure that the patch is contoured (id. at 3:35–67), Patent Owner provides only attorney argument to support its contention that the contour demonstrates that Wilson’s patch must be so rigid that it cannot be meet the claim limitation. In contrast, Petitioner demonstrates that Wilson discloses using the exact same materials described in the challenged patent (see Ex. 1001, 6:33–58 (noting “[e]lastomeric materials useful for forming the intermediate layer 24 include but are not limited to gum rubber, vulcanized natural rubber SBR . . . or comparable materials”); Ex. 1009, 3:49–55 (noting the patch may be constructed from natural rubber (NR), a preferred mixture of chlorobutyl rubber and natural rubber (CR/NR), or a preferred mixture of SBR and natural rubber (SBR/NR)), and provides detailed testimony from its expert to support its contentions (see Ex. 1003 ¶¶ 114–119).

“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. Cir. 1995) (citing Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (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. A POSITA also could have a Bachelor of Science degree in Animal Science or similar discipline, and a POSITA would be familiar with techniques for assessing and transporting poultry in an industrial setting, such as visual and/or anatomical characteristics of a chick.” slip op. at 7

“to determine a characteristic [of the chick] . . .

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.

More education can substitute for practical experience and vice versa. Pet. 10 (citing Ex. 1004 ¶ 34).

“Both parties rely on the language of claim 1 and the ’294 patent specification to support their respective constructions, and they emphasize that a user’s selective triggering of the control device does not issue different activation commands or control which data conveyance operation is used. Claim 1 recites an “invariable activation command” as a command that is “issued when said control device is selectively triggered by the user.” selectively trigger a control device “via one of a button, a keypad, a tactile screen, and a biometric parameter detector,” e.g., by entering a PIN that is authenticated, in order for an invariable activation command to be issued. Id. at 8:43–50, 10:26–29, 19:3–5. The claimed function of an invariable activation command is to “initiate[]” either a “first data conveyance operation” or a “second data conveyance operation” depending on whether “said switching element is in said first state” or “in said second state.” As explained above, the state of the switching element depends on whether or not an “activation cue” has been received by a “cue receiver.” The ’294 patent specification confirms the operation. Id. at 10:26–36, 15:14–28. The parties joust over the proper terminology for characterizing an “invariable” activation command, but they appear to agree on how the claimed cell phone and method work. The ’294 patent specification makes clear that the activation command is “invariable” in the sense that whenever a user selectively triggers the control device on the cell phone, for example by pressing a button on a keypad, the same command is issued to initiate a data conveyance operation regardless of the “state” of the “switching element” (i.e., in a “first state” or “second state”). The user cannot select or issue different activation commands. The selection of which of the two possible data conveyance operations will be initiated by selectively triggering the control device depends not on the activation command—it is always the same—but on whether the switching element has received an activation cue (“first state”) or not (“second state”). The ’294 patent neatly summarizes that “[t]he same invariable activation command will thus be issued upon [the] control device being triggered, and it is the state of [the]” slip op. at 12

“The ’294 patent claims and specification make clear that the switching element switches between a “first state” and a “second state” depending on whether or not an activation cue is received. Ex. 1001, 9:28–41, 14:53–59. The state of the switch, in turn, “allow[s] data to be conveyed according to alternate data conveyance operations.” Id. (emphasis added). Thus, the claim limitation is recited as a “data conveyance switching element,” not a “data switch,” because the switching element allows the device to switch between alternate operations for conveying data from the cellular phone to an external data exchange device. Id. Patent Owner’s proposed construction “conflicts with the express disclosure of the ’294 Patent.” See Phillips v. AWH Corp., 415 F.3d 1303, 1315 (Fed.

However, the open-ended language “at least” expands the range of education and experience indefinitely with no upper bound. Therefore, we do not adopt this aspect of Petitioner’s formulation. Although we adopt Petitioner’s definition of a person of ordinary skill in the art, our determination regarding Petitioner’s challenge does not turn on the differences between Petitioner’s and Patent Owner’s definitions, and our conclusions would be the same under either definition.

“Although the specification broadly defines “module,” the language of the claims better supports Patent Owner’s argument that the computer program module limitations connote structure in the form of software instructions or code. Prelim. Resp. 13–14 (citing Ex. 2001 ¶¶ 22–24; Ex. 2003 ¶¶ 15–28). Specifically, claim 1 recites a computer-readable storage medium storing computer program modules configured to execute on the computer processor, the computer program modules comprising. . . a monitoring module . . . a first relevance measurement module . . . a second relevance measurement module . . . and a relevance analysis module.

“Second, the key differences between Petitioner’s and Patent Owner’s proposed qualifications for a person of ordinary skill in the art at the time of the invention is that Patent Owner asserts “experience in wireless telecommunications and cellular technology is necessary,” as well as a background in radio frequency communications and/or navigation system technology with two years of industry experience working in the same, would be required. PO Resp. 22–23 (citing Ex. 2018 ¶ 46); see also id. 44– 45. The ’104 patent is directed to locating a wireless mobile device in a geographic region. Ex. 1001, 1:13–20; PO Resp. 44.

“In this case, Patent Owner attempts to make much of Dr. Sundaresan’s statement that he had been informed of the qualifications of a person of ordinary skill in the art. See PO Resp. 41–43. Dr. Sundaresan’s testimony, however, set forth this understanding of the requisite level of skill in the art (Ex. 1003 ¶ 8). In his supplemental declaration, Dr. Sundaresan further testifies that: I agreed with this POSITA definition when preparing the Declaration, and I continue to hold the opinion that the POSITA definition is both correct and appropriate based on the disclosures of the ’104 patent and the prior art analyzed in the Declaration. Ex. 1055 ¶ 17. Dr. Sundaresan further testifies that “[i]f I did not agree with the POSITA definition, then it would not have been included in paragraph 8 of the Declaration.” Id. ¶ 18. Dr. Sundaresan’s inclusion of the definition of the level of ordinary skill in his original declaration indicates that he agrees with the definition, as confirmed by his cited subsequent testimony.

“explained below, we agree with Petitioner that Patent Owner’s additional requirement of evaluating the calibration data to determine the boundaries of the area represented by a grid point should not be included in the construction of either “grid point” or “non-uniform grid point.” Instead, based on the full record, we discern no reason to alter our prior construction of “grid point” as “a point associated with representative calibration data for an area” and maintain that construction for this Final Written Decision. The construction of “grid point” we adopt is supported by the Specification of the ’104 patent. Namely, the ’104 patent discloses that “[i]n general, a non-uniform grid point (NUG) may represent the signal characteristics and/or calibration data over a given region,” and “NUGs represent an area of collected calibration data.”18 Ex. 1001, 3:50–60. The district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 2018, 3:56–60) as “provid[ing] a clear indication of the meaning of ‘grid point.’” Ex. 2012, 19 (emphasis added). We agree with the district court’s analysis. Although the ’104 patent does not explain how a generic “grid point” might differ from the described “nonuniform grid point,” we do not find this distinction pertinent to construing “grid point” in this case because neither party raises this issue. Also, based on the claim wording “non-uniform grid point,” a “non-uniform grid point” is a type of grid point. See Pet. Reply 3 (explaining why that plain meaning supports Petitioner’s proposed construction). Furthermore, the district court construed “grid point” only, not “non-uniform grid point.” Ex. 2012, 18–20.” slip op. at 27
