“establishes that the subject matter of independent claim 19 would have been obvious in view of Whitehead. Claim 19 recites “an aggregator having a memory and a processor, the processor adapted for . . . providing an output signal including data indicative of the selection and of user data.” Ex. 1001, 15:51–16:3. As discussed above (Section II.C.2), we construe claim 19 as requiring a signal including both “data indicative of the selection and of user data.” Accordingly, we consider whether Petitioner has shown that Whitehead teaches or suggests that the “aggregator” “provid[e] an output signal including” both “data indicative of the selection and of user data.”” slip op. at 46

“Cristofalo’s “user identifiers” represent data about users that Cristofalo’s system uses to “select a specific media object” (advertisements) from received “multi-object programming data.” Cristofalo at ¶ [0048]. For example, a user identifier may indicate that a given user is a Coca-Cola drinker, and when the receiving system receives the multi-object programming data it can select a particular media object out of several possible media objects (e.g., a Pepsi advertisement) to push to the user. Id. This user data exists independently of, and does not relate to, any particular media stream or streams. See Goodrich PO Resp. Decl. at ¶ 135. Petitioner seems to recognize this when tersely referring to “user identifiers” as “data,” not “data relating to a plurality of streams.” Pet. at 71.

“The parties’ definitions are similar, although we observe that Patent Owner proposes that the person of ordinary skill would have a bachelor’s degree or an equivalent or professional experience, whereas Petitioner proposes that such a person would have both a degree and experience. Neither party presents any arguments relating or referring to the level of ordinary skill in the art. Determining the level of ordinary skill in the art involves various factors, 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.

We adopt Petitioner’s assessment of the level of skill in the art. Petitioner’s assessment is supported by the testimony of Dr. Almeroth and is consistent with the ’753 patent and the asserted prior art. However, our obviousness analysis would be the same under either party’s assessment.

Petitioner supports this contention by articulating the following reasons for the asserted modification of Whitehead’s mixing server 130 to incorporate Marcus ’904’s algorithm: “makes it more likely the system will identify content best suited for a particular user,” “allows for more targeted advertising and/or an opportunity to maximize revenue,” “improves Whitehead’s ability to target content and advertising to a particular user,” “would unlock new revenue sources for Whitehead,” “Marcus ’904’s content selection and concatenation algorithm improves Whitehead’s efficiency,” “[b]oth Whitehead and Marcus ’904 generate custom media programming based on a user profile,” “incorporating Marcus ’904’s teachings would not require redesigning Whitehead’s architecture and instead merely supplements Whitehead’s disclosure,” and “Petitioner’s proposed modification can be implemented entirely in software and does not require any hardware modifications.

“Patent Owner (PO Resp. 12, 49–50) points to the Specification’s list of “[e]xamples of power reduction actions.” Ex. 1001, 8:47–63. Patent Owner asserts that the list includes numerous examples of power reductions that occur in the present and one that takes place in the future—namely, “scheduling nonessential operations at a different time (e.g., nonessential software or hardware upgrades).” Ex. 1001, 8:61–62 (cited at PO Resp. 12, 50). We are persuaded by Patent Owner’s contention (PO Resp. 12) that the applicant, by including the term “current” in the claims, intentionally narrowed the claims to power consumption reductions that occur temporally in the present, rather than those that occur in the future. See Pet. Reply 6–7 (Petitioner asserting that Patent Owner’s position is “inconsistent with the specification’s examples,” but then arguing that the Specification does not support that position rather than pointing to any purported inconsistencies).

“Given the interchangeable nature taught for various features of Wang’s embodiments, it would have been a routine and obvious matter for a POSA to combine aspects from Wang’s various embodiments (e.g., data acquisition, internal hardware, data analysis performed by the UMC receiver 400 and/or the display 200). Moreover, many of Wang’s embodiments–particularly of specific smart appliance types– include common components, thus further confirming combinability of aspects of the disclosed embodiments. A POSA would have had a reasonable expectation of success in combining features of the embodiments together. Id. at 77–78 (citing Ex. 1003 ¶¶ 201–203). We determine that these reasons are inadequate and too generic to satisfy Petitioner’s burden as they lack a clear explanation of what and how “aspects from Wang’s various embodiments” are proposed to be combined along with reasoning specific to that proposal.

“We are not persuaded that the Specification evidences a clear intent by the patentees to redefine (either explicitly or by implication) or to otherwise narrow the scope of the claim terms “request” and “response,” as Patent Owner urges. The statements in the Specification upon which Patent Owner relies are referring to “Request 414” and “Response 418.” See PO Resp. 27 (quoting Ex. 1001, 12:3–4, 12:12–14). As indicated by the reference numbers, the Specification is discussing a specific request and a specific response in the context of Figure 4, which is described as depicting “an illustrative embodiment.” See Ex. 1001, 10:51–53 (“FIG. 4 is a system for managing a charging process of an electric vehicle in accordance with an illustrative embodiment.”), 12:1–19, Fig. 4. By stressing the illustrative nature of the embodiment of Figure 4, the patentees indicated an intent for it to not be limiting. See also Ex. 1001, 15:44–47 (the Specification stating: “The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed.”); Hill-Rom Servs., Inc., 755 F.3d at 1373 (“[T]hose terms [including, datalink 39] are used synonymously only in describing a particular numbered component in the figure depicting the preferred embodiment, and never in describing the datalink of the invention generally.”). At oral argument, Patent Owner’s counsel, relying on the opinion of Dr. Cameron, argued that a person of ordinary skill in the art would “read the definition without the reference numbers.” Tr. 43:23–44:9. Thus, we understand Patent Owner to argue that the Specification provides an explicit definition when one reads out a portion of the Specification—converting, for example, “Request 414 is a message” to “Request is a message.” This is not persuasive as it involves editing the evidence to conform to Patent Owner’s argument, rather than an argument supported by the Specification as written by the patentees. Patent Owner does not direct us to any portion of the Specification that clearly defines “request” and “response” generally or, for example, uses phrasing implying that those terms are defined for “the present invention.” See, e.g., Hill-Rom Services, Inc., 755 F.3d at 1372 (“For example, we have held that disclaimer applies when the patentee makes statements such as “the present invention requires . . .’ or ‘the present invention is . . .’ or ‘all embodiments of the present invention are . . . .’”); Astrazeneca, 384 F.3d at 1339 (discussing defining by implication and determining that the “specification’s statement that ‘[t]he solubilizers suitable according to the invention are defined below’ provides a strong signal of lexicography.”).” slip op. at 17

“We fail to discern a clear disparagement of the use of signals in the Specification that would justify excluding signals from the scope of the claimed invention. The Specification does not mention in these excerpts the use of signals, and thus does not characterize “using signals as less ‘complete, flexible, and interoperable,’” as Patent Owner impliedly argues. PO Sur-reply 11. The Specification characterizes “the most rudimentary charging scenarios” as including situations such as a car owner merely plugging the electric vehicle into a common electric outlet at the owner’s house, and suggests that illustrative embodiments are an improvement in that they apply to “much broader and more complex sets of circumstances than this simple scenario.” See Ex. 1001, 6:60–7:2. An example of a “complex transaction[]” is the car owner using a charging station located away from the owner’s house and being required to pay for the charge. See id. at 7:2– 11. To the extent there is any disparagement, it is merely of the simple scenario of the owner plugging the car into the standard household outlet. Cf. Epistar Corp. v.

We find that Petitioner’s assertion—that a person of ordinary skill in the art would be motivated by a desire to assure a safe and commercially-desirable system (Pet. 53)—to have rational underpinning. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Patent Owner argues that Dr. Cameron “explained [that] . . . it would not be simple because Hotta uses two-stage charging subroutines.” PO Sur-reply 16 (citing Ex. 2005 ¶ 118). We disagree with Patent Owner’s characterization of Dr. Cameron’s testimony. The cited paragraph 118 states that Hotta’s figures depict “two-stage charging subroutines different from both the ’391 patent and Kimura,” and that there are “fundamental differences.” Ex. 2005 ¶ 118. Dr. Cameron does not go so far as to opine that combining the teachings as Petitioner’s proposes would not be considered simple by a person of ordinary skill in the art. See id.; see also Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007) (“Leapfrog presents no evidence that the inclusion of a reader in this type of device was uniquely challenging or difficult for one of ordinary skill in the art.”). Dr. MacCarley, on the other hand, credibly testifies that “making use of Hotta’s command keys in Kimura’s system . . . would have been a simple substitution of one known element (Kimura’s lightly- described main switch) for another known element (Hotta’s command keys) to achieve predictable results (a charging process that can be stopped by pressing Hotta’s charging stop command key . . .).” Ex. 1009 ¶ 147.

“May” expresses a possibility. The Specification reflects this interpretation of “may” when it states that “[i]n one embodiment, the organic material is not lyotropic. Thus, the organic material may not be a phospholipid.” Ex. 1001, 8:27–28 (emphasis added). One of ordinary skill would understand from this that the organic material “may not be” a phospholipid if the organic material is not lyotropic. It follows that if the organic material is lyotropic, then the organic material may be a phospholipid. Reading the statement “[t]he organic material may not be . . . a phospholipid” (id. at 8:59–63) in light of the earlier stated possibility that the organic material may be a phospholipid if the organic material is lyotropic, one of ordinary skill in the art would interpret “may not be” as excluding phospholipids under some conditions, not under all conditions. Taking the Specification’s discussion about phospholipids as exemplifying the permissive nature of the word “may,” we are unpersuaded that in stating that “[t]he organic material may not be [PMMA], a polyvinylidene difluoride-containing polymer, such as [PVDF] or PVDF- TrFE-CTFE, or a phospholipid, such as [DHPE]’” (Ex. 1001, 8:59–63), the specification “contains a clear and unmistakable disavowal of the compounds PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE” and “disclaims the listed compounds” from the “organic material” of the claims under all conditions, as Patent Owner argues. Prelim. Resp. 6–7. Moreover, the claims themselves limit the “organic material” only to the extent that it is “barocaloric cooling or heating agent” and can perform in the manner claimed. See Ex. 1001, claim 1, supra. As broadly worded, the claims do not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE per se from the group of organic materials employed by the claimed method. Adopting Patent Owner’s construction would impermissibly import a limitation (i.e., not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE) into the claims. For the reasons stated, at this stage of the proceeding, we agree with Petitioner’s broad construction of “organic material.” We do not adopt Patent Owner’s proposed construction whereby PMMA, PVDF, PVDF- TrFE-CTFE, and DHPE are excluded from the scope of the claim term “organic material.” The parties are invited to address this issue further during trial, if desired. slip op. at 11

“Petitioner shows that (a) Mañosa (i.e., inorganic compounds such as Ni-Mn-In, Gd5Si2Ge2, and La-Fe-Co-Si) and (b) Patel (i.e., PVDF-TrFE- CTFE) teach materials exhibiting inverse BCEs.

“Since the parties apply what they contend is the plain and ordinary meaning of the claim terms in their briefs, and have stipulated in the Cox case that the plain and ordinary meaning applies, and Patent Owner argues that the district court’s construction in the Charter case is the plain and ordinary meaning, there is no controversy concerning claim terms that we need to resolve in this Decision. Pet. 6; Prelim. Resp. 10; Ex. 1005, 104–105; Ex. 2001, 2. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

At this stage of the proceeding, therefore, we apply the plain and ordinary meaning to the claim terms consistent with their ordinary and customary meaning under 37 C.F.R. § 42.100(b). We note, however, that Patent Owner seems to consider the court’s construction in the Charter case to require that the claimed “probe” must be of a type that can be compared with a reference signal. Prelim. Resp. 10. We question whether all of the different types of probes mentioned and claimed in the ’690 patent would require comparison with a reference signal. See, e.g., Ex. 1001, 2:7–19.

“Prelim. Resp. 23 (citing Ex. 1013, 37) (annotated in red by Patent Owner). IEEE-802.16’s Table 5 shows that the CID is a field of a generic MAC header. Petitioner does not show sufficiently that the CID, located in the header, specifies content payload of a MAC message, as required by limitation 1A. Petitioner alternatively relies on IEEE-802.16’s ranging code index that it contends is another example of data that is in a ranging request parameter and is used for the ranging response payload. Pet. 15 (citing Ex. 1013, 49–51, 204–213, 576–579, 665–66; Ex. 1002 ¶ 149). Patent Owner asserts that the portions of IEEE-802.16 that Petitioner cites do not disclose that the ranging code index is sent as part of a ranging request message. Prelim. Resp. 25. Although the parts of IEEE-802.16 that Petitioner cites disclose that the ranging code index is sent from the SS to the BS and is included in a ranging response (Ex. 1013, 49–51, 204–213, 576–579, 665–66), the cited parts do not disclose that the SS sends the ranging code index to the BS in a ranging request. Consequently, Petitioner has not established that IEEE- 802.16 anticipates a ranging code index that is a parameter of a ranging request specifying the content payload of the ranging response corresponding to limitation 1A. For the foregoing reasons, on this record, we determine that Petitioner has not shown a reasonable likelihood to prevail in showing that claim 1 is anticipated by IEEE 802.16.” slip op. at 18

“As an initial matter, the recited expression “mounted to” is broad. The Federal Circuit has explained that words in a claim “will ordinarily be given their full meaning,” without imposing narrowing modifications on the claim language. Johnson Worldwide, 175 F.3d at 989, see also Virginia Panel, 133 F.3d at 865–66. As to whether the “mounted to” connection may be an indirect connection, the parties agree that an indirect connection is permitted — a view that is amply supported by the intrinsic record, as discussed above. With regard to the types of movement that may occur between a “string guide” and a corresponding “limb,” the intrinsic record shows that that various types of movements (including no movement at all) are characterized as “mounted to.” Slight variations of “mounted to,” occurring in the intrinsic record, are helpful in understanding the claim language — particularly because the ’015 patent itself uses such a variant (“mounted . . . on”) to describe the very connection (between a “string guide” and a “limb”) that is elsewhere, and in claim 1, is described as “mounted to.” See Ex. 1001, 5:23–26.” slip op. at 22

“Patent Owner’ sole argument — i.e., that Stanziale ’771 fails to teach the “mounted to” limitation — is based upon its construction of the “mounted to” limitation, which permits the “string guide” to be rotatable relative the corresponding “limb,” but permits no other type of relative motion. See PO Resp. 4, 13–14. As discussed above, we do not accept Patent Owner’s construction of the “mounted to” limitation. In Stanziale ’771, first and second pulleys 145, 146, and interconnecting pivot 147 (all three of which Petitioner maps to claim 1’s “string guide[s]”) are pivotally connected to a number of intermediate members (e.g., lever arms or pushing arms 32, connecting elements 27, and constraining member 29) which are, in turn, pivotally connected to elastic members 10 (which Petitioner maps to claim 1’s “limb[s]”). See Pet. 41–42 (citing Ex. 1012 7:9–17, 8:26–8:13, 11:8–9, 14:18–15:22, 16:24–25, 16:29, 17:2, 17:15–17, 17:24–27, 19:12–30, 20:32–21:16, Figs. 1–7; Ex. 1016 ¶¶ 177–179); see also Ex. 1012 11:3–7, 11:34–12:4, 12:10–17, 16:29–18:3, 18:22–19:30, Figs. 8, 9, 10a, 10b. Therefore, Stanziale ’771, in Petitioner’s mapping, teaches the “string guide[s]” connected indirectly to the “limb[s].” Per the construction of the “mounted to” limitation employed herein (“connected to, either directly or indirectly”), Petitioner establishes, by a preponderance of the evidence, that Stanziale ’771 teaches the “string guide[s]” “mounted to” the “limb[s],” as recited in claim 1 of the ’015 patent. Contrary to Patent Owner’s concerns (see Paper 47, 1), the indirect connection between Stanziale ’771’s “string guide[s]” and “limb[s]” is not “unbounded.” Rather, the connection disclosed by Stanziale ’771 is the type of indirect connection supported by the intrinsic record. See supra § II.B. Patent Owner’s contention that “a POSA would be disinclined to rely on [Stanziale ’771] as a reference for the improved crossbow design disclosed in Claim 1” is not persuasive. See PO Resp. 38 (citing Ex. 2029 ¶ 46). The test for anticipation is whether a prior art reference discloses each and every element recited in the claim, not whether one of ordinary skill in the art would have been inclined to rely on the reference.

“In the present proceeding, Petitioner proposed — and Patent Owner does not dispute (see PO Resp. 3) — the following definition of a person of ordinary skill in the art: A hypothetical POSA to which the ’015 Patent pertains would be a technical person who has at least some experience working in the field of archery, reviewing crossbows or engineering related to bows and/or crossbows, and is generally familiar with prior art crossbows. (Ex. 1016 ¶17.) Such a person would likely have at least a bachelor’s degree in mechanical engineering or, alternatively, would have several years of experience in the field of archery or engineering related to bows and/or crossbows. (Id.) Pet. 28. As discussed above, we adopt Petitioner’s description of a person of ordinary skill for the purposes of this Decision. See supra § II.A. Petitioner alleges various deficiencies in Mr. Teater’s background, education, and knowledge. Paper 39, 4–8. Nevertheless, Mr. Teater satisfies the definition, of a person of ordinary skill in the art, that Petitioner advanced. Specifically, Mr. Teater has reviewed crossbows for 14 years, encompassing the relevant priority date for the ’015 patent, during which time he wrote evaluations of various bows and crossbows, developed and published testing standards for crossbows, and served on the Archery Trade Association’s technical committee for standards and guidelines. Paper 41, 4 (citing Ex. 2029 ¶¶ 3, 4, 7). Accordingly, Mr. Teater satisfies Petitioner’s definition of “a technical person who has at least some experience working in the field of archery, reviewing crossbows or engineering related to bows and/or crossbows, and is generally familiar with prior art crossbows.” Pet. 28. Petitioner emphasizes that Mr. Teater “does not have a degree in mechanical engineering.” Paper 39, 4 (citing Ex. 2034, 1; Ex. 1034, 43:20–44:5). However, no degree of any kind is mandatory for satisfying Petitioner’s definition of a person of ordinary skill in the art. Indeed, Petitioner’s definition states that “[s]uch a person would likely have at least a bachelor’s degree in mechanical engineering or, alternatively, would have several years of experience in the field of archery or engineering related to bows and/or crossbows.” Pet. 28 (emphasis added). There is no dispute that Mr. Teater meets this standard.
