- Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner
“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).

See generally, Ex. 1007. Accordingly, we find Dr. Patterson qualified to opine on the level of ordinary skill with regard to issues of drug design, evaluation of effectiveness, and drug administration, but we find he is not adequately qualified to opine on the level of ordinary skill with regard to issues of treating hair loss disorders.” slip op. at 7

“Patent Owner proposes the same definition as Petitioner, but adds that the skilled artisan “would also have had experience in JAK inhibition, deuteration, and AA [alopecia areata] formulations, or access to a person with that knowledge and experience.” Resp. 15 (citing Ex. 2059 ¶ 14). Patent Owner’s expert Dr. Ko critiques Petitioner’s proposed definition as “incomplete, because it lacks any requirement for experience, or access to individuals with experience, in JAK inhibition, deuteration, and AA formulations.” Ex. 2059 ¶ 16. However, neither Dr. Ko nor Patent Owner explains what difference this additional direct experience would have provided to an artisan with the skill level proposed by Petitioner, particularly when Petitioner’s definition includes “experience in treating hair loss disorders,” and for which the record contains evidence that existing JAK inhibitors such as ruxolitinib had been identified as causing reversal of hair loss caused by AA. Ex. 1003, 1043. Accordingly, we adopt Petitioner’s proposed definition as consistent with the level of skill apparent in the cited prior art. In any event, as Patent Owner does not explain why its alternative definition would have any bearing on the outcome of the present case, and as we discern no appreciable difference in the parties’ definitions, we note our findings and conclusions would be the same regardless of which definition were adopted. We further note that the prior art itself demonstrates the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding 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.

“C. Claim Construction We construe claims 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. Therefore, we construe the challenged claims under the framework set forth in Phillips v. AWH Corp., 415 F.3d 1303, 1312–19 (Fed. Cir. 2005) (en banc). Under this framework, claim terms are given their ordinary and customary meaning, as would have been understood by a person of ordinary skill in the art (“POSA”), at the time of the invention, in light of the language of the claims, the specification, and the prosecution history of record. Id. Only those terms that are in controversy need be construed and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co.

“Petitioner proposes claim constructions for the terms “substantially below” and “substantially inwardly” recited in claims 1 and 6. Pet. 40–41. In the Decision on Institution, we determined that it was not necessary to construe the terms at that stage of the proceeding. Dec. Inst. 9–10 (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017)). Patent Owner contends “the claim terms ‘substantially below’ and ‘substantially inwardly’ are sufficiently clear on their face to preclude any need for claim construction,” but proposes claim constructions that differ somewhat from Petitioner’s proposed constructions in the event the Board determines that these terms require claim construction. PO Resp. 13, 15–16. Patent Owner also proposes a claim construction for the term “upper tubular periphery” recited in claims 1 and 6 that Petitioner opposes. Id. at 17–19; Pet. Reply 7–10. Only terms that are in controversy need to be construed, and then only to the extent necessary to resolve the controversy. Nidec, 868 F.3d at 1017.

“We agree with Patent Owner that Metzger’s gaps define fluid passages located between adjacent side support beams 25 (i.e., “internal walls”) and are not formed in any of the side support beams. We are not directed to any written description in Metzger indicating that the gaps are formed in a side support beam.7 Instead, Figures 5 and 6 of Metzger depict the gaps as being defined between four distinct side support beams 25. Furthermore, as Patent Owner points out, Mr. Kuchel appears to agree that there are no passages formed through the side support beams 25 of Figures 5 and 6. Ex. 2003, 107:12–108:9, 108:17–108:21. For these reasons, we determine that Metzger’s gaps are not formed through an internal wall, as required by claim 1. In the Reply, Petitioner asserts that, even if Metzger discloses four discrete, spaced-apart beams or walls, “the gaps or slices between walls are apertures in a structure through which air can pass.” Pet. Reply 15 (emphasis added). This argument is not persuasive because claim 1 recites that the fluid passage is formed through the internal wall (which Petitioner asserts is met by Metzger’s side support beam 25), not just any structure. Petitioner’s general assertion that air passes through “a structure” fails to establish that the gaps are formed in a side support beam.” slip op. at 16

“Specifically, Petitioner argues that one of ordinary skill in the art would have understood from Metzger “that an air passage would be necessary to bypass the side support beam 25 and inflate the upper tubular periphery for the air mattress to function as intended.” Id. (citing Ex. 1002 ¶ 200). According to Petitioner, because Metzger discloses only a single air inlet valve, an ordinarily skilled artisan would have understood that providing openings, or fluid passages, through the side support beam 25, in lieu of or in addition to the gaps between the side support beam 25, would have been a simple solution to adequately inflate the peripheral frame of the mattress defined by the side support beam(s) 25. Id. at 74–75 (citing Ex. 1002 ¶ 200). Petitioner thus presents two alternate theories for modifying Metzger: (1) providing fluid passages in at least one side support beam 25 in addition to the gaps, and (2) providing fluid passages in lieu of the gaps. In support of the first theory, Petitioner only argues that providing fluid passages in the side support beams, in addition to the gaps between the ends of the side support beams, would have allowed the peripheral frame to inflate more freely. Id. at 75 (citing Ex. 1002 ¶ 201). In its Response, Patent Owner contends that “Petitioner is just wrong.” PO Resp. 45 (citing Ex. 2001 ¶¶ 146–149). Dr. Letton testifies that pumps used to inflate air mattresses are low flow and low pressure and generally inflate an air mattress to a maximum pressure of around 1 psi. Ex. 2001 ¶ 147.

“Factual indicators of the level of ordinary skill in the art include “the various prior art approaches employed, the types of problems encountered in the art, the rapidity with which innovations are made, the sophistication of the technology involved, and the educational background of those actively working in the field.” Jacobson Bros., Inc. v.

“direct attachment” of the flexible valve element to the frame. Id. at 8. However, the portion of the Specification on which Patent Owner relies also describes indirectly attaching the flexible valve element to a frame by securing it to a band that is directly attached to the frame. Ex. 1001, 7:55–66. This type of indirect attachment is illustrated in Figure 3, reproduced below right. The Specification describes Figure 3 as follows: As illustrated in FIG. 3, the flexible valve element 22 is attached to the central portion 36 of the frame 20 at a position substantially centered between the anchors 34. Although the valve element 22 may be attached to the frame 20 by other means without departing from the scope of the present invention, the valve element of the preferred embodiment is attached to the frame by adhesive bonding. Further, the flexible valve element 22 is attached to the frame 20, and more particularly to the band 40, at several attachment points 56 around the frame. Id. at 7:57–66 (emphasis added). This passage indicates that the flexible valve element is attached to the frame in two ways: (1) directly by being bonded to the central portion 36 of frame 20 and (2) indirectly by being attached to band 40 at attachment points 56. The Specification later expresses a preference for bonding valve element 22 to band 40 with adhesive. Id. at 8:11–14. Interpreting “attached to” to mean “directly attached to” as suggested by Patent Owner would be inconsistent with the Specification’s broader description of how valve element 22 is attached to frame 20. We interpret claim language “in light of the specification of the patent in which it appears.” 37 C.F.R. § 42.100(b) (2018). Doing so requires us to interpret claim language in a manner that “corresponds with what and how the inventor describes his invention in the specification.” In re Smith Int’l, Inc., 871 F.3d 1375, 1383 (Fed. Cir. 2017). The inventor describes both direct and indirect methods of attaching the flexible valve element to the frame. Accordingly, we interpret “attached to” as encompassing both direct and indirect ways of attaching the flexible valve element to the frame.” slip op. at 12

“Petitioner’s argument that Bessler’s valve is attached to the central part of the frame of claims 1 and 31 fails. Bessler’s valve is undeniably attached to its frame because the cuff portion of the valve is sutured to its stent. Claims 1 and 31 require the valve element to be attached to a portion of the frame located along the radial centerline. Ex. 1001, 19:19–20 (claim 1), 22:67–23:2 (claim 31). Bessler’s valves fail to meet this requirement. Bessler’s stent 32 is a hollow cylinder devoid of structure located along its centerline,3 and the “central portion of the frame” identified by Petitioner, straight sections 33, is part of walls 31 located on the radial periphery of stent 32. Id. at 5:28–43, Figure 4. Regardless of how Bessler’s valve is attached to the wall of its stent, the valve is not attached to structure “located along a centerline” as recited in claims 1 and 31. Therefore, we determine that Petitioner fails to establish by a preponderance of evidence that Bessler anticipates claims 1 and 31 or their respective dependent claims 2, 3, 8, 9, 32–35, and 37.” slip op. at 19

“For all these reasons, Dr. Chronos’s assertion that incorporating Johnson’s strut-based frame and membrane into Bessler’s stent would render the combined structure too large is not supported by the objective evidence of record.

Instead, we determine that Petitioner has proven that an ordinarily skilled artisan would 5 Ex. 1009, 1:12–13. have been motivated to combine the teachings of Bessler and Johnson as alleged.” slip op. at 38
