“First, Patent Owner has not shown possession of the disputed feature of a “radio communication module [that] is configured to utilize a secure identifier, the secure identifier comprising a specified excitation.” In the ’406 application, the term “excitation” is used exclusively to refer to a light beam signal. See Ex. 2015, 7:8–13, 9:8–10, 23:9.2 The ’406 application discloses that an identification box on an aircraft may include both an RF module and a separate light sensor. See Ex. 2015, 7:3–11. But nowhere does the ’406 application describe receiving a light beam (e.g., an excitation) with the RF module of the identification box (as opposed to the light sensor), so as to provide support for proposed substitute claim 22’s recitation of a “radio communication module” configured to utilize “a secure identifier . . . comprising a specified excitation.” We disagree with Patent Owner that it suffices that one of ordinary skill in the art “would recognize that these disclosures are equally applicable to the RF-only embodiments” (Reply 5). “It is not sufficient for purposes of the written description requirement . . . that the disclosure, when combined with the knowledge in the art, would lead one to speculate as to modifications that the inventor might have envisioned, but failed to disclose.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997). On this record, and having reviewed the ’959 Patent, the ’153 provisional, and the ’406 application, we find no evidence in those documents that the named inventor was in possession of the concept of a radio communications module “configured to utilize a secure identifier” where “the secure identifier compris[es] a specified excitation.” Second, setting aside the “radio communication module” in proposed substitute claim 22, Patent Owner also has not shown that the named inventor was in possession of the feature of a “secure identifier comprising a specified excitation.” Patent Owner’s argument that the ’406 application describes a light beam directed to a particular aircraft (see Reply 4–5) is 2 The same is true of the ’153 provisional. See Ex. 2016 ¶¶ 29, 34. unavailing. The fact that the properties of a particular light beam indicate that the light beam is intended for a particular aircraft does not demonstrate that the light beam is a “secure identifier,” as we have construed that term. Patent Owner has not identified any disclosure in the ’406 application of a “secure identifier” comprising a light beam, let alone that such light beam can be utilized by a “radio communication module.” The only references to “secure” identifiers in the ’406 application describe radio frequency signals. See Ex. 2015, 2:4–6, 15:21–17:12.3 Having reviewed the ’959 Patent, the ’153 provisional, and the ’406 application, we find no evidence in those documents that the named inventor was in possession of the concept of a “secure identifier comprising a specified excitation.”” slip op. at 15
- ScopeDecided for patent owner
“not impermissibly broaden the scope of the claims of the ’959 Patent. As Patent Owner suggests, there were no limitations in original claim 21 on the type of radio signal the radio communication module could receive, and so it follows that proposed substitute claim 22 does not now encompass receiving a broader set of radio signals. We see no basis for Petitioner’s argument that the past tense verb “received” limited original claim 21 to “signals of a compatible ‘type’ and ‘range.’” Opp. 7. Moreover, the claim language (with the proposed deletion shown double brackets) provides that “the radio communication module is configured to receive a [[received]] radio signal.” Any radio signal that the radio communications module receives would necessarily be a “received” radio signal. Thus, deleting the redundant word “received” does not enlarge the scope of this claim limitation. We also are not persuaded by Petitioner’s suggestion that removing the term “received” broadens original claim 21 by deleting a requirement that the radio signal have already been previously received by the claimed device. See Sur-reply 9. Original claim 21 simply recited, using redundant language, that “the radio communication module is configured to receive a received radio signal.” Ex. 1001, 18:5–7. The most natural reading of this language is that the phrase “received radio signal” is just a description of a radio signal that is received by the recited radio communications module. Petitioner has cited no persuasive evidence that one of ordinary skill in the art would have counterintuitively interpreted this language to impose an additional requirement that the “received radio signal” must have been received twice—a first time by some other component of the device, and a second time by the recited radio communication module. Accordingly, we determine that the proposed amendment does not improperly broaden claim scope.” slip op. at 10

“572 U.S. 898 (2014). See Memorandum: Approach to Indefiniteness Under 35 U.S.C. § 112 in AIA Post-Grant Proceedings (Jan. 6, 2021).4 Under Nautilus, a claim is indefinite if fails to “inform those skilled in the art about the scope of the invention with reasonable certainty.” 572 U.S. at 910. We agree with Patent Owner that neither of the identified terms are indefinite. Regarding the term “low-altitude aircraft,” we determine the Specification provides a sufficient basis for understanding the scope and meaning of this term with reasonable certainty. The U.S. Court of Appeals for Federal Circuit has explained that, when a term of degree is recited in a claim, it is necessary “to determine whether the patent’s specification provides some standard for measuring that degree.” See Seattle Box Co. v. Indus. Crating & Packing, Inc., 731 F.2d 818, 826 (Fed. Cir. 1984); see also Datamize, LLC v. Plumtree Software, Inc., 417 F.3d 1342, 1350 (Fed. Cir. 2005) (“Some objective standard must be provided in order to allow the public to determine the scope of the claimed invention.”). Here, the Specification describes the related art as including “small UASs (e.g., aircrafts up to 25 pounds flying up to 500 ft of the low altitude airspace).” Ex. 1001, 1:50–52. One of ordinary skill in the art would understand from the Specification that the cited disclosure provides an objective standard for determining the scope of a low-altitude aircraft as one that is designed to fly up to a maximum altitude of about 500 feet.” slip op. at 20

“[c]ombin[e] the tapered region of Piepho with the shaft of Torrence, the tapered region would extend from an uppermost extremity of the shaft.” RMTA Opp. 9. But, Petitioner concedes that neither reference discloses a tapered region extending from the uppermost extremity. Petitioner argues that Torrence’s shaft is straight (Amended RMTA Sur-reply 9) and that “[t]he tapered region of Piepho does not extend to the extreme end of the shaft.” RMTA Opp. 11 (emphasis added). Because neither Torrence nor Piepho discloses a shaft with a tapered region that “extends from an uppermost extremity of the shaft,” we find that the combination of Torrence and Piepho does not teach limitation 11[a]. We now analyze whether Petitioner provides reasoning with a rational underpinning why a person of ordinary skill in the art would have been motivated to modify Torrence with Piepho to extend Torrence’s taper from the upper extremity of its shaft. slip op. at 22

“onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed.

This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A patent claim is unpatentable under 35 U.S.C. § 103(a) when the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) when in evidence, objective evidence of nonobviousness, i.e., secondary considerations.4 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). Additionally, the obviousness inquiry typically requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed.

Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’302 patent, the background technical field, the prior art, and Petitioner’s proposed and unopposed definition of the skilled artisan, we apply the level of skill set forth above, which is consistent with the testimony of Dr. Buehrer (Ex. 1003 ¶ 23), except that we omit the two instances of “at least” to remove the unbounded nature of the definition.” slip op. at 13

“In contrast, Patent Owner’s declarant, Mr. Williams, testifies based on his “experience[,] that tenons are generally included in the larger portion of two table top portions.” Ex. 2006 ¶ 55. However, Mr. Williams’ experience does not explain why an ordinary observer would understand such functional and ornamental characteristics of tenon and hole arrangements. Id. Nor does this testimony proclaim that tenons must be in the larger of two table top potions. Indeed, even considering an ordinary observer imbued with Mr. Williams’ level of expertise and experience, and understanding for instance that it may be more likely that the wider portion includes tenons, this does not resolve the glaring inconsistency that Figure 1 illustrates holes and Figure 8 illustrates tenons. In other words, Mr. Williams’ “experience” does not resolve the visible tension that, on one hand, Figure 1 illustrates holes as part of the claimed ornamental design in the wider portion of the table top, and on the other hand, Figure 8 illustrates tenons as part of the same wider portion of the table top. The problem here may be more eloquently explained as “Two roads diverged in a yellow wood[,] And sorry I could not travel both.” Robert Frost, The Road Not Taken, The Poetry of Robert Frost—The Collected Poems, 105, Henry Holt and Co. (1969). Considering the entire record before us in this case we credit Mr. Hatch’s testimony. The issue is not, as Patent Owner has framed it, whether “[o]ne of ordinary skill in the art would understand how the tenons and holes should be positioned on each of the table top portions.” Reply Opp. 7. The question is whether a person of ordinary skill in the art viewing the design for a table top in the proposed substitute claim as would an ordinary observer, understand whether or not the wider portion of the table top as Figures 1 and 6, holes. As Mr. Hatch persuasively explains, in the proposed substitute claim a majority of the drawings for the wider portion, i.e., Figures 1–6, omit the tenons added in Figure 8. Ex. 1011 ¶ 37 (Mr. Hatch testifying that “Figure 8 is the only amended figure that adds tenons/dowels.”) Indeed, Figures 1 and 6 not only fail to illustrate tenons, but actually are amended to include holes rather than tenons, as described in the Motion to Amend. See, e.g., Motion to Amend 6 (Patent Owner describing, “Figure 1: Removal of disclaimer of a total of four holes by amending the outline of the four holes from broken lines to solid lines.”).

“On the complete record in this proceeding, we determine that a designer of skill in the art considering the claim from either their own, or the perspective of an ordinary observer, would be uncertain whether the wider portion of the claimed table top depicted in Figures 1–8 includes tenons, or holes. It is reasonable that anyone observing two distinct ornamental designs for the same wider portion of the table top would be unclear as to the claimed ornamental design where holes are shown in one figure but tenons are shown in another figure illustrating the same wider portion of the table top. Observing as a whole, the figures illustrating the table top in the proposed substitute claim, the question remains, does the wider portion of the table top include tenons, or holes? See Maatita, 900 F.3d at 1376 (“Ultimately, a patent is indefinite for § 112 purposes whenever its claim, read in light of the visual disclosure (whether it be a single drawing or multiple drawings), ‘fail[s] to inform, with reasonable certainty, those skilled in the art about the scope of the invention.’”) (quoting Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898 (2014)). proposed substitute claim fails to “inform those skilled in the art about the scope of the invention with reasonable certainty.” See Nautilus, 572 U.S. at 910. Thus, Petitioner has shown, by a preponderance of the evidence, that the proposed substitute claim is indefinite and we accordingly deny Patent Owner’s Noncontingent Motion to Amend.” slip op. at 29
- Disclosure Requirements (§112) › Definiteness (Nautilus)IndefiniteUnpatentable
“Federal Circuit recently explained that “a design patent is indefinite under § 112 if one skilled in the art, viewing the design as would an ordinary observer, would not understand the scope of the design with reasonable certainty based on the claim and visual disclosure.” In re Maatita, 900 F.3d 1369, 1377 (Fed. Cir. 2018). In Maatita, the Federal Circuit reversed the Board’s finding of indefiniteness of a design for a shoe bottom, i.e., a shoe sole, finding that Maatita’s two-dimensional drawing clearly demonstrates the perspective from which the shoe bottom should be viewed. A potential infringer is not left in doubt as to how to determine infringement. In this case, Maatita’s decision not to disclose all possible depth choices would not preclude an ordinary observer from understanding the claimed design, since the design is capable of being understood from the two-dimensional, plan- or planar-view perspective [] shown in the drawing. Id. at F.3d 1378–79. Different from Maatita, the issue in this proceeding is not whether an ordinary observer would sufficiently understand a three-dimensional ornamental design from a two-dimensional figure, but whether inconsistencies between figures of the proposed substitute claim render the scope of the claimed table top uncertain. See Maatita, 900 F.3d at 1376 (The Federal Circuit specifically distinguishing Maatita’s single two-dimensional drawing from indefiniteness issues raised by inconsistent drawings: “[h]ere, we are not dealing with inconsistencies in the drawings, or inconsistencies between the drawings and the verbal description, but” slip op. at 24

“evidence. The challenged claims require that a sacrificial anode be placed within a certain distance—10 inches—of the hot liquid inlet, and, because the inlet has some non-zero size, it might be possible for an anode to be within that distance from some parts, but not from all parts, of the inlet. Accordingly, specifying the center axis of the inlet as the point from which to measure the distance to the anode improves on the plain words of the claim in terms of achieving the claim’s objective of placing the anode within a specified distance of the inlet. Moreover, when discussing the distance from the inlet to the anode, the specification of the ’494 patent uses the language “within 10 inches in any direction of the center axis of the inlet connection.” Ex. 1001, 7:61–64. Thus, the intrinsic evidence supports adopting Petitioner’s claim construction. Petitioner’s declarant, Dr. Medlin, relies on Petitioner’s proposed construction. See, e.g., Ex. 1004 ¶¶ 20 (noting that the construction “within 10 inches of the center axis of [a] hot liquid inlet” “ha[s] been adopted by Petitioner”), 96 (“the sacrificial anodes contained in each of the turbulators 2 would be placed within 10 inches of a center axis of a hot liquid inlet to the radiator of Tomosada”), 144 (“A POSITA would understand from Figure 1 that the sacrificial anode 14 is within 10 inches of a center axis of a hot liquid inlet”), 267 (“These teachings would further motivate a POSITA to located the sacrificial anode 12 within 10 inches of a center axis of the hot liquid inlet.”). This support for Petitioner’s proposed construction provides further reason for us to adopt it. Because it is supported by the intrinsic evidence of record, because Patent Owner proposes no alternative construction, and because Petitioner’s expert supports it, we adopt the construction of “within 10 inches of a hot liquid inlet to the radiator” that Petitioner proposes. Thus, we construe this term as “within 10 inches of the center axis of a hot liquid inlet to the radiator.” In other words, when discussing the distance between a hot liquid inlet and a sacrificial anode, we interpret “hot liquid inlet” as “center axis of the hot liquid inlet.”” slip op. at 5

“Inherency may be relied upon in arguing either anticipation or obviousness. Schering, 339 F.3d at 1377 (applying inherency in an anticipation context); Par Pharma. Inc. v. TWI Pharma., Inc., 773 F.3d 1186, 1195–96 (Fed. Cir. 2014) (applying inherency in an obviousness context). In both cases, however, “[t]he mere fact that a certain thing may result from a given set of circumstances is not sufficient.” Therasense, Inc. v. Becton, Dickinson & Co., 593 F.3d 1325, 1332 (Fed. Cir. 2010). Instead, “the limitation at issue necessarily must be present, or the natural result of the combination of elements expressly disclosed by the prior art.” Par Pharma., 773 F.3d at 1195–96. Here, Petitioner has not shown sufficiently that, in Godefroy, the sacrificial anode necessarily is placed within 10 inches of the center axis of the hot liquid inlet. Dr. Medlin testifies that Figure 1 of Godefroy shows that “an entirety . . . or at least a significant portion of the sacrificial anode 14, is within 10 inches of a center axis of the inlet.” Ex. 1004 ¶ 144. But we cannot say that Figure 1 of Godefroy is clear on its face, or reasonably suggests, that this is necessarily the case. There are no dimensions shown on Figure 1, so it is unclear from the figure what the diameter of pipe 12 is. If that diameter is larger than 20 inches, then it simply is untrue that “sacrificial anode 14 is . . . necessarily placed within 10 inches of a center axis of a hot liquid inlet to the radiator,” as Dr. Medlin testifies. Id. ¶ 361. As noted above, neither Petitioner nor Dr. Medlin relies on the hot liquid inlet of Godefroy having any particular diameter, and Godefroy is silent as to the diameter of its inlet. Pet. 69–70; Ex. 1004 ¶¶ 144, 359–361, 381–382, 406–408; Ex. 1008, 1–15. Moreover, as Patent Owner notes, there is a wide range of sizes of radiators, including automobile radiators, available. Prelim. Resp. 3–5; Exs. 2001–2003. In the absence of any testimony or other evidence that tends to show that radiator inlet pipes necessarily have diameters less than 20 inches, Petitioner has not shown sufficiently that the diameter of Godefroy’s inlet pipe is small enough to ensure that any portion of the anode necessarily is within 10 inches of the center axis of the inlet.” slip op. at 11
