“The question before us, therefore, is whether the Petitioner’s proffered explanation that it has proposed a different claim interpretation before the Board because the District Court may decline to adopt the narrower claim interpretations it advocates there is sufficient. We find that Petitioner’s explanation is sufficient because it follows the Director’s exemplary logic. Whether a district court has already or might in the future decline to adopt constructions that a petitioner proposes in related district court litigation merely reflects the timing of when a dispute over claim interpretation will be resolved. The Director and Patent Owner both recognize that, to resolve the dispute over claim interpretation that exists here, a decision-maker must determine “a single claim construction that best captures the true meaning of the patent claim.” Remand 4; PO Remand Br. 3.

“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.

“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.

“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.

“For the reasons discussed below, on the full trial record, we find that Patent Owner has not carried its burden of showing by a preponderance of the evidence that the proposed substitute claims introduce no new matter relative to the original disclosure. 35 U.S.C. § 326(d)(3); 37 C.F.R. § 42.221(d)(1); see also Paper 58, 2 (Patent Owner acknowledging that it “bears the burden to meet the regulatory and statutory requirements” for a motion to amend, including demonstrating that the substitute claims do not “introduce new matter”).

“Petitioner persuades us that the ’418 Application lacks adequate written description support for the formulation limitations of proposed substitute claim 18 [limitations 18a–8c]. As outlined by Petitioner and its declarants, the ’418 Application, including the Abstract, Field of the Invention, Summary of the Invention, and Detailed Description of the Invention sections, uniformly focuses on phosphate prodrugs of levodopa and carbidopa. See, e.g., Ex. 1004 (Sloan Decl.) ¶¶ 38–55, 64–69; Ex. 1003 (LeWitt Decl.) ¶¶ 89–97; Ex. 1047 (Forrest Decl.) ¶¶ 40–74, 80–92; Opp. 6– 10; Pet. 23–26, 49–55. We agree with Petitioner that “nothing in the specification suggests that the invention includes methods of subcutaneous infusion with anything other than the carbidopa prodrugs and L-dopa prodrugs of Formulas (I) and (II), respectively, or teaches how to get sufficient amounts of either L-dopa or carbidopa into solution, or achieve particular L-dopa plasma levels, without those particular prodrugs.” Pet. 27. Petitioner persuades us that the ’418 Application fails to contain “[so] much as a single generic sentence, anywhere in the application, suggesting the inventors possessed the claimed formulations.” Sur-reply 3. Additionally, the ’418 Application contains no example teaching administration of an aqueous formulation comprising carbidopa itself with levodopa itself or one of the three claimed levodopa prodrugs, let alone one that is suitable for continuous subcutaneous administration. See Ex. 1047 (Forrest Decl.) ¶¶ 61–72, 82–92. Patent Owner is correct that to establish written description support, neither “an actual reduction to practice,” nor a verbatim recitation of the claims is required. Sur-reply 4. Nevertheless, “[a]lthough examples are not always required to satisfy the written description requirement, the lack of any disclosure of examples may be considered when determining whether the claimed invention is adequately described.” Bos.

Here, the lack of an actual reduction to practice or verbatim description of a formulation that falls within the scope of the claims is relevant, because we also see no other description or material in the ’418 Application that suggests the claimed methods extend to continuous subcutaneous administration of a composition comprising levodopa or one of the three claimed levodopa prodrugs, together with carbidopa, in an aqueous carrier.” slip op. at 28

“On the other hand, Petitioner shows that Patent Owner took positions in its Motion to Amend that it only later sought to support with technical declarations.

Patent Owner, however, “chose to forgo any expert support” on these issues at the time it filed its Motion to Amend, and instead waited until the Reply to submit technical declarations in support of these arguments. Id. We agree with Petitioner that although Patent Owner “was not required to anticipate the arguments that [Petitioner] would make in its Opposition” to the Motion to Amend, if Patent Owner “wanted to provide expert testimony to support the positions it actually took” in that Motion, “the TPG required [Patent Owner] to do so at that time, instead of waiting until [Petitioner] had limited ability to respond.” Id. at 5. Accordingly, we agree with Petitioner that in this respect at least some portions of Patent Owner’s Declarations are untimely, because it is “improper for a reply to present new evidence (including new expert testimony) that could have been presented in a prior filing.” TPG 74. Nevertheless, an order striking arguments and evidence in their entirety is an “exceptional remedy,” particularly under the circumstances here, where some portions of the Declarations are proper, while other portions are untimely.

Under the facts of this case, Patent Owner was permitted to file evidence to respond to Petitioner’s unpatentability claims, but also belatedly supported positions it made in earlier attorney argument. Petitioner’s Motion to Strike, however, challenges all of Patent Owner’s evidence, without acknowledging that some portions constitute proper reply. Although “[t]he Board is not required to attempt to sort proper from improper portions of the reply” (TPG 74, emphasis added), under the circumstances here, we agree with Patent Owner that Petitioner’s lack of specificity as to what it seeks to strike is fatal to Petitioner’s motion.

“We find the testimony of Dr. Atlas on the key point of obviousness of pre-mixing processing to be less persuasive than that of Mr. Brown. We also find Dr. Atlas’ testimony falls short of adequately explaining how the combination of Cohen and Martin teaches a nexus (i.e., the “based on both the first [shaped] output signal and the second [shaped] output signal” (emphasis added) (hereinafter, “based on both limitation”) limitation recited in claim 1) between the claim 1 requirements of: (1) a condition precedent of shaping both a first output signal and a second output signal; and (2) a subsequent result of using both the first shaped output signal and the second shaped output signal if the hearing aid is in a third mode. Dr. Atlas assumes that one of ordinary skill in the art would process separately each signal and then mix them. Ex. 1003 ¶ 66. We find Dr. Atlas’ assumption is flawed. Specifically, in making this assumption, Dr. Atlas does not address adequately how the combination of Cohen and Martin opines “it would have been obvious to a person of ordinary skill in the art” (emphasis added), his later sentences appears to base his opinion principally on the reason one of ordinary skill in the art could do it. Id. In particular, he testifies: Because Cohen’s hearing aid applies different hearing aid profiles to different input sources, it would have been obvious to a person of ordinary skill in the relevant art to add the functionality of the combination mode as taught by Martin to Cohen’s hearing aid such that the speaker would produce an audible sound based on the output signals of the processor. Combining two signals such that both signals are sent to a speaker to an audible combination of sounds, that is where each signal is sufficiently perceived, was well within the technical ability of a person of ordinary skill in the art. To accomplish this would require that each one of the two signals is passed through an appropriate hearing aid profile. For example, it would have been obvious to a person of ordinary skill in the art that a different hearing aid profiles could be used for an audio coil inputs and that of a neighboring conversation and environmental sounds through a microphone. Namely, it is commonly known that the different frequency sensitivity of an audio telecoil versus a microphone can be beneficially compensated for. (Rodriquez, Ex. 1011, Abstract)” slip op. at 24
