“35 U.S.C. § 325(d) because Amarenco and Mann previously were presented to the Office during prosecution of the ’742 patent. See Prelim. Resp. 17–18. According to Patent Owner, Petitioner has identified additional references that “supposedly teach[] only some of what was missing—stimulation of a branch of the posterior tibial nerve but not to treat overactive bladder or incontinence.” Id. at 18. Patent Owner’s argument is flawed for two reasons. First, neither Svihra nor Ponsford were previously presented to the Office. Because Patent Owner does not argue that we should deny institution of Petitioner’s Svihra-based ground under § 325(d), and because that ground relies on a combination of art not previously presented, Patent Owner’s § 325(d) argument is unpersuasive. In that regard, we determine that even if we were to conclude the Amarenco-based ground warranted discretionary denial, the Svihra-based ground would not be subject to such denial and may alone justify institution. See USPTO, SAS Q&As (June 5, 2018) at D1.11 Additionally, for the Amarenco-based ground, Petitioner relies on a combination including prior art that was not previously presented, and Patent Owner does not show that additional prior art is cumulative to art presented during prosecution. We determine that Petitioner’s Amarenco-based ground 11 Available at: https://www.uspto.gov/sites/default/files/documents/ sas_qas_20180605.pdf is not substantially the same as one previously presented to the Office.

“priority benefit of the ’720 provisional application (at top center). See Ex. 1001, code (60) (listing “provisional application No. 5,995,873, filed on Oct. 2, 2006”). However, simply to claim the priority benefit of an earlier application is not necessarily to receive it. See In re NTP, Inc., 654 F.3d 1268, 1276 (Fed. Cir. 2011) (holding that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority.… Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120.”). As the diagram shows (and as we have verified), the ’529 application was a continuation-in-part of the preceding ’329 application. See Ex. 1001, code (63). However, the ’529 application was abandoned on February 10, 2016 (See Ex. 1052), and the succeeding application, U.S. Patent Application Ser. No. 15,474,875 (the “’875 application”) which is listed in the ’943 patent as being a continuation-in-part of the ’529 application, was not filed until March 30, 2017. See Ex. 1001, code (63) (stating that “said application No. 15/474,875 is a continuation-in-part of application No. 12/508,529”). Put simply, the ’875 application was not filed until over a year after the ’529 application was abandoned. As 35 U.S.C. § 120 states, in relevant part: An application for patent for an invention disclosed in the manner provided by section 112(a) (other than the requirement to disclose the best mode) in an application previously filed in the United States, or as provided by section 363 or 385, which names an inventor or joint inventor in the previously filed application shall have the same effect, as to such invention, as though filed on the date of the prior application, if filed before the patenting or abandonment of or termination of proceedings on the first application or on an application similarly entitled to the benefit of the filing date of the first application and if it contains or is amended to contain a specific reference to the earlier filed application. (emphasis added). In other words, if there is a “break in the chain” of priority caused by the abandonment or termination of an application claiming priority prior to filing of a subsequent application, the subsequent application loses the priority benefit of the abandoned or terminated application, as well as the priority benefit of all applications that antedate that abandoned or terminated application. Such is the case presently before us. Based on the current record, we are persuaded that the abandonment of the ’529 application prior to filing of the continuation-in-part ’875 application broke the priority chain leading to the ’720 provisional application, and the ’943 patent cannot, therefore, claim the priority benefit of the ’720 provisional application’s October 2, 2006 filing date. Consequently, the earliest date of which the ’943 patent could possibly claim the priority benefit is that of U.S. Patent Provisional Application Ser. No. 61/403,680 (the “’680 provisional application”) (located at the top of the left branch of the “family tree” depicted above), which has a filing date of September 20, 2010. See Ex. 1001, code (60). Burnett (i.e., the ’329 application) was filed on October 2, 2007 and thus antedates the ’680 provisional application. Consequently, Patent Owner’s argument fails based on the current record, and Burnett is prior art to the ’943 patent.” slip op. at 55

Ex. 2014 ¶ 87. On the contrary, far from being a “well-known, well-characterized, and discrete class” the prior art teaches a heterogeneous assembly of different classes of small molecule CRF1 receptor antagonists (Type I, Type II, and “atypical”) displaying a very considerable variety of structures, both in terms of the core pharmacophore (e.g., monocyclic, bicyclic, tricyclic, phenolic, cyclohexyl amide, etc.) as well as in the various side groups. Moreover, the challenged claims recite only “a CRF1 receptor antagonist or a pharmaceutically acceptable salt thereof,” the scope of which also encompasses the much larger (and, according to Williams) much more effective large-molecule (peptide) CRF1 receptor antagonists, about which the Specification is entirely silent.

This rule against giving effect to intended-use language in the preamble “reflects a longstanding substantive aspect of the patent statue—specifically, the ‘well settled’ fundamental principle ‘that the recitation of a new intended use for an old product does not make a claim to that old product patentable.’” Arctic Cat Inc. v.

In this case, we view the phrase “hand carriable,” as it appears in the preamble, to be indicative of an intended use of the claimed apparatuses, rather than a structural limitation, and as such, we do not see it to be limiting based on the current record. Patent Owner does not point to any particular structural limitation required by the preamble term “hand carriable.” See Prelim. Resp. 2–10. Although the independent claims each recite “a handle,” the claims do not explicitly tie this limitation to the “hand carriable” language in the preambles. In any case, to the extent the handle recited in the claims may be used for carrying the claimed apparatus, the claims need not rely on the preamble term “hand carriable” for antecedent basis, as the handle limitation is introduced in the body of the claims.

“On the current record, we find that the Petition provides sufficient rationale to modify Simpson in view of Liddell. See Pet. 57–61 (citing Ex. 1002 ¶¶ 250–267). For example, Petitioner contends that one of ordinary skill in the art would have been motivated to incorporate Liddell’s cyclonic separating apparatus into Simpson’s vacuum cleaner in order to reap “the benefits of cyclonic separation, including maintaining steady suction as the separator fills with dirt.” Id. at 59 (citing Ex. 1002 ¶¶ 256– 259). Petitioner explains that Organ establishes that “bagless vacuums like ‘cyclonic’ vacuums were ‘becoming increasingly popular’” in the prior art because they are able “to maintain a consistently high level of suction, even as the collecting chamber fills with dirt” (id. (citing Ex. 1006, 1:8–13)), and relying on the declaration testimony of Dr. Giachetti, argues that one of ordinary skill in the art would have “would have been motivated to substitute Simpson’s dust separation system with a bagless cyclonic separator for the same reason” (id.

Petitioner’s declarant asserts that a person of ordinary skill in the art would have had a bachelor’s degree in mechanical engineering or a similar field and 2-3 years of experience in machine design, including machines that include fluid dynamics or fluid paths, such as vacuum cleaners. Additional education could offset less experience and vice versa, and a POSA could have also obtained similar knowledge and experience through other means.

“Petitioner’s first reason why one of skill in art would combine Conrad335’s “cyclone separator” with IPVG’s stick or hand vacuum, is Conrad335’s explicit teaching that it is directed to “a ‘stick’ or ‘hand vacuum.’” Pet. 26 (quoting Ex. 1005 ¶ 376), 27–28, 29–30; Ex. 1002 ¶¶ 144, 149–153. Specifically, Conrad335 states that “the cyclonic embodiments described herein may be used in conjunction with . . . a stick vacuum cleaner, . . . a hand vacuum, . . . or any other type of vacuum cleaner.” Ex. 1005 ¶ 376. Conrad335’s explicit teaching provides a motivation to combine the teachings of Conrad335’s cyclonic embodiments with IPVG’s stick or hand vacuum. KSR Int’l, 550 U.S. at 418–419 (teaching in the art can show combination is obvious). Petitioner also argues that: A POSA would have understood that cyclonic filtration had certain advantages over dust-bag filtration, including (1) no bag needs to be replaced, reducing recurring costs; (2) unlike cyclonic cleaners, dustbag cleaners lose suction as they fill; and (3) cyclonic cleaners give the user a visual indication of how full the container is and when to empty. Pet. 30 (citing Ex. 1002 ¶¶ 150–53). This argument is supported by Petitioner’s declarant, and by citations to and a discussion of two prior art references, in addition to the teachings of Conrad335. Pet. 30–31 (citing Ex. 1002 ¶¶ 150–53; Ex. 1010, 1; Ex. 1016, 1:5–10; Ex. 1005 ¶¶ 2, 112.

“Advanced Bionics, 8. As explained above, during prosecution of the ’245 patent, the examiner issued a nonstatutory double patenting rejection because the claims were “not patentably distinct from” the ’742 patent claims.13 See supra Section I.H (citing Ex. 1010, 96). Petitioner argues that “[i]t was material error for the Examiner to both acknowledge that the ’245 claims were patentably indistinct from the ’742 claims and yet ignore the FWD and allow the claims despite the Board’s prior findings.” We find Petitioner’s argument persuasive. To determine whether Petitioner has sufficiently shown material error, we look at, for example, “the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection.” Advanced Bionics, 9 (citing Becton, Dickinson & Co. v.

“We agree with Patent Owner. Claim terms need only be construed to the extent necessary to resolve the controversy. Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011). On this record and for purposes of this Decision, we see no need to expressly construe any claim term. Patent Owner appears to suggest, although it does not explicitly argue, that the claims require “a single drop of [0].025% brimonidine.” See Prelim. Resp. 6; see also id. at 27 (arguing Gil is “with multi-dosed 0.03% brimonidine”); id. at 28 (arguing Dean is with “multi-dosed concentrations”). To the extent our understanding is correct, Patent Owner should expressly discuss at trial any construction that would so limit the claim. Such discussion should be set forth in a separate section of a response, if filed, designated for claim construction; claim construction positions should not be merely included in arguments over the merits on patentability.” slip op. at 24

“However, we prefer Patent Owner’s definition of the required 2–3 years of experience in “the development and syntheses of nucleosides, nucleotides, and nucleic acids, including, but not limited to, the syntheses of oligonucleotides through solid phase oligonucleotide synthesis (‘SPOS’)” to Petitioner’s more generalized requirement of having experience in “medicinal chemistry, synthetic organic chemistry, and nucleic acid chemistry, including the development of oligonucleotide therapeutics, diagnostics, or building blocks.” Both parties acknowledge that the level of skill in the art is very high. See, e.g., Resp. 17; Reply 2. We find that, to achieve a level of ordinary skill in the art, a person with the requisite educational background would require 2–3 years of experience for one possessing a doctorate in the relevant field, or 3–5 years for one with a lesser degree (to compensate for the additional educational experience gained by achieving a doctorate) in the specific techniques recited by Patent Owner. We reject the terminal clause “pursuant to P(III) chemistry” proposed by Patent Owner as redundant in that a person engaged for a number of years in “the development and syntheses of nucleosides, nucleotides, and nucleic acids” including SPOS, would likely have an operant knowledge of P(III) chemistry. Consequently we adopt the following definition of a person of ordinary skill in the art: “A person of ordinary skill in the art having a Ph.D. (or equivalent degree) in organic or medicinal chemistry, and 2 to 3 years of post-graduate work experience in the development and syntheses of nucleosides, nucleotides, and nucleic acids, including, but not limited to, the syntheses of oligonucleotides through solid phase oligonucleotide synthesis (‘SPOS’)” and, alternatively, “a person of ordinary skill in the art would have a Bachelor’s or Master’s degree in organic or medicinal chemistry who had at least 5 years of extensive work experience in these fields.”” slip op. at 12

“As for Dr. Baran, we are not persuaded by Patent Owner’s argument that Dr. Baran is not sufficiently experienced or qualified to opine with respect to the claimed subject matter. A review of Dr. Baran’s extensive curriculum vitae (Ex. 1003, 79–137), indicates that he is deeply experienced and extensively published in the field of oligonucleotide synthesis. Patent Owner’s argument that Dr. Baran is principally experienced in P(V) techniques presupposes that experience in that technique indicates an ignorance of P(III) methodologies. We do not find this position consistent with the breadth of Dr. Baran’s C.V. We will weigh Dr. Baran’s testimony, and that of Dr. Hrdlicka, against the cumulative weight of the evidence of record in this inter partes review in assessing the credibility and probative value of their respective testimonies.” slip op. at 13

“Furthermore, both Petitioner and Patent Owner agree that clear errors exist in the wording of challenged claims 3–5. Both parties agree that a person of ordinary skill in the art would have recognized that the limitation reciting “where M is selected from the group consisting of succinyl, oxalyl, and hydroquinolynyl” should properly read “where M is selected from the group consisting of ethyl, oxalyl, and hydroquinolynyl.” Pet. 18–20; PO Resp. 15. Both parties further agree that the language of claim 5 mistakenly omits the italicized portions of the limitation reciting “NH is capable of being attached to a solid support with a spacer selected from the group consisting of C1–C20 alkyl, ethyloxyglycol, and a combination of alkyl and ethyleneglycoxy,” as is expressly recited in claims 3 and 4. Pet. 21–22 (citing Ex. 1003 ¶ 158); PO Resp. 15. We agree with both parties’ reasoning with respect to these errors, and we construe the claims as reciting the corrected language, such that claims 3–5 read, in relevant part “where M is selected from the group consisting of ethyl, oxalyl, and hydroquinolynyl” and claim 5 additionally reads “NH is capable of being attached to a solid support with a spacer selected from the group consisting of C1–C20 alkyl, ethyloxyglycol, and a combination of alkyl and ethyleneglycoxy.” See Fitbit, Inc. v.
