WALLACH, Circuit Judge.
Appellee E.I. DuPont de Nemours & Co. (“DuPont”) sought inter partes reexamination of various claims of Appellant Monsanto Technology LLC’s (“Monsanto”) U.S. Patent No. 7,790,953 (“the ’953 patent”). The U.S. Patent and Trademark Office’s (“USPTO”) Patent Trial and Appeal Board (“PTAB”) issued a final decision that affirmed an examiner’s rejection of claims 1, 7, 12-22, 24, and 27-30 (“the Asserted Claims”) as anticipated by U.S. Patent No. 6,426,448 (“Booth”), and of, inter alia, claim 2 as obvious over Booth. See E.I. DuPont de Nemours & Co. v. Monsanto Tech. LLC, No. 2015-007692, 2016 WL 4255131, at *3 (P.T.A.B. Aug. 10, 2016).
Monsanto appeals. We have subject matter jurisdiction pursuant to 28 U.S.C. § 1295(a)(4)(A) (2012). We affirm.
Background
I. The Patented Technology
Entitled “Soybean Seed and Oil Compositions and Methods of Making Same,” the ’953 patent claims a two-step process for crossing (mating) two parent soybean lines to produce soybean seeds with a modified fatty acid profile. See ’953 patent col. Ill 11. 34-67; id. col. 1 11. 31-37. The ’953 patent describes “the combination of trans-genes that provide both moderate oleic acid levels and low saturated fat levels with soybean germplasm that contains mutations in soybean genes that confer low linolenic acid phenotypes.” Id., Abstract. Claim 1, which was amended during the reexamination, is the sole independent claim and is illustrative.
It recites:
A method of obtaining a soybean plant with an altered seed oil fatty acid composition comprising the steps of:
(a) crossing a first soybean parent line having a seed oil fatty acid composition comprising a linolenic acid content of about 3% or less[
] of total seed fatty acids by weight with a second soybean parent line having a seed oil fatty acid composition wherein the i) level of oleic acid is greater than about 55% of total seed fatty acids by weight, or ii) wherein both the level of saturated fatty acid is about 8% or less of total seed fatty acids by weight and the level of oleic acid is greater than about 55% of total seed fatty acids by weight, said second soybean parent line comprising either a trans-gene that decreases the expression of an endogenous soybean FAD2-1 gene to provide the level of oleic acid greater than about 55% of total seed fatty acids by weight of said second parent soybean line of (i); or both a transgene that decreases the expression of an endogenous soybean FATB gene and a trans gene that decreases the expression of an endogenous soybean FAD2-1 gene to provide the level of saturated fatty acid of about 8% or less by weight and the level of oleic acid greater than about 55% of total seed fatty acids by weight of said second parent soybean line of (ii); and (b) obtaining a progeny[
] plant exhibiting a seed oil fatty acid composition comprising a linolenic acid content of about 3% or less of total fatty acids by weight and also comprising either i) -an oleic acid level in the range of [about] 55% to [about] 80% of total seed fatty acids by weight, or ii) both a saturated fatty acid level of about 8% or less of total seed fatty acids by weight and an oleic acid level of [about] .55% to [about] 80% of total seed fatty acids by weight, thereby obtaining a soybean plant with an altered seed oil fatty acid composition.
J.A. 329-30 (footnotes and emphases, added) (alterations in original).
II. Booth
Booth is directed toward a number of soybean crosses aimed at obtaining progeny with desired. fatty acid compositions. See Booth col. 38 1. 53-col. 45 1. 43 (exs. 5-8), col. 471. 53-col. 481. 40 (ex. 11). Similar to the 953 patent, Booth discloses a “variety of novel soybean genes that alter oil quality.” Id. col. 6 11. 40-41. Specifically, Booth Example 8 describes a method of crossing two soybean lines,’ one with a “fan allele” or D3A gene for low linolenic acid content and’the other with a D2T gene for high oleic acid content. See id; col. 251. 45-col. 26 1. 38 (Example 8: “Soybeans with High Oleic Acid and Low Linolenic Acid Content!’); see also id. tbl. 12 (showing the fatty acid makeup of the selected progeny plants).
During, the inter partes reexamination, DuPont submitted two declarations from one of Booth’s named inventors, Dr. Anthony John Kinney (together, “the Kinney Declarations”). J.A. 133-275 (First Kinney Declaration), 359-71 (Second Kinney Declaration). DuPont produced the Kinney Declarations to show data from additional progeny produced by following the disclosed method of Example 8, “including plants not selected for inclusion in Table 12 of the Booth patent.” J.A. 360 (footnote omitted). Relevant here, the PTAB relied upon the Kinney Declarations to interpret the fatty acid properties of the F2:3 generation because it found the “F2:3 generation results provided in Exhibit A of the Second Kinney,. Declaration represented] the lines of all resulting progeny” from a cross prepared according to Booth Example 8 and related Table 12 that were not included in Booth Table 12. E.I. DuPont, 2016 WL 4255131, at *4.n.9; see J.A. 360 n.1.
Discussion
Monsanto contends that thé PTAB erred by: (1) misconstruing the “about 3% or less” limitation in the ’953 patent to include progeny with a linolenic acid content of 4%, Appellant’s Br. 45-50; (2) “rejecting [the Asserted C]laims ■ for anticipation” based on “an unlawful composite” of Booth and the Kinney Declarations, the latter of which Monsanto alleges are non-prior art references, id. at 33-34 (capitalization and alterations omitted); see id. at 33-50; and (3) employing a legally erroneous “accidental obviousness theory for claim 2,” id. at 51 (capitalization and alterations omitted); see id. at 50-60. After articulating the applicable standard of review, we address these arguments in turn.
I. Standard of Review
“We review the PTAB’s factual findings for substantial evidence and its legal conclusions de novo.” Redline Detection, LLC v. Star Envirotech, Inc., 811 F.3d 435, 449 (Fed. Cir. 2015) (citation omitted). “Substantial evidence is something less than the weight of the evidence but more than a mere scintilla of evidence,” meaning that “[i]t is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” In re NuVasive, Inc., 842 F.3d 1376, 1379, 1380 (Fed. Cir. 2016) (internal quotation marks and citations omitted). If two “inconsistent conclusions may reasonably be drawn from the evidence in record, [the PTABJ’s decision to favor one conclusion over the other is the epitome of a decision that must be sustained upon review for substantial evidence.” In re Cree, Inc., 818 F.3d 694, 701 (Fed. Cir. 2016) (internal quotation marks and citation omitted).
II. Claim Construction
A, Legal. Standard
We review the PTAB’s ultimate claim construction de novo and its underlying factual findings for substantial evidence. In re CSB-Sys. Int’l, Inc., 832 F.3d 1336, 1340 (Fed. Cir. 2016) (citing, inter alia, Teva Pharm. USA, Inc. v. Sandoz, Inc., — U.S. -, 136 S.Ct. 831, 840-41, — L.Ed.2d -(2015)). “During reexamination proceedings of unexpired patents, ... the [PTAB] uses the broadest reasonable interpretation consistent with the specification standard, or BRI.” Id., 832 F.3d at 1340 (internal quotation marks and citations omitted). A specification “includes both the written description and the claims” of the patent. In re Packard, 751 F.3d 1307, 1320 n.11 (Fed. Cir. 2014). A patent’s specification, together with its prosecution history,
constitutes .intrinsic evidence to which the PTAB gives priority when it construes claims, See .Microsoft Corp. v. Proxy conn, Inc., 789 F.3d 1292, 1297-98 (Fed. Cir. 2015). When the PTAB reviews only evidence intrinsic to the patent, the PTAB’s determination will amount solely to a determination of law, which we review de novo. See In re CSB-Sys,, 832 F.3d at 13⅛. '
B. The PTAB Properly Construed the “About 3% or Less” Limitation in Step (a)
The PTAB “reasonably interpreted” Booth’s parent line containing 4% linolenic acid “to be within the scope of ‘about 3%,’ ” as recited in claim 1 step (a).
E.I. DuPont, 2016 WL 4255131, at *6.
Monsanto maintains that the PTAB’s construction is inconsistent with the specification. Appellant’s Br. 45-50; see J.A. 5006 (arguing before the PTAB that a “4% lino-lenic acid content is outside the scope of a 3% linolenic acid content” (capitalization omitted)).
We disagree.
The claim language is not instructive, so we turn to the remainder of the specification. See Marine Polymer Techs., Inc. v. HemCon, Inc., 672 F.3d 1350, 1358 (Fed. Cir. 2012). Indeed, in Phillips, we held that the specification “is the single best guide to the meaning of a disputed term.” 415 F.3d at 1315 (internal quotation marks and citation omitted). Here, the specification provides examples, which are “included to demonstrate preferred embodiments of the invention.” ’953 patent col. 29 11. 64-65. Example 9 describes a parent line designated as the “C1640 line” with “a linolenic acid content of about 3%.” Id. col. 45 1. 65; see id. col. 4511. 64-66. The specification further identifies Wilcox, J.R. et al., Inheritance of Low Linolenic Acid Content of the Seed Oil of a mutant In Glycine Max, Theoretical & Applied Genetics (1985) (“Wilcox”) as the source of this C1640 line, see id. col. 46 11. 2-5, and Wilcox states that the C1640 line has a range of linolenic acid contents from 2.3% to 4.1%, J.A. 5098. In light of this intrinsic evidence,
we agree with the PTAB’s finding that a person having ordinary skill in the art (“PHOSITA”) would reasonably consider “about 3%” to encompass a range that includes 4%. See E.I. DuPont, 2016 WL 4255131, at *6.
Monsanto’s counterargument is unavailing. Monsanto maintains that “[e]ven if it had been appropriate to construe ‘about 3% or less’ based on Wilcox rather than the specification,” the PTAB erred in “de-fin[ing] the claims based on the highest, most outlying data point for linolenic acid in Wilcox’s sample” rather than its mean and standard deviation values. Appellant’s Br. 48 (emphasis added). However, Monsanto fails to identify what qualifies as an “outlier” or cite anything in the intrinsic record contradicting the “about 3%” claim interpretation before us. See generally id. Accordingly, the PTAB did not err in its construction of the “about 3%” limitation.
III. Anticipation
A. Legal Standard
“Anticipation is a question of fact that we review for substantial evidence.” Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1341 (Fed. Cir. 2016) (citation omitted). Likewise, “[w]hether a claim limitation is inherent in a prior art reference is a question of fact.” Telemac Cellular Corp. v. Topp Telecom, Inc., 247 F.3d 1316, 1328 (Fed. Cir. 2001) (citation omitted).
“A person shall be entitled to a patent unless,” inter alia, “the invention was patented ... more than one year prior to the date of the application for patent in the United States.” 35 U.S.C. § 102(b) (2006).
A prior art reference anticipates a patent’s claim under § 102(b) if it “discloses each and every element of the claimed invention arranged or combined in the same way as in the claim.” Blue Calypso, 815 F.3d at 1341 (internal quotation marks, alterations, and citation omitted). “[Ajntieipation by inherent disclosure is appropriate only when the reference discloses prior art that must necessarily include the unstated limitation ....”. Transclean Corp. v. Bridgewood Servs., Inc., 290 F.3d 1364, 1373 (Fed. Cir. 2002) (citation omitted).
B. Substantial Evidence Supports the PTAB’s Finding that Booth Anticipates the Asserted Claims
The PTAB found that Booth anticipates the Asserted Claims, relying in part on the Kinney Declarations, which analyze Booth. The PTAB concluded that Booth discloses step (a) of claim 1 and “the Second Kinney Declaration shows that ... the progeny of plants obtained” from step (a) “as taught by Example 8 of Booth necessarily includes” plants disclosed in step (b). E.I. DuPont, 2016 WL 4255131, at *9; see id. at *18 (“[T]he evidence in the Kinney Declarations establishes that carrying out the crosses described by Booth, particularly[ ] the D2T and fan allele cross, would have necessarily resulted in progeny within the scope of claim 1.”).
Monsanto contends that the PTAB’s anticipation findings are not supported by substantial evidence because the PTAB may not rely on the Kinney Declarations and, when reviewing only intrinsic evidence, Booth Example 8 does not “inevitably produce[ ] progeny within the scope of [the Asserted C]laims.” Appellant’s Br. 36 (internal quotation marks omitted); see id. at 36-45. Monsanto also argues that, if we consider the PTAB’s findings to be based on inherent anticipation, the record does not support a finding that Booth inherently anticipates Monsanto’s claims. See id. at 35 (citing to the PTAB’s statement that Booth “necessarily includes” progeny within the claim scope as evidence of potential review for inherent anticipation but noting that the PTAB never used the term “inherent” explicitly (emphasis added)).
We disagree.
I. Substantial Evidence Supports the PTAB’s Finding that Booth Teaches Steps (a) and (b) of the Asserted Claims
Substantial evidence supports the PTAB’s finding that Booth expressly discloses step (a) of claim 1. Step (a) discloses crossing soybean lines having known genetic features—a first parent line having “about 3% or less” seed oil linolenic acid content with a second parent line having a transgene that decreases the expression of the FAD2-1 gene—and, thus, having a seed oil oleic acid content greater than about 55%. ’953 patent col. Ill 1. 39; J.A. 329.
Booth Example 8 describes crossing a first parent line containing “either a fan allele or the D3A gene” with a second line containing “the D2T gene.” Booth col. 25 11. 49-50. Table 2 of Booth identifies the fatty acid characteristics of the first parent lines that were used. Id. tbl. 2; see J.A. 135-39. Booth states that the fan allele line in Table 2 has 4% linolenic acid by weight and that the D2T line has a fatty acid content of 85%. Booth tbl. 2; see J.A. 136-37., Thus, given our claim construction above that 4% is within the “about 3%” limitation, we find that a fan allele cross of the parent line from Booth anticipates step (a) of claim 1 of the ’953 patent. We further find substantial evidence that Booth teaches that the D2T line contains a trans-gene that decreases the expression of the FAD2-1 gene, providing 85% seed oil oleic acid levels—thus meeting both the trans-gene and the “greater than about 55%” seed oil oleic acid requirement for the second parent line of the ’953 patent claim 1 step (a). See Booth .tbl. 2 (indicating D2T as having an oleic acid content of 85%— oleic being shorthanded in the table as column “18:1”); see also J.A. 137-39.
Substantial evidence also supports the PTAB’s finding that Booth “necessarily includes” step (b) of the Asserted Claims. E.I. DuPont, 2016 WL 4255131, at *7.
Step (b) requires “obtaining a progeny plant” having a seed oil fatty acid composition with low levels of linolenic acid (about 3% or less) and oleic acid levels from 55% to 80%. See ’953 patent col. Ill 11. 58-67; see also J.A. 329. Step (b) does not limit a progeny to a first generation plant. See ’953- patent col. Ill 11. 58-67; see Oral Arg. at. 5:39-41 (conceding by counsel for Monsanto that “[t]he claims don’t require any particular progeny.”). Table 12 of Booth reports seed oil fatty acid profiles of some of those progeny generation plants. See Booth tbl. 12; see also id. col. 2511. 48-65.
Monsanto argues that Booth does not anticipate step (b) of claim 1 because Table 12 does not explicitly identify a progeny with the fatty acid' by weight characteristics of claim 1 step (b), but rather identifies progeny with seed oil oleic acid contents above the ’953 patent’s claimed ranges, which “forecloses any claim' of in-herency.” Appellant’s Br. 37. As the PTAB found,' Booth “clearly [informs a PHOSI-TA] that Table 12 does not represent the full scope of the progeny lines resulting from the cross, but only represents the ‘[s]ingle plants and family means that were both lowest in linolenic acid content and highest in oleic acid content,’” E.I. DuPont, 2016 WL. 4255131, at *9 (quoting Booth col. 25 11. 61-65). Indeed, Booth expressly states that multiple generations of plants, including the “F2:3 families” generations not shown in Table 12, were obtained from the cross. See Booth col. 25 11. 48-65. Because Booth describes obtaining many progeny from the cross families of Example 8 but only reports a “select” subset of results in Table 12, E.I. DuPont, 2016 WL 4255131, at *4, the “select” subset of Table 12 does not foreelbse inheren-cy.
Inherent anticipation applies here because the “[Booth] disclosures ... must necessarily include the unstated limitation,” Transclean, 290 F.3d at 1373, i.e,, the progeny line having a seed oil fatty acid composition with low levels of linolenic acid and high levels of. oleic acid. The Second Kinney Declaration’s.D2T and fan allele cross confirm that Booth’s F2:3 generation would necessarily result in progeny within the scope of claim. 1. See J.A. 360, 364-71 (describing and., containing resultant fatty acid profile data set for seeds from the F2:3 generation from which the Booth Table 12 plants were self-pollinated to produce F3:4 progeny—of which forty-five have ah oleic acid content of 55% to 80% and a linolenic acid content of 3.5% or less, and sixteen have an oleic acid content of between 55% and- 80% by weight and a linolenic acid content of 3% or less by weight). As the PTAB explained, the Kinney Declarations confirm that the cross from step (a) “necessarily includes progeny plants that have an oleic acid concentration and a linolenic acid concentration” as claimed in step (b), E.I. DuPont, 2016 WL 4255131, at *7, such that substantial evidence demonstrates that Booth inherently anticipates step (b) of the Asserted Claims as construed.
2. The PTAB Properly Relied Upon the Kinney Declarations
Monsanto maintains that the PTAB impermissibly looked to “non-prior art data” and “secret data” by using the Kinney Declarations to support its anticipation finding. Appellant’s Br. 34; see id. at 33-36.
However, Monsanto confuses prior art with extrinsic evidence used to support what is “necessarily present” in a prior art’s teaching. Extrinsic evidence “may be used to interpret the allegedly anticipating reference and [to] shed light on what it would have meant to [a PHOSI-TA].” Cibar-Geiby Corp. v. Alza Corp., No. 95-1046, 68 F.3d 487, 1995 WL 598380, at *2 (Fed. Cir. 1995) (citation omitted); see In re Baxter Travenol Labs., 952 F.2d 388, 390 (Fed. Cir. 1991). We conclude that the PTAB did not err in relying upon the Kinney Declarations.
First, the Kinney Declarations do not expand the meaning of Booth or serve as prior art: they demonstrate what is inherent in Booth progeny with various seed oil fatty acid profiles. See J.A. 142 (“[Booth] discloses the benefits of producing an altered seed fatty acid content that favors saturated fatty acids such as oleic acid -over polyunsaturated fatty acids such.as linolenic acid to improve the health of those ingesting the soybean plant or products made from the soybean plant.”); see also J.A. 360 (“Exhibit A shows the fatty acid profiles for seeds from all of the plants resulting from cross described in [Booth] Example 8 ... including plants not selected for inclusion in Table 12 .... ” (footnote omitted)).
Second, the Kinney Declarations are not improper “secret data” simply because they were not published. The Kinney Declarations were not used as the single prior art anticipatory reference for purposes of this appeal. Instead, they were offered in support of the prior art already of record, Booth, for purposes of anticipation. It is well established that such reliance on extrinsic evidence is proper in an inherency analysis. See Telemac, 247 F.3d at 1328 (“[R]ecourse to extrinsic evidence is proper to determine whether a feature, while not explicitly discussed, is necessarily present in a reference.” (citation omitted)). Moreover, extrinsic evidence need not antedate the critical date of the patent at issue, Schering Corp. v. Geneva Pharm., Inc., 339 F.3d 1373, 1377 (Fed. Cir. 2003) (“[T]his court rejects the contention that inherent anticipation requires recognition in the prior art.”), nor have contemporaneous recognition by a PHOSITA, id. (“[Recognition by a [PHOSITA] before the critical date ... is not required to show anticipation by inherency.”). In addition, the Kinney Declarations were not secretive for purposes .of the lower proceeding. Monsanto submitted the First Kinney Declaration with its. Request . For Inter Partes Reexamination, J.A. 133, and submitted the Second Kinney Declaration in response to Monsanto’s challenge that the F2:4 generation progeny plant (from the First Kinney Declaration) represents an “outlier” for oleic acid content cited in Booth, J.A. 361 (“The 72.8% oleic acid content in Exhibit 5 of [the First Kinney Declaration] corresponding to sample 70LT-2709-0 of Table 12 is consistent with the oleic acid contents of the samples identified .... ”). Contrary to Monsanto’s assertions about a “void of evidence about the origin of that secret data,” Appellant’s Br. 42, we find the Kinney Declarations demonstrate the inherent features already in Booth’s express teachings regarding the resultant progeny characteristics.
Third, although Monsanto cites to Glaxo Inc. v. Novopharm Ltd., 52 F.3d 1043 (Fed. Cir. 1996), to support its contention that the Kinney Declarations are insufficient or ináccurate, see Appellant’s Br. 41, Glaxo is inapposite. In Glaxo, the parties disputed whether the process found in a prior art’s specification produced the claimed invention. 52 F.3d at 1047. The petitioner’s expert presented extrinsic evidence in the form of testimony on the issue of inherent anticipation; however, the patent-owner successfully rebutted the petitioner’s evidence with its own data and expert testimony. Id. Unlike Glaxo, here, Monsanto presented no rebuttal testimony. See E.I. DuPont, 2016 WL 4255131, at *5 (“Without evidence to the contrary, it is reasonable to assume that both Exhibit 5 and Exhibit A are results directed to a D2T and fan allele cross as identified by the First Kinney Declaration.”), *7 (“[Monsanto] has presented no argument or evidence to suggest that the data provided by Dr. Kinney in Exhibit A of the Second Kinney Declaration does not fairly represent actual test results from a cross prepared in Example 8 of Booth.”). To the extent Monsanto raises arguments that Example 8 would not necessarily produce progeny soybean plants each and every time within the scope of the claims on appeal, see Appellant’s Br. 20-22, we find those waived, see Singleton v. Wulff, 428 U.S. 106, 120, 96 S.Ct. 2868, 49 L.Ed.2d 826 (1976) (“It is the general rule, of course, that a federal appellate court does not consider an issue not passed upon below.”). In any event, as counsel for Monsanto agreed at oral argument, the claims do not require that the desired soybean progeny be produced each and every time. Oral Arg. at 5:34-7:19, 28:34-56. For the foregoing reasons, the PTAB did not err in relying on the Kinney Declarations.
IV. Obviousness
A patent claim is invalid as obvious “if the differences between the subject matter sought to be patented 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 [PHOSITA].” 35 U.S.C. § 103(a) (2006).
Obviousness is a question of law based on underlying findings of fact. See In re Gartside, 203 F.3d 1305, 1316 (Fed. Cir. 2000).
“[Although anticipation can be proven inherently, proof of inherent anticipation is not the same as proof of obviousness.” Cohesive Techs., Inc. v. Waters Corp., 543 F.3d 1351, 1364 (Fed. Cir. 2008). “Though less common, in appropriate circumstances, a patent can be obvious in light of a single prior art reference if it would have been obvious to modify that reference to arrive at the patented invention.” Arendi S.A.R.L. v. Apple Inc., 832 F.3d 1355, 1361 (Fed. Cir. 2016), cert, denied sub nom. Google Inc. v. Arendi S.A.R.L., — U.S. -, 137 S.Q. 1329, 197 L.Ed.2d 517 (2017). This court has “repeatedly held that the motivation to modify a prior art reference to arrive at the claimed invention need not be the same motivation that the patentee had.” Alcon Research, Ltd. v. Apotex Inc., 687 F.3d 1362, 1368 (Fed. Cir. 2012).
B. Substantial Evidence Supports the PTAB’s Finding of Obviousness Related to Claim 2
Dependent claim 2 limits the claim 1 step (b) progeny plant to specific percentage ranges of linolenic, oleic, and seed oil fatty acid levels, requiring that a step (b) progeny plant have a seed oil linolenic acid content “of about 1% to about 3%” by weight, an “oleic acid content of ... 65% to ... 80%” by weight, and a seed oil saturated fatty acid level of “about 1.5% to about 8%” by weight. J.A. 330. The PTAB affirmed the Examiner’s rejection of claim 2 on grounds that “claim 2 would have been obvious” while basing its factual findings in large part upon its prior anticipation findings for similar claim 29.
E.I. DuPont, 2016 WL 4255131, at *8 (“Although the Examiner did not include claim 2 in the anticipation rejection ..., [Monsanto] does not dispute [line 70LT-IP36102-20 of the Second Kinney Declaration] falls within the scope of [the claim 2 limitation] ‘about 3%’ by weight.” (citation omitted)).
. The PTAB reasoned that a PHOSITA would have a reasonable expectation of success in performing the D2T or fan allele cross. See E.I. DuPont, 2016 WL 4255131, at *8-9.
Our findings with respect to anticipation apply equally here. See supra Section III.B. As such, the Second Kinney Declaration’s disclosure of a progeny (70LT-IP36102-20) with a saturated acid content of about 8% by weight, an oleic acid content of 80% by weight, and a linolenic acid content of 3.4% by weight is substantial evidence to support the finding of obviousness. See J.A. 370; see also J.A. 275, 359-71. Therefore, the sole remaining issue concerns whether a PHOSITA would have been motivated to modify Booth to arrive at the patented invention. See Arendi S.A.R.L., 832 F.3d at 1361.
Despite Monsanto’s contentions to the contrary, see Appellant’s Br. 52, we find substantial evidence supports the PTAB’s determination that a PHOSITA would have been motivated to combine elements of Booth. The PTAB did not base its obviousness finding solely on its inherent anticipation analysis.
The PTAB explained that a PHOSITA would have been motivated to modify Booth to produce plants having more variable seed oil fatty acid characteristics, as found in claim 2 of the ’953 patent, because Booth “only represents the ‘[s]ingle plants and family means that were both lowest in linolenic acid content and highest in oleic acid content.’ ” E.I. DuPont, 2016 WL 4255131, at *9 (quoting Booth col. 25 11. 61-65)). The PTAB then “f[ou]nd this evidence sufficiently teaches [a PHOSITA] that the progeny results also include! ] plants that have higher linolenic acid content-and/or lower-oleic .acid content.” Id. Monsanto points to no statement or suggestion in Booth that it would be undesirable to: produce progeny having low seed oil levels of linolenic acid and 65% to 80% oleic acid (i.e., the composition recited in claim 2). See generally Appellant’s Br. Accordingly, we uphold the PTAB’s conclusion that claim 2 would have been obvi-. ous over Booth.
Conclusion
We have considered Monsanto’s remaining arguments and find them unpersuasive. Accordingly, the Decision on Appeal of the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board is
AFFIRMED
