PRATS, JOHN E. SCHNEIDER, and TIMOTHY G. MAJORS, Administrative Patent Judges. PRATS, Administrative Patent Judge. DECISION ON APPEAL This appeal under 35 U.S.C. § 134 involves claims to methods that analyze the genomic DNA of pre-implantation human embryos produced by in vitro fertilization. The Examiner rejected the claims for indefiniteness and obviousness. We have jurisdiction under 35 U.S.C. § 6(b). We reverse the Examiner's indefiniteness rejections, but affirm the obviousness rejection. 1 Appellant states that the real party in interest "the assignee, BlueGnome Limited, a wholly owned subsidiary of Illumina, Inc." Appeal Br. 3. Appeal 2018-008186 Application 12/093,912 STATEMENT OF THE CASE The following rejections are before us for review: (1) Claims 20, 63, 67-72, 75, 76, and 79-83, rejected under 35 U.S.C. § 112, second paragraph, as being indefinite (Ans. 3-5); and (2) Claims 20, 63, 67-72, 75, 76, and 79-83, rejected under 35 U.S.C. § 103 (a) as being unpatentable over Handyside, 2 Lareu, 3 admitted prior art, Makarov, 4 Dhallan I, 5 and Dhallan II6 (Ans. 5-14). Claims 63 and 79 are the independent claims on appeal, and read as follows: 63. A method comprising: (a) removing one to five cells from a pre- implantation human embryo resulted from in vitro fertilization (IVF); (b) isolating genomic DNA from at least one human target cell, wherein the at least one human target cell consists of the one to five cells removed from the pre- implantation human embryo resulted from IVF; ( c) detecting by oligonucleotide chip or oligonucleotide microarray the genotype of at least 2,500 biallelic single nucleotide polymorphisms (SNPs) in the genomic DNA isolated from the at least one human target cell, wherein detecting by oligonucleotide chip or 2 A.

Appeal Br., Claims App'x, 1--4. INDEFINITENESS The Examiner's Prima Facie Case The Examiner concluded that independent claims 63 and 79 "are indefinite with respect to what steps are encompassed by 'detecting by oligonucleotide chip or oligonucleotide microarray the genotype' as a chip and a microarray are not processes, but are seemingly are to be used in an otherwise undefined method." Ans. 3. The Examiner concluded that independent claims 63 and 79 are also indefinite because the term "oligonucleotide" could be construed to have multiple meanings, when consulting the Specification and the prior art. Id. at 4--5. 4 Appeal 2018-008186 Application 12/093,912 Analysis As stated inJn re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992): [T]he examiner bears the initial burden ... of presenting a prima facie case of unpatentability .... After evidence or argument is submitted by the applicant in response, patentability is determined on the totality of the record, by a preponderance of evidence with due consideration to persuasiveness of argument. Appellant persuades us that the preponderance of the evidence does not support the Examiner's prima facie case of indefiniteness. Both claims 63 and 79 recite the step of "detecting by oligonucleotide chip or oligonucleotide microarray the genotype of at least 2,500 biallelic single nucleotide polymorphisms (SNPs) in the genomic DNA isolated from the at least one human target cell." Appeal Br., Claims App'x 1 (claim 63); id. at 3 ( claim 79). As Appellant points out, and the Examiner does not dispute, Appellant's Specification discloses a number of methods by which an oligonucleotide chip or oligonucleotide array may be used to detect the genotype of at least 2,500 biallelic single nucleotide polymorphisms (SNPs) in the genomic DNA isolated from the at least one human target cell. See, e.g., Spec. 13-14. Indeed, as discussed below, the Examiner relies on these disclosures in asserting the obviousness of the processes recited in claims 63 and 79. As we understand it, the Examiner's rejection is based on the fact that the language "detecting by oligonucleotide chip or oligonucleotide microarray" in claims 63 and 79 encompasses many different methods by which an oligonucleotide chip or microarray may be used to detect the claim-recited genotype. See Ans. 16-17 (arguing that it is unclear which 5 Appeal 2018-008186 Application 12/093,912 species of process encompassed by the language at issue are encompassed by claims 63 and 79). We are not persuaded. A claim does not comply with 35 U.S.C. § 112, second paragraph, "when it contains words or phrases whose meaning is unclear." In re Packard, 751 F.3d at 1310, 1314 (Fed. Cir. 2014) (approving, for pre- issuance claims, the standard from MPEP § 2173.05(e)); see also Ex parte McAward, Appeal 2015-006416, 2017 WL 3669566, at *5 (PTAB Aug. 25, 2017) (precedential) (adopting the approach for assessing indefiniteness approved by the Federal Circuit in Packard). That is, "claims are required to be cast in clear-as opposed to ambiguous, vague, indefinite-terms." Packard, 751 F.3d at 1313 It is well settled, however, that that "breadth is not to be equated with indefiniteness." In re Miller, 441 F.2d 689, 693 (CCPA 1971). In the present case, claims 63 and 79 encompass any process that uses an oligonucleotide chip or oligonucleotide microarray to detect the genotype of at least 2,500 biallelic single nucleotide polymorphisms (SNPs) in the genomic DNA isolated from at least one human target cell. Thus, although the language at issue might be broad, we are not persuaded that the scope of the language at issue is unclear or ambiguous. We, therefore, reverse the Examiner's rejection of claims 63 and 79, and their dependent claims as being indefinite based on the language "detecting by oligonucleotide chip or oligonucleotide microarray the genotype of at least 2,500 biallelic single nucleotide polymorphisms (SNPs) in the genomic DNA isolated from the at least one human target cell." As noted above, the Examiner also concluded that independent claims 63 and 79 are indefinite because the term "oligonucleotide" can be construed 6 Appeal 2018-008186 Application 12/093,912 to have multiple meanings, when consulting the Specification and the prior art. Ans. 4--5. Again, we are not persuaded. Both claims 63 and 79 recite using an "oligonucleotide chip or oligonucleotide microarray" to detect the genotype of at least 2,500 biallelic SNPs. Appeal Br., Claims App'x 1 (claim 63); id. at 3 (claim 79). It is well settled that during examination, the PTO must interpret terms in a claim using "the broadest reasonable meaning of the words in their ordinary usage as they would be understood by one of ordinary skill in the art, taking into account whatever enlightenment by way of definitions or otherwise that may be afforded by the written description contained in the applicant's specification." In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997). Thus, although it might be true, as the Examiner contends, that the prior art includes definitions of "oligonucleotide" that vary in breadth, the proper legal scope of the term is the broadest reasonable interpretation consistent with the Specification. Again, the fact that the claim language might be broad does not persuade us that it is indefinite. See Miller, 441 F.2d at 693. As noted above, moreover, Appellant's Specification provides a number of examples of oligonucleotide chips and microarrays that may be used in the claimed invention. See Spec. 14. In light of the multiple examples in the prior art of products encompassed by the language at issue, the Examiner does not persuade us that a skilled artisan would fail to understand the scope of the terms "oligonucleotide chip" or "oligonucleotide microarray." We, therefore, reverse the Examiner's rejection of the term "oligonucleotide" as indefinite. 7 Appeal 2018-008186 Application 12/093,912 OBVIOUSNESS The Examiner's Prima Facie Case In rejecting claims 20, 63, 67-72, 75, 76, and 79-83 for obviousness, the Examiner cited Handyside as disclosing the claimed steps of removing one to five cells from a pre-implantation !VF-produced embryo, isolating genomic DNA from those cells, and subsequently amplifying and analyzing the genomic DNA. See Ans. 8-9. The Examiner conceded that Handyside' s process differed from the claimed process in that Handyside did not describe screening thousands of SNPs, nor did Handyside describe collecting or analyzing a DNA sample from the father. Id. at 9. The Examiner cited Lareu as evidence that it was known in the art to use microarray analysis to evaluate paternal genomic DNA, for example in paternity testing. Id. As evidence that an ordinary artisan would have been prompted to screen for at least 2,500 SNPs when analyzing the genome of a pre- implantation !VF-produced embryo, the Examiner cited Makarov as disclosing that it was known in the art to detect thousands or even millions of SNPs when analyzing a tissue sample. Id. at 11. The Examiner cited admitted prior art disclosed in Appellant's Specification as evidence that methods of analyzing genomic DNA for over 2,500 SNPs were conventional in the art. Id. at 9-11. The Examiner cited Dhallan I as evidence that, when using SNP microarrays to detect fetal chromosomal abnormalities, it was desirable to isolate maternal DNA, as recited in Appellant's claims, and also desirable to examine all chromosomes when performing the microarray SNP analysis. Id. at 11-12. 8 Appeal 2018-008186 Application 12/093,912 The Examiner cited Dhallan II as evidence that, when using SNP microarrays to detect fetal chromosomal abnormalities, it was desirable to isolate both maternal DNA and paternal DNA, as recited in Appellant's claims, when performing the microarray SNP analysis. Id. Based on the references' combined teachings, the Examiner concluded: In view of the well-developed state of the art at the time of filing and the commercial availability for not only kits to isolate DNA from cells, but also the commercial availability of microarrays and oligonucleotide chips, and the commercial availability of software that would enable the assigning of notional SNP haplotypes to an individual, it would have been obvious to one of ordinary skill in the art at the time of filing to have modified the method of Handyside et al., such that it was expanded to test not only sex chromosomes, but to test up to all human chromosomes for SNP in cells derived from the maternal, paternal, and embryonic sources, and to detect any desired number of SNPs, be it in the thousands or tens of thousands, and wherein the SNPS occur in less than 500 bp from one another, and as a result of having identified the presence of SNPs, to then assign a notional SNP haplotype based on the detected and inherited SNPs present. Id. at 13-14. The Examiner reasoned: In view of the intense interest in early identification of embryos that may be at risk of developing diseases and/or syndromes, e.g., trisomy, said ordinary artisan would have been amply motivated. And given the well-developed state of the art and commercial availability of requisite reagents, said ordinary artisan would have had a most reasonable expectation of success. Id. at 14. 9 Appeal 2018-008186 Application 12/093,912 Analysis Having carefully considered all of the evidence and arguments presented by Appellant and the Examiner, Appellant does not persuade us that the preponderance of the evidence fails to support the Examiner's conclusion of obviousness. Appellant contends that the Examiner did not "clearly articulate any reason for a person having ordinary skill in the art to detect the genotype of at least 2,500 biallelic SNPs on at least 10 chromosomes. (See, e.g., independent claims 63 and 79. )" Appeal Br. 18. Appellant contends that the Examiner also did not "clearly articulate any reason to detect 'by oligonucleotide chip or oligonucleotide microarray the genotype' of the same 'at least 2,500 biallelic SNPs' in genomic DNA isolated from a cell of a pre-implantation human embryo resulting from IVF, maternal genomic DNA, and paternal genomic DNA." Id.; see also id. at 19--20 (reiterating same arguments). The Examiner responds by reiterating that, given the interest in analyzing the genetic material of a pre-implantation !VF-produced embryo as taught in Handyside, an ordinary artisan would have been "motivated to have used commercially-available means that would enable the detection of 10,000 SNPs on an oligonucleotide array, [and] SNPs that span some 22 chromosomes ... as such would require no further research and development." Ans. 22; see also id. at 29 ("Given the intense interest in detecting SNPs and well-developed state of the art, one of ordinary skill in the art would be highly motivated to determine the genotype of an individual via detection of thousands of SNPs across the genome of an individual."). Appellant replies: 10 Appeal 2018-008186 Application 12/093,912 [ A ]n articulation of a teaching or motivation to perform parts of the claimed methods falls short of identifying any teaching or motivation to detect at least 2,500 SNPs in genomic DNA isolated from a cell of a pre-implantation human embryo resulting from IVF, the same at least 2,500 SNPs in maternal genomic DNA, and the same at least 2,500 SNPs in paternal genomic DNA. Reply Br. 4. We find that the preponderance of the evidence supports the Examiner's conclusion of obviousness. As the Supreme Court has explained, in determining whether the prior art supplies a reason for practicing the claimed subject matter, the analysis "need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ." KSR Int 'l Co. v. Teleflex Inc., 550 U.S. 398,418 (2007); see also id. at 421 ("A person of ordinary skill is ... a person of ordinary creativity, not an automaton."). In the present case, as the Examiner found, and as required by Appellant's claim 63, Handyside discloses a process in which a cell is removed from a pre-implantation !VF-produced embryo, genomic DNA is isolated therefrom, the genomic DNA is amplified, and the amplified DNA is analyzed. Handyside 7 68 ("Two female embryos were transferred after in vitro fertilization (IVF), biopsy of a single cell at the six- to eight-cell stage, and sexing by DNA amplification of a Y chromosome-specific repeat sequence. Both women are confirmed as carrying normal female twins."). Handyside explains that the determination of the genomic sequences of the embryo allows couples at risk of transmitting certain genetic diseases to ensure that their !VF-produced offspring lack the genetic disorder: 11 Appeal 2018-008186 Application 12/093,912 Id. Diagnosis of genetic defects in preimplantation embryos would allow those unaffected to be identified and transferred to the uterus[]. ... Five couples at risk of transmitting recessive X- linked diseases, including X-linked mental retardation, adrenoieukodystrophy, Lesch-Nyhan syndrome and Duchenne muscular dystrophy (DMD) were counselled about the possibility of having preimplantation embryos sexed after IVF and those identified as females replaced in the uterus. Given Handyside' s disclosure of the desirability of determining the presence of sequences of genomic DNA indicative of genetic disorders in pre-implantation !VF-produced embryos, we agree with the Examiner that Handyside suggests that it would have been desirable to ascertain the presence of as many undesirable sequences as possible, when evaluating the genomic DNA of pre-implantation !VF-produced embryos. As the Examiner found, although Handyside does not disclose performing microarray-based analysis of over 2,500 SNPs in at least 10 chromosomes as recited in Appellant's claim 63, Dhallan I discloses that, when performing microarray-based SNP analysis of a fetal subject to determine the presence of chromosomal abnormalities, it is useful to perform an analysis of all of the subject's chromosomes, as well as maternal DNA. See Dhallan I ,r 1244 ("Fetal chromosomal abnormalities are determined by analyzing SNPs wherein the maternal template DNA is homozygous and the template DNA obtained from the plasma is heterozygous. Plasma that is isolated from blood of a pregnant female contains both maternal template DNA and fetal template DNA."); id. ,r 1245 ("A DNA microarray can be designed to contain SNPs located on the chromosome or chromosomes of interest including but not limited to ... a DNA microarray containing SNPS 12 Appeal 2018-008186 Application 12/093,912 located on each of the autosomal chromosomes and each of the sex chromosomes .... "). As the Examiner found, Makarov discloses that when performing a microarray-based analysis of a subject's genomic DNA, it is useful to evaluate multiple thousands of SNPs: For purposes of detecting a large number of SNPs ( e.g., thousands, tens of thousands, hundreds of thousands, or millions) from a single tissue sample, the original DNA sample must be amplified many times to provide sufficient material for analysis .... Locus-independent amplification of the entire genomic library (amplification en masse) is an important step in detection of genome polymorphisms, because it increases the number of copies of the molecules which increases the number of SNP assays that can be performed given a limited amount of DNA collected from an individual human .... Makarov ,r 391 (emphasis added). Makarov explains: Single nucleotide polymorphisms (SNPs) are important markers for the identification of genomic regions associated with complex diseases in humans. . . . There are likely over 10 million SNPs in the human genome, and analysis of even 1 % of all human variations (100,000 SNPs) would result in a high- resolution whole genome molecular fingerprint that can be used to uniquely identify an individual. Id. ,I 72. As the Examiner found, moreover, Dhallan II discloses that when using microarray-based techniques to determine the presence of genetic disorders or chromosomal abnormalities in a fetal subject based on SNP analysis, it is useful to also determine the corresponding sequences in both maternal and paternal DNA: In some embodiments, prior to determining the sequence of the locus of interest on fetal DNA, the sequence of the locus of 13 Appeal 2018-008186 Application 12/093,912 interest on maternal template DNA was determined. In some embodiments, prior to determining the sequence of the locus of interest on fetal DNA, the sequence of the locus of interest on paternal template DNA was determined. In some embodiments, the locus of interest is a single nucleotide po 1 ymorp hism. Dhallan II ,r 58. Given that many thousands of SNPs associated with genetic disorders and/or chromosomal abnormalities were known in the art (Dhallan I, Makarov), and given that it was known to be useful to ascertain the maternal and paternal genotypes when determining the presence of a genetic disorder and/or chromosomal abnormality in a fetus (Dhallan II), we agree with the Examiner that an ordinary artisan evaluating the genotype of a pre- implantation !VF-produced embryo as taught in Handyside, being a person of ordinary creativity, had a good reason for, and a reasonable expectation of success in, evaluating as many SNPs as possible, including over 2,500, in both the embryo and the parents, to ensure the absence of genetic disorders and/or chromosomal abnormalities in the embryo, before implantation in the uterus. Given these teachings in the art identified by the Examiner, Appellant does not persuade us that the Examiner failed to articulate a sufficient prior art-based basis for performing a process having all of the steps and features recited in Appellant's claim 63. Moreover, because the Examiner's prima facie case relies on identified teachings in the prior art, Appellant does not persuade us (see Appeal Br. 21-22; Reply 4--5) that the Examiner's prima facie case of obviousness relies on improper hindsight gleaned from Appellant's Specification. 14 Appeal 2018-008186 Application 12/093,912 In sum, for the reasons discussed, Appellant does not persuade us that the preponderance of the evidence fails to support the Examiner's prima facie case of obviousness as to claim 63. We, therefore, affirm the Examiner's obviousness rejection of claim 63, and its dependent claims, which were not argued separately. See 37 C.F.R. § 4I.37(c)(l)(iv). Appellant argues that the Examiner "provided no articulation why a person having skill in the art at the time of the invention would have detected whether the SNP genotype is AA, AB, or BB, or absent for each of at least 2,500 biallelic SNPs." Appeal Br. 20-21. Accordingly, Appellant contends, "[ fJor this additional reason, Appellant submits that the Examiner failed to clearly articulate why each element of the method of claim 79 was taught or was obvious in light of the cited prior art .... " Id. at 21. The Examiner responds that, as evidenced by the cited prior art, "the aspect of isolating genomic DNA, be it from the 'human target cell', the mother, or the father was all well known in the art." Ans. 25. Additionally, the Examiner contends, "the aspect of detecting SNPs in the genomic DNA, as well as determining fetal chromosomal abnormalities was known in the art. Such teachings speak directly to detecting/determining if the genotype is AA, AB, BB, or absent (limitation of claim 79)." Id. We find that a preponderance of the evidence supports the Examiner's position. We first note that, under our rules, to present separate argument regarding claims, "[ u ]nder each heading identifying the ground of rejection being contested, any claim( s) argued separately or as a subgroup shall be argued under a separate subheading that identifies the claim(s) by number." 37 C.F.R. § 4I.37(c)(l)(iv) (emphasis added). Appellant has not 15 Appeal 2018-008186 Application 12/093,912 provided separate a subheading as required by rule and, therefore, has not properly presented a separate argument as to claim 79. In any event, as noted above, Dhallan II discloses that it was useful to ascertain the maternal and paternal genotypes when determining the presence of a genetic disorder and/or chromosomal abnormality in a fetus. See Dhallan II ,r 58. Handyside, moreover, discloses the desirability of knowing the genomic makeup of parents of a pre-implantation IVF- produced embryo that is, knowing whether the parents are potential carriers of a genetic disorder. See Handyside 7 68 ( describing counselling "[ f]ive couples at risk of transmitting recessive X-linked diseases"). Given the teachings cited above as to the desirability of ascertaining the presence in pre-implantation !VF-produced embryos of SNPs indicative of genetic disorders and chromosomal abnormalities, we discern no error in the Examiner's finding that an ordinary artisan, being a person of ordinary creativity, had a good reason for determining whether the subject was homozygous or heterozygous for a particular allele, that is, whether the subject was AA, AB, BB, or lacked a particular genotype associated with a particular disorder or abnormality. Similarly, given the interest in knowing the corresponding genotype in the parents, as suggested by both Dhallan II and Handyside, we discern no error in the Examiner's finding that an ordinary artisan had a good reason for determining whether the parents of an !VF-produced embryo undergoing genetic analysis were homozygous or heterozygous for a particular allele, that is, whether the parents were AA, AB, BB, or lacked a particular genotype associated with a particular disorder or abnormality. 16 Appeal 2018-008186 Application 12/093,912 Because Appellant does not persuade us, therefore, that the combination of references cited by the Examiner fails to suggest a process having all of the steps and features recited in Appellant's claim 79, we affirm the Examiner's obviousness rejection of claim 79. Because they were not argued separately, those claims depending from claim 79 fall with claim 79. DECISION For the reasons discussed, we reverse the Examiner's indefiniteness rejections. For the reasons discussed, we affirm the Examiner's obviousness rejection. TIME PERIOD No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). AFFIRMED 17 Copy with citationCopy as parenthetical citation
