Office Action

§101 §103 §DP
DETAILED ACTION 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on February 2, 2026 has been entered. Applicant’s remarks and amendments have been fully and carefully considered but are not found to be sufficient to put the application in condition for allowance. Claims 59 and 61-68 are currently pending and have been examined herein. Claim Rejections - 35 USC § 101 3. 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 59 and 61-68 are rejected under 35 U.S.C. 101 because the claimed invention is directed to judicial exception without significantly more. The claims have been evaluated using the 2019 Revised Patent Subject Matter Eligibility Guidance (see Federal Register Vol. 84, No. 4 Monday, January 7, 2019). Step 1: The claims are directed to the statutory category of a process. Step 2A, prong one: Evaluate Whether the Claim Recites a Judicial Exception Claim 59 recites the following limitation: (3) detecting, using a computer, Indicator CA regions in the genomic sequence, wherein Indicator CA regions comprise Indicator loss of heterozygosity (LOH) Regions, Indicator telomeric allelic imbalance (TAI) Regions, and Indicator large scale transitions (LSTs), wherein (a) an Indicator LOH Region is an LOH Region that is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located; (b) an Indicator TAI Region is a TAI Region with allelic imbalance that (1) extends to one of the subtelomeres, (i1) does not cross the centromere and (iii) is longer than 1.5 megabases; and (c) an Indicator LST is a ploidy-adjusted somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length. Claim 68 recites the following limitation: (3) detecting, using a computer, Indicator CA regions in the genomic sequence, wherein Indicator CA regions comprise Indicator loss of heterozygosity (LOH) Regions, Indicator telomeric allelic imbalance (TAI) Regions, and Indicator large scale transitions (LSTs), wherein (a) an Indicator LOH Region is an LOH Region that is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located; (b) an Indicator TAI Region is a TAI Region with allelic imbalance that (1) extends to one of the subtelomeres, (i1) does not cross the centromere and (iii) is longer than 1.5 megabases; and (c) an Indicator LST is a region comprising a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length. The instant claims recite abstract ideas. The claims recite two types of abstract ideas that have been identified in the guidance. The first type of abstract idea is a mental process. The “detecting” step, as recited in claims 59 and 68, is a process that, under its broadest reasonable interpretation, covers performance of the limitation in the mind but for the recitation of a generic computer. That is, other than reciting “using a computer,” nothing in the claim precludes the determining step from practically being performed in the human mind. Except for the “using a computer” language, the claim encompasses the user reading nucleic acid sequences and thinking about whether the nucleic acid sequences meet the criteria set forth in the claims for a LOH, TAI, and LST region. It is noted that the amount of base pairs that would need to be analyzed and the amount of time required to perform the analysis, is irrelevant for determining whether that procedure is a mental process: "the fact that the required calculations could be performed more efficiently via a computer does not materially alter the patent eligibility of the claimed subject matter. ... Using a computer to accelerate an ineligible mental process does not make that process patent-eligible" (Bancorp v. Sun Life, 103 USPQ2d 1425 at 1433-1434 (CAFC 2012)). MPEP 2106.04(a)(2)(III)(A) states that claims recite a mental process when they contain limitations that can practically be performed in the human mind, including for example, observations, evaluations, judgments, and opinions. Examples of claims that recite mental processes include: a claim to “collecting information, analyzing it, and displaying certain results of the collection and analysis,” where the data analysis steps are recited at a high level of generality such that they could practically be performed in the human mind, Electric Power Group v. Alstom, S.A., 830 F.3d 1350, 1353-54, 119 USPQ2d 1739, 1741-42 (Fed. Cir. 2016); claims to “comparing BRCA sequences and determining the existence of alterations,” where the claims cover any way of comparing BRCA sequences such that the comparison steps can practically be performed in the human mind, University of Utah Research Foundation v. Ambry Genetics, 774 F.3d 755, 763, 113 USPQ2d 1241, 1246 (Fed. Cir. 2014); a claim to collecting and comparing known information (claim 1), which are steps that can be practically performed in the human mind, Classen Immunotherapies, Inc. v. Biogen IDEC, 659 F.3d 1057, 1067, 100 USPQ2d 1492, 1500 (Fed. Cir. 2011) Further MPEP 2106.04(a)(2)(III)(C) states that a claim that requires a computer may still recite a mental process when the computer is generic. An example of a case identifying a mental process performed on a generic computer as an abstract idea is Voter Verified, Inc. v. Election Systems & Software, LLC, 887 F.3d 1376, 1385, 126 USPQ2d 1498, 1504 (Fed. Cir. 2018). In this case, the Federal Circuit relied upon the specification in explaining that the claimed steps of voting, verifying the vote, and submitting the vote for tabulation are “human cognitive actions” that humans have performed for hundreds of years. The claims therefore recited an abstract idea, despite the fact that the claimed voting steps were performed on a computer. 887 F.3d at 1385, 126 USPQ2d at 1504. Another example is Versata, in which the patentee claimed a system and method for determining a price of a product offered to a purchasing organization that was implemented using general purpose computer hardware. 793 F.3d at 1312-13, 1331, 115 USPQ2d at 1685, 1699. The Federal Circuit acknowledged that the claims were performed on a generic computer, but still described the claims as “directed to the abstract idea of determining a price, using organizational and product group hierarchies, in the same way that the claims in Alice were directed to the abstract idea of intermediated settlement, and the claims in Bilski were directed to the abstract idea of risk hedging.” 793 F.3d at 1333; 115 USPQ2d at 1700-01. The second type of abstract idea is mathematical concepts. The claims state that a LOH region is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH region is located. The claims state that a TAI region has allelic imbalance that (i) extends to one of the subtelomeres, (ii) does not cross the centromere and (iii) is longer than 1.5 megabases. The claims state that a LST region comprises a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length. Determining that something is "greater than" (in this case longer than) or "less than" (in this case shorter than) is a fundamental math question, as it involves comparing the magnitude of numbers and is a core concept in arithmetic, algebra, and inequalities. Thus the claims recite a mathematical relationship, more specifically, a comparison relationship expressed as an inequality. Further claim 58 recites that the LST region is “ploidy-adjusted”. The specification teaches that the LST Region Score can be modified by adjusting it by ploidy: LSTm=LST-kP, where P is ploidy and k is a constant (in some embodiments, k=15.5) (see paras 0056 and 0351). Thus detecting an Indicator LST that is ploidy adjusted requires performing a mathematical calculation. Step 2A, prong two: Evaluate Whether the Judicial Exception Is Integrated Into a Practical Application The claims do NOT recite additional steps or elements that integrate the recited judicial exceptions into a practical application of the exception(s). For example, the claims do not practically apply the judicial exception by including one or more additional elements that the courts have stated integrate the exception into a practical application: An additional element reflects an improvement in the functioning of a computer, or an improvement to other technology or technical field; An additional element that applies or uses a judicial exception to effect a particular treatment or prophylaxis for a disease or medical condition; An additional element implements a judicial exception with, or uses a judicial exception in conjunction with, a particular machine or manufacture that is integral to the claim; An additional element effects a transformation or reduction of a particular article to a different state or thing; and An additional element applies or uses the judicial exception in some other meaningful way beyond generally linking the use of the judicial exception to a particular technological environment, such that the claim as a whole is more than a drafting effort designed to monopolize the exception. In addition to the judicial exceptions the claims require (1) contacting a ovarian, lung or esophageal cancer cell sample with at least 500 oligonucleotide probes capable of hybridizing to a plurality of polymorphic regions of human genomic DNA; and (2) sequencing, by a sequencer, the human genomic DNA. These steps are not considered to integrate the judicial exception into a practical application because they merely add insignificant extra-solution activity (data gathering) to the judicial exception. Step 2B: Evaluate Whether the Claim Provides an Inventive Concept In addition to the judicial exceptions the claims require (1) contacting a ovarian, lung or esophageal cancer cell sample with oligonucleotide probes capable of hybridizing to a plurality of polymorphic regions of human genomic DNA; and (2) sequencing, by a sequencer, the human genomic DNA. These steps do not amount to significantly more because they simply append well understood, routine, and conventional activities previously known in the art, specified at a high level of generality, to the judicial exceptions. In the instant case the teachings in the specification demonstrate the well understood, routine, conventional nature of additional elements because it teaches that the additional elements are well known or commercially available. For example the specification teaches the following: [0105] As described herein, identifying CA loci (as well as the size and number of CA Regions) can include, first, determining the genotype of a sample at various genomic loci (e.g., SNP loci, individual bases in large-scale sequencing) and, second, determining whether the loci exhibit any of LOH, TAI or LST. Any appropriate technique can be used to determine genotypes at loci of interest within the genome of a cell. For example, single nucleotide polymorphism (SNP) arrays (e.g., human genome-wide SNP arrays), targeted sequencing of loci of interest (e.g., sequencing SNP loci and their surrounding sequences), and even large-scale sequencing (e.g., whole exome, transcriptome, or genome sequencing) can be used to identify loci as being homozygous or heterozygous. [0110] In some cases, targeted sequencing of known polymorphic loci (e.g., SNPs and surrounding sequences) can be done as an alternative to microarray analysis. For example, the genomic DNA can be enriched for those fragments containing a locus (e.g., SNP location) to be analyzed using kits designed for this purpose (e.g., Agilent SureSelect™, Illumina TruSeq Capture™, and Nimblegen SeqCap EZ Choice™). For example, genomic DNA containing the loci to be analyzed can be hybridized to biotinylated capture RNA fragments to form biotinylated RNA/genomic DNA complexes. Alternatively, DNA capture probes may be utilized resulting in the formation of biotinylated DNA/genomic DNA hybrids. Streptavidin coated magnetic beads and a magnetic force can be used to separate the biotinylated RNA/genomic DNA complexes from those genomic DNA fragments not present within a biotinylated RNA/genomic DNA complex. The obtained biotinylated RNA/genomic DNA complexes can be treated to remove the captured RNA from the magnetic beads, thereby leaving intact genomic DNA fragments containing a locus to be analyzed. These intact genomic DNA fragments containing the loci to be analyzed can be amplified using, for example, PCR techniques. The amplified genomic DNA fragments can be sequenced using a high-throughput sequencing technology or a next-generation sequencing technology such as Illumina HiSeq™, Illumina MiSeq™, Life Technologies SoLID™ or Ion Torrent™, or Roche 454™ Additionally the prior art demonstrates the well understood, routine, conventional nature of additional elements because it teaches that the additional elements are well known or commercially available. For example Mertes (Briefings in Functional Genomics, Vol 10, Issue 6, November 2011 pages 374-386) is a review article that discusses the latest targeted enrichment methods and aspects of their utilization along with second-generation sequencing for complex genome analysis (abstract). Mertes teaches that hybrid capture is a technique for targeted enrichment. Mertes teaches that in this technique nucleic acid strands derived from the input sample are hybridized specifically to preprepared DNA fragments complementary to the targeted regions of interest, either in solution or on a solid support, so that one can physically capture and isolate the sequences of interest (page 375, 377). Mertes teaches that recently, an increasing number of protocols and vendors have begun offering out of the box solutions for hybrid capture, meaning, the researcher need not do development work but merely choose between a preset targeted enrichment regions (e.g. whole exome) or specify their own custom enrichment region. Example vendors include: Agilent (SureSelect product), NimbleGen (SeqCap EZ product), Flexgen and MycroArray (page 379). Mertes teaches that following targeted enrichment the DNA is sequenced using a sequencer (page 374-375). Further it is noted that the courts have recognized the following laboratory techniques as well-understood, routine, conventional activity in the life science arts when they are claimed in a merely generic manner (e.g., at a high level of generality) or as insignificant extra-solution activity.

Cir. 2014) For the reasons set forth above the claims are not directed to patent eligible subject matter. Response To Arguments 4. In the response the Applicants traversed the rejection under 35 USC 101. Regarding Step 2A Prong 1, the Applicants argue that the claims do not recite abstract ideas. They argue that recitation that certain genomic features, such as Indicator LOH Regions, are “longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located” is not a “fundamental math question”, but rather a physical description of a nucleic acid in question. It simply cannot be that case that any claim reciting the physical size or dimensions of a claimed element is reciting a “fundamental math question”, merely because the reader must consider the relative size parameters. They argue that the claims do not “recite” a judicial exception and at worst “involve” mathematical concepts without specifically claiming them (the “ploidy adjusted somatic copy number”) . This argument has been fully considered. After further consideration the rejection has been modified. The modified rejection states that the claims recite two types of abstract ideas that are identified in the Guidance. First the claims recite a mental process step. As explained above, the “detecting” step, as recited in claims 59 and 68, is a process that, under its broadest reasonable interpretation, covers performance of the limitation in the mind but for the recitation of a generic computer. That is, other than reciting “using a computer,” nothing in the claim precludes the determining step from practically being performed in the human mind. Secondly the claims recite mathematical concepts, namely mathematical relationships and calculations. Regarding Step 2A Prong Two, the Applicants argue that any alleged judicial exception is integrated into a practical application. They argue that the claims, as a whole, represent Applicant's discovery that “using a combined analysis of two or more types of CA Regions (including two or more types of Indicator CA regions)” can be used “to assess (e.g., detect, diagnose) HRD in a sample”. Such information can identify cancer patients that are likely to respond to a particular cancer treatment regimen. Applicants refer to a publication by Timms (Breast Cancer Research 2014 16:457) as evidence that it was unexpected that these specific components could be combined and achieve the improvement seen in HRD detection over the individual components. The Applicants refer to the PTAB decision in Ex parte Hannun and state that like in Ex parte Hannun, the present claims include specific features that were designed to achieve an improved technological result, thereby providing improvements to the technical field of cancer therapy. As such, the claims, as a whole, are not directed to the alleged abstract idea, but rather to a new and useful method that provides real, tangible benefits in the fields of cancer therapy and personalized medicine, thereby integrating any recited judicial exception into a specifically defined, practical application. This argument has been fully considered but is not persuasive. In Step 2A Prong 2 of the Guidance, we evaluate whether the claim as a whole integrates the recited judicial exception into a practical application of the exception. The Guidance species that this evaluation is conducted by first identifying whether there are any additional elements recited in the claim beyond the judicial exception, and then evaluating those additional elements individually and in combination to determine whether they integrate the exception into a practical application. If step (3) “detecting” is the judicial exception, then the additional elements recited in the claims are steps (1) “contacting” and (2) “sequencing”. These steps do not provide integration because they merely recite add insignificant extra-solution activity (data gathering) to the judicial exception. In response to the argument that the claims provide improvements to the technical field of cancer therapy, it is noted that “technology” used by the claim is targeted amplification and sequencing. The additional elements cited by the Applicants, do not improve the technology of targeted amplification and sequencing and do not improve any other technology. The additional elements, do not make the technology of targeted amplification and sequencing work better and do not make any other technology work better. Detecting the combination of LOH, TAI, and LST cannot provide integration of the method into a practical application because the detecting step is the judicial exception. Therefore, it is maintained that judicial exceptions are not integrated into a practical application and do not provide an inventive step. Claim Rejections - 35 USC § 103 5. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 68 is rejected under 35 U.S.C. 103 as being unpatentable over Silver (WO 2013/0130347 Pub 9/6/2013 and Filed 2/22/2013 with priority to 61/602,460 Filed 2/23/2012 and 61,604,810 Filed 2/29/2012) in view of Sulonen (Genome Biology 2011 12:R94) and Popova (Cancer Research 72(21); 5454-5462 Nov. 1, 2012). Regarding Claim 68 Silver teaches a method comprising determining a global chromosomal aberration score (GCAS), comprising obtaining a biological sample from the subject and determining whether a plurality of chromosomal regions displaying a chromosomal aberration exists within a plurality of chromosomal loci, wherein said chromosomal aberrations are allelic imbalance (AI) and loss of heterozygosity (LOH) relative to a control (para 0007). Silver teaches that the chromosomal loci are analyzed by next generation sequencing methods (para 0018, 0079). Silver teaches using a computer to analyze the sequence results (para 00211). Silver teaches that the biological sample comprises a cancer cell (para 0011). Silver teaches that cancer cell is from ovarian cancer, lung cancer, esophageal cancer (para 00157). Silver teaches the chromosomal regions being assayed are on at least two pairs of human chromosomes (para 00217 clms 29, 34). Silver defines a LOH region as a region of loss of heterozygosity that is longer than a first length but shorter than the length of the whole chromosome, wherein the first length is about 1.5 or more megabases (para 0029). Silver teaches that one type of AI that can be measured is telomeric imbalance. Silver defines a TAI region as a region of allelic imbalance that extends toward the telomere but does not cross the centromere, wherein the TAI region is 2 or more megabases (para 0081). Silver teaches that the GCAS is determined by adding together the number of individual chromosomal aberrations (para 0064). Silver teaches that a genome wide count of abnormal chromosomal regions in tumors can indicate the degree of DNA repair incompetence, independent of knowledge of any specific causative DNA repair detect (para 0094). Thus Silver teaches a method for detecting Indicator chromosomal aberration (CA) regions in at least one pair of chromosomes of a cancer cell from a sample from an ovarian, lung, or esophageal cancer patient comprising: sequencing, by a sequencer, human genomic DNA, thereby obtaining a genomic sequence comprising indicator CA regions; and detecting, using a computer, Indicator CA regions in the genomic sequence, wherein the Indicator CA regions comprise Indicator loss of heterozygosity (LOH) Regions and Indicator telomeric allelic imbalance (TAI) Regions. Silver does not teach a method wherein the sample is contacted with at least 500 oligonucleotide probes capable of hybridizing to human genomic DNA at a plurality of polymorphic regions prior to sequencing. However Sulonen is a review article that compares solution based exome capture methods for next generation sequencing. Sulonen compares kits sold by Agilent and NimbleGen. Sulonen teaches that Agilent SureSelect includes 346,500 and SureSelect 50MB 635,250 RNA probes (page 2, Table 1). Accordingly, it would have been obvious to one of ordinary skill in the art at the time the invention was made to have modified the method of Silver by first contacting the sample is contacted with at least 500 oligonucleotide probes capable of hybridizing to human genomic DNA at a plurality of polymorphic regions prior to sequencing as suggested by Sulonen. The skilled artisan would have been motivated to capture exome sequences prior to sequencing since this is more cost effective and faster than sequencing the entire genome. The combined references do not teach a method further comprising detection an Indicator LSTs, wherein an Indicator LST is a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length. However Popova teaches the detection of LST regions (abstract). Popova defines a LST as a chromosomal break between adjacent regions of at least 10 MB, the number of LSTs in the tumor genome was estimated for each chromosome arm independently (not accounting for the centromeric breaks) and after filtering and smoothing of all variations less than 3 Mb (page 5457). Popova teaches that a high number of LSTs is a marker of homologous recombination pathway deficiency and surrogate measure of genomic instability (page 5460, left col). Accordingly, it would have been obvious to one of ordinary skill in the art at the time the invention was made to have modified the method of Silver and Sulonen by further analyzing the sequencing results for the presence of LST regions as suggested by Popova. In the instant case Silver teaches that a genome wide count of abnormal chromosomal regions (LOH regions and TAI regions) in tumors can indicate the degree of DNA repair incompetence, independent of knowledge of any specific causative DNA repair detect (para 0094). Additionally Popova teaches that a high number of LSTs is a marker of homologous recombination pathway deficiency and surrogate measure of genomic instability (page 5460, left col). It is noted that homologous recombination is a mechanism for DNA repair. Thus it would have been obvious to an ordinary artisan to have further considered the number of Indicator LST regions in addition to LOH regions and TAI regions for the benefit of including an additional type of chromosomal aberration known to be indicative of the degree of DNA repair incompetence in a cancer cell. Double Patenting 8. The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. 9. Claim 68 is provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 37-64 of US Application 19/088496 in view of Sulonen (Genome Biology 2011 12:R94). Although the claims at issue are not identical, they are not patentably distinct from each other. Regarding Claim 68 both sets of claims are drawn to a method of detecting chromosomal aberration (CA) regions in at least one pair of human chromosomes of a cancer cell from a sample from a ovarian or esophageal cancer patient (see clm 51, 52, 61 of the copending application). Both sets of claims require sequencing the human genomic DNA, and detecting in the sequencing results loss of heterozygosity (LOH) regions, telomeric allelic imbalance (TAI) regions, and large scale transitions (LSTs) (see clm 51 of the copending application). Both sets of claims state that a LOH Region is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located (see clm 51 of the copending application). Both sets of claims state that an TAI Region is a region with allelic imbalance that (i) extends to one of the subtelomeres, and (iii) is longer than 1.5 megabases (see clm 51 of the copending application). Both sets of claims state that an LST region is a region comprising a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length (see clm 51 of the copending application). The instant claim is different from the copending ones because it requires contacting the sample with at least 500 oligonucleotide probes capable of hybridizing to human genomic DNA at a plurality of polymorphic regions prior to the sequencing step. However, Sulonen teaches this limitation (see 103 rejection above). It would have been obvious to modify the method of the copending application in view of Sulonen for the same reasons discussed in the 103 rejection. 10. Claim 68 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-6 of US Patent 10,400,278 in view of Silver (WO 2013/0130347 Pub 9/6/2013 and Filed 2/22/2013 with priority to 61/602,460 Filed 2/23/2012 and 61,604,810 Filed 2/29/2012) in view of Sulonen (Genome Biology 2011 12:R94). Although the claims at issue are not identical, they are not patentably distinct from each other. Regarding Claim 68 both sets of claims are drawn to a method of detecting chromosomal aberration (CA) regions in at least one pair of human chromosomes of a cancer cell from a sample from a patient (see clm 1 of the Patent). Both sets of claims require detecting DNA comprising loss of heterozygosity (LOH) regions, telomeric allelic imbalance (TAI) regions, and large scale transitions (LSTs) (see clm 1 of the Patent). Both sets of claims state that a LOH Region is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located (see clm 1 of the Patent). Both sets of claims state that an TAI Region is a region with allelic imbalance that (i) extends to one of the subtelomeres, and (iii) is longer than 1.5 megabases (see clm 1 of the Patent). Both sets of claims state that an LST region is a region comprising a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length (see clm 1 of the Patent). The instant claim is different from the claims of the patent because it requires contacting the sample with at least 500 probes capable of hybridizing to the human and sequencing the human genomic DNA. Further the instant claims are different because they state that the cancer is ovarian or esophageal cancer. However Silver and Sulonen have been relied upon to teach these limitations (see 103 rejections above). It would have been obvious to modify the Patent by performing exome capture followed by sequencing to detect the regions since this method was known in the art at the time of the invention. 11. Claim 68 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-18 of US Patent 12,221,656 in view of Silver (WO 2013/0130347 Pub 9/6/2013 and Filed 2/22/2013 with priority to 61/602,460 Filed 2/23/2012 and 61,604,810 Filed 2/29/2012) and Popova (Cancer Research 72(21); 5454-5462 Nov. 1, 2012). Although the claims at issue are not identical, they are not patentably distinct from each other. Regarding Claim 68 both sets of claims are drawn to a method of detecting chromosomal aberration (CA) regions in at least one pair of human chromosomes of a cancer cell from a sample from a ovarian or esophageal cancer patient (see clm 2 and 3 of the Patent). Both sets of claims require contacting the sample with at least 500 oligonucleotide probes capable of hybridizing to a plurality of polymorphic regions (see clm 1 of the Patent). Both sets of claims require detecting DNA comprising loss of heterozygosity (LOH) regions, and large scale transitions (LSTs) (see clm 1 of the Patent). Both sets of claims state that a LOH Region is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located (see clm 1 of the Patent). Both sets of claims state that an LST region is a region comprising a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length (see clm 1 of the Patent). The instant claim is different from the claims of the patent because it requires sequencing, by a sequencer the human genomic DNA. However Silver teaches sequencing to detect LOH and LST regions. It would have been obvious to modify the Patent by suing sequencing since this method was known in the art for detecting polymorphisms. The instant claim is different from the Patent because it further requires including the number of indicator TAI regions, wherein a TAI Region is a TAI Region with allelic imbalance that (a) extends to one of the sub telomeres, (b) does not cross the centromere and (c) is longer than 1.5 megabases. However Silver teaches a method for predicting the outcome of anti-cancer treatment of a subject with a cell hyper proliferative disorder, comprising determining a global chromosomal aberration score (GCAS), comprising obtaining a biological sample from the subject and determining whether a plurality of chromosomal regions displaying a chromosomal aberration exists within a plurality of chromosomal loci, wherein said chromosomal aberrations are allelic imbalance (AI) and loss of heterozygosity (LOH) relative to a control, wherein the presence of a chromosomal regions displaying said chromosomal aberrations predicts the outcome of anti-cancer treatment of the subject (para 0007). Silver teaches that one type of AI that can be measured is telomeric imbalance. Silver defines a TAI region as a region of allelic imbalance that extends toward the telomere but does not cross the centromere, wherein the TAI region is 11 or more megabases (para 0081). Accordingly, it would have been obvious to have modified the method of the Patent by further considering the number of TAI regions for the benefit of including an additional type of chromosomal aberration that is predictive of the outcome of anti-cancer treatment of a patient. 12. Claim 68 is rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-10 of US Patent 12,421,555 in view of Silver (WO 2013/0130347 Pub 9/6/2013 and Filed 2/22/2013 with priority to 61/602,460 Filed 2/23/2012 and 61,604,810 Filed 2/29/2012).

It would have been obvious to modify the Patent by suing sequencing since this method was known in the art for detecting polymorphisms. 13. Claim 68 is provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 37-56 of US Application 19/048,611 in view of Sulonen (Genome Biology 2011 12:R94). Although the claims at issue are not identical, they are not patentably distinct from each other. Regarding Claim 68 both sets of claims are drawn to a method of detecting chromosomal aberration (CA) regions in at least one pair of human chromosomes of a cancer cell from a sample from a ovarian or esophageal cancer patient (see clm 37, 38 of the copending application). Both sets of claims require sequencing the human genomic DNA, and detecting in the sequencing results loss of heterozygosity (LOH) regions, telomeric allelic imbalance (TAI) regions, and large scale transitions (LSTs) (see clm 37 of the copending application). Both sets of claims state that a LOH Region is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located (see clm 37 of the copending application). Both sets of claims state that an TAI Region is a region with allelic imbalance that (i) extends to one of the subtelomeres, and (iii) is longer than 1.5 megabases (see clm 37 of the copending application). Both sets of claims state that an LST region is a region comprising a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length (see clm 37 of the copending application). The instant claim is different from the copending ones because it requires contacting the sample with at least 500 oligonucleotide probes capable of hybridizing to human genomic DNA at a plurality of polymorphic regions prior to the sequencing step. However, Sulonen teaches this limitation (see 103 rejection above). It would have been obvious to modify the method of the copending application in view of Sulonen for the same reasons discussed in the 103 rejection. 14. Claim 68 is provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 74-76, 78-80, 83-87, 91-92, and 95 of US Application 18/076,279 in view of Sulonen (Genome Biology 2011 12:R94. Although the claims at issue are not identical, they are not patentably distinct from each other. Regarding Claim 68 both sets of claims are drawn to a method of detecting chromosomal aberration (CA) regions in at least one pair of human chromosomes of a cancer cell from a sample from a cancer patient (see clm 74 of the copending application). Both sets of claims require sequencing the human genomic DNA, and detecting in the sequencing results loss of heterozygosity (LOH) regions, telomeric allelic imbalance (TAI) regions, and large scale transitions (LSTs) (see clm 74 of the copending application). Both sets of claims state that a LOH Region is longer than 1.5 megabases but shorter than the entire length of the respective chromosome within which the LOH Region is located (see clm 75 of the copending application). Both sets of claims state that an TAI Region is a region with allelic imbalance that (i) extends to one of the subtelomeres, and (iii) is longer than 1.5 megabases (see clm 78 of the copending application). Both sets of claims state that an LST region is a region comprising a somatic copy number breakpoint along the length of a chromosome that is between two regions of at least 6 megabases in length (see clm 80 of the copending application). The instant claim is different from the copending ones because it requires contacting the sample with at least 500 oligonucleotide probes capable of hybridizing to human genomic DNA at a plurality of polymorphic regions prior to the sequencing step. However, Sulonen teaches this limitation (see 103 rejection above). It would have been obvious to modify the method of the copending application in view of Sulonen for the same reasons discussed in the 103 rejection. 15.
