DETAILED ACTION
Status of the Claims
Claims 1-20 are pending and the subject of this NON-FINAL Office Action.
Large IDSs With Multiple Irrelevant References/No IDS Fee
The IDS filed 08/13/2025, which has over 400 references, has not been considered because it was not filed with a proper IDS size fee. See 37 § C.F.R. 1.17(v); https://www.uspto.gov/sites/default/files/documents/quick-reference-guide-to-the-information-disclosure-statement-ids.pdf.
Applicants filed 80 pages of IDS with over 1,000 listed references. First, it is impossible to search in detail through all 1,000-plus references in any reasonable amount of time. Second, this is not the first application in this family of applications; in fact, there are over 100 others. Applicants have had ample opportunity to winnow their IDS down to only claim-relevant references. Furthermore, after a random skim of the references in the IDS 01/17/2025 within the incredibly limited time allotted to the Examiner, the Examiner determines that many of the references are irrelevant to the claimed subject matter, having nothing to do with the allele-frequency system claimed. Which leads to the larger problem: which references are relevant, and why were these seemingly irrelevant references filed? Before filing an IDS, Applicants have a duty to examine the references themselves and determine which references are reasonably pertinent to the claimed invention. If any particular preference(s) is/are directly pertinent to the claimed invention, then Applicants are encouraged to point this out in the form of a new IDS.
Priority
The claims receive a priority date of 05/18/2011 because the non-provisional application (13/300235) filed on that date is the first priority document to disclose a single system comprising a sequencer and a computer processer programmed to receive the sequencing reads, quantify the sequencing reads corresponding to each allele at the polymorphic loci, and measure the amount of DNA from the first individual in the biological sample of the second individual based on allele frequencies at a plurality of the polymorphic loci.
Claim interpretations
Claim 1 is directed to a system (i.e. product) with the following generic structure:
A sequencer; and
computer processer programmed to receive sequencing reads, quantify the sequencing reads corresponding to any alleles at any polymorphic loci, and measure the amount of DNA based on allele frequencies at a plurality of the polymorphic loci.
All other claims merely recite intended uses of the system; thus, they fail to distinguish the system over the prior art.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. § 102 that form the basis for the rejections under this section made in this Office action:
(A) A person shall be entitled to a patent unless –
(1)the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention; or
(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-20 are rejected under 35 U.S.C. § 102(a)(1) as being anticipated by DHALLAN (US 7,332,277).
As to claim 1, DHALLAN teaches a system comprising a sequencer (cols. 63-65, describing sequencing analysis using sequencer); and computer processer programmed to receive sequencing reads, quantify the sequencing reads corresponding to any alleles at any polymorphic loci, and measure the amount of DNA based on allele frequencies at a plurality of the polymorphic loci (GeneScan or ImageQuant programming; col. 65, l. 29 – col. 66, l. 20). Specifically, DHALLAN teaches
In one embodiment, the ratio of alleles at a heterozygous locus of interest can be calculated. The intensity of a nucleotide at the loci of interest can be quantified using any number of computer programs including but not limited to GeneScan and ImageQuant. For example, for a heterozygous SNP, there are two nucleotides, and each should be present in a 1:1 ratio. In a preferred embodiment, the ratio of multiple heterozygous SNPs can be calculated.
In one embodiment, the ratio for a variable nucleotide at alleles at a heterozygous locus of interest can be calculated. The intensity of each variable nucleotide present at the loci of interest can be quantified using any number of computer programs including but not limited to GeneScan and ImageQuant. For example, for a heterozygous SNP, there will be two nucleotides present, and each may be present in a 1:1 ratio. In a preferred embodiment, the ratio of multiple heterozygous SNPs can be calculated
(col. 65, ll. 30-47).
Claims 1-20 are rejected under 35 U.S.C. § 102(a)(2) as being anticipated by RAVA (US 2012/0010085).
As to claim 1, RAVA teaches a system comprising a sequencer (para. 0189); and computer processer programmed to receive sequencing reads, quantify the sequencing reads corresponding to any alleles at any polymorphic loci, and measure the amount of DNA based on allele frequencies at a plurality of the polymorphic loci (para. 0190). Specifically, RAVA teaches
c. Analysis of Sequencing Data for the Determination of Fetal Fraction
Upon completion of sequencing of the sample, the Illumina “Sequencer Control Software” transferred image and base call files to a Unix server running the Illumina “Genome Analyzer Pipeline” software version 1.51. the 36 bp reads were aligned to an artificial reference genome e.g. a SNP genome, using the BOWTIE program. The artificial reference genome was identified as the grouping of the polymorphic DNA sequences that encompass the alleles comprised in the polymorphic target sequences. For example, the artificial reference genome is a SNP genome comprising SEQ ID NOs: 1-56. Only reads that mapped uniquely to the artificial genome were used for the analysis of fetal fraction. Reads that matched perfectly to the SNP genome were counted as tags and filtered. Of the remaining reads, only reads having one or two mismatches were counted as tags and included in the analysis. Tags mapped to each of the polymorphic alleles were counted, and the fetal fraction was determined as a percent of the ratio of the number of tags mapped to the major allele i.e. maternal allele, and the number of tags mapped to the minor allele i.e. fetal allele.
