Office Action

§101 §103 §112
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) submitted on May 15, 2023 has been considered by the examiner. The Foreign patent document by MedCaptain Medical Technology Co. is not filed in English and therefore has not been considered by the examiner. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION. —The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 15 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The term “substantially ” in claim 15 line 19 is a relative term which renders the claim indefinite. The term “substantially” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. As recited by the instant claim: "substantially identical to the target sequence". How much of the synthetic nucleotide sequence is considered identical to the target sequence? . Claim Rejections - 35 USC § 101 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 1-10 and 15-20 rejected under 35 U.S.C. 101 because the claimed invention is directed to a natural phenomenon (including a product of nature) without significantly more. Subject Matter Eligibility Test (see MPEP § 2106): Step 1: Are the claims to a process, machine, manufacture, or composition of matter? Yes. The claims are directed towards a composition of matter (kit) comprising nucleic acids Step 2A: Are the claims directed to a judicial exception? Prong 1: Do the claims recite an abstract idea, law of nature, or natural phenomenon? As discussed in MPEP 2106.04(II)(A)(1), the meaning of “recites” is “set forth” or “describes”. That is, a claim recites a judicial exception when the judicial exception is “set forth” or “described” in the claim. In the instant case, the claims describe a natural phenomenon (Naturally occurring primer set sequences). Claims 1 and 2 recite a nucleic acid screening kit comprising inner and outer, forward and backward primer sets selected from 56 different sequences. The kits of claims 3, 4, 9, and 10 are comprised solely of the aforementioned primer sets, with claims 3 and 4 comprising 13 different additional sequences of a Loop F primer. When searched, the primers showed 100% concordance with naturally occurring sequences derived from the homo sapiens genome. A selection of some of the sequence search results is shown below.

As discussed in MPEP 2106.04(II)(A)(2), “Because a judicial exception is not eligible subject matter, Bilski, 561 U.S. at 601, 95 USPQ2d at 1005-06 (quoting Chakrabarty, 447 U.S. at 309, 206 USPQ at 197 (1980)), if there are no additional claim elements besides the judicial exception, or if the additional claim elements merely recite another judicial exception, that is insufficient to integrate the judicial exception into a practical application. See, e.g., RecogniCorp, LLC v. Nintendo Co., 855 F.3d 1322, 1327, 122 USPQ2d 1377 (Fed. Cir. 2017) ("Adding one abstract idea (math) to another abstract idea (encoding and decoding) does not render the claim non-abstract"); Genetic Techs. v. Merial LLC, 818 F.3d 1369, 1376, 118 USPQ2d 1541, 1546 (Fed. Cir. 2016) (eligibility "cannot be furnished by the unpatentable law of nature (or natural phenomenon or abstract idea) itself."). For a claim reciting a judicial exception to be eligible, the additional elements (if any) in the claim must "transform the nature of the claim" into a patent-eligible application of the judicial exception, Alice Corp., 573 U.S. at 217, 110 USPQ2d at 1981, either at Prong Two or in Step 2B.” The considerations to be used are set forth at MPEP 2106.05(a) through (c) and (e) through (h). Simply placing primer sets into a kit does not meaningfully change the primer set itself and is considered insignificant extra-solution activity because there is no structural change to the primers. The term "extra-solution activity" can be understood as activities incidental to the primary process or product that are merely a nominal or tangential addition to the claim. As explained by the Supreme Court, the addition of insignificant extra-solution activity does not amount to an inventive concept, particularly when the activity is well-understood or conventional. Parker v. Flook, 437 U.S. 584, 588-89, 198 USPQ 193, 196 (1978). See MPEP § 2106.05(g). There are no additional elements in claims 1-4,9, and 10; therefore, the judicial exception is not integrated into a practical application. Step 2B: Do the claims recite additional elements that amount to significantly more than the judicial exception? Claims 5-8 and 15-20 provide additional elements (e.g. enzymes, reagents, test tubes) that do not amount to significantly more than the judicial exception; therefore, the judicial exception is not integrated into a practical application, meaning these claims do not contain eligible subject matter. Claim Rejections - 35 USC § 103 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, 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(s) 1-8, 11-13 ,15-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dipanjan et. al. (US20210388454A1, published 12/16/21) as evidenced by New England Biolabs (New England Biolab, WarmStart Colorimetric LAMP 2X Master Mix (DNA & RNA), Date Accessed: 3/18/26) Dipanjan teaches a nanotechnology-based sensing system to detect biological pathogens and the use of RT-LAMP method to target N gene sequence of COVID-19 causative virus, SARS-CoV-2. For the RT-LAMP method, Dipanjan teaches a primer set consisting of six primers in which the forward and backward inner and outer primers are the same as the forward and backward inner and outer primers of the instant application (Table 2). SEQ ID NOs: 60,61, 62, and 63 of the instant application exhibit a 100% identical match with SEQ ID NOs: 10, 11, 12, and 13 of the reference respectively can be shown in Table 2 and the chart below for exemplarily comparison purposes ([0096], instant Claims 1, 2, 11, 12 ,15, 17, 19, 20).

An example of NAA protocol, Dipanjan teaches that 8 μL aliquots of the NAA reaction mixture from Table 3 were prepared and added to 2 μL of collected sample (sample can be either extracted RNA or direct sample treated with lysis buffer or artificial saliva sample spiked with clinical samples' RNA) in PCR strip tubes or PCR plates. Samples were mixed well by pipetting up and down for few times. Water was used as a negative control ([0099], instant claims 5,7, 11, 15). The examiner is interpreting the usage of PCR strip tubes and the NAA primer mixture of the reference as capable of carrying out the limitations of instant claims 15, 16, 18, and 19 in which singular or multiple tubes contain the negative control, positive control, first and/or second reaction. As evidenced by New England Biolabs, the WarmStart LAMP 2X Master Mix of the reference is offered with dUTP and contains a visible pH indicator for rapid and easy detection of Loop-Mediated Isothermal Amplification (LAMP) and RT-LAMP reactions, teaching the limitations of instant claims 8, 15,17,19, and 20 (New England Biolabs, pg.1). Dipanjan teaches that kits may include a sample collection apparatus such as a swab or collection vial, a sample collection and/or storage and/or preservation buffer or solution, lysis buffer or detergent, components and reagents for nucleic acid extraction, components and reagents for nucleic acid amplification, and/or a detection apparatus ([0067], instant claim 6). Dipanjan teaches usage of a forward loop primer sequence SEQ ID NO 14, that is equivalent to SEQ ID NO 64 of the instant application (instant claims 3, 4, 13, 16 and 18). However, the sequence of the instant application contains one additional “g” residue at the end in comparison to the reference sequence, as can be observed below in Table 2 and the sequence alignments for comparative purposes. It would have been obvious to one of ordinary skill before the effective filing date of the claimed invention to have altered the sequence of the forward loop primer by adding an additional nucleotide in order to optimize the primer to produce characteristics such as increased binding annealing, specificity, and acceleration of amplification of the primer to the target sequence.
