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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-3, 11, 12, 15, 16, 19, 20, 23, 34, 36, 63-67, and 69 are rejected under 35 U.S.C. 103 as being unpatentable over Xue et al (US20230051793A1), as evidenced by Addgene #12251, 12253, and 12259 and in view of Bisgrove et al (US9127283B2). The teachings of Xue et al and Addgene are set forth above. Xue et al, evidenced by Addgene, anticipates claims 1-3, 11, 12, 15, 16, 19, 20, 23, 34, 36, 63, 64, and 67. Regarding claims 65 and 66: Following the discussion of claim 1 above, Xue et al discloses a producer cell comprising Gag/Pol, Rev and VSV-G under the control of inducible promoters. The inducible promoter can comprise a Tet-off expression system. Table 3 of Xue et al discloses a Gag/Pol having a sequence identical to the Gag sequences of Gag/Pol from Addgene #12251, a VSV-G sequence identical to the VSV-G sequence of Addgene #12259, and a Rev sequence identical to the Rev sequence of Addgene #12253. The Gag sequence from Addgene #12251 has 96.8% similarity to SEQ ID NO: 17 of the instant application (reads on at least 80%) and the Pol sequence from Addgene #12251 has 100% similarity to SEQ ID NO: 18 of the instant application. The VSV-G sequence of Addgene #12259 has 100% similarity to SEQ ID NO: 19 of the instant application. The Rev sequence of Addgene #12253 has 100% similarity to SEQ ID NO: 20 of the instant application. See Sequence Alignments at end of office action. Furthermore, Xue discloses one or more of the Gag, Pol, Rev, and VSV-G sequences is under control of an inducible system thus, in some embodiments all of Gag, Pol, VSV-G, and Rev are operably linked to a promoter capable of being activated by the Tet-Off protein. Xue et al does not disclose a sequence for the promoter of a Tet-Off system. Bisgrove discloses a Tet-Off promoter having SEQ ID NO: 16 which has 100% similarity to SEQ ID NO: 11 of the instant application. See alignment at end of office action. Given that Xue et al discloses a producer cell comprising Gag/Pol, Rev, and VSV-G under control of a Tet-Off system and Bisgrove discloses a promoter having SEQ ID NO: 16 for a Tet-Off system, it would have been prima facie obvious to substitute the Tet-Off system of Xue et al with the Tet-Off system of Bisgrove, having a promoter with SEQ ID NO: 16, in the cell of Xue et al. One would have expected the Tet-Off system of Bisgrove to work equivocally with the Tet-Off system of Xue et al in the cell of Xue et al because both systems are Tet-Off systems. Substitution of one element for another known in the field, wherein the result of the substitution would have been predictable is considered to be obvious. See KSR International Co. V Teleflex Inc 82 USPQ2d 1385 (US2007) at page 1395. Regarding claim 69: Following the discussion of claim 1 above, Xue et al discloses a producer cell comprising Gag/Pol, Rev and VSV-G under the control of an inducible system which can comprise a Tet-Off System. It would have been prima facie obvious to substitute the Tet-Off system of Xue et al with the Tet-Off System of Bisgrove (See rejection of claim 65 above). Additionally, Xue et al discloses examples in which plasmids are transiently transfected (reads on not stably integrated) into the cells in order to optimize the virus producing packaging cells (See Example 6). Given that Xue et al discloses transiently transfecting cells in order to optimize the virus producing cells, it would have been prima facie obvious to a person or ordinary skill in the art to transiently transfect Plasmids comprising a Tet-Off protein into the producer cells of Xue et al. One would have been motivated to transiently transfect the plasmid into the cells of Xue et al in order to optimize conditions for the cells. There is a reasonable expectation of success because Xue et al teaches examples in which conditions are optimized using transient transfections. Claims 1-3, 11, 12, 15, 16, 19, 20, 23, 25, 26, 28, 29, 31, 32, 34, 36, and 63-70 are rejected under 35 U.S.C. 103 as being unpatentable over Xue et al (US20230051793A1), as evidenced by Addgene #12251, 12253, and 12259 and in view of Bisgrove et al (US9127283B2) and Shin et al (US20210062220A1). The teachings of Xue et al, Addgene, Bisgrove et al, and Shin et al are set forth above. Xue et al, evidenced by Addgene, anticipates claims 1-3, 11, 12, 15, 16, 19, 20, 23, 34, 36, 63, 64, and 67. Xue et al in view of Bisgrove render claims 1-3, 11, 12, 15, 16, 19, 20, 23, 34, 36, 63-67, and 69 obvious. Regarding claims 25 and 29 : Following the discussion of claim 1 above, Xue et al discloses a producer cell comprising Gag/Pol, Rev and VSV-G under the control of an inducible system. The system of Xue et al comprises a first stably integrated polynucleic acid comprising sequences encoding for Gag and Pol. Xue et al does not disclose a single polynucleic acid comprising the sequences of VSV-G and Rev. Shin et al discloses a polynucleic acid that can be stably integrated into a lentiviral producer cell. The polynucleic acid of Shin et al comprises a REV gene under a first promoter, a VSV-G gene under control of a second promoter, and a GAG gene and POL gene under control of a third promoter. Shin et al further teaches lentiviral production systems utilizing four separate plasmids are labor-intensive (See ¶0004-0009). Given that Xue et al discloses plasmids for stably integrating Gag/Pol, Rev, and VSV-G into cells for lentiviral production under the control of an inducible promoter system and Shin et al teaches Gag/Pol, Rev, and VSV-G can be combined into the same polynucleotide, it would have been prima facie obvious to a person of ordinary skill in the art to modify the plasmids of Xue et al by including expression cassettes comprising any of Gag/Pol, Rev, and/or VSV-G in the same plasmid in the method of Xue et al in order to simplify integration of the polynucleotide into the producer cell. One would have been motivated to modify the plasmids of Xue et al to comprise any of Gag/Pol, Rev, and/or VSV-G in a single plasmid because Shin et al teaches using separate plasmids is labor-intensive. There is a reasonable expectation of success because Shin et al teaches Gag/Pol, Rev, and VSV-G can be combined into a single plasmid while each is still under the control of its own inducible promoter. Regarding claim 26: Following the discussion of claims 1 and 25 above, Xue et al discloses a plasmid comprising Gag-Pol under control of a Tet-On and/or Cumate inducible expression system which reads on a first expression cassette comprising a nucleic acid sequence of a first chemically inducible promoter; and a nucleic acid sequence encoding for a polycistronic RNA comprising Gag and Pol. Regarding claim 28: Following the discussion of claims 1, 25, and 26 above, Xue et al discloses the plasmid comprising Gag and Pol can further comprise a screening gene sequence under control of an SV40 promoter which reads on a selection marker operably linked to a promoter Regarding claim 31: Following the discussion of claims 1 and 25 above, Xue et al discloses any of the plasmids can further comprise a screening gene sequence under control of an SV40 promoter which reads on a selection marker operably linked to a promoter. Regarding claim 32: Following the discussion of claims 1 and 25 above, Xue discloses the cells comprise a Tet-On system comprising TRE3G or TREadv response elements and rtRAadv and rtTA3G transactivators under the control of a CAGGS promoter (See Fig. 1). rtRAadv and rtTA3G read on transcriptional activators that when expressed in the presence of a small molecule inducer, bind to a chemically inducible promoter of the engineered cell. Regarding claims 68 and 70: Following the discussion of claims 1, 36, and 65 above, Xue et al discloses a producer cell comprising Gag/Pol, Rev and VSV-G under the control of an inducible system which can comprise a Tet-Off System. It would have been prima facie obvious to substitute the Tet-Off system of Xue et al with the Tet-Off System of Bisgrove (See rejection of claim 65 above). Xue et al further discloses introducing a nucleic acid comprising a gene of interest (e.g. BDDF8cHA) into the producer cell. The exemplary plasmid comprising BDDF8cHA in Fig. 1 of Xue further comprises a 5’ LTR and a 3’LTR. Additionally, Xue et al discloses examples in which plasmids are transiently transfected (reads on not stably integrated) into the cells in order to optimize the virus producing packaging cells (See Example 6). Given that Xue et al discloses transiently transfecting cells in order to optimize the virus producing cells, it would have been prima facie obvious to a person or ordinary skill in the art to transiently transfect Plasmids comprising a Tet-Off protein and the BDDF8cHA protein which further comprises 5’ and 3’ LTR sequences into the producer cells of Xue et al. One would have been motivated to transiently transfect the plasmids into the cells of Xue et al in order to optimize conditions for the cells. There is a reasonable expectation of success because Xue et al teaches examples in which conditions are optimized using transient transfections. Xue et al does not disclose a single polynucleic acid comprising a Tet-Off protein and a gene of interest. Shin et al teaches combining multiple components required for lentiviral production onto the same plasmid. Shin et al further teaches lentiviral production systems utilizing four separate plasmids are labor-intensive (See ¶0004-0009). Given that Xue et al discloses plasmids for lentiviral producer cells and Shin et al teaches multiple components for lentiviral production can be combined onto the same plasmid, it would have been prima facie obvious to modify the expression cassettes comprising a Tet-Off protein so that it further comprises a gene of interest along which further comprises a 5’ and 3’ LTR in the method of Xue et al in order to simplify integration of the polynucleotide into the producer cell. One would have been motivated to express both the Tet-Off protein and gene of interest from a single plasmid because Shin et al teaches using separate plasmids is labor-intensive. There is a reasonable expectation of success because Shin et al teaches components for lentiviral producer cells can be combined into the same plasmid.
