Double Patenting Rejection 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. See 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); and 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) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent is shown to be commonly owned with this application. See 37 CFR 1.130(b). Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). The instant Claims are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1-27 of US PAT11899014. An obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but an examined application claim not is patentably distinct from the reference claim(s) because the examined 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). Although the conflicting claims are not identical, they are not patentably distinct from each other. The claims 1-27 of US PAT11899014 are directed to sensor fungal cell comprising a fungal non-native G-protein coupled receptor (GPCR) that binds to a peptide analyte derived from an agent, wherein the wherein the non-native fungal GPCR is a GPCR comprising an amino acid sequence selected from the group consisting of SEQ ID NOs: 6, 9, 12, 15, 18, 21, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, 110, 112 and 222. The Instant claims also are directed to genetically-engineered cell expressing: (a) at least one heterologous G-protein coupled receptor (GPCR), wherein the amino acid sequence of the heterologous GPCR is at least about 95% homologous to an amino acid sequence comprising any one of SEQ ID NOs: 117-161 or an amino acid sequence provided in Table 11 and/or is encoded by a nucleotide sequence that is at least about 95% homologous to a nucleotide sequence comprising any one of SEQ ID NOs: 168-211; and/or and (b) at least one heterologous secretable GPCR peptide ligand, wherein the amino acid sequence of the heterologous GPCR peptide ligand is at least about 95% homologous to an amino acid sequence comprising any one of SEQ ID NOs: 1-116 or an amino acid sequence provided in Table 12 and/or encoded by a nucleotide sequence that is about 95% homologous to a nucleotide sequence comprising any one of SEQ ID NOs: 215-230. The specification that teach genetically-engineered cell expressing heterologous G-protein coupled receptor (GPCR), wherein the amino acid sequence of the heterologous GPCR as disclosed in claim 6 of patent can also teach in different embodiment the genetically-engineered cell expressing heterologous G-protein coupled receptor (GPCR), wherein the amino acid sequence of the heterologous GPCR in the instant claims of the instant application. It would have been obvious to one of ordinary skill in the art to select this specific embodiment of the genera of cell expressing said GPCR that practiced for the claims of that patent to that of instant claims. Therefore claims 1-8,10-17 and 21-23 of instant application are obvious over claims 1-27 US PAT 11899014. The instant Claims are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1-32 of US PAT 10725036. An obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but an examined application claim not is patentably distinct from the reference claim(s) because the examined 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). Although the conflicting claims are not identical, they are not patentably distinct from each other. The claims 1-32 of US PAT 10725036 are directed to method of use of sensor fungal cell comprising a fungal non-native G-protein coupled receptor (GPCR) that binds to a peptide analyte derived from an agent, wherein the wherein the non-native fungal GPCR is a GPCR comprising an amino acid sequence selected from the group consisting of SEQ ID NOs: 6, 9, 12, 15, 18, 21, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, 110, 112 and 222. The Instant claims also are directed to genetically-engineered cell expressing: (a) at least one heterologous G-protein coupled receptor (GPCR), wherein the amino acid sequence of the heterologous GPCR is at least about 95% homologous to an amino acid sequence comprising any one of SEQ ID NOs: 117-161 or an amino acid sequence provided in Table 11 and/or is encoded by a nucleotide sequence that is at least about 95% homologous to a nucleotide sequence comprising any one of SEQ ID NOs: 168-211; and/or and (b) at least one heterologous secretable GPCR peptide ligand, wherein the amino acid sequence of the heterologous GPCR peptide ligand is at least about 95% homologous to an amino acid sequence comprising any one of SEQ ID NOs: 1-116 or an amino acid sequence provided in Table 12 and/or encoded by a nucleotide sequence that is about 95% homologous to a nucleotide sequence comprising any one of SEQ ID NOs: 215-230. The specification that teach genetically-engineered cell expressing heterologous G-protein coupled receptor (GPCR), wherein the amino acid sequence of the heterologous GPCR as disclosed in claim 6 of patent can also teach in different embodiment the genetically-engineered cell expressing heterologous G-protein coupled receptor (GPCR), wherein the amino acid sequence of the heterologous GPCR in the instant claims of the instant application. It would have been obvious to one of ordinary skill in the art to select this specific embodiment of the genera of cell expressing said GPCR that practiced for the claims of that patent to that of instant claims. Therefore claims 1-8,10-17 and 21-23 of instant application are obvious over claims 1-32 of US PAT 10725036. TD submission would overcome the above ODP rejections. Until TD submitted or claims substantially amended as discussed during the Interview ODP rejection remained. Conclusion Claims 1-8,10-17 and 21-23 are rejected. No claim is allowed.
