Office Action

§DP
ATTACHMEN T TO NOTICE OF ALLOWANCE The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 1) A request for continued examination under 37 C.F.R 1.114, including the fee set forth in 37 C.F.R 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 C.F.R 1.114, and the fee set forth in 37 C.F.R 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 C.F.R 1.114.

(Environ. Sci. Pollut. Res. 27: 36203-36214, 18 June 2020, of record) is moot in light of Applicant’s cancellation of the claims. 9) The rejection of claims 1, 8 and 11 set forth in paragraph 21 of the Office Action mailed 04/02/25 under 35 U.S.C § 102(a)(1) as being anticipated by Lee et al. (Biotechnol. Bioeng. 43: 1146-1152, 1994, of record) is moot in light of Applicant’s cancellation of the claims. 10) The rejection of claims 6, 15, 17 and 31 set forth in paragraph 23 of the Office Action mailed 04/02/25 under 35 U.S.C § 103 as being unpatentable over Lee et al. (Biotechnol. Bioeng. 43: 1146-1152, 1994, of record) as applied to claim 1 above and further in view of Sriprapat et al. (Water Air Soil Pollut. 224: 1482, pages 1-9, 2013, of record) (Sriprapat et al., 2013) and Dela Cruz et al. (Environ. Sci. Pollution Res.

(Environ. Sci. Pollut. Res. 27: 36203-36214, 18 June 2020, of record) as applied to claim 1 above and further in view of Sriprapat et al. (Water Air Soil Pollut. 224: 1482, pages 1-9, 2013) (Sriprapat et al., 2013) and Dela Cruz et al. (Environ. Sci. Pollution Res. Springer-Verlag, Berlin, 21: 13909-13928, 2014, of record) is moot in light of Applicant’s cancellation of the claims. Double Patenting Rejection 12) 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 claims at issue 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); 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) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the reference application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO internet Web site contains terminal disclaimer forms which may be used. Please visit http://www.uspto.gov/forms/. The filing date of the application will determine what form 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 http://www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. 13) Claims 47-54 are provisionally rejected under the judicially created doctrine of non-statutory obviousness-type double patenting as being unpatentable over claims 89-91 of the co-pending 18284959 (‘959) application. Although the conflicting claims are not identical, they are not patentably distinct from each other. The above-identified claims of the co-pending ‘959 application are drawn to a system comprising a composition comprising engineered Pseudomonas putida and Methylobacterium extorquens, with or without further comprising engineered Methylobacterium oryzae, maintained with an indoor ornamental plant, wherein the system exhibits increased VOC removal when compared to a system comprising a plant not cultivated or maintained in the presence of the composition comprising engineered microbes. Said claims encompass within their scope or read on instant claims directed to a composition comprising engineered Pseudomonas putida cells having greater capacity to remove and/or metabolize a VOC and have increased tolerance to VOC when compared to the parental Pseudomonas putida strain PpF1 and further comprising the ornamental indoor plant Epiprenumnum aureum. As in In re Basell Pollolefine Italia S.P.A., 89 USPQ2d 1030, 1036 (Fed. Cir. 2008), the specification of the co-pending ‘959 application at least at sections [416], [547], [552], [554] and [555] as well as at Embodiment 60 specifically identify the PpF1 strain as a Pseudomonas putida strain indicating that the PpF1 strain is intended to fall within the meaning and coverage of the claims. Note that ‘[The specification] may be used to learn the meaning of terms and in interpreting the coverage of a claim’ [Emphasis added]. In re Basell Pollolefine Italia S.P.A., 89 USPQ2d 1030, 1036 (Fed. Cir. 2008). This is a provisional non-statutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claim(s) Objection - Suggestion 14) Claim 50 is objected to for the non-italicized recitation ‘Epipremnum aureum’. To be consistent with the italicized format used in claims 48, 49 and 52-54 and with the practice in the art of botanical nomenclature, it is suggested that Applicants delete the above-identified non-italicized limitation via strikethrough Epipremnum aureum and replace it with the italicized limitation marked by underlining, i.e., Epipremnum aureum’. Conclusion 15) No claims are allowed. Correspondence 16) Any inquiry concerning this communication or earlier communications from the Examiner should be directed to S. Devi, Ph.D., whose telephone number is (571) 272-0854. A message may be left on the Examiner’s voice mail system.
