Office Action

§103 §112
DETAILED ACTION 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 . Election/Restrictions Applicant’s election without traverse of the specie, PNG media_image1.png 192 247 media_image1.png Greyscale , in the reply filed on 2/2/2026 is acknowledged. As the elected specie is found to be free of art, the search to the next specie, PNG media_image2.png 185 330 media_image2.png Greyscale . Claims 1-3, 40, 41, 45, and 51 read on the specie. Claims 4-5, 7, 11-12, 16, 20,23, 28, 32, 35, 38-39 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected specie, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 2/2/2026. 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 38 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 claim recites the expression “The method of claim 1 further defined as” renders the claim indefinite because it is not clear which part of the method is being further defined. 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) 1-3, 40, 41, 45, and 51 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pisutthanan et al., Chiang Mai J Sci, 2005;32(2):!39-148 in view of Ruiz-Manzano et al., Arch Bronconeumol. 2008;44(10):551-66. Pisutthanan et al. teaches an extracts of Chromolaena odorate, that contain compound 3, has anti-mycobacterium tuberculosis activity (see page 145, Table 3; also page 146, col. 1, first paragraph). Pisutthanan et al. does not teach the additional antibiotics in the method of treating mycobacterium infection. Ruiz-Manzano et al. teaches four-drugs combinations ((isoniazid, rifampicin, pyrazinamide, and ethambutol) being administered for 4 months as the first-line treatment for TB (see page 557, col. 1, 4th paragraph). It would have been obvious to one of ordinary skill in the art at the time of filing to employ the additional antibiotic in combination of the herein claimed specie in the method of treating tuberculosis. One of ordinary skill in the art would have been motivated to employ the additional antibiotic in combination of the herein claimed specie in the method of treating tuberculosis. combining two agents which are known to be useful to treat tuberculosis individually into a single composition useful for the very same purpose is prima facie obvious (See In re Kerkhoven 205 USPQ 1069 (CCPA 1980)).
