Office Action

§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 . Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 5-7 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The newly added limitation that the “dye/colorant is selected to produce a single blended color that approximates…” does not have basis in the specification. The original specification discloses that the dye(s) or colorant(s) is/are selected such to mimic the environment, which is not as it is now claimed, since a single blende color would not mimic the environment. 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. Claims 5-7 are 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. In claim 5 the phrase "colorimetric color analysis" renders the claim vague and indefinite, because said analysis, colorimetric analysis, is done on samples in a solution and therefore, it is unclear how this can be done. By the limitation(s) on claim 6, it seems that it should be a "color analysis or spectrograph/spectrometer." In claim 6 the phrase “colorant avoids” before the added limitation makes the claim vague and indefinite, since it is not understood and thus the metes and bounds of patent protection desired cannot be ascertained. Allowable Subject Matter Claims 5-7 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(a) and (b) or 35 U.S.C. 112 (pre-AIA ), 1st and 2nd paragraph, set forth in this Office action. The following is a statement of reasons for the indication of allowable subject matter: the prior art does not teach nor fairly suggest a process of coloring paper by choosing the dye colorant using color analysis of the landscape or environment and blending the dye(s)/colorants such that approximates the predominant color of the landscape or environment. Response to Arguments Applicant’s arguments with respect to claim(s) 5-7 have been considered but are moot in view of the new ground of rejection. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure “Toilet Paper and Disposable Tissues, Dyed with Natural Dyes that Avoid a Visual Impact on the Natural Environment.” Any inquiry concerning this communication or earlier communications from the examiner should be directed to JOSE A FORTUNA whose telephone number is (571)272-1188.
