Office Action

§102 §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 . Claim Rejections - 35 USC § 112 Claims 1-20 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. The use of the term "preferably" make the claims unclear. As such, the metes and bounds of the limitations of the claims are unclear. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-3, 6 and 8-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chunglong (CN 108657592) . Regarding claim 1, Chunglong discloses a paper bag capable of holding potting soil or comparable moist bulk materials, formed from a tubular piece (Fig. 1) comprising at least two paper layers (2, 21, 22), the bonds of the bag being formed with biodegradable adhesive (PVA), wherein the innermost paper layer of the tubular piece has on its outer face a water-repellent coating (3), preferably a PE coating, and at least one of the paper layers has at least on its inner face a darkening colouring (black CPP), preferably black colouring. See Fig. 1; and pg. 4, para. 26 – pg. 7, para. 62. Regarding claim 2, the bag has a bottom at one end of the tubular piece, preferably a cross bottom, block bottom or pinch bottom. See Figs. 1-3. Regarding claim 3, an inner lining preferably formed of paper is inserted into the bottom, and the inner lining is provided with a water-repellent coating, preferably a PE coating, on the outer face facing away from the interior of the bag and/or the inner lining has a darkening colouring, preferably black colouring at least on its inner face facing the interior of the bag. See Fig. 1; and pg. 4, para. 26 – pg. 7, para. 62. Regarding claim 6, the bonding regions of the bag material have no coatings reducing the adhesion and/or are bonded with a water-resistant adhesive component. See, pg. 4, para. 26 – pg. 7, para. 62. Regarding claim 8, the water-repellent paper coatings are implemented as free of plastic, biodegradable, compostable and/or recyclable coatings. See, pg. 4, para. 26 – pg. 7, para. 62. Regarding claim 9, all material layers of the bag are composed of paper and/or comparable biodegradable materials. See, pg. 4, para. 26 – pg. 7, para. 62. Regarding claim 10, the bag is fully compostable and/or recyclable. See, pg. 4, para. 26 – pg. 7, para. 62. Regarding claim 11, the bag is formed as a three-layer paper bag, and the outermost material layer is preferably provided on its outer face with a water-repellent, biodegradable, compostable and/or recyclable coating. See, pg. 4, para. 26 – pg. 7, para. 62. Regarding claim 12, the bag is closed at one end of the tubular piece by suture or a bottom is formed at both ends of the tubular piece, preferably a cross bottom, block bottom or pinch bottom, and preferably a valve is inserted in one bottom for filling the bag. See Figs. 1-3. Regarding claim 13, the bag is closed at both ends of the tubular piece by suture and the tubular piece is formed without or with a side fold extending between the ends. 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) 4, 14, 15 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Chunglong as applied above in further view of Hayes (US 2006/0009611). Regarding claims 4, 14 and 15, Chunglong does not disclose the adhesive as claimed. Hayes, which is drawn to a bag, discloses a biodegradable adhesive that contains starch glue, preferably potato starch glue, and/or a moisture-stable bonding additive, preferably dispersion glue, is admixed to the biodegradable adhesive. See, [0103]. Thus, it 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 to use an adhesive as disclosed by Hayes on the bag of Chunglong in order to achieve the desired level of adhesion. Regarding claim 20, the bonding regions of the bag material have no coatings reducing the adhesion and/or are bonded with a water-resistant adhesive component. See, pg. 4, para. 26 – pg. 7, para. 62. Claim(s) 5, 16 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Chunglong as applied above. Regarding claims 5, 16 and 17, Chunglong does not disclose the weight as claimed. It would have been obvious to one having ordinary skill in the art at the time the invention was made to have the moisture-stable bonding additive be admixed to the biodegradable adhesive with a content of not more than 10% by weight, preferably not more than 7% by weight, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. See In re Aller, 105 USPQ 233. Regarding claims 18 and 19, the bonding regions of the bag material have no coatings reducing the adhesion and/or are bonded with a water-resistant adhesive component. See, pg. 4, para. 26 – pg. 7, para. 62. Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Chunglong as applied above in further view of Raymond (US 2,615,614). Regarding claim 7, Chunglong does not disclose the inner lining as claimed. Raymond, which is drawn to a bag, discloses an inner face of an innermost paper layer and/or the inner face of the inner lining in contact with the filling material are treated with a preferably natural fungicide and/or an antimicrobially acting substance and/or provided with an alkaline application. See Fig. 5. Thus, it 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 to use a preferably natural fungicide and/or an antimicrobially acting substance, as disclosed by Raymond, on the bag of Chunglong in order to prevent fungus, etc. from developing within the bag. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See attached Notice of References Cited.
