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 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 11 and 23 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. A broad range or limitation together with a narrow range or limitation that falls within the broad range or limitation (in the same claim) may be considered indefinite if the resulting claim does not clearly set forth the metes and bounds of the patent protection desired. See MPEP § 2173.05(c). In the present instance, claim 11 recites the broad recitation “at least 90”, and the claim also recites “120, 150, or 180 degrees” which are the narrower statements of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. In the present instance, claim 23 recites the broad recitation “a polyolefin”, and the claim also recites “preferably polyethylene and/or polypropylene” which are the narrower statements of the range/limitation. The claim(s) are considered indefinite because there is a question or doubt as to whether the feature introduced by such narrower language is (a) merely exemplary of the remainder of the claim, and therefore not required, or (b) a required feature of the claims. Allowable Subject Matter Claims 1, 7-10, 12-15, 17-20, 24-27, and 30 are allowed. Claims 11 and 23 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: The prior art of record does not disclose the claimed invention. U.S. Patents 4,462,510 and 4,909,478 are made herein of record but not relied upon for any rejection. U.S. Patents 4,462,510 to Steer et al. and 4,909,478 to Steer both disclose fluid collection bags having an outlet valve wherein the outlet valve comprises a handle that is rotatable from a position closer to a first lateral side edge of the bag to a second position closer to a second lateral edge of the bag. However, neither handle comprises a finger hole. The prior art of record therefore does not disclose nor fairly suggest the claimed invention. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. U.S. Patents 4,462,510 and 4,909,478 disclose fluid collection bags having an outlet valve with a handle.
