Office Action

§102 §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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Drawings The drawings are objected to because of the following issues: the drawings are of poor quality with blurry lines and unclear shading (particularly with regard to the zipper). The drawings should be reproduced with appropriate clarity. Further, the sole drawing sheet includes only one drawing, but the drawing is labeled both as figure 1 and figure 2, which is improper. It appears that the intent was to label the body of the storage pillowcase as reference numeral 1 and the full-length zipper as reference numeral 2. The figure should then be identified as fig. 1 as there is no fig. 2. Appropriate correction of the relevant portions of the specification is required. The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the releasable fastener being “along the full-length of the side” must be shown or the feature(s) canceled from the claim(s). As depicted in the sole drawing sheet, it appears that the full-length zipper does not extend for the full-length of the side, instead stopping short of both the left and right corners. No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.

If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Objections Claim 1 is objected to because of the following informalities: improper formatting. The a. and b. formatting should be edited to remove the letter list format. Appropriate correction is required. 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 1 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. Claim 1 recites the limitation "the internal storage" in line 1. There is insufficient antecedent basis for this limitation in the claim. The term “soft” in claim 1 is a relative term which renders the claim indefinite. The term “soft” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Claim 1 recites the limitation "the open cavity" in line 5 and again later in the claim. There is insufficient antecedent basis for this limitation in the claim. Note that a cavity has been recited previously as well as an open side, but no open cavity. Claim 1 recites the limitation "the side arranged to prevent the contents of the cavity from leaving the open end." There is insufficient antecedent basis for this limitation in the claim. No such side has been previously recited. Note that various side margins have been recited and that none have been recited as having that particular function previously. Claim 1 recites the limitation "the open end." There is insufficient antecedent basis for this limitation in the claim. Claim 1 recites the limitation "the side slit" in the second to last line of the claim. There is insufficient antecedent basis for this limitation in the claim. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by Russell et al. (US PG Pub No. 20200214477 and hereinafter “Russell”). Re Claim 1 Russell discloses A pillowcase (36) for the internal storage of voluminous soft items (fig. 1, but note that this is merely intended use; It has been held that the recitation with respect to the matter in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus satisfying the claimed structural limitations. Ex part Masham, 2 USPQ2d 1647 (1987).), comprising: two fabric side panels connected along one common side margin and along two common end margins to define a cavity therein (see fig. 1), said two fabric side panels being unconnected at a remaining side margin thereof to define an open side in communication with the cavity (40; see fig 1), the open cavity being configured to accommodate as contents therein the voluminous soft items (see fig. 1; see note above regarding the recitation which first appears in the preamble of the claim); and a releasable fastener (44) along the full-length of the side arranged to prevent the contents of the cavity from leaving the open end with the releasable fastener in a fastened condition and to allow the contents of the cavity to leave the open cavity via the side slit with the releasable fastener in a released condition (fig. 1; see also [0023]). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The art made of record contains various examples, beyond the reference relied upon above, of pillowcases and similar structures which have two fabric panels which are sealed to each other along three sides and have a releasable fastener along a full-length of the remaining fourth side.
