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 . This non-final Office action is in response to Applicant’s patent application number 18/509,279 filed on 11/14/2023. Currently, claims 1-20 are pending and examined. Drawings 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 lifting device must be shown or the feature(s) canceled from the claim(s). 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. Specification Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. The Abstract is objected because too many words in length. 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. 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. Re claim 1, lines 4-5; a citation “at least one lifting device attached an item of furniture; at least one runner attached to the item of furniture” is confusing and indefinite because the claimed preamble in line 1 cites “A system for raising and lowering furniture” thus “for raising and lowering furniture” is functional and not positively combined with “The system”? Clarification is required. For examination purposes, the claims are being treated as a sub-combination of “A system”. Independent claims 9 and 11 having the same issues as mentioned; therefore, claims 9-20 are also rejected. Re claim 1, line 7; a citation “the room” does not have a proper antecedent basis. Correction is required. Claims 2-8 depending upon the rejected claim 1 are also rejected. Re claim 1, line 8; a citation “the furniture” does not have a proper antecedent basis, unless the Applicant meant “the item of furniture” as cited line 5. Correction is required. Re claim 1, line 8; a citation “the connection” does not have a proper antecedent basis. Correction is required. Re claim 1, line 8; a citation “the lifting device” does not have a proper antecedent basis, unless the Applicant meant “the at least one lifting device”. Correction is required. Re claim 9, line 1; a citation “the height” does not have a proper antecedent basis. Correction is required. Claim 10 depending upon the rejected claim 9 is also rejected. Re claim 9, line 2; a citation “the floor line” does not have a proper antecedent basis. Correction is required. Re claim 9, lines 2-3; a citation “the dwelling” does not have a proper antecedent basis, unless the Applicant meant “the dwelling unit”. Correction is required. Re claim 9, line 2; a citation “the floor” does not have a proper antecedent basis. Correction is required. Re claim 9, line 3; a citation “the lifter” does not have a proper antecedent basis, unless the Applicant meant “the at least one lifter”? Correction is required. Re claim 9, line 3; a citation “the fixture” does not have a proper antecedent basis. Correction is required. Re claim 11, line 1; a citation “the furniture” does not have a proper antecedent basis. Correction is required. Claims 12-20 depending upon the rejected claim 11 are also rejected. Re claim 11, line 2; a citation “the floor line” does not have a proper antecedent basis. Correction is required. Re claim 11, line 3; a citation “the floor…the lifter…the fixture” does not have a proper antecedent basis. Correction is required. Re claim 11, line 5; a citation “at least one lifting device” renders the claim indefinite and confusing because it is unclear whether the same as “at least one lifter” cited in line 2? Clarification is required. Re claim 11, line 9; a citation “the furnishing…the connection” does not have a proper antecedent basis. Correction is required. Re claim 11, line 10; a citation “the at least one channel” does not have a proper antecedent basis, unless the Applicant meant “the at least one vertical channel”? Correction is required. Re claim 16, line 2; a phrase “it” renders the claim indefinite and confusing because it is unclear whether “it” referring to which structure? Clarification is required. Re claim 17, line 2; a citation “the storage zone” does not have a proper antecedent basis. Correction is required. Re claim 18, lines 1-2; a citation “wherein at least one lifting device is attached only on one side of the furniture…” is confusing and indefinite because the independent claim 11 cites “A system for rearranging the furniture” thus “for rearranging the furniture” is functional and not positively combined with “The system”? Clarification is required. 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.
