Office Action

§102 §112
Detailed Action begins on Page 3 Table of Contents Notice of Pre-AIA or AIA Status 3 Drawings 3 Claim Objections 4 Claim Rejections - 35 USC § 112(a) 6 Claims 13 and 15 6 Claim Rejections - 35 USC § 112(b) 8 Claim 8 8 Claim Rejections - 35 USC § 102 9 Claims 1-9, 14, and 16-18 9 Claims 1, 7, and 10 12 Claims 1, 7, 8 and 11-12 14 Citation of Relevant Art 15 Conclusion 17 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 . 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, in claim 12 the limitation “wherein said first display wheel set and said second display wheel set are coaxial rollers, and are at least partially overlapping in said display area” must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Additionally, claim 13 recites the limitation “wherein the display wheel set of said display wheel sets which has the lowest number of positions has a viewing window adjacent to each of its indicators and through which the other of said display wheel sets is visible” and this claim depends from claim 12. No drawings are provided showing the claimed partial overlap with coaxial rollers and further do not include a viewing window when the display wheels sets are coaxial rollers. The drawings are objected to under 37 CFR 1.83(a) because they fail to show “More particularly, the first display wheel set 10 and the second display wheel set 20 are coaxial rollers, and are at least partially overlapping in the display area 30.” as described in paragraph [0029] of the specification. Any structural detail that is essential for a proper understanding of the disclosed invention should be shown in the drawing. MPEP § 608.02(d). The structural detail of the first and second display wheel sets being coaxial and partially overlapping is shown for when the display wheel sets are discs [fig. 10] but not when they are coaxial rollers. Paragraph [0029] does not point to a particular figure showing the “partially overlapping” feature for the coaxial rollers, and figure 6 and 15 showing the display wheel sets as coaxial rollers do show this feature. Either there is another meaning being given to “partially overlapping in the display area” than a person of ordinary skill in the art would interpret it, or this feature is not included in the drawings. 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. Claim Objections Claims 6-7 and 9-11 are objected to because of minor informalities. Claim 6 recites “according to claims 2” and the plural “claims” should instead recite the singular “claim” when referring to the display mechanism according to claim 2. Claims 6 recites “and in that said coupling elements comprise” and the use “in that” as a transitional phrase should be replaced or removed because as currently written it is unclear if it is requiring a further narrowing of a previously recited limitation or an elaboration of what the previous limitation requires, or if it is meant to be a transition phrase along the lines “and additionally” or “and wherein”. The grammar of “in that” is confusing as currently written and requires fixing. Claim 7 recites “n that said second display wheel set comprises” and “in that said display area is arranged” and the use “in that” as a transitional phrase should be replaced or removed because as currently written it is unclear if it is requiring a further narrowing of a previously recited limitation or an elaboration of what the previous limitation requires, or if it is meant to be a transition phrase along the lines “and additionally” or “and wherein”. The grammar of “in that” is confusing as currently written and requires fixing. Claim 9 recites “and in that that the display wheel set of said display wheel sets which has the smallest number of positions has a viewing window” and the use “in that” as a transitional phrase should be replaced or removed because as currently written it is unclear if it is requiring a further narrowing of a previously recited limitation or an elaboration of what the previous limitation requires, or if it is meant to be a transition phrase along the lines “and additionally” or “and wherein”. The grammar of “in that” is confusing as currently written and requires fixing. Claim 10 recites “and in that that the display wheel set of said display wheel sets which has the smallest number of positions has a viewing window” and the use “in that” as a transitional phrase should be replaced or removed because as currently written it is unclear if it is requiring a further narrowing of a previously recited limitation or an elaboration of what the previous limitation requires, or if it is meant to be a transition phrase along the lines “and additionally” or “and wherein”. The grammar of “in that” is confusing as currently written and requires fixing. Claim 11 recites “and in that said first indicators and said second indicators are always spaced apart” and the use “in that” as a transitional phrase should be replaced or removed because as currently written it is unclear if it is requiring a further narrowing of a previously recited limitation or an elaboration of what the previous limitation requires, or if it is meant to be a transition phrase along the lines “and additionally” or “and wherein”. The grammar of “in that” is confusing as currently written and requires fixing. Appropriate correction is required. Claim Rejections - 35 USC § 112(a) 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 13 and 15 Claims 13 and 15 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. Regarding Claim 13, it recites the limitation “wherein the display wheel set of said display wheel sets which has the lowest number of positions has a viewing window adjacent to each of its indicators and through which the other of said display wheel sets is visible” and this claim depends from claim 12 which recites the limitation “wherein said first display wheel set and said second display wheel set are coaxial rollers”. While paragraph [0030] of the specification recites “More particularly, the rolling display wheel set of the rolling display wheel sets 10, 20 that has the smallest number of positions has a viewing window 18, 28, adjacent to each of its indicators 11, 21, and through which the other of the display wheel sets 20, 10 is visible, for the combined and aligned display of a first indicator 11 and a second indicator 21 in the display area 30” there is not any details into how this viewing window is accomplished for coaxial rollers. The drawings do not show this claimed feature and a person having ordinary skill in the art would not find the addition of the viewing window a simple or well understood feature for display wheel sets that are coaxial rollers and without additional details on how this is accomplished there is insufficient written description support to show that the inventor had possession of the claimed invention. Regarding Claim 15, it recites the limitation “wherein said first display wheel set is a units display wheel set with 5 positions and rotational sections corresponding to the digits from 0 to 9” and it is not described in sufficient detail in the specification or shown in the drawings how a unit display wheel with digits from 0 to 9 is accomplished by a display wheel set with 5 positions and rotational sections. Details into how the “rotational sections” part of the limitation would increase the number of digits to the ten required for 0 to 9 when there only 5 positions are not recited. Without any written description for this feature, the specification does not appear to provide support for more than five digits when there are five positions claimed. Claim Rejections - 35 USC § 112(b) 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 8 Claim 8 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. Regarding Claim 8, it recites the limitation “wherein said first display wheel set and/or said second display wheel set comprises a plurality of said first indicators, respectively second indicators, which are identical to each other” and the part of this limitation reciting “respectively second indicators” is not clear in what it requires of the claim, if anything at all, based on the current grammar and punctuation. If the claim is intended to have the first display wheel set comprise the plurality of first indicators and/or the second display wheel set comprise the second indicators it should be rewritten to more clearly claim because currently “respectively second indicators” does require anything due to not making grammatical sense. 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.
