Office Action

§102 §103 §112
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 office action is in response to the amendment filed 2/23/26. As directed by the amendment, claims 1-9, 11-16, 18-29, 31-36, 38-40, 42-55, 57, and 59 have been amended and no claims have been added nor cancelled. Claims 2-3, 12, 23-26, 29-30, 36, 38, and 51-54 remain withdrawn as being directed towards non-elected subject matter and claims 1, 4-11, 13-22, 27-28, 31-35, 37, 39-50, and 55-59 are examined below. Drawings The drawings are objected to because Figs. 10-12 are objected to as these figures include lead lines but no reference characters. 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 The following claims are objected to because of the following informalities: Regarding claim 1, the language “second end of at least one hollow puncturing member” (line 19-20 is objected to for a formatting/grammatical error; Examiner suggests amending to read –second end of said at least one hollow puncturing member--. Regarding claim 1, the language “and deliver the same” (line 22) is objected to for potentially vague language. While it is clear that the ‘at least one substance’ is what is being delivered, examiner suggests amending to read –and deliver said at least one substance--. Regarding claim 5, the claim is objected as it does not end with a period punctuation mark. MPEP 608.01(m) states that the form of the claims is such that each claim begins with a capital letter and ends with a period. Periods may not be used elsewhere in the claims except for abbreviations. Regarding claim 7, the language “nosepiece said is reversible” (line 2) is objected to for a typographical/grammatical error; Examiner suggests amending to read –nosepiece is reversible--. Regarding claim 8, the language “throughout which” (line 2) is objected to for a grammatical error; Examiner suggests amending to read –through which--. Regarding claim 10, the language “pressured fluid” (line 2) is objected to for a grammatical/typographical error; Examiner suggests amending to read –pressurized fluid--. Regarding claim 15, the language “at least one said at least one” (section d) and e)) is objected to for a grammatical/typographical error; Examiner suggests amending to read –said at least one substance--. Regarding claim 20, the language “said ends” (line 2) is objected to for consistency in claim terminology to match the language in claim 19 line 2; Examiner suggests amending to read –said at least two ends--. Regarding claim 21, the language “said ends” (line 2) is objected to for consistency in claim terminology to match the language in claim 19 line 2; Examiner suggests amending to read –said at least two ends--. Regarding claim 32, the language “and deliver the same” (line 22) is objected to for potentially vague language. While it is clear that the ‘at least one substance’ is what is being delivered, examiner suggests amending to read –and deliver said at least one substance--. Regarding claim 39, the language “throughout which” (line 2) is objected to for a grammatical error; Examiner suggests amending to read –through which--. Regarding claim 41, the language “pressured fluid” (line 2) is objected to for a grammatical/typographical error; Examiner suggests amending to read –pressurized fluid--. Regarding claim 44, the language “at least one said at least one” (section e)) is objected to for a grammatical/typographical error; Examiner suggests amending to read –said at least one substance--. Regarding claim 48, the language “said ends” (line 2) is objected to for consistency in claim terminology to match the language in claim 47 line 2; Examiner suggests amending to read –said at least two ends--. Regarding claim 49, the language “said ends” (line 2) is objected to for consistency in claim terminology to match the language in claim 47 line 2; Examiner suggests amending to read –said at least two ends--. 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. The following claims 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. Regarding claim 1, the language “said one end” (line 16-17) is unclear as it is not known if this is referring to the at least one first end or the second end (lines 12-13).

Examiner suggests amending to read –said at least one nosepiece cover--. Regarding claim 7, the language “nosepiece cover” (line 2) is unclear as claim 5 line 2 sets forth the possibility of plural nosepiece covers with the language “at least one nosepiece cover” and it is therefore unclear if the language in claim 7 is referring back to each of, or a particular one/subset of, the potential nosepiece covers. Examiner suggests amending to read –said at least one nosepiece cover--. Regarding claim 8, the language “said nosepiece cover” (line 1) is unclear as claim 5 line 2 sets forth the possibility of plural nosepiece covers with the language “at least one nosepiece cover” and it is therefore unclear if the language in claim 8 is referring back to each of, or a particular one/subset of, the potential nosepiece covers. Examiner suggests amending to read –said at least one nosepiece cover--. Claim 14 recites the limitations: “said volume rate” in section g), and “said volume rate” in section i). There is insufficient antecedent basis for this limitation in the claim. Claim 15 recites the limitation "said predetermined volume Vsub" in section c), “said predetermined pressure” in section c), and “said at least one orifice” in section c). There is insufficient antecedent basis for this limitation in the claim. Regarding claim 16, the language “said nosepiece cover” (line 1) is unclear as claim 5 line 2 sets forth the possibility of plural nosepiece covers with the language “at least one nosepiece cover” and it is therefore unclear if the language in claim 16 is referring back to each of, or a particular one/subset of, the potential nosepiece covers. Examiner suggests amending to read –said at least one nosepiece cover--. Regarding claim 28, the language “said first end” (line 15) is unclear as it is not known if this is referring to a particular one or each of the potential plural first ends set forth by the language “at least one first end” (line 13); Examiner suggests amending to read –said at least one first end--. Regarding claim 28, the language “said one end” (line 17) is unclear as it is not known if this is referring to the at least one first end or the second end (lines 13-14). It appears Applicant is intending to refer to the at least one first end and examiner suggests amending to read –said at least one first end--. Regarding claim 28, the language “the first end” (line 19) is unclear as it is not known if this is referring to the at least one first end or the second end (lines 13-14). It appears Applicant is intending to refer to the at least one first end and examiner suggests amending to read –the at least one first end--. Claim 35 recites the limitations “said coupling” in line 1 and "nosepiece cover" in line 2. There is insufficient antecedent basis for this limitation in the claim.

Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claim(s) 7, 16, 35, 37 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shahaf in view of Riccio (4,017,007). Regarding claim 7, the Shahaf device is silent as to including a nosepiece cover which is reversible; however, Riccio teaches a similar substance delivery device with a nozzle cover which is reversible (see Riccio Fig. 3-4, cover 39, col. 6 ln. 28-48). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf device to include a reversible cover piece, as taught by Riccio, in order to provide a protective covering to prevent dust/dirt from clogging the nozzle outlet. Regarding claim 16, the Shahaf device is silent as to removal of a nosepiece obtained by the claimed group; however, Riccio teaches such a nozzle cover removed by the claimed action(s) (see Riccio Fig. 3-4, cover 39, col. 6 ln. 28-48). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf device to include a reversible cover piece, as taught by Riccio, in order to provide a protective covering to prevent dust/dirt from clogging the nozzle outlet. Regarding claim 35, the Shahaf use method is silent as to including a nosepiece cover which is reversible; however, Riccio teaches a similar substance delivery device with a nozzle cover which is reversible (see Riccio Fig. 3-4, cover 39, col. 6 ln. 28-48). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf method to include a reversible cover piece, as taught by Riccio, in order to provide a protective covering to prevent dust/dirt from clogging the nozzle outlet. Regarding claim 37, the Shahaf use method is silent as to removal of a nosepiece obtained by the claimed group; however, Riccio teaches such a nozzle cover removed by the claimed action(s) (see Riccio Fig. 3-4, cover 39, col. 6 ln. 28-48). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf method to include a reversible cover piece, as taught by Riccio, in order to provide a protective covering to prevent dust/dirt from clogging the nozzle outlet. Claim(s) 11 and 42 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shahaf in view of Sullivan et al. (2005/0188985). Regarding claim 11, the Shahaf device is silent as to the capsule explicitly being made of at least one material selected from the claimed group; however, Sullivan teaches a similar device/method which includes a capsule made of such a claimed material (see Sullivan para. 0030). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf device’s capsule to be made of a material, such as taught by Sullivan, as this would have been obvious substitution of one known element/material for another and one would expect the modified Shahaf device to perform equally as well. Regarding claim 42, the Shahaf use method is silent as to the capsule explicitly being made of at least one material selected from the claimed group; however, Sullivan teaches a similar device/method which includes a capsule made of such a claimed material (see Sullivan para. 0030). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf method’s capsule to be made of a material, such as taught by Sullivan, as this would have been obvious substitution of one known element/material for another and one would expect the modified Shahaf method to perform equally as well. Claim(s) 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shahaf in view of Weston (6,135,979). Regarding claim 17, the Shahaf device is silent as to including a safety latch shaped to prevent accidental operation; however, Weston teaches a similar substance delivery device including a safety latch as claimed (see Weston Fig. 2a-c, col. 3 ln. 55 through col. 4 ln. 18, safety latch 108). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf device to include a safety latch, as taught by Weston, in order to prevent accidental firing of the device (see Weston col. 3 ln. 55 through col. 4 ln. 18). Claim(s) 20 and 48 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shahaf in view of Bruna et al. (WO 99/46055). Regarding claims 20 and 48, the Shahaf device/method is silent as to the capsule including at least one spherical element positioned at at least one end to prevent leakage therefrom; however, Bruna teaches a similar substance delivery device/method which includes a capsule sealed at an end by at least one spherical element (see Bruna Fig. 1-5, spherical element 16, see also Fig. 6-8). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the Shahaf device/method to include a spherical element to close an end of the capsule, as taught by Bruna, as this would have been obvious substitution of one known element for another (spherical ball for a septum) and one would expect the modified Shahaf device to perform equally as well. Claim(s) 21-22 and 49-50 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shahaf and Bruna as applied to claim 20 above, and further in view of Jensen et al. (EP 2002856). Regarding claims 21 and 49, the modified Shahaf device/method is silent as to the capsule including two spherical elements at each end as claimed; however, Jensen teaches a similar device which includes such a capsule having plural spherical elements (see Jensen Fig. 1-2, spherical elements 111). Thus it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the modified Shahaf device/method’s capsule to include plural spherical elements, as taught by Jensen, in order to provide the ability to have plural types of substances for mixing and delivery at the same time (Jensen abstract). Regarding claims 22 and 50, the modified Shahaf device/method’s two spherical elements are adapted to mix substances therein (see Jensen Fig. 1-2 and abstract). Response to Arguments Applicant’s arguments with respect to the claims have been considered but are moot because the new ground of rejection does not rely on the same reference(s) applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
