Office Action

§112
DETAILED CORRESPONDENCE Summary This Office Correspondence is based on the Amendment filed with the Office on 30 January 2026, regarding the Kauffmann, et al. application. Claims 1-5, 7-16 and 21 are currently pending and have been fully considered. 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 5 and 12-13 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. Independent claim 1 has been amended to recite, “… wherein the capillary is manufactured from a plastic material …” However, claim 5, which is drawn dependent from claim 1, recites, “… wherein the capillary is manufactured from a glass material.” Additionally, claim 12, drawn ultimately depended from claim 1, recites, “… wherein the capillary is a quartz theta capillary.” Since claim 1 sets forth that the capillary is manufactured from a plastic material, it is unclear why claims 5 and 12 would have the capillary based on a glass/quartz material instead. Therefore, claims 5 and 12 are rejected as being indefinite for failing to particularly point out and distinctly claim the subject matter. Claim 13 is rejected based on its dependency upon claim 12. Allowable Subject Matter Claims 1-4, 7-11, 14-16 and 21 are allowed. The following is a statement of reasons for the indication of allowable subject matter: The previously cited Yasukawa (Analytical Chemistry, 71(21): p. 4637-4641, Oct 1999) and Yang (Analytical Chemistry, 81(17): p. 7496-7500, Sept 2009) references are considered the closest prior art to the allowable claims. However, neither reference anticipates or renders obvious i) wherein the capillary is manufactured from a plastic material, as required by amended independent claim 1; ii) wherein the plurality of electrodes includes at least one working electrode and at least one quasi-reference/counter electrode, as required by independent claim 21; or iii) further comprising a step of sealing the electrode surface with a liquid sealant after the step of exposing the wire through the electrode surface, as required by independent claim 14. Response to Arguments Applicant’s arguments, filed 30 January 2026, with respect to the prior art rejections to the claims have been fully considered and are persuasive. The prior art rejections have been withdrawn. Applicant’s arguments, filed 30 January 2026, with respect to the drawings have been fully considered and are persuasive. The objection of the drawings has been withdrawn. Interview with the Examiner If at any point during the prosecution it is believe an interview with the Examiner would further the prosecution of an application, please consider this option. The Automated Interview Request form (AIR) is available to request an interview to be scheduled with the Examiner. First, an authorization for internet communications regarding the case should be filed prior or with an AIR online request. The internet communication authorization form (SB/0439), which authorizes or withdraws authorization for internet-based communication (e.g., video conferencing, email, etc.) for the application must be signed by the applicant or the attorney/agent for applicant. The form can be found at: https://www.uspto.gov/sites/default/files/documents/sb0439.pdf The AIR form can be filled out online, and is automatically forwarded to the Examiner, who will call to confirm a requested time and date, or set up a mutually convenient time for the interview. The form can be found at: https://www.uspto.gov/patent/uspto-automated-interview-request-air-form.html The Examiner encourages, but does not require, interviews by the USPTO Microsoft Teams video conferencing. This system allows for file-sharing along audio conferencing. Microsoft Teams can be used as an internet browser add-on in Microsoft IE, Google Chrome, or Mozilla Foxfire, or as a temporary Java-based application on these browsers. Steps for joining an Examiner setup Microsoft Teams can be found at the USPTO website: https://www.uspto.gov/patents/laws/interview-practice#step3 Additionally, a blank email to the Examiner at the time of a telephonic interview can be used for a reply to easily allow for Microsoft Teams communication. Please note, policy guidelines regarding Internet communications are detailed at MPEP §500-502.3, and office policy regarding interviews are detailed at MPEP §713. 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.
