Office Action

§102
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 . Preliminary Remarks The amendment filed on 07/02/2026 has been entered. Claims 2-17 have been amended, no claims have been canceled, and claims 18-19 have bene added. Therefore, claims 1-19 remain pending in the application. Claim Objections Claims 2-17 have been amended to overcome the previously cited claim objection of said claims in the Office Action mailed on 04/02/2026. Claim Rejections - 35 USC § 102 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. 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. Claims 1-8 and 10-17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Gaitas (US 2018/0238498A1; hereinafter “Gaitas”).

Regarding claim 19, Gaitas discloses further comprising a pipette positioning system configured to position an end of the distal section of the pipette at a point relative to the biological sample (pipette 102 is shown in Fig. 1A, having a proximal section and a distal section, which is typical of pipettes; the probe functions as a nanoscale pipette allowing the extraction of biomolecular contents of individual nucleus or other organelles of a cell, para. [0052], lines 9-11). Response to Arguments Applicant's arguments filed 07/02/2026 have been fully considered but they are not persuasive. Page 1 of applicant’s remarks addresses the status of the claims, the interview summary (interview was held on 06/26/26), and objection to claims 2-17, which were cited in the Office Action mailed on 04/02/2026. Applicant’s arguments begin on page 7. Independent claim 1 of the instant application is recited on the top of page 7 of applicant’s remarks. Applicant asserts the following, regarding the primary reference, “Gaitas, does not disclose expressly or inherently, at least the features of claim 1 emphasized above. Gaitas discloses micro-arm or lab-on-a-pipette devices that use suction to collect, aspirate, or manipulate a cell or intracellular biomolecular material. Gaitas also discloses piezoelectric components for movement, positioning, displacement sensing, or force feedback of a probe or apparatus.” Additionally, applicant asserts However, Gaitas has no disclosure, express or inherent, of using a piezo actuator to vibrate a pipette, as claim 1 requires. More particularly, Gaitas does not disclose using a piezo actuator to vibrate a pipette in a way that removes cells surrounding a biological sample. The Office Action appears to conflate controlling the position of a pipette, which is well-known in the art, with vibrating the pipette to remove cells, as recited by claim 1. The distinction between vibrating a pipette and positioning the pipette is made even more clear with reference to claim 2. Claim 2, which depends from claim 1, separately recites a pipette positioning system configured to position an end of the distal section of the pipette. In other words, positioning the pipette at a particular location is distinct from vibrating the pipette to remove cells at that location. Also, applicant asserts: “specifically, the Office Action points to specialized micromanipulators used to move the apparatus of Gaitas ([0075]). However, Gaitas only broadly defines that these micromanipulators can be piezoelectric and that they may be used for general movement of the device. Gaitas does not describe using these micromanipulators-or any other device-to create vibrations that remove surrounding cells from a sample. The Office Action also points to [0052] of Gaitas, but that passage of Gaitas discusses extracting intracellular/nuclear material from a cell so that the cell does not have to be extracted from its environment.” In response, the Office Action mailed on 04/02/2026 was not conflated but merely actual facts and features as disclosed on the Gaitas reference. During the interview on June 26, 2026, the Examiner not only directed the attorney of record to paragraph [0075] of Gaitas, but also, to paragraph [0049] of the same reference. More specifically, paragraph [0075] discloses specialized micromanipulators (manual or motorized or piezoelectric or other or a combination of the aforementioned) are used to move the apparatus. As discussed during the interview, piezo actuators are not novel in the art and the piezo actuator disclosed in Gaitas is capable of performing the same function as that claimed in independent claim 1 of the instant application. Moreover, paragraph [0049] of Gaitas discloses the device includes a sensing and/or actuating element 122, for element 122 is a piezoelectric or piezoresistive element to sense movement or displacement of the device). That is, the actuating element 122, disclosed in Gaits, is a an actuator or actuating element (as disclosed in Gaitas) and thus, causes movement or displacement of the device. Gaitas also discloses these elements are used to move (actuate) the device (para. [0049]). Also, as discussed during the interview on June 26, 2026, the Examiner discussed the device of disclosed in Gaitas is capable of performing the same function as that recited in independent claim 1, in particular, “the piezo actuator mechanically coupled with the pipette and configured to drive piezo vibration of the pipette…”. The Examiner discussed the Gaitas reference disclosure of the piezo element, where Gaitas clearly describes it can be a piezo actuator, that it also, can provide piezo vibration. The attorney of record also, was not able to articulate how the piezo actuator was able to produce or “drive piezo vibration” other than just reiterating the claimed piezo actuator. Also, as stated above in this section, and cited by the applicant, the Gaitas reference discloses specialized micromanipulators (manual or motorized or piezoelectric or other or a combination of the aforementioned) are used to move the apparatus, para. [0075]) and also, para. [0049], discussed above in this section. The latter citations of Gaitas continue to address the claim limitation of “the piezo actuator mechanically coupled with the pipette and configured to drive piezo vibration of the pipette…”. That is, the latter can provide for piezo actuators to cause piezo vibration, also discussed above. Lastly, applicant asserts on the bottom of page 7 and the top of page 8, “Gaitas does not describe using these micromanipulators or any other device to create vibrations that remove surrounding cells from a sample.” In response, the piezo actuator, element 122, and the specialized manipulators of Gaitas are capable of performing the device function as that of the claimed piezo actuator as claimed in independent claim 1 of the instant application. That is, the actuating element of Gaitas is capable of driving piezo vibration as well for the reasons discussed above in this section. Piezo actuators are well known in the art and are therefore known to convert electrical signals into mechanical (or manual) movement displacement into a rapid response; where vibrations are known to be rapid responses as well. Therefore, claims 1-17 and new claims, 18-19, stand rejected. Conclusion THIS ACTION IS MADE FINAL. 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.
