Office Action

§112 §DP
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 . Election/Restrictions Applicant's election with traverse of Group I in the reply filed on 8/17/2026 is acknowledged. The traversal is on the ground(s) that the special technical feature in common between groups does offer a contribution over the art of Antonio et al. as Antonio does not teach “a measurement zone arranged above a measuring chamber formed between the electrode support and a floor of the base forming a measuring chamber therebetween. This is not found persuasive because Antonio does teach these features. (See Antonio pg. 26 wherein a chamber having measurement electrodes therein is provided and thus a measurement chamber is formed between the electrodes a floor of the base. Also a “measurement zone” may be any point within the device which may be viewed be a user or microscope and thus above a chamber) The requirement is still deemed proper and is therefore made FINAL. 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 43-45,47,50, and 54 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. Claim 43 recites the limitation "the cell culture liquid medium". There is insufficient antecedent basis for this limitation in the claim. Regarding claim 45, the phrase "for instance" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 47 recites the limitation "the impedance of a cell". There is insufficient antecedent basis for this limitation in the claim. Regarding claim 50, the phrase "for instance" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 54 recites the limitation "the gap". There is insufficient antecedent basis for this limitation in the claim. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 40-43,45,48-50, and 52-54 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of U.S. Patent No. 11,912,976 in view of Dickerson et al. (US 2014/0367260 Regarding claims 40-43 claims 1-15 of US 11,912,976 discloses all the features thereof except the imaging system and computing unit being configured to have a variable focus and thus is configured take multiple images in a z direction. Dickerson discloses a DEP cartridge wherein the cartridge is analyzed by utilizing a microscope and CCD camera, i.e. a camera requiring a computing unit, which allows vertical focus adjustment, i.e. images at different z heigh slices, within the cartridge so that an image of a sample in the cartridge may be accurately obtained. (See Dickerson Abstract [0084] and Fig. 11A.) It would have been obvious to one of ordinary skill in the art at the time of filing to provide a microscope capable of taking images at various focal heights, i.e. z direction slices, as described by Dickerson et al. in the device of US 11,912,976 because doing so allows imaging of separated cells within the device as would be desirable in the device of US 11,912,976. Chiou et al. discloses a dep cartridge which includes a microscope and computing unit Regarding claim 45 the limitations thereof correspond with claim 3 of US 11,912,976. Regarding claim 48 the limitations thereof correspond with claim 5 of US 11,912,976. Regarding claim 49 the limitations thereof correspond with claim 6 of US 11,912,976. Regarding claim 50 the limitations thereof correspond with claims 7 and 9 of US 11,912,976. Regarding claim 52 the limitations thereof correspond with claim 10 of US 11,912,976. Regarding claim 53 the limitations thereof correspond with claim 11 of US 11,912,976. Regarding claim 54 the limitations thereof correspond with claim 15 of US 11,912,976. Claims 44, 46, 47, and 51 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-15 of U.S. Patent No. 11,912,976 in view of Dickerson et al. (US 2014/0367260) as applied to claims above and further in view of Sano et al. (US 2012/0085649). Regarding claims 44, 46, 47, and 51 the claims of U.S. Patent No. 11,912,976 disclose all the limitations as set forth above but do not disclose: the signal generator is configured to scan through different electrode signal frequencies, or apply a plurality of discrete different electrode signal frequencies, during a measurement or over a succession of measurements, and the image capture system and computing unit are configured to measure displacements of a cell for different electrode signal frequencies; the electrodes are insulated with respect to an inside of the measuring chamber by an insulator layer, except for a measurement zone and contacts; the cartridge comprises at least two impedance measurement electrodes configured for measuring the impedance (Zi) of a cell; and the electrodes comprise at least two interdigitated electrodes. Sano discloses a DEP cartridge wherein a signal generator scans through different frequencies (See Sano [0036]-[0044] and Figs. 30B-31D); the electrodes are insulated by an insulator layer (See [0010]-[0011], there are two impedance measurement electrodes (See Sano [0076]) and the device electrodes are interdigitated. (See Sano Figs. 6I and 8D). It would have been obvious to one of ordinary skill in the art at the time of invention to provide the elements of Sato in the device of U.S. Patent No. 11,912,976 because such elements are known in the art to allow for the effective arrangement of electrodes and detection of signals so that sample materials may be effectively separated and detected in an accurate manner as would be desirable in the device of U.S. Patent No. 11,912,976.
