Office Action

§103 §112
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 . Response to Amendment The amendments filed on August 18th 2025 have been entered. Claims 1,3-7,9-16 and 19-23 are currently pending. Applicants’ amendments to claims have overcome the objections set forth in the Non-Final Office Action mailed on May 06th 2025. Claim Rejections - 35 USC § 112 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. Claim 23 and 23 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. The claim recites the first and second capacitors comprise a first and second inductance however, the specifications and drawings never teach that the first and second capacitors can have a first and second inductance value. As such these first and second inductance values constitute new matter. 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 3 and 22-23 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 3 recites the limitation "a second antenna collar". There is insufficient antecedent basis for this limitation in the claim. The claim only recites a first collar, not a first antenna collar, and furthermore it is unclear what an antenna collar is as well as the difference between a collar and an antenna collar. For the purposes of examination, the examiner, as best understood, will interpret the claim to mean “ a second collar comprising the second antenna”. Claims 22-23 recite the limitation “the first capacitor has a first inductance” and “the second capacitor has a second inductance” which render the claim indefinite. It is unclear as to how the capacitors can have a first and second inductance since they are capacitors and the specifications/drawings do not teach this concept. For the purposes of examination, the examiner, as best understood, will interpret the limitation to mean the first and second capacitor have a first and second capacitance to bring the claims more in line with what is taught in paragraphs 52-56 of the specifications. Claim 23 recites the limitation “the second signal path comprises … a second parallel inductor-capacitor circuit that is tuned to reject the first frequency” and “the second signal path comprises the first parallel inductor-capacitor circuit allowing the first frequency to pass through the first parallel inductor-capacitor circuit” which renders the claim indefinite. The term “a second parallel inductor capacitor” and “the first parallel inductor capacitor” lack antecedent basis in the claim since a first parallel inductor capacitor is never claimed. Furthermore it is unclear how the parallel inductor capacitor can be configured to reject a first frequency band but then allow the first frequency band later on and how this helps tune the antenna to a second frequency band. For the purposes of examination, the examiner as best understood, will interpret the claim to mean “the second signal path comprises … a first parallel inductor-capacitor circuit that is tuned to reject the first frequency” and “the second signal path comprises the first parallel inductor-capacitor circuit allowing the second frequency to pass through the first parallel inductor-capacitor circuit. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1, 3, 7, 9-13, 16, and 18-22 are rejected under 35 U.S.C. 103 as being unpatentable over Griffing et al. (IDS Reference US 20190049614A1) in view of Taherian et al (US 20120068712 A1). Regarding Claim 1, Griffing et al. discloses an subassembly configured for attachment to a tole for use in a borehole, the subassembly (Downhole tool 219 or tool body 102 serves as a tool for use in a borehole wherein an a downhole receiver 300 may serve as a subassembly attached to the tool; Paragraph 25-60 as well as figure 2-3 and 19 of Griffing et al.) and comprising: a first antenna configured to transmit or receive a signal to or from a second antenna located on the tool and (Downhole receiver 300 may comprise an antenna 302 that can be a transmitter or receiver that is configured to transmit or receive to a second antenna located on the resistivity tool 1905 which can be disposed on the downhole tool 219 or tool body 102; Paragraph 25-60 and 86-89 as well as figure 2-3 and 19 of Griffing et al.) ; a tuning module configured to tune the first antenna to a first frequency or a second frequency, wherein the first frequency corresponds to a first predetermined distance between the first antenna and the second antenna (Downhole receiver 300 includes an antenna assembly 302 with a first antenna 602 which can be connected to a tuning assembly, which can tune the antenna to operate at a first frequency 702 or a second frequency like 704, frequencies f1-f3 in figure 11 also work, wherein the distance between the first antenna 602 and a second antenna on tool 1905 would inherently correspond to the frequency of operation like a first frequency; Paragraph 38 and 47-61 as well as figure 6-7 of Griffing et al.) and ; and Griffing et al. fails to explicitly disclose the second frequency corresponds to a second predetermined distance between the first antenna and the second antenna. However, Taherian et al. does disclose the second frequency corresponds to a second predetermined distance between the first antenna and the second antenna (Receiver module 61 may be attached to the tool used in the borehole wherein module 61 transmits and receives form a transmitter module 55 wherein 61 can operate in lower frequency bands like 1 Khz to higher bands like 2 MHz wherein as distance between module 55 and 61 decreases, a lower band may be used as seen in figures 2 wherein the distance between 61 and 66 is smaller and figure 4 wherein the distance has increased this showing two frequency bands of operation corresponding to distance between antennas; Paragraph 41-56 and figure 2-5 of Taherian et al.). Therefore, it would have been obvious before the effective filling date of the claimed invention to a person having ordinary skill in the art modify the antenna as taught by Griffing et al. to have the second frequency corresponds to a second predetermined distance between the first antenna and the second antenna as taught by Taherian et al. so during operation, signal loss can be compensated for as the tool is used in deeper depths of investigation (Paragraph 45 and 56 of Taherian et al.). Examiner’s note - Regarding the recitation that an element is “configured to” perform a function, it is the position of the office that such limitations are not positive structural limitations, and thus, only require the ability to so perform. In this case the prior art applied herein is construed as at least possessing such ability. When the structure recited in the reference is substantially identical to that of the claims, claimed properties or functions are presumed to be inherent. The Courts have held that it is well settled that where there is a reason to believe that a functional characteristic would be inherent in the prior art, the burden of proof then shifts to the applicant to provide objective evidence to the contrary. See In re Schreiber, 128 F.3d at 1478, 44 USPQ2d at 1478, 44 USPQ2d at 1432 (Fed. Cir. 1997) (see MPEP § 2112.01, I.).

Regarding Claim 4, Griffing et al. further discloses the subassembly of claim 1, wherein the tuning module is configured to passively tune the first antenna to the first frequency and the second frequency via a first signal path and a second signal path, the tuning module including: the first signal path configured to tune the first antenna to the first frequency, the first signal path including a first capacitor; and the second signal path configured to tune the first antenna to a second frequency, the second signal path including a second capacitor (Tuning assembly of first antenna 600/1014 can include multiple switches 1008-1012 and capacitors C1-C3 to form multiple signal paths shown by tuning points 1002-1006 wherein its tunes the antenna to operate in 3 frequencies f1c-f3c via the 3 paths with each path having a capacitor; Paragraph 59-61 as well as figure 10-11 of Griffing et al.). Griffing et al. and Taherian et al. fails to disclose the second signal path including a first inductor-capacitor (LC) resonant circuit. However, Beste et al. does disclose a second signal path including a first inductor-capacitor (LC) resonant circuit (Antenna 10 operates at 2 frequencies due to 2 paths with the second path comprising a LC circuit 16; Paragraph 11 and figure 1 of Beste et al.). Therefore, it would have been obvious before the effective filling date of the claimed invention to a person having ordinary skill in the art modify the antenna as taught by Griffing et al. and Taherian et al. to have a second signal path including a first inductor-capacitor (LC) resonant circuit as taught by Beste et al. to enable dual-band reception or transmission (Paragraph 11 of Beste et al.). Examiner’s note - Regarding the recitation that an element is “configured to” perform a function, it is the position of the office that such limitations are not positive structural limitations, and thus, only require the ability to so perform. In this case the prior art applied herein is construed as at least possessing such ability. When the structure recited in the reference is substantially identical to that of the claims, claimed properties or functions are presumed to be inherent. The Courts have held that it is well settled that where there is a reason to believe that a functional characteristic would be inherent in the prior art, the burden of proof then shifts to the applicant to provide objective evidence to the contrary.

Response to Arguments Applicant’s arguments with respect to claim(s) 1, 12, and 18 have been considered but are moot because the new ground of rejection does not rely on any combination of references 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. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure US 10633967 B2 discloses a subassembly designed to be attached to a tool for a borehole where location of the assembly can be moved down.
