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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on May 26th, 2026 has been entered. Specification The specification is objected to as failing to provide proper antecedent basis for the claimed subject matter. See 37 CFR 1.75(d)(1) and MPEP § 608.01(o). Correction of the following is required: The specification fails to disclose non-mechanical non-electrical sensors or non-mechanical non-electrical measurement mechanisms. Paragraph 0019 of the specification discloses a list of non-limiting sensor types. However, fails to disclose how any of them are specifically non-mechanical or non-electrical, or both. This is further aggravated by the disclosure, also in paragraph 0019, that the sensors have to be connected to the processor, which necessarily forces at least the measurement mechanism to be electrical in nature, even if a person of skill in the art still considered the sensor itself to be non-electrical in nature. 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. Claims 1-20 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. Claims 1 contains the limitation: “a second non-mechanical non-electrical sensor configured to measure the same antenna alignment parameter of the same antenna using a second type of non- mechanical non-electrical measurement mechanism; and a processor configured to determine the antenna alignment parameter based on the measurements from the first electromechanical sensor and the second non- mechanical non-electrical sensor”. Claim 11 contains the limitation: “measuring, by a second non-mechanical non-electrical sensor of the antenna monitoring device, the same antenna alignment parameter of the same antenna using a second type of non-mechanical non-electrical measurement mechanism; and determining, by a processor of the antenna monitoring device, the antenna alignment parameter based on the measurements from the first electromechanical sensor and second non-mechanical non-electrical sensor”. Claims 2-10 and 12-20 depend on these two claims and refer back these limitations directly. However, the specification fails to disclose non-mechanical non-electrical sensors or non-mechanical non-electrical measurement mechanisms. Paragraph 0019 of the specification discloses a list of non-limiting sensor types. However, fails to disclose how any of them are specifically non-mechanical or non-electrical, or both. This is further aggravated by the disclosure, also in paragraph 0019, that the sensors have to be connected to the processor, which necessarily forces at least the measurement mechanism to be electrical in nature, even if a person of skill in the art still considered the sensor itself to be non-electrical in nature. Claim Rejections - 35 USC § 103 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 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. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 1-5, 10-15, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Au (US 9502764 B2), herein referred to as Au and further in view of Vock et al.

However, Vock discloses the use of a non-mechanical non-electrical sensor (para. 0306, sensor 542 may include a small gyroscope or an electrolytic type tilt device, and as the sensor is non-mechanical and non-electrical, the measurement mechanism is by nature). Therefore, it would have been obvious to one of ordinary skill in the art prior to the effective filing date to combine the teachings of the references and make the device of Au wherein the second sensor and the second measurement mechanism of is of the non-mechanical non-electrical type, as taught by Vock, to provide at least backup measurement without supplied power.

Regarding claim 12, Au and Vock render obvious all limitations of base claim 11. Au also discloses the first electromechanical sensor comprising a micro electromechanical system (MEMS) sensor (electromechanical sensors, col. 5, lines 26-29).
