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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 12/11/2025 has been entered. Response to Arguments Applicant's amendments and arguments filed 12/11/2025 have been fully considered but they are moot in view of new grounds of rejection. Moreover, claim 1 is 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. Applicant discloses a to “receive a usage pattern based on the pressure data”. Here, the specification does not appear to provide support for a received usage pattern that is based specifically on pressure data. Moreover, there is no specific reference to “pressure data”. While pressure is mentioned there is no definition or scope for “pressure data” within the specification. 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 is 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. Applicant discloses a to “receive a usage pattern based on the pressure data”. Here, the specification does not appear to provide support for a received usage pattern that is based specifically on pressure data. Moreover, there is no specific reference to “pressure data”. While pressure is mentioned there is no definition or scope for “pressure data” within the specification. Regarding applicant amendments, Bas (US 2021/0058169 A1) does not specifically disclose however Yairi (US 2015/0077398 A1) discloses receive a usage pattern based on the pressure data (see “pressure data”, [0020]); Bas does not specifically disclose however Yairi discloses the touch sensor data comprising pressure data applied by a body part of a user (see touch sensor data and pressure data [0035]); It would have been obvious to one of ordinary skill in the art at the time of filing to combine the teachings of Yairi with that of Bas. Doing so would conform to well-known standards in the field of invention. 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) 1-5, 7, 9-19 is rejected under 35 U.S.C. 103 as being unpatentable over Bas et al.

As yet another example, during a set-up of the device or at another time, a notification can be presented for the user to hold a device in a manner”, therefore device interaction), the touch sensor data (”translate touch events” by “touch sensor” [0064]) and the calibration data (see “calibration data”, [0045]); and execute a preventative measure to reduce or eliminate effects of the antenna occlusion (see [0039], “manner that prevents hand occlusion of the antenna”); Bas does not specifically disclose however Yairi discloses the touch sensor data comprising pressure data (see touch sensor data and pressure data [0035]) applied by a body part of a user (see “finger” [0033]); It would have been obvious to one of ordinary skill in the art at the time of filing to combine the teachings of Yairi with that of Bas. Doing so would conform to well-known standards. Regarding claim 2, Bas discloses the device of claim 1, wherein the processing circuitry is configured to receive an indication of an impending hand placement associated with the device interaction (see [0039], “a notification can be presented for the user to hold a device in a manner that prevents hand occlusion of the antenna”). Regarding claim 3, Bas discloses the device of claim 1, wherein the indication of device interaction comprises an indication that the device will be used to make a voice call (see “call” [0051]).

Regarding claim 19, Bas discloses the tangible, non-transitory, computer-readable medium of claim 15, wherein the indication comprises a usage pattern (see calls or messages, [0024]). Claim(s) 6, 8 & 20 are rejected under 35 U.S.C. 103 as being unpatentable over Bas et al. (US 2021/0058169 A1) in view of Yairi in further view of Das et al. (US 2024/0196343 A1). Regarding claim 8, Bas discloses a method of claim 7, Bas does not specifically disclose however Das discloses wherein the one or more actions comprising powering off one or more occluded antennas, reducing power to the one or more occluded antennas, increasing power to one or more non-occluded antennas, or any combination thereof (see [0004], wee power of antenna is reduced based on obstruction of the antenna by human body part); It would have been obvious to one of ordinary skill in the art at the time of filing to combine the teachings of Das with that of Bas. Doing so would improve Specific Absorption Rate (SAR) safety. Regarding claims 6 and 20, Bas discloses the device of claim 1 and tangible, non-transitory, computer-readable medium of claim 15, wherein the preventative measure to reduce or eliminate the effects of the antenna occlusion comprises powering off one or more occluded antennas, reducing power to the one or more occluded antennas, increasing power to one or more non-occluded antennas, or any combination thereof (see [0004], wee power of antenna is reduced based on obstruction of the antenna by human body part). It would have been obvious to one of ordinary skill in the art at the time of filing to combine the teachings of Das with that of Bas. Doing so would improve Specific Absorption Rate (SAR) safety.
