Office Action

§102 §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 . This is in response to the application filed 10/18/2024. Information Disclosure Statement The IDS filed 10/18/2024 has been considered. 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 2 and 10 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. Regarding claim 2, as currently: The wireless device of claim 1, wherein the instructions further cause the wireless device to: determine that a Wi-Fi connection is unavailable; and select the first IMSI in response to determining that the Wi-Fi connection is unavailable. The claim is indefinite because it is not clear how the determining steps takes place or what type of conditions occur. For example, there is no clear timing, nor is it clear how this takes place, and would it actually be reselecting the first IMSI? Additional clarity is needed for this claim to clarify what is accomplished with this claim. Also, if the original number is deleted then how do you recover the number? With the determination of the unavailable connection the limitation creates unclear conditions. Regarding claim 10, as currently: The at least one non-transitory, computer-readable storage medium of claim 9, wherein the instructions further cause the system to: determine that a Wi-Fi connection is unavailable; and select the first IMSI in response to determining that the Wi-Fi connection is unavailable. The claim is indefinite because it is not clear how the determining steps takes place or what type of conditions occur. For example, there is no clear timing, nor is it clear how this takes place, and would it actually be reselecting the first IMSI? Additional clarity is needed for this claim to clarify what is accomplished with this claim. Also, if the original number is deleted then how do you recover the number? With the determination of the unavailable connection the limitation creates unclear conditions. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-20 is/are rejected under 35 U.S.C. 102(a)(1) and/or 102(a)(2) as being anticipated by Bruner et al., US PGPub 2016/0174069 A1. Regarding claim 1, Bruner et al., shows a wireless device comprising: at least one hardware processor; and at least one non-transitory memory storing instructions that, when executed by the at least one hardware processor [0044], cause the wireless device to: select, to fill an empty International Mobile Subscriber Identity (IMSI) value of a bootstrap profile of an Embedded Universal Integrated Circuit Card (eUICC) of the wireless device and using an IMSI provisioning module located on the eUICC (180-188);, a first IMSI from a range of IMSIs stored on the eUICC, the range of IMSIs associated with a mobile network operator; in response to selecting the first IMSI, access a wireless network of the mobile network operator using the first IMSI of the bootstrap profile; in response to accessing the wireless network of the mobile network operator using the first IMSI, receive, over the wireless network, an Embedded Subscriber Identity Module (eSIM) profile comprising a second IMSI associated with the mobile network operator and outside of the range of IMSIs; store, at the eUICC, the eSIM profile; in response to storing the eSIM profile, access the wireless network using the second IMSI of the eSIM profile; and delete the first IMSI of the bootstrap profile (136; Fig. 3; [0032]) from the bootstrap profile (Fig. 1, 3, 6, and 7; [0020], [0024]-[0026] and [0034]-[0040]).
