Office Action

§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 Applicants’ amendments filed 02/17/2026 with respect to claims 1 and 11 have been considered and they are addressed in this Office Action. The symbol of “MCH” is spelled out in claims 1 and 11. The rejection of dependent claims 5 and 15 under 35 U.S.C. 112(b) as being indefinite is withdrawn. Claims 4 and 14 are canceled. Claims 1 – 3, 5 – 13, and 15 – 20 are pending. 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. Claims 1 and 11 are rejected under 35 U.S.C. 112(a) as failing to comply with the written description requirement. According to Applicants’ specification, Figure 10 illustrates a process in which a 3GPP signal and an ATSC 3.0 signal are alternately transmitted within a time-division period when an MSP is set as the time-division period. Figure 12 illustrates a process in which a 3GPP signal and an ATSC 3.0 signal are alternately transmitted within a time-division period when a multiple of an MSP is set as the time-division period. Claims 1 and 11 recite the claimed features of “wherein the period information is set such that the period aligns with a Multicast Channel (MCH) scheduling period (MSP) to create a blank interval for transmitting the signal of the non- 3GPP broadcasting technology” which were 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 at the time the application was filed, had possession of the claimed invention. Allowable Subject Matter Applicants’ amendments to claims 1 and 11 have been considered. Choi does not disclose the claimed features of “wherein the communication signal is based on the 3GPP standard and the signal of other physical layer is based on a non-3GPP broadcasting technology, and wherein the period information is set such that the period aligns with a Multicast Channel (MCH) scheduling period (MSP) to create a blank interval for transmitting the signal of the non- 3GPP broadcasting technology” as recited in claims 1 and 11 when considering each claim individually as a whole. Conclusion THIS ACTION IS MADE FINAL. 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.
