Regarding claim 17, Ibrahim, Liu, Sakoda, Tomizawa, Xiao/Abeta, Chien and Kleider disclose the Bluetooth communication method according to claim 16, wherein the cited prior art fails to further disclose or fairly suggest before the receiving, by a Bluetooth receiving apparatus, a first Bluetooth data frame from a Bluetooth sending apparatus, the Bluetooth communication method further comprises: negotiating, by the Bluetooth receiving apparatus, a second random number with the Bluetooth sending apparatus, wherein the second random number is used for determining a first time interval, and the first time interval is a time interval for updating a synchronization code in a Bluetooth data frame transmitted between the Bluetooth receiving apparatus and the Bluetooth sending apparatus.
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.
