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 .
Claims 1-20 are pending in this office action.
Allowable Subject Matter
Claims 5-8, 13-16, 19 and 20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Response to Arguments
Applicant’s arguments with respect to the amendment filed 05/19/2026 have been considered but are moot in view of new grounds of rejection.
Claim Rejections - 35 USC § 102
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)(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.
Claims 1-4, 9-12, 17 and 18 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Guthrie et al (US 2020/0119462 A1).
Regarding claim 1, Guthrie teaches a wireless device comprising:
a transmitter; and
logic at least one of coupled to or integrated within the transmitter, the logic to:
generate, based on a portion of a packet to be transmitted during a round-trip timing estimation of an enclosure having a receiver, a frequency domain artifact (Guthrie: Figs. 49-50; [0340]-[0343], [0348]-[0349] generate a cryptographically random variation/artifact in a packet transmitted during RTT estimation); and
cause a frequency of samples of bit patterns of the portion of the packet to be modified based on the artifact before the transmitter transmits the packet to the receiver (Guthrie: Figs. 49-50; [0340]-[0343], [0348]-[0349] generate a cryptographically random variation/artifact in a packet transmitted during RTT estimation; [0381]-[0382] cryptographically random length tones/frequency domain).
Regarding claim 9, Guthrie teaches a method comprising:
generating, by logic of a transmitter and based on a portion of a packet to be transmitted during a round-trip timing estimation of an enclosure having a receiver, a frequency domain artifact (Guthrie: Figs. 49-50; [0340]-[0343], [0348]-[0349] generate a cryptographically random variation/artifact in a packet transmitted during RTT estimation); and
causing a frequency of samples of bit patterns of the portion of the packet to be
modified based on the artifact before the transmitter transmits the packet to the receiver (Guthrie: Figs. 49-50; [0340]-[0343], [0348]-[0349] generate a cryptographically random variation/artifact in a packet transmitted during RTT estimation; [0381]-[0382] cryptographically random length tones/frequency domain).
Regarding claim 17, Guthrie teaches a system comprising: an antenna; a transmission device that is to transmit a packet; a receiving device to receive the pattern; and logic at least one of coupled to or integrated with the transmission device, the logic to:
generate, based on a portion of a packet to be transmitted during a round-trip timing estimation of an enclosure having a receiver, a frequency domain artifact (Guthrie: Figs. 49-50; [0340]-[0343], [0348]-[0349] generate a cryptographically random variation/artifact in a packet transmitted during RTT estimation); and
cause a frequency of samples of bit patterns of the portion of the packet to be
modified based on the artifact before the transmitter transmits the packet to the receiver (Guthrie: Figs. 49-50; [0340]-[0343], [0348]-[0349] generate a cryptographically random variation/artifact in a packet transmitted during RTT estimation; [0381]-[0382] cryptographically random length tones/frequency domain).
Regarding claims 2, 10 and 18, Guthrie teaches wherein to generate the frequency domain artifact, the logic is to: identify one or more bit patterns within the portion of the packet; and modify one or more bit waveforms of the one or more identified bit patterns (Guthrie [0322], [0403]).
Regarding claims 4 and 12, Guthrie teaches wherein to modify the one or more bit waveforms, the logic is to: modify a portion of the one or more bit waveforms in a time domain associated with the portion of the packet (Guthrie: Figs. 57-59; [0381]-[0382] cryptographically random length tones).
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.
Claims 3 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Guthrie et al (US 2020/0119462 A1) in view of Yu (US 2004/0028227 A1).
Regarding claims 3 and 11, Guthrie does not explicitly disclose but Yu teaches wherein to identify the one or more bit patterns, the logic is further to: randomly perform a Boolean operation on the one or more bit patterns to change a value of a portion of a bit waveform of the one or more bit patterns (Yu: [0037], [0063], [0065]-[0066] XOR/Boolean operation).
It would have been obvious to a person having an ordinary skill in the art before the effective filling date of the claimed invention to modify the system of Guthrie wherein to identify the one or more bit patterns, the logic is further to: randomly perform a Boolean operation on the one or more bit patterns to change a value of a portion of a bit waveform of the one or more bit patterns as disclosed by Yu to provide a system for partial encryption of streamed-formatted media (Yu: Abstract).
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.
