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 .
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked.
As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph:
(A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function;
(B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and
(C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function.
Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function.
Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function.
Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
The examiner notes that narrowing expressions of corresponding structure or implementations could not be clearly identified for cases of “means for” as recited in claim 18, and are therefore read according to ordinary language.
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 7-20 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.
Where applicant acts as his or her own lexicographer to specifically define a term of a claim contrary to its ordinary meaning, the written description must clearly redefine the claim term and set forth the uncommon definition so as to put one reasonably skilled in the art on notice that the applicant intended to so redefine that claim term. Process Control Corp. v. HydReclaim Corp., 190 F.3d 1350, 1357, 52 USPQ2d 1029, 1033 (Fed. Cir. 1999).
The term “drive bit” in claims 7-8, 16, and 18 is used by the claim to mean “bit,” a binary digit. While no accepted meaning for the term “drive bit” could be found within typical academic references (encyclopedias, dictionaries, etc), multiple online references, such as bit#2 For Robertson head screw. Flexpipe Inc. 2026, use “drive bit” to refer to “a replaceable part of a compound tool that actually performs the function (such as drilling or boring) for which the whole tool is designed” a bit as defined by Merriam-Webster, 2026. Therefore, the term is indefinite because the specification does not clearly redefine the term.
Claims 9-17 and 19-20 are rejected as they are dependent upon a rejected claim.
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:

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 4-7 are rejected under 35 U.S.C. 103 as being unpatentable over Vasishtha in view of DuBose, US-PG-PUB No. 2009/0287947.
Regarding claim 4, Vasishtha discloses, as explained above, the apparatus of claim 1, but fails to explicitly disclose wherein a power supply comprises a first switch and a second switch for toggling between a low power mode and a high power mode.
DuBose teaches a circuit for low idle power in Bluetooth devices (analogous to the headset of Vasishtha), wherein a power supply comprises (Shown in Fig. 3, primary circuit (210) is part of power supply (200).....¶[0017], lines 1-3) a first switch and a second switch (Shown in Fig. 3, switches S1 and S2 are part of primary circuit (210).....¶[0036], lines 4-5) for toggling between a low power mode (S1 may be designated to put the system in a low power mode.....¶[0036], lines 12-15) and a high power mode (S2 may be used by the power control unit to return the system to active (high power) mode.....¶[0036], lines 18-20).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Vasishtha by DuBose to provide the benefit of where operational power may be saved by physically disengaging circuits of a device (DuBose, ¶[0005], lines 9-11). This would make obvious the feature wherein the power supply comprises a first switch and a second switch for toggling between a low power mode and a high power mode.
Regarding claim 5, the combination of Vasishtha and DuBose, as explained above, teach the apparatus of claim 4.
DuBose additionally teaches a power control module (Shown in Fig. 3, Power Control Unit (232).....¶[0036], lines 1-2) coupled to the power supply (The power control unit is operationally coupled to a power supply, as it controls the power supply state.....¶[0036], lines 1-2, 12-15), the power control module configured to activate the first switch and the second switch (The power control unit controls first and second switches S1 and S2.....¶[0036], lines 1-5).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have further modified the combination of Vasishtha and DuBose by DuBose to provide the benefit of where operational power may be saved by physically disengaging circuits of a device (DuBose, ¶[0005], lines 9-11). This would make obvious the feature of a power control module coupled to the power supply, the power control module configured to activate the first switch and the second switch.
Regarding claim 6, the combination of Vasishtha and DuBose, as explained above, teach the apparatus of claim 5.
Vasishtha additionally teaches wherein the audio peripheral determines the reconfiguration timeline (The assertion and de-assertion time intervals that comprise and determine the reconfiguration timeline are based upon 625 microsecond timeslots, intervals determined by the Bluetooth specification.....¶[0039], lines 5-7, ¶[0018], lines 1-3) from a digital audio (Vasishtha refers to the data received by the apparatus as Bluetooth data packets (¶0016], lines 13-16). Additionally, the apparatus may be embodied in wireless headphones (¶[0016], lines 6-9). Based on the circumstantial evidence of the prior art, the nature of the received data packets is clearly guided towards audio data packets when the apparatus is embodied in wireless headphones) configuration (Assertion and de-assertion time intervals are based upon 625 microsecond timeslots, intervals determined by the Bluetooth specification.....¶[0039], lines 5-7, ¶[0018], lines 1-3).
Regarding claim 7, the combination of Vasishtha and DuBose, as explained above, teach the apparatus of claim 6.
Vasishtha additionally teaches wherein the audio peripheral is further configured to determine an assertion time interval (Shown in Fig. 3, an interval (134) is determined to be long enough for the system to wake and prepare after an assertion to an active state at time (132), thus interval (134) is an assertion time interval.....¶[0043], lines 2-6) prior to the start one drive bit of a plurality of drive bits (While in the active state, the method allows a wireless device to receive Bluetooth data packets from a second device, data packets inherently containing a plurality of bits, such pluralities inherently containing one bit (e.g. a first bit of a first packet).....¶[0014], lines 3-7) based on the reconfiguration timeline (Reconfiguration to an asserted state at time (132) is based upon a sleep/wake cycle (reconfiguration timeline), shown in Fig. 3 and explained in ¶[0042], lines 1-3 and ¶[0043], lines 2-4);
determining a de-assertion time interval (Shown in Fig. 3, an interval of time (122) between when the last data is processed at time (120) and when the method de-asserts to a sleep state at time (124).....¶[0042], lines 4-8), subsequent to the end of the one drive bit of the plurality of drive bits (The interval is used for post-processing activity, thus subsequent to the bit-processing activity denoted at point (104), including the processing of the one (first) bit of the first packet.....¶[0042], lines 5-8, ¶[0040], lines 3-4) based on the reconfiguration timeline (Reconfiguration to a de-asserted state at time (124) is based upon an sleep/wake cycle (reconfiguration timeline), shown in Fig. 3 and explained in ¶[0042], lines 1-3 and ¶[0043], lines 2-4).
Claims 14-16 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Vasishtha in view of BLUETOOTH CORE SPECIFICATION Version 5.3 [online]. Bluetooth SIG Proprietary, 2021 (hereinafter Bluetooth).
Regarding claim 14, Vasishtha discloses the method of claim 13, as explained above, Vasishtha fails to explicitly disclose wherein the digital audio configuration defines a transmission data frame, instead broadly disclosing Bluetooth data packets.
Bluetooth teaches wherein a Bluetooth data connection may utilize the L2CAP layer to provide a data configuration which defines the size of transmission data frames (Pg. 212, section 3.1.1, ¶[1], lines 1-3, ¶[2], lines 1-2).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Vasishtha by Bluetooth to provide the benefit of a digital audio configuration compatible with Bluetooth LE (Low Energy), providing further power efficiency of the device (Bluetooth, 3.1.2, last line). Such modification would make obvious the feature wherein the digital audio configuration defines a transmission data frame.
Regarding claim 15, the combination of Vasishtha and Bluetooth, as explained above, teach the method of claim 14.
Vasishtha additionally teaches wherein the digital audio configuration defines a bit slot sequence (The audio data contains pluralities of bits which are inherently received and processed in a sequence, with packets received in 625 microsecond slots.....¶[0018], lines 1-4), with a relative timeline of a plurality of active loads and a plurality of passive loads (Shown in Fig. 3, activity is aligned to the slots at points (104) and (106), while the device is in the active state, and the device is in a passive state (with passive loads) when in a sleep state.....¶[0040], lines 1-3).
Regarding claim 16, the combination of Vasishtha and Bluetooth, as explained above, teach the method of claim 15.
Vasishtha additionally teaches wherein the reconfiguration timeline includes a plurality of drive bits from the bit slot sequence (Shown in Fig. 3, (showing the timeline which defines how the method reconfigures itself between sleep and active modes), is wireless communication activity marker (104), wherein the apparatus performs wireless and processing activity, including the processing of wireless data (including a plurality of bits) in accordance with the slot sequence of the top row of the figure.....¶[0040], lines 1-3, ¶[0016], lines 13-15).
Regarding claim 20, Vasishtha, as explained above, discloses the apparatus of claim 19.
Vasishtha additionally discloses means for receiving the digital audio configuration (A wireless communication circuit and processor for processing received data.....¶[0067], lines 1-8).
Vasishtha fails to disclose fails to explicitly disclose wherein the digital audio configuration defines a transmission data frame, instead broadly disclosing Bluetooth data packets.
Bluetooth teaches wherein a Bluetooth data connection may utilize the L2CAP layer to provide a data configuration which defines the size of transmission data frames (Pg. 212, section 3.1.1, ¶[1], lines 1-3, ¶[2], lines 1-2).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Vasishtha by Bluetooth to provide the benefit of a digital audio configuration compatible with Bluetooth LE (Low Energy), providing further power efficiency of the device (Bluetooth, 3.1.2, last line). Such modification would make obvious the feature wherein the digital audio configuration defines a transmission data frame.
Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Vasishtha in view of Bluetooth in further view of Trajmar et al (hereinafter Trajmar), US Patent No. 8,098,737 with further evidence provided by DDR SDRAM [online]. Wikipedia.org, 2023 (hereinafter DDR SDRAM).
Regarding claim 17, the combination of Vasishtha and Bluetooth, as explained above, teach the method of claim 16, but fail to teach wherein the bit slot sequence operates in a double data rate (DDR) mode where bit slot boundaries occur on both rising edge and falling edge of a transport clock.
Trajmar teaches an audio data transport method utilizing DDR (double data rate) SD Random Access Memory, thus enabling the bit slot sequence (data being processed for transport, analogous to the data being processed of Vasishtha) to operate in a double data rate mode, where bit slot boundaries occur on both rising edge and falling edge of a transport clock (DDR interfaces inherently transfer (transport) data (defining the bit slot boundaries) on rising and falling edges of the transfer clock signal, evidenced in “DDR SDRAM”, ¶2, lines 4-7).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the combination of Vasishtha and Bluetooth by Trajmar to provide the benefit of nearly double the data bandwidth (“DDR SDRAM”, ¶2, lines 7-9). Such modification would make obvious the feature wherein the bit slot sequence operates in a double data rate (DDR) mode where bit slot boundaries occur on both rising edge and falling edge of a transport clock.
