`A headset has an earcup with front opening adjacent to an
`annular cushion formed with a plurality of openings facing
`the inside of the earcup that acoustically couples the earcup
`volume to the cushion volume. A driver is seated inside the
`earcup with a microphone adjacent to the driver. Active
`noise reducing circuitry intercouples the driver and micro-
`phone. An acoustic load that may comprise a wire mesh
`resistive cover andlor air mass adjacent the microphone is
`constructed and arranged to reduce the effect of resonances
`in the earcup volume.

`
`Claim 1 is rejected under 35 U.S.C. 102(b) as being anticipated by Gorike et al
`
`(hereafter Gorike) (US 4,005,267).
`
`3
`
`Regarding claim 1, Gorike discloses headset comprising, an earcup having a
`
`front opening adapted to be adjacent to the ear of the user (see Fig. 3), a driver inside
`
`said earcup (col. 7, line 1+), a cushion (14) around the periphery of said front opening
`
`formed with an ear opening constructed and arranged to accommodate the ear of a
`
`user and formed with a plurality of openings ("open pores"; col. 7, line 37) around said
`
`opening constructed (although not explicitly shown, the open pores are inherently
`
`located evenly on the cushion; therefore, some of them arenaround the opening; as
`
`shown in Fig. 3, some holes are located facing the passageway between the cushion)
`
`and arranged to acoustically add the volume of said cushion (although not explicitly
`
`A shown, the open pores are in contact with the coupling volume; therefore, the open
`
`pores would inherently add the volume of the cushion to the coupling volume) to the
`
`volume of said earcup and enhance passive attenuation ("a more or less intense
`
`communication between the coupling volume and the outside air"; col. 7, lines 37-39).
`
`In another embodiment, Fig. 11 illustrates a cushion. As" disclosed in col. 9, lines
`28-33, the cushion is made of sound transmitting material, so it would acoustically add
`
`the volume of the cushion to the volume of the earcup and enhance passive
`
`afienuafion.

`
`The following is a quotation of 35 U.S.C. 103(a) which forms the basis for all
`
`obviousness rejections set forth in this Office action:
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described as set
`forth in section 102 of this title, if the differences between the subject matter sought to be patented and
`the prior art are such that the subject matter as a whole would have been obvious at the time the
`invention was made to a person having ordinary skill in the art to which said subject matter pertains.
`Patentability shall not be negatived by the manner in which the invention was made.
`
`6.
`
`Claims 7-11 and 15-17 are rejected under 35 U.S.C. 103(a) as being
`
`unpatentable over Jones (US007103188B1) in view of Olsson (US005913178A).
`
`Regarding claims 7-9, 11 and 15-17, Jones shows a headset comprising, an
`
`earcup having ‘a front opening (see Fig. 2A) adapted to be adjacent to the ear of the
`
`user (See Fig. 1), a driver (22) inside said earcup, a microphone (28) inside said earcup
`
`_ adjacent to said driver (see Fig. 2A), active noise reducing circuitry (abstract)
`
`intercoupling said microphone (28) and said driver (22) constructed and arranged to
`
`provide active noise reduction, a resistive wire cover (26) positioned over the driver (22)
`
`and the microphone (28; col. 8, lines 55-56) coacting with the driver (22) to substantially
`enclose the microphone (28), the resistive cover (26) and the driver (16) defining a
`
`volume with enclosed air and the microphone (18) therebetween, the enclosed air and
`
`the resistive cover forming an acoustic load (although not_exp|icit|y discussed, the
`
`acoustic load is inherently there caused by the grille and the air).
`
`Jones fails to explicitly discuss that the load reduces the effects of resonances in
`
`the earcup. However, Jones clearly teaches that the resistive cover imparts certain
`
`acoustic properties to the sound system to achieve the desired acoustic response.
`
`Jones further teaches that his/her design would greatly improve the stability of the
`
`
`
`Application/Control Number:
`10/754,094
`Art Unit: 2615
`
`Page 5
`
`system.
`
`It was well known to those in the art that the resonance(s) caused instability.
`
`Olsson teaches that a resistive fine-meshed grille of cross—laid thin wires could be used
`
`for reducing resonance (col. 5, lines 20-26). Thus, it would have been obvious to one of
`
`ordinary skill in the art to modify Jones in view of Olsson by selecting the proper grille in
`
`order to reduce the resonance and obtain stability of the system.
`
`Regarding claim 10, although not explicitly shown, the microphone is inherently
`
`positioned between the grille and the speaker by a holder (could be by any means as
`
`long as the microphone is being properly positioned).
`7.‘
`Claims 1 and 2 are rejected under 35 U.S.C. 103(a) as being unpatentable over
`
`Jones in view of Gorike.
`
`Regarding claims 1 and 2, Jones discloses a headset comprising, an earcup
`
`(Fig. 2A) having abfront opening adapted to be adjacent to the ear of the user (Fig. 1),‘ a
`driver (22) inside said earcup, a cushion (3.0) around the periphery of said front opening
`
`formed with an ear opening constructed and arranged to accommodate the ear of a
`user, a microphone (28) inside said earcup adjacent to said driver, and active noise
`
`reducing circuitry (abstract) intercoupling said microphone (28) and said driver (22)
`
`constructed and arranged to provide active noise reduction, whereby said cushion is
`
`further constructed and arranged to furnish additional damping to help smooth the audio
`
`response at the ear of a user and control stability with the headset off the head (col. 5,
`
`lines 10-22).
`
`‘ Jones fails to disclose that the cushion is formed with a plurality of openings
`
`around the opening constructed and arranged to acoustically add the volume of the
`
`
`
`Application/Control Number:

`
`Page 6
`
`cushion to the volume of the earcup and enhance passive attenuation. Gorike teaches
`
`that the cushion material could be selected depending on how much communication’
`
`between the outside air and the coupling volume is preferred (col. 7, lines 33-38). For
`
`example, foam material with open pores would have a plurality of openings around the
`
`opening of the earcup. Depending on the density of the pores, the passive attenuation
`
`could be enhanced. Thus, it would have been obvious to one of ordinary skill in the art
`
`to modify Jones in view of Gorike by selecting cushion material made with open pores in
`
`order to enhance passive attenuation and communication between the outside air and
`
`the coupling volume.
`
`8.
`
`Claims 3-6 are rejected under.35 U.S.C. 103(a) as being unpatentable over
`
`Jones in view of Gorike as applied to claims 1 and 2 above, and further in view of
`
`Olsson.
`
`Regarding ‘claims 3-6, Jones fails to explicitly show that the grille is a wire mesh
`
`resistive cover. However, Jones clearly teaches that the resistive cover imparts certain
`
`acoustic properties to the sound system to achieve the desired acoustic response.
`
`Jones further teaches that his/her design would greatly improve the stability of the
`
`system.
`
`It was well known to those in the art that the resonance(s) caused instability.
`
`Olsson teaches that a resistive fine—meshed grille of 'cross—laid thin wires could be used
`
`for reducing resonance (col. 5, lines 20-26). Thus, it would have been obvious to one of
`
`ordinary skill in the art to further modify Jones and Gorike in view of Olsson by selecting
`
`the proper grille in order to reduce the resonance and obtain stability of the system.

`
`Response to Arguments
`
`9.
`
`Applicant's arguments filed 12/7/07 have been fully considered but they are not
`
`persuasive.
`
`Applicant argued that examiner used the rejected claim as a blueprint to
`
`reconstruct the claimed invention from the prior art. This is not persuasive. Every '
`
`patent examination requires to use applicant's claim(s) as a guide to search for all
`
`relevant prior art. The rejection for claim 1 is 102(b) as the claimed invention is being
`
`anticipated by Gorike. The claimed openings read on the open pores in Gorike, the
`
`claimed “acoustically add the volume of said cushion to the volume of said earcup"
`
`reads on the inherent feature provided the cushion with open pores, the claimed
`
`"enhance passive attenuation” reads on the phrase as disclosed in col. 7, lines 38-39.
`
`App|icant’s case law citations are irrelevant because the rejection is not based on
`
`obviousness, it is based on anticipation.
`
`Applicant further argued that the cushion 14 in Gorike is acoustically isolated
`from the volume of the earcup. This is not convincing. As t36rike clearly indicated that
`
`the cushion is made of open pores, so the cushion is not acoustically isolated from the
`
`earcup. The open pores will provide acoustic connection between the earcup and some
`
`,space inside the cushion. Furthermore, Gorike clearly discloses that depending on the
`
`cushion material, “a more or less intense communication between the coupling volume
`
`and the outside air”.
`
`If the cushion 14 in Gorike is acoustically isolated from the volume
`
`of the earcup as alleged by application, the communication between the coupling
`
`
`
`Application/Control Number:

`
`Page 8
`
`volume and the outside air cannot be modified or adjusted as suggested in Gorike.
`
`Therefore, applicant clearly does not understand Gorike as a whole.
`
`App|icant's.arguments with respect to claims 7 and 11 have beenconsidered but
`
`are moot in view of the new ground(s) of rejection.
