Office Action

§112
DETAILED ACTION In the response to this office action, the examiner respectfully requests that support be shown for language added to any original claims on amendment and any new claims. That is, indicate support for newly added claim language by specifically pointing to page(s) and line numbers in the specification and/or drawing figure(s). This will assist the examiner in prosecuting this application. 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 Objections Claims 3 and 6 are objected to because of the following informalities: Claim 3 states “each of the sets of speakers is arranged in front of the listening zone” which would be better as “each of the plurality of speakers is arranged in front of the listening zone” since no sets of speakers was previously mentioned. Claim 6 states “at a boundary of a space, including the plurality of sets of speakers yet not including the listening zone, the boundary of the space being located toward the listening zone” which would be better as “at a boundary of a space, including the plurality of speakers yet not including the listening zone, the boundary of the space being located toward the listening zone” since no sets of speakers was previously mentioned. Appropriate correction is required. 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. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: a first sound field control part in claim 1. a second sound field control part in claim 1. a transfer characteristic setting part in claim 4. a masker generating part in claim 5. 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. 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. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: 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 of carrying out his invention. Claim 1-6 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. Regarding Wands factors: (A) The breadth of the claims: The claims are fairly broad describing minimal hardware including speakers, filters and “mixers” (disclosed as adders in the written description), then describing a desired sound field including a target sound and masking sound.; (B) The nature of the invention: The invention is to providing sound to a listener while masking the sound to other areas and people in the surrounding area.; (C) The state of the prior art and (D) The level of one of ordinary skill: The use of masking sounds to cover up sounds is well known, as is the ability to selectively deliver sound to various areas, normally along angles from speaker arrays. However leakage still exists and creating distinct boundaries for audio of any geometry is not widely known.; (E) The level of predictability in the art: Creating a masking sound that effectively masks a given sound is known in the art and predictably successful. Creating directive speaker lobes and nulls along angles from a speaker array is very predictable. Creating sound fields with any chosen geometry is not a predictable endeavor and requires much guidance from designers for success.: (F) The amount of direction provided by the inventor: Applicant has provided sketches of desired audio zones and boundaries, however no direction on how to calculate the filters required to make the geometries show in the figures or described by the claims. Applicant only refers to prior art “to control the sound field so that the listening target sound, which is the sound that a user is listening to, is audible only to the user, there is known a technology of local sound reproduction that minimizes magnitude of the listening target sound propagating outside a first zone (see applicant’s paragraph [0003]). No prior art is provided that has a sound field with a distinct boundary, planar or otherwise, that creates sound only outside a listener’s area.; (G) The existence of working examples and (H) The quantity of experimentation needed to make or use the invention based on the content of the disclosure: No working examples are provided by the applicant. Designing and creating the filters required to create the geometry of the claims would take a great amount of experimentation and success levels may vary greatly. Each area of implementation (room A versus room B for example) would have its own obstacles and the filters would need to be customized. A great amount of trial and error would have to take place to create even a moderately working design. Therefore, one of ordinary skill in the art could not make and use the invention without undue experimentation. 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. Claim 1-6 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. Claim 1 states “as closely as possible” in “a sound pressure gradient of the masker approach zero as closely as possible” which is unclear. It is unclear how close to zero this is, and by who’s standards this being compared to. Given some arrangements it may not be possible to get very close to zero, however getting “as close as possible” may still be met. The scope is not well defined. Claims 2, 3, and 6 are rejected in an analogous manner for using “as closely as possible” language. Claims 3-5 are rejected as inheriting the problems as above.
