Office Action

§102 §103
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 Objections Claim(s) 1, 9 and 17 are objected to because of the following informalities: Claim(s) 1, 9 and 17 recite a term “hardware components” in the last line. Examiner suggests amending the term to recite “the hardware components” to restore antecedent clarity. Claim(s) 1, 9 and 17 recite a term “metal detecting operations” in the last but one paragraph. Examiner suggests amending the term to recite “the metal detecting operations” to restore antecedent clarity. Appropriate correction is required. 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 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: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.

Regarding claim 18, Nelson discloses in figure(s) 1-6 the computer-based tool of claim 17, wherein customizing the first configuration for the metal detector includes selecting a product profile (windings 32a and 32b are connected together such that they are wound in opposite directions targeting small target detection) that includes the first set of features, wherein the product profile is configured to support the first classification of metal detecting operations of the metal detector, and wherein customizing the second configuration for the metal detector further includes selecting a product profile that includes the second set of features, wherein the product profile is configured to support the second classification of metal detecting operations of the metal detector (windings 32a and 32b are connected together such that they are wound in same directions targeting large target detection).

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 of this title, 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. Claim(s) 6 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Winter in view of Nelson et al. (US 20050253711; hereinafter Nelson2). Regarding claim(s) 6 and 14, Winter teaches in figure(s) 1-16 the method of claim 1 and the system of claim 9, respectively. Winter does not teach explicitly wherein the second configuration includes downgraded versions of one or more features from the first set of features of the first configuration, wherein the downgraded versions provide lower performance levels compared to those in the first configuration. However, Nelson2 teaches in figure(s) 1-16 wherein the second configuration includes downgraded versions (high bandwidth, low sensitivity snr TD mode versus low bandwidth, high sensitivity snr FD mode tradeoff of metal detector in paras. 8-9 tables 1, 2) of one or more features from the first set of features of the first configuration, wherein the downgraded versions provide lower performance (lower bandwidth) levels compared to those in the first configuration. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Winter by having wherein the second configuration includes downgraded versions of one or more features from the first set of features of the first configuration, wherein the downgraded versions provide lower performance levels compared to those in the first configuration as taught by Nelson2 in order to provide use of known technique to improve similar devices (methods, or products) in the same way as evidenced by "variable inductor transmitter and receiver coil realized via switches connecting coils in series or parallel combinations to achieve high and low bandwidth operation" (para. 48). Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See the List of References cited in the US PT0-892.
