Office Action

§112
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 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 1-10 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 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite in that it fails to point out what is included or excluded by the claim language. The claim reads “obtaining a first arrival amplitude under a time window after a first arrival time”. It is unclear what this means as an amplitude is a numerical value, a time window is a time interval and an arrival time is a time value. Based on the specification the Examiner believes this is intended to mean obtaining a first arrival amplitude, wherein the first arrival amplitude comprises an average amplitude of the borehole seismic wave data within a time window after the first arrival time. It will be read as such for purposes of examination. This claim is an omnibus type claim. Amendment is required. Claims 2-10 depend from claim 1 and are therefore rejected for the reasons provided above. Claim 2 is further rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite in that it fails to point out what is included or excluded by the claim language. The claim reads “statistically calculating the plurality of obtained inverted wave impedance to obtain final inverted wave impedance”. It is unclear what this means as the obtained inverted wave impedances are obtained so it is not clear how one statistically calculated an obtained value. Based on the specification the Examiner believes this is intended to mean statistically calculating the inverted wave impedance based on the plurality of obtained inverted wave impedances. It will be read as such for purposes of examination. This claim is an omnibus type claim. Amendment is required. Conclusion The prior art which is cited but not relied upon is considered pertinent to applicant's disclosure. The references made herein are done so for the convenience of the applicant. They are in no way intended to be limiting. The prior art should be considered in its entirety.
