Office Action

§101
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 § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1,12 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim does not fall within at least one of the four categories of patent eligible subject matter (process, machine, manufacture or composition of matter) because: Claims 1,12 recite “memory storing program" which covers forms of non-transitory tangible media and software per se in view of the ordinary and customary meaning of computer program distribution media. Claims 2-11 are rejected to as being dependent upon a rejected base claim. Claim Objections Claims 3,5-7 are objected to because of the following informalities: Claim 3 recites “...estimates a compression characteristic...” should be “.... estimates the compression characteristic...”. Claims 5-7 recite “...estimates a compression characteristic that is a characteristic...” should be “...estimates the compression characteristic that is the characteristic...”. Appropriate correction is required. Allowable Subject Matter Claim 13 is allowed. Reclaims 1-11,13 Prior art reference failed to teach or disclose pre-equalized waveform generation device and method comprising: outputting first waveform data for calibration and second waveform data for calibration represented by an expression having a different order of a time variable from an expression representing the first waveform data; acquiring first compression waveform data indicating a waveform modulated using the first waveform data and compressed via a compression transmission path and acquiring second compression waveform data indicating a waveform modulated using the second waveform data and compressed via the compression transmission path; estimating a compression characteristic that is a characteristic of the compression transmission path by using the first compression waveform data and the second compression waveform data; and calculating pre-equalized waveform data by using ideal compression waveform data generated on a basis of a signal waveform and the compression characteristic. Reclaim 12 Prior art reference failed to teach or disclose A waveform compression device including an intensity modulator and a compression transmission path and to compress a waveform modulated by the intensity modulator via the compression transmission path, the waveform compression device comprising: a processor; and a memory storing a program, upon executed by the processor, to perform a process: to output, to the intensity modulator, first waveform data for calibration and second waveform data for calibration represented by an expression having a different order of a time variable from an expression representing the first waveform data; a distributor disposed at a subsequent stage of the compression transmission path; to acquire, via the distributor, first compression waveform data indicating a waveform modulated by the intensity modulator using the first waveform data and compressed via the compression transmission path and to acquire, via the distributor, second compression waveform data indicating a waveform modulated by the intensity modulator using the second waveform data and compressed via the compression transmission path; to estimate a compression characteristic that is a characteristic of the compression transmission path by using the first compression waveform data and the second compression waveform data; and to generate ideal compression waveform data indicating an ideal compression waveform on a basis of a signal waveform and to calculate pre-equalized waveform data by using the compression characteristic and the ideal compression waveform data. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Prior art reference Hester (et al. US 2005/0190100) discloses RF channel calibration for non-linear FM waveforms.
