Office Action

§101 §112
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 . DETAILED ACTION Priority 1. Receipt is acknowledged of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement 2. The information disclosure statement (IDS) submitted on 06/22/2026 has been considered by Examiner and made of record in the application file. Claim Rejections - 35 USC § 112 3. 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. 4. Claims 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 pre-AIA the applicant regards as the invention. Claim 1 recites the limitation "the clusters" in line 5; the term “clusters" is not previously presented in the claim. There is insufficient antecedent basis for these limitation in the claim. Claims 2-6 depend on claim 1. Therefore, the rejection of claims 2-6 are rejected the same reason as the rejection of claim 1 set forth above. Claim Rejections - 35 USC § 101 5. 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 1-6 rejected under 35 U.S.C. 101 as not falling within one of the four statutory categories of invention. Supreme Court precedent1 and recent Federal Circuit decisions2 indicate that a statutory “process” under 35 U.S.C. 101 must (1) be tied to another statutory category (such as a particular apparatus), or (2) transform underlying subject matter (such as an article or material) to a different state or thing. While the instant claim recites a series of steps or acts to be performed, the claim neither transforms underlying subject matter nor positively ties to another statutory category that accomplishes the claimed method steps, and therefore does not qualify as a statutory process. For example: The claim 1 language only describes “a geometry-based stochastic channel modeling method oriented to a wireless communication in an underground mine”, is of sufficient breadth that it would be reasonably interpreted as a series of steps completely performed mentally, verbally or without a machine. The Applicant has provided no explicit and deliberate definitions of "generating", “introducing” or "calculating" to limit the steps to the electronic form of the “geometry-based stochastic channel modeling question" and the claim language itself is sufficiently broad to read on a geometry-based stochastic channel modeling question about §101, mentally stepping through the §101 analysis, recalling In re Bilski, and telling the person who had the question his or her opinion. Claims 2-6 depend on claim 1. Therefore, the rejection of claims 2-6 are rejected the same reason as the rejection of claim 1 set forth above. Conclusion 6. Any response to this action should be mailed to: Mail Stop_________ (Explanation, e.g., Amendment or After-final, etc.) Commissioner for Patents P.O. Box 1450 Alexandria, VA 22313-1450 Facsimile responses should be faxed to: (571) 273-8300 Hand-delivered responses should be brought to: Customer Service Window Randolph Building 401 Dulany Street Alexandria, VA 22313 Any inquiry concerning this communication or earlier communications from the examiner should be directed to Tuan H.
