Office Action

§101
CTNF 18/198,648 CTNF 84342 DETAILED ACTION Claims 1-20 have been examined and are pending. Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 07-04-01 AIA 07-04 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 19 and 20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because the claims recite a “processor” and “logic.” Logic is known in the art as non-statutory software per se. The broadest reasonable interpretation of a “processor” includes hardware processors; software per se processors (as recited in Applicant’s specification at ¶ [0034]); or processors comprising a combination of hardware and software. Since the specification and claims do not expressly exclude software per se processors, the claimed “processor” may be interpreted as software per se, which does not fall into the four categories of patent eligible subject matter. To overcome this rejection, Applicant has several examples of statutory processor embodiments in the specification, including but not limited to a “processor set (including processing circuitry 120 and cache 121)”, ASICs, hardware processor, etc. which can be used to amend Claim 19’s processor. Allowable Subject Matter 12-151-07 AIA 07-97 12-51-07 Claim s 1-18 are allowed. The following is an examiner’s statement of reasons for indicating allowable subject matter: It must be recognized that any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning. But so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made, and does not include knowledge gleaned only from the applicant's disclosure, such a reconstruction is proper. See In re McLaughlin , 443 F.2d 1392, 170 USPQ 209 (CCPA 1971). Here, the limitations presented in the independent claims, taken together as a whole and as presented, cannot be rejected by the prior art of record without using a level of hindsight reasoning that is impermissible. Specifically, the closest prior-art reference US 2021/0248205 A1, either alone or in combination with CN 114281416 A; US 2021/0064675 A1 and Applicant-supplied Non-Patent Literature entitled “Finding and fixing duplicates in webpack with Inspectpack”, as well as those listed in Form PTO-892, fail to disclose all of the limitations required by the independent claims. 13-03 Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Interview Practice USPTO Automated Interview Request (AIR) The USPTO AIR is a new optional online interview scheduling tool that allows Applicants to request an interview with an Examiner for their pending patent application. The USPTO AIR form is available on our website at: http://www.uspto.gov/patent/laws-and-regulations/interview-practice . By submitting this type of interview request, the pending patent application will be in compliance with the written authorization requirement for Internet communication in accordance with MPEP §502.03. This authorization will be in effect until the Applicant provides a written withdrawal of authorization to the Examiner of record. If you have questions or need assistance with the USPTO AIR form or with interview practice at the USPTO, please contact an Interview Specialist at http://www.uspto.gov/patent/laws-and-regulations/interview-practice/interview-specialist or send an email to ExaminerInterviewPractice@USPTO.GOV . Examiner Notes: A) Prior to conducting any interview (whether using AIR or not), Applicant(s) must submit an agenda including the proposed date and time, all arguments in writing, and proposed claim amendments (if applicable). Any proposed amendments or arguments not presented in the agenda will only be heard by the Examiner, but because the Examiner will not have heard them in advance and been given an equitable opportunity to consider them, no decision will be rendered, nor agreement made. ALL AGENDAS MUST BE RECEIVED BY THE EXAMINER AT LEAST 24 HOURS PRIOR TO THE START OF THE INTERVIEW, OR THE PREVIOUS BUSINESS DAY, WHICHEVER IS LONGER, or the interview may have to be rescheduled. B) After-final interviews may be granted, but the agenda must be in compliance with MPEP 713.09 which limits the interview only to discussions of proposed amendments, or clarification for appeal. After-final interviews are not to be conducted for the purpose of rehashing previously made arguments. After seeing the agenda, Examiner will decide whether to grant or deny the interview. Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. See Form PTO-892 . Any inquiry concerning this communication or earlier communications from the examiner should be directed to RICHARD G KEEHN whose telephone number is (571)270-5007.
