Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 2. A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 01/06/2026 has been entered. Response to Amendment 3. Receipt of Applicant’s Amendment filed on 01/06/2026 is acknowledged. The amendment includes the amending of claims 1, 6, and 11. Information Disclosure Statement 4. The information disclosure statement (IDS) submitted on 01/06/2026 has been received, entered into the record, and considered. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Objections 5. Claims 1, 6, and 11 are objected to because of the following informalities: The limitation “the clone request causing the remote node to record, prior to creation of the clone, an intent record identifying the clone and a delegation record that exclusively delegates modification authority for file to the local node during clone creation” is grammatically incoherent and should be replaced with “the clone request causing the remote node to record, prior to creation of the clone, an intent record identifying the clone and a delegation record that exclusively delegates modification authority on the file to the local node during clone creation”. Appropriate correction is required. Claims 2-5, 7-10, and 12-18 are objected to for incorporating the deficiencies of independent claims 1, 6, and 11 respectively. Claims 1, 6, and 11 are objected to because of the following informalities: The limitation “wherein the delegation record preventing any modifications to the file that would cause the file to no longer match a point in time at which the clone is created” is grammatically incoherent and should be replaced with “wherein the delegation record prevents any modifications to the file that would cause the file to no longer match a point in time at which the clone is created”. Appropriate correction is required. Claims 2-5, 7-10, and 12-18 are objected to for incorporating the deficiencies of independent claims 1, 6, and 11 respectively. Claim Rejections - 35 USC § 112 6. 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. 7. 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. 8. Claims 1, 6, and 11 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. Specifically, it is unclear as to how there can be no modifications to the file (See limitation “wherein the delegation record preventing any modifications to the file that would cause the file to no longer match a point in time at which the clone is created”) when the local node is granted exclusive modification authority (See earlier limitation of “the clone request causing the remote node to record, prior to creation of the clone, an intent record identifying the clone and a delegation record that exclusively delegates modification authority for file to the local node during clone creation”) on that file. Claims 2-5, 7-10, and 12-18 are rejected to for incorporating the deficiencies of independent claims 1, 6, and 11 respectively. Allowable Subject Matter 9. Claims 1, 6, and 11 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Specifically, although the prior art (See Bohle), clearly grants (and stores) delegation information for read/write requests on data, Martynov stores an intent record before creating a clone of a file, and Bharathy stores an exclusive lease lock during creation of a clone, the detailed claim language directed towards the storage before the creation of the clone of both the defined intent record and the defined delegation record in response to the received clone request is not found in the prior art in conjunction with the rest of the limitations of the independent claims. Claims 2-5, 7-10, and 12-18 are deemed allowable for depending on the deemed allowable subject matter of independent claims 1, 6, and 11 respectively. Conclusion 10. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. U.S. Patent 9,223,500, by Lemar et al., issued on 29 December 2015. The subject matter disclosed therein is pertinent to that of claims 1-18 (e.g., methods to clone files). Contact Information 11.
