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 . The amendment filed on 03/03/2026 has been entered. Applicant amended claims 1-20 in the amendment. Claims 1-20 remain pending. Response to Arguments Applicant’s arguments with respect to claims 1-20 filed on 03/03/2026 have been considered but they are deemed to be moot in view of new grounds of rejection. Claim Objections Claim 19 is objected to because of the following informalities: Claim 19, line 16, “each respective data element” should read “each respective data element from among the plurality of the data elements”; Claim 19, line 21, “the respective data element” should read “each respective data element”; Appropriate correction is required. 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 1-20 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 recites the limitation "the assigned metadata" in line 16. There is insufficient antecedent basis for this limitation in the claim. Same rejection applies to claims 10 and 19. Regarding claim 12, claim limitation recite “the data element” in line 3, which renders the claim vague and indefinite. It is unclear whether “the data element” is referring to “each respective data element” in claim 10, line 9, or to “at least a first data element” in claim 12, line 1-2, or to different/distinct data element. Claim 19 recites the limitation “the assigned metadata” in line 19. There is insufficient antecedent basis for this limitation in the claim. Claim 19 recites the limitation “the metadata” in line 20. There is insufficient antecedent basis for this limitation in the claim. All dependent claims are rejected as having the same deficiencies as the claims they depend from. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Prakash et al. (US 11,620,407 B2).

Kacker et al. (US 2024/0265130 A1). Receive data access event relates to a data element, determine whether the data element is a personally identifiable information (PII) data element, predict a PII protection policy using a machine learning model, and apply the PII protection policy to the PII data element.
