Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Allowable Subject Matter
Claims 10 and 13 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: with respect to the allowable subject matter, none of the prior art either alone or in combination disclose or teach of the claimed combination of limitations to warrant a rejection under 35 USC 102 or 103.
Specifically, with respect to dependent claim 10, the prior art of Liu taken either singly or in combination with any other prior art fails to suggest such an optical imaging lens assembly comprising: “wherein ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the optical imaging lens assembly, and an effective semi-diameter DT11 of the object-side surface of the first lens and ImgH satisfy 2.3<10 x DT11/ImgH<2.8”.
Specifically, with respect to dependent claim 13, the prior art of Liu taken either singly or in combination with any other prior art fails to suggest such an optical imaging lens assembly comprising: “wherein SAG51 is an on-axis distance from an intersection point of an object-side surface of the fifth lens and the optical axis to an effective radius vertex of the object-side surface of the fifth lens, SAG52 is an on-axis distance from an intersection point of an image-side surface of the fifth lens and the optical axis to an effective radius vertex of the image-side surface of the fifth lens, and SAG51 and SAG52 satisfy 0.7< SAG52/SAG51 <0.9”.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Chen (20210116683) and Zhang (20200409117) are examples of a five lens optical assembly providing a lens system with high image quality.
