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 .
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 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.
Status of the application
This office Action is in response to Applicant's Application filled on 03/20/2026. Claims 1-20 are pending for this examination.
Priority
Acknowledgment is made of applicant's claim for foreign priority under 35 U.S.C. 119(a)-(d). The certified copy has been filed on 01/22/2024.
Oath/Declaration
The oath or declaration filed on 12/04/2023 is acceptable.
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 10/26/2023 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement has been considered by the examiner.
Election/Restrictions
Applicant’s election, with traverse, group I, Species I (Fig 1): claims 1-10, in the “Response to Election / Restriction Filed” filed on 03/20/2026 is acknowledged. The traversal is on the ground(s) that device/method claims are mirror identical and Species I to species III are not directed to patentably distinct species and fails to demonstrate a serious search burden. Thus, Applicant requests that the restriction requirement be withdrawn.
Examiner like to note that, device and methods claims are not identical as indicated office action (12/31/2025) such as “at least one valley of the corrugated part of the clip so that the mold compound forms an outer surface of the semiconductor device with the at least two peaks of the corrugated part of the clip, at least part of the flat part of the clip, and the first lead frame surface of the lead frame are exposed”.
The species require a different field of search (e.g., searching different classes/subclasses or electronic resources or non-patent language, or deploying different search queries); and/or the prior art applicable to one species would not likely be applicable to another species; and/or the species are likely to raise different non-prior art issues under U.S.C. 101 and/or 35 U.S.C. 112, first paragraph.
Furthermore, the species and device/method require separate classification searches (i.e. H10W70/461 or H10W70/041 or H10W70/048 or H10W70/466 or H10W74/016 or H10W74/111 or H10W90/811 or H10W70/481 or H10W70/415 or H10W70/438) such as there are mutually exclusive features, as indicated in office action 07/22/2024 and these mutually exclusive features are categorized in the separate classes. Additionally, the species require different text searches.
The requirement is still deemed proper and is therefore made FINAL.
This office action considers claims 1-20 are thus pending for prosecution, of which, claims 11-20 are withdrawn, and claims 1-10 are examined on their merits.
