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 .
DETAILED ACTION
This office action is responsive to the applicant's amendment submitted on 11/20/2025. Claims 1-2, 4-5, and 7-8 have been amended. Thus, claims 1-9 are currently pending in the instant application.
Claim Objections
Claims 1, 4 and 7 are objected to because of the following informalities:
In claims 1, lines 10-11, it is suggested that the limitation recites “the power signal from the power input sequentially passes through the first rectifier filter device, switching component, the transformer (T1), and the second rectifier filter device” should be changed to --a power signal from the power input sequentially passes through the first rectifier filter device, the switching component, the transformer (T1), and the second rectifier filter device-- to avoid antecedence basis.
In claim 4, line 10, and claim 7, line 12, it is suggested that the limitation recites “the power signal from the power input” should be changed to --a power signal from the power input-- to avoid antecedence basis.
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 1-9 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.
Regarding claims 1, 4 and 7, lines 10-13, the limitation recites “the power signal from the power input sequentially passes through the first rectifier filter device, the switching component, the transformer (T1), and the second rectifier filter device, and after passing through the transformer (T1), the power signal is also transmitted to the switching component passing through the feedback circuit and the power chip (U1)” is unclear and leaves the reader in doubt as to the meaning of the technical feature to which it refers. It is unclear that how the power signal from the power input sequentially passes through the first rectifier filter device, switching component, transformer T1, and the second rectifier filter device? And how does the power signal is also transmitted to the switching component passing through the feedback circuit and the power chip (U1)? Maybe via a loop or a path?
The claim fails to recite sufficiently definite structure, material or acts for achieving the functional result recited in the claim to reasonably apprise one of ordinary skill in the art of the scope of the claim.
Claims 2-3, 5-6, and 8-9 are depending on claims 1, 4, and 7, and are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph as the same reason as stated above.
Note: for compact prosecution purposes, the examiner interprets the claims above as best understood in the rejection below.

It would have been obvious to incorporate the conversion circuit as taught by Zhu into the lighting device as taught by Chen in order to allow the power signal sequentially passes through the first rectifier filter device, the switching component, the transformer, and the second rectifier filter device, and after passing through the transformer, the power signal also transmitted to the switching component through the feedback circuit and power chip. This can solve the bottleneck problem of present switch power supply working frequency is increased, at the same time, binding material selection, finally to achieve the goal reduces the product volume size, increasing power density. circuit adopts the modularized design and provide work to match the frequency selection function and is convenient for the using of the product (see abstract by Zhu).
Applicant is also reminded that the test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981).
Finally, applicant's arguments do not clearly point out the patentable novelty which he or she thinks the claims present in view of the state of the art disclosed by the references cited or the objections made. Further, they do not show how the amendments avoid such references or objections.
Therefore, the examiner still maintains rejection and make the office action as final.
Conclusion
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
