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 .
Election/Restrictions
2. Applicant's election with traverse of Group I, Species A1, in the reply filed on 08/10/2026 is acknowledged. The traversal is on the ground(s) that claim 26 requires all of the features of claim 1 and thus fall under a single inventive concept. This is found persuasive and, thus claims 26-28 (Group II) will be rejoined onto Group I for further consideration.
With respect to Applicant’s traversal of the restriction requirement, Applicant’s arguments are based on the presently amended claims having a technical feature not taught by the references cited in the restriction requirement set forth in the office action mailed 06/10/2026. However, the restriction requirement was properly made with respect to the claims presented at the time of the previous office action (i.e., the claims as originally presented) and Applicant has not presented any arguments directed to the original claims. Also, even with respect to the newly amended claims, the amended claims do not make a contribution over the prior art (i.e., Species A1 and A2 still lack the same or corresponding special technical feature) because the groups do not make a contribution over the prior art, namely Liu (CN 209324703 U, cited in prior office action) as set forth below.
Liu teaches a sterilization and disinfection lamp (fan assembly 2, Fig. 1), comprising:
a housing (walls of fan assembly 2, Fig. 1), wherein the housing is provided with a sterilization cavity (annular seat 24, Fig. 1), and an air inlet (lower mesh 25, Fig. 1) and an air outlet (upper mesh 23, Fig. 1), which communicate with the sterilization cavity (air sucked in by fan blade 21, Fig. 1);
a light-emitting assembly (light emitter assembly 5, Fig. 1), which is mounted on an outer surface of the housing (mounted on outer surface of annular seat 24 via frame 3, Fig. 1); and
a plasma generator (7, Fig. 1), at least part of which is accommodated in the sterilization cavity and generates positive ions and negative ions (p.2, last paragraph of English translation), wherein at least some positive ions and negative ions are combined in the sterilization cavity to sterilize and disinfect air flowing into the sterilization cavity through the air inlet, and at least some other positive ions and negative ions flow into the outside environment through the air outlet and are combined, so as to sterilize and disinfect the air of the outside environment (the recombination of the generated positive and negative ions in both the cavity and the outside environment is an intrinsic result of plasma generation encountering the flowing airstream, and thus, because the claimed structure is identical, the recombination to sterilize the air is a downstream result from the plasma generator 7, Fig. 1, see p.3, 6-7th paragraphs of English translation also demonstrating the recombination effect both in the air in the annular seat and the expelled air);
the air outlet is provided with an air outlet grid (mesh cover 23 is a grid because a mesh is a grid, Fig. 1), an air guide surface of the air outlet grid is obliquely arranged relative to a horizontal plane (the surface of the mesh cover 23 is slanted with respect to the horizontal plane relative to the drawing, Fig. 1), and the air guide surface obliquely extends downward along an air outlet direction (the surface slants downward along the mesh cover 23, Fig. 1).
Claims 4-5 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 08/10/2026.
Drawings
3. The drawings are objected to because the lines and text correlating to specific parts of the drawings are illegible (i.e., too blurry). Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Claim Objections
4. Claim 3 is objected to because of the following informalities: in lines 3-4, “one or a plurality of air inlets are provided” should be corrected to “where a plurality of air inlets are provided”.
Claim 6 is objected to because of the following informalities: in lines 3-4, “one or a plurality of air outlets are provided” should be corrected to “where one or a plurality of air outlets are provided”.
Appropriate correction is required.

5. 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:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
6. Claims 1-3, 6-7, 9, 22-24, and 26-28 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Liu (CN 209324703 U).

Claim Rejections - 35 USC § 103
7. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
8. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Liu (CN 209324703 U) as applied to claim 1 above, and further in view of Takasahara et al. (US 20170274113 A1).
Regarding claim 8, Liu teaches wherein the sterilization and disinfection lamp further comprises a fan (fan 21, Fig. 1), the air inlet (lower mesh 25, Fig. 1) is arranged on the bottom surface of the housing (bottom walls of annular seat 24, Fig. 1), the air outlet is arranged on the side surface of the housing (mesh cover 23 is on a side surface of the walls of annular seat 24, Fig. 1), the fan is used for blowing the positive ions and the negative ions into the outside environment from the air outlet (p.4, 7th paragraph of English translation), the fan (21, Fig. 1) is directly opposite to the air inlet (lower mesh 25, Fig. 1) so that the air from the air inlet uniformly flows to the air outlet (mesh cover 23, Fig. 1) through the fan (p.4, 7th paragraph of English translation), and an emission head assembly of the plasma generator (the head of plasma generator 7 that the ions are generated directly on, Fig. 1) is arranged close to the air outlet relative to the fan (mesh cover 23 is downstream of the plasma generator 7, Fig. 1).
Liu fails to teach wherein the fan is a centrifugal fan.
Takasahara teaches a ceiling-mounted plasma generating assembly (Fig. 2) for the purpose of removing pathogens in the air ([0047]), further citing a centrifugal fan (33, Fig. 2) to generate a circulating airstream into and out of the ion generator ([0042]).
Liu and Takasahara are both considered to be analogous to the claimed invention because they are in the same field of wall-mounted airstream-circulating plasma generators.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to substitute the fan of Liu with the centrifugal fan of Takasahara, because the substitution of this feature yields the predictable result of generating a circulating airstream into and out of the ion generator (Takasahara, 0042]) with a reasonable expectation of success.
9. Claims 10-11 are rejected under 35 U.S.C. 103 as being unpatentable over Liu (CN 209324703 U) as applied to claim 9 above, and further in view of Robert (US 20160367712 A1).
Regarding claim 10, Liu teaches wherein the plasma generator (7, Fig. 1) is mounted on the housing (annular seat 24, Fig. 1); having an emission head assembly (circuitry of plasma generator 7 connected to control device 72, Fig. 3, also shown in drawing below), which is arranged on a cavity wall of the sterilization cavity (annular seat 24, Fig. 1), at least an emission head of the emission head assembly is arranged inside the air guide duct (see drawing below), and at least one emission head assembly is arranged inside at least one air guide duct (see drawing below).

Liu fails to teach wherein the plasma generator comprises: a plasma flyback transformer, wherein the plasma flyback transformer is connected to the emission head assembly.
Robert teaches a sanitizing assembly emitting ions/plasma to sanitize an airstream (Fig. 8) having a plasma generator (Fig. 21) comprising an emission head (electrode 80, Fig. 8 and 21) and an emission head assembly (circuitry of Fig. 21) further comprising dual flyback transformers (140,142, Fig. 21) in order to improve the output of ions from the electrode ([0142]).
Liu and Robert are both considered to be analogous to the claimed invention because they are in the same field of plasma generators for airstream disinfection.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the plasma generator of Liu by incorporating a dual-flyback transformer circuit as taught by Robert, because doing so improves the output of ions from the electrode (Robert, [0142]) with a reasonable expectation of success.
Regarding claim 11, modified Liu fails to teach wherein a plurality of emission head assemblies are provided;
the plurality of emission head assemblies are arranged at intervals along a circumferential direction of the cavity wall of the sterilization cavity, and the emission head of each emission head assembly is exposed in the sterilization cavity.
However, it would have been obvious to duplicate the single plasma generator mounted in the cavity wall of the sterilization cavity of modified Liu to now be a plurality of plasma generators, thus yielding the predictable result of increased plasma generation, because “mere duplication of parts has no patentable significance unless a new and unexpected result is produced” (see MPEP 2144.04(VI)(B)).
PNG

With this modification, the plurality of emission head assemblies (duplicated emission head assemblies, see drawing above) are arranged at intervals along a circumferential direction of the cavity wall of the sterilization cavity (a duplicated plasma generator would be at a set distance from the original plasma generator 7, Fig. 1), and the emission head of each emission head assembly is exposed in the sterilization cavity (the original plasma generator emission head is exposed in the sterilization cavity, so the duplicated one should as well).
10. Claims 17-18 are rejected under 35 U.S.C. 103 as being unpatentable over Liu (CN 209324703 U) as applied to claim 1 above, and further in view of Machi et al. (US 20160031708 A1).
Regarding claim 17, Liu teaches the light-emitting assembly (sterilizing light emitting assemblies 52, Fig. 1, shown in claim 1 rejection drawing above) and the bottom surface of the housing (bottom surface of annular seat 24, Fig. 1), but fails to teach wherein the sterilization and disinfection lamp further comprises a radiator;
the radiator is padded between the light-emitting assembly and the bottom surface of the housing.
Machi teaches a plasma generator for the disinfection of air (100B, Fig. 5), further teaching a cooling module (210, Fig. 5) and heat radiating fins (220, Fig. 5) attached to one of the plasma generating electrodes (111, Fig. 5) in order to cool the electrode and dissipate heat ([0055-0056]).
Liu and Machi are both considered to be analogous to the claimed invention because they are in the same field of plasma generators for airstream disinfection.
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the plasma generator of Liu by incorporating a cooling module and heat radiating fins adjacent to the plasma generating electrode as taught by Machi, because doing so would cool the plasma generating electrode and dissipate heat (Machi, [0055-0056]) with a reasonable expectation of success.
With this modification, the radiator (Machi, cooling module 210 and fins 220, Fig. 5) is padded between the light-emitting assembly and the bottom surface of the housing because the plasma generator (Liu, 7, Fig. 1) adjacent to the radiator is between the bottom surface of the housing (Liu, bottom surface of annular seat 24, Fig. 1) and the light-emitting assembly (sterilizing light emitting assemblies 52, Fig. 1, shown in claim 1 rejection drawing above).
Regarding claim 18, modified Liu teaches wherein the sterilization and disinfection lamp further comprises a fan (21, Fig. 1).
The limitation of “the gas temperature inside the housing may be less than or equal to 50° by arranging the radiator and adjusting the air velocity and air volume of the fan” are directed to the function of the apparatus and/or the manner of operating the apparatus. All the structural limitations of the claim has been disclosed by the Liu/Machi combination and the apparatus of the Liu/Machi combination is capable of having a gas temperature inside the housing less than or equal to 50° by arranging the radiator and adjusting the air velocity and air volume of the fan. As such, it is deemed that the claimed apparatus is not differentiated from the applicant' s invention (see MPEP §2114).
NOTE: this is a recitation of intended use / functional language, and so long as the prior art structure reads on the instant claimed structure, this limitation would be met because the same structure would be capable of the same function; in this case, the instant combination teaches a radiator, fan, and a housing, to which the ambient environment could already be less than equal to 50° (Celsius or Fahrenheit), and with the fan running at a predetermined speed and the radiator being in the housing, the temperature of the gas entering the housing (which directly comes from the ambient environment) could also be under 50°.
Per MPEP 2114,II, claims cover what a device is, not what a device does. A claim containing a recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus if the prior art apparatus teaches all the structural limitations of the claim.
