Abstract

An electric toy includes a multi-stage synchronous driving mechanism. Via engagement between a sun gear and planetary gears, all execution units are ensured to rotate synchronously at a preset proportion, improving consistency and accuracy of motion. Motor torque is transferred to the sun gear through a gear transmission component, and a single sun gear drives multiple planetary gears at once, so the execution units rotate relative to a support without multiple transmission structures or shafts — giving structural flexibility and lower manufacturing cost.

Claim structure (14 claims total)

Strictly by dependency, claim 1 is the only formal independent claim; claims 2, 4, 5, 8, 9, 10 are dependent mechanism claims, and claims 3, 6, 7, 11, 12, 13, 14 are "electric toy" product claims that each incorporate the mechanism of an earlier claim and add light-emitting parts (a separate statutory category but formally dependent). Overview:

• Claim 1 (independent — the driving mechanism): A housing; a motor on the housing; a gear transmission component driven by the motor; and a multi-stage execution component having a support, a sun gear, multiple planetary gears rotatably on the support, and execution units each connected one-to-one to a planetary gear. The sun gear is driven by the gear transmission and meshes with each planetary gear, so the motor rotates the sun gear → planet gears → execution units relative to the housing. Each execution unit is an insertion post + stop plate + free arm connected in sequence; the planetary gear sleeves onto the insertion post, the free arm penetrates the support, and the stop plate movably abuts the support. It also requires a stop post (between insertion post and stop plate) and a matching stop slot on the planetary gear.

• Claim 2: Each free arm has at least one "torsional position" (a twisted segment creating a twisting visual effect during rotation).

• Claim 3 (electric toy): The mechanism of claim 2 plus light-emitting parts located in the housing and correspondingly disposed in the support.

• Claim 4: Assembly-alignment feature — an alignment notch at the same position on every stop slot, and an alignment protrusion on each stop post (same set positions/orientations) detachably inserted into the notch, preventing assembly-angle errors.

• Claim 5: Equally spaced alignment marks around the sun gear's periphery, in one-to-one correspondence with the alignment protrusions, to pre-align initial positions/rotation angles.

• Claims 6 & 7 (electric toy): Mechanism of claims 5 and 4, respectively, plus light-emitting parts.

• Claim 8: Two-piece support structure — a base (installation hole + through holes) connected to an upper cover (connecting hole + avoidance holes), defining an accommodation interval housing the sun gear and planetary gears; free arms pass through the through holes, insertion posts align with avoidance holes, and part of the sun gear is exposed at the connecting hole.

• Claim 9: Torque-coupling detail — a torque gear with a torque transmission post; a central post on the sun gear having a torque slot; the post detachably inserts into the slot so gear rotation drives the sun gear.

• Claim 10: Motor mounting on an installation rack; a worm driven by the motor and a train of transmission gears engaged in sequence (one with the worm); when the rack is aligned/assembled with the support, another transmission gear engages the torque gear.

• Claims 11–14 (electric toy): Mechanism of claims 10, 9, 8, and 1, respectively, each plus light-emitting parts in the housing/support.

Plain-language gist

One motor, through a worm-and-gear reduction train, spins a central sun gear. Several planet gears around it all mesh with that one sun gear, so they turn together in lockstep; each planet gear carries a decorative "execution unit" (an arm that pokes through the toy's support and visibly twists as it rotates). The alignment notches/protrusions and sun-gear alignment marks are manufacturing/assembly aids ensuring every arm starts at the correct angle so the arms don't collide. The "electric toy" claims simply package this mechanism with LEDs for visual effect.

Uncertainty notes

• Assignee: Google Patents shows only "Individual"; I could not confirm a USPTO Assignment search showing any transfer (reporting it as an individual assignment appears most accurate).
• CAFC 2026 docket search: A search for "12465872" / "12,465,872" in CAFC 2026 dockets returned no results, and no appeal or post-grant proceeding citing this patent was found. As of the search date I have no indication of CAFC litigation involving this patent — but absence from search results is not conclusive proof of no proceeding.
• Number-matching caution: Search results surfaced unrelated items sharing digits (e.g., Japanese utility model JP12465872U from 1972; U.S. Patent No. 12,692,476 in a Lineage Cell press release). These are not the target patent and were excluded per the literal-ID rule.

I'll search several litigation databases and sources for cases involving U.S. Patent No. 12,465,872.

Initial searches found only unrelated patents with partial number matches (e.g., 11,772,872; 9,935,872). Let me run additional targeted searches.

Litigation Search Results — U.S. Patent No. 12,465,872 (US12465872B2)

No known litigation involving U.S. Patent No. 12,465,872 was found.

What I searched

I ran targeted searches across general web, litigation aggregators, and docket-content sources for:

• "12465872" patent litigation
• "12,465,872" patent lawsuit / "12,465,872 B2" case
• "US12465872" / "US 12465872"
• Inventor-based search ("Shaoqing Lin" patent lawsuit OR litigation OR complaint)
• Title-based search ("Multi-stage synchronous driving mechanism" infringement OR lawsuit)
• Site-restricted search of unifiedpatents.com for the patent number

What the searches returned (and why it is excluded)

Every "hit" was an unrelated patent or proceeding that merely shares trailing digits — none concerns this patent:

Assessment

• U.S. Patent No. 12,465,872 issued November 11, 2025 — roughly five months before today's date (April 26, 2026). The patent is very young, which is consistent with no litigation having yet accrued.
• The sole inventor/assignee is listed as an individual (Shaoqing LIN) in the toy space; no corporate NPE/assertion entity activity surfaced.
• As of the search date, I found no district-court complaint, ITC investigation, CAFC appeal, IPR/PGR petition, or any other proceeding naming US 12,465,872.
• Caveat (stated plainly): Absence from web/aggregator search results is not conclusive proof that no proceeding exists. PACER and the USPTO Patent Center/PTAB filing systems are the authoritative sources, and my searches could not directly query PACER's full-text docket database. If a complaint was filed under seal, very recently, or in a system not indexed by the searched engines, it could evade detection.

Bottom line: Based on all information available to me, no litigation is known involving U.S. Patent No. 12,465,872 as of April 26, 2026. If you need definitive confirmation, I recommend direct PACER queries (party name "Lin, Shaoqing" or patent number 12,465,872) and a USPTO PTAB search for AIA proceedings.

The two searches surfaced only unrelated material (a UK company registration number 12465872, and an unrelated PGR2026-00072 against Anagen LLC). Let me run a few more targeted checks before concluding.

Proceedings overview

There are zero AIA trial proceedings (IPR, PGR, or CBM) on file against U.S. Patent No. 12,465,872. The USPTO Open Data Portal ingest reflected in the structured "PTAB proceedings on file" block reports no AIA trial proceedings for this patent, and independent web searches (run 2026-09-09 for the patent number, inventor "Shaoqing LIN," and the title) surfaced no petition, no institution decision, and no Final Written Decision naming this patent. Every search hit was an unrelated matter sharing digits or keywords (e.g., UK Companies House number 12465872; PGR2026-00072 against Anagen LLC; PGR2026-00030 Hyundai v. Germ Dome; IPR2026-00470 by Zoom). The defensive posture this gives a defendant is a clean slate: no claim of 12,465,872 has been tested, narrowed, or canceled at the PTAB, and no estoppel has been generated against any would-be petitioner — but equally, there is no Board precedent hardening the patent.

Proceeding-by-proceeding review

No proceedings on file

• Type: N/A — no Inter Partes Review, Post-Grant Review, or Covered Business Method petition has been filed.
• Filed: N/A
• Status: N/A — the USPTO ODP block is verbatim: "The USPTO ODP API returns no AIA trial proceedings for this patent as of the most recent ingest." Plain-English gloss: the PTAB's own docketing feed shows nothing.
• Judge panel: N/A
• Petition grounds: N/A
• Institution decision: N/A
• Final Written Decision: None exists.
• Settlement / termination: N/A
• Appeal: N/A
• Defensive value: With no PTAB record, a defendant facing assertion of 12,465,872 cannot cite any claim cancellation or Board claim construction as a litigation lever. The patent is untested in every sense relevant to AIA trial practice.

Strategic summary

Claim status: ALL CLAIMS UNTESTED. U.S. Patent No. 12,465,872 issued 2025-11-11 with 14 claims — claim 1 (the only formal independent mechanism claim), dependent mechanism claims 2, 4, 5, 8, 9, 10, and dependent "electric toy" product claims 3, 6, 7, 11, 12, 13, 14. None has been challenged in an AIA proceeding, so there are no canceled claims and no sustained claims in the PTAB sense. The entire patent remains prima facie valid and enforceable; every claim is effectively in the "untested" bucket.

Estoppel landscape: a blank slate, which cuts both ways. Because no IPR/PGR has reached a final written decision, 35 U.S.C. § 315(e)(2) estoppel binds no one. A defendant sued today faces no statutory bar to raising any § 102/§ 103 ground based on patents or printed publications, and — because the patent is young (priority date 2024-11-15, CN utility model CN223404405U; U.S. filing 2025-05-28) — it is ineligible for PGR by a defendant who is not first sued within nine months of grant only in the sense that the nine-month PGR window (35 U.S.C. § 321(c)) closed on 2026-08-11 (nine months after 2025-11-11 grant). That window has now passed, so IPR is the only AIA vehicle available going forward. Note also that an IPR petitioner must overcome the § 102/§ 103 prior-art horizon: the earliest priority date is 2024-11-15, so only art predating that date qualifies, and a diligent search should target the crowded toy-gearing space (sun-gear/planet-gear toy drives, worm-reduction toy mechanisms, and motorized spinning/optical toys) — the art classes the examiner already cited (A63H29/22, A63H33/22, H02K7/116).

Pattern signals: none. No repeat petitioner exists because no petition exists. The patent owner (sole inventor Shaoqing LIN, an individual) has never appeared at the PTAB in any capacity on this patent. No defensive aggregator (e.g., Unified Patents) has challenged it, and no district-court litigation, CAFC appeal, or ITC matter naming the patent was found in prior analysis. The one post-grant signal on the record is benign: the examiner's own "Cited By" entry, US20260069995A1 ("Interlocking toy," Yao Dong, filed 2025-09-10), which merely cites 12,465,872 as prior art in a later application — not a proceeding. The absence of PTAB activity at roughly ten months post-issue is unremarkable: this is an individual-owned consumer-toy patent with no visible assertion campaign, and such patents typically attract IPRs only after (or in anticipation of) district-court enforcement.

Recommended next steps

1. Because no PTAB activity exists, say so plainly — and use the absence as a diligence trigger, not a comfort blanket. The lack of a petition tells you the patent has not been meaningfully monetized or litigated yet. If a demand letter citing 12,465,872 is now on your desk, treat that as the event most likely to precede an IPR filing — by you or by a co-defendant.
2. Before filing anything, run the authoritative docket checks directly. Web and ODP feeds are not conclusive. Query (a) USPTO PTAB E2E / the PTAB API for "12,465,872" and "US12465872B2," (b) the USPTO Patent Center for the file wrapper, and (c) PACER for any district-court complaint naming "Shaoqing LIN" or the patent. Also check the USPTO Assignment database to confirm whether the "Individual" ownership has changed — a transfer to an assertion entity would change the risk calculus.
3. If you decide to attack, the vehicle is IPR, and the clock math matters. The PGR window closed 2026-08-11, so only IPR remains. An IPR petition must be filed within one year of being served with a complaint (35 U.S.C. § 315(b)) — if litigation is imminent or pending, that one-year bar is your hard deadline. Target claim 1 (the sole independent claim) plus the dependent claims that track your accused product: claims 8–10 (support structure, torque coupling, worm/gear train) are the mechanically substantive ones most likely to matter in an infringement analysis; claims 2, 4, 5 add the torsional-arm and alignment-feature limitations.
4. If you are in litigation and choose not to petition, the PTAB record remains empty, so your invalidity case must be made in district court under the clear-and-convincing standard, with no § 315(e) estoppel constraint and no Board claim construction to bind you — the conventional trade-off, with no prior PTAB activity to color the court's view either way.

Caveat, stated plainly: no proceeding means no FWD to quote and no Board reasoning to cite. This report's "no activity" conclusion rests on the USPTO ODP structured data and web searches; it is not a certified PTAB docket search, and a petition filed under seal or in the last several weeks could evade both. If you need a dispositive answer before making a filing decision, run the PTAB E2E and PACER queries in step 2 directly.

Inventors

• Shaoqing LIN — sole named inventor on US12465872B2 and on the priority document (Chinese utility model CN202422799628.4U → CN223404405U, filed 2024-11-15).
• Employer at filing: not determinable. No corporate assignee appears anywhere on the record; Google Patents lists the assignee as "Individual." No recorded employment-side assignment naming a company was found, so there is no way to tie LIN to an employer from public ownership records. Justia's inventor page lists LIN's U.S. filings but discloses no affiliation.
• Pattern note: single inventor, individual ownership, and a small, two-member family (CN utility model + one U.S. application). There is no pattern of inventor flight from an operating assignee because no operating assignee ever appears on the record.

Original assignee

• Google Patents shows both "Original Assignee" and "Current Assignee" as "Individual" (Shaoqing LIN). This is the default when no assignment from the inventor to a separate entity is recorded — i.e., the inventor owns the patent directly.
• Product embodiment: none identified. There is no evidence LIN (or any entity) ships a product embodying the claims; the patent is in the consumer-toy/gearing space but no commercial tie was found.
• Line of business: N/A — no operating company in the chain.
• Current status: the inventor/owner is presumably an individual; no dissolution, bankruptcy, or acquisition event applies or was found.

Assignment timeline

No recorded assignments were found for US 12465872.

Searches of the USPTO assignment indexes via web-accessible sources (Google Patents legal-events feed, Patents-Review/Justia mirrors, and targeted queries for the patent number and inventor name) surfaced zero assignment records — no reel/frame entries, no conveyances of any type. The Google Patents legal-events block for this patent contains only prosecution and fee events (FEPP entity-status settings dated 2025-05-28 and 2025-06-09; STPP examination/allowance events through 2025-09-30; issue-fee events 2025-10-15/16; STCF "PATENTED CASE" on 2025-10-29). There is no ATSS-style assignment event of any kind.

I could not directly query assignmentcenter.uspto.gov's internal database from this environment, so I cannot certify the Assignment Center is empty with 100% certainty — but every public index that mirrors USPTO assignment data shows no transfer, and the patent's own "Individual" assignee designation is consistent with the inventor simply owning the patent, with no recorded post-filing assignment. If you need a dispositive check, run the patent number (12,465,872 / US12465872B2) and the inventor name (LIN, Shaoqing) directly at https://assignmentcenter.uspto.gov/.

That absence is itself the finding: the original assignee (the inventor) still owns the patent.

NPE / troll-pattern signals

1. Shell-entity transfer — not present. No transfer to any LLC, "IP Holdings" entity, or registered-agent address exists on the record. The patent never left the inventor's name.
2. Known asserter in the chain — not present. No assignee other than the individual inventor appears; none of the tracked NPE names (Acacia, Marathon, IV, Wi-LAN, Conversant, Round Rock, MPHJ, Spangenberg entities, etc.) appears anywhere in the chain.
3. Repeat correspondent across the chain — not present / N/A. With zero recorded assignments, there is no correspondent of record on any conveyance to analyze. (No attorney name can be flagged because no reel/frame exists.)
4. Cascading transfers — not present. There are no consecutive assignments through chained LLCs; there are no assignments at all.
5. Pre-litigation transfer — not present. Prior analysis found no infringement suit naming this patent, and there is no assignment dated within six months of any suit (or at any date) to evaluate.
6. Bankruptcy fire-sale — not present. The owner is an individual with no bankruptcy event on the public record and no corporate debtor involved.
7. Privateering — not present. No operating company transferred the patent to an NPE; no SEC filings or EFF/Patent Progress coverage exist because no public company is involved.
8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at RPX, AST, LOT, Unified Patents, or OIN; it terminates at the individual inventor.

Verdict

Insufficient data — more precisely, a clean-record finding: the patent has no recorded assignments at all, so there is no chain to analyze and no NPE pattern of any kind is present.

The ownership record begins and ends with sole inventor Shaoqing LIN ("Individual" per Google Patents), consistent with no conveyance having ever been recorded; the patent issued 2025-11-11 and has generated no litigation, no PTAB challenge, and no assignment activity in the roughly ten months since grant. While I could not query the USPTO Assignment Center's internal database directly and cannot certify a completely empty docket, every accessible index corroborates inventor ownership — and an individual-owned, unlitigated, unassigned toy patent is the opposite of the typical NPE profile.

Prior-Art Analysis — U.S. Patent No. 12,465,872 (US12465872B2)

Scope, method, and ground rules

Target patent: US12465872B2 — "Multi-stage synchronous driving mechanism and electric toy," inventor Shaoqing LIN; U.S. application 19/221,405 filed 2025-05-28; priority date 2024-11-15 (Chinese utility model CN202422799628.4U → CN223404405U); granted 2025-11-11.

Search note. I could not directly query the USPTO's full-text search or Patent Center from this environment. I verified the target patent and its citation list through the Google Patents record for US12465872B2 (fetched 2026-09-09), which mirrors the USPTO front-page data. All 14 references listed below are the citations appearing on that record (each marked "*" — cited by examiner). Per the literal-ID rule, I excluded look-alike documents (e.g., Japanese utility model JP12465872U) and confirm that nothing below is a similar-number artifact — all 14 items are the actual citations on US12465872B2.

Statutory frame. Because the effective filing date is 2024-11-15 (post-AIA), 35 U.S.C. § 102(a)(1) and (a)(2) govern. All 14 cited references were patented/published and effectively filed before 2024-11-15, so each qualifies as § 102 prior art. That is the threshold question, however. Anticipation also requires that a single reference disclose each and every limitation of a claim, expressly or inherently. I therefore give, per reference, (i) the full citation, (ii) dates, (iii) description, and (iv) the claims whose limitations the reference most closely overlaps — plus a candid statement of which limitations are missing, because a reference that omits a single claim element cannot "potentially anticipate" under § 102 as a matter of law.

For quick reference, the claims are: claim 1 (sole independent — motor + gear transmission + sun gear meshing plural planet gears, each planet gear one-to-one with an execution unit made of insertion post / stop plate / free arm, with a stop post and matching stop slot on the planet gear); claims 2, 4, 5 (torsional position on the free arm; alignment notch/protrusion; sun-gear alignment marks); claims 8–10 (base/upper-cover support; torque-gear/torque-slot coupling; worm + transmission-gear train on an installation rack); claims 3, 6, 7, 11–14 ("electric toy" product claims adding light-emitting parts).

Confidence tags. References 1–5 below are described from actual retrieved text of the patents. For references 6–14, my session's searches were truncated before I could retrieve full texts; their descriptions rest on the bibliographic record (titles, assignees, dates) plus general knowledge, and I flag each accordingly. Where I could not verify disclosure details, I say so rather than inventing content.

Reference-by-reference analysis

1. US3449858A — "Toy spinning top"

• Citation: Balleis, Peter (assignee Lorenz Bolz GmbH & Co.); U.S. Patent No. 3,449,858; filed 1966-11-19; granted 1969-06-17.
• Description (verified from text): A hand-spun toy top. A body rotation drives a reduction gear, which turns a figure-supporting disk 17 located above a stationary disk 12. A central gear wheel on the disk meshes with several gear wheels 19–23 rotatably mounted in the disk; each gear wheel's shaft carries a colored toy figure (a ball, a multicolored umbrella, intersecting rings, toy vehicles). Rotation of the central gear rotates all the surrounding figure-carrying gears, so multiple figures move synchronously without colliding — functionally the same "one central gear drives several figure-carrying gears on a shared support" concept as the target patent.
• Closest claims: Claim 1's core concept (a central sun gear engaging a plurality of surrounding gears that carry rotating decorative members on a support).
• § 102 anticipation assessment: Does not fully anticipate claim 1. Missing: an electric motor disposed on a housing (drive is a manually spun body); a gear transmission driven by a motor; the specific execution-unit structure (insertion post sleeved by the planet gear, free arm penetrating the support, stop plate movably abutting the support, stop post + stop slot on the planet gear); and all dependent-claim features (torsional position, alignment features, base/upper-cover, torque gear, worm). This is, however, the single closest cited reference to the claimed concept and the strongest § 103 foundation reference against claim 1.

2. US3510949A — "Magnetic geometric pattern-producing device and toy"

• Citation: Christy, Alexander C.; U.S. Patent No. 3,510,949; filed 1968-12-23; granted 1970-05-12.
• Description (verified from text): A manually cranked amusement device in which a gear 72 rotates a revolving gear base 80 carrying planetary gears 84 on stub shafts 86. The planet gears mesh with a sun gear 66, and each planet gear carries an eccentrically mounted drive magnet that magnetically propels an inscribing figure across a paper sheet to trace geometric patterns. The sun/planet tooth counts are deliberately non-multiple so figures trace non-identical, non-colliding patterns.
• Closest claims: Claim 1's sun-gear/plural-planet-gear engagement concept; claims 4–5's anti-collision/alignment rationale (the reference deliberately staggers planet-gear tooth counts and orbits to prevent figure collisions).
• § 102 anticipation assessment: Does not fully anticipate claim 1. Missing: motor (hand crank), motor-driven gear transmission, and every execution-unit structural limitation (insertion post/stop plate/free arm/stop post/stop slot). Also no light-emitting parts for the toy claims. Relevant mainly as § 103 art on sun/planet gearing in toys.

3. US4629440A — "Animated toy"

• Citation: Mattel, Inc. (inventor Michael T. [per record]); U.S. Patent No. 4,629,440; filed 1985-07-08; granted 1986-12-16.
• Description (verified from text): A motorized toy shaped as an insect. A motor inside the hollow body drives, through a gear train, rotating hubs/elements on opposite sides of the body; multiple leg members are coupled to the rotating elements (ball-and-socket connections, cam-and-follower drives) so the legs move in coordinated, phased motion simulating walking.
• Closest claims: Claim 1's elements of a motor disposed in/on a housing and a gear transmission driving plural coordinated moving members.
• § 102 anticipation assessment: Does not fully anticipate claim 1. No sun gear meshing a plurality of planetary gears; no one-to-one execution units with insertion post/stop plate/free arm; no stop post/slot. Its value is as § 103 art showing a motor + gear train driving plural toy members synchronously — the power-train half of the claimed combination.

4. US4648487A — "Drive wheel equipped with power spring"

• Citation: Kabushiki Kaisha Bandai (inventor Shigeo Kimura); U.S. Patent No. 4,648,487; JP priority 1985-03-14 (JP60-51414); filed in U.S. 1985-06-14; granted 1987-03-10.
• Description (verified from text): A spring-powered drive wheel for a toy vehicle. A central sun gear 25 is rotatably mounted in the wheel casing; a power spring winds through a gear train containing planetary gears 29 and 33 and shift gears; spring release rotates the sun gear and drives the vehicle through the planet-gear release train. Sun gear + planetary gear trains are central to the design.
• Closest claims: Claim 1's sun-gear/planetary-gear gearing vocabulary (the reference uses the literal terms "sun gear" and "planetary gear").
• § 102 anticipation assessment: Does not fully anticipate claim 1. Power source is a spring, not a motor on a housing; gears drive a wheel/casing rather than execution units with free arms; no insertion post/stop plate/stop-slot structure. § 103 value only.

5. US6022263A — "Mechanical toy figures"

• Citation: LCD International, L.L.C. (inventors Dexter C. T. Liu, Douglas Melville, Jr.); U.S. Patent No. 6,022,263; filed 1998-03-20; granted 2000-02-08.
• Description (verified from text): A mechanical doll in which a spring-biased upper torso rotates relative to a lower torso. A fixed central drive gear 64 (described in the specification as acting like a "sun gear") engages two driven gears 66A/66B (described as acting like "planetary gears") mounted on arm shafts 29A/29B; as the torso rotates, the driven gears "roll around the drive gear" and rotate both arms in opposite directions, while a cam/link mechanism moves the head. Each arm shaft carries stop plates 79A/79B, and the arm connective portions are sandwiched between the stop plate and the shoulder to form a slip clutch. The specification expressly analogizes the gear train to "a planetary gear train, with two planetary gears being driven by a sun gear."
• Closest claims: Claim 1's one-to-one connection of driven (planet) gears to movable members (arms), and the stop-plate retention concept (stop plates 79A/79B on the arm shafts); claim 2's multi-segment articulated arm concept (though not a "torsional position").
• § 102 anticipation assessment: Does not fully anticipate claim 1. The drive is a user-twist/spring system rotating the torso relative to a fixed gear — not a motor driving the sun gear through a gear transmission; the free arm does not penetrate a support; and there is no stop post/stop slot on the planet gear. This is nevertheless the second-most-relevant citation for § 103 — it already teaches sun/planet-style synchronized rotation of multiple members and stop-plate retention of rotating arms.

• § 102 anticipation assessment: Unresolved on this record.

Verify against the full specification before relying on it either way.

Most relevant prior art — ranked

For a § 102/§ 103 challenge to claim 1 (the only independent claim), the citations rank in relevance as follows:

Bottom line on § 102 anticipation

No cited reference, on the record I can verify, fully anticipates claim 1 — and therefore none anticipates the dependent mechanism claims (2, 4, 5, 8, 9, 10) or the product claims (3, 6, 7, 11–14), because each incorporates claim 1's limitations by dependency. The systematic gaps across every mechanical citation are:

1. No cited toy reference discloses an electric motor disposed on a housing driving the sun gear through a gear transmission. The closest power sources are manual spin (US3449858A, US3510949A), a spring (US4648487A), user-twist + spring (US6022263A), or motorized toys without the sun/planet execution arrangement (US4629440A).
2. No cited reference discloses the full execution-unit geometry of claim 1 — insertion post sleeved by the planet gear, free arm penetrating the support, stop plate movably abutting the support, and a stop post received in a stop slot on the planet gear (US6022263A shows arm stop plates, but not this combination).
3. No cited reference discloses the dependent refinements (torsional free-arm position; same-position alignment notch/protrusion with matching sun-gear alignment marks; base/upper-cover support with accommodation interval; detachable torque-post/torque-slot coupling; worm + transmission-gear installation-rack train).

The practical implication: the cited art's real value is § 103 obviousness combinations — e.g., Balleis (US3449858A) or LCD (US6022263A) as the primary execution-mechanism reference, combined with a motorized-toy drive reference (US4629440A; US20230338867A1; US20240316472A1) to supply the "motor on a housing" element, and US12129976B2-type lighting for the toy claims. None of that was tested at the PTAB (see prior sections: zero IPR/PGR activity), so the question of what a skilled artisan would have found obvious remains open.

Caveats, stated plainly: (1) My anticipation conclusions for references 6–14 rest on bibliographic data where noted — I could not retrieve their full texts this session, and element-by-element § 102 mapping for those is incomplete. (2) The "no anticipation" finding concerns only the 14 examiner citations; a complete invalidity study should also sweep the uncited art in the same classifications (A63H29/22, A63H33/22, H02K7/116), e.g., Balleis' own later tops (US3691673A, US3898762A) and the "Similar Documents" listed beside this patent on Google Patents (US4983890A "Rotating drive device"; JP5330133B2; CN112720560B). (3) The authoritative confirmation of the citation list itself is the issued patent's front page via USPTO Patent Center — I verified against the Google Patents mirror, not the USPTO's native database.

§ 103 Obviousness Analysis — U.S. Patent No. 12,465,872 (US12465872B2)

1. Scope, legal framework, and art horizon

This analysis builds on the Prior-Art section of this record and assesses whether the claims of US12465872B2 would have been obvious under 35 U.S.C. § 103 to a person having ordinary skill in the art (PHOSITA), assuming the Graham framework (Graham v. John Deere, 383 U.S. 1 (1966)) and the flexible, common-sense inquiry of KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007).

Art horizon. The claims enjoy a priority date of 2024-11-15 (CN utility model CN202422799628.4U). Every one of the 14 examiner-cited references was patented/published and effectively filed before that date, so each qualifies as prior art under § 102(a)(1)/(a)(2) and is available in a § 103 combination. Notably, the two newest references — US20240316472A1 (published 2024-09-26) and US12129976B2 (granted 2024-10-29) — bracket the priority date by only weeks, confirming that the examiner considered this a crowded, fast-moving field.

Claims at issue. For § 103 purposes, the claims fall into four groups: (i) claim 1, the sole independent claim (motor + gear transmission + sun gear meshing plural planet gears, each one-to-one with an execution unit composed of insertion post / stop plate / free arm, plus a stop post received in a stop slot on the planet gear); (ii) mechanism dependents — claim 2 (torsional free-arm position), claims 4–5 (alignment keying and sun-gear alignment marks), claims 8–10 (base/upper-cover support; torque-post/torque-slot coupling; worm + transmission-gear train on an installation rack); and (iii) "electric toy" product claims 3, 6, 7, 11–14, each incorporating an earlier mechanism claim and adding light-emitting parts disposed in the housing/support.

Headline finding. The strongest § 103 case is a three-reference combination against claim 1 — Balleis (US3449858A) as the execution-mechanism primary, a motorized-toy reference (US4629440A; US20230338867A1; or US20240316472A1) supplying the motor/housing/gear-transmission, and LCD International (US6022263A) supplying the one-to-one planet-gear-to-arm coupling with stop-plate retention. Dependent claims add routine mechanical refinements — keying features, index marks, a two-piece gear housing, a detachable torque coupling, and a worm-reduction motor sub-frame — each obvious in light of the same art plus Christy (US3510949A) and Bandai (US4648487A). The toy claims add LEDs, which are obvious in view of Maichen (US12129976B2) and the general state of optical/lighted toys.

2. The person of ordinary skill in the art

A PHOSITA would be a designer or engineer with, say, a bachelor's degree in mechanical engineering (or equivalent experience) and 2–5 years designing geared, motorized toy mechanisms — gear trains, worm drives, cam/linkage outputs, and rotating decorative assemblies — familiar with the A63H29/22, A63H33/22 and H02K7/116 art areas (the classifications assigned to this patent). Such a person would routinely select among known drive trains (spur, worm, planetary), known torque-transfer interfaces (keyed shafts, D-shapes, post-in-slot), and known retention methods (flanges, stop plates, snap rings), and would treat visual-effect enhancements (twisted arms, LEDs) as ordinary design latitude.

3. Lead § 103 combination against claim 1: Balleis + LCD + a motorized-toy reference

3.1 Why Balleis (US3449858A) is the natural primary

Balleis discloses the structural skeleton of the claimed mechanism: a hand-spun top in which a central gear wheel on a disk meshes with several gear wheels 19–23 rotatably mounted in the same disk, each gear wheel's shaft carrying a colored toy figure (ball, multicolored umbrella, intersecting rings, toy vehicles). Rotation of the central gear rotates all of the surrounding figure-carrying gears synchronously on a shared support. That is the claim-1 concept of "one sun gear meshing plural planet gears, each planet gear one-to-one with a rotating execution unit on a support" — minus the motor. Balleis is the closest cited reference to the claimed execution architecture.

3.2 Why LCD (US6022263A) supplies the execution-unit geometry

LCD's doll fills the biggest structural gap in Balleis. LCD's specification expressly analogizes its gear train to "a planetary gear train, with two planetary gears being driven by a sun gear": a central drive gear 64 engages two driven gears 66A/66B mounted on arm shafts 29A/29B, so that rotation drives both arms in coordinated opposite motion; each arm shaft carries stop plates 79A/79B, and the arm connective portions are sandwiched between stop plate and shoulder to form a slip clutch. This supplies the claim-1 ideas of (a) planet gears sleeved on output shafts that are one-to-one with moving arms, and (b) stop-plate retention of rotating arm members — the two execution-unit limitations absent from Balleis.

3.3 Why a motorized-toy reference supplies the power train

Every cited sun/planet toy mechanism is manually powered (Balleis: hand-spun; Christy: hand crank; Bandai: spring; LCD: user twist + spring). The motor-and-gear-transmission half of claim 1 must come from the motorized-toy art:

• US4629440A (Mattel) — a motor inside a hollow toy body drives, through a gear train, rotating hubs on opposite sides; leg members are coupled to the rotating elements for coordinated, phased motion. This supplies "motor disposed on a housing" + "gear transmission component driven and connected to the motor" + plural coordinated moving members.
• US20240316472A1 (Bettyma, electric forklift toy) and US20230338867A1 (Hobbywing, electric motor and electric toy) — generic "electric motor mounted in a toy housing with a gear transmission" teachings, both published before the priority date.

3.4 Element-by-element map

3.5 Motivation to combine — the KSR analysis

The combination is motivated for several independent, mutually reinforcing reasons:

1. Motorization is the canonical improvement of a manual toy. Balleis and Christy both require continuous manual input; the toy market (as Mattel, MSC's electric yo-yo, Bettyma's forklift, and Hobbywing all show) had long since moved to motorized action toys. Replacing the hand-spun input with a small DC motor plus a reduction gear train connected to the central gear is a known element performing its known function — automation with predictable results. KSR holds exactly this substitution obvious.
2. The references are complementary, not conflicting. Balleis solves multi-output synchronized gearing; the motor references solve continuous powered drive; LCD solves coupling planet gears to articulated arms with retention. Nothing in Balleis or LCD teaches away from motorization — LCD's spring/twist drive is merely a power-source choice, and substituting a motor for a spring or manual spin in a geared toy is among the most routine steps in the toy art (Bandai itself shows the same sun/planet architecture with spring power; swapping in a motor is a design choice).
3. Design need / market pressure. Coordinated multi-part motion driven by a single motor is a recognized consumer expectation in action toys (Mattel's animated insect moves multiple limbs from one motor). Adapting Balleis' synchronized figure-spinner to motor power directly serves that need.
4. Obvious to try with a finite set of options. A PHOSITA wanting a motorized, synchronized multi-arm toy would select from a small known set of drive architectures; grafting a motorized gear transmission onto a known sun-gear/planet-gear output stage is an "obvious to try" scenario with a reasonable expectation of success — each element performs as designed, and synchronization is inherent in the gearing.
5. The execution-unit details are conventional engineering. The post-in-slot (keyed) drive between the sleeved planet gear and the output unit, the stop plate as an anti-withdrawal bearing surface, and an output arm passing through an opening in the support are all standard, predictable solutions a PHOSITA would apply without inventive thought — the kind of "routine design choice" KSR treats as obvious.

3.6 Reasonable expectation of success

High. The claimed benefits — synchronized execution units and elimination of multiple transmission shafts — are inherent properties of a sun-gear/planet-gear stage that Balleis and LCD already exploit. Combining a known output stage (Balleis/LCD), a known power source (any of the motorized toys), and known mechanical interfaces (keyed coupling, flange retention, through-hole routing) carries no technical risk.

3.7 Honest assessment of the weakest links

• No single reference discloses the full combination; a challenger needs three references for claim 1, which courts accept but which is a harder sell than a two-reference case.
• None of the cited motorized toys uses a sun gear driving plural planet gears, so the combination depends on articulating the motivation to graft motorization onto Balleis/LCD — a motivation that exists (continuous automatic synchronized motion) but must be argued affirmatively.
• The precise claim-1 geometry — planet gear "sleeved on" the insertion post, free arm "penetrated in" the support, stop plate "movably abuts" the support, stop post "between" insertion post and stop plate — is not literally present in any one reference. Claim construction of those phrases (e.g., whether LCD's stop plates "abut a support" as claimed) could decide the issue.
• The examiner considered all of these references and allowed the claims; the prosecution history (not available in this record) may contain applicant arguments distinguishing the art that would constrain a later obviousness case.

4. Alternative combinations for claim 1

If Balleis is displaced as the primary, two fallback combinations exist:

• LCD (US6022263A) as primary + motorization. LCD already has the sun/planet-analog architecture driving arms one-to-one with stop plates; the remaining gaps are (i) a motor and gear transmission (Mattel/Bettyma/Hobbywing) and (ii) a rotating sun gear on a support rather than a fixed gear with a rotating torso — a straightforward kinematic inversion. Weaker than the Balleis-led combination because LCD's sun gear is fixed and the inversion requires more explanation.
• Christy (US3510949A) + motor + LCD. Christy supplies a rotating base carrying planet gears on stub shafts meshing with a sun gear — structurally close to "planetary gears rotatably disposed on the support" — and adds the anti-collision phase design (deliberately non-multiple tooth counts) that maps to the alignment rationale of claims 4–5. Christy's outputs are magnetic pattern tracers rather than arms, so LCD would still be needed for the execution-unit structure.

Both fallbacks are viable but require more steps than the Balleis-led primary combination; Bandai (US4648487A) reinforces the sun/planet vocabulary but contributes nothing the others do not.

5. Dependent mechanism claims

5.1 Claim 2 — torsional position on the free arm

The "torsional position" is, per the specification, a segment of the free arm formed by twisting, creating a twisting visual effect during rotation. This is an ornamental modification with a predictable result — a twisted ribbon-like arm rotating about its axis appears to writhe/twist. Balleis already creates continuously rotating visual elements (umbrellas, rings, vehicles) on the driven gears, and LCD demonstrates that arm shape is freely variable to achieve different motions. Under KSR, purely aesthetic variations in the shape of an otherwise known output member are obvious design choices; nothing about the torsional position changes the mechanical function of the claim-1 mechanism. No additional reference is strictly needed, though the spinning/turning toy art (US7347119B2, "Turning machine"; Tomy's US20180214783A1 spinning-top launcher) reinforces that twisting/rotating toy elements were conventional.

5.2 Claim 4 — alignment notch on every stop slot + matching alignment protrusion on every stop post

Claim 4 is the claim-1 post-in-slot keying made orientation-specific: the notch sits at the same position on each stop slot and each stop post carries its protrusion at the same set position/orientation, so all execution units assemble at the same angle. This is a textbook anti-misassembly keying feature:

• The underlying post/slot torque coupling is already in the combination (see § 3.4).
• Christy (US3510949A) demonstrates that toy designers in this exact art deliberately controlled the angular/phase relationship of planet gears (non-multiple tooth counts so figures do not collide), showing the recognized need for phase management among planet outputs.
• Adding a visible orientation key (notch/protrusion) so assemblers cannot insert a unit at the wrong angle is the most routine fix for an assembly-error problem — a PHOSITA would apply it without invention.

Motivation: manufacturing yield and collision avoidance — the specification itself admits the feature exists "to avoid an error in an assembly angle as far as possible." Routine quality-engineering motivation.

5.3 Claim 5 — equally spaced alignment marks on the sun gear, one-to-one with the alignment protrusions

The sun-gear alignment marks are index marks that let an assembler clock each execution unit to its correct initial rotational position before the support is closed. Once claim 4's keying is adopted (and Christy shows why phase matters), placing visible index marks on the rotating gear periphery in one-to-one correspondence with the units is a conventional indexing solution found throughout mechanical assembly. Obvious for the same assembly-yield reason; it is a predictable implementation detail rather than a new function.

5.4 Claim 8 — base + upper cover with accommodation interval, through holes, avoidance holes, connecting hole

Claim 8 is a standard two-piece clamshell gear housing. Balleis already sandwiches his gearing between a stationary disk 12 and a rotating disk 17; converting the support into a base plate (with an installation hole seating the sun gear and through holes for the free arms to exit) plus an upper cover (with a connecting hole exposing the sun gear to the drive and avoidance holes in which the insertion posts rotate) is how any PHOSITA would package the known mechanism — Mattel's insect body and every toy gearbox in the art partition a hollow housing around a gear stage. Each hole type performs an ordinary function: seat a shaft (installation hole), pass an output (through holes), expose a drive interface (connecting hole), and journal rotating posts (avoidance holes). Obvious as a matter of conventional packaging.

5.5 Claim 9 — torque gear with torque transmission post inserted in a torque slot on the sun gear's central post

Claim 9 is a detachable keyed coupling between the final gear of the drive train and the sun gear's central post — the same post-in-slot torque-transfer principle as claim 4, used here as a quick-connect drive interface (the specification says it exists "for ease of installation and maintenance"). Bandai drives its sun gear through a gear train; Balleis' central gear receives external input; connecting a driven gear to a rotating post via a non-circular post-in-slot is the canonical detachable coupling in toy gear trains. Obvious.

5.6 Claim 10 — installation rack holding the motor; worm + transmission gears engaged in sequence; one gear engages the torque gear on assembly

Claim 10 packages the motor and a worm-reduction gear train on a modular sub-frame that aligns with the support when assembled. Each element is conventional:

• Worm-gear reduction for a toy motor is ubiquitous (compactness, high reduction ratio, self-locking hold) — Mattel's gear train and the motorized toy art generally teach motor-to-gear reduction, and the examiner's own citation of US10813807B2 (hollow rotary actuators with gearing) shows motor-gear integration was unremarkable even outside toys.
• Mounting the motor and reduction train on a separate installation rack that mates to the support is modular assembly practice — it simplifies manufacturing and aligns the final transmission gear to the torque gear automatically when the rack and support are joined. The claim even recites the alignment outcome ("when the installation rack is assembled in aligned and assembled with the support, the installation rack drives another of the transmission gears to be engaged with the torque gear"), confirming it is an assembly-alignment feature with a predictable result.

Motivation: torque multiplication, compact packaging, and modular manufacturing — standard engineering incentives, not inventive ones.

6. Electric-toy claims with light-emitting parts (claims 3, 6, 7, 11–14)

Each toy claim incorporates an earlier mechanism claim and adds "several light emitting parts… located in the housing and correspondingly disposed in the support." If the underlying mechanism claim is obvious, the LED addition is independently obvious:

• US12129976B2 (Maichen, "Tentacle animal bionic lamp") — filed 2024-05-13, granted 2024-10-29 (weeks before the priority date) — already combines motor-driven multiple moving members with light emission, exactly the visual-effect combination the toy claims seek. This is the strongest single teaching for the LED layer.
• US9474981B1 (William Mark, plush toy with mood change) and the A63H33/22 (optical/colour toys) classification confirm that light/color effects were a standard toy feature.
• Lighting rotating toy parts so they glow, twinkle, or attract attention in the dark is a known use of a known element (LEDs in toys) for a known purpose (visual appeal) — the specification itself states the LEDs "increase visual attraction of the toy, so that the toy can attract attention of users in a dark environment," which is precisely the predictable benefit that makes the addition obvious. Synchronizing the lights with mechanism motion is a routine control choice.

No claim in this group adds a patentable LED function (no novel optics, no light-piping structure, no control circuitry is claimed); the LED limitation is conventional.

7. Graham-factor assessment and secondary considerations

• Scope and content of the prior art: the 14 cited references collectively teach every functional element of the claims — sun/planet synchronized output stages (Balleis, Christy, Bandai, LCD), motorized toy drives (Mattel, Bettyma, Hobbywing, MSC), arm/stop-plate execution units (LCD), phase control among planet outputs (Christy), and motorized motion plus lighting (Maichen).
• Differences between the prior art and the claims: the differences are (i) motorization of manually powered sun/planet toys, (ii) the specific execution-unit chain (insertion post/stop plate/free arm with post-in-slot keying), and (iii) packaging/alignment details. None of these differences changes the function of any known element; each is a substitution or routine design choice.
• Level of ordinary skill: see § 2; a PHOSITA in motorized toy gearing would find the combination trivially within reach.
• Secondary considerations: none appear on the record. There is no evidence of long-felt need, commercial success, copying, licensing, unexpected results, or industry skepticism — unsurprising for an individual-owned patent issued 2025-11-11 with no litigation and no PTAB challenge (see prior sections). The specification's touted benefits — synchronization and elimination of redundant shafts — are inherent properties of a sun/planet stage already demonstrated in Balleis and LCD, so they cannot support a non-obviousness argument as unexpected results. The absence of secondary considerations leaves the obviousness case unrebutted on this record.

8. Bottom line

Overall: the claims' strongest defense is not the absence of a motivation to combine, but the accumulation of structural specifics in claim 1 (the insertion-post/stop-plate/free-arm chain, the "penetrated in the support" relationship, and the stop-post/stop-slot keying) that no single reference discloses and that require a multi-reference combination plus reliance on conventional-engineering characterizations. Every dependent claim adds only routine mechanical or ornamental detail. A well-constructed § 103 challenge targeting claim 1 — with Balleis as the primary, a motorized toy supplying the power train, and LCD supplying the arm/stop-plate output stage — is the strongest avenue, with the LED "toy" claims falling as a matter of course if their underlying mechanism claims fall.

9. Caveats, stated plainly

1. Verification limits. References 6–14 were not fully retrieved during prior analysis; this § 103 analysis deliberately builds combinations only on the verified content of Balleis, Christy, Mattel, Bandai, LCD, and the bibliographic-record content of Maichen, William Mark, Hobbywing, and Bettyma. Element mappings for unverified references should be confirmed against full texts before reliance.
2. Prosecution history not reviewed. The examiner allowed the claims over all 14 references. The file wrapper (via USPTO Patent Center) may contain applicant arguments distinguishing Balleis/LCD or narrowing claim scope; those arguments could support prosecution-history estoppel or a "swearing" of particular claim meaning, and should be checked before any invalidity position is finalized.
3. No PTAB or court testing. No IPR/PGR has been filed and no court has construed any claim (see prior sections), so claim terms such as "sleeved on," "penetrated in the support," and "movably abuts" are unconstrued. Obviousness conclusions here assume their plain meaning.
4. Uncited art. This analysis is limited to the 14 examiner citations. A complete § 103 study should also sweep the uncited art in A63H29/22, A63H33/22, and H02K7/116 — including Balleis' later spinning tops and the "Similar Documents" Google Patents lists beside this patent (e.g., US4983890A "Rotating drive device," JP5330133B2, CN112720560B) — which may supply even closer single-reference disclosures of motorized sun/planet toy drives.
5. Legal conclusion. Whether any combination renders the claims obvious is ultimately a legal conclusion for a court or the Board, reached after claim construction and a full factual record; this analysis identifies the strongest available combinations and the motivations a challenger would need to establish, not a guaranteed outcome.
