US 12649534 B2 — Patent Overview
Title: Electric riding device
Patent number: US 12649534 B2 (application US19/341,002; pre-grant publication US20260028081A1)
Assignee: Shenzhen Chitado Technology Co Ltd (listed as both original and current assignee)
Inventors: Dianxuan Zhang, Yang Zhang, Yiqiang Wang, Dengbing Zhou, Fuqi Zhou
Key dates: Priority 2024-07-03; filed 2025-09-26; granted/published 2026-06-09; anticipated expiration 2045-07-03. Legal status listed as "Active" (an assumption per the source, not a legal conclusion).
Purpose and plain-language scope: The patent concerns a battery-powered ride-on vehicle — the classification data points to a two- or three-wheeled scooter-type device with a foldable frame, a propulsion battery, a motor at the driven wheel, handlebars, and foot rests. According to the "prior art keywords" the claimed subject matter centers on a frame body combined with a storage basket and a support plate — i.e., an electric riding device in which a carrying basket and a supporting plate are integrated with the vehicle frame, with the frame also described as able to support luggage/cargo. The class listing further suggests the battery is arranged for propulsion on a motorcycle-like vehicle, with luggage-carrier and container features (including quick-release style mounting arrangements) built into the frame. In plain terms: a compact electric scooter or similar rider vehicle whose frame is configured to carry and secure a basket and support plate.

What the excerpt does not establish:
- The actual claim language — no claims are reproduced, so the precise scope of the monopoly cannot be confirmed. The "scope" above is inferred only from titles, keywords, and classifications.
- The written description, drawings' content, or any embodiment details beyond classification labels.
- Any relationship to the listed Illinois Northern District Court case or the Darts-ip litigation flag (deliberately not researched here).
- The validity, enforceability, or legal effect of the "Active" status, or whether the priority date is correct (the source itself calls it an assumption).
- Whether the listed assignees are accurate (again, the source disclaims verification).
Note: the supplied text is heavily excerpted; any figures or full claim set must be taken from the linked source.

PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
