Purpose and plain-language scope (per the supplied text): The patent concerns a multi-function, "smart," tokenizing electronic payment device. Based on the classification entries provided, the device falls in payment architectures using cards — specifically active cards containing their own processing means (e.g., an IC or chip) — and covers record carriers with magnetically detectable marking that is emulated, contactless payment cards, chip cards with a sensor or sensor interface, and non-contact smart card antenna construction. Classifications also indicate payment protocols addressing security, including message hashing and use of an alias or single-use code, plus transaction verification such as PIN verification, e-cash/private payment circuits, and peer-to-peer payment schemes. The listed "prior art keywords" are: payment, parameter, transaction, information, per.

What the excerpt does not establish:

  • It does not include the claims, abstract, or detailed description, so the actual claimed scope, claim language, and dependencies cannot be confirmed.
  • It does not establish the accuracy of the priority date, expiration date, legal status, or assignee listings (each is expressly flagged as an assumption in the source).
  • It does not establish validity, enforceability, patentable subject matter, or the content/effect of any prior art.
  • No litigation, ownership-transfer, or licensing details are addressed here, consistent with the scope of this overview.
  • The excerpt also does not confirm whether the priority date reflects a single earlier application or a chain of related applications (a later US19/429,187 priority entry appears, but its relationship is not explained).

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.
