Inventors: Philip D. Lapsley; Jonathan Alexander Lee; David Ferrin Pare, Jr.; Ned Hoffman
Assignee of record (per source): Originally YOU Technology Inc. Current assignee listed as Open Invention Network LLC. (The source cautions that listed assignees may be inaccurate and that no legal analysis was performed.)
Priority: 1994-11-28 (claimed from US08/345,523), with further priority claims to US08/442,895 (1995-05-17), US08/705,399 (1996-08-29), and US09/239,570 (1999-01-29).

Purpose / Plain-language scope (inferred from the title, abstract-level metadata, and classifications in the supplied text): The patent concerns electronic financial transactions conducted without a token (e.g., without a card or similar physical credential), where a party's identity is verified biometrically through a third-party "identicator." The prior-art keywords supplied — payee, payor, biometric, transaction, identification — indicate the subject matter centers on identifying payors/payees biometrically to authorize payments.
Classifications cited: G06Q20/00 family (payment architectures/schemes, third-party and remote-charge payments), G06Q20/04 (payment circuits), G06Q20/10 (electronic funds transfer/home banking), G06Q20/12 (electronic shopping), G06F21/32 (biometric user authentication), H04L63/04, and others.

What this excerpt does not establish: The supplied text contains only bibliographic data, classifications, and assignment/legal-status metadata — no claims, detailed description, or drawings. It therefore does not establish the actual claimed scope, specific embodiments, or how the "third party identicator" operates. The title and keywords are not a substitute for claim language. Per instructions, no litigation, ownership-transfer validity, or prior-art analysis is offered here.

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.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
