Patent Overview — US 3648020A
Title: Automatic deposit-receiving and cash-dispensing system
Assignee: Original assignee Omron Tateisi Electronics Co.; current assignee listed as Omron Corp. Inventors: Kazuma Tateisi, Yukio Mizuta, Shizuya Ano.
Dates: Priority date 1969-04-26; application filed 1970-04-15 (application number US28635A); granted and published 1972-03-07; anticipated expiration 1989-03-07; status "Expired - Lifetime."
Purpose: The patent addresses banking services that otherwise require a teller. Its stated object is a system enabling a customer to make both deposits and withdrawals using one and the same card, working selectively as an online or offline system, with the account balance confirmed and rewritten at real time. A further object is preparing a slip bearing the card's embossed information and transaction data, in duplicate, so one copy serves as the customer's memo showing balance and remaining card uses.
Plain-language scope: The system contemplates a bank-issued customer identification card, an automatic deposit-receiving and cash-dispensing machine, a data-transmitting system, and an electronic computer storing all participating customers' account balances. The card carries common data (visible/embossed bank name, availability term, usable banks, account number; signature area) and separately recorded deposit-only and withdrawal-only data (secret number, remaining withdrawal uses, deposit count, balance), invisibly recorded, e.g., magnetically. The machine checks card genuineness and read-data errors, reads coded information, and transmits account number, amounts, and other data to the computer, which rewrites the balance and returns information so the machine accepts a deposit or dispenses cash, printing a slip. A manually entered secret number is compared with the number read from the card to verify the proper owner, helping prevent fraudulent use. FIG. 1 shows the machine front panel with indicating windows and an inlet slot; FIG. 4 is a block diagram of the whole system.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
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.
