Patent Overview: US 370,363 — Cash Indicator and Register
Title: Cash Indicator and Register
Patentee: Jerome J. Webster, of Newport, Vermont
Assignee: Boston Cash Indicator and Recorder Company, of Bangor, Maine
Application filed: October 7, 1886
Patent granted/published: September 20, 1887
Publication number: US370363A
Classification: G07G1/00 (Cash registers)
Legal status (as listed): Expired – Lifetime (anticipated expiration 1904-09-20)
Purpose (from the specification):
The invention relates to "cash indicators and registers," consisting of "the devices and combinations hereinafter described and claimed." It provides a case that conceals the operating mechanism and signals except when raised, with a glass window on each side so signals may be read by a cashier behind the case and by customers in front.
Plain-language scope, as described in the excerpt:
- A spring-pressed till is held closed by a locking-spring, released by rocking a fulcrum-rod when any signal-key is depressed.
- Signal-keys on the fulcrum-rod raise numbered signals (zero, cents, dimes, dollars) and are guided and limited by slotted stop/guide plates.
- A spring-loaded locking-rod with pins locks a raised signal until another key is depressed; a bell is struck by a spring-hammer on the locking-rod's return, calling attention each time the till opens.
- Registering devices for cents, dimes, and dollars use ratchets, gears, single-toothed pinions, impelling/locking/retaining pawls, registering-levers, and index-fingers, graduated and numbered for reckoning receipts.

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.
