Patent Overview — US 146,265
Title: Improvement in Combined Bedsteads and Cribs
Patentee: Charles Morgan, of Bridgeport, Fairfield County, Connecticut
Patent Number: US 146,265
Application Filed: July 17, 1873
Granted/Published: January 6, 1874
Anticipated Expiration: January 6, 1891; status listed as "Expired – Lifetime"
Classification: A47D9/016 — Cradles/bassinets attachable to other articles, e.g., an adult's bed
Purpose: The invention addresses the class of bedsteads in which a child's crib or smaller bedstead is combined with an ordinary bedstead. Morgan sought a "cheap and durable" combined bedstead and crib that is lighter and more ornamental than existing arrangements.
Plain-language scope: One side-board (B) of the main bedstead, while still supporting the main slats, has an outer portion (C) that can be drawn out to form the crib's side, plus a portion (D) hinged to the side-board so it folds out to form the crib's foot-board and support. Projection c on part C seats in a recess in part D when stored, and in recess c¹ when deployed. A second series of sliding slats (b b) sits beneath the main slats, supported at one end by portion C and, at the other, by a connecting strip (H) sliding in grooves in the stationary part of the main side-board. The crib head-board (E) slides in a groove or channel in the main head-rail. Alternatively or additionally, an ornamental head-board (F) pivots on main post A, held in place by a spring-catch and turned out of sight when unused.
Claims:
- The combination, with the side-board B of a bedstead having a second series of sliding slats (b b), of the divided outer portion C D.
- In such a bedstead, the combination, with side-board B and outer portion C D, of the pivoted head-board F.

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.
