Patent Overview — US 10638810 B1
Title: Rapid-entry footwear having a compressible lattice structure
Patent number / application: US 10638810 B1; application US 16/720,382
Inventors: Craig Cheney; Steven Hermann
Assignee: Fast IP LLC (original assignee per the source; listed as current assignee on the page)
Key dates: Priority date 2019-01-07; filed 2019-12-19; granted/published 2020-05-05; anticipated expiration 2039-12-19. Status: Active.
Classification context (selected): A43B11/00 (footwear arrangements facilitating putting-on/removing); A43B23/02 (uppers); A43C11/00 (other fastenings).
Purpose (plain language): The patent describes a "rapid-entry shoe" designed for easy donning and doffing. The shoe's heel portion has a compressible lattice structure that can be squeezed down under the foot/heel and then recoils back up once the downward force is removed. This lets the shoe open with an expanded opening to receive a foot, then bias back toward a closed position with a smaller opening to retain the foot.
Scope (plain language): The compressible lattice structure comprises one or a plurality of interconnected, overlapping, intersecting and/or woven ribs defining one or more apertures (e.g., diamond-like or other shapes). The apertures are described as open, pass-through slots or holes extending completely through the lattice structure, and not mere folds, pleats, surface grooves, or surface channels. The lattice structure is described as distinct from ordinary fabric/textile because it is reversibly compressible and recoils; it may be a unitary structure formed from a single mold and may comprise a polymer, metallic, or composite material. The disclosure also describes lattice stabilizers, filled voids, upper and lower flanges, a yoke, and a split lattice structure.

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.
