Purpose
Grids displayed on computing devices (e.g., calendars, television schedules, timelines, spreadsheets) organize content into cells. Cells may be uniform or non-uniform in size. Depending on a cell's size, a content item shown in it may be truncated. The patent addresses revealing that truncated content when the grid is scrolled.

Plain-language scope (from the supplied excerpt)
One disclosed embodiment is a computing device with a display, processor, and memory storing executable instructions to: display a cell of a content grid at a first, smaller size; display within that cell a content item truncated based on the smaller size; receive a request to scroll the grid; scroll the grid on the display device; increase the cell to a second, larger size; and animate the revealing of the truncated portion of the content item. The excerpt also notes the disclosure includes a flow diagram (FIG. 1) of "an embodiment of a method of presenting a scrollable gri[d]…" (text truncated in the excerpt).

Classifications listed: G06F3/0481, G06F3/0485, G06F3/0488, G09G5/34, G09G5/373, G09G2340/145, among others.

What the excerpt does not establish
The supplied text is expressly an excerpt with omitted content. It therefore does not establish: the full claim set or claim language; the complete written description, figures, or exact method steps; the precise intended scope of "revealing" or "animating"; any legal conclusions about validity, enforceability, or claim coverage; and any litigation, assignment, or ownership details beyond the bibliographic entries listed. The excerpt contains no prior-art discussion or references, so no prior-art analysis is possible from it. Dates are presented as the source's assumptions, not verified conclusions.

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.
