Patent Overview — US 7,492,386 B2
Title: Display management during a multi-party conversation
Patent number: US 7,492,386 B2 (application US 10/982,655)
Inventors: Paul Henry Nichols; Myra Louise Rice; Carey Lloyd Moulton
Original assignee: Sony Ericsson Mobile Communications AB. The source's current-assignee field lists III Holdings 1 LLC, but the page cautions that listed assignees may be inaccurate and that no legal analysis or warranty is made.
Key dates (as stated, some characterized as assumptions in the source): Filed 2004-11-05; priority date 2004-11-05; published as US 2006/0098085 A1 on 2006-05-11; granted 2009-02-17; adjusted expiration 2026-11-06. Legal status shown as active.
Purpose: Addressing display management for wireless communication devices during a teleconference. The source notes that users are often limited to a default display established by the network or device during call setup, that device displays are relatively small, and that teleconference images typically use the entire display, restricting access to other device features.
Plain-language scope: The described invention manages a display during a teleconference among a primary participant and one or more secondary participants. A primary image (the primary participant) appears in a first display section, while a subset of a series of secondary images (the secondary participants) appears in a second section; scrolling shows a different subset. In further described embodiments, images are shown on separate layers with opacity adjusted to allow simultaneous access, and the primary image may be interchanged with a selected secondary image. A corresponding wireless communication device includes a display and a controller performing the scrolling or interchange. Selected drawings: FIGs. 1–7C.

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.
