Patent Overview — US 10341937 B2
Title: Dead zone for wireless communication device
Patent number / application: US 10341937 B2; Application US 15/910,190; pre-grant publication US 20180192353 A1.
Inventor: Paul R. Juhasz. Original assignee: Individual. Current assignee listed as Deadzone US LLC (assignment recorded 2020-07-16, assignor Paul R. Juhasz).
Dates: Priority date 2008-10-02; filing date 2018-03-02; publication date 2019-07-02; granted 2019-07-02; anticipated expiration 2029-09-30. Legal status: Active (as stated by the source).
Classification: H04W 48/02 (access restriction under specific conditions); H04W 4/029 (location-based management or tracking services).
Purpose: The invention addresses use of wireless communication devices "in places or at times when they should not be used," citing cell phone use while driving, potential interference with medical equipment, and earlier systems that only silenced phones (e.g., U.S. Pat. No. 6,979,724; Japanese applications H10-42371 and J11-004190). The source states neither prior-art approach "disables the use" of such devices where they should not be used.
Plain-language scope (per the supplied text): A communication system includes a wireless device with a GPS detector providing positioning data, and a network that receives that data and maintains a "no communication zone register" — a database of predetermined zones ("dead zones") where certain communication by, to, or by and to the device is disabled. The network tracks device location and disables that communication. Alternatively, the wireless device itself may hold the no-communication zone register, track its own location, and disable itself. Disabling may be via a network service restriction, an over-the-air-programmed flag in the device, or a message indicating service is interrupted. The zone may be a GPS location or device speed derived from GPS data. The device and/or network may recognize hands-free operation and allow messages in that mode.
Not established by this excerpt: The full text of the claims, the complete priority chain, and the remainder of the description were not supplied; the excerpt omits material after "the cert…". Verification of legal status, ownership, and prior-art effect is outside this overview.

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.
