Patent Overview: US6647260
Title: Method and system facilitating web based provisioning of two-way mobile communications devices
Patent number: US6647260 (B2); application US09/289,559; also published as US20020068554A1.
Assignee/owner (as listed in the supplied text): Original assignee Openwave Systems Inc; "Current Assignee" listed as PHONECOM A DELAWARE Corp and Unwired Planet LLC. (Per your instructions, ownership transfers are noted only as they appear in the source and are not researched or analyzed.)
Inventors: Steve Dusse; Peter F. King; Bruce V. Schwartz; Bruce K. Martin, Jr.
Dates: Priority/filing date 1999-04-09; granted 2003-11-11; anticipated expiration 2019-04-09; status listed as "Expired - Lifetime."
Purpose: The invention addresses provisioning—the parameters and settings that must be loaded into a two-way mobile communications device (e.g., cellular phones, two-way pagers, PDAs, handheld computing devices) to enable communication services, applications, and to distinguish the device within the network. The stated motivation includes reducing fraud (subscription and cloning) and network-element involvement. The definitions section notes 1997 industry fraud losses of about $600M (cloning) and $400M (subscription).
Plain-language scope (from the excerpt):
- Device-initiated provisioning: the device establishes a secure session with a provisioning server; a user is presented with input/choice screens via the device's display and user interface to enter information and select features/services. Information is forwarded to the provisioning server, which generates provisioning content and notifications. An intermediate server may be used.
- Server-initiated provisioning: a remote server establishes a secure session with the provisioning server and supplies user information and desired features/services. User information may be collected via a telephone with an Interactive Voice Response Unit (IVRU) or through a representative.
- Provisioning packages may include software modules, parameters, and required security information.
- Stated advantages include initial provisioning without visiting a retail establishment, user-initiated changes after provisioning, and remote carrier changes.
Classification (source-listed): H04W 8/24, H04W 4/50, H04W 12/35, H04L 67/34, H04L 67/04, among others.
What the excerpt does not establish: claim language and claim count; detailed embodiments, figures, or flow-charts; specific security protocols; named prior-art references; litigation history, outcomes, or validity; and any legal conclusions about ownership or status.

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.
