Inventors: William E. Gossman; Peter J. Hartmaier
Current assignee (as listed): Unwired Planet LLC
Original assignee: Openwave Technologies Inc
Priority date: 1996-09-27 (claimed from US08/720,089, which issued as US5978672A)

Purpose and plain-language scope (per the supplied text):
The patent concerns a system and method for supplying data to a wireless device when activity of that device on a wireless network is detected. The source's own key terms cluster around "detection of activity," "response to activity," "wireless network," "external" devices/networks, "cellular," "communication," "monitoring process," and "computer program." Its classifications include H04W8/02 and H04W8/08–8/10 (mobility data processing and transfer between location registers and external networks) and H04Q3/00–3/0045 (intelligent networking, including hybrid public/private and multi-vendor systems), with H04M3/42 subclasses for special subscriber services.
Read together, the claimed subject matter appears directed to a network-side arrangement that watches for wireless-device activity and, upon detecting it, delivers data to the device. The excerpt suggests mobility/location-register signaling as the mechanism and an intelligent-network or special-services context, but it does not state the claims verbatim.
What this excerpt does not establish:
- The actual text of the claims or the precise scope of any claim.
- The abstract and full description (both listed, but not reproduced here).
- Which specific references constitute prior art, or any validity analysis.
- The nature, parties, or outcomes of the litigation entries listed.
- Whether the listed assignees are accurate (Google expressly disclaims legal analysis of ownership).
- The content of related family member US7359720B2 or US5978672A.

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.
