Purpose
The invention relates to wireless mesh networking, described as particularly useful in residential multimedia environments because it permits high-speed, direct communication between wireless nodes while also providing data routing. A stated aim is enabling channel-interference minimisation, power optimisation and traffic control with minimal modification to existing wireless nodes, and easy integration with legacy architectures.
Plain-language scope
The network comprises wireless nodes, each coupled to other nodes by a dedicated link defined as an agreement between two nodes to rendezvous at a predetermined time on a predetermined channel to exchange data. A link is established by the endpoints negotiating a rendezvous—selecting a rendezvous channel and rendezvous instance characteristics (times, duration, power)—and storing that information at each endpoint. Rendezvous start times fall within a cyclic mesh network transmit window; at each rendezvous the endpoints exchange data for the rendezvous period. Node logic enables intelligent packet routing at defined link rendezvous instances. Links may be unidirectional or bidirectional, and link state advertisements are flooded to build a topological database. The specification also describes a power-save mechanism for juggling multiple simultaneous ad-hoc connections so a node wakes only when communication is likely, and handshaking protocols to control data flow and minimise loss.
Not established by the supplied excerpt
The excerpt omits the claims, so the precise claim scope is not shown. It also does not provide detailed embodiments for Figures 7–11 (handshake/forwarding flows and legacy integration), the complete "FIG. 2" description, or the full negotiation steps of Figure 5. It does not address (and per instructions was not researched) litigation, ownership-transfer history, validity, or prior art.

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.
