Purpose and plain-language scope
The patent addresses broadcasting a data file—particularly a multimedia file such as MPEG-1 video or MP3 audio—during an ongoing video conference. Rather than sending the file in full over a separate data channel (which is slow and leaves the receiver with a copy), the invention broadcasts the file in real time using the audio and video channels already open for the conference, without breaking the communication. The receiver never obtains the file itself.
When the conference is established, the terminals negotiate parameters (bandwidth, frame rate, frame size, coding standards), and the broadcast respects the negotiated bandwidth and the constraints of the receiving terminal. The file's video and audio are decoded and mixed in real time with the sender's captured camera/microphone signals, then coded per the negotiated codecs.
The invention also covers a man-machine interface that displays "local" and "distant" windows plus a further window showing available files as icons; a logic module couples selecting a file and moving it into the "distant" window with launching the real-time broadcast program. The sender need only drag and drop a file icon onto a distant window.

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.
