Patent Overview: US 9,894,019 B2
Title: Two-way real time communication system that allows asymmetric participation in conversations across multiple electronic platforms
Assignee: Disintermediation Services, Inc. (original assignee and current assignee as listed)

- Priority date: 2011-10-17
- Filing date: 2015-07-30 (application US 14/814,337)
- Publication of US 2015/0341288 A1: 2015-11-26

- Anticipated expiration listed: 2032-10-16; status listed "Active"
Purpose: The patent addresses the problem that real-time communication (RTC) modes—instant messaging, SMS/text, and email—are not interconnected, so participants traditionally must share a common protocol and know each other's addressing information. The disclosed system enables "asymmetric participation," letting parties converse in real time across different electronic platforms.
Plain-language scope (from the excerpted description and summary):
- A responder provides conversation selection criteria and a mode-of-communication (email address, telephone number, or instant-message identifier).
- An initiator submits a conversation request identifying a topic but not any responder.
- The system creates a conversation identifier, determines possible responders from the topic and selection criteria, and picks each responder's communication mode.
- The topic is sent to responders without identifying the initiator, possibly using a second mode different from the initiator's first mode.
- A responder's reply, received via that second mode, is mapped to the conversation via the conversation identifier and delivered to the initiator in the first mode.
Corresponding systems, apparatuses, and computer-readable media are also claimed. Classifications include H04L51/00, H04L51/04, H04L51/56, H04L65/1104 (SIP), and G06F21/31.
What the excerpt does not establish: the full claim language or claim count; the complete specification; whether any references were cited or applied during prosecution; and the accuracy of legal-status, priority, expiration, or assignee listings (explicitly disclaimed in the source). Family members and litigation entries appear in the source but are outside this overview's scope.

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.
