Assignment history

Inventors

The sole named inventor for US Patent 10,783,192 is Dmitri Soubbotin. At the time of filing (December 4, 2015), the patent identifies the original assignee as "Individual," which suggests Dmitri Soubbotin was self-assignee or the patent was initially assigned to him directly. There is no employer explicitly listed for the inventor at the time of filing within the provided patent document.

Original assignee

The entity named on the issued patent US10783192B1 is "Individual" (as per Google Patents and the patent document itself). Given the assignee is an individual, it is not possible to definitively determine if a product embodying the claims was shipped by this "Individual" in a traditional commercial sense, nor to define their primary line of business or current operating status as one would for a corporate entity. The patent describes a "System, method, and user interface for a search engine based on multi-document summarization," indicating the invention is a functional software system.

Assignment timeline

As a large language model, I do not have direct access to live, real-time external databases such as the USPTO Patent Assignment Search portal (https://assignmentcenter.uspto.gov/). Therefore, I cannot reconstruct the full assignment record for US Patent 10,783,192 as of today's date, 2026-05-30.

Based on the information available in the patent document and Google Patents, the original assignee on record is an "Individual." If no assignments are found in the USPTO database, it typically indicates that the patent remains owned by the original assignee.

NPE / troll-pattern signals

1. Shell-entity transfer — Unclear. The original assignee is an "Individual," not a named corporate entity. Without assignment records, it's impossible to determine if it was later transferred to a shell entity.
2. Known asserter in the chain — Not present. There are no recorded assignments visible in the provided patent information to any known NPEs.
3. Repeat correspondent across the chain — Unclear. Without access to assignment records, the correspondent information for any potential transfers cannot be determined.
4. Cascading transfers — Not present. There are no recorded assignments in the provided patent information to indicate any transfers, let alone cascading ones.
5. Pre-litigation transfer — Not present. No litigation has been identified as of May 1, 2026, and no transfer records are available.
6. Bankruptcy fire-sale — Not present. There is no indication in the provided patent information or litigation search results that the original assignee (Individual) has filed for bankruptcy or that the patent was sold in such proceedings.
7. Privateering — Unclear. There are no recorded assignments, nor any SEC filings or other public information indicating a privateering arrangement.
8. Defensive aggregator (anti-NPE) — Not present. There are no recorded assignments indicating transfer to a defensive aggregator.

Verdict

Insufficient data

Without access to the USPTO Patent Assignment Search database, it is not possible to determine the complete ownership chain of US Patent 10,783,192 beyond the original assignee being an "Individual." Consequently, there is insufficient data to confidently identify any NPE/troll patterns.
