Patent 7606156

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.

Inventors

Original assignee

The original assignee on the issued patent US7606156B2 was Individual. However, Google Patents indicates "Competitive Access Systems Inc" as the Current Assignee, and an assignment event on 2021-05-13 states "Assigned to COMPETITIVE ACCESS SYSTEMS, INC.". It is unclear if Eric M DeLangis operated under "Individual" at the time of filing or if this indicates a subsequent assignment to himself or an unrecorded initial assignment. Competitive Access Systems Inc. appears to be an operating company based on its website, offering communications solutions. Their current status is operating.

NPE / troll-pattern signals

  1. Shell-entity transfer — not present. The transfer is from the individual inventor to an operating company, Competitive Access Systems, Inc., which appears to offer communications solutions.
  2. Known asserter in the chain — not present. Competitive Access Systems, Inc. is not a known NPE.

  5. Pre-litigation transfer — unclear. While there are active litigation cases, the earliest listed is 2024 (e.g., "US case filed in North Carolina Eastern District Court" 2024-05-15), and the assignment was recorded in 2021.
  6. Bankruptcy fire-sale — not present. No indication of bankruptcy for the assignor or assignee in the provided information.

Verdict

Operating-company assertion The sole recorded assignment is from the inventor, Eric M. DeLangis, to Competitive Access Systems, Inc. (reel 056461/0816), which appears to be an operating company. While the patent has active litigation, these appear to be assertions by the operating company.
