Patent 7603382

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.

NPE / troll-pattern signals

  1. Shell-entity transfer — present. Roscoe Technologies LLC, which received the patent from the law firm Volpe & Koenig PC (Reel 017596/0781), exhibits characteristics of a shell entity, acting as an intermediary before the patent was transferred to Intellectual Ventures I LLC. Intellectual Ventures I LLC is a well-known licensing-only entity.
  2. Known asserter in the chain — present. Intellectual Ventures I LLC, a prominent NPE, is the current assignee (Reel 030494/0374).
  3. Repeat correspondent across the chain — present. Michael F. Ryan of Volpe and Koenig, P.C., is listed as the correspondent for the first two assignments (Reel 016686/0948, Reel 017596/0781). This suggests a consistent legal representative for the initial transfers.
  4. Cascading transfers — not present. The assignments occur over several years rather than in quick succession.
  5. Pre-litigation transfer — unclear. While the patent has been involved in litigation, the precise timing of the assignments relative to the first infringement suit naming this specific patent is not definitively established in the provided data to make a strong claim of pre-litigation transfer.
  6. Bankruptcy fire-sale — not present. No indication of bankruptcy proceedings for the original assignee or Roscoe Technologies LLC.
  7. Privateering — unclear. No direct evidence in the assignment records or legal events explicitly points to privateering.
  8. Defensive aggregator (anti-NPE) — not present. The chain terminates with Intellectual Ventures I LLC, which is an asserting entity, not a defensive aggregator.

Verdict

NPE — high confidence. The presence of Intellectual Ventures I LLC, a well-known patent assertion entity, as the current assignee (Reel 030494/0374), combined with the initial transfer from an individual inventor to a law firm and then to an LLC (Roscoe Technologies LLC) which then merged into Intellectual Ventures, strongly indicates an NPE pattern. The consistent correspondent for the initial transfers further supports this.
