Patent 9270744

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 — Not present. The only recorded assignment is from the inventors to the operating company, Damaka Inc. There is no evidence of a transfer to a licensing-only LLC.
  2. Known asserter in the chain — Not present. Damaka Inc. is not identified as a known NPE.
  3. Repeat correspondent across the chain — Not present. There is only one recorded assignment, making it impossible to identify a repeat correspondent within the chain. The correspondent is BARRY C. HURWITZ, ESQ.
  4. Cascading transfers — Not present. There is only one recorded assignment.
  5. Pre-litigation transfer — Unclear. There is a PTAB case IPR2026-00207 filed against this patent. However, without knowing the exact filing date of the IPR and any associated litigation, it's unclear if the sole assignment (2015-04-21) falls within 6 months prior to the first infringement suit.
  6. Bankruptcy fire-sale — Not present. There is no indication that Damaka Inc. has filed for bankruptcy.
  7. Privateering — Not present. There is no evidence of Damaka Inc. transferring this patent to an NPE to assert on its behalf.
  8. Defensive aggregator (anti-NPE) — Not present. The current assignee is Damaka Inc., which is an operating company, not a defensive aggregator like RPX, AST, LOT Network, or Unified Patents.

Verdict

Insufficient data. The USPTO assignment records only show the initial assignment from the inventors to the original assignee, Damaka Inc. While there is pending PTAB litigation, without further information on the nature and parties involved in any associated infringement suits, it is not possible to confidently determine an NPE pattern.
