NPE / troll-pattern signals

  1. Shell-entity transfer — unclear. The transfers between Pyromart Inc. and Titan International Technologies Ltd. are noted, but without specific information on their business activities or corporate structures (e.g., registered agent addresses, product lines), it's unclear if these entities are shell companies.
  2. Known asserter in the chain — not present. Neither Pyromart Inc. nor Titan International Technologies Ltd. are identified as known NPEs in the provided information.
  3. Repeat correspondent across the chain — unclear. The correspondent information (attorney name, firm, address) is not provided in the supplied text for any of the assignments, so it is not possible to determine if there is a repeat correspondent.
  4. Cascading transfers — present. There are three transfers in a relatively short period (2021, 2023, 2024), which could suggest cascading transfers. The transfers happened between Pyromart Inc. and Titan International Technologies, Ltd..
  5. Pre-litigation transfer — present. The patent was assigned to Titan International Technologies, Ltd. on January 26, 2024. Litigation in the Nevada District Court (case 2:24-cv-00861) was filed in 2024, though the exact filing date is not specified beyond the year. This proximity suggests a pre-litigation transfer.
  6. Bankruptcy fire-sale — not present. There is no indication of bankruptcy proceedings for any of the assignors.
  7. Privateering — unclear. There is no information in the provided text to suggest that an operating company transferred the patent to an NPE for assertion on its behalf.
  8. Defensive aggregator (anti-NPE) — not present. The chain does not end with any known defensive aggregators.

Verdict

NPE — moderate confidence

The presence of cascading transfers between two entities (Pyromart Inc. and Titan International Technologies Ltd.) in a short timeframe (2021, 2023, 2024), coupled with a transfer to the current assignee (Titan International Technologies Ltd.) occurring shortly before litigation was filed in 2024, are moderate signals of NPE activity. Without more information about the business activities and corporate structures of these entities or the correspondents involved in the transfers, a higher confidence level cannot be reached.
