Patent 11620634

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 single reassignment is from CardWare Inc. to CardWare Inc., not to a separate licensing-focused entity.
  2. Known asserter in the chain — not present. CardWare Inc. is not identified on public NPE lists as an asserter.
  3. Repeat correspondent across the chain — not present. RYAN S. KOWALCHUK of KOWALCHUK LAW PC appears as the correspondent for the single recorded assignment. There are no other assignments to compare against.
  4. Cascading transfers — not present. Only one reassignment is recorded, not multiple consecutive transfers.
  5. Pre-litigation transfer — unclear. While the patent family has litigation, there is only one recorded reassignment to the original assignee, not a transfer from an operating company to a separate entity right before litigation. It's unclear if the reassignment was specifically to enable litigation.
  6. Bankruptcy fire-sale — not present. No indication of bankruptcy proceedings for CardWare Inc.
  7. Privateering — not present. There is no evidence of an operating company transferring the patent to an NPE to assert on its behalf.
  8. Defensive aggregator (anti-NPE) — not present. The patent is currently assigned to CardWare Inc.

Verdict

Insufficient data. There is only one reassignment recorded, which is from CardWare Inc. to CardWare Inc.. This does not provide sufficient evidence to confidently classify CardWare Inc. as an NPE or to indicate a patent troll pattern. The litigation mentioned on Google Patents is against the patent family and doesn't explicitly link to CardWare Inc. as a high-frequency plaintiff or to any of the listed NPEs.
