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
  2. Known asserter in the chain — not present
  3. Repeat correspondent across the chain — not present. The correspondent, MICHAEL BEST & FRIEDRICH LLP, appears only on reel 065166/0508 for the assignment from the inventors to Milwaukee Electric Tool Corporation.
  4. Cascading transfers — not present
  5. Pre-litigation transfer — unclear. While there is litigation noted for the patent family, the current assignment record predates the initial filing date of the application leading to US11857064. The assignment from the inventors to Milwaukee Electric Tool Corp. was executed between 2020-09-23 and 2020-10-20 and recorded 2023-10-10 (Reel 065166/0508), while the patent was granted on 2024-01-02. It's too early to confirm a pre-litigation transfer with high confidence as of the current date.
  6. Bankruptcy fire-sale — not present
  7. Privateering — not present
  8. Defensive aggregator (anti-NPE) — not present

Verdict

Insufficient data. The only recorded assignment is from the inventors to the original assignee, Milwaukee Electric Tool Corporation, prior to the patent's issuance. This is a standard practice and does not indicate NPE activity. No other transfers or strong NPE signals are present in the provided information or patent records.
