NPE / troll-pattern signals
- Shell-entity transfer — Not present. The assignment is from the inventor to an operating company.
- Known asserter in the chain — Not present. Leonhard Kurz Stiftung & Co KG is an operating company and not listed as a known asserter.
- Repeat correspondent across the chain — Not present. There is only one recorded assignment in the chain (Reel 059491/0530).
- Cascading transfers — Not present. There is only one recorded assignment.
- Pre-litigation transfer — Not present. The only recorded assignment (Reel 059491/0530, executed 2022-07-26) occurred before the patent was granted on 2025-02-11. While Google Patents lists a "First worldwide family litigation filed" and a PTAB case (PGR2026-00011), these events are after the patent issuance and the assignment, meaning the assignment itself was not pre-litigation.
- Bankruptcy fire-sale — Not present. Leonhard Kurz Stiftung & Co KG appears to be an active, operating company.
- Privateering — Not present. No evidence in the assignment records or public information suggests this pattern.
- Defensive aggregator (anti-NPE) — Not present. The current owner is an operating company, not a defensive aggregator.
Verdict
Operating-company assertion
The patent remains with the original assignee, Leonhard Kurz Stiftung & Co KG, which is an operating company that manufactures and sells products related to the patent's claims. There are no recorded assignments indicating a transfer to a shell entity or known NPE, nor are there other signals suggestive of a patent troll pattern.
