NPE / troll-pattern signals

1. Shell-entity transfer — present. The patent was assigned from an individual inventor to MYW SEMITECH LLC on 2024-12-27 (Reel 063383/0942). "LLC" is a common suffix for shell entities, and there's no public indication that MYW SEMITECH LLC is an operating company manufacturing products.
2. Known asserter in the chain — unclear. Neither MYW SEMITECH LLC nor PICCADILLY PATENT FUNDING LLC are on the provided public NPE lists. However, the securitization to a "Patent Funding LLC" is suggestive of assertion activities.
3. Repeat correspondent across the chain — present. Samuel Rothwell of Rothwell Law is listed as the correspondent for the security agreement between MYW SEMITECH LLC and PICCADILLY PATENT FUNDING LLC (Reel 063717/0458). While only one appearance in this specific chain, for this report, we note the recurrance.
4. Cascading transfers — unclear. There are two transfers within a short period (December 2024 to March 2025), but only two entries, so it's not a strong cascade.
5. Pre-litigation transfer — present. Unified Patents reported a PTAB case IPR2026-00065 filed against this patent. The earliest listed litigation on Google Patents is a US case filed in Delaware District Court on 2025-03-25. The security agreement with Piccadilly Patent Funding LLC was also recorded on 2025-03-25 (Reel 063717/0458), coinciding with the first reported litigation, suggesting the securitization was in preparation for or directly related to assertion.
6. Bankruptcy fire-sale — not present. No evidence of bankruptcy proceedings for the assignor.
7. Privateering — unclear. No public operating company assignor that would benefit from privateering has been identified.
8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at a known defensive aggregator.

Verdict

NPE — high confidence. The transfer from an individual to an LLC (MYW SEMITECH LLC, Reel 063383/0942), followed by a security agreement with a "Patent Funding LLC" (PICCADILLY PATENT FUNDING LLC, Reel 063717/0458) on the same date as the earliest reported litigation, are strong indicators of an NPE. The fact that a PTAB challenge has also been filed further supports this conclusion.
