NPE / troll-pattern signals

1. Shell-entity transfer — Present. The patent was assigned from an individual inventor to MYW SEMITECH LLC (Reel 062602/0833). MYW SEMITECH LLC is identified as a patent assertion entity (PAE) with a business focused on "advanced AI predictions and analytics on patent cases" and is currently involved in patent litigation against [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.). It does not appear to be a product-shipping company. Piccadilly Patent Funding LLC, the assignee in the security agreement, is a known patent litigation funder, and its address (c/o Corporation Service Company in Wilmington, DE) is a common registered agent address for shell entities.

2. Known asserter in the chain — Present. MYW SEMITECH LLC is actively asserting this patent in a lawsuit against Apple Inc. (1:25-cv-00504) in the District of Delaware. Search results clearly indicate its role as a patent assertion entity.

3. Repeat correspondent across the chain — Unclear. Ping-Jung Yang, the inventor and assignor, served as the correspondent for the first assignment (Reel 062602/0833). John M. Brighton of Wakefield IP Law is the correspondent for the second recording (Reel 064436/0677). There is no pattern of the same correspondent appearing on multiple unrelated assignments within this chain or across other known assertion campaigns from the provided data.

4. Cascading transfers — Not present. Only two recorded transfers are present, one being a security agreement. This does not indicate multiple consecutive assignments through chained LLCs in a short timeframe.

5. Pre-litigation transfer — Present. The patent security agreement between MYW SEMITECH LLC and PICCADILLY PATENT FUNDING LLC was executed on 2025-03-20 and recorded on 2025-03-25 (Reel 064436/0677). This date immediately precedes the filing of the infringement suit against Apple Inc. on April 23, 2025, strongly indicating that the security agreement was part of a pre-litigation funding arrangement to enable the assertion.

6. Bankruptcy fire-sale — Not present. There is no indication from the provided information that any assignor in the chain filed for bankruptcy and sold the patent as part of proceedings.

7. Privateering — Unclear. While MYW Semitech LLC is asserting the patent against Apple Inc., there is no explicit information or external reporting to suggest this transfer was made on behalf of an operating company against its competitors.

8. Defensive aggregator (anti-NPE) — Not present. The patent is currently held by MYW SEMITECH LLC with a security interest from Piccadilly Patent Funding LLC; neither are defensive aggregators.

Verdict

NPE — high confidence

MYW SEMITECH LLC is a patent assertion entity, actively engaged in patent litigation against Apple Inc. with this patent. The transfer from the individual inventor to MYW SEMITECH LLC (Reel 062602/0833) signifies a shell-entity transfer. Furthermore, the patent security agreement with Piccadilly Patent Funding LLC (Reel 064436/0677) immediately prior to the litigation filing date (April 23, 2025) is a strong indicator of a pre-litigation financing strategy.
