Patent 9164942

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 transferpresent. The transfer from ETRON TECHNOLOGY, INC. to VALUECREATION TECHNOLOGY, INC. (Reel 072191/0373) and then to WECREVENTION, INC. (Reel 072228/0495) suggests shell entities. VALUECREATION TECHNOLOGY, INC. and WECREVENTION, INC. do not appear to be product-shipping companies, and "VALUECREATION TECHNOLOGY" and "WECREVENTION" sound like holding companies. WECREVENTION, INC. is noted as being in Texas.

  2. Known asserter in the chainunclear. While the pattern of transfers suggests NPE activity, neither VALUECREATION TECHNOLOGY, INC. nor WECREVENTION, INC. are explicitly identified as known high-frequency NPEs in the provided public lists (Acacia Research Corp, Marathon Patent Group, etc.) or in the provided text. However, the patent is currently involved in litigation, including an IPR case (IPR2026-00239) and district court cases in the Texas Western and Eastern District Courts, which are common venues for NPE assertions.

  3. Repeat correspondent across the chainnot present. The correspondent information is not available in the provided text for any of the assignment records, so this signal cannot be evaluated.

  4. Cascading transferspresent. There are two consecutive assignments within a short timeframe (executed 2023-05-18, recorded 2025-09-08; executed 2025-05-01, recorded 2025-09-11). The first transfer to VALUECREATION TECHNOLOGY, INC. and then quickly to WECREVENTION, INC. within roughly two years, with both recordings occurring in September 2025, fits this pattern (Reel 072191/0373 and Reel 072228/0495).

  5. Pre-litigation transferpresent. The assignment to WECREVENTION, INC. was executed on 2025-05-01 and recorded on 2025-09-11 (Reel 072228/0495). Unified Patents indicates that US cases were filed in the Texas Eastern and Western District Courts starting in 2025, with specific case numbers (e.g., 7:25-cv-00458, 2:25-cv-01040, 2:25-cv-01008, 2:25-cv-00951). This timing suggests the transfer to WECREVENTION, INC. may have been made in preparation for these assertions.

  6. Bankruptcy fire-salenot present. There is no indication in the provided text that Etron Technology Inc. filed for bankruptcy.

  7. Privateeringunclear. While Etron Technology Inc. transferred the patent, there is no direct evidence in the provided information (such as SEC filings or specific reports) to confirm that VALUECREATION TECHNOLOGY, INC. or WECREVENTION, INC. are asserting on behalf of Etron Technology Inc. against its competitors.

  8. Defensive aggregator (anti-NPE)not present. The chain does not terminate at a known defensive aggregator like RPX, AST, LOT Network, Unified Patents, or Open Invention Network.

Verdict

NPE — high confidence

This verdict is based on several strong signals: the presence of cascading transfers between entities with non-operating-company names (VALUECREATION TECHNOLOGY, INC. and WECREVENTION, INC.), and the clear timing of a pre-litigation transfer to WECREVENTION, INC. just prior to the initiation of multiple infringement suits in known NPE-favorable jurisdictions in Texas in 2025. These patterns strongly indicate that the patent has been transferred for assertion purposes.
