NPE / troll-pattern signals

  1. Shell-entity transfer — Not present. The transfers reflect a security agreement and its subsequent release involving the operating company Netlist Inc. and a financing entity, SVIC No. 28 New Technology Business Investment L.L.P..
  2. Known asserter in the chain — Not present. SVIC NO. 28 NEW TECHNOLOGY BUSINESS INVESTMENT L.L.P. is not identified as a known patent assertion entity, and Netlist Inc. is an operating company.
  3. Repeat correspondent across the chain — Present. DLA PIPER LLP (US) appears as the correspondent for both the 2015-11-20 security agreement (Reel 036814/0670) and the 2023-11-20 release of security interest (Reel 062635/0681).
  4. Cascading transfers — Not present. The two recorded events are related to a single security interest transaction and its release over an eight-year period, not multiple consecutive transfers in a short timeframe.

Verdict

Operating-company assertion
The assignment records clearly indicate that the patent was subject to a security agreement and subsequently returned to Netlist Inc., an operating company. Netlist Inc. is actively involved in litigation concerning this patent, as shown by multiple pending cases filed in 2025. This pattern is consistent with an operating company asserting its intellectual property.
