NPE / troll-pattern signals

  1. Shell-entity transferpresent. The transfer from Panasonic Corporation to Optis Wireless Technology, LLC (Reel 031440/0173) is a strong indicator. Optis Wireless Technology, LLC has been identified in litigation as a patent assertion entity and does not appear to ship products embodying the claims. The correspondent, Scott C. Kelly, is also associated with known NPEs.
  2. Known asserter in the chainpresent. Optis Wireless Technology LLC is a known patent assertion entity (NPE), as evidenced by its extensive litigation history.
  3. Repeat correspondent across the chainpresent. Scott C. Kelly of Kelly & Kelley, LLP (Reel 031440/0173) is a repeat correspondent in patent assignment records for known NPEs. Jennifer S. Liu of Ropes & Gray LLP also appears on multiple security interest filings (Reel 031505/0130, Reel 031527/0273, Reel 036329/0815) related to Optis Wireless Technology, LLC, consistent with financing arrangements often seen with NPEs.
  4. Cascading transfersnot present. While there are multiple transfers related to financing, the primary ownership transfer to Optis Wireless was a single step, not a chain of LLCs.
  5. Pre-litigation transferunclear. The "Family has litigation" section on Google Patents indicates first worldwide family litigation filed, but a specific date tied to this patent or its direct family members within 6 months of the 2014-02-23 assignment is not readily available in the provided text.
  6. Bankruptcy fire-salenot present. Panasonic Corporation, the original assignee, is an active operating company.
  7. Privateeringunclear. While Panasonic transferred the patent to Optis, there's no explicit information in the provided text to confirm if Optis is asserting on Panasonic's behalf against competitors.
  8. Defensive aggregator (anti-NPE)not present. The chain does not terminate at a known defensive aggregator.

Verdict

NPE — high confidence

The transfer from Panasonic Corporation to Optis Wireless Technology, LLC (Reel 031440/0173), coupled with Optis Wireless Technology LLC being a known patent assertion entity and the recurrence of a correspondent attorney associated with NPEs, strongly indicates NPE activity. The securitization events following the assignment to Optis also align with the financing models often employed by NPEs.
