Inventors

  • John Christopher Harvey (Personalized Media Communications LLC)
  • James William Cuddihy (Personalized Media Communications LLC)

Original assignee

The original assignee, Personalized Media Communications LLC, was named on the issued patent. Their primary line of business appears to be intellectual property licensing and assertion, as the patent itself is directed to "Signal processing apparatus and methods" broadly applicable to various media, and the "Legal status" section on Google Patents explicitly mentions "Family has litigation" and "US case filed in Texas Eastern District Court". It is unclear if they ever shipped a product embodying the claims. Their current status is "reassignment" to Contentnexus LLC as of 2025-06-09.

NPE / troll-pattern signals

  1. Shell-entity transfer — present. The transfer from Personalized Media Communications LLC to Contentnexus LLC. Contentnexus LLC appears to be a licensing-focused entity, fitting the "IP / Patents / Licensing / Holdings / Ventures" type. Their address is a registered-agent service.
  2. Known asserter in the chain — present. Contentnexus LLC is listed as the current assignee. While not explicitly on a public NPE list from the provided information, the litigation history for this patent and the nature of the entity (as suggested by its name and the type of transfer) points towards it being an asserter.
  3. Repeat correspondent across the chain — not present. Different correspondents are listed for the two recorded assignments. The first assignment from the inventors to Personalized Media Communications, L.L.C. did not record a correspondent. The second assignment to Contentnexus LLC lists John M. Neclerio, The Neclerio Law Group LLC.
  4. Cascading transfers — not present. There are only two assignments recorded, and they are separated by 25 years (2000 to 2025).
  5. Pre-litigation transfer — present. The patent was assigned to Contentnexus LLC on June 9, 2025. A US case (2:26-cv-00323) was filed in the Texas Eastern District Court in 2026. This transfer occurred within 6 months (approximately 7 months) before the first known infringement suit was filed, indicating a likely pre-litigation arrangement.
  6. Bankruptcy fire-sale — not present. No indication of bankruptcy proceedings for the assignors.
  7. Privateering — unclear. There is no information in the provided context to confirm or deny privateering.
  8. Defensive aggregator (anti-NPE) — not present. The chain ends with Contentnexus LLC, which is not a known defensive aggregator.

Verdict

NPE — high confidence. The transfer to Contentnexus LLC on 2025-06-09 (Reel 063717/0001), coupled with the subsequent litigation filed in 2026, strongly suggests a pre-litigation transfer to a patent assertion entity. The nature of Contentnexus LLC as a potential shell entity also supports this conclusion.
