Inventors
- John Christopher Harvey: Employer at time of filing not determinable from the patent document.
- James William Cuddihy: Employer at time of filing not determinable from the patent document.
No unusual patterns regarding inventors departing the original assignee within 12 months of filing are determinable from the provided information.
Original assignee
The original assignee, Personalized Media Communications LLC, does not appear to have shipped a product embodying the claims directly. Their primary line of business, based on public information and previous litigation history (as noted in the litigation summary), appears to be patent licensing and enforcement. Their current status is "Active" as an assignee in the record until 2025, when the patent was reassigned.

NPE / troll-pattern signals
Shell-entity transfer — present.
- 2025-06-09 (executed) / recorded 2025-06-09 — Reel 063063/0187: The transfer to CONTENTNEXUS LLC. ContentNexus LLC, as the plaintiff in recent litigation (2:26-cv-00323), does not appear to ship products embodying the claims. The name "ContentNexus LLC" suggests a licensing or holding entity.
Known asserter in the chain — present.
- 2000-09-22 (executed) / recorded 2000-09-22 — Reel 011409/0002: Personalized Media Communications, L.L.C. (PMC) is a known high-frequency plaintiff/asserter as indicated in the litigation summary.
- 2025-06-09 (executed) / recorded 2025-06-09 — Reel 063063/0187: ContentNexus LLC has recently filed infringement suits, indicating it is an asserter.
Repeat correspondent across the chain — not present.
- John M. Calimafde of Hopgood, Calimafde, Kalil & Judlowe handled the 2000 assignment.
- Matthew J. Rizzolo of RIZZOLO LAW FIRM, PLLC handled the 2025 assignment. These appear to be different correspondents.
Cascading transfers — not present. There is only one transfer between the original assignee and the current assignee, with a 25-year gap between the filing date and the first recorded assignment, and then another 25-year gap until the second.
Pre-litigation transfer — present.
- 2025-06-09 (executed) / recorded 2025-06-09 — Reel 063063/0187: The assignment to ContentNexus LLC occurred on June 9, 2025, which is less than 6 months before the first infringement suit filed on April 22, 2026, against Red Bull GMBH (2:26-cv-00323). This strongly suggests the transfer was arranged to enable assertion.
Bankruptcy fire-sale — not present. No indication of bankruptcy in the assignment records or general patent information.
Privateering — unclear. While Personalized Media Communications, L.L.C. was the original assignee and ContentNexus LLC is now asserting the patent, there is no explicit evidence from SEC filings or other public coverage to definitively establish a privateering arrangement where an operating company transfers to an NPE to assert on its behalf against competitors.
Defensive aggregator (anti-NPE) — not present. The chain does not end at a known defensive aggregator.
Verdict
NPE — high confidence
This verdict is based on multiple strong signals: the presence of a known asserter (Personalized Media Communications, L.L.C.) as the original assignee, the transfer to another entity (CONTENTNEXUS LLC) which has immediately initiated litigation, and the clear pre-litigation transfer on 2025-06-09 (Reel 063063/0187) occurring less than a year before the first known infringement suit (2:26-cv-00323) was filed. The current assignee, CONTENTNEXUS LLC, also exhibits characteristics of a shell entity, further supporting this conclusion.
