Assignment history

Inventors

• Gregory Ellis (Employer at time of filing not determinable from patent text or public records).

Original assignee

The original assignee on the issued patent is Individual. The patent later reassigned to Monster Color Carnival LLC on January 17, 2024. Monster Color Carnival LLC's primary line of business appears to be in retail-eating places, according to SEC filings, specifically SIC 5812. There is no clear indication that Monster Color Carnival LLC ships a product embodying the claims of US11235110; their publicly available information and SEC filings do not suggest a nexus to psychedelic delivery systems. As of March 9, 2026, the status of a company with a similar name, LUB LIQUIDATING TRUST, has its Exchange Act registration revoked. However, it's unclear if this is the same entity as Monster Color Carnival LLC.

NPE / troll-pattern signals

1. Shell-entity transfer — unclear. While "Monster Color Carnival LLC" does not immediately suggest a connection to vaporizer technology or pharmaceuticals, and public information on their primary business lists "Retail-Eating Places", there is no explicit evidence (e.g., registered-agent address, single-member LLC declaration) to definitively label it as a shell entity for patent assertion. The patent was originally assigned by the individual inventor, Gregory Ellis, to this LLC.
2. Known asserter in the chain — not present. Neither Gregory Ellis nor Monster Color Carnival LLC appear on public NPE lists from RPX Insurance or Unified Patents.
3. Repeat correspondent across the chain — not present. BRENT JOHNSON, P.A., is listed as the correspondent for the single recorded assignment. There is no indication of recurrence in this chain or across other tracked patents at this time.
4. Cascading transfers — not present. Only one assignment has been recorded for this patent.
5. Pre-litigation transfer — not present. The assignment was recorded on January 17, 2024. While an IPR was filed in 2025, it does not constitute infringement litigation.
6. Bankruptcy fire-sale — not present. There is no information to suggest the original assignee or the current assignee have undergone bankruptcy proceedings and sold this patent as part of those proceedings.
7. Privateering — not present. There is no indication of an operating company transferring this patent to an NPE for assertion against competitors.
8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at a known defensive aggregator.

Verdict

Insufficient data. While the business activities of the current assignee, Monster Color Carnival LLC (SIC 5812 - Retail-Eating Places), appear unrelated to the patent's subject matter of psychedelic delivery systems, there is only one recorded assignment (Reel 063539/0471 on 2024-01-17) and no other strong NPE signals like known asserters in the chain, repeat correspondents, or cascading transfers. Further, the patent was assigned from the individual inventor directly to this LLC, which is a common practice for inventors forming their own companies. Without more evidence, a high-confidence NPE verdict cannot be reached.
