Defendant
1 case as defendant.
Gregory Ellis is an individual patent owner, not a traditional operating company. His primary entity for patent ownership is Monster Color Carnival, LLC (MCC), where he serves as the organizer and sole member. Publicly available information does not specify a headquarters, founding year for MCC, or traditional corporate size metrics such as employee count or revenue.
Gregory Ellis holds U.S. Patent No. 11,235,110, titled "Delivery System For Ayahuasca-Like Substances," with him listed as the inventor. The patent broadly covers a delivery device and vaporizable formulations for psychedelic substances. There is no public indication that Gregory Ellis or Monster Color Carnival, LLC manufactures, sells, or provides any products or services related to this patent.
In terms of patent litigation, Gregory Ellis maintains a defensive posture. He is currently a defendant in a single tracked case, an inter partes review (IPR) proceeding initiated by Porta Sophia before the Patent Trial and Appeal Board (PTAB). This indicates that his patent is being challenged rather than being actively asserted against other entities.
The notable case is Porta Sophia v. Gregory Ellis (IPR2025-01460), filed on August 22, 2025. Porta Sophia, a non-profit organization dedicated to building a library of psychedelic prior art, is challenging U.S. Patent No. 11,235,110 for anticipation and obviousness. The challenge specifically cites a 2012 forum post as prior art against the patent's claims related to DMT delivery, aligning with Porta Sophia's mission to protect the public domain from overly broad patents in the psychedelic field.
Porta Sophia filed an Inter Partes Review petition against Gregory Ellis concerning US Patent 11235110, which the PTAB did not institute for procedural reasons.
