The Patent Filer
Salvatore Pais worked as an aerospace engineer for the Naval Air Station Patuxent River and filed a series of extraordinary patents on behalf of the U.S. Navy between 2016 and 2020. The patents — including a "hybrid aerospace-underwater craft," a "high energy electromagnetic field generator," and a "room temperature superconductor" — describe technologies that, if functional, would explain many of the flight characteristics observed in documented UAP encounters.
The Navy defended the patents' viability to the U.S. Patent and Trademark Office, arguing that the technologies were operable — a position that would require either a genuine technological breakthrough or a deliberate strategic deception. Pais claimed in interviews that several of the technologies had been demonstrated.
The Pais Effect
The so-called "Pais Effect" — electromagnetic field rotation creating a quantum vacuum plasma field — is described in the patents as the mechanism behind the propulsion systems. Whether this represents genuine black-project technology being quietly disclosed through the patent system, or a misinformation effort, remains one of the more intriguing open questions in the UAP field. Pais has since left the Navy and has not spoken publicly about his work.
