Their Claims
Salvatore Pais is the inventor behind five patent applications filed on behalf of the US Navy between 2015 and 2019 that describe technologies far beyond the current state of publicly known physics. Central to all five patents is a theoretical concept Pais calls the "Pais Effect" — the generation of extremely high electromagnetic energy fluxes through the controlled motion of electrically charged matter subjected to accelerated vibration and/or accelerated spin via rapid acceleration transients. Pais claims this effect can interact with the quantum vacuum energy state to produce phenomena including inertial mass reduction and room-temperature superconductivity.
The Five Patents
-
US10,144,532 — "Craft Using an Inertial Mass Reduction Device" (filed 2016, granted December 2018): Describes a craft capable of extreme speeds in air, water, and space by reducing its inertial mass through a high-energy electromagnetic field generator. This is the most discussed of the patents and the one that was initially rejected by the USPTO before Navy intervention.
-
US10,135,366 — "Electromagnetic Field Generator and Method to Generate an Electromagnetic Field" (granted November 2018): Describes a device to generate high-energy electromagnetic fields capable of interacting with the vacuum energy state.
-
US10,322,827 — "High Frequency Gravitational Wave Generator" (granted June 2019): Describes a device for generating high-frequency gravitational waves using accelerated electrostatic charge carriers on a vibrating membrane.
-
Room-Temperature Superconductor (published 2019): A patent application describing a room-temperature superconductor enabled by the Pais Effect. If viable, this would represent one of the most consequential breakthroughs in materials science.
-
"Plasma Compression Fusion Device" (published 2019, later abandoned): Describes a compact fusion reactor based on dynamic fusioning of pellets compressed by an electromagnetic field. This patent was ultimately abandoned.
The Pais Effect
In Pais's own formulation, the Pais Effect is "the Generation of Extremely High Energy Densities, produced by the Accelerated Vibration (and/or the Accelerated Spin) of a Non-Equilibrium Plasma — When Driven Far-From-Equilibrium at a 'particular' vibrational frequency the Plasma will experience Anomalous Behavior which can cause the Schwinger Limit to be achieved, thereby resulting in the Ripping apart / Tearing up of the Spacetime Fabric at the Quantum level."
Pais views his work as offering "a new perspective on old physics" — new interpretations of existing knowledge that can lead to technological breakthroughs. He has consistently maintained that the physics underlying his patents is sound and that the inventions are "not a bluff."
Key Quotes
"The Pais Effect comprises the generation of extremely high electromagnetic energy fluxes generated by controlled motion of electrically charged matter subjected to accelerated vibration and/or accelerated spin, via rapid acceleration transients, which can locally interact with the Vacuum Energy State." — Salvatore Pais, patent filings and peer-reviewed papers
"It is possible to reduce the inertial mass and hence the gravitational mass, of a moving object by the application of an abrupt perturbation." — Salvatore Pais, US Patent No. 10,144,532
"China is already investing significantly in this area and would prefer we hold the patent as opposed to paying forever more to use this revolutionary technology." — Dr. James Sheehy, Navy CTO, letter to USPTO patent examiner, December 15, 2017
"The examiner essentially stated that the power required to make the craft fly would be three orders of magnitude greater than a neutron star." — Summary of patent examiner Philip J. Bonzell's rejection of the inertial mass reduction patent
"The concept of reducing mass is counter to all known physics, starting with Einstein's theory of special relativity." — Terry Matilsky, emeritus professor of astronomy and physics, Rutgers University
Key Arguments & Evidence They Cite
- Patent filings accepted by USPTO: Despite initial rejection, the US Navy successfully argued for patent approval, with the Navy CTO personally intervening to certify that experiments were underway. The patents were granted, making them official US government intellectual property.
- Chinese competition: Navy CTO James Sheehy's December 2017 letter to the patent examiner argued that China was investing significantly in similar technologies and that the US needed to secure patent rights. This geopolitical framing was reportedly a significant factor in overcoming the examiner's objections.
- Peer-reviewed publications: Pais published papers on his theoretical framework in peer-reviewed journals, which he cited as evidence of scientific legitimacy.
- $508,000 in Navy testing: NAWCAD spent over $500,000 from 2016 to 2019 testing the core Pais Effect concept, indicating the Navy took the claims seriously enough to invest significant resources.
- Quantum vacuum energy interaction: Pais's theoretical framework proposes that the Pais Effect can interact with quantum vacuum fluctuations (zero-point energy), connecting his work to established quantum field theory concepts while extending them into uncharted territory.
- Vacuum energy as the "Fifth State of Matter": Pais frames the quantum vacuum as "Quintessence" — an active energy field that can be manipulated under the right conditions, linking his work to broader Zero Point Energy research.
The Patent Rejection and Navy Intervention
The story of how these patents were granted is itself significant. Patent examiner Philip J. Bonzell initially rejected the inertial mass reduction patent, calculating that the power requirements described were "three orders of magnitude greater than a neutron star" — physically impossible with any known or foreseeable technology. Bonzell questioned how anyone with ordinary skill in engineering could construct the device as described.
In response, Navy CTO Dr. James Sheehy wrote to the USPTO on December 15, 2017, acknowledging that the technology was "beyond the state of the possible, at least at present," but arguing that the Navy had begun experiments, that the inventor believed it was operable, and — critically — that China was already investing significantly in similar research. Sheehy stated the Navy "would prefer we hold the patent as opposed to paying forever more to use this revolutionary technology."
Several months after Bonzell's "final rejection," the patent was granted.
Testing and Results
NAWCAD conducted experiments from 2016 to 2019, spending approximately $508,000 attempting to demonstrate the Pais Effect. According to documents obtained through FOIA requests and reported by The War Zone, NAWCAD ultimately concluded that the Pais Effect could not be proven. No working prototype of any of the five patented inventions was ever produced during this testing period.
In January 2023, the patents expired due to non-payment of maintenance fees by the Navy, which some observers interpreted as the Navy's final verdict on the technology's viability. Others have speculated this may have been a deliberate decision to move the technology into classified programs where patents would be unnecessary.
Career Trajectory
Pais's career movements after the patents attracted attention:
- He left NAWCAD in June 2019, transferring to the US Navy's Strategic Systems Programs (SSP)
- In January 2021, he transferred to the United States Air Force
- As of 2025, he reportedly works for the United States Space Force and is based in Bonn, Germany
These transfers — from a naval aviation research center to strategic programs to the Air Force to the Space Force — have fueled speculation about whether his work continued in classified settings.
The Counterargument
- Physics community skepticism: Multiple physicists consulted by journalists described the patent language as pseudoscientific. The patents use terminology and make claims that do not align with established physics, and no experimental evidence has validated the Pais Effect.
- Energy requirements: Patent examiner Bonzell's calculation that the required power exceeds a neutron star by three orders of magnitude represents a fundamental physics objection — not merely an engineering challenge but a theoretical impossibility under known physics.
- Failed testing: The Navy's own $508,000 testing program at NAWCAD from 2016 to 2019 failed to demonstrate the Pais Effect, which is the foundational concept underlying all five patents.
- Patent expiration: The Navy allowed the patents to expire in January 2023 by not paying maintenance fees, which critics interpret as an institutional acknowledgment that the technology does not work.
- Disinformation hypothesis: Some analysts have suggested the patents may constitute deliberate disinformation — filed to mislead strategic adversaries (particularly China) about the direction of American defense research. The explicit invocation of Chinese competition in the patent approval process lends some weight to this interpretation. Pais himself rejected this theory, stating his patents were "not a bluff."
- Institutional incentives: Skeptics note that patent examiners do not typically evaluate whether an invention works — only whether it is novel and adequately described. The Navy CTO's intervention was unusual and may have reflected institutional or strategic motivations rather than scientific confidence.
