    "inventor_name": "Michael Brady",
    "publication_year": 2006,
    "device_name": "Perendev Magnet Motor",
    "goal": "Provide a self-sustaining mechanical output (free energy) without an external power source.",
    "problem_addressed": "Lack of inexpensive, continuous energy source; desire for perpetual-motion-type power generation.",
    "concept_summary": "A magnetic repellent motor consisting of a rotor with permanent magnets and a surrounding stator with opposing permanent magnets. The magnetic fields are partially screened to concentrate flux in the gap, allegedly causing continuous rotation without external energy.",
    "detailed_description": "The patent describes a shaft rotating about its longitudinal axis, a first set of magnets mounted on the rotor and a second set mounted on the stator. The two sets interact magnetically, with partial magnetic shielding (e.g., PTFE or air gaps) to focus the magnetic field across the rotor-stator gap. The inventor marketed the device as a \"Permanent Magnet Machine\" claiming it could operate as a perpetual-motion motor, but the European Patent Office rejected the claim and the inventor was later convicted of fraud.",

        "The defendant offered the engine for sale, falsely telling prospective buyers that series production had already begun."
