Company patents
WiTricity Corporation
WiTricity Corporation's patent strategy shows a surprising and significant decline across nearly all categories, including its core focus areas like Power Distribution & Storage (87.7% of portfolio, with a -71.4% YoY decline so far in 2026) and Electric Vehicle Propulsion (63.1% of portfolio, with a -66.7% YoY decline so far in 2026). This widespread reduction, even in historically strong areas, suggests a substantial shift in their intellectual property investment or a strategic pivot away from broad patenting efforts.
