Company patents

Hunter Engineering Company

Hunter Engineering Company shows a surprising shift away from several key technology areas, with Radar / Sonar / Lidar patents declining by 100.0% year-over-year in 2026 (so far) and Image Processing also seeing a 100.0% decline in 2026 (so far), despite these categories representing 28.9% and 17.8% of their total portfolio, respectively. While Length / Distance Measurement remains their largest category at 33.3% of their portfolio, its recent decline of 25.0% in 2026 (so far) suggests a broader re-evaluation of their core patenting efforts, with Vehicle Tires being a notable exception, showing strong growth of +100.0% in 2024 and +50.0% in 2025 before a partial decline in 2026.
