Company patents
PANASONIC CORPORATION
PANASONIC CORPORATION's patent strategy reveals a surprising lack of sustained focus, with its largest category, Batteries & Fuel Cells (33.3% of portfolio), experiencing significant volatility, including a 200.0% YoY increase in 2025 followed by a -100.0% YoY decline so far in 2026. This trend is mirrored across most categories, with many showing sharp year-over-year declines, suggesting a highly dynamic and potentially fragmented R&D approach rather than a concentrated effort on specific emerging technologies.
