Company patents
HITACHI HIGH-TECH CORPORATION
HITACHI HIGH-TECH CORPORATION's patent strategy is heavily concentrated in Material & Chemical Analysis (44.6% of its portfolio) and Electron / Ion Tubes & Discharge (32.4%), indicating a strong foundation in materials and semiconductor technologies. While Semiconductor Manufacturing Process showed rapid growth of +41.5% in 2024, suggesting an emerging focus, the significant year-over-year declines across most categories in 2025 and so far in 2026, such as Material & Chemical Analysis (-12.4% in 2025 and -60.5% so far in 2026) and Electron / Ion Tubes & Discharge (-65.7% so far in 2026), point to a potential shift in patenting priorities or a slowdown in new filings.
