Company patents
TES CO., LTD
TES CO., LTD's patent strategy shows a strong, recent surge in core semiconductor and materials technologies, with "Semiconductor Manufacturing Process" patents growing by an astounding +233.3% in 2025 to 20 patents, representing 47.7% of its portfolio, and "Coating & Surface Treatment" also seeing significant growth of +166.7% in 2024. However, the sharp decline in patent filings across most categories so far in 2026, including a 95.0% drop in "Semiconductor Manufacturing Process" and a 90.0% drop in "Coating & Surface Treatment," suggests a potential shift or slowdown in patenting activity this year, though 2026 data is partial.
