Company patents
SOULBRAIN CO., LTD.
SOULBRAIN CO., LTD. demonstrates a dynamic patent strategy, with a surprising surge in "Batteries & Fuel Cells" patents, which grew by 650.0% in 2024, indicating an emerging focus despite a subsequent dip in 2025. While "Semiconductor Manufacturing Process" remains its largest category at 48.0% of its portfolio, the significant year-over-year fluctuations across its top categories, including a +237.5% growth in "Semiconductor Manufacturing Process" in 2025 and a +375.0% growth in "Coating & Surface Treatment" in 2025, suggest a highly adaptive and potentially opportunistic approach to patenting, with a notable decline in several pharma-biotech related categories in 2026 so far.
