Company patents
SEOYON E-HWA CO., LTD.
SEOYON E-HWA CO., LTD. shows a surprising patent strategy with a strong, consistent focus on core automotive components like "Vehicle Seats & Accommodations" and "Vehicle Body Fittings," each representing 24.2% of its portfolio, despite significant year-over-year fluctuations such as a 200.0% increase in "Vehicle Seats & Accommodations" in 2024 followed by a 66.7% decline in 2025. While "Switches" saw a rapid 300.0% growth in 2024, its subsequent 100.0% decline in 2025 and zero patents so far in 2026 suggest a shifting priority away from this area, contrasting with the sustained, albeit volatile, investment in its primary automotive categories.
