Company patents
SHINKAWA LTD.
SHINKAWA LTD. shows a surprising patent strategy with a strong historical focus on core semiconductor manufacturing technologies like "Chip-to-Chip Interconnect (Bonding, Bumps)" (56.4% of portfolio) and "Welding & Soldering" (33.3% of portfolio), both of which saw significant growth in 2024 (+69.2% and +87.5% YoY respectively). However, a notable shift occurred in 2025, with sharp declines across nearly all categories, including a -59.1% drop in "Chip-to-Chip Interconnect" and an -80.0% drop in "Welding & Soldering," and so far in 2026, there are no patents filed in these major categories, suggesting a dramatic re-evaluation or pause in patenting activity.
