Company patents

SK microworks Co., Ltd.

SK microworks Co., Ltd. appears to be strategically shifting its focus, as evidenced by a significant decline in its dominant 'Polymer Working & Compounding' category, which saw an 88.9% YoY drop so far in 2026, alongside a notable decline in 'Polymer Synthesis (Polycondensation)' (80.0% YoY drop so far in 2026), despite these two categories together representing over 99% of its total portfolio. This is surprising given the rapid growth observed in 'Layered Products (Laminates, Films)' (33.3% YoY in 2025) and 'Polymer Compositions' (50.0% YoY in 2025) in prior years, suggesting a potential re-evaluation of its core materials processing and formulation strategies.
