SHARP KABUSHIKI KAISHA
SHARP KABUSHIKI KAISHA's patent strategy reveals a strong, albeit fluctuating, focus on communications, with Wireless Networks and Pictorial / Video Communications together accounting for over 50% of its portfolio. While Wireless Networks saw a significant 32.4% YoY growth in 2024, the dramatic 73.6% decline in Integrated Circuit Layout & Arrangement patents in 2024, followed by a near cessation of filings in 2025 and so far in 2026, indicates a surprising and rapid shift away from core semiconductor design, contrasting with an emerging focus on Liquid Crystal & Optical Modulators, which saw an 85.7% YoY growth in 2026 (partial year data).
