Company patents
HI LLC
HI LLC's patent strategy shows a surprising shift away from its core focus, with Medical Diagnostics & Surgery, which constitutes 75.3% of its portfolio, experiencing a significant decline of -74.2% in 2025 and -62.5% so far in 2026. While Photometry / Spectrometry saw a rapid emergence with 133.3% growth in 2024, most categories, including Electrical Measurement (-100.0% in 2025) and Optical Elements & Systems (-100.0% in 2025), indicate a broad de-prioritization of patenting activity across its portfolio.
