Company patents
SIGMASENSE, LLC.
SigmaSense, LLC's patent strategy appears to be undergoing a significant shift, with a broad decline across most categories, including its dominant 'Input/Output & User Interfaces' (52.7% of portfolio), which saw a 50.0% decline in 2025. While 'Measurement (Non-specific)' showed a surprising 266.7% growth in 2024, this momentum was not sustained, and patenting activity has largely ceased across all categories so far in 2026, indicating a potential strategic pivot away from new patent filings.
