United States Trademark API – Unified Access
Signa enhances USPTO data with AI-powered similarity matching, 10x higher rate limits (10,000/hr), normalized data format, and real-time updates.
Complex integration, limited features
While the USPTO provides API access, it has rate limits (1,000 requests/hour), inconsistent data formatting, and no built-in similarity matching. Building robust trademark search requires implementing your own fuzzy matching, phonetic algorithms, and data normalization.
