# PatentPulse

> Global patent and IP intelligence API. USPTO + EPO + WIPO + JPO patent search, pharma patent cliff calendar, freedom-to-operate analysis, company portfolio intelligence, prior art search, standard essential patents (SEP), competitor R&D intelligence from patent filings, and USPTO trademark clearance — all via x402 micropayments on Base.

## What This Is

PatentPulse is a pay-per-query API that synthesizes USPTO PatentsView data, global patent context (EPO/WIPO/JPO), and real-time intelligence into structured, actionable patent and IP intelligence. Every response is generated by Claude.

All endpoints support `?lang=` for any language — Claude responds natively.

## Payment

All endpoints require x402 micropayment (USDC on Base mainnet).
Protocol: x402 | Network: eip155:8453 | Asset: USDC
Payment address: 0x50ab2018c06c6E4eAA9BA52057Eb55eD284912fc

To use: send a GET request without a PAYMENT-SIGNATURE header to receive a 402 response with payment requirements. Sign the payment and retry.
