常見問題

涵蓋哪些專利局?

全球申請 — USPTO、EPO、WIPO PCT、JPO、KIPO、CNIPA 與主要國家局。搜尋執行於統一的語意專利索引上。

可以依申請人或發明人篩選嗎?

將其作為自然語言查詢的一部分傳入(例如 assignee:Tesla 電池熱管理)。語意索引可在查詢字串中解析實體式篩選。

可以依日期範圍篩選嗎?

可以。start_date / end_date(YYYY-MM-DD)依申請或公開日期篩選。

與 USPTO 直接搜尋相比定價如何?

USPTO 的公開搜尋免費但僅支援關鍵字,沒有語意排序。本 API 以每次呼叫 80 點(約 $0.08 使用者成本)執行跨司法管轄區的語意搜尋 — 在需要排序、可供 LLM 使用的結果時非常有用。
