About

Smart Patent Pro

Features
Read full description

Smart Patent Pro brings an AI-assisted patent workflow to your phone. Draft patent applications, explore invention ideas, screen freedom-to-operate risk, run a mock examination, and translate patent documents — across English, Simplified Chinese,Traditional Chinese, Korean, and Japanese. Every output is a first-pass draft, a screening signal, or a qualitative assessment — built to be reviewed with a qualified patent attorney or agent. Smart Patent Pro does not provide legal advice and does not guarantee patentability, grant, validity, or non-infringement. SIX TOOLS IN ONE APP • Patent drafting — generate a structured first draft of an application from your invention description, with claims, background, and detailed description to refine. • Patent discovery (TRIZ) — turn a rough idea into candidate invention directions using a structured ideation method, with a qualitative go/investigate/decline read. • Patent strategy & portfolio layout — get suggestions for how to frame and lay out protection around an invention. • Mock examination / pre-filing review — a simulated examiner pass that surfaces possible objections so you can strengthen a draft before filing. It is a practice exercise, not a prediction of the real examination result. • FTO (freedom-to-operate) triage — a first-pass, qualitative read on infringement risk to help you prioritize where to look closer with counsel. • Patent document translation — translate patent text between the five supported languages with patent-aware handling. WORKS IN FIVE LANGUAGES English · 简体中文 · 繁體中文 · 한국어 · 日本語. The interface and AI output follow your selected language. SUBSCRIPTION PLANS Smart Patent Pro is an auto-renewing subscription.
