CNIPA Patent Search

L0: One-Sentence Summary

Input a company name, drive the CNIPA pss-system patent search via Kimi WebBridge browser automation, and return a structured patent list.

L1: Overview

• Data source: CNIPA Patent Search and Analysis System (pss-system.cponline.cnipa.gov.cn)
• Auth: logged-in account (registration required — anonymous search redirects to login)
• Invocation: Kimi WebBridge browser automation (navigate + evaluate + CDP insertText)
• Prerequisites:
  • Kimi WebBridge daemon running
  • the user has logged into pss-system in the browser (login persists; log in once and reuse)

Account Registration

pss-system requires real-name registration (phone + SMS):

1. Open https://pss-system.cponline.cnipa.gov.cn/ in the browser
2. Click "注册" and complete real-name registration
3. Log in once — the browser keeps the session for later automation

L2: Procedure

1. Check the WebBridge daemon

~/.kimi-webbridge/bin/kimi-webbridge.exe status

If down or disconnected, start it: kimi-webbridge.exe start.

2. Navigate to pss-system

Write C:\tmp\cnipa-nav.json:

{
  "action": "navigate",
  "args": {
    "url": "https://pss-system.cponline.cnipa.gov.cn/",
    "newTab": true,
    "group_title": "专利检索"
  },
  "session": "cnipa-patent"
}

curl.exe -s -X POST "http://127.0.0.1:10086/command" \
  -H "Content-Type: application/json" \
  --data-binary "@C:\tmp\cnipa-nav.json" --max-time 30

Wait 5 seconds.

3. Confirm login, accept the disclaimer, enter search

Write C:\tmp\cnipa-agree.json:

{
  "action": "evaluate",
  "args": {
    "code": "(async function(){var txt=document.body.innerText||'';var hasLogout=txt.includes('退出');if(txt.includes('免责声明')){var btns=document.querySelectorAll('button.el-button--primary');for(var b of btns){if((b.innerText||'').replace(/\\s+/g,'')==='同意'){b.click();break;}}await new Promise(function(r){setTimeout(r,4000);});}txt=document.body.innerText||'';return JSON.stringify({url:location.href.slice(0,80),isSearch:txt.includes('常规检索'),inputs:document.querySelectorAll('input').length,hasLogout:hasLogout});})()"
  },
  "session": "cnipa-patent"
}
