Overview

The TIPO (Taiwan Intellectual Property Office) API provides access to Taiwan's patent search system, allowing you to retrieve patent data, search by keyword, and look up inventor or applicant information for Taiwanese patents. Authentication uses an API key that you request from TIPO's open data platform. It is a good starting point for researchers interested in Asia-Pacific patent landscapes.

💡

Beginner Tip

Register for an API key at cloud.tipo.gov.tw and pass it as the "apikey" query parameter in every request. Start by querying a simple keyword search on patent titles to understand the response structure before building complex filters.

Available Data

Use case: Integrate taiwan patent search system api data into web and mobile applications
TIPO data via REST API
JSON-formatted response data
Requires API key authentication

Example Response

JSON Response 
{
  "status": "success",
  "data": {
    "result": "Data from TIPO",
    "description": "Taiwan patent search system api",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

applyNo Taiwan patent application number assigned when the patent was filed
publicNo Publication number assigned when the patent application was published
title Patent title, typically in Traditional Chinese
applicant Name of the person or organization that applied for the patent
applyDate Date the patent application was filed (YYYY-MM-DD format)
ipcCode International Patent Classification code categorizing the technology area of the patent

Implementation Example 

const url = "https://tiponet.tipo.gov.tw/Gazette/OpenData/OD/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized or "invalid apikey" The API key was not passed correctly or is not yet activated
✓ Ensure the key is passed as a query parameter named "apikey" (lowercase); check the TIPO portal to confirm your key is active
Response fields are in Traditional Chinese TIPO is a Taiwanese government API; many field values are in Chinese by default
✓ Use a translation API alongside TIPO responses, or filter for fields that contain numeric data (dates, patent numbers) which are language-neutral
Empty results for English keyword search Patent records are primarily indexed in Chinese; English keyword searches may not match Chinese text
✓ Try translating your keyword to Traditional Chinese before querying, or use IPC classification codes which are language-neutral
