Introduction

Searching patents in India used to mean juggling multiple government portals, downloading CSV files, and manually sifting through thousands of records. PatentLab changes that by integrating directly with IP India's InPASS (Indian Patent Advanced Search System) — giving inventors, attorneys, and businesses a single, AI-powered interface to search and analyse India's official patent database.

In this guide, we'll explain exactly what InPASS is, how PatentLab connects to it, and why this integration matters for your patent strategy.

What is InPASS?

InPASS is the official patent search portal maintained by the Indian Patent Office (IPO), part of IP India. It provides access to:

All patent applications filed with the Indian Patent Office since 1856
Granted patents, abandoned applications, and pending applications
Full-text search by title, abstract, inventor, applicant, and IPC classification
Official legal status — whether a patent is pending, granted, lapsed, or revoked

For patent professionals, InPASS is the authoritative source for Indian prior art. For inventors, it's the starting point for any freedom-to-operate analysis.

The challenge? InPASS is functional but not user-friendly. Queries require specific syntax knowledge, results aren't ranked by relevance, and there's no AI to help you interpret what you find.

How PatentLab Bridges the Gap

PatentLab sits on top of InPASS and adds a layer of AI intelligence:

1. Natural Language Search

Instead of crafting Boolean queries like TTL/(hydrogen* AND fuel AND cell*), you simply type:

"Search for patents related to hydrogen fuel cells for electric vehicles filed in India after 2018"

PatentLab's AI translates this into the correct InPASS query syntax, executes it, and returns ranked results.

2. Real-Time Results from Official Data

All results come directly from InPASS — the same data that patent examiners at the Indian Patent Office use. PatentLab doesn't cache or delay results; you get live, authoritative data.

3. AI-Powered Analysis

Once results arrive, PatentLab's AI:

Summarises each patent in plain English
Highlights key claims relevant to your invention
Identifies potential conflicts with your proposed claims
Calculates novelty risk — how similar the prior art is to your invention

4. Cross-Database Comparison

Beyond InPASS, the same search simultaneously queries:

USPTO (US Patent and Trademark Office)
WIPO PatentScope (PCT applications)
Espacenet (European Patent Office)

This gives you a complete global picture, not just Indian prior art.

Using the InPASS Button

On the PatentLab search results page, you'll find an "Open in InPASS" button next to each Indian patent result. Clicking it takes you directly to the official IPO record for that patent — with all the legal and bibliographic details from the government source.

This is especially useful when you need to:

Download official PDF documents for a patent
Verify the exact legal status before filing a response
Share official source links with clients or in an FER reply

Practical Example: Prior Art Search Before Filing

Let's say you've invented a new water purification technology using graphene membranes and want to file a provisional application in India.

Step 1: Enter your invention description in PatentLab's search box in natural language.

Step 2: PatentLab queries InPASS, USPTO, and WIPO simultaneously and returns ranked results within seconds.

Step 3: The AI highlights the 3 most relevant prior art documents and explains how your invention differs from each.

Step 4: You save the search report, which your patent attorney uses to refine the claims before filing.

Step 5: When the FER arrives months later, the same prior art analysis helps your attorney draft a strong reply — with PatentLab's AI FER Response Drafting tool pre-loaded with the relevant prior art context.

Why This Matters for Indian Inventors

India's patent ecosystem has grown dramatically. The Indian Patent Office received over 89,000 patent applications in the fiscal year 2024–25 — a record. With this volume, thorough prior art search is more important than ever.

PatentLab's InPASS integration ensures that Indian inventors have the same quality of patent intelligence tools that large corporations and law firms have — at a fraction of the cost.
