Patentability Search Guide: How to Determine If Your Invention Can Be Patented

Introduction: Evaluating Your Invention

Before spending time and money filing a patent application, you must answer a vital question: Is the invention patentable?

A patentability search (or novelty search) is an in-depth audit of patent databases, scientific journals, and products globally to see if similar concepts exist. This guide explains how to conduct a search and assess your invention.

1. The Three Core Patentability Criteria

To be patentable under the Patents Act 1970, your invention must meet three criteria:

Novelty: The invention must not have been disclosed in any public prior art anywhere in the world.

Inventive Step (Non-Obviousness): The invention must feature a technical advancement or economic significance that is not obvious to a person skilled in the art.

Industrial Applicability: The invention must be capable of being made or used in an industry.

2. Step-by-Step Search Methodology

1. Define Key Concepts: Break down your invention into its core functional components and keywords.

2. Patent Database Searches: Use tools like Google Patents, Espacenet, USPTO, and WIPO PATENTSCOPE.

3. Scientific & Prior Art Searches: Search academic publications, product catalogs, and e-commerce websites.

4. Analyze Results: Check if your invention’s claims are fully disclosed in any single reference or obvious combination of references.

Frequently Asked Questions

1. Can I perform a patentability search myself?

Yes, anyone can run basic keyword searches. However, hiring a professional patent agent is recommended to interpret complex patent claims and classifications.

2. Does prior art include foreign-language publications?

Yes. Prior art is global. A document published in Chinese or German before your filing date counts as prior art and can defeat your patent’s novelty.

3. What is the difference between FTO and patentability searches?

A patentability search checks if your invention is new enough to get a patent. An FTO search checks if your product infringes active, granted patents owned by others.
