How to Conduct a Patentability Search – A Step-by-step guide for start-ups and inventors
If you’ve developed a new invention or come up with a unique idea, “What if someone else already had your idea and you just didn’t know it yet?” That’s why conducting a patentability search is one of the most important first steps to protect your idea. This process involves examining existing patents and public information to determine whether your concept is genuinely novel.
Without a thorough patentability search, you risk spending time, money, and resources on an application only to discover that someone else already holds the rights to a similar invention.
By following this step-by-step guide, you’ll learn how to:
• Identify existing inventions (prior art) that may overlap with your concept.
• Refine your invention to enhance its uniqueness.
• Avoid unnecessary application costs or rejection.
But why is a patentability search so important?
Imagine spending months perfecting your invention, only to find out it’s already patented. A patentability search could save you from this heartbreak and here’s how to do it right. A patentability search helps you
- Uncover prior art: This includes existing patents and public knowledge, helping you see what’s already claimed.
- Strengthen your application: Understanding competitors’ patents allows you to refine your claims and emphasize uniqueness.
- Save time and money: A thorough search reduces rejection risks and avoids costly legal disputes.

Step-by-Step Guide to Conducting a Patentability Search
Conducting a patentability search might sound complex, but it can be straightforward if you follow a step-by-step approach.
Clearly Define Your Invention
Before beginning your search, it’s important to have a clear understanding of your invention. Document what your invention does, its purpose, and any unique features it possesses. Clearly define the problem your invention solves and its essential features.
Choose the Right Keywords
Choose keywords that reflect your invention’s purpose and break down its key features using both general and technical terms.
Choose a Patent Database
Pick a database to start your search. There are many free and paid databases.
Free Patent Databases
- USPTO (United States Patent and Trademark Office): U.S. patents and applications.
- Google Patents: Global patent search across multiple countries.
- EPO (European Patent Office) Espacenet: European and international patents.
- WIPO PATENTSCOPE: International patents under the Patent Cooperation Treaty (PCT).
Paid Patent Databases
- Derwent Innovation (Clarivate): Professional-level patent search with analytics.
- Questel Orbit: Advanced patent search and legal status data.
- PatSnap: Patent search with business and patent analytics.
- LexisNexis TotalPatent One: a robust patent database that offers access to global patent information with powerful search and analysis tools.
- Patscout: Patscout is a patent search and analysis tool designed for businesses and IP law firms.
- Minesoft PatBase: This is an extensive patent database offered by Minesoft, with global patent coverage and advanced search capabilities.
Free databases can be sufficient for initial/Preliminary searches. If you require a more in-depth analysis, consider hiring a professional or utilizing paid databases.
Search for Existing Patents Using Your Keywords
After an initial search, you may find either too many results or very few. If you have too many results, try narrowing it down by adding more specific keywords or using filters. If you’re finding too few, try broader or related terms. Try different phrases and combinations of keywords to find better results. This experimentation can help you discover what works best for your needs.
Review Your Search Results
When you find a patent that appears similar to your invention, take the time to study it thoroughly. Start by reading the abstract and key sections, such as the detailed description and claims. The claims are especially crucial because they define the scope of the patent. Assess whether any claims overlap with the unique aspects of your invention.
Search with Non-Patent Literature
Not every great idea ends up in a patent office. Many valuable innovations are publicly available, just not patented. That’s why expanding your search beyond traditional patent databases is a smart move.
Ask yourself: Have you looked beyond patents? Here’s where to start:
- Academic journals & technical papers
- Websites & blogs
- Google Scholar
- Technical forums & online communities
- Product listings & catalogues
Evaluate Your Findings
After reviewing patents and non-patent literature, consider how your invention is unique compared to other similar inventions. Ask yourself a few questions: Does my invention provide a new solution, or is it similar to an existing product, or are there any modifications I can make to make my invention more unique?
Document Your Search Results
Keep a record of the patents and publications you reviewed, including patent numbers, titles, and any notes you’ve made on similarities or differences. This documentation can be helpful if you decide to move forward with a patent application and need to reference prior art.
Decide Whether to Move Forward with Your Application
Once you’ve analyzed your findings, you’ll be ready to decide whether to file your patent application. If you’re unsure, consider consulting a patent attorney for expert guidance. If your invention appears unique based on your search, you might be ready to start drafting your application. If there are similar patents, you may still have options by refining your invention or highlighting its unique features.
