How to Conduct a Patentability Search – A Step-by-step guide for start-ups and inventors
A patentability search reviews patents and public disclosures to see whether an invention appears new. It helps identify prior art, reduce filing risk, and decide whether pursuing a patent application is worthwhile.
If you have developed a new invention, one of the first questions you should ask is simple:
What if a similar idea already exists and you just have not found it yet?
That is why learning how to conduct a patentability search is such an important step before filing a patent application. A patentability search helps you review existing patents, published patent applications, and other public information to determine whether your invention appears to be genuinely novel.
Without a proper search, you could spend valuable time, money, and effort preparing a patent application, only to discover that similar prior art already exists.
A well-planned patentability search can help you:
- identify prior art that may overlap with your invention
- refine your concept before filing
- reduce avoidable filing costs and rejection risk
- make a more informed decision about whether to move forward
If you are an inventor, startup, SMB, business, or innovator trying to protect a new idea, this guide will walk you through the process step by step.

Why Is a Patentability Search Important?
Imagine spending months refining your invention, developing a prototype, and preparing to file, only to later discover that a similar invention has already been disclosed.
That is the risk a patentability search helps reduce.
A patentability search is important because it can help you:
Uncover Prior Art
Prior art includes existing patents, published applications, technical publications, product disclosures, articles, and other public information that may relate to your invention.
Improve Your Filing Strategy
By reviewing similar inventions, you can better understand what makes your concept different and which features may deserve stronger emphasis in a future patent application.
Save Time and Money
A search cannot guarantee that a patent will be granted, but it can help you avoid moving forward blindly and reduce the risk of wasting resources on a weak filing strategy.
Make Better Business Decisions
For startups and businesses, a patentability search is not only a legal step. It is also a strategic decision-making tool that helps you evaluate whether an invention is worth pursuing, refining, or repositioning.
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
Begin by clearly outlining what your invention does, what problem it solves, and which features make it distinct. A well-defined invention makes it easier to search effectively and identify relevant prior art.
Choose the Right Keywords
Use keywords that reflect your invention’s purpose, structure, function, and technical features. Include both broad and specific terms, along with synonyms and related phrases, to improve search accuracy.
Choose a Patent Database
Start with reliable patent databases such as USPTO, Google Patents, EPO Espacenet, and WIPO PATENTSCOPE. If you need deeper analysis, paid tools like Derwent Innovation, Questel Orbit, PatSnap, LexisNexis TotalPatent One, PatScout, and Minesoft PatBase can also be useful.
Search for Existing Patents Using Your Keywords
Run searches using different keyword combinations. If the results are too broad, narrow them with more specific terms or filters. If they are too limited, try broader wording or related terms to uncover more relevant references.
Review Your Search Results
When you find a potentially relevant patent, review it closely. Focus on the abstract, detailed description, drawings, and especially the claims, as the claims define the scope of protection and help you assess possible overlap with your invention.
Search Non-Patent Literature
A thorough search should also include non-patent literature such as academic journals, technical papers, websites, blogs, Google Scholar, online forums, product listings, and catalogues. This helps uncover public disclosures that may also affect patentability.
Evaluate Your Findings
Compare the references you find against your invention to determine whether your idea offers a new solution or meaningful distinction. This step can also help you identify refinements that may strengthen your invention before filing.
Document Your Search Results
Keep a clear record of the patents, publications, and other materials you review. Include patent numbers, titles, links, and notes on important similarities or differences so you can refer back to them later.
Decide Whether to Move Forward with Your Application
After reviewing your findings, decide whether your invention appears unique enough to move forward. If similar references exist, you may still have options to refine your invention or highlight the features that set it apart. If needed, professional guidance can help you assess the next step.
Can You Perform a Patentability Search on Your Own?
Yes, you can perform a preliminary patentability search on your own using free public databases and online resources.
For many inventors, this is a useful first step.
A self-directed search can help you:
- understand the existing landscape
- identify obvious overlaps
- become more familiar with relevant terminology
- prepare for deeper review
However, self-searching also has limitations.
Many relevant references are easy to miss because:
- similar inventions may be described using very different language
- broad databases can produce noisy results
- non-patent literature is often overlooked
- interpreting claims requires care
That is why many inventors and startups begin with a preliminary search, then seek professional help if the invention is commercially important or the results are difficult to interpret.
When to Get Professional Help With a Patentability Search
A preliminary self-directed search can be useful, but many relevant references are easy to miss because similar inventions are often described using different technical language, classifications, or non-patent literature.
A professional patentability search can help you:
- identify stronger prior art
- understand overlap more clearly
- assess possible risk before filing
- make a more informed patent decision
If your invention has commercial value, if the technology space is crowded, or if you want more confidence before filing, professional guidance can be a smart next step.
What You Receive From a Professional Patentability Search
A professional patentability search typically helps you:
- identify relevant prior art
- understand how similar inventions are described
- assess important similarities and differences
- decide whether to refine your invention or move forward with filing
The goal is not just to gather documents. The goal is to give you a clearer basis for deciding whether your invention is worth pursuing in the patent process.
