If you are an inventor, one of the very first questions you will face is whether your idea is new. The way to answer that is through a DIY patent search—a review of existing patents and publications (called “prior art”) that might be similar to your invention. A DIY patent search (do it yourself) is exactly what it sounds like; you perform your own search and review of the prior art found.
Here is the part many inventors underestimate: the effectiveness of your search depends heavily on the keywords you choose. That is why we created a free Patent Search Keyword Brainstorm Template to help inventors get started.
Use the wrong or too-narrow keywords, and you risk missing prior art that could block your patent. Use the right mix of terms, and you will uncover a clearer picture of the competitive landscape. That is why brainstorming patent search keywords is so important.
This guide will show you practical DIY patent search tips for keyword brainstorming, plus explain the limits of doing it yourself. Then, we will cover why a flat-fee patent attorney-led prior art search offers inventors the reliable, professional insight needed before filing.
Why Patent Search Keywords Are Crucial
When you type a search query into the USPTO database, Google Patents, or other search tools, the software does not “know” your invention the way you do. It is matching the words you use to the words others used in their patents. If you miss an important synonym or related term, you might overlook a relevant patent altogether.
For example, say you are working on a wireless headset. If you only search “wireless headset,” you might miss prior art that uses terms like “cordless earphones,” “Bluetooth audio device,” or “radio-frequency headset.” Each of those phrases could appear in a patent that matters for your invention.
That is why inventors need to brainstorm patent search keywords systematically. The broader and more strategic your keyword list, the more accurate your results will be.
A Step-by-Step Framework for Brainstorming Keywords
Here is a framework you can use to generate an effective set of search keywords for your DIY patent search.
1. Start with Your Invention’s Core Functions – Think about what your invention does, not just what it is called.
- Example: A “foldable chair” also performs the function of “collapsing” or being “portable seating.”
- Keywords such as “collapsible seat,” “portable chair,” and “camping stool” should be included in the search.
2. Use Synonyms and Variants – Every field of technology has multiple ways to describe the same thing.
- Example: A “wireless device” may also be described as “cordless,” “radio-frequency,” or “Bluetooth.”
- Create a list of synonyms for each component of your invention.
3. Think About Applications and Industries – How could your invention be used in different contexts?
- A biomedical device might be described in surgical, diagnostic, or therapeutic terms.
- A mechanical invention may also appear in automotive, industrial, or consumer applications.
4. Break Down Components and Features – List the individual parts of your invention. Each component can yield its own keyword set.
- Example: For a “solar-powered water purifier,” break it down into “solar panel,” “UV sterilizer,” “filtration system,” etc.
5. Include Broad and Narrow Terms – Balance your list with both broad concepts and very specific features.
- Broad: “fastener”
- Narrow: “spring-loaded clip”
- This ensures you don’t miss patents that describe your invention in general or highly detailed terms.
To make this easier, we have put together a printable Patent Search Keyword Brainstorm Template you can download and use for your own invention when conducting a DIY patent search.
Pro Tip: Create a spreadsheet and organize your brainstorm into columns (functions, synonyms, applications, components, broad terms, narrow terms). This becomes your Patent Search Keyword Brainstorm Template—a simple tool you can reuse for future ideas.

DIY Patent Search: Pros and Cons
Many inventors start with a DIY patent search, and there is real value in doing so.
Pros
- Low cost: It is free to search using the USPTO database or Google Patents.
- Educational: You will learn how patents are written and what kinds of inventions are already out there.
- Empowering: It helps you describe your own invention more clearly.
Cons
- Missed results: Without experience, it is easy to miss prior art because you do not know all the relevant keywords or classifications.
- False confidence: Finding “nothing similar” does not always mean your invention is patentable—it may mean your search was incomplete.
- No legal analysis: Even if you find prior art, interpreting whether it blocks your patent requires professional training.
DIY patent searching is a good starting point, but it is not enough if you are serious about protecting your invention. Even if you are doing a preliminary DIY patent search, our keyword brainstorming template resource page will show you how to expand your keyword list.
