Similarity Search helps you quickly find applications that match what you're looking for. It offers two options — Semantic and Keyword — plus a Search Scope control to focus each search. Use the filter chips along the top row to refine your results.
Which search type should I use?
Which option to use depends on whether you know the exact terms you're after or you're looking for conceptually related applications.
Keyword search – Best when you know the exact terms that matter. Use it for specific jargon, chemical names, or technical phrases. Example:
"lithium iron phosphate" AND "cathode"Semantic search – Best when you want conceptually related applications, even if they use different words. Paste a claim or description, and Similarity Search surfaces matches by meaning. Example: a claim about cardiac monitoring surfaces ECG patches, heart-rate sensors, and arrhythmia detectors.
What is Search Scope?
Before you run a search, set the Search Scope to control which parts of an application Juristat searches across. Narrow it to specific sections for more precise results, or choose All Documents to search everything.
Using keyword search
Keyword search is ideal when you know the exact terms that matter. For example, you can use it to:
Identify applications that will likely receive Alice rejections,
Keep track of applications in emerging technology areas, or
Find applications taking advantage of the AFCP or Track 1 programs.
Keyword results display in a clean, easy-to-scan layout. Check out Advanced Search with Operators to learn how to get the most out of it.
Juristat Tip: Stay up to date on emerging tech by saving your searches. For example, search for "large language model" OR "retrieval-augmented generation", then save it to re-run at any time.
Complex search example: rejection searching
Searching 35 U.S.C. 102 Makato returns applications where both "35 USC 102" and "Makato" appear. To focus this on rejection text, set your Search Scope to the relevant sections before searching.
Using the same search but changing "102" to "101" and "Makato" to "Alice" helps identify applications that received Alice rejections.
Document code searches
You can often find applications of a specific type by searching a USPTO document code as a search term.
For example, search the document code A.NE.AFCP to identify applications using the AFCP program, or TRACK1.GRANT to identify Track 1 applications.
