Filter Results by Keyword
Once you've added keywords and can see where they appear, you can switch from highlighting to filtering. This narrows the universe that AI looks at to only patents that contain your terms. This is the second stage of focusing your search.
Turn on keyword filtering
In the keyword panel on the left, switch the keyword Highlight to Filter and then Update results.
Your results now only include patents that contain that term. The result count at the top shows you the number of publications (not families) that match your terms — the size of the universe you're searching in.
How multiple keywords work
Same color group (same line) = OR.
Keywords on the same line are joined with OR logic — results must contain at least one of the terms. Put synonyms together: "folding" and "collapsible" on the same line. This means a patent mentioning either word will match.
Different color groups (different lines) = AND.
Keywords on different lines are joined with AND logic — results must contain at least one term from each group.
Example: Adding "folding" and "collapsible" on the same line gets patents mentioning either term. Adding "rotor" on a new line narrows to only patents mentioning any one of the folding terms and rotor.
Choose which sections to search
By default, keyword filters check the entire patent: title, abstract, description, and claims. You can change this by using the checkboxes.
For example, uncheck Description to find patents that use your keyword specifically in the title, abstract, or claims. This is useful for quickly narrowing to the most likely pool of results.
Tip: Make some keywords highlight only while still filtering with others. Uncheck all boxes to keep a keyword in highlight-only mode even when other keywords are set to filter. This lets you combine filtered and highlighted keywords in the same view.
Exclude keywords
You can also exclude specific terms. Add a keyword and set it to Exclude mode — this removes any patent containing that term from your results. This is not recommended in most cases. Often telling the AI what you want to find is more effective than excluding keywords. However, there are cases where exclusion is genuinely useful for filtering out noise. For example, removing tobacco from a search about a particular kind of plant-processing technique.

Switch back to highlighting
Switch any keyword back to Highlight Only and click Update Results to expand the search universe again. Your keyword will still highlight matches — it just won't exclude non-matching patents. This lets Amplified's AI tools look more broadly to identify relevant hits that didn't match your keywords.
