Keyword filters

Filter and highlight basics

Keyword filters are used to focus on the particular features that you are interested in. When you add keyword filters, you will only see results that include those keywords and Amplified will also highlight those keywords. You can also exclude keywords.

´╣ŚNote: Amplified's keyword filters use automatic stemming so when you write "meter" we will include meter, meters, metered, metering, etc. without you needing to write each one out or use a wildcard

  • Highlights are visible both in your results list and on the full text patent pages in your project
  •  A colored icon at the right of the result will show you the number of exact matching highlights

    ­čôŁ Example: What happens if you add "meter" and a patent does not contain "meter" but includes "metered"? The patent will be included in your filtered results because of auto-stemming. However, the icon will say 0 because no exact matches were found.
  • Pressing Comma, Enter, or Tab will create your filter. You can add another after it.
  • Each filter can be a single keyword, an entire phrase, or even include more complex logic like a proximity operator (more on that below).

Customize filters by field

You can customize which section of the patent to filter against or turn filters off entirely to only highlight.

  • To only filter results with keywords in the claims, uncheck the Title, Abstract, and Description boxes but leave Claims checked
  • Choose "highlight only" from the ... menu to turn off all filter

Multi-highlight and boolean logic

Add one or multiple keywords or phrases by typing them into the first keyword color group and then hitting Comma, Enter, or Tab to finish one and make another. We recommend organizing similar concepts and synonyms together in the same color.

  • In the example below 'apple', 'orange', and 'grape' are all highlighted in green. Since these are similar concepts, it's helpful to see them in the same color and Amplified automatically joins them using OR logic when filtering.
  • Let's add 'juice' now. Since it is a different concept, we'll add it to the blue group. Now juice is highlighted in blue and joined with the green keywords using AND logic.
  • Click the x to remove entire keyword groups all at once or reset your keyword filters entirely by going to ... menu and select Remove all


Amplified's keyword filters support single and multi-character wildcards.

´╣ŚNote: Wildcards can not be used with keyword phrases. For example "aug*" and "aug*","reality" will work but "aug* reality" will not.

  • Use * to represent an unlimited number of characters. You must enter at least three characters before a wildcard (i.e. abc* not ab*)
  • Use ? to represent a single wildcard character
  • You can use multiple ? to represent a fixed number of wildcard characters such as h???o or he???

Proximity filters

You can use a proximity operator in a keyword filter to limit your results to specific keywords that show up near each other. For example, "electric vehicle" may be too specific but "electric" and "vehicle" is too vague. In this example you can solve this problem with a proximity filter to look for results that have "electric" near "vehicle".

  • To only show results that include removable within 2 words of doser, write an uppercase W2 separated by spaces in between the two keywords you want to search
  • The number you write after the W is the number of words. You can search within 1 to 9 words. For example, W9 will look within 9 words. The order does not matter.
