Claim Sleuth is a search engine that helps you identify possible restrictions on freedom-to-operate or possible infringements. It employs advanced artificial intelligence and indexing techniques to quickly and precisely search independent claims in all active US utility patents. It is regularly updated with newly granted patents as they are published.

In order to use Claim Sleuth, you must first obtain access for your organization via the request form. After obtaining access and logging in, you will be redirected to the web interface of Claim Sleuth. You can either download a randomly sampled claim or draft your own idea description for the testing purposes. It is important to clearly describe your idea and use punctuation to separate key aspects (as in the sample claims) for best matching performance.

Yes! You can narrow the search results by clicking the icon at the upper right corner of the input area to restrict assignee, class, title or claim text using regular expressions or a simple key word. You can broaden the search results to include less semantically similar statements by activating the broad switch.

Please see the demo for more detail.

Unlimited searches for up to 10 separate accounts within an organization is available for a monthly charge of $899. Please include any additional needs or concerns on the request form.

A query fragment is the basic input unit into which a submitted description is split for matching. It is important to encapsulate individual components of your idea into a query fragment for best results. Specifically, a description is split into query fragments using commas, colons, semicolons as boundaries then merging text between these boundaries as needed to ensure no query fragment has fewer than six informative terms. This approach has been observed to work well with most published independent claims, so it is advisable to mimic the composition of these for your own idea descriptions.
