DO Patent will only charge you for analyzed pages in excess of free pages at the end of the month. During the month, you can accumulate a number of paid pages (actions) before your credit card will be charged. Every user has a limit to the number of analyzed pages that can be performed prior to the card on file being charged. You can see how close you are to your personal limit in the Available Credit section of the Billing tab. Once you have hit your limit for paid pages (actions), you will not be able to process additional pages without contacting our support team at support@deeporigin.com.
