In Agile, you are supposed to ship product on a regular cadence. All features are added to a product backlog, divided into small projects that fit within a sprint, and then prioritized.

Step 3. Check the date when the patent was first filed, using the results of your search. The filing date is listed toward the top of the page on the left under the list of inventors and the patent application number.tep 4. Add 20 years to the application filing date if the application was filed on or after June 8, 1995, to calculate the normal expiration date for the patent. If the patent application was filed before June 8, 1995, the patent's term is 17 years after the grant date of the patent.
