If you have multiple copies of an NPL reference, you can remove the duplicates and make sure that all matters using this reference point to the remaining version. This can be done for all references or for one or more references at a time. You can also merge references.
Remove Duplicate References
- Hover over the Prior Art module and select All References.
- Check the references for which you wish to remove duplicates, or if you wish to remove duplicates for all references, you may want to change the items per page to 1000 and complete the following steps for each page.
- Click the Remove Duplicate References button.

AppColl will go through each and every reference if all boxes unchecked, or through the checked references, and look for exact spellings. Duplicates will be removed and any links between a matter and the now deleted duplicate reference will be updated to point to the remaining version. Files attached to the duplicates will not be deleted. But rather they will be carried over to the remaining version.
Merge References
- Hover over the Prior Art module and select All References.
- Select two or more references you wish to merge.
- Click the Merge References button.

- Select the desired reference(s) to replace all others.
- Clicking Merge will switch the links from the duplicate references to the selected reference and delete all of the duplicate references. Files attached to the duplicates will not be deleted, but will be carried over to the remaining version.
- If you wish to merge but not delete all of the duplicate references click the Merge (don't delete) option.
