Custom fields can now be shared to other people with a PatSnap license.
This will enable you to allow other users to use the custom fields you have created on any Workspace that they have edit rights to.
To share the custom field, you will have to access the "My Custom Fields" area shown below.
From here, you can view all your custom fields, and if you move your mouse over you will see various options available to you.
Once you have clicked the share button, a pop-up prompt will appear to ask you who you wish to share it to.
Enter the email address of the user you wish to share it to, and click "Share".
