- Text for each claim. Clicking the +/- on claim expands/collapses and dependent claim text.
- Clicking claims text also highlights the claim in the tree.
The + and – signs or the mouse scrollwheel may be used to zoom the claims tree in and out; clicking RESET restores the default view.
The two panels can be resized with a slider.

Note: You may view claims information in the new tab with/without the session open.

Compare Claims

If there is more than one document available in the domestic family or more than one document in the family has claims, there is a Compare With button. Clicking the button opens a dropdown menu listing the publication numbers available for comparison with the currently displayed document.

Selecting a publication number displays its claims tree in the right-side panel.

Clicking the Graph/Text toggle displays the claim trees or claim text for both documents. In either view, clicking a claim in one panel highlights it in the other.
