Tag patents right in your folder or sub-folder. Select the patents you want to tag and click on the Tag icon from the toolbar. You can choose from the default labels: Risk and Relevance, and select the type or ranking, say, either High, Medium, or Low.
By clicking on the Edit button, you can customize your labels by editing the label dialog box. You can create a new label, give it a subject (used for comparison, which may include products, technology, patents, etc.), a label name, and a range.
You can also view the tagged patent/s in your Tagged folder.
