What this section covers

This section covers appeal fees for patent trials, specifically focusing on the fees required when filing an appeal with the Patent Trial and Appeal Board.

Key obligations

The primary requirement is to pay a $540 fee upon filing an appeal from the examiner to the Patent Trial and Appeal Board.
Additional fees may be required beyond the initial filing fee, depending on specific circumstances.
