Our trademark attorney flat fee for Trademark Trial and Appeal Board (TTAB) filings. A trademark attorney with The Kinder Law Group will research the issues and prepare and file a Trademark Opposition (for pending applications) or a Trademark Cancellation (for issued registrations). Once you have filed the opposition or cancellation, you must then prosecute through to conclusion. We charge a rate of $350 per hour, so the costs can vary widely depending upon the nature of the case, the extent of defense by the third party, etc. We will provide budget estimates at various stages as the case progresses. In addition to the flat fee, the U.S. Patent and Trademark Office charges a $400 filing fee per property challenged. Send us an email below to get started.
