What do the arrows on the Patent Term History screen indicate?

The arrow(s) in the Patent Term History display the measuring period for both applicant's delays and administrative delays by the USPTO.

• The box in which the initial up-arrow is located signifies the starting point of the delay being measured.
• The box in which the number is located signifies the event which stops the measurement.
• The number represents the amount of days that either the applicant or the USPTO delayed in prosecution of the application.
• The column with the heading (PTO) days signifies that the delays in that column reflect administrative delays by the Office.
• The column APPL (Days) signifies delays that reduce the amount of PTA (patent term adjustment) awarded in the PTO (days) column.
