## Abstract

The United States Patent and Trademark Office (Office) is adjusting certain patent fee amounts for fiscal year 2009 to reflect fluctuations in the Consumer Price Index (CPI). The patent statute provides for the annual CPI adjustment of patent fees set by statute to recover the higher costs associated with doing business. In addition, the Office is correcting the addresses for maintenance fee payments and correspondence, and deposit account replenishments.
