Erratum

   The United States Patent and Trademark Office (USPTO) published
a final rule entitled "Changes to the Time Period for Making Any
Necessary Deposit of Biological Material" in the Federal Register on
April 27, 2001 (see 66 Fed. Reg. 21090 (Apr. 27, 2001)), and republished
that final rule in the Official Gazette on May 22, 2001 (see 1246 Off.
Gaz. Pat. Office 104 (May 22, 2001)). The final rule as republished in
the Official Gazette erroneously indicates that its changes to the rules
of practice apply to any application in which a Notice of Allowability is
mailed on or after June 21, 2001. The final rule as published in the
Federal Register on April 27, 2001 correctly indicates that its changes to
the rules of practice are effective on May 29, 2001, and are effective for
any application in which a Notice of Allowability is mailed on or after
May 29, 2001.

   Therefore, the final rule as republished in the Official Gazette on
May 22, 2001 is hereby corrected to indicate that its changes to the rules
of practice are effective on May 29, 2001, and are effective for any
application in which a Notice of Allowability is mailed on or after
May 29, 2001.
