Notice of Expiration of Patents
                   Due to Failure to Pay Maintenance Fee for
                      March 29, 1998 through May 10, 1998
   
  
   35 U.S.C. 41 and 37 CFR 1.362(g) provide that if the required
maintenance fee and any applicable surcharge are not paid in a patent
requiring such payment, the patent will expire at the end of the 4th,
8th, or 12th anniversary of the grant of the patent depending upon the
first maintenance fee which was not paid.
   
   According to the records of the Office, the patents listed below have
expired due to failure to pay the required maintenance fees and any
applicable surcharges. The listing is unusually long because issues of
the Official Gazette published since June 2, 1998 did not properly list
patents which issued on or after March 29, 1994 that expired due to
failure to pay the 4th-year anniversary maintenance fees. The following
listing includes patents that issued on or after March 29, 1994 which
have expired due to failure to pay the 4th year maintenance fees, which
should have already been published in the Official Gazette.
   
   In addition, patents that issued on or after March 29, 1994 and which
expired due to failure to pay the required 4th-year anniversary
maintenance fees and any required surcharge may not have received a
Notice of Patent Expiration. Lastly, notices reminding patentees of the
requirement to pay amaintenance fees (Reminder Notices) have not been
mailed for many patents which issued on or after March 29, 1994. The
Office has resolved the computer problems that led to the failure to
properly list patents which expired in the Official Gazette and the
failure to mail the proper reminder and expiration notices. Notices of
Patent Expiration, which should have already been mailed for patents
which expired due to failure to pay the 4th year maintenance fee that
was due with a surcharge by March 29, 1998, will be mailed in these
patents. The Reminder Notices that should have been mailed, but because
of the problems that have now been resolved were not mailed, may also be
mailed if the patent has not expired.
   
   Patentees and other customers seeking information as to whether the
maintenance fee for a specific patent has been paid may obtain such
information by calling Maintenance Fee Division at (703) 308-5068 or
(703) 308-5069. Alternatively, requests for an uncertified statement
regarding the status of maintenance fee payments for a specific patent
may be faxed to Maintenance Fee Division at (703) 308-5077. Self service
computer terminals are also available to the public and provide
maintenance fee and assignment information for patents. These terminals
can be found in the Public Search Room (located on the lobby level,
between Crystal Plaza 2 and Crystal Plaza3), and the Patent Assignment
Search Room (Crystal Plaza 3-2C03).
