US Patent
Classification data in the Full-Text Database (Issued US Classification) corresponds to classification
data which appears on the printed patent, and may not match current
classification data.
US Patent
Classification data in the Bibliographic Database (Current US Classification) has been updated to reflect the
most current Master Classification File (July 1, 1999), and may not match the classification
data which appears on the printed patent.
Changes to patent
documents contained in Certificates of Correction and
Re-examinations Certificates are not included in the text of the
patent databases, but are included as full-page images at the end of
each patent's linked image pages.
Assignment changes
recorded at the PTO are not reflected in the text or image portions
of either of the patent databases.
If you have any
questions about the patent application process, the PTO strongly
recommends that you consult with a registered patent attorney or
agent. The PTO cannot recommend attorneys or agents. For information
on registered patent attorneys and agents, see
Patent
Attorneys and Agents Registered to Practice before the
PTO.
Additional
information about the patenting process is available from
PTO's Web site and at
Patent and
Trademark Depository Libraries located throughout the
country.
The fact that an
invention cannot be found by searching in the PTO's patent databases
does not mean that the invention is patentable. Both of the PTO's
patent databases begin with patents granted since 1976. A complete
patentability search must consider all prior art, including earlier
patents, foreign patents and non-patent literature.
The
previously-offered AIDS Database has been discontinued, since it has
been rendered obsolete and redundant by the availability of
searchable patent full-text supplemented by full-page images. AIDS
researchers can now design their own customized searches tailored to
their specific needs and apply them to the full-text database.
Please note that PTO
does not record or log the parameters of search requests submitted
to these databases. Such uncollected information has thus never been
disclosed through sale or FOIA request, intentionally or otherwise,
to any third party. PTO does not plan to change this operational
policy.
