began with a patent issued on July 13, 1836. Prior to that date, 9,957 patents had been issued. The user should note that the data in this table have been checked but that it may still not be completely devoid of errors. Numbers, as displayed in the table, are 7 characters with the numeric portion padded with leading zeroes where necessary. Note that some numbers within a series may be unused. Therefore, the number of patents granted during a year cannot be determined by simply subtracting the number of the first patent issued in one year from the number of the first patent issued in the next year. Reissue patents were not separately numbered until 1838 Defensive Publications and Improvement (AI) patents are not included in this table.

Important Notices Concerning These Databases from The United States Patent and Trademark Office These databases are intended for use by the general public. Due to limitations of equipment and bandwidth, they are not intended to be a source for bulk downloads of USPTO data. Bulk data may be purchased from USPTO at cost (see the USPTO Products and Services Catalog). Individuals, companies, IP addresses, or blocks of IP addresses who, in effect, deny service to the general public by generating unusually high numbers (1000 or more) of daily database accesses (searches, pages, or hits), whether generated manually or in an automated fashion, may be denied access to these servers without notice. If you can access this page, but cannot successfully access any of the Quick Search, Advanced Boolean Searching, or Patent Number Searching pages linked above, your workstation or organization may have been denied access to the Web Patent Databases. To determine if you have been denied access, or to seek to have your access restored, send email including your workstation and firewall or gateway IP addresses to larson@uspto.gov. Consult with your network administrators if necessary, as email without the required IP addresses cannot be processed. Users creating their own hyperlinks to pages on this site are requested and cautioned to do so in a manner which maintains a clear distinction between the user's content and official content published by USPTO. Users packaging pages from this Web site hyperlinked within frames are requested and cautioned to properly identify USPTO-provided content. Patents issued between 1790 and 1976 are searchable only by patent number and current US classifications. US Patent Classification data in the Full-Text Database (Current US Classification [CCL]) has been updated to reflect the most current Master Classification File, and may not match the classification data which appears on the patent full-page images (i.e., 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 USPTO are not reflected in the text or image portions of the patent databases. Sequence listings associated with about 95% of the biosequence patents published in 2001 only are not contained in the patent full-text database. The sequence listings do appear in the full-page images of the affected patents. PTO is presently investigating the feasibility of adding these sequence listings to the full text. In the full-page images, sequence listings usually appear at the end of the specification. One way of navigating to the sequence listings is to click on the [Claims] section navigational link, and then back up one page. If you have any questions about the patent application process, the USPTO strongly recommends that you consult with a registered patent attorney or agent. The USPTO cannot recommend attorneys or agents. For information on registered patent attorneys and agents, see Patent Attorneys and Agents Registered to Practice before the USPTO. Additional information about the patenting process is available elsewhere on the PTO 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 USPTO's patent database does not mean that the invention is patentable. The USPTO's text-searchable patent database begins with patents granted since 1976. A complete patentability search must consider all prior art, including earlier patents, foreign patents and non-patent literature. Please note that USPTO 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. USPTO does not plan to change this operational policy.
