PatentID

USPTO IDs are generated in the following way

Patents

• Applications: application number: 4-digit year (starting in 2001) followed by 7 digits

Applications

A Publication number includes a four-digit year, followed by a seven-digit sequence code followed by a two-character Kind Code that is assigned by the USPTO. The system displays the publication number with or without the "US" prefix and the Kind Code suffix (e.g., US YYYY-9999999 A9 or 9999-9999999). https://www.uspto.gov/patents/apply/applying-online/publication-number

• Re-examination utility patent number: B followed by up to 4 digits (issued before 01/02/2001)

Trademarks

• Trademark application serial number: 8 digits
• Trademark reel and frame number: 4-digit reel followed by 4-digit frame
