What information about patent applications is publicly available?

Certain information about patent applications is publicly available, even if the full application is not. According to 37 CFR 1.14(a)(1)(ii) and (iii), for published applications, the following information may be communicated without a petition for access:

• Whether the application is pending, abandoned, or patented
• Whether the application has been published under 35 U.S.C. 122(b)
• The application “numerical identifier” (application number or serial number plus filing date)
• Whether another application claims the benefit of the application

For published applications, “A copy of the application-as-filed, the file contents of the application, or a specific document in the file of a pending published application may be provided to any person upon request and payment of the appropriate fee set forth in §1.19(b).”

However, for unpublished applications, this information is generally not available to the public unless the application is identified or relied upon in a patent document or other published application.
