How can I access published international applications?

Published international applications are made available to the public through various means:

• WIPO’s PATENTSCOPE database: This is the primary source for accessing published PCT applications. It’s available at https://patentscope.wipo.int/.
• USPTO’s Patent Application Information Retrieval (PAIR) system: For applications that have entered the national phase in the US.
• Other national patent office databases: Many countries provide access to published PCT applications through their online patent databases.

MPEP 1857 states: “The International Bureau publishes a PCT pamphlet containing the international application on the international publication date.” This pamphlet is what becomes publicly accessible through these databases.
