USPTO's full-page images are stored and delivered at full 300 dots per inch (d.p.i.) resolution in an image file format called "TIFF," using CCITT Group 4 compression. Unfortunately, due to the volume of the image data, available funding, and other technical considerations, USPTO cannot convert these images to a format more popular on the Web either permanently or by converting on-the-fly as they are delivered.

The Cooperative Patent Classification (CPC) effort is a joint partnership between the USPTO and the EPO where the Offices have agreed to harmonize their existing classification systems (ECLA and USPC, respectively) and migrate towards a common classification scheme. This is a strategic decision by both offices and is seen as an important step towards advancing harmonization efforts currently being undertaken through the IP5’s Common Hybrid Classification (CHC) project.The migration to CPC will be developed based in large part on the existing European Classification System (ECLA) and will be modified to ensure compliance with the International Patent Classification system (IPC) standards administered by the World Intellectual Property Organization (WIPO).
