NOTE RE: USPTO Forms available in Adobe's PDF format for viewing and printing. To use them you must install Adobe's free Acrobat reader on your computer.

NOTE: The USPTO cannot assist you with the installation and configuration of the Acrobat reader on your system and printer. When Adobe Acrobat reader is installed as a browser plug-in, it sometimes exhibits problems printing complex documents. If you experience such problems, (which may even cause your browser application to fail), use your browser's right mouse button to click on the form hyperlink, save the form file on your machine's hard disk, and open it locally in the Acrobat reader.

The free Adobe Acrobat reader plug-in does not permit you to save a partially-filled form for later use. In order to save a partially-filled Fillable PDF form for later use, you must purchase and install the full Adobe Acrobat 5 software application or an equivalent product that has form data saving and editing capability.

Acrobat 5.0 or later is required for all fillable forms.
