Beginning Wednesday, May 13, the USPTO is going to start accepting International Design Applications, as an office of indirect filing on behalf of the International Office, i.e., the World Intellectual Property Office or WIPO.  Any new applications for designs from American companies or design inventors should be filed this way, rather than directly to WIPO, because of the requirement for a security review in the US.  This system permits you to file up to a hundred designs at one time, and the drawings can be either photographs or black-and-white drawings.  The USPTO has just released its EFS-Web Quick Start Guide with instructions about how to file a Hague application on-line in the US, and the QSG can be downloaded here.
