Patent 7228501 was granted and assigned to Microsoft on June, 2007 by the United States Patent and Trademark Office.
The invention is generally directed to a method for selecting a font that uses a mark-up language document to group together multiple pre-existing fonts into a single font family or “virtual font.” The mark-up language document includes rules regarding the conditions under which individual fonts within the family are to be used. This permits, for example, a font developer to create, in an efficient manner, an international font using several preexisting fonts.
