Patent 6012072 Issued on January 4, 2000. Estimated Expiration Date: January 5, 2016. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
An apparatus for displaying documents on a computer controlled display device provides a method for clipping. To clip a document is to restrict the viewable area of the screen object on the computer controlled display device associated with the document. A workspace viewer process maintains the documents in a three-dimensional virtual workspace. A document renderer and attribute-value pairs accomplish clipping in the virtual workspace. Clip stops constrain the clipping edges of a document so that the document may be clipped only to a specified set of positions.
