Abstract
A computerized document storage system for use by inventors to store their work on an invention and to secure their claim to a date of invention, the system comprising a document creator to enable the inventor to describe his invention in a document, a document saver that stores the document with a digital signature of the inventor and a time stamp. The saver prevents any further modification of the document except an addition of: a witness statement, a digital signature, and a time stamp. The system also includes a witness document modifier that only allows the witness statement, the digital signature and the time stamp to be added to a stored document. A document viewer is also included to list the documents stored in the system and to allow the documents to be read.
