This section contains the text and drawings of U.S. patent number 6,757,699.
Much of what follows was written prior to October 2000; the final form of patent application number 09/849,716
was submitted to the United States Patent and Trademark Office in May 2001.
The application with its claims was "allowed"
on April 19, 2004. Patent number 6,757,699 was issued June 29, 2004.
The abstract provides a quick overview of the "method and system for fragmenting
and reconstituting data".
The background of the invention describes the current situation in the
field of providing confidentiality for computer files, and suggests why the current invention provides
an improvement.
Buried in the turgid legalese of the "summary of the invention"
you will find
a list of objectives to which the Pryvit technique is directed.
After a two paragraph preamble, the "brief description of drawings" is made up of
31 very short paragraphs, one for each of the 31 drawings. Figure 32 is spread in full.
The "preferred embodiment" is long! It is, if you like, an anything-but-brief
description of each of the 31 drawings. As in all patents, it is written in sufficient detail so that a "person of
equivalent art" could create a work based on this technology.
The claims are pure legalese, intended to discourage the morally challenged
from distributing "design-around" products without paying royalties. Firms that care about their reputations know
not to even try.
The Patent section of this site is extensive. You can read it sequentially
using the "Prev" and "Next" buttons near the top and bottom of each page. Alternatively, you may find the
Proximity Search tool useful.
