Industry Expert Analyzes Nomadix Patent
Patent number 6,636,894 has 11 claims. Of these, 2 are so-called ?independent claims?, and the other 9 depend on one of these two independent claims (or on another dependent claim.)
1. A method for redirecting an original destination address access request to a redirected destination address, the method comprising the steps of:
Receiving, at a gateway device, all original destination address access requests originating from a computer;
Determining, at the gateway device, which of the original destination address requests require redirection;
Storing the original destination address if redirection is required;
Modifying, at the gateway device, the original destination address access request and communicating the modified Request to a redirection server if redirection is required;
Responding, at the redirection server, to the modified request with a browser redirect message that reassigns the Modified request to an administrator-specified, redirected destination address;
Intercepting, at the gateway device, the browser redirect message and modifying it with the stored original destination address; and
Sending the modified browser redirect message to the computer, which automatically redirects the computer to the redirected destination address.
and
6. A system for redirecting an original destination address access request to a redirected destination address, the system comprising:
A computer that initiates original destination address requests;
A gateway device in communication with the computer, that receives the original destination address requests from the computer, determines if redirection of any of the original destination address requests is required, stores the original destination address request if redirection is required and modifies the original destination address request if redirection is required, and
A redirection server in communication with the gateway device that receives the modified request from the gateway device and responds with a browser redirect message that reassigns the request to an administrator-specified, redirect destination address, wherein the gateway device intercepts the browser redirect message and modifies the response with the stored original destination address before forwarding the browser redirect message to the computer and wherein the computer receives the modified browser redirect message and the computer is automatically redirected to the redirect destination address.
The article further goes on to list three possible methods to fight or work around this patent, if it was to go through.
