First, SunnComm had two patent applications assigned to it (one abandoned), and two others with the same inventors (Eric Vanderwater and Peter Jacobs, both of the Phoenix area) unassigned:
US 2004-0103115 - 10/304,259
US 2004-0103044 - 10/412,453
US 2005-0278256 - 10/868,576
Final rejection mailed 10/24/05
US 2005-0177516 - 10/773,686
Non-final office action mailed 6/15/05
(which means that it is abandoned but can be revived).
First 4 Internet, LTD had two published applications assigned to it:
The US 2005-0223240 A1 application appears to be a US prosecution of an WO 2004-109681 A3 / GB 2402802 A European Patent Office (EPO) application.
Note that I haven’t had a chance to read these patent applications, nor have I looked to see if either of the two SunnComm inventors had other patents or patent applications.
