Brandwine Suing ADSL ISP's

ATT, Verizon and CenturyLink embroiled in ADSL patent fight with Brandywine Communications Technologies, a patent holding company.

To date, Brandywine has sued over 39 different service providers, according to Fierce, but another source says "There are 52 involved ISPs, the initial four large folks from earlier this year, and then 48 new ones last week."

"In addition to filing a lawsuit against ATT, Verizon and C-Link last year, the company has sued Windstream, IKANO, and Megapath. It is also currently trying to settle one of its cases with EarthLink."

I have listed some below but there is a list here as well.

From a complaint: "On April 27, 1993, U.S. Patent No. 5,206,854 (the "'854 Patent"), entitled "Detecting Loss of Echo Cancellation" was duly and legally issued by the United States Patent and Trademark Office to inventors William L.

We need Patent Reform in the US - Big Time. As I told the USPTO, your department is screwed up. For example, how do you give out a patent in 2011 for technology in use since 1999 AND technology that Bell Labs developed in 1965!!!
