If the key element that you're upset about was telephone guided co-browsing, I call "not unique".
You may very well have been the ones to introduce the idea/term to Faberge, but if you were the first ones to pitch AJAX or Flash to them, should they be barred from using that in their eventual solution, too?
AJAX and Flash is a generic technology, telephone guided co-browsing is a specific implementation, most likely using that technology. There's a big difference there, especially when Flash and AJAX are ubiquitous on the web and the phone guided browsing is more innovative.
