The XenForo source code hasn't yet been released, so it would seem unlikely the lawsuit is based on code similarities. In any case XenForo have mentioned they have quite a different architecture to anything else.

Equally it is likely that a developer will not ignore prior learning. That's what they call experience.

A lawsuit like this will surely be won by the side with the most money (the side that can afford to keep going the longest). That is unlikely to be a small bunch who have been developing software for the last couple of years instead of making money.
