There is a thread pple is admitting guilt by implementing a design change due to the suit by VHC.
From a legal standpoint this is by no means an admission of guilt and would not be considered as such. The reason is that it would interefere with the development of important design changes and discourage innovation and development.
In any event, if it is implemented there are three logical outcomes:
1) It works and VHC is screwed
2) It doesn't work
3) It's still infringement and VHC jumps all over them
