Did you have access to the code in order to develop your system?

If so, you will have a difficult time showing that your work is not a 
derivative of the earlier one. It is for this reason that the "clean 
room" <URL:> 
implementation approach is often taken. Did you take such an approach, 
and can you show evidence that this is the case?

This statement would seem to be the basis of what you're claiming. The 
issue would be whether you can show evidence that you implemented your 
work without infringing copyright in the earlier work.

Is copyright the only violation they are claiming? Ignore meaningless 
"intellectual property" claims and look for what specific law they 
claim you're violating.

Please fix your "From" field in the header of your messages, so that 
it shows your name.
