IPIX ./ Dersch: German Mathematician silenced by US patent
[an error occurred while processing this directive]

A German developper of free software has been persecuted by the US company IPIX for writing software for composing pictures into large panoramas using calculation rules which he had developped independently but which iPIX had patented in the USA. In June 2001 the conflict escalated. Prof. Dersch withdrew his software from the Net in order to evade a lawsuit which iPIX was, according to his knowledge, preparing in the US.
