(For a longer list, see the wiki page List of lawsuits)

This page presents two lists: headline-making settlements over software patents, and lawsuits initiated over software patents. There are two points to note regarding these lists:

  • No patent lawsuit requires proving that the defendant copied the work of the plaintiff, and in almost all of the cases here, there is no evidence that direct copying of any kind occurred.
  • There is no comprehensive list of suits or settlements. For every suit here, there are countless others.
