The original infographic on The Guardian — www.guardian.co.uk/technology/2010/oct/04/microsoft-motor... — was pretty difficult to read, so I arranged these two graphics based on the same data.
The sizes are weighted depending on how many lawsuits connections there were. For the graphic on the left, suing someone would increase the size, receiving a lawsuit would decrease the size; vice-versa for the graphic on the right. It's pretty interesting to see that Kodak is actually the largest aggressor, and Sharp & Motorola were the largest receivers.
(Note, I never claimed to be a brilliant infographic designer. I'm sure others can do better. This was just done quickly to better represent the landscape.)
