Canon vs IV Patent Arguments

Delaware Intellectual Property Litigation publishes a detailed document on trial where Intellectual Ventures accuses Canon in patent infringement, including two image sensor patents: US6,221,686 "Method of making a semiconductor image sensor" and US6,023,081 "Semiconductor image sensor." Canon has lost the battle, in spite of Eric Fossum and Albert Theuwissen trying to defend it, see pp. 11-19 in the document.
