IV’s Chief Litigation Counsel
Melissa Finocchio provided the following statement:
“We have been in active licensing
negotiations with Toshiba for many months, but are unable to reach mutually
agreeable terms. As a result, we’ve filed a complaint for infringement that
puts us on a course to end Toshiba’s unlicensed use of our intellectual
property.
Most of the world’s largest memory
manufacturers have recognized the value of our memory assets and are licensed
to our portfolio, yet Toshiba refuses to take a license and continues to use
our intellectual property in its products. Since business negotiations with
Toshiba have not been fruitful, we must take the necessary actions to protect
the interests of our inventors, investors and licensees.”
