WARF sued Apple for patent infringement on microprocessor technology patent for $400M.

The patent protected claims regarding processor chip design that improved microprocessor performance. WARF claimed that this patent was infringed upon by Apple's A7 processors for its iphone 5s and ipad.

A jury in Madison found that Apple did indeed infringe upon the patent, determining that it must pay WARF.

WARF argued that it is entitled to $2.74 for each device. WARF claims to be innovative and holds many patents, receiving $128 million from patent lawsuits from 2012-2014 alone. Since WARF does not produce products, can WARF be considered as a patent troll?
