NEW YORK (CNNMoney) -- Patent trolls -- companies that license patents
but do not actually sell anything -- have long been looked on with
fiery scorn in Silicon Valley. This week, a Boston University study
offered fresh fuel for those flames.
Lawsuits from non-practicing entities, or NPEs -- better known as
patent trolls -- have cost innovators $500 billion in lost wealth from
1990 through 2010, the BU study found. The study arrived at that
figure by observing patent defendants' stock prices following a
lawsuit, excluding general market trends and random stock movements.
Jeg håper flere forsker på patentsystemet fremover.
