Waze is an Israeli company that developed an Application (App) for helping drivers choose optimal routes and for estimating arrival times. It uses crowd sourcing to detect and help avoid congestion. Google bought Waze in $1.15 billion back in 2013.
Now another Israeli company, Makor Issues And Rights Ltd, is asserting two patents against Google: US 6,480,783 and US 6,615,130 both by David Myr.
Makor Issues And Rights Ltd have filed a patent infringement suit in the Federal Court of Delaware. They claim that Google Maps directly infringes the patents.
