The Supreme Court has taken on another possibly landscape-changing patent case that will determine if patent holders are able to sue everyone up and down the food chain for a patent infringement. "This case, officially between LG and Quanta, really concerns the question of how many times patent holders can get a cut of any component found violating a patent. Currently, patent holders will often sue up and down the food chain. So, if you happen to have a patent on a component within a motor that is used in automobile wipers, you could sue the motor maker, the wiper maker and the auto manufacturer -- and get all three to pay, even though the same product is used throughout the supply chain. This case will look at whether or not it makes sense to allow for that type of double, triple or quadruple dipping."
