There’s no shortage of interesting lawsuits out there. But which ones are going to have the biggest impact? To find out, we talked to litigators across a wide range of practice areas. They pointed us to the cases that they’ve been watching most closely.

Women who used the NuvaRing contraceptive device have filed suit against its manufacturer. An American billionaire is seeking arbitration against the Hungarian government for a cancelled casino project. Two Silicon Valley giants are fighting over the patents for the Android smart phone. A group of banks have sued a insurer for spinning off its good assets into a separate company. And a challenge by 26 states to the new health care reform law seems to be heading to a showdown at the Supreme Court.
