Oliver on Patent Trolls: Burying Innovation Under a Pile of Lawsuits

For inventors, patents are an essential protection against theft. But when patent trolls abuse the system by stockpiling patents and threatening lawsuits, businesses are forced to shell out tons of money to people only interested in making a buck off of other peoples hard work, and congress can not do anything under the weight of lobbyists for the lawyers who love these kind of frivolous and uncalled for litigation. Last Week Tonight with John Oliver takes on the Patent Trolls in this video from Sunday night.
