NPR recently ran a full story on Intellectual Ventures and patent trolling. Most software patents are pretty ridiculous, and clearly the system needs some fixing. More on that in the future...
At the same time Crawford's patent was being prosecuted, more than 5,000 other patents were issued for "the same thing," Martin says.
Crawford's patent was for "an online backup system." Another patent from the same time was for "efficiently backing up files using multiple computer systems." Yet another was for "mirroring data in a remote data storage system."
And then there were three different patents with three different patent numbers but that all had the same title: "System and method for backing up computer files over a wide area computer network."
Martin says about 30 percent of U.S. patents are essentially on things that have already been invented. In 2000, for example, the patent office granted a patent on making toast — patent number 6080436, "Bread Refreshing Method."
