New submitter Shavano writes with news that Apple's attempt to block Samsung from introducing evidence of a tablet prototype developed in 1994 has been denied by U.S. District Judge Lucy Koh. Part of the reason Apple got a sales ban on Samsung's Galaxy Tab 10.1 earlier this year was that an Appeals Court said Apple's tablet design was significantly different from earlier designs. Now, Judge Koh has decided that the issue needs to be decided by a jury.
