There are already four points that can invalidate the patent, described in the article, including prior art of another phone and an ACM Journal in 1992. Additionally, the patents are too general and cover almost any User Interface to unlock a phone. This is just another in a growing list of examples of how the US patent system is being abused, costing company budgets defending themselves from frivolous patents at the expense of innovation and technology growth."
