According to PatentlyApple, which found the patents, the first patent was originally filed for in 2004 and covers a method for using a capacitive surface to make a multitouch display.

The patent application was amended to include 21 claims, including: 1) calculating the coordinates of each touch region comprises calculating a centroid of each touch region with the raw data associated with each touch region; 2) the processor calculates the boundaries using a watershed algorithm; and, 3) reducing the noise in raw data.

Whether or not the technologies covered by the patent were ever, let alone still are, used in Apple’s iOS devices remains to be seen. Whether or not any of Apple’s competitors are infringing on the patent also remains to be seen.
