Apple disagrees. "They suggest that they have a lesser solution, but that is simply not true," said Apple's lawyer Theo Blomme to judge Peter Blok, who presided over a team of three judges, in a response to Samsung's claim. The technique used in Android does solve a multiple input "conflict situation" and in that way the Android software essentially does the same as Apple's, he said.

It is also possible to assign exclusivity to one particular "view" in Android, and thus Samsung infringes on the patent, said Rutger Kleemans, Apple's other lawyer in the courtroom.

Both Samsung's and Apple's legal teams concentrated on how to interpret the specific wording in the patent document.

Samsung also claimed that Apple's touch event model patent is invalid because it is very similar to other technology and thus not a new invention. DiamondTouch, software that allows multiple users to interact with a touch-based tabletop interface simultaneously, is an example of so-called "prior art," said Samsung lawyer Mattie de Koning. DiamondTouch and is able to recognize which person touches the surface at a certain place and is also able to recognize whether one user uses two hands for multitouch input, De Koning said, adding that this is similar to Apple's patent. DiamondTouch was developed by Mitsubishi Electric Research Labs and later licensed to Circle Twelve.

Apple dismissed this claim by stating that DiamondTouch cannot be compared to its technology because it is meant for multiple users, and not just for one.
