Its Samsung turn to present their evidence in their ongoing trial with Samsung and the evidence presented yesterday surrounds Apples “Pinch To Zoom” patent. Samsung believes they have found evidence of prior art in a Mitsubishi built system called “DiamondTouch” which utilised a similar system. Whilst the video doesn’t show something as functional or as polished as what Apple eventually launched there are a few similarities. Samsung has spent a lot of time looking for prior art to counter-act Apples claims and this one comes with the added extra that Apple allegedly met with Mitsubishi and were shown this implementation in 2003. It is interesting that Samsungs defence seems to be more focused on disproving Apples patents rather than showing they didn’t copy them but this is early in Samsung testimony and there are sure to be many more revelations to come before the case ends in a few weeks.
