Earlier this month we reported that the US district court in Texas decreed that Samsung Display and Samsung Electronics are to pay $62.7 million in damages as the companies wilfully infringed upon two of Solas OLED fundamental OLED patents (USPTO #7,446,338 and #9,256,311).
Samsung proceeded to file a patent office challenge against the #311 patent, and apparantly Samsung won the challenge. The patent describes a flexible touch sensor that is wrapped around the edge of the display - and Samsung argued that as a flexible touch sensor is already known, this patent is "obvious". It appears as if Samsung will not have to pay the $35.4 million in damages for this patent.
We do not know whether Samsung also filed a challenge on the #338 patent (for which the damages were $27.3 million).
