Apple and Samsung are in the middle of a number of different court cases around the world, with each company accusing the other one of infringing on each others patents.
Samsung and Apple are engaged in a court case in California, and now it would appear that both companies have actually dropped the amount of patent claims against each other.
Apple has halved the number of patent claims against Samsung, whilst Samsung has dropped five of its twelve claims against Apple, this was apparently done after the judge in the case, Lucy Koh ordered the two companies to reduce their amount of claims as there were too many for the trial which will take place in July.
