The International Trade Commission (ITC) has made a preliminary ruling (PDF) that Apple has infringed upon two of four patent claims against the company made by S3 Graphics. The initial ruling made by an administrative law judge will go before a six-member commission, which will deliver its final verdict in November. S3 Graphics first filed its current patent suit with the ITC in June last year, claiming that Apple copied its graphics texture compression technology in its Mac and iOS product lines.
