NEW YORK- US patent officials on Thursday invalidated a third patent covering Israel's Teva Pharmaceutical Industries' $4 billion multiple sclerosis treatment Copaxone, after canceling two other patents on the drug last week.The ruling came in a challenge at the US Patent and Trademark Office by Mylan NV, which is trying to bring out a generic version of the 40-milligram injectable drug, taken three times a week. According to the US Food and Drug Administration, Copaxone is protected by five patents in total.Four airstrikes target Saada, Yemen - report
