周五，智能手机巨头苹果公司(Apple Inc.)与三星电子(Samsung Electronics Co.)之间漫长的专利战将再次成为外界关注的焦点，届时做出的两项裁决可能会扭转形势。
The companies will argue before a federal appeals court in Washington over whether a lower court erred last year when it allowed Samsung to continue selling more than two dozen products after a jury found they infringed several Apple patents.
Also on Friday, the International Trade Commission, a quasi-judicial federal agency that can block imports of foreign-made goods, is expected to issue a ruling on whether Samsung infringed several different Apple patents. Samsung is based in South Korea, and Apple's iPhone's are manufactured abroad.
同样是在周五，预计美国国际贸易委员会(International Trade Commission)将就三星是否侵犯了苹果多项专利做出裁决。该联邦机构具有准司法机构性质，能够下令禁止外国产品的进口。三星总部位于韩国，苹果 iPhone则是在美国境外生产的。
Spokeswomen for Samsung and Apple each declined to comment.
The nearly $400 billion smartphone industry has been roiled by more than three years of expensive litigation among smartphone makers in courts all over the world. Still, a decisive winner has yet to emerge.
The events taking center stage on Friday could help clarify the strengths and weaknesses of the two leading sellers of smartphones. They follow the Obama administration's veto last Saturday of an ITC order banning the import and sale of some Apple iPhones and iPads.
Victories for Apple on Friday could keep some current and future Samsung smartphones from the marketplace and cut into the company's commanding lead in world-wide smartphone sales. Victories for Samsung likely would allow the company to keep selling the full complement of its mobile devices.
The appeals court case, in particular, could help determine whether Apple will be able to win product bans in future cases, including one case pending in San Jose, Calif., which is set to go to trial early next year.
The case being heard Friday by the U.S. Court of Appeals for the Federal Circuit, a specialized court that handles appeals of patent cases, arose from a earlier complaint that Apple filed against Samsung in federal court in San Jose in 2011, which went to trial last year.
美国联邦巡回上诉法院(U.S. Court of Appeals for the Federal Circuit)周五审理的案子因早些时候苹果起诉三星案而起。2011年，苹果在圣何塞的联邦法院起诉三星，该案去年进行了审理。
