1.now the nation’s top patent court appears completely ready to scale back on business-method patents,which have been controversial ever since they were first authorized 10 years ago

先分句子的结构，很明显是主系表结构，因为有appear，表现，出现，在他之前的就是主语，之后的就是宾语

2.Curbs on business-method claims would be a dramatic about-face,because it was the Federal Circuit itself that introduced such patents with its 1998 decision in the so-called State Street Bank case,approving a patent on a way of pooling mutual-fund assets

先断句： Curbs on business-method claims would be a dramatic about-face,

because it was the Federal Circuit itself that introduced such patents with its 1998 decision in the so-called State Street Bank case,approving a patent on a way of pooling mutual-fund assets

可以看到这段话分成了三个片段， sec1: it is … that …，强调句的句型
