请高手帮我分析下句子成分

Question

...，because it was the federal circuit itself that introduced such patents with is 1998 decision in the so-called state Street Bank case,...

Answer 1

因为正是联邦巡回法庭自己在美国道富银行案中用“1998决定”引入了这些专利追问

谢谢您详尽的翻译，如果可以的话，能不能帮我分析一下句子的语法结构？

追答

（it was ）the federal circuit itself（ that ）introduced such patents with its 1998 decision
it is...that...是强调句型 为了强调the federal circuit itself巡回法庭自己。
强调句的特点是：去掉了 it is和that，句子仍然是个句子（有独立的主谓宾）。
with is 1998 decision 做方式状语
