I want to know the answer to the following question:
How many years did Bell and the US Government fight in court?
All the background I'm provided with is that "By the time that the trial wound its way through nine years of legal battles, the U.S. prosecuting attorney had died and the two Bell patents (No. 174,465 dated March 7, 1876 and No. 186,787 dated January 30, 1877) were no longer in effect, although the presiding judges agreed to continue the proceedings due to the case's importance as a "precedent".". Is that enough to answer the question?
Answer: no
