Suppose you are working on stock market prediction. You would like to predict whether or not a certain company will win a patent infringement lawsuit (by training on data of companies that had to defend against similar lawsuits). Would you treat this as a classification or a regression problem?

Answer: I'm not following you. You mean like cheating while I'm doing my job (predict) ?

Explanation: Working in the stock market might be classified as "it's a dirty job, but someone has to do it", and it doesn't matter. There's no such thing as cheating or playing dirty. Earning your salary by predicting other people incomes an outcomes it's just as any other job, and the position or situation of those people, it's just a part of your job.
