Once you get the original notice of the lawsuit, you get to file a response. From then, the originator can come back with a "discovery" process, requesting documents about your business and its financials, asking questions that may help them in suing you. In this case, once Cat & Cloud filed the response, they also asked for the same information from Caterpillar Inc. There's no end to how much information each one can request, meaning whoever has more money can keep draining the other side's time and finances. The process is stacked against the little guy.
