I was recently sued for infringing patent. There were no warning emails, letters sent to me. Apparently, five other companies have been sued for the same. Looks like a patent troll. With the help of an attorney, I was able to reach out to the plaintiff to discuss a settlement. After months of going back and forth, not settlement was reached. The plaintiff demanded more than I could afford. With no settlement reached, the plaintiff has placed a joint discovery, which is due in 20 days. My attorney had advised me to take the technology out of my website, which I did. He also advised me hire the services of a patent company to research the claims, which I did. The results indicate that the patent is invalid. In reality, I do not want to fight this further due to the limited resources I have. A trial date has already been placed. My question is what I should expect moving forward? From the financial point of view, I might have not further option, but to represent self. How do I need to prepare for this case?
