Absolutely! I cannot speak for other companies/defendants, but in our case our aim is to make it very cost effective to invalidate patents that may later be used to sue your company.
Most fees in litigation and patent invalidation go to lawyers. We chose a kind of patent reexamination that can be automated, and we're working on the process. We have automated a great chunk of the process and paperwork already. That will bring costs down and democratize patent invalidation.
