@tsarstepan,
As I recall, there has been a tolling provision carved out, with reference to who can sue when, in copyright law. What that means is, the statute begins to run (much like we see with medical malpractice, BTW) when the infringement is
discovered, versus when the infringement occurred. I think once the Supreme Court is whole again, someone will push a case up to them to get them to weigh in.
