This case was somewhat famous because of two defendants:
An interesting fact is that default was entered as to 5 defendants earlier, two of them were dismissed with prejudice later, defendant Young Lin was even dismissed twice: in Document 44 and Document 52. (Effectively Mr. Sperlein invented a new legal concept — double escape from jeopardy.)
So what about the remaining three? Seems that Mr. Sperlein completely lost interest in copyright trolling, otherwise I don’t think he would miss this chance to straighten his weapon of fear.
