Prenda Law Inc. and the Southern California lawyer fighting its alleged copyright trolling spent the weekend arguing whether U.S. District Judge Otis Wright in Los Angeles overstepped by forcing Prenda to post a $237,000 appellate bond that would cover attorney fees on appeal.

Prenda returns to a familiar theme, arguing that Los Angeles attorney Morgan Pietz hasn't identified an actual client with standing to recover attorney fees under the Copyright Act. "John Doe, whoever he or she might be, and the truly interested appellee, Morgan Pietz, have [already] received sufficient security to insure the underlying, but unlawful sanctions issued by the District Court," Prenda's attorney, Heather Rosing, a shareholder and CFO at Klinedinst, wrote in a Monday filing.
