The now-disbanded Niro, Haller & Niro made a name for itself through aggressive patent litigation against big technology companies. But it also suffered at least one black eye with its work for Intellect Wireless Inc., a representation that led to costly sanctions against the Niro firm and its client.

Now, the fallout from that engagement has resulted in a U.S. Patent and Trademark Office suspension for one of the former Niro lawyers involved in an Intellect Wireless litigation campaign.
