City Sued Over Smart Meter-Related Patent (chicagotribune.com)

New submitter wb8nbs writes: Florida patent troll Atlas LLC has filed a suit against the municipality of Naperville, Illinois (paywalled). Atlas claims infringement of their patent on wireless communication where a hub node controls remote node responses. In 2011-2013 Naperville, which owns the local electrical utility network, installed Smart Meters on nearly all customers in its serving area, a move that was bitterly opposed by a small group of residents. The Naperville Smart Meter network uses Zigbee protocol to return readings to their fiber optic collection network. The Atlas suit could have long range implications to the Internet of Things, but it appears they have sued and lost a similar case in Florida.

OK I looked this up.

[hey!]

Here is the complaint: https://www.unitedstatescourts.org/federal/ilnd/318734/1-0.html.

Here is the patent in question: http://www.google.com/patents/US5371734.

Basically the patent describes a time division wireless networking scheme in which certain nodes orchestrate transmission and receiving time slots assigned to adjacent nodes. The claimed benefits of this scheme amount to these: bandwidth can be allocated to nodes dynamically, and nodes can extend battery life by turning off their receivers when it's not their turn to receive data. I have no strong opinions as to whether the networking scheme as so vaguely described in the patent is original enough to be patented, but the complaint is a different matter. It appears that Atlas IP LLC appears claiming that any system in which devices are polled and in which the devices may not be transmitting or receiving at any time infringes on this patent. If that is what the patent means, then clearly it's too obvious to be "original".
