By Nick Brown NEW YORK (Reuters) – Bankrupt LightSquared on Friday sued leaders in the GPS industry, including Deere & Co and Garmin International Inc, saying they kept mum about interference concerns stemming from LightSquared’s wireless network until the company had already pumped $4 billion into building it. In a 65-page lawsuit in U.S. Bankruptcy Court in New York, where LightSquared is fighting to keep control of its spectrum, the company alleged that farm equipment maker Deere, and GPS companies Garmin and Trimble Navigation Ltd led it to believe its network would not interfere with global positioning system devices. The complaint comes on the heels of a similar lawsuit against the GPS industry by Phil Falcone’s Harbinger Capital, LightSquared’s controlling shareholder. Last month, LightSquared received permission from the bankruptcy judge overseeing its Chapter 11 case to pause the Harbinger lawsuit so that LightSquared could decide whether it wanted to join the suit or bring claims of its own.
