The iPint application on the App Store has been caught in a legal tussle between developer and beer maker, AdAge reports. iBeer developer Hottrix alleges the Carling-branded iPint application is a near copy of their application and was only made after Hottrix rejected a request to develop the application for them. Hottrix filed a $12.5 million lawsuit against Molson Coors Brewing Co. in Los Angeles County on Friday, claiming the free iPint application dramatically cut into sales of the iBeer look-alike. The suit claims iPint has been downloaded at least 6 million times (mind you, Apple (NSDQ: AAPL) is estimating 10 million iPhone users by year-end, although there could be that many today). After Hottrix lawyers couldn’t reach an agreement with Coors following iPint’s release, the developer successfully lobbied Apple to remove the application from the App Store in the U.S., however it’s still available abroad. But more importantly, will Hottrix be able to prove that sales of the $3 iBeer application would ever approach $12.5 million? That’s a lot of revenue for an application that simply mimics the pouring of a beer, something, which by the way, you can do for real for about a buck.
