WASHINGTON (CNN) -- First came the iPhone. Then, there was the "iFart" flatulence noise download. Now, there's "Pull My Finger" -- and next could come the lawsuits.
A Florida-based company has accused a Colorado competitor in federal court of trademark infringement and unfair business practices over the phrase "Pull My Finger."
The dispute began after the makers of iFart began using phrase "pull my finger" in advertisements for their products.
Air-o-Matic, based in Jacksonville, Florida, and Colorado-based InfoMedia, Inc., both offer a range of competing software applications, or "apps," that subscribers can download into their multitasking cell phones. Users can make calls, listen to music, browse the Internet and play games on the devices.
Individual "apps" cost a dollar and up, and can be used to get directions, read restaurant reviews and make funny noises. Enter the flatulence sound app, which both companies offer to customers.
