AppleInsider wrote that Ameranth, a leading developer of internet and software solutions for the hospitality marketplace, filed suit against Apple’s Passbook digital ticketing app, claiming patent infringement in an ongoing effort to enforce its wireless technology IP. While Apple just launched the PassBook app which only supports a view apps, Ameranth lodged a complaint against Apple claiming infringement of four patents.

Ameranth “which manufactures and sells hospitality, entertainment, restaurant and food service IT solutions to a broad list of clients” filed a complaint in the U.S. District Court for the Southern District of California.

According to the complaint filed in the U.S. District Court for the Southern District of California, the Delaware corporation operating out of San Diego is asserting its “Information Management and Synchronous Communications” patent family, which the company claims “has been widely recognized as visionary.” Some 14 frims have already licensed patents in the portfolio and Ameranth has been aggressively pursuing legal action against big-name companies like Hilton, Marriott and Hyatt, for alleged infringement of the wireless synchronization patents.

At issue is Passbook’s ability to download and store airline boarding passes, hotel reservations, movie tickets and other digital passes on an iPhone or iPod touch. While the synchronization of pass data appears to be covered by Ameranth’s patents, the unique barcode-based redemption system is not mentioned in the suit or corresponding IP language.
