Smartflash filed a lawsuit against Apple and various tech companies, including HTC, Samsung, and Google, in 2013 and 2014. The lawsuit alleged Apple's iTunes Store, App Store, and iAd violated three Smartflash patents related to "data storage and managing access through payment systems." The company was founded by inventor Patrick Racz, who invented Data Storage and Access Systems technology, which he called "Smartflash", but the firm's activity is patent licencing, which triggered the critics to call it a patent troll. But his February victory wasn't enough for Racz; he filed another lawsuit against Apple in the same court, involving the same patents but addressing products not included in the first filing. Apple, of course, appealed against the ruling and used the case to highlight inadequacies in the US patent system and called for reform to eliminate, or at least limit, the activity of companies who make money on patent royalties instead of making products.
