The extensive litigation history, primarily between 2012 and 2016, indicates a significant enforcement campaign by NeoMedia Technologies. The consistent outcome of these cases being terminated, likely due to settlement, suggests that the defendants often chose to license the technology rather than proceed through a full trial. The patent itself, which covers a method of linking a physical item's barcode to an online resource via a database lookup, proved to be broadly applicable to the burgeoning field of mobile marketing and QR code applications, leading to these numerous assertions of infringement. As of the current date, there is no indication of active litigation involving this patent.
