Sentius Revives Spellcheck Campaign Against Smartphone Makers

August 12, 2018

Sentius International, LLC has rebooted its litigation campaign, filing two new lawsuits, one each against HTC (1:18-cv-01216) and LG Electronics (LGE) (1:18-cv-01217) in the District of Delaware. The complaints assert only one of the two reissued patents most recently at issue in this campaign; in the NPE's last open case, filed in the Eastern District of Texas against BlackBerry, District Judge Rodney Gilstrap invalidated the sole asserted claim from the other patent for impermissible claim broadening through reissue proceedings. Both patents generally concern parsing and annotating document text, with the defendants accused of infringement through the provision of smartphones, along with certain preinstalled apps that allow text entry, and their systemwide spell-check features that highlight misspelled words and present suggested corrections.
