The patent- originally filed in March of 2005 appears to encompass the characteristics of what was Ruyan's E-gar and then "morphed" into various "disposable" products manufactured and sold by them. It would appear to be the basis for just about every disposable e-cigarette currently on the market. Nothing groundbreaking here- but this could cause real problems for US importers across the board and could, potentially, have a serious negative impact on the retail supply chain.
