Ironically it was the decision to invest heavily on a technical innovation over a revolutionary invention, the ballpoint pen, to inflict a mortal blow to the company. In 1945 the Eversharp began to take an interest in the development of the ballpoint pen acquiring the rights to use the Biro pen the by Argentine producer Eterpen Co., but before the launch of its CA (Capillary Action) another company, the Reynold's International Pen Company put on the market another ballpoint pen. That gave rise to a furious legal battle, that was lost since the invention was already covered by an expired patent from 1888
