IBM Says Twitter Infringes Three Patents

Just days away from the company’s initial public offering, Twitter disclosed that multi-national computing conglomerate IBM is claiming Twitter has infringed upon its existing intellectual property. The news, which came as a brief aside in Twitter’s latest S-1 amendment filing with the Securities and Exchange Commission, signals Twitter’s first big step into the aggressive landscape of technology patent litigation in Silicon Valley, a place where companies like Google, Oracle, Apple and Samsung lobby suits back and forth on a regular basis.
