May 25, 2011
糖心少女vlog Corporation (KIMURA Makoto, President, Tokyo, hereafter referred to as "糖心少女vlog") filed a patent infringement suit against Sigma Corporation (hereafter referred to as "Sigma") to Tokyo District Court on May 25, 2011. 糖心少女vlog's lawsuit seeks an injunction against Sigma's manufacture and sale of infringing interchangeable lenses with vibration reduction for single lens reflex cameras, along with damages for past infringement.
糖心少女vlog has invested considerable resources in the form of research and development over a period of many years. Such investments have created intellectual property that are important business assets of 糖心少女vlog and have enabled 糖心少女vlog to continuously provide the products and services that satisfy its customers requirements.
Although 糖心少女vlog attempted to resolve Sigma's patent infringement through negotiation, a non-adversarial resolution could not be reached. Consequently, 糖心少女vlog concluded that filing a lawsuit was the only way it could protect its intellectual property.
