When e-Parcel Corp., an online data delivery service provider, last year sued 13 U.S. Internet-related service firms, including Yahoo Inc., Google Inc., AOL Inc. and Akamai Technologies Inc., for patent infringement, the action meant more than just protecting its intellectual property.

The president of the Tokyo-based venture says he wanted to prove that the company's technologies are the de facto global standard. Joji Kitano's primary target for this message was the conservative domestic market, which he says is closed to newcomers.

"If we can prove (through the lawsuits) that companies like Google and AOL are using our technologies, Japanese companies can trust us and introduce the technologies as well," Kitano told The Japan Times in a recent interview.
