Google's free Web email offering may be available for correspondence in 40 languages, but efforts at worldwide expansion using the moniker "Gmail" continue to face complications.

Last October, the search giant grabbed headlines — and miffed some British users — when it voluntarily renamed its service "Google Mail" in the UK, following an out-of-court trademark dispute.

The woes don't end there. Across western Europe, a quiet battle rages on between Google and Daniel Giersch, a German-born venture capitalist who insists he'll never relinquish his six-year-old trademark registration of "G-mail...und die Post geht richtig ab" (translation: G-mail... and the mail goes right off).

"Google's behaviour is very threatening, very aggressive and very unfaithful, and to me, it's very evil," he said in a recent telephone interview with ZDNet UK’s sister site CNET News.com from his part-time Los Angeles home.

A Hamburg district court has already handed Giersch victories at both the preliminary and final stages of the litigation. Dismissing Google's arguments that the two names are not confusingly similar, it ordered the company earlier this year to remove all "Gmail" references from its German service and to cease handing out gmail.com aliases to users within the geographic area.

Buoyed by that success, Giersch said he plans new lawsuits to defend more recent registrations of the trademark in Switzerland, Norway and Monaco, where he hopes to expand his electronic postal delivery business that goes by the G-mail (short for "Giersch mail") name. He said he is also considering a suit in the US based on alleged "investment losses" that the overseas disputes have wrought on the American arm of his venture capital firm. (Google has already encountered competition for the US trademark.)

Google still maintains it has clear rights to use the Gmail name in Germany and in countries throughout the world where it has applied for such trademark rights. It lodged an appeal against the Hamburg district court's decision but claims it has nevertheless been abiding by the orders to restrict all people determined to be German residents to use only googlemail.com, ever since a preliminary injunction was issued in April 2005.

"In no case do we offer or allow a user to use '@gmail.com' if the user's IP address is German," a company representative said in an email interview.

Google has initiated its own actions against the 32-year-old Giersch in other European countries since the German litigation began, asserting it has prior rights to the Gmail name and that Giersch's registration attempts should be blocked. Giersch's lawyers said the company has filed — so far, unsuccessfully — for a cancellation of his Norwegian holding with the country's trademark office. The Google representative would confirm only that a court challenge is pending against the Swiss trademark, adding that "there are a number of cases outstanding against Giersch in Europe".

For the search market leader, the rationale is simple: "Google will take the action it deems necessary to protect our interests in Europe," the company representative said.

Google vs Giersch
Sergey Brin and Larry Page started Google with a home-brewed data centre in a dorm room. For Daniel Giersch's venture, it was a backpack and a bicycle.

When he was 18, Giersch founded his first company, a same-day mail delivery service designed to offer a swifter alternative to the Deutsche Post. Within a few years, by his estimation, the company was delivering 80 percent of the mail within his hometown of Itzehoe, a town of about 30,000 residents near Hamburg.

Giersch ultimately sold control of the physical delivery operations and started on a new venture he called "hybrid mail". The idea is to combine the relative security of physical mail delivery with the speediness of email. A sender's document is scanned into Giersch's system at its origin, transmitted electronically to a G-mail office in the destination city, printed out at the other end and hand-delivered to its recipient. Giersch also offers users a "secure" gmail.de address, which they can obtain only by verifying their identities with a passport or other official ID card — a far different business model from Google's Gmail, he said.

In 2000, Giersch registered "G-mail... und die Post geht richtig ab" with the German trademark office. He was still investing in and developing his hybrid mail service four years later (in Germany, one has five years after registering a trademark to commercialise its use), when he saw news reports that Google planned to launch a Web email service named Gmail. Google's email service debuted in April 2004.

"Knowing Google is very powerful, I liked it at the time; I Googled myself everyday. I said, 'you know what? I want to call these guys,'" Giersch said in a telephone interview. "I did my MBA, and I know what a big company is looking for, and that is international growth. I knew sooner or later they would go to Germany."

After rebuffing his initial attempts to talk over the situation, Google eventually offered to buy the German trademark rights for $250,000, Giersch said. But by then, turned off by what he deemed "arrogance" on the search giant's part, he had decided never to settle. When Google started offering…

Its obvious that most of the people are sensible enough to get a trademark or patent for their works so that others cannot steal their credits in future. This is not gonna be a big set back for google, they are the big cash guys, they'd buy it what ever price is quoted.

Lets wait and see whats gonna happen out there.
