Tellabs Sues Fujitsu for Patent Infringement

Tellabs Inc. (Nasdaq: TLAB; Frankfurt: BTLA) filed a patent infringement lawsuit against Fujitsu Ltd. (Tokyo: 6702; London: FUJ; OTC: FJTSY) yesterday in the U.S. District Court for the Northern District of Illinois. Tellabs is seeking unspecified monetary damages along with an injunction preventing Fujitsu from future use of the patents. (See Tellabs Sues Fujitsu.)

Tellabs alleges that Fujitsu is infringing on its patents within its ROADM systems and in its FLASHWAVE product line. The patent in question is No. 7369772 and covers methods by which optical line terminals (OLTs) can interact with metro WDM equipment.

But wait a second, didn’t we write a similar-sounding story back in January? With the company names in the headline reversed? It’s true, we did! (See Fujitsu Sues Tellabs .) Tellabs has now launched a suit claiming that Fujitsu that has been infringing one of its WDM patents, following a similar suit launched by Fujitsu in January. The patents in question, however, are not the same.

The patent in this new Tellabs suit is, in fact, different and much newer than those that Fujitsu originally filed suit against Tellabs for in January. It was registered on May 6, 2008.

Tellabs points out, however, that the patent was originally applied for in 2003. "Tellabs has been working on WDM for more than a decade and has invested more than $3 billion in that research and development," a company spokesperson says.

The Fujitsu lawsuit from January is a completely separate case from this new suit. The Tellabs spokesperson said the company is still fighting that lawsuit separately in court and believes the company is “in the clear, but will continue defending itself vigorously.”

Fujitsu could not immediately be reached for comment.

re: Tellabs Sues Fujitsu for Patent Infringement Bollocks,

Let's not leap into Tellabs bashing just yet. Fujitsu sues Tellabs on WDM and Tellabs sues Fujitsu on WDM. That's how it works in patent law. Tellabs and Fujitsu have numerious patents floating around and each is likely to violate from time to time. I expect most patent suits get settled out of court, by trading infringements. Big companies keep balanced and the big companies can bully the start-ups.

re: Tellabs Sues Fujitsu for Patent Infringement So why make it public - most of these patent swaps are done in private ?

The only bashing I am doing is the Lawyers & legal departments and finance folks are the morons in these high tech companies and they want to drag companies tor the courts to settle and say look we are working and making you money thats why you need to pay me so much.

The another company to do this was Telecordia sueing tellabs over SONET patents - look what happened to them.

re: Tellabs Sues Fujitsu for Patent Infringement You got a good point on the lawyer front. DSC was the Vanguard for Legal departments as a profit center. Shoot, when you can't inovate, litigate.

Busted is also likely right. When the behind the scene negotiations break down the next move is to take it public. It's not good or bad, it just is.

I just can't wait for the flood of Whaaway legal actions.

Cheers,
