Lawsuit targets Apple, HP, others over Wi-Fi antennas

updated 10:45 am EDT, Wed May 18, 2011

Apple case focuses on MacBooks, AirPort

A new lawsuit is accusing Apple, HP and several other companies of violating patents related to Wi-Fi antennas. Filed by Linex Technologies, the case specifically targets the defendants for breaking US patents 6,757,322 and RE 42,219, titled Space diversity and coding, spectrum antenna and method and Multiple-input multiple-output (MIMO) spread spectrum system and method, respectively. "Defendants' Accused Products infringe the asserted claims by receiving and processing multiple spatial streams using multiple receive antennas," a critical part of Linex's complaint reads. "The infringing MIMO mode is described in, for example, Table 20-30 and related portions of the IEEE 802.11n standard."

Offending Apple products named in court documents include the MacBook, MacBook Air, MacBook Pro, AirPort Extreme and Time Capsule. The HP products mentioned cover servers, consumer-level PCs and the MediaSmart LCD TV. The lesser-known defendants in the case are Aruba Networks, Meru Networks, and Ruckus Wireless.

Linex is asking for damage compensation, as well as an injunction against the sale of infringing products. A more likely outcome is a settlement or dismissal, as a protracted legal battle would be expensive for both parties.

    Speaking of Time

    I had to look to see when the Airport Extreme was released, and it was before the first patent was filed. So yeah, good luck with that.

    First airport didn't have MIMO. it was only 802.11B

    I would not bother with this...

    ...too much if I were Apple.

    It is well known iPhone's antennas are there just for looks, no reason to copy anything from this troll!

    Well except for the one used for tracking the iPeople!
    But that's another story...
