Wireless Patent Issues

Once again, the US Patent Office lets something through its doors thats causing problems all over the place. Patent Number 5487069 seems to have the following abstract:

The present invention discloses a wireless LAN, a peer-to-peer wireless LAN, a wireless transceiver and a method of transmitting data, all of which are capable of operating at frequencies in excess of 10 GHz and in multipath transmission environments. This is achieved by a combination of techniques which enable adequate performance in the presence of multipath transmission paths where the reciprocal of the information bit rate of the transmission is short relative to the time delay differences between significant ones of the multipath transmission paths. In the LANs the mobile transceivers are each connected to, and powered by, a corresponding portable electronic device with computational ability.

The underlined portion of that quote seems to be what the judge decided to agree with when CSIRO (which I’ve nicknamed Crisco since I just woke up and can’t see straight) when they sued Buffalo Technology.

On the other side of the spectrum (pardon the pun), please tell me where my Wireless Router states that its operating in the 10GHz environment… Seriously. The sticker that I left on the thing says 2.4GHz just like most of the other routers of the world. The judge decided to ignore the number and paid more attention to one sentence. I guess the “which are capable” is what causes the problem, right?

Now “Crisco” is stating they’re planning on going after Netgear, Microsoft, Dell, Intel, etc…
