Cisco Sued over OFDM Wireless Standards 142
Agent Green writes "It's definitely not the first time someone has been sued over a standard, but Wi-LAN is in the process of taking Cisco to court over the OFDM encoding which it claims to have patents for - the standards in question apply to 802.11a/g. Interestingly, this case is being brought in Canada, where the defense needs to prove its case. Might be time to join and expand the patent busting brigade?"

A pretty sounding but faulty argument that patent supporters like to use. Retrospective assessment, by definition, will have more facts available to make a judgment and therefore will be a better judgement.True innovation is obvious both pre- and post- innovation.
Often, so-called innovation is merely an idea whose time has come that will be invented independently in a short period of time by many people with no so-called "prior art". None. The the patent office gives a monopoly to one "inventor", sometimes giving them a multi-million dollar advantage, and penalises many others who've done exactly the same thing. Yet another example of how unfair the patent system is.
If the patent system truly reflected the reality of IP invention rather than some lawyer fiction at a minimum it would allow multiple near simultaneous invention. It would also not make "prior art" the definition of innovation but "obvious to an expert in the field" (not some patent office non-inventor) instead. In addition it would also assume that simultaneous inventors are innocent of copying until proven guilty with a chain of evidence, like most law.

Wrong. And yes, I was horrified when I discovered this too. But it's really common for an industry standard to contain patented technologies. For example, many emerging communications standards are employing Turbo codes (which have been mentioned on Slashdot before, with various degrees of cluefulness). Now these were invented quite recently, by some French researchers, and they perform incredibly well. But in order to implement these standards, you (or your supplier, or their supplier) have to pay royalties.
The approval committees never actually infringe any patents, so they aren't a sensible target for litigation. They are, however, a sensible target for loud and persistent complaints about patents-in-standards. Most of them have vested interests in the big companies who implement the standards anyway, so don't hold your breath for a change of heart which might actually encourage competition in those markets.

FYI here [uspto.gov] is the patent which covers that work. My name is not on it. At the time, it was the concept of a wireless version of Ethernet that was seen to be novel. Others had low speed networks (packet radio). High speed wireless point-to-point links also existed. As far as we knew, noone had yet tried to build something that was a network AND high speed.
Anyway, that was my understanding at the time. As is usual, most parties were playing their cards close to their chest, so there could have been others. The only other one I knew of at the time was the Bereley InfoPad. I'll be as interested as anyone else to see of the patent survives the challenge.

Ok as a serious argument though, this comment from one of the Ethernet pioneers is interesting:
"David Liddle, now general partner at U.S. Venture Partners, said Xerox charged a one-time license fee of just $1,000. That's in contrast to the huge fees associated with Token Ring.
Xerox's stipulation was that the technology couldn't be changed -- it had to interoperate with all other Ethernet implementations. "Thus we made a playing field in which we could all thrive and compete," Liddle said"

Its interesting because its today's argument happening 20 years ago - IBM attempting to turn a token-ring into a cash cow (like today's patent shills) turned people away from it as a standard, and Ethernet won - admittedly with a 'RAND' approach, not a patent-free approach.

So, assuming that Cisco had to stop selling in Canada and instead sold in just the United States and Europe (ignoring Asia, Australia, etc., entirely), their sales would decrease by less than 5% (35/708). Wouldn't it be reasonable for them to just ignore this lawsuit, and in the meantime continue selling in Canada? If the government eventually forces them to stop, it'd really be no particularly big loss, except to Canada--who would no longer have access to Cisco technology. Which would therefore make the government unlikely to stop Cisco from selling there. Seems like Cisco holds all the cards, here.
