AvantGo Gets a Patent
AnElder writes: "Yahoo's Daily News Technology section is carrying a story reporting that AvantGo has received a patent for its synchronization technology. And here's an excerpt: "In legal jargon, AvantGo said the U.S. Patent and Trademark Office had issued it patent No. 6,341,316 covering the system, method and computer program product for synchronizing content between a server
and a client." Why didn't I think of this?" In all fairness, the patent doesn't seem to be as bad as many that have been issued. It cites many other patents as references (which helps ensure that AvantGo is doing something *different*), and is rather specific about the process - I would expect that there are many ways to "synchronize" data that wouldn't run into this patent.
Link to the patent is here.
This patent looks to be worded broadly enough to cover Lotus Notes clientserver replication, which was developed around 1985. The only difference I can see is that Notes replication does not use XML or HTTP... obviously these were not available in 1985. I don't know if that's a material part of the patent claim.
I think Lotus has their own patents covering replication. I also know that some work was being done to leverage the Notes replication engine in the Internet world, (circa 1995) perhaps using HTTP or XML, but I can't prove this.
IBM, owner of Lotus and the world's largest patent holder, may have something to say about this patent.
While I was in college I did a co-op with a company that makes software to sync a certain popular PDA with Office. At the time, the company was really small and there were established competitors who were a lot larger than my employer. They, too, had a patent on a particular algorithm of synchronization, but we my bosses (one of whom was the developer of our software) weren't concerned. Our software was so much faster than theirs, the algorithm couldn't possibly be the same.
Imagine our surpise when our biggest competitor sent a "cease-and-desist" letter claiming we infringed on their patents. My bosses denied it, of course, but our competitor would have none of it. They had to see our code for themselves to verify that we weren't in violation of their patents. I don't quite remember exactly how it was resolved - I left soon after this became a big issue - but I'm sure it had something to do with my employer striking a deal with the manufacturer of the PDA.
Anyway, where I'm going with this is that, sure it might not seem like having this patent is a bad thing or over-reaching. And, used responsibly, it's probably not. But don't be surprised to see AvantGo try to get the drop on a potential competitor if they can use this patent as leverage.
My sigs always suck.
Claim 1: The client subscribes to aa set of content, the server gathers this content and later sends instructions to the client to transfer the content.
Claim 2: As above, but use a single message for the request and a single message for the transfer.
Claim 3: As 1, but also identifies "information that is of interest" during the sync.
Claim 4: Claim 1 where it happens over http. victim: I may become ill and stop typing this.
Claim 5: Claim 4 but transfer some XML on the HTTP. Yep, that's it. I can't go on. I mean no one would ever have considered transfering XML over HTTP! My GOD these people are geniuses!
There is nothing in this patent that a handful of competent engineers wouldn't come up with in their first brainstorming session.
I propose that the US Patent Office has so badly mismanged software patents that ALL software patents should be vacated and the patent examiners held personally liable for any damages claimed by the affected patent holders.
