Announcing Software Patent of the Week

by on June 16, 2006

As regular readers of TLF know, I’m not a big fan of software patents. The more I learn about them, the more I’m amazed at the sheer scope of the problem. Every month, thousands of new software patents are issued. And at any given time there are dozens of software patent lawsuits before the courts. A few of them get big headlines, but most of them are never reported outside of the tech press.

So I’ve decided to do my small part to publicize the scope of the problem: every week, on Friday, I’m going to feature and analyze a software patent. In most cases, they’ll be software patents that are the subject of current litigation. My purpose for each weeks post will be to answer the questions: is this an obvious patent? And do patents like this promote innovation?

There’s enough software patent litigation out there that I don’t expect it to be that difficult to find a new case to highlight each week. But it would be a lot easier with help. So if you know of an example of an interesting software patent case–good or bad–shoot me an email at tlee -at- and let me know about it.

In the future, this post will also serve as an index to the Software Patent of the Week series. Each week, I’ll add the latest software patent to this list, so that people can easily find the whole series.
