Background

JMRI Defense: Articles by Others

This dispute has attracted attention, even outside the model railroad community. On October 1, 2008, for example, doing a Google search for "JMRI Katzer" found 2,790 pages.

On this page, we list some of the articles and other discussions found on the web. The list is by no means complete!

A recent article in Datamation by Bruce Perens is particularly interesting.

Software Patent Aspects

  • An entry in the Right-To-Create blog created the first major attention when it was highlighted on Digg. There was also an detailed update in April 2006, and then another short update in May 2006.
  • Pamela Jones wrote an excellent article for LWN which was later made available on Groklaw. This is perhaps the best introduction to the issues, and carries some interesting discussion in the comments. For example, this item raises the question of how open-source software communities can defeat a divide-and-conquer strategy such as the one being used here against JMRI.
  • Esther Schindler wrote an article for Software Development that was syndicated widely.
  • A brief note on the Patent08 blog in April 2006 provided a nice summary of the case.
  • In June 2006, Bruce Perens wrote a very interesting article on Technocrat.net about the "Monster" of patent litigation against free and open-source software, using the JMRI and Red Hat patent cases as his two examples. It's a good introduction to the larger issues. It's been referenced in articles all over the world; here's a commentary in Italian, for example.
  • When the story was picked up by Slashdot in June, it rapidly reached 400 comments from readers.
  • Another article by a patent attorney discussed aspects of the case in June.
  • In September, the Information Week web site carried an article about software patents that used the JMRI case as an example of abuse. The case was used as an example in another article about patents at the Supreme Court.
  • In December 2006, Jim Farmer presented a talk on Patents: Is Open Source Endangered? at the JASIG Conference in Atlanta that used the JMRI case as an example of the chilling effect of patents. JASIG is a group of educators and universities interested in collaborating on open-source educational technology. A talk with similar themes was given by Michael Feldstein at the April 2007 conference on Open Source, Learning, and Patents in Washington DC.

Copyright Aspects

The copyright aspects were originally discussed on Slashdot in November 2006, but there wasn't a lot of general interest at that point.

The August 2007 decision denying our request for a preliminary injunction on copyright, and even questioning whether copyright is available for Open Source projects that use "non-exclusive licenses", generated much more attention. The first article was on Mark Radcliffe's Law & Life: Silicon Valley blog on August 22, 2007. Evan Brown's Internet Cases site carried a somewhat different analysis the next day.

This was followed by an article in The Register, closely followed by coverage in a number of places:

  • Article in DZone (General developer web site)
  • Article on a Freeth Cartwright blog, which unfortunately omits the fact that Katzer removed the JMRI copyright notices. (A correction was submitted, but they have not decided to posted it on their web page)
  • Brief item on the OpenSource Legal website.
  • Article on The Converging Network site.
  • Item on the Association for Competitive Technology blog (Some information on who they are)
  • Article in German.
  • There's a long discussion from several perspectives in the responses to a Slashdot article, which had the side-effect of driving 10's of thousands of readers to the JMRI web site.
As time went on, longer and more detailed discussions appeared: Eventually, there were even articles in legal journals such as the North Carolina Journal of Law & Technology.

As the Federal Circuit appeal progressed, there was some web discussion:

Reaction to Appeals Ruling

The Court of Appeals for the Federal Circuit decision upholding our position got some immediate attention: There's a nice article about the decision on Groklaw, with some detailed commentary (scroll past the text of the decision).

Then it hit SlashDot in a well-written item that of course caused much discussion.

Comments in mainstream media:

Computer industry media:

Model railroad specific:

Some more selected statements, posts and discussions:

There have been articles in German, Dutch, Polish, French, Hebrew, Dutch and Russian.

Only 24 hours after the decision was released, Google found 577 new hits on the search string "jacobsen katzer open source decision".

The Wikipedia Article on the Artistic License has been updated to include this case, and somebody created an article about the case itself.

By mid-September 2008, the case had attracted enough interest that it became the topic of Continuing Legal Education classes:

It's great that the AIPLA considers JMRI's victory over Katzer's incorrect copyright arguments as one of the "Hot Topics of 2008".

As time goes on, more thorough articles have started to emerge. Not all the facts in these are correct, but they do make some thought provoking points:

Larry Rosen will be presenting a paper at several intellectual property conferences, and posted a copy on his website.

Bruce Perens wrote an article in Datamation magazine. You have to love an article that refers to Matt Katzer as "the worst enemy a Free Software project could have", because "Katzer's quest for money has so far only resulted in making Open Source stronger, while so far gaining Katzer nothing". (This article was also slashdotted resulting in almost a hundred-thousand accesses to the JMRI web site; that really spreads the word!)

Michael Swaine wrote an article for Dr. Dobb's covering this case. It makes an interesting point that model railroading is where free software begain.
