Looks like Oracle might not own the trademark to Hudson after all: The Register says that Oracle filed for the trademark (in the EU, at least) after discussion started about a move to github.
...a well-placed former Sun Microsystems employee has contacted The Regto say that Sun took an "explicit decision" not to apply for a trademark on the name Hudson. A search of the US Patent and Trademark Office's website throws up 623 trademarks for Hudson for many things, but not for the project Oracle owns.
Oracle's making a customer grab here (from "Oracle claims trademark on Hudson open source"):
These are customers that Oracles wants. It wants to tie them to its own developer and tools roadmap. It's not clear what plans Oracle has for Hudson, but there's every possibility Oracle would like to have Hudson integrated through Kenai with its own Java IDE and tools JDeveloper.
There's nothing wrong with wanting to expand markets and customer bases. There is something wrong with retroactively declaring ownership of something just because it represents an opportunity.
The wrong is magnified when it's perpetrated against Kohsuke Kawaguchi, who through all this has been very respectful, quiet, honorable. In private conversation, he hasn't asserted whether Oracle owns the patent or not, even though if anyone owns the trademark, it should be him.
However, he might not: Oracle might be able to claim that Hudson was a formal part of Kohsuke's work product (when it was first written, of course.) If he was employed for the purpose of writing a build system, then it would be Sun's trademark, and therefore Oracle's.
That said, it's not clear if that's the case, and nobody at Oracle has said anything conclusive that I've been able to find. (Except Mr. Farrell, but I am discounting his statements because they seem to be factually in error, or at the very least built on assumption and would be accurate by accident.)
Now we get to wait and see further. Yesterday, Mr. Kawaguchi announced that there would be news on Hudson after the weekend; did Oracle file the trademark in the EU in the interim? If so, the news would be the standard "Oracle is evil, and they're likely to get what they want by fiat."
Let's hope not.
The worst thing is that there's no real recourse outside of either a schism in the Hudson community or total surrender. OpenOffice and Solaris have already been sacrificed with the former strategy; let's hope Hudson isn't added to that list.
