(R) II: Return to the USPTO
On July 12th, 2011, Haiku® received its registration with the United States Patent and Trademark Office (USPTO). This registration is for "Haiku" the name (as opposed to the HAIKU logo®, which became a registered trademark in March). More precisely, this new registration is known as a "standard character claim" and affords much more protection than the "stylized mark" registration of the logo.
Now for a quick crash course in trademarks. First, trademarks are specific to types of goods or types of services. As an example, our trademark registrations relate to computer operating systems, but not to washing powder. In layman's terms, a "stylized mark" is a specific representation of a trademark. In our case, the HAIKU logo consists of the word "HAIKU" in all uppercase letters, with 3 leaves that partially cover some of the letters. That registration is specific to that description (and similarly confusing marks). A "standard character claim" is more generalized, flexible, and stronger. That registration applies to any form that "haiku" can take -- whether it be as typed characters or a graphical representation.
So, back to the question that many of you may be wondering -- "What does this do for the Haiku Project?" It strenghtens everyone's ability to associate "Haiku" with the computer operating system that the Haiku Project creates. Additionally, it provides some artistic freedom. Let us imagine a purely hypothetical scenario to illustrate how this "standard character claim" registration provides that. Some years have passed and the project decides to create a completely new logo for Haiku. In this imaginary scenario, that new logo would be protected by the "standard character claim" registration. In short, it affords us the confidence that there will be only one operating system that can be called Haiku, no matter what the logo looks like.
Lastly as a reminder, Haiku, Inc. provides a page describing the trademarks and their proper usage.

Re: (R) II: Return to the USPTO
A minor nit to pick. Trade marks are specific to types of goods. Service marks are specific to types of services.
Of course, that raises a question. Suppose I were to open a shoppe and hang a shingle, "Fest3er's Computer Maintenance and Repair Service; specializing in the Haiku(TM) and Linux(TM) operating systems"; would that be an allowed use of the word mark? Or is it restrictive enough to bar folks in the service industry from 'advertising' their specialties?
Re: (R) II: Return to the USPTO
There are notions of fair use and nominative use which allow for such uses.
Re: (R) II: Return to the USPTO
I think you may have missed the point. I think it completely ok so have a sign that says "we service maytag appliances" that offering a service. What these trademarks refer to are the intellectual property under them, for instance someone could not do a linux fork and call it the "haiku'
These trademarks are about protecting the name and identity of haiku and supporting orginizations like Haiku inc.
There nothing in the trademark laws preventing you from opening a Disney watch Repair and Service shop.

Although, you may have to clarify that you are not an officially endorsed Disney watch repair specialist ;) Disney is pretty aggressive about trademark enforcement - not everyone is that aggressive.
Re: (R) II: Return to the USPTO
Disney is in a real pickle becuase copyrights only last for so long.
Re: (R) II: Return to the USPTO
Patents are short-lived: 17 years or so. Copyrights last the life of the author plus 50 years (in the UASR). That's a loooong time.
Re: (R) II: Return to the USPTO
1) Even if copyright mattered in this instance, they keep lengthening it every time Steamboat Willie's close to falling in the public domain anyways, and
2) It's entirely irrelevant because copyright != trademark. The latter has no expiration date as long as the trademark's in active use and being defended, unlike copyrights and/or patents.
