Trademarks on free software are anathema to the cause of free software and constitute a threat to the future of free software that slows the adoption and innovation that could result otherwise. Free software can form ecosystems that evolve. Retaining the same or similar names for related software encourages that evolution more than forcing forked applications to change names. This is exactly the view that free software is built on. It is only proprietary interests that have forced trademarks into the free software world. And this is a future problem that the free software world is going to have to deal with more and more, just as it has to look more closely at patent issues than it did in the past.

The OmegaT project claims to have a trademark on the term OmegaT. The validity of this claim, to date, can only be shown to extend to use of the term in Germany. OmegaT provided the registration number (306017997) of the trademark and the related documentation can be found at the relevant government site (search it).

OmegaT members have tried to use this fact as a mechanism to propagate slanderous accusations against OmegaT+ and launch personal attacks for using a variation of it on another piece of free open source software. At the same time, they make no efforts to clearly represent the actual extent of the trademark to the public. When asked, they only state that OmegaT is a trademark, but not where it applies. Thus, this could be viewed as an attempt to mislead the public by not providing information in a transparent manner. When asked if it is an international trademark, no response is ever given. A case of deception by obscurity may be at hand.

Regardless, the OmegaT+ project has been using the terms omegat and OmegaT+ for more almost six years in various places and on different software products without issue, aside from the threats and wrangling of disgruntled people associated with OmegaT. That includes right here on this page without the need for any trademark symbols that are necessary when the force of a trademark is really in effect. Obviously, their efforts carry little weight in regard to their claims.

Logo images and others produced for OmegaT+ can be considered trademarks of myself and this project if used in conjunction with products that are of lesser quality for the same or future versions of the software (no passing-off). Otherwise, they can be used in the same sense that copyrighted GPL software can (unmodified and positively modified distribution).
