First of all, can you explain what an "open text" is?

Second, as far as I can find through the French IP office (INPI), OpenText (single word) is trademarked as a figurative trademark (meaning they are basically protecting the image of the logo), not a verbal trademark.[0]

Which is what you typically do when you know that your trademark is too likely to be rejected (as being too descriptive), but you want to give it a semblance of protection.

So, no, I wouldn't assume they have been treated better.
