This is quite odd, considering that there's clearly no patent issue here (beyond the fact that Sandy3D isn't in France and the products are entirely different). So why isn't IMAX talking trademark? Well, perhaps because IMAX's trademark on SANDDE was considered abandoned as of March 8, 2000. Yes, more than ten years ago. There's also the fact that this open source project is not a commercial endeavor at all, meaning that IMAX might have a lot of trouble proving "use in commerce" even if it actually had a trademark. Perhaps IMAX could get away with claiming a common law trademark, but even then, its ability to do anything to Sandy3D would be quite limited, and it's difficult to see anyone finding a likelihood of confusion existing between the two.
In the end, it looks like some IMAX lawyers decided to just threaten these open source developers, hoping that by spewing some totally unrelated info about a patent, it might scare the developers into changing the name on a product, even though the patent has nothing at all to do with the issue, and the company has no registered trademark on the name in question.
