Hi, I'm new to this list, so maybe I should introduce myself. I'm a Debian user since 1.3 (or something like that, my first CD set is 2.0). I live in Berlin/Germany, and I have studied law. Currently I am a "Rechtsreferendar", that's something like a mandatory trainee phase before one is allowed to work in legal professions in Germany.

But the trademark issue might remain. I don't really know US laws for this, but in Germany one might argue that PHP is a notorious trademark according to § 4 Nr.2 MarkenG. And this could mean an exclusive right for the PHP group to use the PHP mark and those that can be confused with their mark. This includes marks that wrongly suggests a relation between a product and the protected mark (§14 II Nr. 2 MarkenG). So if the PHP group was enforcing their trademark, this could be a potential problem, at least in Germany. (I have heard that in the USA, there is a "common law trademark", this might lead to a comparable issue.) On the other hand, I did a quick search for registered trademarks containing PHP, and there is quite a number of them, names like "PHP Magazine", "Visual PHP", "PHPED". See http://oami.eu.int/CTMOnline/ for EU-wide trademarks. If a trademark owner doesn't act against such uses of his mark, the trademark (PHP) is "watered down", so it isn't that strongly protected anymore, because the relevant customers are used to seeing products with a related name that are not issued by PHP group. So if the PHP group took the phpbb team to court in Germany, I could't tell without further research who would win. Maybe one should ask the PHP group to clarify if their claim only applies to derived works, or if they are trying to enforce trademark rights on any use of "PHP". If it's the latter, Debian might have to worry about it... Michael Below
