Re: Time to lawyer up
You may want to look for European Trademark 010848208. Applicant is POBox Hosting.
That said: It seems to be a composite mark, i.e. it has a word component "PYTHON" and a pictorial component (circle, colour, all caps typeface). It seems to be more targeted to web hosting but contains a claim to computer software.
"A community trademark lasts 10 years and would grant Veber exclusive ownership of the name Python in all European Union member counties.
It would prevent anybody else from using the word “Python” in goods, packaging, services, or in business papers and advertising without Veber’s express consent. Doing so would breach the trademark and entitle Veber to prosecute."
That is not certain yet. First of all, a trademark is only going to give rise to claims for the goods and services it is registered for or for which there is a likelihood of confusion. If the trademark is famous for the applicant (a quite high proportion of the public associates the trademark with the goods and services of the applicant), then it can monopolize a word also for other goods and services.
But does this trademark really go so far as to monopolize "PYTHON" for software? Or does it only protect the specific registered form? We are yet to find out.
Interestingly, there is also EM003098101, which is a word mark.
