This story was amusing. Someone is claiming to own the trademark to “Python” in Europe, covering all usage of the word “Python” in computers or software. They are not related to the Python programming language. If they succeed, it would prevent people from using the word “Python” to refer to the programming language, without permission of that trademark troll.
Obviously, based on merit, the trademark should not succeed. However, it will be decided by whoever has the better lawyers, rather than based on merit. Even if the trademark troll fails, he forced people to waste time and money fighting him.
This is the problem with trademarks. Nobody should own the right to use a specific word or phrase. It would be offensive to use a name that conflicted with an established business, but it shouldn’t be illegal. If you picked a confusing name for your business, you would be liable for fraud if you confused your customers.
Intellectual property is not a valid form of property.
