Eyeo, the company that operates the Adblock software, has had its work vindicated in the German courts and its services deemed legal.
The firm, specifically its Adblock Plus software which strips advertising content from websites, was challenged by two German publishers and accused of illegally affecting their businesses.
Zeit Online and Handelsblatt, publishers of websites Zeit.de, Handelsblatt.com and Wiwo.de, had alleged that the software acts illegally in blocking adverts and sought an injunction.
A four-month trial followed but a court in Hamburg ruled in favour of the company and its software this week. Eyeo welcomed the decision, and used the opportunity to say that it offers more than just advertising blocking.
"Today, after a four-month trial, reasonable heads prevailed as the regional court in Hamburg ruled in Adblock's favour by declaring that ad blocking is perfectly legal," said the firm in a blog post.
"I know it's restating the obvious. But it cost us lots of blood, sweat and tears nonetheless."
The Hamburg court decision is important, according to Adblock, because it sets a precedent that may avoid additional lawsuits and expenses "defending what we feel is an obvious consumer right: giving people the ability to control their own screens by letting them block annoying ads and protect their privacy".
The firm added that the purpose of the software is not to part publishers from advertising money, but is actually a tool and a resource that they can use to better serve and target consumers.
Adblock appealed to publishers and other companies for cooperation. "Now that the legalities are out of the way, we want to reach out to other publishers, advertisers and content creators and encourage them to work with Adblock Plus rather than against us," the firm added.
"Let's develop new forms of non-intrusive ads that are actually useful and welcomed by users. Let's discover ways to make better ads. Let's push forward to create a more sustainable internet ecosystem for everyone. You know where to reach us."
