The email from Eyeo implies it owns "Adblock" trademarks in Brazil, China, Russia, and Taiwan. And this is the Adblock Plus mark registered with the United States Patent and Trademark Office. Here are Adblock Plus' European Community Trademarks, which include a mark for "Adblock Plus" and the company's various logos, including one for the "Adblock Browser," but not the word "adblock" on its own.

The policy states that developers must agree their software does not violate "intellectual property rights, including patent, copyright, trademark, trad secret, or other proprietary right of any party." The app can be resubmitted for inclusion once the issues have been addressed." Actually, most of the ad blockers in Chrome Web Store include the word 'adblock'."Ī Google spokesperson told Business Insider: "While we won't comment on specific apps, if an app breaks our Google Chrome Web policies, we'll remove it from the store and inform the developer. He added: "We named it Adblock Ultimate, because we believe 'adblock' is the common term for blocking ads in any browser. Georgiev, however, feels Adblock Ultimate is a "victim" of a "ridiculous" complaint, forcing it to change its name "for absolutely no reason." Therefore we would have to request you to change the name of your product to something that does not include "Adblock", "Adblock Plus" and/or "ABP". So we do not offer any trademark related license agreement at the moment besides our own products.

We need to protect our users from getting confused. As a result of such long-term use, advertising and expenditures, Adblock Plus has established considerable goodwill in the ADBLOCK® Marks. But Adblock Plus has continuously used the ADBLOCK® Marks since January 2006 in the United States and throughout the world, and has invested and continues to invest heavily to develop and enhance the fame of the ADBLOCK® Marks.

We understand that your company uses the name “AdBlock” in connection with its advertisement screening software.
