Google has announced that AdWords keywords that were restricted as a result of a trademark investigation will no longer be restricted in China, Hong Kong, Macau, Taiwan, Australia, New Zealand, South Korea, and Brazil.

Google’s policy revision, which takes effect on 23 April 2013, follows its recent success in Australia litigation.

The High Court of Australia held that Google was not liable for any misleading use of the AdWords service by advertisers who pay Google to display sponsored links in response to search terms containing the trademarks of third parties.
