Companies getting more savvy to TM infringers, guided by industry peers and battle hardened IP counsel. Not all cases are as clear cut as this one Download wpp-polaris.pdf .. I expect some legal pushback as the first registrant's located in juridictions where ACPA doesn't apply, start to fight back using a twist of arguments found in old cases such as webber grills (although that criteria was different) and draw on the inequity of search engine monetization of those same TM's via Google/Yahoo paid-search.
For years domain registrants have been preaching about the value and worth of domain names. In a classic example of: "be careful what you wish for.. you may get what you want", companies around the world are starting to recognize that value .. and are moving to secure the rights to obvious infringements of their brands/marks first.
