Here is something that raises an eyeborw…..Nortel (A large Public Company) put together a shortlived new ad campaign targeting Cisco with Domains using Cisco’s Trademark like; ciscoenergytax.com and yourciscoenergytax.com
Here is an excerpt from the WSJ:

“Nortel, which normally relies on conventional media campaigns, has taken more of an edge this time to leverage its marketing budget. It has linked to bloggers, launched a Web-based “energy efficiency calculator,” even posted grainy trade-show videos on YouTube.

Cisco isn’t amused. As part of its marketing campaign, Nortel bought the Internet domain names “ciscoenergytax.com” and “yourciscoenergytax.com.” Cisco complained to Nortel, saying it was a trademark violation. Nortel relented and gave up the names.”

That would have been a Wipo to watch…
