A friend of mine received a C&D letter from a lawyer representing the site that ranks aove him in the SERPs. He's had the domain name for like 3 years now and for the last 6 months has been ranking #3/#2 for it's main keyword (the url is the exact match of this keyword). The first 18 months or so it was ranking on the 2nd page. Supposedly the site that ranks #1 and #2 has a trademark on words that that make up kw1 and kw2 of the main keyword (which is "kw1 kw2 kw3")..so the domain is "kw1kw2kw3[dot]net". They have told him to immediately take down the site so that it does not resolve. And also to remove any references to the "kw1 kw2", and so forth. The letter has given him 2 weeks to comply and to write back showing them that he has take down the site and is no longer the owner. Now my question is whether he can do anything to stop this? Any way to work with them and still retain the site? Could he sell the site on flippa and let the new owners deal with it? Or there isn't anything to do but let go of the site and move on? Anyway to make any sort of money out of this situation? The site makes about $15-$25/day Adsense. I think what might have triggered this is that he got many emails daily for this product from people that visited his site, but he actually never responded to any. Later on he got emails of why the company was not responding to any of their emails. What if he starts another site, but this time does not use the trademark keywords in his top level domain, but rather as internal pages (so "generickeyword[dot]com/kw1kw2kw3". Would they come after him again or is this mostly due to having the trademark name in the top level domain? Anyone have any experience with this sort of thing?
