It is good to know that Google settles suit over ad keywords which may have an effect to us advertiser of they loose. In an article published by MercuryNews.com they have explained on how did this happen.

Google settled a lawsuit with American Blind & Wallpaper Factory on Friday, ending a long-running battle about whether its keyword-advertising policy infringed trademarks.

Eric Goldman, director of the High Tech Law Institute at Santa Clara University, said the outcome amounted to a “stunning victory” for Google.

American Blind sued Google four years ago for selling ads to its competitors that were triggered by search terms, also known as keywords, that exactly or nearly matched its brands. A verdict that found Google had infringed trademarks could have had major implications for Internet advertising.

And the best thing is they settled it and it will not affect our earnings.
