We are being sued by a sister company of ACS too! (Score 1)

Go figure! We are in the middle of a similar lawsuit with ACS (or AACC) and the website entity labtestsonline.org over trademark infringement on the mark "Lab Tests Online." We used the very, very descriptive term unknowingly on one of our websites that is used solely for selling lab tests online to the general public. Some sites linked to us using the anchor text "lab tests online" along with some other variances of this term. It seems very ridiculous to me that something like this could stand up in court. They are a non-profit company. We did not take away from their revenue since they make no revenue from that site. We immediately took down any mark closely resembling "lab tests online" even though we felt we did nothing wrong. I would like to hear others opinions on this as we are looking to beat the alleged infringement case. I've performed searches in Google and other search engines for terms relating to the "lab tests online" mark and the "scholar" mark these companies are trying to sue for ownership privileges over only to find hundreds if not thousands of cases where it is being used on sites and for products. It seems to stop the use of such broadly used terms, these companies should monitor the use of the terms more frequently. I found some companies and sites using both sets of marks back to several years ago. Comments very welcome on this... Thanks
