The argument a TM holder could have used, potentially, is that it's a "sham" site, i.e. essentially "made for advertising", instead of a legit news site.
Although, in this particular case, the principals behind the site appear to have some legitimacy. See:

(i.e. doctors with medical background, others with publishing background)
If it was just an Average Joe doing it, or the typical "scraper" "made for Adsense" site, the drug company probably would not settle.
