According to news reports, Consim India Pvt. Ltd, a Chennai-based entity which owns bharatmatrimony.com has sued Google.com for infringement of its trademark by showing search results of its competitors through the search provided on bharatmatrimony.com. According to Consim, the search using Google on the site throws up results of its competitors such as shaadi.com or simplemarry.com, which is an infringement of its trademark.
Another news report states that as part of the search results, sponsored competitive advertisements appear, which Consim India has issues with. According to Consim, a Google search from its site (bharatmatrimony) must show results exclusively that of bharatmatrimony. A few are of the opinion that unless an exclusivity clause is part of the agreement between Google and Consim, the former cannot be sued for infringement. Google is yet to comment on this officially.
This is an interesting issue, watch out this space for more news on this dispute.
