The owners of the KAMA SUTRA mark are suing a competitor using the mark KAMA SUTRA CLOSET (Kamsult v Kama Sutra Closet, 13cv07403, CD Cal). However I can’t upload the complaint to DocStoc. If I had to guess why, I would suspect the presence of the words KAMA SUTRA in the complaint, and the fact that DocStoc uses content filters.
