Some industry standard texts should not be messed with like: "This lawnmower is not designed to trim hedges." :)
A single sentence of that type should not (theoretically) cause a duplicate content. However, given the increasing REDUNDANCY of content found across the web, it might be a factor where the SEs arbitrarily pick and choose which sites appear for any query. (10,000 sites, 10 top spots minus whatever big brands appear first...) That's a pretty small target to get listed.
