Paper isn't a company name. IANAL either but I believe there is a distinction in Trademarks between company and product names.

There are over 2,000 records that include various forms of the word "target". Over 3,000 for "apple". Over 3,000 for "windows".
If you use a common word in a trademark you may be able to prevent others from using it for the exact same (or very similar) product, but you don't own the word outright.
Facebook might well be okay with a camera app called Target (though they might not be -- someone else may be using it for that purpose already). They would definitely be in trouble if they started a department store called "Facebook Target", though.
