There is nothing wrong with [Chris' answer](https://writers.stackexchange.com/a/6696/2533), but I'd like to add two things. First, **(c)** (from the title of the question) or more accurately ©, is _copyright_, which is not used with company or service names. So you would never write _Facebook©_, although if appropriate you _may_ write _© Facebook_. Second, ® - as I am sure you are aware, but adding it for completeness, trademarks can be registered with other bodies too, particularly outside of the US. For example, in Sweden, you would register with [the Patent and Trademark Office (PRV)](http://www.prv.se/). For EU-wide protection, [the European Patent Office](http://www.epo.org/index.html) should be a good place to start. And so on.
