<human>: Hi, I'm a network admin for a small company who resells software, and offers services using some of the software we sell.  One of my duties is maintenance of the company's website.

I often run into an issue with the people asking me to create/change pages that they want (c) (r) (tm) to follow every mention of any name that doesn't belong to us.  In my research, it *seems* that use of these symbols is entirely optional. (as long as they are properly registered and qualify for use of course)

Can someone point me to a resource that explains when it is appropriate, required, and/or polite to use these symbols?  I don't want our webpages covered in hundreds of these symbols out of some strange paranoia that we're legally required to use them.  Thanks!

Can you succinctly summarize the text in 1-3 sentences?
<bot>: What is the proper usage (both legal and 'polite') of these symbols when creating webpages mentioning companies and products you do not own?
