Staging is Now a Mini Empire

There was a funny post on Curbed today about staging a house. As I read on, I see this woman, Barb Schwarz (photo right, with tree), has a Web site and she claims to be the founder of the staging concept:

Barb Schwarz has personally Staged and Sold over
3,000 homes in the greater Seattle area. Barb is the creator of the Staging Home Concept and she holds the Federally Registered Trade mark from the US Government on Stage®.

She holds the trademark for the word "staged"! Does the New York Times have to abide by this? And now, every time I write the word stage, do I need to put a registered mark on this? This is all very confusing. I need a lawyer to get through this blog.
