That’s correct. The best example is that of cellophane tape which was a brand but it lost protection. Xerox very aggressive in the day and wrote lawyer letters to anyone who used Xerox as a verb to protect their brand. I’m not sure if Google has ever done similar but people use google as a verb to mean web search and I’m not sure if they worried about losing brand protection or though of it as an advantage in acquiring users.
