ANSI Standards

I have a few questions. First of all I am at a new company and I was glancing at their drawing template and a few things popped up.

First the proprietary not is located in the title block but not boxed in. Doesn't it need to be enclosed?

Second The copyright symbol is wrong the have a "c" with a circle around it. Easy fix to just put ALT+0169 but is that a big deal?

Third in the title block they have .X ± .08 does the values have to be the same  .X ± .X  and .XX ± .XX and so on?

Just a few odd questions that probably get overlooked. Let me know
