Interesting. So if let's say newRPL or the 43S projects use the dot to enter fractions HP would have a patent claim?

Don't be afraid. Patents don't live forever. In fact, they die after 18 years in Europe, IIRC. I'd guess US American rules are similar. After that lifetime, it's simply state of the art.
