Yup, agreed. If I'm reading this correctly, key issues are:

- Pat. 5,425,085 is about a box that is connected between phone and 
phoneline and which does carrier select dialling (prefix dialling)
- Pat. 5,519,769 is about a database that holds rating information

Remember: DUNDi does not deal with either of these:
- There is no carrier select dialling
- There is no database with rating information

But unfortunately, US patent laws seem to be highly subjective to the 
judge in session. So who knows...
