is ranging from

I'm not familiar with patentese. However, I find "is ranging from" very odd and would have thought it should read "ranges from". I find "ranges from" just as natural as Tony's "the value lies between ...", but, unlike the latter expression, it unambiguously includes the upper and lower figures.

I think it's simply because 'est compris entre... et...' is a peculiarly FR expression that does not have a natural equivalent in EN.
The oddity here, however, would appear to be the use of 'is ranging from...' — but that seems to be something specific to patents, and I guess stems from the way the claims are express using 'is...'; in natural EN, we might more normally say "the value lies between...", but it's more awkward to make that work if you try to stick to using 'is'.
