I can see the need for two claims, one which specifies a range ( to protect against similar claims with different numbers ), and a second which specifies the precise, desired pressure. The intermediate ones are mysterious to me.
Could it be to try to "claim" multiple ranges? With the idea being that if someone finds prior art that covers one of the larger ranges, Starbucks gets to "keep" the smaller ranges?
And if so, does anyone know where we can get a good deal on pitchforks?
