Case 1 - data are taken from 'A', an element known to prior art; said data are processed (a novel process) and results are useful for field 'B' to the extent that they meet part of its requirement.
Case 2 - same data are generated besides other data by 'C', an element and the process used therein are not known in prior art; said data are processed (a process different from as in Case 1 as well in any other prior art) and results are used for field 'B' to the extent that they meet all its requirement at much lower cost.
These observations are based on all parts I.e. Abstract, Drawing, Specification and Claims of applications related to case 1 and case 2.
Will element 'A' and process of Case 1 be prior art to element 'C' and process of Case 2 ?
Observation based on Indian Patent Act will be much appreciated. None the less, any generic view based on patent laws of any jurisdiction are welcome.
