Patentability Report Not Obligatory
Note:
A Patentability Report is not required but may be used if it saves examiner time or improves quality due to specialized knowledge.

The above outlined Patentability Report practice is not obligatory and should be resorted to only where it will save total examiner time or result in improved quality of action due to specialized knowledge. A saving of total examiner time that is required to give a complete examination of an application is of primary importance. Patentability Report practice is based on the proposition that when plural, indivisible inventions are claimed, in some instances either less time is required for examination, or the results are of better quality, when specialists on each character of the claimed invention treat the claims directed to their specialty. However, in many instances a single examiner can give a complete examination of as good quality on all claims, and in less total examiner time than would be consumed by the use of the Patentability Report practice.
