What is a “cross-reference art collection” in patent searching?
A “cross-reference art collection” in patent searching refers to a grouping of patent documents that are relevant to a particular subject matter but do not fit neatly into a single classification. The MPEP 904.02(a) states:
“Cross-reference art collections, if any, associated with the class or subclass are also included in the search (MPEP § 903.07).”
These collections allow examiners to find relevant prior art that may be classified in multiple areas, enhancing the thoroughness of the search process. When conducting a classified search, it’s important to consider these cross-reference collections to ensure a comprehensive review of potential prior art.
