Background

Classes are major divisions of technology in the U.S. Patent Classification System (USPCS). Each class is furtherdivided into smaller divisions of technology called subclasses. The USPCS currently contains approximately 440 totalclasses and 140,000 total subclasses. Copies of each patent are placed (classified) in those subclasses which have beenidentified as pertinent to the information disclosed in the patent. One, and only one, of these subclasses is designated asthe "original classification" (OR), and the remainder (if any) are designated as "cross-reference classifications" (XR). Counting patents by original classifications will ensure that each patent is counted only once. However, if a patentteaches more than one concept, e.g., table and chair, only one concept, e.g., table, will be counted. To ensure that allconcepts are counted, patents should be counted in all of their classifications.

This report counts all patent documents including utility, design, plant, and reissue patents as well as statutory inventionregistrations and defensive publications.

Part I

Part I (OR's only) considers only the original classification of each patent. If the patent record is incomplete andcontains no OR designation, the patent is counted in "dummy" class 1 or "dummy" design Class D00.

Part II

Part II (OR's + XR's, Duplicates Eliminated) looks at original and cross-reference classifications. Duplicate counts areeliminated within each class, but not among classes. For example, the same patent could be counted in Class 2 and Class4 if it contained disclosure relating to both classes. If the patent record contains no classification data, the patent iscounted in "dummy" Class 1 or "dummy" design Class D00.
