Cooperative Patent Classification (CPC)
The Cooperative Patent Classification system replaced the ECLA system in 2013. By 2015, the USPC is also expected to be completely replaced by the CPC in an effort by the USPTO and the EPO to harmonize patent classification systems.
CPC is based on the European system called ECLA which itself was based on WIPO's IPC class structure. The chief difference between IPC and CPC is CPC is far more detailed, but they are both based on the same high-level structure.
Patents are classified with CPC codes as either "Inventive" classes or "Additional" classes (formerly called Non-Inventive). In AcclaimIP, you can query patents by Inventive, Additional or both using different field codes as shown below.
Inventive classes are displayed in Bold text in the expander rows in the search result grid and in the document details window.

Primary US Classification (PCCL)
The primary US class appears first on the patent, it is in bold text, and it is supposed to best represent the "inventive step" of the invention. To find patents that are classified by the primary class, use the PCCL field code. The primary classification is in contrast to the cross-reference (XR) classification(s).
You may hear the term "Original" or "OR" bantered around by patent examiners. This is the USPTO's internal jargon for the primary class. It is called Original because when an application is received by the USPTO the first action is to classify it (by the Classification Group--a contracted vendor). The PTO uses this "original" class to route the patent to the proper examination art unit.
Note: The CCL field code returns patents classified by either the Primary or the cross reference (XR) classes.
