| Note: Subclasses 707/600-831 were established as a result of the reclassification of 707/1-206 in January 2010. Documents from abolished subclasses 707/1-206 are in the process of being reclassified. Documents from 707/1-206 have been temporarily transferred to cross-reference art collections (XRACs) 707/999.001-999.206, pending completion of the reclassification of all documents in the abolished subclasses. | ||

| E-SUBCLASSES | ||
| The following subclasses beginning with the letter E are E-subclasses. Each E-subclass corresponds in scope to a classification in a foreign classification system, for example, the European Classification system (ECLA). The foreign classification equivalent to an E-subclass is identified in the subclass definition. In addition to US documents classified in E-subclasses by US examiners, documents are regularly classified in E-subclasses according to the classification practices of any foreign Offices identified in parentheses at the end of the title. For example, "(EPO)" at the end of a title indicates both European and US patent documents, as classified by the EPO, are regularly added to the subclass. E-subclasses may contain subject matter outside the scope of this class.Consult their definitions, or the documents themselves to clarify or interpret titles. |
