Class Information
Number: 930
Name: Peptide or protein sequence >
Description: Class 930 consists of two wholly separable parts, cross -reference art collections 10-320 and digests 500-822. This class is intended to be used as a searching area for patents which disclose an identifiable peptide or protein sequence derived from at least four specified named amino acids. Rules of placement into these areas vary, and although any search in this class is optional, searching Class 930 is useful.
