Peptide or protein sequence

SECTION I - CLASS DEFINITION

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.

It should be noted that the patents in art collections 10-320 must contain an actual amino acid sequence. A patent containing a reference, in name only, to a peptide or protein compound with a known structure is not included. For example, though the amino acid sequence of insulin is well-known, unless a sequence of at least four amino acids from the insulin structure is shown in the patent, it is not included in these art collections.

The following steps pertain to placement and search.

(1) Compounds containing a modified or unusual amino acid (art collections 20 -25) are placed in all appropriate art collections.
