DEFINITION

Classification: 930/10

PEPTIDE OR PROTEIN SEQUENCE:

Cross-reference art collection for a peptide or protein consisting of an identifiable sequence of at least four amino acids covalently bound through at least one normal peptide link into a backbone structure.

(1) Note. It should be noted that the patents included in this and the indented art collections 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 four or more amino acids from the insulin structure are shown in the patent, the patent is not included in these art collections.

(2) Note. Rules of placement in Cross-Reference Art Collections 10-320: A compound is placed in ALL art collections, regardless of hierarchy, where the definition concepts include the compound in question, unless an art collection note excludes a compound from one art collection after it has been placed in another. Therefore, Class 930 provides a way of narrowing or fine-tuning computer searches by the use of Boolean operators. As an example, art collection 21 (D-amino acid) can be connected with art collection 70 (corticotropin) by using "and" in order to get a listing of patents which may include corticotropin sequences containing D-amino acids. One may alternatively use "not" and get a list of the patents with corticotropin sequences containing no D-amino acids. As another example, one may use "and" between art collection 22 (radioactive atom) and art collection 60 (calcitonin) in order to get a list of patents which may include radioactive calcitonin.

(3) Note. Patents are placed in this and the indented art collections according to the amino acid sequence or sequences disclosed in the patent. In many cases these sequences may not be part of the claimed subject matter but are disclosed in other parts of the patent.

(4) Note. In many of the indented art collections the terminology "related peptides" is used. Such a peptide can be one whose structure corresponds to at least half the amino acid residues of the named peptide, or one which is the product of side chain substitution, C or N terminal chain extension and insertion, or a replacement reaction, or a removal reaction. "Related peptides" also encompasses functional analogues of the named compound. Such analogues

may also be placed in any of the other appropriate art collections.
