REVISION PROJECT C436- IL
ISRAEL NEW PROPOSAL
REQUEST FOR REVISION OF THE IPC (CL)
Class(es) or subclass(es): C12N , C12P
1.
Demarcation of the area to be revised: C12N 5/00, C12N 15/00, C12P 21/00
2.
Reasons for the request:
(a)
(b)
(c)
(d)
(e)
Creation of IPC places covering new technologies for which no
distinct place in the IPC exists
Clarification of wordings in order to improve consistency in classifying
or to avoid overlap with other places of the IPC
Subdivision of IPC groups having a very large file size and a very high
rate of growth of the national patent documentation
Modifications required by revision changes to the advanced level

We are prepared to elaborate it
We are not in a position to elaborate it
5. General outline, possible solutions, options, etc.:
IL read the comments from : GB, US, JP, DE, EPO
And here are the changes:
- classification C12N5/027 changed to: Interaction between peptides, cells and molecules
controlling the interaction of cells.
-
IL also add another classification that belongs to this classification.
C12N5/035- Molecule inhibitors and method of inhibiting cell adhesion.
IL add examples to show these changes.

- As proposed by the EPO
. Adhesion culture is added.
-Processes for producing polypeptides and proteins using recombinant DNA technology (e.g.,
vectors ,recombinant cells, etc.)- The right place for this classification is C12P21/ because this
classification relates to preparation of peptides or proteins.
IL disagree with GB since C12N15/63 relates to introduction of foreign genetic material
using vector. It does not relate to the production of proteins and peptides.
-
The differences between Chimeric and fusion proteins are:
Fusion protein- protein formed by expression of a hybrid gene made by combining
two gene sequences. Fusion relates to combining peptides or proteins from the same
species or from different species.
- Chimera-organism composed of two genetically distinct types of cells.
That means that chimeric relates only to different species.
Chimeric proteins will not relate to fusion of proteins from the same species.
this is the reason there should be a clear distinction between fusion and chimeric.
To show the differences between them IL add examples.
