A61K - Cooperative Patent Classification

CPC - A61K - 2013.07 - page 68
classification is also made according to the nature of this modifying
agent, e.g. a microparticle modified on its surface by a peptide is
classified in A61K 49/0091 and A61K 49/0056
A61K 49/0093 . . . . . . { Nanoparticle, nanocapsule, nanobubble, nanosphere, nanobead, i.e.
having a size or diameter smaller than 1 micrometer, e.g. polymeric
nanoparticle }
A61K 49/0095 . . . . . . . { Nanotubes }
A61K 49/0097 . . . . { Cells, viruses, ghosts, red blood cells, viral vectors, used for imaging or
diagnosis in vivo }
A61K 49/04 . X-ray contrast preparations
NOTE
-
In the preparation of new organic compounds and their use in X-ray contrast
preparations, classification is only made in the relevant subclasses C07C to
C07J according to the type of compound
A61K 49/0404 . . { containing barium sulfate }
A61K 49/0409 . . { Physical forms of mixtures of two different X-ray contrast-enhancing agents,
containing at least one X-ray contrast-enhancing agent which is not a halogenated
organic compound }
A61K 49/0414 . . . { Particles, beads, capsules or spheres }
A61K 49/0419 . . . . { Microparticles, microbeads, microcapsules, microspheres, i.e. having a size
or diameter higher or equal to 1 micrometer }
