CPC Definition - Subclass B82Y
This place covers:
Applications and aspects of nanostructures which are produced by any method, and is not restricted to those that are formed by manipulation of individual atoms or molecules.
- This subclass is intended to enable a comprehensive search of subject matter related to nanostructures by combination of classification symbols of this subclass with classification symbols from other subclasses. Therefore this subclass covers aspects of nanostructures that might also be entirely or partially covered elsewhere in the IPC. This subclass is for secondary classification, i.e. obligatory supplementary classification of subject matter already classified as such in other classification places.
- The classification symbols of this subclass are not listed first when assigned to patent documents.
- Note that B82Y uses the same definitions for nanosize, nanoscale and nanostructures as B82B, but that the definition of B82B is more restricted in that it relates to specific nanostructures formed by manipulation of individual atoms, molecules, or limited collections of atoms or molecules as discrete units. Documents classified in B82B should also be classified in B82Y
Attention is drawn to the following places, which may be of interest for search:
Nanocapsules for medicinal preparations | |
Langmuir-Blodgett films | |
Nanostructures formed by individual manipulation of atoms, molecules, or limited collections of atoms or molecules as discrete units; manufacture or treatment thereof | |
Preparation of carbon nanostructures, e.g. bucky-balls, nanotubes, nanocoils, nanodoughnuts or nanoonions | |
Scanning probe techniques | |
Optical quantum wells or boxes | |
Nanostructured thin magnetic films | |
Molecular beam epitaxy [MBE] | |
Quantum wire FETs |
In this place, the following terms or expressions are used with the meaning indicated:
Nanosize, nanoscale | relate to a controlled geometrical size below 100 nanometres (nm) in one or more dimensions |
Nanostructure | an entity having at least one nanosized functional component that makes physical, chemical or biological properties or effects available, which are uniquely attributable to the nanoscale |
See also subclass B82Y.
Note that this group deals with artificial structures, particles etc. Proteins and viruses as they appear in nature are to be classified in C07K 14/00, C12N 9/00 or C12N 7/00 and (viral) vectors constructed by cloning techniques are to be classified in C12N 15/00.
Although they may be of nanosize, liposomes and virus-like particles (VLPs) are not considered to be nanotechnology.
In this place, the following terms or expressions are used with the meaning indicated:
Functionalized nanotube/ nanowire | linear nanostructures with a linear extension having a diameter of the order of 100 nanometer or less and a high aspect ratio (e.g > 1000), having specific chemical groups (e.g. receptors) physically or chemically bound to their surface. |
In patent documents, the following abbreviations are often used:
CNT | Carbon Nanotubes |
SWNT | Single Wall Nanotubes |
In patent documents, the following words/expressions are often used with the meaning indicated:
"nanoparticle" | "liposome" or "virus-like particles" (VLPs). |
See subclass B82Y.
In this place, the following terms or expressions are used with the meaning indicated:
Nanowire, nanorod | nanostructure with a linear extension having a diameter of the order of 100 nanometer or less and a high aspect ratio (e.g > 1000) |
Molecular wire | molecular-scale objects with linear structure, which conduct electrical current, commonly comprising freely moving electrodes |
In patent documents, the following abbreviations are often used:
SET | Single Electron Transitor |
See subclass B82Y.
Note that this group deals with nanostructures used for sensing or actuating, wherein the nanostructure itself (e.g. quantum dot, nanotube) is at least part of the sensor or actuator. Macroscopic apparatuses used for sensing or actuating at a nanoscopic scale or resolution (like, e.g., scanning probe microscopes) are to be classified in B82Y 35/00.
In this place, the following terms or expressions are used with the meaning indicated:
Functionalized nanotube/ nanowire | linear nanostructures with a linear extension having a diameter of the order of 100 nanometer or less and a high aspect ratio (e.g > 1000), having specific chemical groups (receptors) physically or chemically bound to their surface. |
See subclass B82Y.

In patent documents, the following abbreviations are often used:
MTJ | magnetic tunnel junction |
SV | spin valve |
CPP | current-perpendicular-to-the-plane |
CIP | current-in-the-plane |
AP | antiparallel |
APC | antiparallel coupling |
APF | antiparallel free |
MR | magnetoresistive or -resistivity or -resistance |
AMR | anisotropic magnetoresistive |
GMR | giant magnetoresistive |
TMR | tunneling magnetoresistive |
SVMR | spin valve magnetoresistive |
See subclass B82Y.
In patent documents, the following abbreviations are often used:
CNT | carbon nanotubes |
SWCNT | single wall carbon nanotubes |
MWCNT | multi-wall carbon nanotubes |
SAM | self-assembled monolayer |
QD | quantum dot |
See subclass B82Y.
In patent documents, the following abbreviations are often used:
SPM | scanning probe microscope |
AFM | atomic force microscope |
See subclass B82Y.
Note that this deals with nanostructures as defined in B82Y. This means that for example documents relating to nanocomposites which are prepared using pre-made nanostructures (i.e. as bought from a supplier) will not receive B82Y 40/00, since the nanostructures themselves are not prepared or manufactured in the document.
In this place, the following terms or expressions are used with the meaning indicated:
Nanostructures | an entity having at least one nanosized functional component that makes physical, chemical or biological properties or effects available, which are uniquely attributable to the nanoscale |
In patent documents, the following abbreviations are often used:
CNT | carbon nanotubes |
SWCNT | single wall carbon nanotubes |
MWCNT | multi-wall carbon nanotubes |
SAM | self-assembled monolayer |
QD | quantum dot |
See subclass B82Y.
Documents are preferably not classified here. Therefore, all other groups take precedence.
