New classification for patents on additive manufacturing

To facilitate patent information searches, the Offices have introduced a new sub-class which covers additive manufacturing separate from the process or material used.

Faced with the expansion of patents relating to the techniques of additive manufacturing and the importance of these technologies for the industry, the Patents Offices have introduced subclass B33Y in the 2015.01 version of the CPC (Cooperative Patent Classification). 

B33Y

ADDITIVE MANUFACTURING, i.e. MANUFACTURING OF THREE-DIMENSIONAL [3-D] OBJECTS BY ADDITIVE DEPOSITION, ADDITIVE AGGLOMERATION OR ADDITIVE LAYERING, e.g. BY 3-D PRINTING, STEREOLITHOGRAPHY OR SELECTIVE LASER SINTERING

B33Y10/00

Processes of additive manufacturing

B33Y30/00

Apparatus for additive manufacturing; Details thereof or accessories therefor

B33Y40/00

Auxiliary operations or equipment, e.g. for material handling

B33Y50/00

Data acquisition or data processing for additive manufacturing

B33Y70/00

Materials specially adapted for additive manufacturing

B33Y80/00

Products made by additive manufacturing

B33Y99/00

Subject matter not provided for in other groups of this subclass

Even if this new classification simplifies the work of searching the patent databases, in many cases this remains specialist work requiring professional tools.
