Hi Bruce,
This is the definition :
| Quote: | esp@cenet® and the IPC Reform IPC8
From the beginning of January 2006 the new International Patent Classification (version  will be in force. This will mean that there will be new, more powerful and focussed possibilities of searching patent documents.
esp@cenet users who are already familiar with ECLA will readily see that there are concepts and practices common to the new IPC8
The following is a simple description of how the IPC8 affects esp@cenet users. For more detailed information about IPC 8 please see: http://ipc-reform.european-patent-office.org/index.en.php
In simple terms the new IPC 8 classifications come in 4 "flavours":
* Core level
* Advanced level
* Invention information
* Non-Invention information - sometimes called "Additional Information.
You will see "Non invention information" and "additional information" used interchangeably here and in other articles about the IPC8.
The Core Level may be thought of as a relatively low resolution, static, classification level. It will be revised on a three yearly cycle.
The Advanced Level can be considered as a high resolution, dynamic classification scheme that will be reviewed on a three month time-scale.
Invention Information is that which appears in the claims of the patent application - and will be classified according to core and/or advanced level IPC 8
Additional (non-invention) information appears in sections other than the claims, and can be prior art cited, or other kinds of explanations or historical information mentioned by the applicant. All of this additional information can be classified according to the IPC8 core or advanced level.
The following matrix representation may help you in visualising the 4 aspects of the IPC8:
............................................Core level.........Advanced level
Invention.............................eg. A61L2/02........eg. A61L2/025
Non Invention
(additional information).........eg. A61L2/02........eg. A61L2/025
Under the new IPC8 documents will be classified according to combinations of core level and/or advanced level classification symbols applied to the invention and/or the additional information disclosed.
IPC8 search in esp@cenet
The advanced search mask will not change, that is to say the two separate fields of IPC and ECLA will remain.
The different IPC8 "flavours" can be selected by means of search modifiers within the IPC search field.
* ci: selects IPC Core Invention
* cn: selects IPC Core Non Invention
* ai: selects IPC Advanced Invention
* an: selects IPC Advanced Non Invention
* c: selects IPC Core
* a: selects IPC Advanced
example of the search syntax:
ci:G11B5/62 |
