octimine has adopted the patent classification system developed by Fraunhofer ISI, the Observatoire des Sciences et des Technologies and the French patent office (INPI), based on the codes of the International Patent Classification (IPC).

The system is made up of 5 Main Areas (Electrical Engineering, Instruments, Chemistry, Mechanical Engineering, Consumer Goods and other Fields). Each Main Area comprises various subareas.

According to this model, users can narrow their search by selecting the specific areas where the patent number or technological text is more likely to be found in. The logic behind this is, that one word such as “cell”, may have many meanings: the basic structural unit of living matter, the part containing the electrode in an electrical battery, etc. Hence, the word cell has a different meaning in biochemistry and mechanical engineering. Therefore, depending on the category the word belongs to, it will be given a different weight.

Note, since a precise classification is sometimes very tricky, the algorithm has nevertheless been intelligently designed to retrieve high quality results when selecting all of the main areas. So, if you are not sure where the text should be classified, we recommend you to simple select all of them.
