Achievement in Creation of Stronger Intellectual Property -"HARAKENZO more " will protect your intellectual property making full use of our prominent research skills and accurate analysis-

image001Consistent with the recent globalization, intellectual property is increasingly considered of value as a management tool. In order to utilize intellectual property as a legally protected right, not as a know-how right, it is generally required in every country to pass several procedures, i.e., application, examination and registration to finally obtain the right. However, it is necessary to take complicated steps to obtain the right, which also comes at a high cost. Thus, from the standpoint of efficiently completing procedures and preventing extra costs, search, analysis and patent mapping play important roles.
Careful attention should be paid to competitors' application trends, and it is also necessary to make enough preparations in case of a conflict arising from an infringement of rights. It would also be possible to keep an eye on the trend of your competitors' applications through appropriate search and analysis. If a conflict occurs, a legal opinion of the right, etc. based on a thorough search and analysis will be useful. Patent mapping, which analyzes the collected information from various points of view, is useful for not only understanding past trends, but also for predicting future trends.

Further, when you develop a new product, it is very important to consider the possibility of infringement of your intellectual property by other companies at every stage, from planning the development theme to the production and sales of the final product, and to avoid these conflicts in advance.
Therefore, at various stages, before application to after patent grant, or from planning of the development theme to the production and sales of the final product, "Search, Analysis and Patent Mapping" will be necessary.
