Introduction
The concept of the "IP landscape" (IPL) has been attracting attention recently.
An IP landscape is not limited to patent information, but also integrates and analyzes business information (e.g., non-patent information such as papers, news releases, stock information, and market information). Intellectual-property-based business management is realized through the analysis of intellectual property information applied to the formulation of management strategies and business strategies. This is a comprehensive approach that includes but not limited to planning of open and closed strategies, selecting M&A candidates, searching for alliance partners, and formulating intellectual property strategies, through the exploitation of intellectual property information.
IP landscaping usually includes patent search and patent analysis. In patent search and patent analysis, it is important to grasp the market position of each company and the overall technological trends and development trends for each technology. More specifically, it is important to understand what intellectual property your own company and other companies hold, what the strengths and weaknesses of other companies are, and how other companies are trying to exploit their intellectual property. In other words, it is important to understand both the business strategy and the intellectual property strategy of each company.
After reading this search report, you may be interested in more detailed patent searches and patent analysis. We offer a service called Patent Integration, which is an integrated patent search and patent analysis service. With reasonable pricing and a simple user interface such that even beginners can quickly search for and analyze patent information by company or technology from a web browser, please consider using it for detailed patent searches, patent analysis, and IP landscaping.

Please note the following points for use.
e-Patent will not be liable for any damages or losses arising from the use of the global patent application status, ranking information, or population search formula in the "SDGs Global Company Ranking from a Patent Perspective". Items with ● in front of the target are not supported at this time (judged to be difficult to approach from the patent information analysis).

There is no problem to cite patent application status and ranking information, but please clearly indicate "Source: e-Patent Co.
Graphs are image data.
Please note that the various graphs are image data, but we cannot provide them in text data.Scope of coverage for each goal/target
- Based on the description of each goal and target of the SDGs, we have set the scope of technologies to be covered based on our and e-Patent's past experience, etc. (in some cases, the search is based on social issues themselves). Therefore, please note that there is a possibility that this "SDGs Global Company Ranking from Patent Perspective" may not cover 100%.
- A population search formula is clearly indicated for each goal/target (database: Patent Integration). You may use the population search formula as it is, or you may improve it by yourself.
- This search covers patents and utility models, including both published and registered patents (design and design patents are excluded). The unit of count is the number of applications, not the number of patent families.
About the name collation and name control of applicants and right holders
- Company rankings are based on the results calculated by "Patent Integration", with Japanese organizations in Japanese and other companies in English (some are in Japanese).
- Company names may be the names of the companies at the time of application, but the results calculated by Patent Integration are used as is. Company names are used as they were at the time of application.
- Because of the fluctuation in the names of companies (i.e., applicant/right holder names in the patent information), there are cases where the same company appears more than once in the top 10. The number of applications filed by the same company in the top 10 is the total number of applications filed by the company.
