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.
Patent Integration has a patent-landscaping function that can visually represent a set of tens of thousands of patents/patent applications. This allows you to convincingly show the technical positions of your company and its competitors to your management and business strategists in order to formulate management strategies and business strategies.
磁心, Changes in the Number of JP Patents/Patent Applications
The changes in the number of patent filings of 磁心 over the last 20 years (JP) are shown below.
The change in the number of patents/patent applications is the most basic index in patent analysis. By examining the change in the number of patents/patent applications, you can see the status of technological development and R&D focus for each company or technology. It should be noted that since there is a one and a half year lag between the filing and the laying open of patent applications, it is not possible to analyze the situation more recently than one and half years prior to the present.
In this report, you can only see the change in the number of patents/patent applications by company or technology, whereas Patent Integration allows you to quickly compare the number of patent applications with your competitors in each technical field by cross-referencing with other keywords and patent classifications.
Search Set (Analysis Patents)
This patent analysis report was created for a patent search set of 7,361 cases retrieved by applying the following search formula and analysis period to the following patent database. Patent information such as a patent analysis result, a patent map, and a patent landscape can be freely used for patent searches, analysis, and work on intellectual property strategies, including IP landscaping.

Please consider using it for searches for important patents/patent applications.
Glossary
- Cited
- Indicates that the patent/patent application has been cited (by Examiners) in notices of reasons for rejection in the examination process of other (Japanese, U.S., or European) patent applications. The higher the number of citations, the more important the patent/patent application is considered to be.
- Request for invalidation trial
- Indicates that a third party has requested a procedure to invalidate the patent. It is likely to affect the business of third parties and is considered to be of high importance.
- Opposition
- Indicates that a third party has filed a petition with the Patent Office to hear the validity of the patent again. Like the trial for invalidation, it is considered to be of high importance.
- Information provision
- Indicates that a third party has provided the Patent Office with useful information for examination for the patent filed. It is usually considered to be of high importance because it is done to prevent the patent from being granted.
- Browsing request
- Indicates that a third party has requested the Patent Office to view the patent bag (a set of documents exchanged between the Patent Office and the applicant). The bag is often checked prior to trial for invalidation, opposition, and provision of information, and is considered to be a highly important patent.

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.
