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.

You can quickly extract important patents from a patent set that includes multiple competitors by cross-referencing with other keywords and patent classifications. Please consider using it for searches for important patents/patent applications.

Search for Information on Important Patents

You can quickly search for important patents/patent applications, such as patents/patent applications that were cited many times and patents that have had invalidation trials demanded against them many times.

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.
