As one of the most innovative and technologically advanced countries in the world, Japan's patent system plays an important role in supporting and protecting innovation. Here are some basics about obtaining a patent in Japan:

* Patent types: Japan’s patent system includes invention patents, utility model patents and design patents. Invention patents mainly protect the innovation and progress of inventions, utility model patents protect practical innovations such as the shape and structure of products, and design patents focus on the uniqueness of a product's appearance.

* Patent application process: The process of applying for a patent usually includes steps such as application submission, review, announcement and authorization. When submitting an application, the applicant needs to provide detailed patent documents, including description, claims, abstract, etc. During the review process, the Patent Office will evaluate whether the application meets the conditions stipulated in the patent law.

* Examination standards: In order to obtain patent rights, applicants need to prove that they have created innovative, non-obvious, and implementable technology or designs. During the review process, the Patent Office will search and compare prior technologies (previous patents, documents, etc.) to ensure that the content of the new application is original.

* Patent duration: Generally speaking, the validity period of invention patents is 20 years, utility model patents are 10 years, and design patents are 15 years. During this period, the patentee can initiate legal proceedings against others for unauthorized manufacturing, use, sales, etc.

* International Patent Cooperation: In order to facilitate obtaining patents in multiple countries, applicants can apply for international patents through the International Patent Cooperation System (PCT System). This makes it easier to apply for patents in different countries.

* The importance of patent protection: Patent protection helps encourage innovation, protect the intellectual property rights of inventors and companies, and promote scientific and technological development. In Japan, companies usually use patents as an important means to improve competitiveness and prevent infringement.

Overall, understanding the basics of patent acquisition in Japan is critical for innovators and businesses to succeed in this high-tech society. Through rational use of the patent system, innovation achievements can be protected and scientific and technological innovation and economic development can be promoted.
