Patent law in Yokohama falls under the jurisdiction of the Japanese national legal system, as intellectual property rights are protected under national law. Japan follows a "first-to-file" system, meaning that the right to obtain a patent is awarded to the person who first files an application for a novel, inventive, and industrially applicable invention. The Japan Patent Office (JPO), a national government body, manages the examination and registration of patents. Although Yokohama does not have unique local patent laws, businesses and inventors operating within Yokohama must comply with the national patent laws as well as international treaties to which Japan is a signatory, such as the Paris Convention and the Patent Cooperation Treaty (PCT).
There are various situations in which individuals or businesses may require legal assistance regarding patents. If you are an inventor or entrepreneur wanting to protect your invention, a lawyer can help with drafting and filing patent applications, ensuring they meet all formal requirements. A lawyer can also provide support in case of patent infringement disputes, both in pursuing claims against infringers and defending against accusations of infringement. Moreover, a patent lawyer can offer strategic advice on licensing and transferring patent rights, as well as guidance on complex matters such as patent validity and enforceability.
The key aspects of patent law that are particularly relevant in Yokohama are consistent with national Japanese patent law. Patent rights in Japan are governed by the Patent Act. Notable features include the requirement for novelty, inventive step, and industrial applicability. Importantly, Japan provides for a six-month grace period for public disclosures made by the inventor before filing. Additionally, Japan operates a "request for examination" system where the patent application has to be actively examined at the request of the applicant within three years of filing. Japan also practices a relatively quick examination process compared to other countries' patent offices.
A patent in Japan lasts for 20 years from the filing date of the patent application, provided that maintenance fees are paid periodically.

In certain cases, such as pharmaceutical or agrochemical products that require regulatory approval, a patent term extension is possible for up to five additional years to compensate for the time taken in obtaining the approval.
