An interesting example in this regard is an international patent application with the title “AI device, laser radar device, and wind farm control system.” This patent discloses an artificial intelligence (AI) device that includes a learning device and a control device. The learning device uses machine learning to analyze wind vectors and predict the power generated by a wind turbine. It compares the predicted value with the actual measured value and, if the difference exceeds a certain threshold, selects a laser radar device to measure the wind vector and obtain a measurement parameter. The control device then transmits this parameter to the laser radar device.

A thorough review of the patent claims of this Japanese patent application filed by MITSUBISHI ELECTRIC CORPORATION reveals that the main claim covers a new system that combines advanced machine learning and laser radar (LIDAR) technology to get the most out of wind energy output. The parts and functions of this invention include various elements, like a Learning Device that looks at wind vectors using machine learning algorithms.

As may be seen, while writing patent applications for Japan, drafting good patent claims, particularly for complicated technology, requires a deliberate and precise approach. Begin with broad claims to cover the fundamental parts, then use dependent claims for more specificity and detail. Avoid ambiguity by using clear, precise language and regularly defining technical words. Clearly describe each component of the invention and how they interact to communicate the invention’s full value. To enhance patent strength and enforceability, it’s essential to draft claims that address future technological developments while illustrating the novelty and inventiveness of the invention. For the same reasons, patent attorneys clearly define what sets your invention apart from prior art, emphasizing its innovation and non-obvious nature. By reviewing precedents and guidelines from relevant patent offices, the patent writers ensure that the patent claims align with current standards as defined by the Japan Patent Office. In the detailed description section of the patent application, it always helps to include examples to demonstrate the invention’s scope and working for the understanding of a reader who is skilled in the art of the technology field of the invention. Therefore, multiple review rounds with experts in both technology and patent law are crucial to finalize the contents of the patent application. At the end of the review, the goal is to confirm that your patent claims meet the legal requirements of the Japan patent office. In terms of patent writing style in Japan, drafting patents demands explicit language and detailed technical descriptions that are in line with the best practices followed by other patent offices like USPTO, EPO, UKIPO and even WIPO for PCT patent applications. The Japanese Patent Office (JPO) requires clarity in both technical descriptions and claims.
