According to the 2023 edition of the “Guidelines for Patent Examination”, the requirements for the word count of invention patent names have been revised. The revised regulations are as follows: generally, it should not exceed 25 words, and if necessary, it may not be subject to this limit, but it should not exceed 60 words. (The original clause was: generally not exceeding 25 words, but in special circumstances, such as certain inventions in the field of chemistry, up to 40 words may be allowed)

It can be seen that this modification has increased the maximum word count of the invention name (from 40 words to 60 words).

Secondly, in special circumstances, due to their professionalism and complexity, patent names may need to contain more information to accurately describe the content of the invention. Therefore, for this type of patent, the word count is not limited to 25 words. However, even so, it is still necessary to meet certain conditions, such as ensuring the accuracy and clarity of the patent name, and avoiding ambiguity. This regulation is mainly based on considerations of easy identification, memory, and management, while also maintaining the simplicity and clarity of patent names.

Overall, the word limit for patent names is an important provision in patent regulations, and applicants should strictly comply with it when applying for a patent. At the same time, for patents in special fields, it is also necessary to reasonably determine the word count of the patent name under specific conditions. This not only ensures the accuracy and conciseness of patent names, but also helps improve the efficiency and management level of patent examination.
