How many words does it take to write a patent application?

The number of words required for a patent application generally does not exceed 30,000 words, including 25,000 words for invention patents and 8,000 words for utility model patents and design patents. It should also be noted that the number of words in a patent application is not strict, and the number of words depends on the content and complexity of the application. On the premise of ensuring that the application is complete, clear and accurate, the fewer words, the better.
