Hello! If someone in your company can write a patent, you can also write it yourself and submit it. However, there is a big difference between writing a patent and writing a disclosure. If it is written incorrectly, it is very likely that an examination opinion will be issued, and if the response to the examination opinion is not good, the patent will not be approved. It costs time and money. Or you can learn how to write a patent from an agent. It is better to find a professional to do it. After all, the cost is not very high. Also saves time.
