After the battle for personnel between Xiehe Hospital and 301, Yang Ping started to focus on developing the external fixator for treating scoliosis.
Yang Ping had now mastered the skill of writing patent applications. When he had worked on the device for reconstructing children's crossed ligaments, he had engaged several agencies to do the writing.
However, these engineers didn't quite understand Yang Ping's device, they kept missing the point. Without catching the key points, the intellectual property couldn't be effectively protected and could easily be circumvented by others.
Yang Ping had no choice but to take matters into his own hands. He wrote the patent application himself and handed it over to the agency to assist with the application.
Since then, Yang Ping had realized the importance of writing patent applications and dedicated time to studying how to write them.
