After applying for a patent, before entrusting the factory to help you produce, you must sign an entrustment contract with the other party, stipulating in writing the entrusted content, liquidated damages, ownership of intellectual property rights, product delivery methods, etc. And it is best to sign a confidentiality agreement with the other party. If you have financial support, it is recommended to consult a professional lawyer.
In addition, when delivering the design drawings, it is best to leave a bottom and keep the evidence that the manufacturer received these materials from you, so as to better safeguard their rights and interests in the event of disputes in the future.
Extended data
There are three kinds of patents: invention, utility model and design. You should choose the right patent according to your own product. For example, if you want to apply for an invention patent, you must make sure that it meets the requirements of the invention patent. Before applying for a patent, you'd better search the application database yourself to determine whether anyone has applied for a patent for this design.
Many people think that their designs are relatively small, so they don't apply for patents, which is actually an incorrect understanding. On the one hand, applying for a patent is to protect one's intellectual property rights and prevent others from copying. On the other hand, patents can be realized, and the transfer of patents can directly benefit.
