The existing technology of patent can be the patent technology that has been published, or the technology that has been published in other ways, such as papers, technical reports, product manuals, etc. When filing an application, the patent applicant shall submit a comparative analysis report between the technology involved and the existing technology to the Patent Office to prove the innovation and feasibility of the technology.
The existing technology of patent is very important to the process of patent examination and authorization. If the applied technology is not much different from the existing technology, the patent office is likely to refuse to authorize the technology. Therefore, before applying for a patent, the applicant needs to fully understand the existing technology to determine the feasibility and innovation of the applied technology and improve the success rate and patent value of the patent application.
