Ownership changes, company mergers, company address changes, and other changes involving applicants, inventors, etc., will have a direct or indirect impact on the company and its assets during the patent application process. It is relatively complicated and error-prone. In reality, many patent applicants/patentees do not understand how to make the changes and are not very clear about the requirements for documents and fees required for changes, resulting in unnecessary corrections and delays in patent applications/patent process, even resulting in the loss of rights.
