Patent and trademark assignments show record title of a patent or trademark registration. Record title is important to show ownership of intellectural property and to prevent fraud in the transfer or licensing of intellectual property. Although corporations can be patent applicants, very frequently individual inventors are the applicants who transfer ownership to employers or to third parties. Such transfers are by written assignments that are recorded in the USPTO. In trademarks, the user or intended user of a mark is the applicant. Unlike patents, intent-to-use trademark applications cannot be assigned. Since assignments are contracts, the documents should be prepared by lawyers. While forms for assignments may be found online, there are many considerations for the content of an assignment and so assignments should be prepared or reviewed by a lawyer.
