Patent Proofreading Best Practices

Since the USPTO does not provide applicants with a copy of the patent text before final printing, errors in the published patent are typically flagged using a Certificate of Correction appended to the published patent. Here are the patent proofreading best practices we have developed and follow: 

  1. Ensure review of Examiner amendments.
  2. Identify PTO errors introduced by transliteration of the IFW version of patent claims and descriptions.
  3. Identify applicant errors, particularly those that are (unintentionally) introduced while complying with office actions.
  4. Identify and fix antecedent basis errors in claims.
  5. Include suggestions for remedying/correcting errors if applicable. In cases where we identify an issue that is not a clear error, flag it with an explanation of potential error.
  6. Identify whether the Continuity and Bibliographic information of the patent contains errors or inconsistencies.
  7. Provide an EFS-ready form to the client based on USPTO guidelines for the issuance of a Certificate of Correction.
