How to file a substitute specification
3 Required Parts of the Submissions
- Marked-up copy with markings showing all the changes relative to the immediate prior version of the specification of record
- Clean copy (without markings)
- Signed statement that the substitute specification contains no new matter
The ENTIRE specification is required for the marked-up and clean copies, not just the amended portion.
Marked up vs. clean copy
Marked up copy:
- A version that shows ALL changes to the most recent specification of record with markings.
- Additions of text are underlined.
- Deletions of text are shown by strike-through, except double brackets
- A version that includes ALL changes to the most recent specification of record without markings.
Drawings: Required if necessary to understand the subject matter to be patented
- A drawing necessary to understand the invention cannot be introduced after the filing date.
Common mistakes found during OPAP drawing review:
- Line quality that is too light to be reproduced
- Missing lead lines
- Excessive text or text that is not in English
- Paper format
- Incorrectly labeled figures
- Photographs that are illegible after scanning
