Deceptive intent
From Patentbarquestions
Q) Investigating Deceptive Intent
“I had a question asking about what situation does the PTO still investigate violotations of 37 CFR 1.56.
I think the answer is in MPEP 1448″
- 1448 FRAUD, INEQUITABLE CONDUCT, OR DUTY OF DISCLOSURE ISSUES
- The Office no longer investigates and rejects reissue applications under 37 CFR 1.56. The Office will not comment
- upon duty of disclosure issues which are brought to the attention of the Office in reissue applications except to
- note in the application, in appropriate circumstances, that such issues are no longer considered by the Office
- during its examination of patent applications.
- …Form paragraph 14.21.09 should be used where the examiner becomes aware of a judicial determination of fraud,
- inequitable conduct or violation of the duty of disclosure on the part of the applicant independently of the record
- of the case, i.e., the examiner has external knowledge of the judicial determination. Form paragraph 14.22 should be
- used where, in the application record, there is (a) an explicit, unequivocal admission by applicant of fraud,
- inequitable conduct or violation of the duty of disclosure which is not subject to other interpretation, or (b)
- information as to a judicial determination of fraud, inequitable conduct or violation of the duty of disclosure on
- the part of the applicant. External information which the examiner believes to be an admission by applicant should
- never be used by the examiner, and such external information should never be made of record in the reissue application.
