What To Know About Supplemental Examinations

A supplemental examination is a procedural mechanism available in the United States Patent and Trademark Office (USPTO) that allows a patent owner to request a review of their own issued patent to consider, reconsider or correct information believed to be relevant to the patent. This procedure aims to enhance the integrity of the patent system by enabling the correction of potential issues in a patent before it becomes the subject of litigation or enforcement action. The purpose of a supplemental examination is to allow patent owners to address any questions about the patentability of their inventions, such as prior art or issues regarding novelty and nonobviousness, that were not adequately considered during the original examination process.

The right to request a supplemental examination is granted exclusively to patent owners. This process provides an opportunity for patent owners to proactively clarify and strengthen their patent’s validity. By utilizing supplemental examination, patent owners can make necessary corrections and adjustments to their patents, potentially forestalling future legal challenges related to the validity of the patent.

Which Patents Can Be Eligible For Supplemental Examination?

A patent owner may request supplemental examination of any patent during the period of enforceability of the patent. This means that as long as your patent is still enforceable, you can take advantage of this important USPTO procedure.

Only a patent owner may file a request for supplemental examination. The office is not authorized to permit third parties, licensees or other nonowners to file this type of request. If your patent is jointly owned, all owners must participate in the request under normal circumstances, as the USPTO requires all parties with an ownership interest to act together as a composite entity.

What Are Common Examples Of Items Of Information In A Supplemental Examination?

The supplemental examination process allows patent owners to present various types of information for consideration by the USPTO. These include:

• Prior art patents or publications that were not considered during the original examination
• Information related to patent-eligible subject matter (35 U.S.C. § 101)
• Evidence potentially affecting anticipation determinations (35 U.S.C. § 102)
• Materials relevant to obviousness considerations (35 U.S.C. § 103)
• Information concerning written description requirements
• Documentation regarding enablement issues
• Materials related to best mode considerations
• Information affecting claim indefiniteness determinations
• Declarations or affidavits presenting separate items of information

Each of these items will be carefully examined by the USPTO to determine if they raise a substantial new question of patentability.

The Supplemental Examination Process

The supplemental examination process is a significant provision under the United States patent law that allows patent owners to strengthen the legal standing of their patents. The process provides a systematic approach for patent owners to address and correct information related to their patents post-issuance.

Request For Supplemental Examination

A patent owner can initiate a supplemental examination by submitting a request to the USPTO. This request should include information that the patent owner believes to be relevant to the patent, which may include prior art or other issues affecting patentability that were not considered or were inadequately considered during the original examination. The USPTO has established specific requirements for these requests, which must be met for the process to proceed.

Conducting The Examination

Once a request that meets the necessary criteria is received, the Director of the USPTO has three months to conduct the supplemental examination. This involves a thorough review of the submitted information to determine if it raises a substantial new question of patentability (SNQP). The conclusion of this examination phase is marked by the issuance of a certificate that details whether an SNQP has been identified.

Reexamination Ordered

If the certificate indicates that one or more items of information raise an SNQP, the director will order a reexamination of the patent. This reexamination follows the procedures for ex parte reexaminations with the limited exception that the patent owner is not permitted to file a statement regarding the SNQP. The reexamination will specifically address each SNQP identified during the supplemental examination.

Legal And Regulatory Implications

The outcomes of the supplemental examination and any subsequent reexamination have significant implications for the enforceability of the patent. A patent will not be deemed unenforceable based on information that was not considered, was inadequately considered or was incorrect in a prior examination if it has been addressed in the supplemental examination. However, certain exceptions apply, particularly concerning allegations made prior to the supplemental examination request or defenses raised in certain types of litigation.

The supplemental examination process is a valuable tool for patent owners to rectify issues with their patents proactively. It provides a pathway to reinforce the validity of patents, thereby enhancing their enforceability and reducing the likelihood of successful legal challenges based on previously unconsidered information.

The outcome can significantly affect the enforceability of the patent, making it crucial for patent owners to engage knowledgeable and experienced attorneys who can navigate these complex processes effectively.

Our sophisticated understanding of both the law and technology makes us uniquely qualified to guide you through this complex process, helping you maintain the strength and enforceability of your valuable intellectual property.

Does A Supplemental Examination Immunize A Patent If Fraud Is Discovered During The Proceeding?

No, a supplemental examination does not provide immunity if actual fraud is discovered. Under 35 U.S.C. § 257(e), if the USPTO Director becomes aware during the proceeding that a material fraud on the Office may have been committed in connection with the patent, the matter will be confidentially referred to the U.S. Attorney General for criminal investigation. Supplemental examination protects against honest errors and omissions, but it cannot be used as a safe harbor to shield intentional deception or fraudulent misconduct.

Can A Third Party Participate Or Submit Observations?

No, third parties cannot participate or submit observations.

When it comes to supplemental examination proceedings, federal patent law and regulations strictly prohibit third parties from:

• Submitting papers
• Filing observations
• Participating in any manner

Pursuant to rules established by the U.S. Patent and Trademark Office (USPTO), the supplemental examination process is an ex parte proceeding reserved for the patent owner.  If a third party files observations, petitions or prior art, the USPTO will refuse to enter the submissions into the file or expunge them if entered inadvertently. Only the entity holding the entire right, title and interest in the patent may request a supplemental examination. Even if the USPTO orders a reexamination under 35 U.S.C. § 257(b), third parties have no right to file opposition papers or observations at any stage.

Third parties seeking to challenge a patent have some administrative and judicial remedies available:

1. USPTO Inter Partes Review (IPR) and Post-Grant Review (PGR): Third parties may initiate separate, contested proceedings before the Patent Trial and Appeal Board (PTAB) to challenge patent validity.
2. U.S. District Court for the District of Columbia/Federal Circuit Litigation: A third party can raise patent invalidity defense claims or plead inequitable conduct in federal district court. If an invalidity defense or allegation of inequitable conduct is formally pled in a civil action before the patent owner requests a supplemental examination, the safe harbor under 35 U.S.C. § 257(c)(2) will not protect the patent owner.
