Increased employee mobility, health challenges, and the economic downturn due to the COVID-19 pandemic may result in more inventors than usual being unavailable to sign declarations for patent applications as required by the U.S. Patent and Trademark Office (USPTO) for all applications. In other cases, inventors may have a falling out with employers or refuse to cooperate in signing declarations. If patent applicants cannot acquire declarations from these unavailable or uncooperative inventors, significant difficulties may arise in patent prosecution, such as delayed issuance or application abandonment. Fortunately, the USPTO provides for applicant control of patent prosecution by filing a substitute statement in the event a declaration cannot be obtained. This article summarizes the requirements of substitute statements and identifies pitfalls to avoid in preparing and filing substitute statements.
Substitute Statements
Applicants have the option of filing a substitute statement for unavailable inventors listed in applications filed on or after September 16, 2012. A substitute statement may be submitted where an inventor is deceased, is legally incapacitated, cannot be found or reached after diligent effort, or refuses to execute a declaration. 35 U.S.C. § 115(d).
In cases where an inventor refuses to execute or cannot be found after diligent effort, the substitute statement may only be filed if the applicant is an assignee, an inventor on the same application, a party to whom the inventor is under an obligation to assign, or a party who otherwise has sufficient proprietary interest. MPEP § 409.02, MPEP § 409.05.
In cases where the inventor is deceased or legally incapacitated, the substitute statement may only be filed if the applicant is an assignee, a legal representative, a party to whom the inventor is under an obligation to assign, or a party who has sufficient proprietary interest. If a legal representative of the inventor exists, then the applicant is not required to involve the legal representative. MPEP § 409.01(a).
A substitute statement must be filed before paying the issue fee or as otherwise outlined in the Notice of Allowability. For national stage applications, the applicant must file the substitute statement no later than the filing of a Request for Continued Examination (RCE).
Substitute Statement Requirements
In addition to complying with the requirements of 35 U.S.C. § 115(b), the executor of the substitute statement must: 1) identify the person executing the substitute statement and the relationship to the non-signing inventor; 2) identify the basis for which a substitute statement is required; 3) acknowledge the penalties clause under 37 C.F.R. 64(e); 4) identify the inventor to whom the statement applies; 5) review and understand the contents of the application (including the claims); and 6) be aware of the duty to disclose to the USPTO all information known to the person to be material to patentability as defined in 37 C.F.R. 1.56.
Additionally, the legal name of each inventor is required in the substitute statement if not already provided in an Application Data Sheet (ADS). The last known mailing address and the residence of both the executor of the substitute statement and the non-signing inventor (unless deceased or legally incapacitated) are required if not already provided in the ADS.
If a substitute statement is required on the basis that the inventor cannot be reached with diligent efforts, the USPTO may require that evidence be provided showing why the inventor is unavailable and the efforts made to contact the inventor. Remember to document all attempts to have the inventor sign the declaration in the event that the USPTO requests evidence submission after the filing of a substitute statement. Examples of such documentation are sent emails, U.S. mail return receipts, mail tracking number receipts, and mail tracking provided online by the mail service used to mail declaration information to an inventor.
Substitute Statement Alternatives
A signed assignment may serve as a declaration if the assignment includes the information and statements required in 37 C.F.R. 1.63(a) and if a copy of the assignment is recorded in the USPTO's assignment database. A copy of an inventor's declaration from a prior application in a benefit chain may also serve as a declaration for the unavailable inventor if the declaration meets all required declaration requirements. A prior declaration may be insufficient if, for example, the prior declaration is for an application subject to pre-AIA rules and the instant application is subject to post-AIA rules, which have different declaration language requirements than pre-AIA rules.
Final Considerations
Patent applicants can gain control over patent prosecution and assert patent rights by filing a substitute statement. Before filing a substitute statement, applicants should coordinate with patent counsel regarding their particular circumstances and should consult current USPTO rules.
