Enablement Requirement for Biological Material
Note:
The application must disclose sufficient information to enable a person skilled in the art to make and use the invention without access to specific biological material.

Under 37 CFR 1.809(a), once the examiner has determined that access to a biological material is necessary, and there is no information that would support the conclusion that access is currently available in accordance with these regulations, the examiner should make an appropriate rejection under 35 U.S.C. 112 until such time as a deposit in accordance with these regulations is actually made or a written assurance is received in the patent application that such a deposit will be made upon an indication of allowability of the application. The examiner should clearly indicate the statutory basis for the rejection and the reasons that are relied upon by the examiner to conclude that the application does not comply with some requirement of 35 U.S.C. 112. Although not exhaustive, the following grounds of rejection may be applicable in appropriate circumstances (A) 35 U.S.C. 112(a), enablement requirement. Rejection for lack of an enabling disclosure without access to a specific biological material. This ground of rejection should be accompanied by evidence of scientific reasoning to support the conclusion that a person skilled in the art could not make or use the invention defined in and commensurate with the claims without access to the specific biological material. See MPEP § 2164.06(a).

Under 37 CFR 1.809(a), once the examiner has determined that access to a biological material is necessary, and there is no information that would support the conclusion that access is currently available in accordance with these regulations, the examiner should make an appropriate rejection under 35 U.S.C. 112 until such time as a deposit in accordance with these regulations is actually made or a written assurance is received in the patent application that such a deposit will be made upon an indication of allowability of the application.

Although not exhaustive, the following grounds of rejection may be applicable in appropriate circumstances:

A rejection for lack of a best mode will be rare in the ex parte examination process because it requires (1) a finding by the examiner that, at the time the application was filed, the inventor(s) knew of a specific material that was considered by the inventor(s) to be better than any other, and (2) if a best mode was contemplated at that time, that the inventor(s) concealed the best mode (accidentally or intentionally) by failing to adequately describe that best mode.

Under 37 CFR 1.809(a), once the examiner has determined that access to a biological material is necessary, and there is no information that would support the conclusion that access is currently available in accordance with these regulations, the examiner should make an appropriate rejection under 35 U.S.C. 112 until such time as a deposit in accordance with these regulations is actually made or a written assurance is received in the patent application that such a deposit will be made upon an indication of allowability of the application. The examiner should clearly indicate the statutory basis for the rejection and the reasons that are relied upon by the examiner to conclude that the application does not comply with some requirement of 35 U.S.C. 112. Although not exhaustive, the following grounds of rejection may be applicable in appropriate circumstances:
  • (A) 35 U.S.C. 112(a), enablement requirement. Rejection for lack of an enabling disclosure without access to a specific biological material. This ground of rejection should be accompanied by evidence of scientific reasoning to support the conclusion that a person skilled in the art could not make or use the invention defined in and commensurate with the claims without access to the specific biological material. See MPEP § 2164.06(a).
  • (B) 35 U.S.C. 112(a), written description requirement. A rejection for lack of written description typically arises in the context that the application as filed does not contain a description to support an amendment to the specification or claims, although it can arise in the context of original claims.

  • (D) 35 U.S.C. 112(b), requirement to particularly point out and distinctly claim invention. A rejection for indefiniteness, as applied to a deposit issue, requires the examiner to provide reasons why the terms in the claims and/or scope of the invention are unclear because of an incomplete or inaccurate description or the absence of a reference to a biological material.
  • (E) 35 U.S.C. 112(b), requirement to claim what the inventor or a joint inventor regards as the invention. A rejection on the basis that the claims do not set forth the subject matter that the inventor or a joint inventor regards as the invention requires the citation of some evidence, not contained in the application as filed, to support the rejection.
