How does the best mode requirement relate to biological deposits in patent applications?
The best mode requirement, as it relates to biological deposits in patent applications, is based on 35 U.S.C. 112(a). According to MPEP 2411.01:
“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.”
In the context of biological deposits, this means that if the inventor knows of a specific biological material that is the best for carrying out the invention, they must disclose it. If a deposit is necessary to satisfy this requirement and the best mode is not adequately described or deposited, it could potentially lead to a rejection under 35 U.S.C. 112(a) for failure to disclose the best mode. However, as noted in the MPEP, such rejections are rare in the examination process due to the difficulty in proving the inventor’s knowledge and intent.
