What is the relationship between trade secrets and the best mode requirement?
The best mode requirement in patent law can potentially conflict with an inventor’s desire to maintain trade secrets. As explained in MPEP 2165:
“The best mode requirement creates a statutory bargained-for-exchange by which a patentee obtains the right to exclude others from practicing the claimed invention for a certain time period, and the public receives knowledge of the preferred embodiments for practicing the claimed invention.”
This means that inventors must disclose their preferred way of implementing the invention, even if it involves revealing trade secrets. However, the disclosure only needs to cover the best mode related to the claimed invention. Aspects of the invention that are not claimed and not necessary for enablement may still be kept as trade secrets.
It’s important to note that after the America Invents Act, the consequences of not disclosing the best mode have been reduced, potentially allowing inventors more flexibility in balancing patent protection and trade secret preservation.
