A patent is technically also required to teach to a person skilled in the prior art on how to build the invention.
Here is an excerpt from [1]: "Second, if the inventor did possess a best mode, it must be determined whether the written description disclosed the best mode such that a person skilled in the art could practice it."
I have heard that the recent changes to the US patent laws have weakened this [2], though I have never read the details.
