A more thorough explanation:

NONENABLEMENT

In the field of patents, nonenablement refers to the lack of clarity or completeness in a patent application's specification. This means that the information provided is not enough to teach a person skilled in the relevant field how to make and use the invention without having to do a lot of extra work. This is also known as a lack of enablement.

For example, if someone were to file a patent application for a new type of engine, but the application did not provide enough information on how to build or use the engine, it would be considered nonenablement. Another example would be if someone filed a patent application for a new type of medicine, but did not provide enough information on how to make or use the medicine safely and effectively.

These examples illustrate how nonenablement can make it difficult for others to understand and use the invention described in the patent application. This can be frustrating for people who want to build on the invention or use it in their own work, and it can also make it harder for the patent to be granted in the first place.
