What is the “written description requirement” in patent law?

The written description requirement is a crucial aspect of patent law that ensures an inventor has adequately described their invention in the patent application. According to MPEP 2304.02(d), “The written description requirement is met so long as the application or priority application sufficiently described the subject matter to a person skilled in the art.”

It’s important to note that this requirement doesn’t necessarily demand actual examples or a reduction to practice. The key is that the description should be sufficient for a skilled person in the field to understand the invention.
