The Horror: Having an Application Refused with No Ability to Fix It
A patent application must contain a complete disclosure of the invention. If the written description contains insufficient or vague detail, it will be rejected for lack of clarity or for not sufficiently enabling the invention.
- The Clarity Crisis: One of the three most prevalent reasons patent applications are rejected is insufficient disclosure of the details of the invention.
- The Enablement Standard: The application must provide adequate details that would allow a person skilled in the relevant field to understand and replicate the invention.
- The Fatal Flaw: Once filed, “new material” cannot be introduced. If you leave out vital components, you can’t add them later, potentially making your claims worthless.
That last point is the kicker. It’s extremely difficult to overcome a rejection for insufficient disclosure because of it. You usually can’t just start over by file a new application, either, because by the time your application is examined and refused, that 12-month public disclosure window may have expired. You really need to get the level of detail right the first time.
Actionable Takeaway
Include detailed descriptions, drawings, flowcharts, and technical data. Your goal is to leave no room for ambiguity or vagueness.
Intellectual property is one of the most terrifyingly useful tools you have. If you’re a creator or other entrepreneur ready to build a frighteningly powerful brand and business, you need to know how to use it. You don’t have to face the darkness alone, though.
