MPEP 2100 – Patentability (3)
What is the significance of drawings in proving conception for a patent?
Drawings play a crucial role in proving conception for a patent. The MPEP 2138.04 highlights their importance:
“A conception must encompass all limitations of the claimed invention” and “is complete only when the idea is so clearly defined in the inventor’s mind that only ordinary skill would be necessary to reduce the invention to practice, without extensive research or experimentation.“
In this context, drawings are significant because:
- They provide a visual representation of the inventor’s mental picture of the invention.
- Detailed drawings can demonstrate that the inventor had a complete conception of all aspects of the invention.
- Drawings can help prove that the invention was “ready for patenting” at the time of conception.
- They can serve as corroborating evidence to support the inventor’s testimony about conception.
The MPEP also notes: “The inventor’s consideration of all the structural details is not required,” suggesting that while drawings are important, they don’t need to include every minute detail to prove conception. However, the more comprehensive and clear the drawings are, the stronger the evidence of conception.

Can an inventor’s testimony alone prove conception in a patent case?
While an inventor’s testimony is important, it is generally not sufficient on its own to prove conception in a patent case. The MPEP 2138.04 states:
“An inventor’s testimony, standing alone, is insufficient to prove conception, as some form of corroboration is required.”
This requirement for corroboration serves several purposes:
- It helps verify the accuracy of the inventor’s recollection
- It protects against fraudulent claims
- It ensures that the conception date is supported by objective evidence
Corroborating evidence can come in various forms, such as contemporaneous documents, witness testimony, or physical exhibits. The key is that there must be some independent evidence that supports the inventor’s claim of conception beyond their own statement.

Conception and reduction to practice are two distinct steps in the inventive process. According to MPEP 2138.04, conception is the mental part of the inventive act, while reduction to practice involves actually creating or performing the invention.
The MPEP states:
“Conception has been defined as ‘the complete performance of the mental part of the inventive act’ and it is ‘the formation in the mind of the inventor of a definite and permanent idea of the complete and operative invention as it is thereafter to be applied in practice….’”
Reduction to practice, on the other hand, can be either actual (physically creating the invention) or constructive (filing a patent application with a sufficient description). In most cases, conception occurs before reduction to practice. However, the MPEP notes that in some unpredictable fields, such as chemistry and biology, conception and reduction to practice may occur simultaneously:
“On rare occasions conception and reduction to practice occur simultaneously in unpredictable technologies.”
Understanding this distinction is crucial for determining inventorship and priority dates in patent law.
