MPEP 2100 – Patentability (4)
Yes, in some circumstances, a secret or confidential use of an invention can constitute public use under pre-AIA 35 U.S.C. 102(b). The MPEP explains:
“[S]ecrecy of use alone is not sufficient to show that existing knowledge has not been withdrawn from public use; commercial exploitation is also forbidden.”
This means that even if an invention is used secretly, if it’s being commercially exploited, it may still be considered a public use. However, the mere fact that an invention is used internally by the inventor or their company to develop future products that are never sold is not sufficient by itself to create a public use bar.
It’s important to note that “public” is not necessarily synonymous with “non-secret.” The determination of whether a use is public depends on various factors, including the nature of the activity, public access, confidentiality obligations, and commercial exploitation.

Generally, an inventor’s private use of an invention for their own enjoyment does not constitute public use under pre-AIA 35 U.S.C. 102(b). The MPEP provides guidance on this matter:
“An inventor’s private use of the invention, for his or her own enjoyment is not a public use.”
This principle is illustrated in the case of Moleculon Research Corp. v. CBS, Inc., where the court held that an inventor showing his inventive puzzle to close friends in his dorm room and later discussing it with his company president did not result in a “public use.” The key factor was that the inventor retained control over the invention.
However, it’s important to note that if the private use involves commercial exploitation or if the invention becomes accessible to the public without restrictions, it may still be considered a public use. The determination often depends on the specific circumstances and the level of control the inventor maintains over the invention.

No, public knowledge is not necessarily the same as public use under pre-AIA 35 U.S.C. 102(b). The MPEP clearly states:
“Mere knowledge of the invention by the public does not warrant rejection under pre-AIA 35 U.S.C. 102(b). Pre-AIA 35 U.S.C. 102(b) bars public use or sale, not public knowledge.”
However, it’s important to note that while public knowledge may not constitute public use under 102(b), it could potentially provide grounds for rejection under other sections of the patent law, such as pre-AIA 35 U.S.C. 102(a).

An invention is considered “ready for patenting” in the context of public use when it has been reduced to practice or when the inventor has prepared drawings or other descriptions of the invention that are sufficiently specific to enable a person skilled in the art to practice the invention. This concept is crucial in determining whether a public use or sale has occurred before the critical date. According to MPEP 2133.03(c):
“The on-sale bar of 35 U.S.C. 102(b) may apply even though the invention is not ready for use in a commercially marketable form.”
The MPEP further clarifies that an invention can be “ready for patenting” when:
- The invention is reduced to practice; or
- The inventor had prepared drawings or other descriptions of the invention sufficient to enable a person of ordinary skill in the art to practice the invention.
It’s important for inventors to be aware that even if an invention is not fully perfected, it may still be considered “ready for patenting” if it meets these criteria.

MPEP 2133.03(A) – "Public Use" (4)
