Patent Law FAQ

Yes, an abandoned application can be used as prior art, but the extent of its use depends on several factors. Under MPEP 2127, abandoned applications that have been published can be used as prior art as of their publication date for all they teach. Unpublished abandoned applications may be available as prior art under certain circumstances, such as when they are incorporated by reference in a U.S. patent. It’s important to note that the abandonment status itself does not negate the application’s potential as prior art. For specific rules on using abandoned applications as prior art, consult MPEP 2127 and MPEP 901 on prior art.

No, an applicant is not required to conduct a prior art search before filing a patent application. The MPEP clearly states:

‘An applicant has no duty to conduct a prior art search as a prerequisite to filing an application for patent.’

This is supported by several court cases cited in the MPEP, including:

• Nordberg, Inc. v. Telsmith, Inc.
• FMC Corp. v. Hennessy Indus., Inc.
• American Hoist & Derrick Co. v. Sowa & Sons, Inc.

The ‘inquiry reasonable under the circumstances’ requirement of 37 CFR 11.18 does not create any new duty for applicants to conduct prior art searches. However, applicants and practitioners should be aware that providing false or misleading information during prosecution can jeopardize patent enforceability.

No, patent applicants are not required to conduct prior art searches before filing a patent application. This is clarified in the MPEP, which states:

An applicant has no duty to conduct a prior art search as a prerequisite to filing an application for patent. See Nordberg, Inc. v. Telsmith, Inc., 82 F.3d 394, 397, 38 USPQ2d 1593, 1595-96 (Fed. Cir. 1996); FMC Corp. v. Hennessy Indus., Inc., 836 F.2d 521, 526 n.6, 5 USPQ2d 1272, 1275-76 n.6 (Fed. Cir. 1987); FMC Corp. v. Manitowoc Co., 835 F.2d 1411, 1415, 5 USPQ2d 1112, 1115 (Fed. Cir. 1987); American Hoist & Derrick Co. v. Sowa & Sons, Inc., 725 F.2d 1350, 1362, 220 USPQ 763, 772 (Fed. Cir.), cert. denied, 469 U.S. 821, 224 USPQ 520 (1984).

However, conducting a prior art search can be beneficial for understanding the state of the art and assessing the potential patentability of an invention.

An examiner’s consideration of documents listed in an Information Disclosure Statement (IDS) is as follows:

• Documents are considered in the same manner as other documents in Office search files.
• The examiner conducts a proper field of search.
• For non-English language documents, consideration is limited to what can be understood from the concise statement and any drawings or chemical formulas.

The MPEP states: Consideration by the examiner of the information submitted in an IDS means that the examiner will consider the documents in the same manner as other documents in Office search files are considered by the examiner while conducting a search of the prior art in a proper field of search. (MPEP 609.05(b))

Regarding non-English documents, the Federal Circuit has noted: [A]s MPEP Section 609C(2) reveals, the examiner’s understanding of a foreign reference is generally limited to that which he or she can glean from the applicant’s concise statement…Consequently, while the examiner’s initials require that we presume that he or she considered the [foreign] reference, this presumption extends only to the examiner’s consideration of the brief translated portion and the concise statement. (Semiconductor Energy Laboratory Co. v. Samsung Electronics Co., 204 F.3d 1368, 1377-78, 54 USPQ2d 1001, 1008 (Fed. Cir. 2000))

No, filing an Information Disclosure Statement (IDS) is not considered an admission that a prior art search has been conducted. The MPEP clearly states:

The filing of an information disclosure statement shall not be construed as a representation that a search has been made. 37 CFR 1.97(g).

Furthermore, the MPEP emphasizes that There is no requirement that an applicant for a patent make a patentability search.

It’s important to note that submitting an IDS is also not an admission of the materiality of the information to patentability. The MPEP states:

The filing of an information disclosure statement shall not be construed to be an admission that the information cited in the statement is, or is considered to be, material to patentability as defined in 37 CFR 1.56(b). 37 CFR 1.97(h).
