MPEP 2100 – Patentability (7)
MPEP 2114 provides guidance on distinguishing apparatus claims from method claims, particularly when functional language is involved. The manual states:
“While features of an apparatus may be recited either structurally or functionally, claims directed to an apparatus must be distinguished from the prior art in terms of structure rather than function.”
This means that for apparatus claims, the focus should be on the structural elements rather than how the apparatus functions. In contrast, method claims are defined by the steps or actions performed. The MPEP further clarifies:
“The recitation of a new intended use for an old product does not make a claim to that old product patentable.”
This highlights that merely describing a new way to use an existing apparatus doesn’t make it patentable. To be patentable, an apparatus claim must have structural differences from the prior art. If an applicant wants to protect a specific way of using an apparatus, they should consider filing method claims in addition to apparatus claims.

MPEP 2114 addresses recitations of the manner in which an apparatus is intended to be employed. According to the manual:
“[A]pparatus claims cover what a device is, not what a device does.” Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1469, 15 USPQ2d 1525, 1528 (Fed. Cir. 1990) (emphasis in original).
This means that the manner of operating the device does not differentiate apparatus claims from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. The MPEP further states:
“A claim containing a “recitation with respect to the manner in which a claimed apparatus is intended to be employed does not differentiate the claimed apparatus from a prior art apparatus” if the prior art apparatus teaches all the structural limitations of the claim. Ex parte Masham, 2 USPQ2d 1647 (Bd. Pat. App. & Inter. 1987)”
This guidance emphasizes that the focus should be on the structural limitations of the apparatus claim, rather than its intended use.

In patent claims, particularly for apparatus claims, the phrases “capable of” and “configured to” can have different implications:
- “Capable of” generally refers to an inherent ability or potential of the structure to perform a function, even if it’s not specifically designed for that purpose.
- “Configured to” implies that the structure is specifically designed or arranged to perform the stated function.
According to MPEP 2114, “[A]pparatus claims cover what a device is, not what a device does.” This means that the capability of a prior art device to perform the claimed function is often sufficient to anticipate the claim, regardless of whether it’s explicitly stated to be “configured to” perform that function.
However, “configured to” language may be given more weight if it implies structural modifications that are not present in a prior art reference that is merely “capable of” performing the function.
To learn more:
The material or article worked upon generally does not limit apparatus claims. As stated in MPEP 2115: “Inclusion of the material or article worked upon by a structure being claimed does not impart patentability to the claims.” This principle is based on legal precedents such as In re Otto and In re Young.
The MPEP further explains: “Claim analysis is highly fact-dependent. A claim is only limited by positively recited elements.” This means that the focus should be on the structural elements of the apparatus itself, not the materials it processes.
To learn more:
Yes, method claims can reference limitations from apparatus claims, as long as the reference is clear and does not introduce confusion. The MPEP 2173.05(f) provides an example of an acceptable reference:
“A method of producing ethanol comprising contacting amylose with the culture of claim 1 under the following conditions …..”
Additionally, the MPEP cites a relevant case:
“See also Ex parte Porter, 25 USPQ2d 1144 (Bd. Pat. App. & Inter. 1992) (where reference to “the nozzle of claim 7″ in a method claim was held to comply with 35 U.S.C. 112, second paragraph).”
These examples demonstrate that method claims can reference specific elements or entire apparatus claims, provided the reference is clear and does not create indefiniteness issues.

In re Casey is another significant case discussed in MPEP 2115 that relates to material worked upon in patent claims. The MPEP summarizes the case as follows:
In In re Casey, 370 F.2d 576, 152 USPQ 235 (CCPA 1967), an apparatus claim recited “[a] taping machine comprising a supporting structure, a brush attached to said supporting structure, said brush being formed with projecting bristles which terminate in free ends to collectively define a surface to which adhesive tape will detachably adhere, and means for providing relative motion between said brush and said supporting structure while said adhesive tape is adhered to said surface.”
The court upheld an obviousness rejection, stating that “the references in claim 1 to adhesive tape handling do not expressly or impliedly require any particular structure in addition to that of Kienzle.” This case reinforces the principle that the material worked upon (in this case, adhesive tape) does not necessarily impart patentability to an apparatus claim if it doesn’t result in a structural difference.
To learn more:
In re Young is another important case cited in MPEP 2115 that affects patent claim interpretation, particularly for apparatus claims. The MPEP states:
In Young, a claim to a machine for making concrete beams included a limitation to the concrete reinforced members made by the machine as well as the structural elements of the machine itself. The court held that the inclusion of the article formed within the body of the claim did not, without more, make the claim patentable.
This case reinforces the principle that the inclusion of the material or article worked upon by an apparatus does not automatically confer patentability. Patent examiners and practitioners should focus on the structural elements of the claimed apparatus rather than the output it produces.

MPEP 2115 – Material Or Article Worked Upon By Apparatus (3)

Yes, method claims can reference limitations from apparatus claims, as long as the reference is clear and does not introduce confusion. The MPEP 2173.05(f) provides an example of an acceptable reference:
“A method of producing ethanol comprising contacting amylose with the culture of claim 1 under the following conditions …..”
