Flakt, Inc., brings an interlocutory appeal for review of the scope of an injunction entered by the United States District Court for the District of Delaware dated May 29, 1992, in Civil Action No. 89-533-JJF, brought by Joy Technologies, Inc., for infringement of U.S. Patent No. 4,279,873 (the ’873 patent). This court stayed the injunction pending issuance of this decision. The stay of the injunction is vacated. The injunction is vacated and this aspect of the case is remanded to the district court with instructions to issue an injunction of a scope which conforms to this decision.
I.
BACKGROUND
Judgment was entered by the district court against Flakt for infringement of various claims of the ’873 patent. All of the claims in the ’873 patent are method claims directed to an improved process for desulfur-izing flue gas produced from the combustion of fuels which contain sulfur, such as coal. The particular method claimed in the ’873 patent includes thе partial recycle of calcium hydroxide used in the desulfurization process. Both Joy and Flakt are in the business of designing and building flue gas desulfuri-zation (FGD) plants throughout the United States for use in conjunction with industrial plants, such as power plants for production of electricity. 1
In response to Joy’s post-trial motion, the district court entered an order which states in its entirety, “[F]or the reasons set forth in the Memorandum Opinion issued this date *772 [Mаy 29,1992], IT IS HEREBY ORDERED that [Joy’s] Motion for Permanent Injunction is GRANTED as detailed in the Memorandum Opinion.” In the May 29, 1992, memorandum opinion, the district court discussed enjoining Flakt from further direct infringement, contributory infringement and inducement of infringement and spelled out that this meant Flakt was precluded from entering into any contracts during the term of the ’873 patent for the sale or construction of any air pollution control system designed to carry out the patented process. The sole issue respecting the scope of the injunction was framed by the district court as follows:
The critical question is whether sale and production of a machine/system capable of carrying out the patented process which requires five years to construct is considered contributory infringement when there will be no direct infringement, i.e. use of the machine/system, within the ‘patent term.

FORM OF THE INJUNCTION
The injunction issued by the district court does not conform to Fed.R.Civ.P. 65(d) (1993)

in that the order granting the injunction and the prohibitions set out in the memorandum opinion are not in a single document. While the parties address the form of the injunction only peripherally, this defect would require vacating and remanding the injunctive order for compliance as to form and specificity.

STANDARD OF REVIEW
While the right to exclude is the essence of the concept of property,
3
district courts are, nevertheless, given broad discretion under 35 U.S.C. § 283 (1988)
4
to determine whether the faсts of a case warrant the grant of an injunction and to determine the scope of the injunction.
Ortho Pharmaceutical Corp. v. Smith,
In addition to committing the grant of an injunction to a district court’s discretion, section 283 requires that the purpose behind the injunction must be “to prevent the violation of any right secured by patent.” 35 U.S.C. § 283.
See also Eli Lilly and Co. v. Medtronic, Inc.,
On appeal, Flakt argues that the injunction enjoins Flakt from performing acts which do not violate Joy’s rights secured by the ’873 patent. Joy responds that the broad scope of the injunction is necessary to protect it from infringement by Flakt and threatened infringement by others. Joy further argues that “duplicitous” conduct by Flakt provided the district court with justification for granting a broad injunction.
IV.
SCOPE OF INJUNCTION
A.
Sales by Flakt of Equipment Do Not Constitute Direct Infringement of the Method Patent
A utility patent grants to the patentee the right to exclude others from making, using, or selling the patented invention throughout the United States for the seventeen year term of the patent. 35 U.S.C. § 154 (1988). Notwithstanding various defenses to patent infringement which are not applicable to the present appeal, “whoever without authority makes, uses or sells any patented invention, within the United States during the term of the pаtent therefor, infringes the patent.” 35 U.S.C. § 271(a) (1988). The making, using, or selling of a patented invention is the usual meaning of the expression “direct infringement” and will be used herein in that sense.
See Hewlett-Packard Co. v. Bausch & Lomb Inc.,
Joy argues that the making or selling of an industrial plant designed to enable use of the patented FGD system may constitute a sale of the process claimed in the ’873 patent within the meaning of section 271(a), particularly where a contract contains enginеering details and performance guarantees. Thus, per Joy, the injunction merely prevents Flakt from depriving Joy of its exclusive right to sell its patented invention. We disagree. The law is unequivocal that the sale of equipment to perform a process is not a sale of the process within the meaning of section 271(a).

Standard Havens Products, Inc. v. Gencor Industries, Inc.,
B.
Sale of Flakt’s Equipment Does Not Constitute Infringement Absent Direct Infringement
Although not direct infringement under section 271(a), a party’s acts in connection with selling equipment may, however, constitute active inducement of infringement or contributory infringement of a method claim under 35 U.S.C. § 271(b) and (c).
6
Liability for either active inducement of infringement or for contributory infringement is deрendent upon the existence of direct infringement.
Deepsouth Packing Co. v. Laitram Corp.,
We find this case indistinguishable in substance from
Standard Havens.
There, we reviewed a district court’s award of damages against a manufacturer/seller of an apparatus which, if used in the United States during the term of the рatent at issue, would have infringed the method claims in the patent. The patentee presented no evidence that the apparatus was used in the United States.
Standard Havens,
Our holding in Standard Havens, first, reflects the previously discussed principle that a method claim is not directly infringed by the sale of an apparatus even though it is capable of performing only the patented *775 method. The sale of the apparatus is not a sale of the method. A method claim is directly infringed only by one practicing the patented method.
Second, Standard Havens holds that the act of selling equipment which will not be used so as to directly infringe a method claim cannot constitute one of the dependent types of infringement, that is, either contributory infringement or inducement of infringement. Joy seeks to distinguish Standard Havens because the intended use of the equipmеnt in that case was outside the United States while here the use will be beyond the term of the patent. We see this as a distinction without a difference. If the plant sold by Flakt cannot be used by the purchaser to infringe directly because it will not be operational within the term of the patent, Flakt cannot be guilty on a theory of contributory infringement with respect to that plant.
Joy next argues that Flakt can be enjoined from sales of noninfringing plants because it has been found to be an infringer. No doubt an injunction may be issued to enjoin Flakt from either direct or dependent infringement.
Pac-Tec, Inc. v. Amerace Corp.,
Joy finally argues that a district court may prevent an infringer from finessing a paten-tee out of sales by a “scheme to avoid patent infringement,” citing this court’s decision in
Paper Converting Machine Co. v. Magna-Graphics Corp.,
In
Paper Converting Machine,
the district court found the defendant liable for infringing the plaintiffs patent on an automatic paper rewinder.
Paper Converting Machine Co. v. Magna-Graphics Corp.,
Paper Converting Machine
is easily distinguishable from the present case. In
Paper Converting Machine, 745
F.2d at 19,
It is undisputed that [the defendant] intended to finesse [the patentee] out of the sale of a machine on which [the patentee] held a valid рatent during the life of that patent.
While a method claim had been asserted along with the apparatus claims, the method claim was not discussed nor found infringed by the Fort Howard devices. The analysis focused solely on the patented machine, not on the process implemented by the machine.
In the present case, the patent contains only method claims, which, as discussed above, are directly infringed only whеn the method is practiced. Joy is basically seeking *776 to convert its method claims into apparatus claims. The facts of Paper Converting Machine do not support the injunction in the present case.
In justifying the scope of the injunction, the district court relied on
Dawson Chem. Co. v. Rohm & Haas Co.,
In sum, the district court erred as а matter of law in holding that a seller of equipment could be a contributory infringer where it is established that “there will be no direct infringement, i.e., use of the machine/system within the patent term.” No argument is made that Flakt can be an active inducer of infringement without direct infringement. Thus, the injunction cannot be sustained on the ground that sales of equipment without use of the method within the patent term constitute contributory infringement of the method сlaim.
C.
Protection From Future Direct Infringement
Joy maintains that the scope of the injunction is necessary to prevent use of the patented method during the term of the patent which extends to July 21, 1998. Per Joy, some new plants could be completed within the term, and it would not know whether or not the process was used. Joy’s concern is a legitimate one. Flakt argues that it requires approximately five years to construct a plant, from contracting to completion, and that Joy’s fеar does not justify enjoining all of its future contracts. Flakt further represents that the equipment for the patented process can and will be disabled as it has been in existing plants which are now operating without any possible infringement of Joy’s rights.
Clearly, the scope of the injunction as issued cannot be sustained as necessary to prevent acts of direct infringement within the patent term. This is true even under Joy’s assertion that a plant can be completed in less than five years. Flakt is now precluded from contracting even where there is
no
possibility of an operational plant within the patent term and, thus, no possibility of direct infringement. This is not a case involving assembly line production and sale of a machine designed to practice a patented method which a purchaser can be expected to put to immediate use. Both parties agree there is a very long lead time before use can begin. Further, it is possible that in the interim between contracting for the construction of a plant and actually building the new plant, a new development will lead to a change in design and Flakt will never actually build a plant capable of performing the patented process.
See Ecodyne Corp. v. Croll-Reynolds Eng’g Co.,
We, of course, are not in a position to determine what length оf time it might take to complete a plant. We also do not know whether it is feasible to disable the equipment so that it cannot be tested by Flakt or used by its customers. If this is possible, however, it might be sufficient for protection of Joy’s interest to order Flakt to make *777 periodic reports to Joy as an alternative to prohibiting otherwise lawful sales activity. If direct infringement occurs with Flakt-sup-plied equipment, that is, the method is usеd before the patent term expires, Flakt would be liable not only for infringement but for contempt as well, even under a narrow injunction. It is in Flakt’s interest to take steps to preclude direct infringement.
The district court is, of course, in the best position to fashion an injunction tailored to prevent or remedy infringement.
Roche Prods. v. Bolar Pharmaceutical Co.,
In sum, we hold only that the present injunction which precludes Flakt from activities that are not necessary to prevent infringement of the patented process cannot stand.
D.
Duplicitous Conduct as Justification for Broad Injunctive Relief
Lastly, Joy argues that “Flakt succeeded in hiding from Joy the very existence of several infringing systems through many months of discovery” and therefore created a justification for broad injunctive relief. After questioning during oral argument, Joy conceded that it knew of the existence of these plants. While Joy' attempted to relate to the court what it really meant by the above statement, the end result is that this statement is simply unsupportable. The statement was apparently designed to cast Flakt in a bad light and to imply that the district court took such equitable factors into account when determining the scope of the injunction. Joy flirts dangerously closе to frivolity in this assertion. While vigorous advocacy is accepted, an officer of the court must not attempt to mislead the court. Joy’s argument that Flakt’s “concealment” supports a broad injunction is not grounded in fact.
Y.
CONCLUSION
The stay of the injunction and the injunction are vacated. The matter of an injunction is remanded to the district court for reconsideration. Any injunction must conform with Fed.R.Civ.P. 65(d). The new injunction may enjoin Flakt’s acts which constitute direct, induced or contributory infringement during the term of the patent. Whether additional conditions are necessary to ensure that Flakt does not enable direct infringement during the patent term by others of which Joy might be unaware, we leave to the district court to determine and to fashion an appropriate remedy therefor if necessary.

VACATED AND REMANDED.
Notes
. We are unable to determine from the partial recоrd presented in this appeal whether or not there was evidence that Flakt itself practiced the method, e.g., by testing the facilities. The jury affirmatively answered interrogatories that “Flakt systems" infringed literally and under the doctrine of equivalents. What entity practiced the patented method is not evident from this ambivalent question. Under other interrogatories, Flakt was specifically found to have engaged in contributory infringemеnt and inducement of infringement.
.Every order granting an injunction and every restraining order shall set forth the reasons for its issuance; shall be specific in terms; shall describe in reasonable detail, and not by reference to the complaint or other document, the act or acts sought to be restrained; and is binding only upon the parties to the action, their officers, agents, servants, employees, and attorneys, and upon thоse persons in active concert or participation with them who receive actual notice of the order by personal service or otherwise.

. 35 U.S.C. § 283 provides, "The several courts having jurisdiction of cases under this title may grant injunctions in accordance with the principles of equity to prevent the violation of any right secured by patent, on such terms as the court deems reasonable.”
. Becausе of the precise language of the statute it has been suggested that active inducement of infringement under 35 U.S.C. 271(b) (1988) may be “a type of
direct
infringement."
Hewlett-Packard,
. Under section 271(b) one who "actively induces infringement of a patent shall be liable as an infringer,” and under section 271(c) one who "sells ... a material or apparatus for use in practicing a patented process, constituting a material part of the invention, knowing the same to be especially made or especially adapted for use in an infringement of such patent, and not a staple article or commodity of commerce suitable for substantial noninfringing use, shall be liable as a contributory infringer.”
. In the interim between the appeal of the liability determination and the appeal of the damages award, this court was formed and thus obtained jurisdiction of the later appeal.
