MEMORANDUM ORDER
THYNGE, United States Magistrate Judge.
This is a patent infringement case. Pending before the court is Universal Avionics Systems Corp.'s ("Universal") Motion In Limine seeking to preclude plaintiffs Honeywell International Inc. and Honeywell Intellectual Properties Inc. (collectively "Honeywell") from introducing expert testimony regarding alleged infringement under the doctrine of equivalents. Specifically, Universal's motion recites: "Honeywell should be precluded from introducing any evidence of alleged infringement under the doctrine of equivalents because John Hansman, Honeywell's technical witness, provided conclusory opinions unsupported by any analysis in his report with respect to this issue."[1]
In Graver Tank & Mfg. Co., Inc. v. Linole Air Products Co., the United States Supreme Court stated that "a patentee may invoke [the] doctrine [of equivalents] to proceed against the producer of [an allegedly infringing] device if it performs substantially the same function in substantially *116 the same way to obtain the same result."[2] The Federal Circuit has since "recognized the function, way, result test applied in Graver Tank."[3] Moreover, "substantial identity must be proven with regard to all three elements of the doctrine specified in Graver Tank: function performed, means by which function is performed, and result achieved."[4]
"[T]he evidentiary requirements necessary to prove infringement under the doctrine of equivalents [include] ... the need to prove equivalency on a limitationby-limitation basis ... [and] requir[es] equivalency to be proven with particularized testimony and linking argument."[5] The purpose of "[t]hese evidentiary requirements [is to] assure that the factfinder does not, under the guise of applying the doctrine of equivalents, erase a plethora of meaningful structural and functional limitations of the claim on which the public is entitled to rely in avoiding infringement." [6] Therefore, "[i]n order to prevent the doctrine from expanding a patent's protection beyond the scope of its claims, the Federal Circuit has warned that the application of the doctrine of equivalents should be `the exception .. . [and] not the rule' in patent infringement actions."[7] The Federal Circuit has summarized the burden of establishing infringement under the doctrine of equivalents, stating that:
[A] patentee must ... provide particularized testimony and linking argument as to the "insubstantiality of the differences" between the claimed invention and the accused device or process, or with respect to the function, way, result test when such evidence is presented to support a finding of infringement under the doctrine of equivalents. Such evidence must be presented on a limitation-by-limitation basis. Generalized testimony as to the overall similarity between the claims and the accused infringer's product or process will not suffice.[8]
A plaintiff asserting infringement under the doctrine of equivalents "must present evidence and argument concerning the doctrine and each of its elements .... The evidence and argument on the doctrine of equivalents cannot merely be subsumed in plaintiffs case of literal infringement.... Accordingly, the fact there was evidence and argument on literal infringement, that may also bear on equivalence," is insufficient to demonstrate infringement under the doctrine of equivalents.[9]
According to Universal, the expert reports submitted by Honeywell's expert, *117 Dr. John Hansman, Jr., fail to meet these requirements for establishing infringement under the doctrine of equivalents.
The only claim which remains at issue in this litigation is claim 1 of U.S. Patent No. 4,914,436 ("the '436 patent").[10] Claim 1 contains five elements and reads as follows:
1. A system for use in an aircraft for providing an enabling envelope for a ground proximity warning system for an aircraft comprising:
[1] a first source of signals representative of the longitude and latitude of an airport;
[2] a second source of signals representative of the current longitude and latitude of said aircraft;
[3] means responsive to said first source of signals representative of the longitude and latitude of said airport and said second source of signals representative of the current longitude and latitude of said aircraft for computing the distance of said aircraft from said airport and providing an enabling envelope for enabling the warning system as a function of said distance of the aircraft with respect to said airport;
[4] a source of signals representative of the relative angular position of a particular runway with respect to the heading of the aircraft; and
[5] means responsive to said first and second sources of signals for providing a signal representative of the alignment of the aircraft with the runway by determining the angle between the runway and the heading of the aircraft.
Attached as Exhibit 2 to the Opening Expert Report of Robert John Hansman, Jr. Regarding Defendant Universal[11] is a chart detailing Hansman's conclusions supporting his opinion that the accused Universal product infringes the '436 patent. Hansman's report details evidence purportedly supporting his opinion of literal infringement of Universal's Terrain Awareness Warning System ("TAWS") for each of the elements of claim 1 of the '436 patent. That report makes no argument for infringement under the doctrine of equivalents with regard to the first and second limitations of the '436 patent.[12] Hansman's report purports to provide evidence of infringement under the doctrine of equivalents for the third, forth, and fifth elements of claim 1.
The third element of claim 1 reads:
means responsive to said first source of signals representative of the longitude and latitude of said airport and said second source of signals representative of the current longitude and latitude of said aircraft for computing the distance of said aircraft from said airport and providing an enabling envelope for enabling the warning system as a function of said distance of the aircraft with respect to said airport.[13]
With regard to infringement under the doctrine of equivalents of the third element of claim 1, Hansman's report recites:
In its Interrogatory Responses, Universal states that its TAWS does not employ a "means responsive" as required by the claim element. Universal does *118 not provide any explanation of the basis for its position. Based on the reasons explained above, I conclude that it does include the claimed element. In addition, there is no substantial difference between the means by which Universal enables its MGCB capability and the means described in the patent. The function of the means of the patent is to provide an enabling envelope for enabling the warning system as a function of the aircraft's distance to the airport. The way the enabling means of the patent performs this function is by providing an enabling envelope as a function of the distance to the airport. The result is that one or more modes of the warning system are enabled as a function of the distance to the airport. Universal's TAWS functions to enable its MGCB capability in substantially the same way, with substantially the same result as the means of the claim.[14]
Element 4 of claim 1 reads: a source of signals representative of the relative angular position of a particular runway with respect to the heading of the aircraft.[15]
With regard to infringement under the doctrine of equivalents of the fifth element of claim 1, Hansman's report recites:
In its Interrogatory Responses, Universal states that its TAWS does not include a source of signals representative of the relative angular position of a runway with respect to the "heading", as the term is defined in the patents. Universal does not provide an explanation for the basis of its position. Based on the reasons explained above, I conclude that it does include the claimed element. In addition, there is no substantial difference between the signals of Universal's system and the signals described in the claim. The function of the signals in this claim is to represent the relative angular position of a particular runway with respect to the "heading" (bearing) of the aircraft. The way the signals represent the relative angular position is by representing the orientation or bearing of the runway and the angle formed between the line segment connecting the aircraft's position to an airport and a reference datum, or the bearing of the aircraft. The result is signals representative of the relative angular position of a particular runway with respect to the "heading" (bearing) of the aircraft. The signals vBear and rwBear of the Universal system perform substantially the same function, in substantially the same way, to achieve substantially the same result.[16]
The fifth element of claim 1 reads:
means responsive to said first and second sources of signals for providing a signal representative of the alignment of the aircraft with the runway by determining the angle between the runway and the heading of the aircraft.[17]
With regard to infringement under the doctrine of equivalents of the fifth element of claim 1, the Hansman report recites:
In its Interrogatory Responses, Universal states that its TAWS does not include a "means responsive" as required by this claim element. Universal has not provided an explanation of the basis for its position. Based on the reasons explained above, I conclude that it does include the claimed element. In addition, there is no substantial difference *119 between the Universal system and this element of the claim. The function of this element is to provide a signal representative of the alignment of the aircraft with the runway. The way this element performs this function is by determining the angle between the runway and the "heading" (bearing) of the aircraft. The result is that the invention determines a signal representative of the aircraft's alignment with the runway. Universal's TAWS performs substantially the same function, in substantially the same way, to achieve substantially the same result through its calculation of the difference between rwBear and vBear.[18]
In each of the above-quoted passages, Hansman states that "there is no substantial difference between" the particular element discussed and certain aspects of Universal's TAWS followed by a quotation or rewording of '436 patent's claim language purportedly setting forth the function/way/result elements of the Graver Tank test and concludes with a conclusory statement declaring that certain aspects of Universal's TAWS have "substantially the same" function/way/result as the element being discussed.
Although Federal Circuit precedent
does not go so far as to require recitation of the magic words `function', `way', and `result', we think that it at least requires the evidence to establish what the function, way, and result of both the claimed device and the accused device are, and why those functions, ways and results are substantially the same.[19]
Here, Hansman's conclusory statements concerning Universal's TAWS are not sufficient evidence as to "why those functions, ways and results are substantially the same" as the disputed claim 1 elements of the '436 patent.[20] To the extent that Honeywell seeks to rely on the detailed description purportedly supporting direct infringement contained in Hansman's report to support a doctrine of equivalents argument, such reliance is insufficient.[21]
*120 Furthermore, the court notes that Federal Rule of Civil Procedure 26(a)(2)(B) requires that:
Except as otherwise stipulated or directed by the court, [the disclosure of expert testimony] shall, with respect to a witness who is retained or specially employed to provide expert testimony in the case ... be accompanied by a written report prepared and signed by the witness. The report shall contain a complete statement of all opinions to be expressed and the basis and reasons therefore; the data or other information considered by the witness in forming the opinions; any exhibits to be used as a summary of or support for the opinions.[22]
The Advisory Committee Notes to the 1993 Amendments regarding paragraph (a)(2)(B) of Rule 26 provides that:
persons retained or specially employed to provide expert testimony ... must prepare a detailed and complete written report, stating the testimony the witness is expected to present during direct examination, together with the reasons therefor. The information disclosed under the former rule in answering interrogatories about the `substance' of expert testimony was frequently so sketchy and vague that it rarely dispensed with the need to depose the expert and often was even of little help in preparing for a deposition of the witness, Revised Rule 37(c)(1) provides an incentive for full disclosure; namely, that a party will not ordinarily be permitted to use on direct examination any expert testimony not so disclosed.... [T]he report, which is intended to set forth the substance of the direct examination, should be written in a manner that reflects the testimony to be given by the witness ....[23]
To the extent that Honeywell's expert were to be permitted to testify concerning purported infringement of Universal's TAWS under the doctrine of equivalents, therefore, that testimony would necessarily be limited to the conclusory assertions of infringement under the doctrine. Because that testimony is insufficient for that purpose, Universal would be entitled to a directed verdict of non-infringement under the doctrine of equivalents.
As a result of a lack of "particularized testimony and linking argument" contained in Hansman's report and the limitation which would be imposed in any event by Rule 26(a)(2)(B) on Hansman's testimony with regard to Universal's purported infringement under the doctrine of equivalents:
IT IS ORDERED THAT:
Universal Avionics Systems Corp.'s motion in limine (D.I. 128, Motion In Limine # 4) is GRANTED.

Advanced Energy Industries, Inc., 325 F.Supp.2d 471, 473 (D.Del. 2004) ("Conclusory statements are not enough to sustain a claim of equivalence.").
[21]  At the pre-trial conference, Honeywell stated that with regard to Universal's contention that Hansman's report did not include sufficient particularized evidence to support a doctrine of equivalents argument that "If [Universal] want[s] to point me to something where [Hansman] just gave a summary conclusion, I can believe there is something. Because there aresome of these elements or those claim issues, these claim issues where once the expert has explained why the expert believes the device infringes literally, there is quite literally nothing else to say.... I assume there arethey haven't pointed you to one situation where there is simply nothing else to say. It infringes literally because it does X, Y, and Z. And for those same reasons, it functions. It does the same thing in the same way to the same degree." D.I. 132 at 243-44. Universal responded that such argument "would merge the principles of literal infringement with the Doctrine of Equivalents. And the law is pretty clear that's not good enough. You can't just offer the conclusory opinions. . . . [Honeywell's expert can not] simply boot-strap [his] conclusions with respect to literal infringement and extend them to the infringement under the Doctrine of Equivalents." D.I. 132 at 244. Precedent from the Federal Circuit and this district support Universal's position on this point. See, e.g., Lear Siegler, 873 F.2d at 1425 ("The evidence and argument on the doctrine of equivalents cannot merely be subsumed in plaintiff's case of literal infringement."); MKS Instruments, Inc. v. Advanced Energy Industries, Inc., 325 F.Supp.2d 471, 473 (D.Del. 2004) ("[Ijnfringement by equivalence is not subsumed by literal infringement and, therefore, evidence of literal infringement, alone, does not establish infringement under the doctrine of equivalents.").
