Plaintiff, Paul Oravec, brought this action under the Copyright Act, 17 U.S.C. §§ 101 et seq., against several parties associated with the Trump Palace and the Trump Royale (collectively, “Trump Buildings”), twin high-rise condominiums in Sunny Isles Beach, Florida. Oravec alleged that these defendants infringed his copyrighted architectural designs through the design, development, and construction *1221 of the Trump Buildings. The district court granted summary judgment to defendants and denied Oravec’s motion for leave to file a third amended complaint. After thorough review of the record, we conclude that the grant of summary judgment was proper and that there was no abuse of discretion in the denial of leave to amend. Accordingly, we affirm.
I. BACKGROUND
Oravec was born in Czechoslovakia and was trained and licensed as an architect in that country. After immigrating to the United Statеs in 1982, Oravec worked as a designer for architectural firms in New York, and later for a Miami firm that designs and builds real estate and promotional displays. Although not licensed to practice architecture in the United States, Oravec has continued to pursue that interest during his spare time.
In 1995 and 1996, Oravec developed a design for a high-rise building that featured the use of alternating concave and convex segments and elevator cores protruding through the building’s roofline. Oravec applied to register this design with the U.S. Copyright Office and was issued a certificate of registration on July 1, 1996 (“1996 Copyright”). After making certain refinements, Oravec obtained an additional copyright registration on May 2, 1997 (“1997 Copyright”). 1 Hoping to see his design constructed, Oravec undertook efforts to market it to developers in South Florida and elsewhere. Between 1996 and 1999, Oravec mailed versions of his design to as many as 120 individuals and companies and made several in-person presentations to developers.
During the same time period, defendants Michael and Gil Dezer initiated the process of developing the beachfront resort that would be the site of the Trump Buildings. Michael Dezer purchased a parcel of land in Sunny Isles Beach and collaborated on its development with a company named Colonial Ridge Development, LLC (“Colonial Ridge”). In the late 1990s, Colonial Ridge hired defendant Sieger Suarez Architectural Partnership, Inc. (“Sieger Suarez”) to design two buildings for the property. The original Sieger Suarez designs consisted of a condominium hotel and a Y-shaped residential condominium. 2 Subsequently, the Dеzers acquired additional land and decided that a larger residential condominium should be constructed. Sieger Suarez modified its design, and the result was the design for the current Trump Palace. The district court found that this design was substantially complete in March of 2000. Later, after the purchase of additional property, the project was expanded to include a second residential condominium. Sieger Suarez designed this second building, which would become the Trump Royale, as essentially a mirror image of the Trump Palace.
On February 15, 2003, Oravec saw a newspaper advertisement featuring a photograph of a model of the Trump Palace. The following day, he visited the resort’s sales office and viewed models and brochures depicting the Trump Buildings. At the time, neither building had been constructed; only the foundation of the Trump Palace had been laid. Believing *1222 that the designs resembled his own, Ora-vec consulted with attorneys and was advised to secure copyright registrations for all of his unregistered designs in order to satisfy the jurisdictional prerequisites for an infringement action. See 17 U.S.C. § 411(a) (“[N]o action for infringement of the copyright in any United States work shall be instituted until preregistration or registration of the copyright claim has been made in accordance with this title.”).
Oravec thereafter obtained two additional copyright registrations, only one of which (the “March 2004 Copyright”) is relevant to this appeal. On this registration form, Oravec indicated that the submitted materials were derivative of the works covered by his three prior registered copyrights, which he listed by registration number. He also provided the following statement in space 6b, under the subheading “Material Added to This Work”: “This material includes all previous designs and versions and depict [sic] them in 3-D models/photographs, renderings/43 pages.” Oravec initially attempted to claim protection for these materials as architectural works, as he had done with respect to his previous designs. See 17 U.S.C. § 102(a)(8). However, after receiving his application, the Copyright Office informed Oravec that this claim was inconsistent with his statement that the claim pertained to sculptures, artwork, and photographs. See 17 U.S.C. § 102(a)(5) (establishing copyright protection for “pictorial, graphic, and sculptural works”). The Office advised Oravec: “If you have created original sculptures, artwork, and photographs that were based on previously registered architectural work claims, but you are not now registering any new architectural work authorship and plans, then space 2 [‘Nature of Authorship’] must reflect the new claim as described in space 6b” (emphasis omitted). The Office directed Ora-vec to amend his application by deleting the architectural work claim and checking only the boxes for “3-Dimensional sculpture,” “2-Dimensional artwork,” and “Photograph.” Oravec made these changes and re-filed his application.
In November 2004, Oravec filed suit under the Copyright Act against numerous individuals and entities associated with the Trump Buildings. Specifically, Oravec sued Sieger Suarez, its principals Charles M. Sieger and Jose J. Suarez, and real estate developers Sunny Isles Luxury Ventures L.C. and Dezer Properties LLC on a theory of direct copyright infringement. In addition, Oravec asserted claims of vicarious copyright infringement and contributory copyright infringement against various developer entities and their principals.
In April 2006, the parties filed cross motions for summary judgment on a variety of issues. The district court held three summary judgment hearings in July 2006. During the first hearing on July 7, the court expressed the view that Oravec could not prevail on his claims pertaining to the March 2004 Copyright because the construction of a building cannot, as a matter of law, infringe the copyright in a pictorial, graphic, or sculptural work (“PGS work”) registered under 17 U.S.C. § 102(a)(5). In response, Oravec filed a series of new copyright applications with the Copyright Office on July 11 in order to register the March 2004 Copyright materials as architectural works under § 102(a)(8). The following day, Oravec sought leave to file a third amended complaint based on these new registrations. At a hearing that same day, the court denied leave to amend because the registration certificates had yet to issue and because the deadline for filing amendments had passed more than a year earlier. Nine days later, Oravec received the requested certificates from the Copy *1223 right Office and moved the court to reconsider its denial of leave to amend.
On July 24, 2006, the court entered an order granting summary judgment to defendants on Oravec’s infringement claims and denying Oravec’s motion to amend. 3 The court found, inter alia, that Oravec could not establish infringement of his 1996 and 1997 Copyrights because no reasonable jury could find that the Trump Buildings are substantially similar to Ora-vec’s 1996 and 1997 designs. The court found that Oravec could not prevail on the basis of his March 2004 Copyright for the reasons indicated at the July 7 hearing. As to Oravec’s motion to amend, the court reiterated its conclusion that Oravec’s delay was unreasonable given the expiration of the deadline for filing amendments. The court further noted that trial was six weeks away and that Oravec had been on notice of the challenge to his March 2004 Copyright claim since April 10, 2006, the date the defendants filed their motion for summary judgment. Oravec now challenges each of these rulings.
II. DISCUSSION
A. Summary Judgment Standard
We review the district court’s grant of summary judgment
de novo,
construing all evidence in the light most favorable to Oravec, the non-moving party.
Leigh v. Warner Bros., Inc.,
B. 1996 and 1997 Copyrights
1. Legal Framework
To establish copyright infringement, “two elements must be proven: (1) ownership of a valid copyright, and (2) copying of constituent elements of the work that are original.”
Feist Publ’ns, Inc. v. Rural Tel. Serv. Co.,
We have defined substantial similarity as existing “where an average lay observer would recognize the alleged copy as having been appropriated from the copyrighted work.”
Original Appalachian Artworks, Inc. v. Toy Loft, Inc.,
In identifying the protected elements of a plaintiffs work, the court must be mindful of the fundamental axiom that copyright protection does not extend to ideas but only to particular expressions of ideas. 17 U.S.C. § 102(b) (“In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery....”);
Harper & Row Publishers v. Nation Enters.,
Nevertheless, in attempting to distinguish between ideas and expression, it is useful to note the policy purposes served by the distinction.
See Country Kids ‘N City Slicks, Inc. v. Sheen,
In addition to the idea/expression dichotomy, certain statutory provisions specific to architectural works further define the scope of available copyright protection. The Copyright Act’s definition of “architectural work” excludes “individual standard features” from the protectible elements of the design. 17 U.S.C. § 101. According to legislative history, such features include “common windows, doors, and other staple building components.” H.R.Reр. No. 101-735 (1990), as
reprinted in
1990 U.S.C.C.A.N. 6935, 6949;
see also T-Peg, Inc. v. Vermont Timber Works, Inc.,
2. Comparison of Works
Oravec bases his infringement claims on the following elements that he contends are present in both his designs and the Trump Buildings: (1) alternating concave and convex sections; (2) three prominent elevator shafts that protrude above the roof of the building; (3) rounded *1226 building ends; (4) constant radius curves; (5) holes in the building; (6) a twin tower design; (7) see-through floor plans; (8) a circular plaza; (9) a central fountain; and (10) a rooftop pool and landscape elements. 6 Examining these elements individually and collectively, the district court determined that the similarities between the Oravec designs and the Trump Buildings exist only at a conceptual level. Accordingly, the court concluded that no reasonable jury, properly instructed, could find the competing works substantially similar without implicitly finding that Ora-vec owns a copyright in an idea. For the reasons discussed below, we agree. 7
As the district court noted, the key distinctive features of Oravec’s designs are their use of alternating concave and convex sections and their use of three partially exposed elevator towers extending above the buildings’ roof lines. While such features also are present in the Trump Buildings, a comparison of the works reveals numerous significant differences in the expression of these elements. As to the concave/convex concept, one readily apparent difference is the fact thаt the alternating segments appear on both sides of Ora-vec’s designs but only on one side of the Trump Buildings. Even when viewing the Trump Buildings from that side, however, several other dissimilarities are evident. For example, Oravec’s designs contain five alternating segments, while the Trump Buildings have only three. Additionally, the segments in Oravec’s designs extend across the entire face of the building, while those in the Trump Buildings appear only in the middle portion between the two outer elevator towers. In Oravec’s designs, these segments are long and narrow, and each segment is placed on one side of the three elevator towers so as to create a void throughout the vertical center of the building. In the Trump Buildings, the segments appear only on the fagade of the building, and there is no vertical void created. Thеse differences are reflected in the buildings’ respective floor plans. Oravec’s 1997 design measures 320 feet long and 42 feet wide, and the entire floor plan has a pronounced, “banana-shaped” curve to it. The Trump Buildings have a more rectilinear shape, measuring 260 feet long and 72 feet wide at their narrowest points.
The expression of the elevator towers also differs significantly. Oravec’s elevator towers are free-standing and are located within the space created by the alternating convex and concave sections of the building. The Trump Buildings’ elevator towers are located within the solid structure of the building. In addition, in Ora-vec’s designs, a viewer can see only certain sections of the elevator towers because they are partially obstructed by the alternating convex and concave sections. In the Trump Buildings, the viewer can see the exteriors of the outer two elevator towers through the entire length of the building; only the center tower is partially obscured. The towers also differ in shape and orientation. Oravec’s elevator towers are cylindrical, while those in the Trump Buildings are ovals. In Oravec’s designs, the towers are clustered in the center of the building, and the middle tower is thicker than the two outer two. The towers in the Trump Buildings are spread out evenly, and all three are equal in diameter. Further, the two outer towers in the
*1227
Trump Buildings “are angled inward so that the leading edge of all three towers orient toward a focal point outside the building.”
Oravec v. Sunny Isles Luxury Ventures L.C.,
The remaining elements identified by Oravec — the use of rounded building ends, a constant radius on individual floor plans, holes in the building, a twin-tower design, “see-through” units, a circular plaza, a central fountain, and a rooftop pool with landscape elements — are best characterized as either individual standard features or ideas.
Cf. Sturdza,
With respect to the circular plazas, the district court properly found that these elements are not substantially similar because Oravec’s plaza lacks the intricate details expressed in that of the Trump Buildings. The same conclusion applies to the use of a circular fountain in each design. As to the constant radius curves and “see-through” floor plans, we have already noted that the floor plans in the respective designs differ dramatically. Finally, Ora-vec points to his use of a rooftop pool with landscape elements. However, the Trump Buildings do not have a rooftop pool, and the landscape elements in those buildings are not similar to any such features that are discernible in Oravec’s designs.
These differences, as well as others, preclude a finding of substantial similarity. While it is true that Oravec’s designs and the Trump Buildings have a number of features in common, those elements are similar only at the broadest level of generality. At the level of protected expression, the differences between the designs are so significant that no reasonаble, properly instructed jury could find the works substantially similar. As the district court observed, to conclude otherwise would require a finding that Oravec owns a copyright in the concept of a convex/concave formula or in that of using three external elevator towers that extend above the roof of a building. Such a conclusion would extend the protections of copyright law well beyond their proper scope.
Cf. Ale House Mgmt. v. Raleigh Ale House, Inc.,
For similar reasons, we also reject Oravec’s argument that he can establish substantial similarity on the basis of his selection of design elements. In Oravec’s view, the fact that the same combination of elements appears in both his designs and the Trump Buildings should have precluded summary judgment, notwithstanding the differences in the expression of those elements. However, while it is clear that an architect’s original selection or combination of elements can warrant copyright protection,
see Corwin, 475
F.3d at 1251;
T-Peg,
Accordingly, we affirm the grant of summary judgment as to Oravec’s 1996 and 1997 Copyrights.
C. March %00k Copyright
“[T]he holder of a copyright in an architectural plan ... has two forms of protection, one under the provision for an ‘architectural work’ under 17 U.S.C. § 102(a)(8), and another under the provision for a ‘pictorial, graphical, or sculptural work’ under 17 U.S.C. § 102(a)(5).”
T-Peg,
The Copyright Act provides that “no action for infringement ... shall be instituted until preregistration or registra
*1229
tion of the copyright claim has been made in accordance with this title.” 17 U.S.C. § 411(a). This registration requirement is a jurisdictional prerequisite to an infringement action.
M.G.B. Homes, Inc. v. Ameron Homes, Inc.,
Oravec directs our attention to several cases in which courts have exercised jurisdiction on the basis of this effective registration principle. For example, in
Streetwise Maps, Inc. v. VanDam, Inc.,
Oravec argues that the effective registration doctrine is appliсable to the facts of this case. He contends that, because he owns the architectural works depicted in his March 2004 materials, the March 2004 Copyright effectively registered those pri- or works. Therefore, he argues, the works need not be formally registered as architectural works in order to receive protection as such.
Oravec’s reliance on the effective registration doctrine is misplaced. As indicated, the cases applying that principle involved derivative or collective works that incorporated material from unregistered preexisting works. Here, Oravec’s March 2004 registration certificate does not identify any unregistered preexisting works. In fact, on the portion of the certificate calling for the identification of preexisting mаterial, Oravec listed only his 1996, 1997, and 2002 Copyrights — i.e., registered *1230 works. Oravec obviously does not need to rely on the effective registration doctrine to assert claims based on those designs. Now, however, Oravec appears to be arguing that the relevant “preexisting” works are the three-dimensional models registered by the March 2004 Copyright itself. According to Oravec, these works are preexisting because the photographs and computer renderings that were registered at the same time depict the models, and thus are derivative works. That interpretation, however, is not apparent from the registration certificate, which makes no distinction between the models and the other registered materials. It merely indicates that the models, photographs, and rendering's arе derivative of Oravec’s three previously registered designs.
At least one other court has found subject matter jurisdiction lacking where the registration certificate relied upon by the plaintiff did not properly identify the preexisting work upon which the infringement claim was based. In
I.M.S. Inquiry Management Systems, Ltd. v. Berkshire Information Systems, Inc.,
The court rejected this argument, finding that “the portion of the Registration Certificate requiring the identification of ‘Preexisting Material’ would have to refer to the preexisting matter that is the basis of this infringement action.” Id. at 529. In the court’s view, the plaintiffs failure to provide such information distinguished the case from Streetwise Maps, where the preexisting work was identified on the registration certificate for the derivative work. Id. In I.M.S., by contrast, there was no indication that the plaintiffs registration covered the work at issue in the suit, apart from the plaintiffs “current protestations to [that] effect.” Id. The court found such assertions insufficient to establish subject matter jurisdiction. Id.
We find the
I.M.S.
court’s reasoning persuasive and applicable to the facts of this case. With the exception of his three prior registered designs, Oravec’s March 2004 registration certificate does not identify any preexisting architectural works that the registered materials are based on or incorporate.
See
17 U.S.C. § 409(9) (providing that application for copyright registration shall include, “in the case of a compilation or derivative work, an identification of any preexisting work or works that it is based on or incorporates”). In particular, the certificate gives no indication that Oravec was attempting to claim separate protection for his three-dimensional models as preexisting architectural works. Oravec’s “current protestations” that the models should be treated as such cannot satisfy the registration requirement of § 411(a).
See I.M.S.,
*1231
Moreover, even assuming that Oravec created preexisting architectural works, he is attempting to sue on an aspect of those works — the right to prevent construction of buildings embodying his design — that is not included in the PGS work he did register. As discussed, courts recognizing the effective registration doctrine have held that the registration of a derivative work satisfies the registration requirement for all aspects of the
registered
work, even the aspects copied from an unregistered preexisting work, so long as the owner of both copyrights is the same.
See, e.g., Streetwise Maps,
But that is exactly what Oravec is attempting to do here by seeking damages for the construction of the Trump Buildings. As noted, a PGS copyright cannot be infringed by an as-built structure. Thus, even assuming Oravec has unregistered preexisting architectural works copyrights in the architectural designs embodied in the March 2004 Copyright, the right to prevent the construction of buildings mirroring those designs is an aspect of those preexisting architectural works copyrights that cannot be (and thus was not) incorporated into his March 2004 PGS Copyright. Thus, Oravec seeks to sue on an aspect of an unregistered underlying work that is not incorporated into the derivative work he did register. The effective registration doctrine cannot be stretched that far.
Accordingly, we hold that Oravec’s March 2004 Copyright does not entitle him to claim architectural work protection for his registered PGS works. We affirm the grant of summary judgment as to the March 2004 Copyright.
D. Motion to Amend Complaint
Finally, Oravec argues that the district court erred in denying him leave to amend his complaint to correct the jurisdictional defect arising from the PGS copyright registration. He contends that the court should have granted his motion because there was no undue delay and because the exclusion of the March 2004 claims results in injustice. Alternatively, Oravec argues that amendment of the complaint was unnecessary because his registration of the materials as architectural works in July 2006 cured any jurisdictional defect.
We “will only reverse a district court’s denial of a motion to amend in instances in which the district court has clearly abused its discretion.”
Henson v. Columbus Bank & Trust Co.,
We have recognized that Rule 16(a)’s good cause standard “precludes modification [of the scheduling order] unless the schedule cannot be met despite the diligence of the party seeking the extension.”
See Sosa,
Oravec’s alternative argument that his registration of the March 2004 materials as architectural works eliminated the need to amend his complaint likewise is without merit. Oravec relies on
Positive Black Talk Inc. v. Cash Money Records, Inc.,
III. CONCLUSION
For the foregoing reasons, we affirm the judgment of the district court.
AFFIRMED.

Notes
. Oravec obtained a copyright registration for another version of his design in 2002. Ora-vec admitted that the defendants could not have copied this work because their designs were already completed at the time the 2002 materials were created. The court also found that Oravec had abandoned any copyright interest he had in thе 2002 design. Oravec does not challenge these findings on appeal.
. The hotel is now known as the Trump International Sonesta Resort. Its design is not at issue in this case.
. These rulings disposed of all other issues in the case. Nonetheless, the court also ruled on several additional claims and defenses raised by the parties. Because we affirm the district court on the dispositive issues, we need not address the other portions of its decision.
. If thé plaintiff cannot demonstrate access, he or she still may establish copying by showing that the works are “strikingly similar.”
Corwin v. Walt Disney Co.,
. In
Herzog,
we approved a district court opinion that framed this analysis as a two-part inquiry similar to that established by the Ninth Circuit in
Sid & Marty Krofft Television Productions, Inc. v. McDonald’s Corp.,
Undеr the extrinsic test, a court will inquire into whether, as an objective matter, the works are substantially similar in protected expression. As a part of this test, a court will determine whether a plaintiff seeks to protect only uncopyrightable elements; if so, the court will grant summary judgment for defendant. Under the extrinsic test, expert testimony and analytic dissection are appropriate. Under the intrinsic test, a court will determine whether, upon proper instruction, a reasonable jury would find that the works are substantially similar. A court may grant summary judgment for defendant as a matter of law if the similarity between the two works concerns only non-copyrightable elements of the plaintiff’s work or if no reasonable jury would find that the two works are substantially similar.
This aspect of the
Herzog
decision is something of an anomaly in our copyright jurisprudence. Prior to that case, the extrinsic/intrinsic framework had not been recognized in this circuit, and we have not referenced it in subsequent published decisions dealing with the issue of substantial similarity.
See, e.g., Suntrust Bank v. Houghton Mifflin Co.,
. The first five of these elements appear in Oravec's 1996 design. The remaining elements were added in the 1997 design.
. To illustrate our analysis, we have attached selected images of the designs as appendices to this opinion. Appendix A shows Oravec’s 1997 design, and Appendix B shows the Trump Palace as constructed.
.
See, e.g., Imperial Homes Corp. v. Lamont,
. Our conclusion is not altered by the statement that Oravec provided on the registration certificate under the subheading "Material Added to This Work”: "This material includes all previous designs and versions and depict [sic] them in 3-D models/photographs, renderings....” This statement is insufficient for effective registration purposes, as it does not indicate what specific preexisting works (other than the three registered designs) are being referenced. See 17 U.S.C. § 101 (defining "architectural work” as "the design of a building as embodied in any tangible medium of expression”) (emphasis added). The state *1231 ment certainly does not suggest that the three-dimensional models are themselves the preexisting works.
