From Pleadings Through Trial
A copyright complaint should identify the registered work, the registration, and what was copied.
· Law checked through October 21, 2026
In Short
Early motions often test registration, personal jurisdiction, the limitations period, and, in the Fifth Circuit, fair use, which can be decided on the pleadings. Discovery in software cases centers on source code and forensic evidence. Either side may demand a jury, including on the amount of statutory damages.
Common situations.
- A defendant moves to dismiss because the complaint does not say what elements of the work were copied.
- A software plaintiff needs access to the defendant's source code without exposing it to competitors.
- A plaintiff must decide whether to elect statutory damages before the jury deliberates.
- A defendant's server logs were deleted after the demand letter arrived.

Discovery.
- Source code. A protective order can limit access to outside counsel and experts, on standalone computers, with restrictions on printing (Fed. R. Civ. P. 26(c)).
- Forensics. Device images, repository histories, and server logs often show when and how material was copied.
- Preservation. A party that fails to take reasonable steps to preserve electronically stored information faces measures under Rule 37(e), including an adverse-inference instruction if it acted with intent to deprive the other side of the information (Fed. R. Civ. P. 37(e)(2)).
- Money. Revenue and cost data for a profits claim, and licensing history for an actual-damages claim. See Copyright Remedies.
Experts.
- Similarity. In software cases, experts help the court apply the abstraction-filtration-comparison method to separate protected from unprotected elements (Eng'g Dynamics, Inc. v. Structural Software, Inc., 26 F.3d 1335 (5th Cir. 1994)). For music, experts may testify about similarities in melody, rhythm, and structure.
- Damages. Lost license fees, the defendant's revenue attributable to the infringement, and apportionment.
- Admissibility. The proponent must show that the testimony more likely than not meets the reliability requirements of Rule 702 (Fed. R. Evid. 702, as amended Dec. 1, 2023). See Summary Judgment, Experts, and Daubert, in the patent section.
Summary judgment.
Substantial similarity is usually a question for the jury, but summary judgment is proper if no reasonable juror could find substantial similarity of protected expression (Peel & Co. v. Rug Mkt., 238 F.3d 391 (5th Cir. 2001)). Access may also be decided on summary judgment when the plaintiff offers only a bare possibility (Armour v. Knowles, 512 F.3d 147 (5th Cir. 2007); Batiste v. Lewis, 976 F.3d 493 (5th Cir. 2020)). Copyrightability, fair use, and the § 412 limits on remedies can also be decided on summary judgment when the material facts are not disputed.
Trial.
- Jury. Either side may demand a jury on liability and damages, including on the amount of statutory damages (Feltner v. Columbia Pictures Television, Inc., 523 U.S. 340 (1998)).
- Election. The owner may elect statutory damages instead of actual damages and profits at any time before final judgment (17 U.S.C. § 504(c)(1)).
- Willfulness and innocence. The fact-finder decides whether infringement was willful, which raises the statutory range, or innocent, which can lower it (§ 504(c)(2)).
- After the verdict. Motions for judgment as a matter of law and for a new trial (Fed. R. Civ. P. 50, 59), and a motion for attorney's fees within 14 days after judgment (Fed. R. Civ. P. 54(d)(2)).
