Your Wilmington Intellectual Property Attorney
Finding out that someone is using your invention, your name, or your creative work without permission is unsettling. This page explains the federal and North Carolina rules that most often decide how an intellectual property matter from Wilmington unfolds. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for New Hanover County, North Carolina’s own trademark and trade secret rules, and what an infringement claim involves. These rules apply across North Carolina, and an attorney familiar with the Eastern District of North Carolina can explain what to expect there.
Deadlines and Courts: The Short Version
- Patent term and damages: a patent lasts 20 years from the filing date of the application (35 U.S.C. 154(a)(2)), and no recovery can be had for infringement more than six years before the complaint (35 U.S.C. 286).
- Infringing a registered mark means using a reproduction, counterfeit, copy, or colorable imitation in a way likely to cause confusion (15 U.S.C. 1114(1)(a)).
- Three years to bring a copyright claim (17 U.S.C. 507(b)), and federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)).
- Federal trade secret claims must be brought within 3 years after the misappropriation is discovered or should have been discovered with reasonable diligence (18 U.S.C. 1836(d)).
- A federal case from Wilmington goes to the Eastern District of North Carolina (28 U.S.C. 113), which sits in Elizabeth City, Fayetteville, Greenville, New Bern, Raleigh, Wilmington, and Wilson.
The Four Main Areas of Intellectual Property Law
For an invention, the question is whether it fits one of the four categories in 35 U.S.C. 101, and if a patent is granted, it lasts for 20 years measured from the application filing date (35 U.S.C. 154(a)(2)).
Names, logos, and slogans that tell customers who is behind a product are trademarks, defined in 15 U.S.C. 1127 as any word, name, symbol, or device used to identify and distinguish a person’s goods and to indicate their source. A service mark does the same job for services.
For creative work, copyright arises in original works of authorship fixed in a tangible medium of expression (17 U.S.C. 102(a)). The limit in 17 U.S.C. 102(b) means the underlying idea or method is not protected even when the way it is expressed is.
Trade secret protection depends on two things: the owner took reasonable measures to keep the information secret, and the information has independent economic value because it is not generally known or readily ascertainable (18 U.S.C. 1839(3)). Formulas, methods, processes, programs, and codes can all qualify.
Deadlines for Intellectual Property Claims
Three years is the copyright limit in 17 U.S.C. 507(b), measured from when the claim accrued. Registration comes first under 17 U.S.C. 411(a), so the clock and the registration process can overlap.
Discovery drives the trade secret clock. A civil action under 18 U.S.C. 1836(b) may not be commenced later than three years after the misappropriation is, or by reasonable diligence should be, discovered (18 U.S.C. 1836(d)).
A patent owner who waits loses damages: under 35 U.S.C. 286, no recovery may be had for infringement committed more than six years before the complaint. The patent itself lasts 20 years from filing (35 U.S.C. 154(a)(2)).
Do not assume that a state-law claim follows the federal deadlines. North Carolina’s limitation periods and the point when a claim accrues are matters of North Carolina statutes and case law, and an attorney can check the dates for your particular claim.

What to Do Before a Dispute Starts
The Lanham Act sets two routes to the principal register: use in commerce (15 U.S.C. 1051(a)(1)) and a bona fide intention to use (15 U.S.C. 1051(b)(1)). Each requires an application, a verified statement, and the prescribed fee.
In addition to the federal register, a business in North Carolina can file for a state trademark registration with the North Carolina Secretary of State (see the Trademark Registration Act, Article 1 of N.C. Gen. Stat. chapter 80). The state filing is a separate process from the federal application.
Owners of creative work should know that registration is a precondition to suing on a United States work (17 U.S.C. 411(a)), and that the duration for most later works is the life of the author plus 70 years (17 U.S.C. 302(a)).
Inventors should keep the 20-year term measured from filing in mind (35 U.S.C. 154(a)(2)), and should confirm early with an attorney that the invention falls within 35 U.S.C. 101.
Federal and State Courts for Intellectual Property Claims
Under 28 U.S.C. 1338(a), the federal district courts have original jurisdiction over patent, plant variety protection, copyright, and trademark claims, and that jurisdiction is exclusive for patents, plant variety protection, and copyrights. A trademark claim can also be brought in state court.
Under 28 U.S.C. 113, North Carolina’s counties are grouped into three federal districts. For New Hanover County, the court is the Eastern District of North Carolina, and it holds court in Elizabeth City, Fayetteville, Greenville, New Bern, Raleigh, Wilmington, and Wilson.
North Carolina Law Alongside Federal Law
The federal civil action for trade secrets (18 U.S.C. 1836(b)(1)) is filed in federal district court (18 U.S.C. 1836(c)), and a dispute from Wilmington may also raise a claim under the Trade Secrets Protection Act (N.C. Gen. Stat. 66-152 to 66-157). Which claims fit depends on the facts.
A brand owner in Wilmington may have state-law options in addition to federal ones. North Carolina’s trademark registration provisions are found in the Trademark Registration Act, Article 1 of N.C. Gen. Stat. chapter 80, and the filing office is the North Carolina Secretary of State.
The details of a state-law claim depend on the facts, and an attorney can explain which of the federal and state claims fit a particular dispute.
The Claims Behind Most Intellectual Property Disputes
Patent Claims and Defenses
The basic patent infringement rule is in 35 U.S.C. 271(a): without authority, making, using, offering to sell, or selling a patented invention in the United States, or importing one, during the patent term.
A patent case is filed in federal district court (28 U.S.C. 1338(a)).
Trademark Claims
Brand disputes often involve both a registered mark and one that has never been registered. Registered marks are protected against likely confusion under 15 U.S.C. 1114(1)(a), and 15 U.S.C. 1125(a)(1) covers false designation of origin more broadly.
A person who believes he or she is or is likely to be damaged can bring the civil action under 15 U.S.C. 1125(a)(1).
Disputes Over Writing, Images, Music, and Film
For writing, images, music, or film, copyright protects the original expression fixed in a tangible medium (17 U.S.C. 102(a)) but never the underlying idea (17 U.S.C. 102(b)).
For a United States work, registration must be made before an infringement suit is instituted (17 U.S.C. 411(a)).
Protecting Confidential Business Information
Trade secret cases often turn on whether the owner took reasonable measures to keep the information secret and whether it has independent economic value from not being generally known, the two elements of 18 U.S.C. 1839(3).
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
Damages, Injunctions, and Other Relief
Patent: a court that finds for the claimant shall award damages adequate to compensate for the infringement, but in no event less than a reasonable royalty for the use made of the invention, together with interest and costs, and the court may increase the damages up to three times the amount found or assessed (35 U.S.C. 284). Courts may also grant injunctions in accordance with the principles of equity to prevent the violation of a patent right (35 U.S.C. 283).
A brand owner who establishes a violation may recover the defendant’s profits, damages sustained, and costs (15 U.S.C. 1117(a)), and can ask the court for an injunction to stop the violation (15 U.S.C. 1116(a)), both subject to the principles of equity.
A copyright owner can choose between actual damages plus the infringer’s profits attributable to the infringement, and statutory damages (17 U.S.C. 504(a), (b)), and statutory damages range from $750 to $30,000 per work as the court considers just (17 U.S.C. 504(c)(1)).
Registering early matters for remedies as well as for suing: statutory damages and attorney’s fees are barred for infringement that began before registration, except when a published work is registered within three months after first publication (17 U.S.C. 412).
Trade secrets: under the federal statute a court may grant an injunction to prevent actual or threatened misappropriation, award damages for actual loss and for unjust enrichment, or impose liability for a reasonable royalty, and if the misappropriation was willful and malicious, award exemplary damages of not more than 2 times the damages awarded, and attorney’s fees in stated circumstances (18 U.S.C. 1836(b)(3)).
Protecting an idea, brand, or creative work in Wilmington? Talk to an attorney about your deadlines.
What to Gather Before You Talk to an Attorney
Start with the basics: what you created or invented, who was involved, and when each step happened. Dates matter because the deadlines described above run from events such as accrual of a claim, discovery of a misappropriation, or the filing of an application.
Patent matters go faster with drawings, lab notes, patent or application numbers, and a list of who has seen the invention. Trademark matters go faster with the mark itself, samples of its use, and any registration documents.
Copyright matters call for the original work, dated versions, registration papers, and side-by-side examples of the copying. Trade secret matters call for a description of the information, a list of who had access, and the confidentiality measures that existed.
