Your Pierre Intellectual Property Attorney
A patent, a trademark, a copyright, and a trade secret are four different things with four different sets of rules. For a Pierre business, artist, or inventor, the first step is knowing which one is actually involved, and this page walks through how to tell. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for Hughes County, South Dakota’s own trademark and trade secret rules, and what an infringement claim involves. These rules apply across South Dakota, and an attorney familiar with the District of South Dakota can explain what to expect there.
Deadlines and Courts: The Short Version
- Patents belong in federal court. Federal district courts have original jurisdiction over patent claims (28 U.S.C. 1338(a)), and damages cannot reach back more than six years before the complaint (35 U.S.C. 286).
- Even an unregistered mark can be protected against false designation of origin, through a civil action by anyone who believes they are likely to be damaged (15 U.S.C. 1125(a)(1)).
- Copyright covers expression, not ideas: original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), but never an idea, procedure, process, system, or method of operation (17 U.S.C. 102(b)).
- South Dakota has its own trade secret statute, the Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11), and the federal action in 18 U.S.C. 1836 sits alongside it.
- Where is my case filed? Pierre is in the District of South Dakota, and that court holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City (28 U.S.C. 122).
What Patents, Trademarks, Copyrights, and Trade Secrets Protect
Inventions are the domain of patent law. The categories the statute names are processes, machines, manufactures, and compositions of matter (35 U.S.C. 101), and the patent term ends 20 years from the filing date of the application (35 U.S.C. 154(a)(2)).
A trademark identifies and distinguishes goods and their source. The statute defines it as any word, name, symbol, or device, or any combination, used by a person, or which a person has a bona fide intention to use in commerce and applies to register, to identify and distinguish that person’s goods from those manufactured or sold by others and to indicate the source (15 U.S.C. 1127). A service mark does the same for services.
Copyright protects original works of authorship fixed in any tangible medium of expression (17 U.S.C. 102(a)), such as literary, musical, dramatic, and pictorial works, motion pictures, sound recordings, and architectural works. It never extends to an idea, procedure, process, system, method of operation, concept, principle, or discovery (17 U.S.C. 102(b)).
Unlike a patent, a trade secret is kept private. The federal definition requires reasonable secrecy measures and independent economic value from not being generally known or readily ascertainable through proper means (18 U.S.C. 1839(3)).
How Long Do You Have to Bring a Claim?
Copyright: a civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)). Because a United States work must also be registered before an infringement suit can be filed (17 U.S.C. 411(a)), the registration step should not be left until after the dispute begins.
For a federal trade secret claim, the three years run from discovery of the misappropriation, or from when it should have been discovered by reasonable diligence, and a continuing misappropriation is treated as a single claim (18 U.S.C. 1836(d)).
Patents: there is no recovery for infringement committed more than six years before the filing of the complaint or counterclaim for infringement (35 U.S.C. 286). Waiting can therefore shrink the damages available even when the patent itself is still in force.
Claims under South Dakota law carry their own limitation periods and their own rules for when the clock starts, which are different questions from the federal deadlines in this section. Have the dates checked before relying on any of them.

What to Do Before a Dispute Starts
Federal trademark registration is available both to owners of a mark already used in commerce (15 U.S.C. 1051(a)(1)) and to a person with a bona fide intention, in good faith, to use a mark in commerce (15 U.S.C. 1051(b)(1)), through an application and a verified statement filed with the Patent and Trademark Office.
State registration is a different filing from a federal application. In South Dakota it is made with the South Dakota Secretary of State under SDCL chapter 37-6, and an attorney can tell you whether a state filing, a federal filing, or both suit your plans.
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)).
For an invention, the patent term of 20 years runs from the date the application was filed (35 U.S.C. 154(a)(2)), so the timing of an application is worth discussing with a patent attorney.
Federal District Courts and Where They Sit
Patent, plant variety protection, and copyright claims belong exclusively in federal court: the district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents, plant variety protection, copyrights, and trademarks, and no state court may hear the patent, plant variety protection, and copyright claims (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court.
There is only one federal district in South Dakota. The District of South Dakota hears federal cases from Hughes County and holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City (28 U.S.C. 122).
South Dakota Law Alongside Federal Law
Owners of confidential information in Pierre can look to two sources: the Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11) and the federal action in 18 U.S.C. 1836(b), which requires a connection to interstate or foreign commerce and has its own three-year deadline (18 U.S.C. 1836(d)).
Federal trademark law under 15 U.S.C. 1114 and 1125 sits alongside South Dakota’s registration system, which runs through the South Dakota Secretary of State under SDCL chapter 37-6. The two operate separately.
Which claims to bring, and in which court, is a strategy question for an attorney who can read the documents.
Types of Intellectual Property Claims
Using an Invention Without Permission
Infringement occurs when someone, without authority, makes, uses, offers to sell, or sells any patented invention within the United States, or imports a patented invention into the United States, during the term of the patent (35 U.S.C. 271(a)).
Damages are limited to infringement within the six years before the complaint (35 U.S.C. 286).
Trademark Infringement and Brand Disputes
Two federal provisions do most of the work in trademark cases: 15 U.S.C. 1114(1)(a) for registered marks and 15 U.S.C. 1125(a)(1) for misleading uses of any word, term, name, symbol, or device, registered or not.
A state registration in South Dakota (SDCL chapter 37-6) is different from federal registration on the principal register (15 U.S.C. 1051).
Protecting Creative Work
A copyright claim starts with an original work of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and it is limited to expression: the idea, procedure, process, system, or method of operation is not protected (17 U.S.C. 102(b)).
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
Confidential Information and Departing Employees
In a trade secret dispute, both sides examine the same two things: the steps the owner took to keep the information secret and the value that comes from its not being generally known or readily ascertainable (18 U.S.C. 1839(3)).
A continuing misappropriation is treated as a single claim for the federal deadline (18 U.S.C. 1836(d)).
Injunctions and Money Damages by Type of Claim
Relief in a patent case can include damages of at least a reasonable royalty with interest and costs, and enhancement up to three times in the court’s discretion (35 U.S.C. 284), and an injunction on reasonable terms under the principles of equity (35 U.S.C. 283).
In trademark cases, courts have the power to enjoin violations (15 U.S.C. 1116(a)), and a plaintiff who establishes a violation may recover profits, damages, and costs, subject to sections 1111 and 1114 and the principles of equity (15 U.S.C. 1117(a)).
Under 17 U.S.C. 504, the choice is between actual damages with additional profits and statutory damages, which the court sets between $750 and $30,000 for any one work.
Under 17 U.S.C. 412, an owner who registers after an infringement has started may lose access to statutory damages and attorney’s fees for that infringement, unless the work was published and registered within three months of first publication.
In federal trade secret cases the court can enjoin actual or threatened misappropriation, award damages for loss and unjust enrichment or a reasonable royalty, and, for willful and malicious misappropriation, exemplary damages up to 2 times the damages awarded (18 U.S.C. 1836(b)(3)).

Preparing for a First Conversation
An attorney will usually begin with dates: creation, first disclosure, first use in commerce, first publication, and discovery of the problem. Gathering them ahead of time saves a first meeting for the questions that matter.
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.
Bring the original work and dated drafts for a copyright issue, and a description of the information, access records, and confidentiality measures for a trade secret issue.
A Note on Pierre and the Federal Court
The rules on this page are national or statewide, but the practical details are local. For a Pierre claim that means Hughes County and the District of South Dakota. Asking an attorney how long cases usually take there helps put the deadlines in context.

Frequently Asked Questions
Where is a patent infringement case filed?
In federal district court. The district courts have original jurisdiction of civil actions arising under patent law, and that jurisdiction is exclusive (28 U.S.C. 1338(a)). For Pierre, that is the District of South Dakota.
What is trademark infringement?
For a registered mark, it is using in commerce a reproduction, counterfeit, copy, or colorable imitation in connection with goods or services where the use is likely to cause confusion, mistake, or deception (15 U.S.C. 1114(1)(a)).
How long do I have to sue for copyright infringement?
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
Does South Dakota have a trade secret statute?
Yes. It is the Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11). The federal Defend Trade Secrets Act provides a separate civil action (18 U.S.C. 1836), and an attorney can tell you which claims fit the facts.
Do I have to file in federal court?
For patents and copyrights, yes: the federal jurisdiction is exclusive (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court, and a federal trade secret action is filed in federal district court (18 U.S.C. 1836(c)).
Can I bring both federal and South Dakota claims?
Often yes. A dispute can involve federal claims, such as under 15 U.S.C. 1114 or 18 U.S.C. 1836, and state-law claims under South Dakota law. An attorney can advise which to bring.
Why does timing matter in an intellectual property dispute?
Because federal statutes set fixed limits, such as three years for copyright (17 U.S.C. 507(b)) and for federal trade secret claims (18 U.S.C. 1836(d)), and six years of look-back for patent damages (35 U.S.C. 286), waiting can cost rights and money.
What should I do if someone copies my work?
Note the dates, keep copies, and speak with an attorney early, since deadlines such as three years for copyright (17 U.S.C. 507(b)) and six years of look-back for patent damages (35 U.S.C. 286) run from the events.
