The facts of your situation decide which area of law controls, and an attorney who practices in federal court can sort that out quickly.
Your Key Federal and South Dakota Rules in One Place
- 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)).
- How long does a copyright last? For works created on or after January 1, 1978, the life of the author plus 70 years (17 U.S.C. 302(a)), with different counts for joint works and works made for hire.
- 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? North Sioux City 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
Patents cover new and useful processes, machines, manufactures, and compositions of matter (35 U.S.C. 101). Protection lasts until 20 years after the date on which the application was filed in the United States (35 U.S.C. 154(a)(2)), so the filing date matters more than the date the patent issues.
If the issue is a business name, logo, or slogan, the question is trademark, which the Lanham Act defines as a word, name, symbol, or device that identifies and distinguishes goods and indicates their source (15 U.S.C. 1127), with service marks covering 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.
Filing Deadlines and Damages Limits
The copyright deadline is three years after the claim accrued (17 U.S.C. 507(b)). An owner who has not registered should treat registration as part of the first steps, since no infringement action on a United States work can be instituted before it (17 U.S.C. 411(a)).
Trade secret claims under federal law must be filed within three years of discovery, or of when reasonable diligence would have revealed the misappropriation, and continuing misappropriation is one claim (18 U.S.C. 1836(d)).
Patent infringement damages reach back at most six years before the complaint (35 U.S.C. 286), so a suspected infringement is worth reviewing promptly.
A South Dakota state-law claim brings its own deadline and its own accrual rule. Both come from South Dakota statutes and court decisions and should be reviewed by an attorney at the start of the matter.

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.
Copyright exists without a filing, but a lawsuit about a United States work requires preregistration or registration first (17 U.S.C. 411(a)). The standard term for a work created on or after January 1, 1978 is the life of the author and 70 years after the author’s death (17 U.S.C. 302(a)).
The application date controls the length of patent protection, which ends 20 years after filing (35 U.S.C. 154(a)(2)), so planning the filing is part of protecting the invention.
Where an Intellectual Property Case From North Sioux City Is Filed
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.
By statute the whole state is a single federal district (28 U.S.C. 122). A federal case from North Sioux City is filed in the District of South Dakota, where court is held at Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City.
What South Dakota Law Can Add to Federal Protection
Trade secret claims are not only federal. The Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11) may apply to the same facts, and the federal statute provides its own civil action when the secret relates to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)).
Trademark protection has a state layer as well. A state trademark registration in South Dakota is filed with the South Dakota Secretary of State under SDCL chapter 37-6, and it is separate from federal registration on the principal register (15 U.S.C. 1051).
Choosing between state and federal claims, or bringing both, is something an attorney should decide after reviewing what happened and what proof exists.
The Basics of Each Type of Claim
Claims That a Patent Is Being Infringed
Patent disputes turn on the patent’s claims and on conduct listed in 35 U.S.C. 271(a), namely making, using, offering to sell, selling, or importing a patented invention without authority.
Damages are limited to infringement within the six years before the complaint (35 U.S.C. 286).
Trademark and Unfair Competition Claims
Infringement of a registered mark means using in commerce a reproduction, counterfeit, copy, or colorable imitation of the mark in connection with the sale, offering for sale, distribution, or advertising of goods or services where the use is likely to cause confusion, mistake, or deception (15 U.S.C. 1114(1)(a)).
A state registration in South Dakota (SDCL chapter 37-6) is different from federal registration on the principal register (15 U.S.C. 1051).
Copyright Infringement
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)).
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
Disputes Over Trade Secrets
The Defend Trade Secrets Act lets the owner of a misappropriated trade secret sue when the secret relates to a product or service in interstate or foreign commerce (18 U.S.C. 1836(b)(1)). Whether the information qualifies depends on the definition in 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).
The trademark remedies are set out in 15 U.S.C. 1116(a), which gives courts the power to grant injunctions, and 15 U.S.C. 1117(a), which lets a plaintiff recover defendant’s profits, damages, and costs once a violation is established.
The copyright statute offers two routes to money relief: actual damages and profits (17 U.S.C. 504(b)) or statutory damages of not less than $750 or more than $30,000 for infringements of any one work (17 U.S.C. 504(c)(1)).
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.
The Defend Trade Secrets Act lists the remedies: an injunction, damages for actual loss and unjust enrichment (or a reasonable royalty), exemplary damages of not more than 2 times the damages for willful and malicious misappropriation, and attorney’s fees in the situations the statute names (18 U.S.C. 1836(b)(3)).

Preparing for a First Conversation
Write down a short timeline before the call: when the work or invention was made, when it was first shown to anyone, and when you learned of the problem. The federal deadlines above are measured from dates like these.
Useful patent records include sketches, notebooks, prototypes, and application numbers. Useful trademark records include the logo or name, packaging or signage showing use, and state or federal registration papers.
For a copyright question, bring the work, dated drafts, any registration papers, and examples of the copying. For a trade secret question, bring a description of the information, who had access, and what confidentiality steps were in place, such as agreements and access controls.

Frequently Asked Questions
How long does a patent last?
A patent lasts 20 years from the date the application was filed in the United States (35 U.S.C. 154(a)(2)), so the filing date, not the issue date, sets the end of the term.
Can a trademark case be filed in state court?
Yes. The federal district courts have original jurisdiction over trademark claims, and trademark claims may also be brought in state court (28 U.S.C. 1338(a)).
Do I have to register a copyright before I sue?
For a United States work, yes. No civil action for infringement of the copyright may be instituted until preregistration or registration of the copyright claim has been made (17 U.S.C. 411(a)), with a provision for cases where registration was refused.
What do I have to show to protect a trade secret?
The two elements of the definition: that you took reasonable measures to keep the information secret, and that it has independent economic value from not being generally known or readily ascertainable (18 U.S.C. 1839(3)).
Which federal court covers North Sioux City?
The District of South Dakota (28 U.S.C. 122).
Can a trademark claim be brought under South Dakota law?
Possibly. South Dakota law may provide trademark claims of its own alongside the federal ones, and which apply depends on the mark and the facts. An attorney can explain the options.
Is there a deadline to sue for patent infringement?
Patent damages reach back six years before the complaint (35 U.S.C. 286), so delay can reduce recovery even while the patent is in force.
Can I protect software or written material?
Written material and other original expression fixed in a tangible medium can be protected by copyright (17 U.S.C. 102(a)), but not the underlying ideas, procedures, or methods of operation (17 U.S.C. 102(b)).
