If you are trying to protect an invention, a brand, or a creative work in Garretson, or you have been accused of infringing someone else’s, you probably want plain answers about deadlines, courts, and what each kind of protection covers. Federal statutes set most of them, so many answers can be checked. Below you will find the key deadlines at a glance, what each type of protection covers, the steps that come before a lawsuit, which federal court hears a case from Minnehaha County, and how South Dakota law fits alongside federal law. 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
- A patent case is a federal case. The district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents (28 U.S.C. 1338(a)), and infringement damages are limited to the 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)).
- 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)).
- Trade secrets get a federal 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)), filed in federal district court (18 U.S.C. 1836(c)).
- A federal case from Garretson goes to the District of South Dakota (28 U.S.C. 122), which sits in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City.
Four Kinds of Intellectual Property and What Each Covers
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)).
A brand is protected as a trademark when it functions to identify and distinguish goods from those of others and to indicate the source of the goods (15 U.S.C. 1127). The same statute defines a service mark for the source of services.
A copyright question begins with whether the work is an original work of authorship fixed in a tangible medium (17 U.S.C. 102(a)) and whether what was copied was expression rather than an idea, system, or method (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)).
Filing Deadlines and Damages Limits
For copyright infringement, the statute sets three years from when the claim accrued (17 U.S.C. 507(b)), and registration or a refusal of registration must come before suit on a United States work (17 U.S.C. 411(a)).
Trade secrets: a federal action under the Defend Trade Secrets Act may not be commenced later than 3 years after the misappropriation is discovered or, with reasonable diligence, should have been discovered, and a continuing misappropriation counts as a single claim (18 U.S.C. 1836(d)).
For patent damages, the look-back is six years from the complaint (35 U.S.C. 286), which is separate from the 20-year patent term measured from the filing date (35 U.S.C. 154(a)(2)).
The federal deadlines above do not decide state-law claims. South Dakota sets its own limitation periods and accrual rules, and an attorney can tell you which apply to a trade secret or unfair competition claim brought under state law.

Registering and Protecting Your Rights
A business planning a brand can file for federal registration based on actual use in commerce (15 U.S.C. 1051(a)(1)) or based on a bona fide intention to use it (15 U.S.C. 1051(b)(1)).
A South Dakota business can ask an attorney whether a state-level trademark filing with the South Dakota Secretary of State is worth adding to a federal application. The provisions are in SDCL chapter 37-6, and the two registrations are separate.
A copyright owner cannot file an infringement action on a United States work before registration has been made (17 U.S.C. 411(a)), although a refusal of registration can also open the door to suit if the Register of Copyrights is notified and served with the complaint.
The filing date is what starts the patent clock (35 U.S.C. 154(a)(2)), so the timing of an application matters. An attorney can advise whether the invention fits the categories in 35 U.S.C. 101.
Federal and State Courts for Intellectual Property Claims
In practice, patent and copyright disputes are filed in federal district court (28 U.S.C. 1338(a)), federal trade secret claims start there as well (18 U.S.C. 1836(c)), and a trademark dispute can be filed in federal or state court.
There is only one federal district in South Dakota. The District of South Dakota hears federal cases from Minnehaha County and holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City (28 U.S.C. 122).
State-Law Rules for Trademarks and Trade Secrets
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 Garretson may also raise a claim under the Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11). Which claims fit depends on the facts.
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.

Common Intellectual Property Claims
Using an Invention Without Permission
A patent claim asks whether the accused product or process is covered by the patent and whether the accused party acted without authority. The forms of infringement listed in 35 U.S.C. 271(a) are making, using, offering to sell, selling, and importing.
The patent term is 20 years from the filing date (35 U.S.C. 154(a)(2)), so a case about an expired patent is limited to past infringement.
Trademark Infringement and Brand Disputes
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).
Copying of 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)).
The duration of a copyright for a work created on or after January 1, 1978 is generally the life of the author plus 70 years (17 U.S.C. 302(a)).
Protecting Confidential Business Information
A federal trade secret claim requires a trade secret related to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)), and the information must meet the definition of a trade secret in 18 U.S.C. 1839(3): reasonable secrecy measures and independent economic value.
The federal action has a three-year deadline running from discovery, or from when reasonable diligence should have led to discovery (18 U.S.C. 1836(d)).
Remedies in Intellectual Property Cases
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.
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.
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)).

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.
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.
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.

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 Garretson, 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 does a copyright last?
For a work created on or after January 1, 1978, the life of the author and 70 years after the author’s death (17 U.S.C. 302(a)), with different rules for joint works, anonymous and pseudonymous works, and works made for hire.
Can I sue in federal court over a stolen trade secret?
Yes, if the trade secret is related to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)). The federal district courts have original jurisdiction of these actions (18 U.S.C. 1836(c)).
How many federal districts does South Dakota have?
South Dakota has one federal judicial district: the District of South Dakota (28 U.S.C. 122).
Do federal deadlines apply to South Dakota state-law claims?
Not automatically. South Dakota state-law claims have their own limitation periods and accrual rules, set by South Dakota statutes and court decisions, and an attorney should check them.
When does the trade secret clock start?
From the date the misappropriation is discovered or, by reasonable diligence, should have been discovered (18 U.S.C. 1836(d)).
How do I keep information as a trade secret?
Take reasonable measures to keep it secret, because that is one of the two elements of the definition (18 U.S.C. 1839(3)), and consult an attorney about what measures are reasonable for your business.
