Your Key Federal and South Dakota Rules in One Place
- Who can be liable for patent infringement? Anyone who, without authority, makes, uses, offers to sell, or sells a patented invention in the United States, or imports it (35 U.S.C. 271(a)).
- 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)).
- 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 Elk Point 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
If you have made something new and useful, such as a device, a process, a manufactured article, or a composition, a patent is the tool the statute provides (35 U.S.C. 101). The grant runs from issuance to 20 years after the application was filed (35 U.S.C. 154(a)(2)).
Under 15 U.S.C. 1127, a trademark is any word, name, symbol, or device, or a combination, that identifies and distinguishes one person’s goods from another’s and indicates their source, and a service mark performs that function for services.
Writing, music, images, film, software text, and similar creative work are the subject of copyright, which subsists in original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)). The statute is equally clear about what is excluded: ideas, procedures, processes, systems, methods of operation, concepts, principles, and discoveries (17 U.S.C. 102(b)).
A trade secret is information the owner has taken reasonable measures to keep secret and that derives independent economic value from not being generally known to, and not being readily ascertainable through proper means by, another person (18 U.S.C. 1839(3)). The statute covers financial, business, scientific, and technical information such as patterns, plans, formulas, designs, methods, processes, programs, and codes.
Why Timing Matters in Intellectual Property Disputes
Under 17 U.S.C. 507(b), a civil copyright action must be commenced within three years after the claim accrued, and under 17 U.S.C. 411(a) the copyright claim for a United States work must be registered, or registration refused, before that action is instituted.
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)).
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)).
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.

Steps That Strengthen a Claim Before It Is Needed
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 Elk Point Is Filed
The choice of court depends on the type of claim. Patent and copyright cases can only be filed in federal district court (28 U.S.C. 1338(a)), a federal trade secret action is filed in federal district court (18 U.S.C. 1836(c)), and trademark claims can go to federal or state court.
The federal court for Elk Point is the District of South Dakota, which covers all of South Dakota (28 U.S.C. 122) and holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City.
How South Dakota Law Fits In
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 Elk Point 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.
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).
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 Basics of Each Type of Claim
Claims That a Patent Is Being Infringed
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
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).
Copying of Creative Work
In a copyright case, the first questions are whether the work is protected at all under 17 U.S.C. 102(a) and whether what was copied was protected expression rather than an idea or method excluded by 17 U.S.C. 102(b).
Keeping dated copies of drafts and finished work helps show what was created and when.
Confidential Information and Departing Employees
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).
The Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11) may provide state-law claims alongside the federal action, with their own deadlines.
Remedies in Intellectual Property Cases
For patents, 35 U.S.C. 284 sets the damages floor at a reasonable royalty and lets the court increase damages up to three times the amount found or assessed, and 35 U.S.C. 283 allows injunctions according to the principles of equity, on terms the court considers reasonable.
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.
The registration date can decide whether statutory damages and attorney’s fees are available at all. Section 412 of the copyright statute bars them for infringement commenced before registration, subject to a three-month window after 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)).

Getting Your Records in Order
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.
If the issue is a patent, gather technical drawings, descriptions, and any application numbers. If it is a trademark, gather the mark, examples of use, and registration information.
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
Can a patent case be brought in South Dakota state court?
No. Patent claims are within the exclusive jurisdiction of the federal district courts (28 U.S.C. 1338(a)), so a case from Elk Point is filed in the District of South Dakota.
Can I register my business name or logo as a trademark?
A word, name, symbol, or device used to identify and distinguish goods and indicate their source is a trademark (15 U.S.C. 1127), and the owner of a mark used in commerce may request federal registration (15 U.S.C. 1051(a)(1)).
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.
What if a former employee took confidential information?
That can be a trade secret claim if the information meets the definition in 18 U.S.C. 1839(3), and the federal deadline is three years from discovery (18 U.S.C. 1836(d)). An attorney can review what was taken and what protections were in place.
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).
Can I register a trademark with the state of South Dakota?
Yes. A state registration is filed with the South Dakota Secretary of State under SDCL chapter 37-6, and it is a separate filing from the federal application.
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.
How do I know whether I need a patent, trademark, copyright, or trade secret protection?
It depends on what you are protecting: an invention (35 U.S.C. 101), a name or logo that identifies goods or services (15 U.S.C. 1127), original creative work (17 U.S.C. 102(a)), or confidential information (18 U.S.C. 1839(3)).
