Your Winner 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 South Dakota rules that most often decide how an intellectual property matter from Winner unfolds. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for Tripp County, South Dakota’s own trademark and trade secret rules, and what an infringement claim involves. Deadlines in intellectual property cases run on fixed dates, so learning them early usually helps more than trying to catch up later.
The Short Answers: Deadlines, Courts, and Protection
- Patent claims are filed in federal court only (28 U.S.C. 1338(a)), and the six-year damages limit in 35 U.S.C. 286 makes early action important.
- Trademark claims can go to federal or state court (28 U.S.C. 1338(a)), and South Dakota’s own registration is a separate filing with the South Dakota Secretary of State.
- Register first, sue second. No civil action for infringement of the copyright in a United States work can be instituted until registration has been made or refused in the way the statute provides (17 U.S.C. 411(a)).
- What is a trade secret? Information the owner has taken reasonable measures to keep secret and that derives independent economic value from not being generally known (18 U.S.C. 1839(3)).
- Federal district: for Tripp County, the District of South Dakota under 28 U.S.C. 122, holding court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City.
Which Type of Protection Fits Your Situation
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 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.
Copyright protects expression, not ideas. The subject matter is original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and protection does not extend to any idea, procedure, process, system, or method of operation, however it is described (17 U.S.C. 102(b)).
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
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.
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)).
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.
State-law claims, such as a claim under the Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11) or a state trademark claim, have their own rules on limitation periods and on when a claim begins to run. Those are set by South Dakota statutes and court decisions, so the dates should be checked by an attorney rather than assumed from the federal deadlines.

Registering and Protecting Your Rights
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.
Federal registration is not the only route. South Dakota’s trademark registration provisions, SDCL chapter 37-6, provide for a state filing with the South Dakota Secretary of State that operates separately from the federal register.
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)).
A patent application starts the 20-year term (35 U.S.C. 154(a)(2)), and the invention must fit a statutory category such as a process, machine, manufacture, or composition of matter (35 U.S.C. 101). An attorney can review both points before you file.
Where an Intellectual Property Case From Winner 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 Winner 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.
State-Law Rules for Trademarks and Trade Secrets
South Dakota has a trade secret statute of its own, the Uniform Trade Secrets Act (SDCL 37-29-1 to 37-29-11). A trade secret dispute from Winner can involve that statute, and the federal Defend Trade Secrets Act adds a civil action in federal court for a trade secret related to a product or service used in interstate or foreign commerce (18 U.S.C. 1836(b)(1), (c)).
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.
The Claims Behind Most Intellectual Property Disputes
Using an Invention Without Permission
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.
Damages are limited to infringement within the six years before the complaint (35 U.S.C. 286).
Confusing Similarity and Brand Protection
For a registered mark, the core question is whether the defendant’s use of a reproduction, copy, counterfeit, or colorable imitation is likely to cause confusion, mistake, or deception in connection with goods or services (15 U.S.C. 1114(1)(a)).
Trademark claims may be filed in federal court or in state court (28 U.S.C. 1338(a)).
Copyright Infringement
Creative disputes involve two threshold points: the work must be an original work of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and the claim cannot rest on an idea or system (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)).
Protecting Confidential Business Information
The federal claim in 18 U.S.C. 1836(b)(1) is limited to trade secrets connected to interstate or foreign commerce, and the information must satisfy 18 U.S.C. 1839(3) to count as a trade secret at all.
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)).
What a Successful Claim Can Recover
The patent statute provides for damages adequate to compensate for the infringement, not less than a reasonable royalty (35 U.S.C. 284), and for injunctions to prevent the violation of a patent right (35 U.S.C. 283).
For trademark violations, the Lanham Act allows injunctions on terms the court considers reasonable (15 U.S.C. 1116(a)) and allows recovery, subject to equity, of the defendant’s profits, the plaintiff’s damages, and the costs of the action (15 U.S.C. 1117(a)).
Copyright damages can be measured by the owner’s actual damages and the infringer’s attributable profits (17 U.S.C. 504(b)), or by statutory damages between $750 and $30,000 per work as the court considers just (17 U.S.C. 504(c)(1)).
Registration timing affects these remedies: no award of statutory damages or attorney’s fees is available for infringement of an unpublished work commenced before the effective date of its registration, or for infringement commenced after first publication and before registration unless registration is made within three months after first publication (17 U.S.C. 412).
Relief under 18 U.S.C. 1836(b)(3) includes an injunction, compensatory damages or a reasonable royalty, exemplary damages of up to 2 times for willful and malicious misappropriation, and reasonable attorney’s fees to the prevailing party when the statute’s conditions are met.

Documents and Dates That Help
Before you talk to anyone, list the key dates in order. Copyright and federal trade secret deadlines run from accrual and discovery, and patent damages look back from the complaint, so a clean timeline shows where you stand.
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.
Creators should bring the work itself, dated drafts, and examples of the copy. Owners of confidential information should bring a description of it, a list of who had access, and the steps taken to keep it secret.

Frequently Asked Questions
What can be patented?
A new and useful process, machine, manufacture, or composition of matter may be patented, subject to the conditions and requirements of the patent statute (35 U.S.C. 101).
Does an unregistered brand have any protection?
Possibly. A civil action can be brought under 15 U.S.C. 1125(a)(1) by a person who believes he or she is or is likely to be damaged by a false designation of origin likely to cause confusion, and South Dakota law may offer additional protection.
What kinds of work does copyright cover?
Original works of authorship fixed in any tangible medium of expression (17 U.S.C. 102(a)), including literary, musical, dramatic, and pictorial works, motion pictures, sound recordings, and architectural works.
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.
Which federal court covers Winner?
The District of South Dakota (28 U.S.C. 122).
Does state registration replace federal registration?
No. A state registration, where one is available, is a separate filing from federal registration on the principal register (15 U.S.C. 1051), and each operates on its own.
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)).
Can I protect a business idea?
An idea by itself is not protected by copyright (17 U.S.C. 102(b)). An invention that fits a category in 35 U.S.C. 101 may be patentable, and confidential business information may qualify as a trade secret (18 U.S.C. 1839(3)).
