Your Custer 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 Custer business, artist, or inventor, the first step is knowing which one is actually involved, and this page walks through how to tell. This page covers the deadlines, the definitions that decide whether something is protected, the federal district court for Custer County, and the South Dakota rules that sit next to the federal ones. Deadlines in intellectual property cases run on fixed dates, so learning them early usually helps more than trying to catch up later.
Your Key Federal and South Dakota Rules in One Place
- 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).
- 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)).
- 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? Custer 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).
The Four Main Areas of Intellectual Property Law
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)).
Why Timing Matters in Intellectual Property Disputes
Three years is the copyright limit in 17 U.S.C. 507(b), measured from when the claim accrued. Registration comes first under 17 U.S.C. 411(a), so the clock and the registration process can overlap.
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)).
Do not assume that a state-law claim follows the federal deadlines. South Dakota’s limitation periods and the point when a claim accrues are matters of South Dakota statutes and case law, and an attorney can check the dates for your particular claim.

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.
For copyright, protection attaches to original works fixed in a tangible medium (17 U.S.C. 102(a)), but before an infringement suit on a United States work can be instituted, preregistration or registration of the copyright claim must have been made (17 U.S.C. 411(a)). A work created on or after January 1, 1978 lasts for the life of the author plus 70 years (17 U.S.C. 302(a)).
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.
Which Court Handles a Claim From Custer
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.
There is only one federal district in South Dakota. The District of South Dakota hears federal cases from Custer County and holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City (28 U.S.C. 122).
What South Dakota Law Can Add to Federal Protection
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 Custer 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)).
A state trademark registration in South Dakota is a different filing from federal registration (15 U.S.C. 1051). It is made with the South Dakota Secretary of State under SDCL chapter 37-6.
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
Patent Claims and Defenses
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.
Both patent owners and people accused of infringing should collect the patent number, product samples, and dates early.
Trademark and Unfair Competition Claims
Even without registration, the Lanham Act allows a civil action against anyone who uses in commerce a word, term, name, symbol, or device likely to cause confusion or deceive about affiliation, connection, or origin (15 U.S.C. 1125(a)(1)), brought by a person who believes he or she is or is likely to be damaged.
Trademark claims may be filed in federal court or in state court (28 U.S.C. 1338(a)).
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)).
Trade Secret Claims
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)).
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).
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.
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)).
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
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.
Inventors should collect drawings, notes, and application numbers, and brand owners should collect the mark, examples of use, and any registration papers, before the first conversation.
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.
