Your Key Federal and South Dakota Rules in One Place
- 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.
- Copyright lawsuits have a three-year clock from when the claim accrued (17 U.S.C. 507(b)), and a United States work must be registered before an infringement suit can be filed (17 U.S.C. 411(a)).
- Federal trade secret claims must be brought within 3 years after the misappropriation is discovered or should have been discovered with reasonable diligence (18 U.S.C. 1836(d)).
- Which court? A case from Eagle Butte that belongs in federal court is filed in the District of South Dakota, which holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City.
Patents, Trademarks, Copyrights, and Trade Secrets Compared
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.
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)).
Business and technical information such as plans, formulas, and processes qualifies as a trade secret only if the owner has taken reasonable measures to keep it secret and it derives independent economic value from secrecy (18 U.S.C. 1839(3)).
Deadlines for Intellectual Property Claims
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 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)).
Six years is the number to know in patent cases: infringement more than six years before the complaint cannot be recovered on (35 U.S.C. 286).
Claims under South Dakota law carry their own limitation periods and their own rules for when the clock starts, which are different questions from the federal deadlines in this section. Have the dates checked before relying on any of them.

What to Do Before a Dispute Starts
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.
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)).
Inventors should keep the 20-year term measured from filing in mind (35 U.S.C. 154(a)(2)), and should confirm early with an attorney that the invention falls within 35 U.S.C. 101.
Where an Intellectual Property Case From Eagle Butte Is Filed
Under 28 U.S.C. 1338(a), the federal district courts have original jurisdiction over patent, plant variety protection, copyright, and trademark claims, and that jurisdiction is exclusive for patents, plant variety protection, and copyrights. A trademark claim can also be brought in state court.
Under 28 U.S.C. 122, South Dakota is one federal judicial district, and Dewey and Ziebach counties is part of it. The District of South Dakota holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City. Because Eagle Butte lies in more than one county, it is worth confirming which county the matter falls in.
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 Eagle Butte 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).
Which claims to bring, and in which court, is a strategy question for an attorney who can read the documents.
What Kinds of Intellectual Property Cases Come Up?
Patent Infringement
Whether conduct is infringement is measured against 35 U.S.C. 271(a), which reaches anyone who, without authority, makes, uses, offers to sell, or sells a patented invention in the United States or imports it during the patent’s term.
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 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)).
Disputes Over Writing, Images, Music, and Film
Whether copying is actionable begins with what is protected. Copyright subsists in original works fixed in a tangible medium (17 U.S.C. 102(a)) and does not reach ideas, procedures, processes, systems, or methods of operation (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
In a trade secret dispute, both sides examine the same two things: the steps the owner took to keep the information secret and the value that comes from its not being generally known or readily ascertainable (18 U.S.C. 1839(3)).
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
What a Successful Claim Can Recover
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.
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.
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.
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)).

What to Gather Before You Talk to an Attorney
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.
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.
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.
