Your Spearfish Intellectual Property Attorney
Ideas, brands, and creative work are only as protected as the steps taken to secure them and the speed of the response when someone copies them. If your business or work is based in Spearfish, the federal and South Dakota rules on patents, trademarks, copyrights, and trade secrets are written down, and knowing them early helps. Keep reading for the deadlines, the registration steps for trademarks and copyrights, the court structure for Lawrence County, the trade secret rules, and the elements behind the most common infringement claims, citing the statute each time. 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
- 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)).
- How long does a copyright last? For works created on or after January 1, 1978, the life of the author plus 70 years (17 U.S.C. 302(a)), with different counts for joint works and works made for hire.
- 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)).
- A federal case from Spearfish goes to the District of South Dakota (28 U.S.C. 122), which sits 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.
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)).
If the valuable thing is confidential know-how, the question is trade secret. Both elements in 18 U.S.C. 1839(3) must be present: reasonable measures to keep the information secret, and independent economic value from its not being generally known.
How Long Do You Have to Bring a Claim?
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)).
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).
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.

What to Do Before a Dispute Starts
For a trademark, the owner of a mark used in commerce may request registration on the principal register by paying the prescribed fee and filing an application and a verified statement with the Patent and Trademark Office (15 U.S.C. 1051(a)(1)). A person with a bona fide intention to use a mark in commerce may also apply (15 U.S.C. 1051(b)(1)).
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 Spearfish Is Filed
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.
South Dakota constitutes one federal judicial district, the District of South Dakota (28 U.S.C. 122), so a federal case from Spearfish is filed there. The court holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City.
What South Dakota Law Can Add to Federal Protection
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 Spearfish 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).
Whether to plead federal claims, state claims, or both turns on the facts, and an initial conversation with an attorney is the way to sort that out.
Types of Intellectual Property Claims
Using an Invention Without Permission
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.
Because the six-year damages limit in 35 U.S.C. 286 runs back from the complaint, delay can reduce what is recoverable.
Disputes Over Names, Logos, and Brands
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)).
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
Copyright Infringement
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).
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)).
Confidential Information and Departing Employees
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.
A continuing misappropriation is treated as a single claim for the federal deadline (18 U.S.C. 1836(d)).
What a Court Can Award or Order
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).
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: an infringer is liable for either the copyright owner’s actual damages and any additional profits of the infringer, or statutory damages (17 U.S.C. 504(a)). For statutory damages, the court may award a sum of not less than $750 or more than $30,000 per work as it considers just (17 U.S.C. 504(c)(1)).
Under 17 U.S.C. 412, an owner who registers after an infringement has started may lose access to statutory damages and attorney’s fees for that infringement, unless the work was published and registered within three months of first publication.
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
Bring a simple chronology. When was the work created, when was it first shared or sold, and when did you first notice the copying or use? Many of the deadlines on this page run from those events.
Patent matters go faster with drawings, lab notes, patent or application numbers, and a list of who has seen the invention. Trademark matters go faster with the mark itself, samples of its use, and any registration documents.
For a copyright question, bring the work, dated drafts, any registration papers, and examples of the copying. For a trade secret question, bring a description of the information, who had access, and what confidentiality steps were in place, such as agreements and access controls.
Spearfish: Courts, Counties, and Getting Started
The rules on this page are national or statewide, but the practical details are local. For a Spearfish claim that means Lawrence County and the District of South Dakota. Asking an attorney how long cases usually take there helps put the deadlines in context.

Frequently Asked Questions
How far back can I recover damages for patent infringement?
Six years before the complaint. No recovery may be had for infringement committed more than six years before the filing of the complaint (35 U.S.C. 286).
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.
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.
Do I have to file in federal court?
For patents and copyrights, yes: the federal jurisdiction is exclusive (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court, and a federal trade secret action is filed in federal district court (18 U.S.C. 1836(c)).
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.
What are the main deadlines in intellectual property cases?
Copyright: three years from accrual (17 U.S.C. 507(b)). Federal trade secrets: three years from discovery (18 U.S.C. 1836(d)). Patent damages: no recovery for infringement more than six years before the complaint (35 U.S.C. 286).
Can I protect software or written material?
Written material and other original expression fixed in a tangible medium can be protected by copyright (17 U.S.C. 102(a)), but not the underlying ideas, procedures, or methods of operation (17 U.S.C. 102(b)).
