Your Rosemount 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 Minnesota rules that most often decide how an intellectual property matter from Rosemount unfolds. You will find the quick answers first, then the definitions, deadlines, registration, the courts, state law, and the basic elements of infringement claims, with the statute behind each point. These rules apply across Minnesota, and an attorney familiar with the District of Minnesota can explain what to expect there.
Deadlines and Courts: The Short Version
- A patent case is a federal case. The district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents (28 U.S.C. 1338(a)), and infringement damages are limited to the six years before the complaint (35 U.S.C. 286).
- Federal trademark registration is available to the owner of a mark used in commerce or to a person with a bona fide intention to use one (15 U.S.C. 1051(a)(1), (b)(1)).
- 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)).
- 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)).
- A federal case from Rosemount goes to the District of Minnesota (28 U.S.C. 103), which sits in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji.
The Four Main Areas of Intellectual Property Law
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.
Copyright protects original works of authorship fixed in any tangible medium of expression (17 U.S.C. 102(a)), such as literary, musical, dramatic, and pictorial works, motion pictures, sound recordings, and architectural works. It never extends to an idea, procedure, process, system, method of operation, concept, principle, or discovery (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.
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.
The federal trade secret deadline is set by 18 U.S.C. 1836(d): three years from the date the misappropriation was discovered or by the exercise of reasonable diligence should have been discovered, with continuing misappropriation counted as one claim.
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 Minnesota 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.

Registering and Protecting Your Rights
Registration on the federal principal register begins with an application and verified statement. The statute allows the owner of a mark used in commerce to apply (15 U.S.C. 1051(a)(1)) and separately a person with a bona fide intention to use (15 U.S.C. 1051(b)(1)).
State registration is a different filing from a federal application. In Minnesota it is made with the Minnesota Secretary of State under Minn. Stat. chapter 333, and an attorney can tell you whether a state filing, a federal filing, or both suit your plans.
Registering a copyright before there is a dispute avoids a delay later. The statute says no civil action for infringement of the copyright in a United States work may be instituted until preregistration or registration has been made (17 U.S.C. 411(a)).
For an invention, the patent term of 20 years runs from the date the application was filed (35 U.S.C. 154(a)(2)), so the timing of an application is worth discussing with a patent attorney.
Federal District Courts and Where They Sit
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. 103, Minnesota is one federal judicial district, and Dakota County is part of it. The District of Minnesota holds court in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji.
Minnesota Law Alongside Federal Law
A misappropriated trade secret can support a federal claim under 18 U.S.C. 1836(b) when it is connected to interstate or foreign commerce, and it may also support a claim under the Uniform Trade Secrets Act (Minn. Stat. chapter 325C). The state and federal claims are separate.
Federal trademark law under 15 U.S.C. 1114 and 1125 sits alongside Minnesota’s registration system, which runs through the Minnesota Secretary of State under Minn. Stat. chapter 333. The two operate separately.
Which claims to bring, and in which court, is a strategy question for an attorney who can read the documents.
Common Intellectual Property Claims
Patent Disputes
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.
A patent case is filed in federal district court (28 U.S.C. 1338(a)).
Trademark Claims
Brand disputes often involve both a registered mark and one that has never been registered. Registered marks are protected against likely confusion under 15 U.S.C. 1114(1)(a), and 15 U.S.C. 1125(a)(1) covers false designation of origin more broadly.
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)).
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.
Documents showing who had access, and what confidentiality steps existed, are among the first things to preserve.
Remedies in Intellectual Property Cases
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).
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.
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)).
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.
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)).

Getting Your Records in Order
Write down a short timeline before the call: when the work or invention was made, when it was first shown to anyone, and when you learned of the problem. The federal deadlines above are measured from dates like these.
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.

Frequently Asked Questions
What counts as patent infringement?
Without authority, making, using, offering to sell, or selling a patented invention in the United States, or importing one into the United States, during the term of the patent (35 U.S.C. 271(a)).
Can I register a trademark before I start using it?
Yes, in one way: a person with a bona fide intention, under circumstances showing good faith, to use a trademark in commerce may request registration on the principal register (15 U.S.C. 1051(b)(1)).
How long do I have to sue for copyright infringement?
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
Can I sue in federal court over a stolen trade secret?
Yes, if the trade secret is related to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)). The federal district courts have original jurisdiction of these actions (18 U.S.C. 1836(c)).
Are trade secret cases filed in federal court?
A federal trade secret action under 18 U.S.C. 1836 is filed in federal district court (18 U.S.C. 1836(c)), and Minnesota state-law claims are separate claims.
Does Minnesota law protect trade secrets?
Yes. Minnesota has the Uniform Trade Secrets Act (Minn. Stat. chapter 325C), and the federal Defend Trade Secrets Act (18 U.S.C. 1836) adds a separate federal action.
Is there a deadline to sue for patent infringement?
Patent damages reach back six years before the complaint (35 U.S.C. 286), so delay can reduce recovery even while the patent is in force.
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)).
