Your Columbia Heights 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 Columbia Heights unfolds. This page covers the deadlines, the definitions that decide whether something is protected, the federal district court for Anoka County, and the Minnesota rules that sit next to the federal ones. An attorney who handles intellectual property matters can tell you which of these rules apply to your situation.
Your Key Federal and Minnesota 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)).
- 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)).
- Copyright covers expression, not ideas: original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), but never an idea, procedure, process, system, or method of operation (17 U.S.C. 102(b)).
- 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)).
- Where is my case filed? Columbia Heights is in the District of Minnesota, and that court holds court in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji (28 U.S.C. 103).
Four Kinds of Intellectual Property and What Each Covers
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)).
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.
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)).
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)).
Filing Deadlines and Damages Limits
Copyright: a civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)). Because a United States work must also be registered before an infringement suit can be filed (17 U.S.C. 411(a)), the registration step should not be left until after the dispute begins.
For a federal trade secret claim, the three years run from discovery of the misappropriation, or from when it should have been discovered by reasonable diligence, and a continuing misappropriation is treated as a single claim (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.
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.

Steps That Strengthen a Claim Before It Is Needed
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 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.
Copyright exists without a filing, but a lawsuit about a United States work requires preregistration or registration first (17 U.S.C. 411(a)). The standard term for a work created on or after January 1, 1978 is the life of the author and 70 years after the author’s death (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.
Federal and State Courts for Intellectual Property Claims
Federal law fixes the forum for most intellectual property claims: exclusive federal jurisdiction over patents and copyrights (28 U.S.C. 1338(a)), original federal jurisdiction over Defend Trade Secrets Act claims (18 U.S.C. 1836(c)), and concurrent state jurisdiction over trademarks.
The federal court for Columbia Heights is the District of Minnesota, which covers all of Minnesota (28 U.S.C. 103) and holds court in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji.
Minnesota Law Alongside Federal Law
Owners of confidential information in Columbia Heights can look to two sources: the Uniform Trade Secrets Act (Minn. Stat. chapter 325C) and the federal action in 18 U.S.C. 1836(b), which requires a connection to interstate or foreign commerce and has its own three-year deadline (18 U.S.C. 1836(d)).
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.
The Basics of Each Type of Claim
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.
Damages are limited to infringement within the six years before the complaint (35 U.S.C. 286).
Trademark and Unfair Competition Claims
Two federal provisions do most of the work in trademark cases: 15 U.S.C. 1114(1)(a) for registered marks and 15 U.S.C. 1125(a)(1) for misleading uses of any word, term, name, symbol, or device, registered or not.
Trademark claims may be filed in federal court or in state court (28 U.S.C. 1338(a)).
Copyright Claims
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)).
Disputes Over Trade Secrets
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)).
Documents showing who had access, and what confidentiality steps existed, are among the first things to preserve.
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).
Trademark: courts can grant injunctions according to the principles of equity to prevent the violation of the rights of a registrant or a violation of section 1125(a), (c), or (d) (15 U.S.C. 1116(a)), and when a violation is established the plaintiff is entitled, subject to the principles of equity, to recover the defendant’s profits, any damages sustained by the plaintiff, and the costs of the action (15 U.S.C. 1117(a)).
A copyright owner can choose between actual damages plus the infringer’s profits attributable to the infringement, and statutory damages (17 U.S.C. 504(a), (b)), and statutory damages range from $750 to $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).
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
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.
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.
Copyright matters call for the original work, dated versions, registration papers, and side-by-side examples of the copying. Trade secret matters call for a description of the information, a list of who had access, and the confidentiality measures that existed.
