Your Mankato Intellectual Property Attorney
Intellectual property law splits into four main areas, patents, trademarks, copyrights, and trade secrets, and each has its own rules on where a case is filed and how long you have. The sections below explain those rules for a matter arising in Mankato. Keep reading for the deadlines, the registration steps for trademarks and copyrights, the court structure for Blue Earth, Le Sueur, and Nicollet counties, the trade secret rules, and the elements behind the most common infringement claims, citing the statute each time. 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
- 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)).
- Trademarks can be registered federally and in Minnesota. The federal register is set up by 15 U.S.C. 1051, and state registration is filed with the Minnesota Secretary of State under Minn. Stat. chapter 333.
- Three years to bring a copyright claim (17 U.S.C. 507(b)), and federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)).
- Minnesota has its own trade secret statute, the Uniform Trade Secrets Act (Minn. Stat. chapter 325C), and the federal action in 18 U.S.C. 1836 sits alongside it.
- A federal case from Mankato goes to the District of Minnesota (28 U.S.C. 103), which sits in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji.
What Patents, Trademarks, Copyrights, and Trade Secrets Protect
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 trademark identifies and distinguishes goods and their source. The statute defines it as any word, name, symbol, or device, or any combination, used by a person, or which a person has a bona fide intention to use in commerce and applies to register, to identify and distinguish that person’s goods from those manufactured or sold by others and to indicate the source (15 U.S.C. 1127). A service mark does the same for 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)).
Trade secret protection depends on two things: the owner took reasonable measures to keep the information secret, and the information has independent economic value because it is not generally known or readily ascertainable (18 U.S.C. 1839(3)). Formulas, methods, processes, programs, and codes can all qualify.
Time Limits That Matter in Patent, Copyright, and Trade Secret Cases
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.
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)).
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.
Do not assume that a state-law claim follows the federal deadlines. Minnesota’s limitation periods and the point when a claim accrues are matters of Minnesota statutes and case law, and an attorney can check the dates for your particular claim.

Registration Steps for Trademarks and Copyrights
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)).
Minnesota also has its own trademark registration. A state filing is made with the Minnesota Secretary of State under Minn. Stat. chapter 333, is separate from the federal register, and does not replace a federal application.
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)).
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 Mankato Is Filed
Patent, plant variety protection, and copyright claims belong exclusively in federal court: the district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents, plant variety protection, copyrights, and trademarks, and no state court may hear the patent, plant variety protection, and copyright claims (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court.
Minnesota constitutes one federal judicial district, the District of Minnesota (28 U.S.C. 103), so a federal case from Mankato is filed there. The court holds court in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji. Because Mankato lies in more than one county, it is worth confirming which county the matter falls in.
What Minnesota Law Can Add to Federal Protection
Minnesota has a trade secret statute of its own, the Uniform Trade Secrets Act (Minn. Stat. chapter 325C). A trade secret dispute from Mankato 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)).
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.
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.
Common Intellectual Property Claims
Patent Claims and Defenses
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.
Both patent owners and people accused of infringing should collect the patent number, product samples, and dates early.
Trademark 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.
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
Copyright Infringement
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)).
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)).
Protecting Confidential Business Information
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.
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
Damages, Injunctions, and Other Relief
Relief in a patent case can include damages of at least a reasonable royalty with interest and costs, and enhancement up to three times in the court’s discretion (35 U.S.C. 284), and an injunction on reasonable terms under the principles of equity (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)).
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)).
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.
Relief under 18 U.S.C. 1836(b)(3) includes an injunction, compensatory damages or a reasonable royalty, exemplary damages of up to 2 times for willful and malicious misappropriation, and reasonable attorney’s fees to the prevailing party when the statute’s conditions are met.

Preparing for a First Conversation
An attorney will usually begin with dates: creation, first disclosure, first use in commerce, first publication, and discovery of the problem. Gathering them ahead of time saves a first meeting for the questions that matter.
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.
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.

Frequently Asked Questions
What can be patented?
A new and useful process, machine, manufacture, or composition of matter may be patented, subject to the conditions and requirements of the patent statute (35 U.S.C. 101).
What is the difference between federal and Minnesota trademark registration?
Federal registration is on the principal register through the Patent and Trademark Office (15 U.S.C. 1051). Minnesota registration is a separate filing made with the Minnesota Secretary of State under Minn. Stat. chapter 333, and it does not replace the federal one.
Which court hears a copyright case from Mankato?
The federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)). For Mankato, that is the District of Minnesota.
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.
How many federal districts does Minnesota have?
Minnesota has one federal judicial district: the District of Minnesota (28 U.S.C. 103).
Can a trademark claim be brought under Minnesota law?
Possibly. Minnesota law may provide trademark claims of its own alongside the federal ones, and which apply depends on the mark and the facts. An attorney can explain the options.
When does the trade secret clock start?
From the date the misappropriation is discovered or, by reasonable diligence, should have been discovered (18 U.S.C. 1836(d)).
Can I protect a logo or slogan?
A word, name, symbol, or device used to identify and distinguish goods or services and indicate their source can be a trademark or service mark (15 U.S.C. 1127).
