Quick Answers on Patents, Trademarks, Copyrights, and Trade Secrets
- 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)).
- 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)).
- 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 St. Louis Park goes to the District of Minnesota (28 U.S.C. 103), which sits in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji.
Four Kinds of Intellectual Property and What Each Covers
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)).
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.
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)).
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.
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.
Patent infringement damages reach back at most six years before the complaint (35 U.S.C. 286), so a suspected infringement is worth reviewing promptly.
A Minnesota state-law claim brings its own deadline and its own accrual rule. Both come from Minnesota statutes and court decisions and should be reviewed by an attorney at the start of the matter.

Federal and Minnesota Trademark Registration
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)).
A Minnesota business can ask an attorney whether a state-level trademark filing with the Minnesota Secretary of State is worth adding to a federal application. The provisions are in Minn. Stat. chapter 333, and the two registrations are separate.
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)).
The filing date is what starts the patent clock (35 U.S.C. 154(a)(2)), so the timing of an application matters. An attorney can advise whether the invention fits the categories in 35 U.S.C. 101.
Federal and State Courts for Intellectual Property Claims
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.
The federal court for St. Louis Park 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.
State-Law Rules for Trademarks and Trade Secrets
Owners of confidential information in St. Louis Park 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)).
Beyond the federal Lanham Act, a brand owner in St. Louis Park can look to Minnesota’s own trademark registration system. Filings are made with the Minnesota Secretary of State under Minn. Stat. chapter 333, and a state filing does not replace a federal application.
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
Infringement occurs when someone, without authority, makes, uses, offers to sell, or sells any patented invention within the United States, or imports a patented invention into the United States, during the term of the patent (35 U.S.C. 271(a)).
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.
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)).
A person who believes he or she is or is likely to be damaged can bring the civil action under 15 U.S.C. 1125(a)(1).
Copyright Infringement
For writing, images, music, or film, copyright protects the original expression fixed in a tangible medium (17 U.S.C. 102(a)) but never the underlying idea (17 U.S.C. 102(b)).
For a United States work, registration must be made before an infringement suit is instituted (17 U.S.C. 411(a)).
Trade Secret Misappropriation
Trade secret cases often turn on whether the owner took reasonable measures to keep the information secret and whether it has independent economic value from not being generally known, the two elements of 18 U.S.C. 1839(3).
The federal action has a three-year deadline running from discovery, or from when reasonable diligence should have led to discovery (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).
In trademark cases, courts have the power to enjoin violations (15 U.S.C. 1116(a)), and a plaintiff who establishes a violation may recover profits, damages, and costs, subject to sections 1111 and 1114 and the principles of equity (15 U.S.C. 1117(a)).
The copyright statute offers two routes to money relief: actual damages and profits (17 U.S.C. 504(b)) or statutory damages of not less than $750 or more than $30,000 for infringements of any one work (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.
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
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.
For a patent question, bring drawings, notes, prototypes, any patent or application numbers, and information about who has seen or used the invention. For a trademark, bring the name or logo, examples of how it is used, and any registration papers.
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.
