Your Eden Prairie 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 Eden Prairie unfolds. Below you will find the key deadlines at a glance, what each type of protection covers, the steps that come before a lawsuit, which federal court hears a case from Hennepin County, and how Minnesota law fits alongside federal law. These rules apply across Minnesota, and an attorney familiar with the District of Minnesota can explain what to expect there.
The Short Answers: Deadlines, Courts, and Protection
- Patents belong in federal court. Federal district courts have original jurisdiction over patent claims (28 U.S.C. 1338(a)), and damages cannot reach back more than six years before the complaint (35 U.S.C. 286).
- Trademark claims can go to federal or state court (28 U.S.C. 1338(a)), and Minnesota’s own registration is a separate filing with the Minnesota Secretary of State.
- 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.
- 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.
- Federal district: for Hennepin County, the District of Minnesota under 28 U.S.C. 103, holding court in Winona, Mankato, Saint Paul, Minneapolis, Duluth, Fergus Falls, and Bemidji.
Which Type of Protection Fits Your Situation
Patents cover new and useful processes, machines, manufactures, and compositions of matter (35 U.S.C. 101). Protection lasts until 20 years after the date on which the application was filed in the United States (35 U.S.C. 154(a)(2)), so the filing date matters more than the date the patent issues.
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)).
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.
Deadlines for Intellectual Property Claims
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.
A patent owner who waits loses damages: under 35 U.S.C. 286, no recovery may be had for infringement committed more than six years before the complaint. The patent itself lasts 20 years from filing (35 U.S.C. 154(a)(2)).
State-law claims, such as a claim under the Uniform Trade Secrets Act (Minn. Stat. chapter 325C) or a state trademark claim, have their own rules on limitation periods and on when a claim begins to run. Those are set by Minnesota statutes and court decisions, so the dates should be checked by an attorney rather than assumed from the federal deadlines.

Registering and Protecting Your Rights
A business planning a brand can file for federal registration based on actual use in commerce (15 U.S.C. 1051(a)(1)) or based on a bona fide intention to use it (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.
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)).
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.
Federal and State Courts for Intellectual Property Claims
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.
The federal court for Eden Prairie 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.
Trade Secrets and Trademarks Under Minnesota Law
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 Eden Prairie may also raise a claim under the Uniform Trade Secrets Act (Minn. Stat. chapter 325C). Which claims fit depends on the facts.
A brand owner in Eden Prairie may have state-law options in addition to federal ones. Minnesota’s trademark registration provisions are found in Minn. Stat. chapter 333, and the filing office is the Minnesota Secretary of State.
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.
The Basics of Each Type of Claim
Patent Infringement
Patent disputes turn on the patent’s claims and on conduct listed in 35 U.S.C. 271(a), namely making, using, offering to sell, selling, or importing a patented invention without authority.
Because the six-year damages limit in 35 U.S.C. 286 runs back from the complaint, delay can reduce what is recoverable.
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.
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
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
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.
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
Damages, Injunctions, and Other Relief
For patents, 35 U.S.C. 284 sets the damages floor at a reasonable royalty and lets the court increase damages up to three times the amount found or assessed, and 35 U.S.C. 283 allows injunctions according to the principles of equity, on terms the court considers reasonable.
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)).
Registering early matters for remedies as well as for suing: statutory damages and attorney’s fees are barred for infringement that began before registration, except when a published work is registered within three months after first publication (17 U.S.C. 412).
For a misappropriated trade secret, 18 U.S.C. 1836(b)(3) authorizes an injunction against actual or threatened misappropriation, damages for actual loss and unjust enrichment or a reasonable royalty, exemplary damages up to 2 times for willful and malicious misappropriation, and reasonable attorney’s fees to the prevailing party in stated situations.

Getting Your Records in Order
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.
Useful patent records include sketches, notebooks, prototypes, and application numbers. Useful trademark records include the logo or name, packaging or signage showing use, and state or federal registration papers.
For copyright, gather the work, drafts with dates, and examples of copying. For a trade secret, gather what the information is, who could see it, and what confidentiality agreements or security measures applied.

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).
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 Minnesota 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.
How long do I have to bring a trade secret claim under federal law?
Three years after the misappropriation is discovered or, by the exercise of reasonable diligence, should have been discovered, and a continuing misappropriation counts as a single claim (18 U.S.C. 1836(d)).
Which court handles patent and copyright cases from Eden Prairie?
Both belong exclusively in federal district court (28 U.S.C. 1338(a)), which for Eden Prairie means the District of Minnesota.
Can I bring both federal and Minnesota claims?
Often yes. A dispute can involve federal claims, such as under 15 U.S.C. 1114 or 18 U.S.C. 1836, and state-law claims under Minnesota law. An attorney can advise which to bring.
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 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)).
