Your Hudson Intellectual Property Attorney
If you are trying to protect an invention, a brand, or a creative work in Hudson, or you have been accused of infringing someone else’s, you probably want plain answers about deadlines, courts, and what each kind of protection covers. Federal statutes set most of them, so many answers can be checked. Keep reading for the deadlines, the registration steps for trademarks and copyrights, the court structure for St. Croix County, the trade secret rules, and the elements behind the most common infringement claims, citing the statute each time. These rules apply across Wisconsin, and an attorney familiar with the Western District of Wisconsin can explain what to expect there.
The Short Answers: Deadlines, Courts, and Protection
- Patent claims are filed in federal court only (28 U.S.C. 1338(a)), and the six-year damages limit in 35 U.S.C. 286 makes early action important.
- Infringing a registered mark means using a reproduction, counterfeit, copy, or colorable imitation in a way likely to cause confusion (15 U.S.C. 1114(1)(a)).
- 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)).
- 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 Hudson goes to the Western District of Wisconsin (28 U.S.C. 130), which sits in Eau Claire, La Crosse, Madison, Superior, and Wausau.
The Four Main Areas of Intellectual Property Law
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)).
A trade secret is information the owner has taken reasonable measures to keep secret and that derives independent economic value from not being generally known to, and not being readily ascertainable through proper means by, another person (18 U.S.C. 1839(3)). The statute covers financial, business, scientific, and technical information such as patterns, plans, formulas, designs, methods, processes, programs, and codes.
Why Timing Matters in Intellectual Property Disputes
The copyright deadline is three years after the claim accrued (17 U.S.C. 507(b)). An owner who has not registered should treat registration as part of the first steps, since no infringement action on a United States work can be instituted before it (17 U.S.C. 411(a)).
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)).
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.
The federal deadlines above do not decide state-law claims. Wisconsin sets its own limitation periods and accrual rules, and an attorney can tell you which apply to a trade secret or unfair competition claim brought under state law.

Steps That Strengthen a Claim Before It Is Needed
Federal trademark registration is available both to owners of a mark already used in commerce (15 U.S.C. 1051(a)(1)) and to a person with a bona fide intention, in good faith, to use a mark in commerce (15 U.S.C. 1051(b)(1)), through an application and a verified statement filed with the Patent and Trademark Office.
State registration is a different filing from a federal application. In Wisconsin it is made with the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132, 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)).
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
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.
Wisconsin is divided into two federal judicial districts (28 U.S.C. 130). St. Croix County is in the Western District of Wisconsin, which holds court in Eau Claire, La Crosse, Madison, Superior, and Wausau.
How Wisconsin Law Fits In
Owners of confidential information in Hudson can look to two sources: the Uniform Trade Secrets Act (Wis. Stat. 134.90) 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 Wisconsin’s registration system, which runs through the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132. The two operate separately.
A lawyer can compare the federal and state routes for your situation and explain the tradeoffs.
The Basics of Each Type of Claim
Patent Claims and Defenses
The basic patent infringement rule is in 35 U.S.C. 271(a): without authority, making, using, offering to sell, or selling a patented invention in the United States, or importing one, during the patent term.
A patent case is filed in federal district court (28 U.S.C. 1338(a)).
Trademark Infringement and Brand Disputes
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.
State trademark registration in Wisconsin is filed with the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132, separate from the federal statutes.
Copying of 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)).
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
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.
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)).
Damages, Injunctions, and Other Relief
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).
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)).
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)).

What an Attorney Will Want to See
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.
If the issue is a patent, gather technical drawings, descriptions, and any application numbers. If it is a trademark, gather the mark, examples of use, and registration information.
For a copyright question, bring the work, dated drafts, any registration papers, and examples of the copying. For a trade secret question, bring a description of the information, who had access, and what confidentiality steps were in place, such as agreements and access controls.

Frequently Asked Questions
How long does a patent last?
A patent lasts 20 years from the date the application was filed in the United States (35 U.S.C. 154(a)(2)), so the filing date, not the issue date, sets the end of the term.
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 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.
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)).
How many federal districts does Wisconsin have?
Wisconsin has two federal judicial districts: the Eastern and Western Districts of Wisconsin (28 U.S.C. 130).
Does state registration replace federal registration?
No. A state registration, where one is available, is a separate filing from federal registration on the principal register (15 U.S.C. 1051), and each operates on its own.
How long do I have to bring a copyright claim?
Three years after the claim accrued (17 U.S.C. 507(b)), and registration must come before suit on a United States work (17 U.S.C. 411(a)).
How do I keep information as a trade secret?
Take reasonable measures to keep it secret, because that is one of the two elements of the definition (18 U.S.C. 1839(3)), and consult an attorney about what measures are reasonable for your business.
