Your Sturgeon Bay 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 Wisconsin rules that most often decide how an intellectual property matter from Sturgeon Bay unfolds. This page covers the deadlines, the definitions that decide whether something is protected, the federal district court for Door County, and the Wisconsin rules that sit next to the federal ones. The facts of your situation decide which area of law controls, and an attorney who practices in federal court can sort that out quickly.
Deadlines and Courts: The Short Version
- 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 Wisconsin’s own registration is a separate filing with the Wisconsin Department of Financial Institutions.
- 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)).
- Wisconsin has its own trade secret statute, the Uniform Trade Secrets Act (Wis. Stat. 134.90), and the federal action in 18 U.S.C. 1836 sits alongside it.
- A federal case from Sturgeon Bay goes to the Eastern District of Wisconsin (28 U.S.C. 130), which sits in Green Bay, Milwaukee, and Oshkosh.
Which Type of Protection Fits Your Situation
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)).
Under 15 U.S.C. 1127, a trademark is any word, name, symbol, or device, or a combination, that identifies and distinguishes one person’s goods from another’s and indicates their source, and a service mark performs that function 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.
Filing Deadlines and Damages Limits
For copyright infringement, the statute sets three years from when the claim accrued (17 U.S.C. 507(b)), and registration or a refusal of registration must come before suit on a United States work (17 U.S.C. 411(a)).
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)).
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.
Claims under Wisconsin 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
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)).
Wisconsin also has its own trademark registration. A state filing is made with the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132, is separate from the federal register, and does not replace a federal application.
A copyright owner cannot file an infringement action on a United States work before registration has been made (17 U.S.C. 411(a)), although a refusal of registration can also open the door to suit if the Register of Copyrights is notified and served with the complaint.
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.
The Federal Court for Door County
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.
Wisconsin is divided into two federal judicial districts (28 U.S.C. 130). Door County is in the Eastern District of Wisconsin, which holds court in Green Bay, Milwaukee, and Oshkosh.
Trade Secrets and Trademarks Under Wisconsin Law
Owners of confidential information in Sturgeon Bay 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.
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 Disputes
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.
A patent case is filed in federal district court (28 U.S.C. 1338(a)).
Disputes Over Names, Logos, and Brands
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.
State trademark registration in Wisconsin is filed with the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132, separate from the federal statutes.
Copyright Claims
In a copyright case, the first questions are whether the work is protected at all under 17 U.S.C. 102(a) and whether what was copied was protected expression rather than an idea or method excluded by 17 U.S.C. 102(b).
Federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)).
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)).
A continuing misappropriation is treated as a single claim for the federal deadline (18 U.S.C. 1836(d)).
What a Successful Claim Can Recover
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).
The trademark remedies are set out in 15 U.S.C. 1116(a), which gives courts the power to grant injunctions, and 15 U.S.C. 1117(a), which lets a plaintiff recover defendant’s profits, damages, and costs once a violation is established.
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)).
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)).

What to Gather Before You Talk to an Attorney
Before you talk to anyone, list the key dates in order. Copyright and federal trade secret deadlines run from accrual and discovery, and patent damages look back from the complaint, so a clean timeline shows where you stand.
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.
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
Can a patent case be brought in Wisconsin state court?
No. Patent claims are within the exclusive jurisdiction of the federal district courts (28 U.S.C. 1338(a)), so a case from Sturgeon Bay is filed in the Eastern District of Wisconsin.
What is trademark infringement?
For a registered mark, it is using in commerce a reproduction, counterfeit, copy, or colorable imitation in connection with goods or services where the use is likely to cause confusion, mistake, or deception (15 U.S.C. 1114(1)(a)).
What kinds of work does copyright cover?
Original works of authorship fixed in any tangible medium of expression (17 U.S.C. 102(a)), including literary, musical, dramatic, and pictorial works, motion pictures, sound recordings, and architectural works.
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.
Where does the federal court for Sturgeon Bay hold court?
The Eastern District of Wisconsin holds court in Green Bay, Milwaukee, and Oshkosh (28 U.S.C. 130).
Can I bring both federal and Wisconsin 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 Wisconsin law. An attorney can advise which to bring.
Why does timing matter in an intellectual property dispute?
Because federal statutes set fixed limits, such as three years for copyright (17 U.S.C. 507(b)) and for federal trade secret claims (18 U.S.C. 1836(d)), and six years of look-back for patent damages (35 U.S.C. 286), waiting can cost rights and money.
Can I protect a business idea?
An idea by itself is not protected by copyright (17 U.S.C. 102(b)). An invention that fits a category in 35 U.S.C. 101 may be patentable, and confidential business information may qualify as a trade secret (18 U.S.C. 1839(3)).
