Your Green 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 Green Bay 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 Brown County, and how Wisconsin law fits alongside federal law. These rules apply across Wisconsin, and an attorney familiar with the Eastern District of Wisconsin can explain what to expect there.
Your Key Federal and Wisconsin Rules in One Place
- 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 Wisconsin. The federal register is set up by 15 U.S.C. 1051, and state registration is filed with the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132.
- Register first, sue second. No civil action for infringement of the copyright in a United States work can be instituted until registration has been made or refused in the way the statute provides (17 U.S.C. 411(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)).
- The federal court for Green Bay is the Eastern District of Wisconsin, with court held at Green Bay, Milwaukee, and Oshkosh (28 U.S.C. 130).
Four Kinds of Intellectual Property and What Each Covers
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.
Names, logos, and slogans that tell customers who is behind a product are trademarks, defined in 15 U.S.C. 1127 as any word, name, symbol, or device used to identify and distinguish a person’s goods and to indicate their source. A service mark does the same job 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)).
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.
Filing Deadlines and Damages Limits
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.
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.
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
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.
Under 28 U.S.C. 130, Wisconsin’s counties are grouped into two federal districts. For Brown County, the court is the Eastern District of Wisconsin, and it holds court in Green Bay, Milwaukee, and Oshkosh.
Wisconsin Law Alongside Federal 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 Green Bay may also raise a claim under the Uniform Trade Secrets Act (Wis. Stat. 134.90). Which claims fit depends on the facts.
A brand owner in Green Bay may have state-law options in addition to federal ones. Wisconsin’s trademark registration provisions are found in Wis. Stat. chapter 132, and the filing office is the Wisconsin Department of Financial Institutions.
Which claims to bring, and in which court, is a strategy question for an attorney who can read the documents.
The Basics of Each Type of Claim
Claims That a Patent Is Being Infringed
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 and Unfair Competition 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.
A state registration in Wisconsin (Wis. Stat. chapter 132) is different from federal registration on the principal register (15 U.S.C. 1051).
Copyright Claims
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)).
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)).
Trade Secret Misappropriation
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)).
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
Remedies in Intellectual Property Cases
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)).
Delay in registering can cost more than time. Infringement that starts before the effective date of registration generally cannot support statutory damages or attorney’s fees, with the exception in 17 U.S.C. 412 for registration within three months after 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
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.
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.
Bring the original work and dated drafts for a copyright issue, and a description of the information, access records, and confidentiality measures for a trade secret issue.

Frequently Asked Questions
Where is a patent infringement case filed?
In federal district court. The district courts have original jurisdiction of civil actions arising under patent law, and that jurisdiction is exclusive (28 U.S.C. 1338(a)). For Green Bay, that is the Eastern District of Wisconsin.
Can I register my business name or logo as a trademark?
A word, name, symbol, or device used to identify and distinguish goods and indicate their source is a trademark (15 U.S.C. 1127), and the owner of a mark used in commerce may request federal registration (15 U.S.C. 1051(a)(1)).
Can I copyright an idea?
No. Copyright never extends to any idea, procedure, process, system, method of operation, concept, principle, or discovery (17 U.S.C. 102(b)). It protects the original expression of an idea.
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)).
Do I have to file in federal court?
For patents and copyrights, yes: the federal jurisdiction is exclusive (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court, and a federal trade secret action is filed in federal district court (18 U.S.C. 1836(c)).
Does Wisconsin law protect trade secrets?
Yes. Wisconsin has the Uniform Trade Secrets Act (Wis. Stat. 134.90), and the federal Defend Trade Secrets Act (18 U.S.C. 1836) adds a separate federal action.
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.
What should I do if someone copies my work?
Note the dates, keep copies, and speak with an attorney early, since deadlines such as three years for copyright (17 U.S.C. 507(b)) and six years of look-back for patent damages (35 U.S.C. 286) run from the events.
