Your Appleton Intellectual Property Attorney
Intellectual property law splits into four main areas, patents, trademarks, copyrights, and trade secrets, and each has its own rules on where a case is filed and how long you have. The sections below explain those rules for a matter arising in Appleton. 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 Calumet, Outagamie, and Winnebago counties, and how Wisconsin law fits alongside federal law. An attorney who handles intellectual property matters can tell you which of these rules apply to your situation.
Intellectual Property Rules at a Glance
- 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).
- 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.
- Copyright covers expression, not ideas: original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), but never an idea, procedure, process, system, or method of operation (17 U.S.C. 102(b)).
- 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.
- Which court? A case from Appleton that belongs in federal court is filed in the Eastern District of Wisconsin, which holds court in Green Bay, Milwaukee, and Oshkosh.
Which Type of Protection Fits Your Situation
Inventions are the domain of patent law. The categories the statute names are processes, machines, manufactures, and compositions of matter (35 U.S.C. 101), and the patent term ends 20 years from the filing date of the application (35 U.S.C. 154(a)(2)).
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.
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.
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)).
Patents: there is no recovery for infringement committed more than six years before the filing of the complaint or counterclaim for infringement (35 U.S.C. 286). Waiting can therefore shrink the damages available even when the patent itself is still in force.
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.

What to Do Before a Dispute Starts
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)).
Federal registration is not the only route. Wisconsin’s trademark registration provisions, Wis. Stat. chapter 132, provide for a state filing with the Wisconsin Department of Financial Institutions that operates separately from the federal register.
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)).
The application date controls the length of patent protection, which ends 20 years after filing (35 U.S.C. 154(a)(2)), so planning the filing is part of protecting the invention.
Federal District Courts and Where They Sit
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 Calumet, Outagamie, and Winnebago counties, the court is the Eastern District of Wisconsin, and it holds court in Green Bay, Milwaukee, and Oshkosh. Because Appleton lies in more than one county, it is worth confirming which county the matter falls in.
What Wisconsin Law Can Add to Federal Protection
Owners of confidential information in Appleton 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)).
A state trademark registration in Wisconsin is a different filing from federal registration (15 U.S.C. 1051). It is made with the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132.
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.
Common Intellectual Property Claims
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.
Both patent owners and people accused of infringing should collect the patent number, product samples, and dates early.
Confusing Similarity and Brand Protection
Infringement of a registered mark means using in commerce a reproduction, counterfeit, copy, or colorable imitation of the mark in connection with the sale, offering for sale, distribution, or advertising of goods or services where the use is likely to cause confusion, mistake, or deception (15 U.S.C. 1114(1)(a)).
State trademark registration in Wisconsin is filed with the Wisconsin Department of Financial Institutions under Wis. Stat. chapter 132, separate from the federal statutes.
Disputes Over Writing, Images, Music, and Film
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)).
Federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)).
Protecting Confidential Business Information
A federal trade secret claim requires a trade secret related to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)), and the information must meet the definition of a trade secret in 18 U.S.C. 1839(3): reasonable secrecy measures and independent economic value.
The Uniform Trade Secrets Act (Wis. Stat. 134.90) may provide state-law claims alongside the federal action, with their own deadlines.
Injunctions and Money Damages by Type of Claim
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.
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.
Under 17 U.S.C. 504, the choice is between actual damages with additional profits and statutory damages, which the court sets between $750 and $30,000 for any one work.
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).
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
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.
Patent matters go faster with drawings, lab notes, patent or application numbers, and a list of who has seen the invention. Trademark matters go faster with the mark itself, samples of its use, and any registration documents.
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 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)).
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 is a trade secret?
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)).
Are trade secret cases filed in federal court?
A federal trade secret action under 18 U.S.C. 1836 is filed in federal district court (18 U.S.C. 1836(c)), and Wisconsin state-law claims are separate claims.
Do federal deadlines apply to Wisconsin state-law claims?
Not automatically. Wisconsin state-law claims have their own limitation periods and accrual rules, set by Wisconsin statutes and court decisions, and an attorney should check them.
When does the trade secret clock start?
From the date the misappropriation is discovered or, by reasonable diligence, should have been discovered (18 U.S.C. 1836(d)).
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.
