Your Downers Grove 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 Illinois rules that most often decide how an intellectual property matter from Downers Grove unfolds. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for DuPage County, Illinois’s own trademark and trade secret rules, and what an infringement claim involves. Talking with an attorney who works in the Northern District of Illinois can turn these general rules into a plan for your matter.
Deadlines and Courts: The Short Version
- A patent case is a federal case. The district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents (28 U.S.C. 1338(a)), and infringement damages are limited to the six years before the complaint (35 U.S.C. 286).
- 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)).
- 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)).
- Trade secrets get a federal civil action when the secret relates to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)), filed in federal district court (18 U.S.C. 1836(c)).
- A federal case from Downers Grove goes to the Northern District of Illinois (28 U.S.C. 93), which sits in Chicago, Wheaton, Freeport, and Rockford.
Patents, Trademarks, Copyrights, and Trade Secrets Compared
If you have made something new and useful, such as a device, a process, a manufactured article, or a composition, a patent is the tool the statute provides (35 U.S.C. 101). The grant runs from issuance to 20 years after the application was filed (35 U.S.C. 154(a)(2)).
A trademark identifies and distinguishes goods and their source. The statute defines it as any word, name, symbol, or device, or any combination, used by a person, or which a person has a bona fide intention to use in commerce and applies to register, to identify and distinguish that person’s goods from those manufactured or sold by others and to indicate the source (15 U.S.C. 1127). A service mark does the same for services.
Copyright protects original works of authorship fixed in any tangible medium of expression (17 U.S.C. 102(a)), such as literary, musical, dramatic, and pictorial works, motion pictures, sound recordings, and architectural works. It never extends to an idea, procedure, process, system, method of operation, concept, principle, or discovery (17 U.S.C. 102(b)).
Business and technical information such as plans, formulas, and processes qualifies as a trade secret only if the owner has taken reasonable measures to keep it secret and it derives independent economic value from secrecy (18 U.S.C. 1839(3)).
Deadlines for Intellectual Property Claims
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)).
Trade secret claims under federal law must be filed within three years of discovery, or of when reasonable diligence would have revealed the misappropriation, and continuing misappropriation is one 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.
Claims under Illinois 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.

Registering and Protecting Your Rights
The Lanham Act sets two routes to the principal register: use in commerce (15 U.S.C. 1051(a)(1)) and a bona fide intention to use (15 U.S.C. 1051(b)(1)). Each requires an application, a verified statement, and the prescribed fee.
Federal registration is not the only route. Illinois’s trademark registration provisions, the Trademark Registration and Protection Act, 765 ILCS 1036, provide for a state filing with the Illinois Secretary of State that operates separately from the federal register.
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.
A patent application starts the 20-year term (35 U.S.C. 154(a)(2)), and the invention must fit a statutory category such as a process, machine, manufacture, or composition of matter (35 U.S.C. 101). An attorney can review both points before you file.
Federal and State Courts for Intellectual Property Claims
Federal law fixes the forum for most intellectual property claims: exclusive federal jurisdiction over patents and copyrights (28 U.S.C. 1338(a)), original federal jurisdiction over Defend Trade Secrets Act claims (18 U.S.C. 1836(c)), and concurrent state jurisdiction over trademarks.
Illinois is divided into three federal judicial districts (28 U.S.C. 93). DuPage County is in the Northern District of Illinois, which holds court in Chicago, Wheaton, Freeport, and Rockford.
What Illinois Law Can Add to Federal Protection
Illinois has a trade secret statute of its own, the Illinois Trade Secrets Act (765 ILCS 1065/1 and following sections). A trade secret dispute from Downers Grove can involve that statute, and the federal Defend Trade Secrets Act adds a civil action in federal court for a trade secret related to a product or service used in interstate or foreign commerce (18 U.S.C. 1836(b)(1), (c)).
A state trademark registration in Illinois is a different filing from federal registration (15 U.S.C. 1051). It is made with the Illinois Secretary of State under the Trademark Registration and Protection Act, 765 ILCS 1036.
Choosing between state and federal claims, or bringing both, is something an attorney should decide after reviewing what happened and what proof exists.
The Claims Behind Most Intellectual Property Disputes
Using an Invention Without Permission
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
Two federal provisions do most of the work in trademark cases: 15 U.S.C. 1114(1)(a) for registered marks and 15 U.S.C. 1125(a)(1) for misleading uses of any word, term, name, symbol, or device, registered or not.
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
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)).
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
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)).
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)).
What a Successful Claim Can Recover
In a patent case, the statute directs an award of damages adequate to compensate for the infringement and never less than a reasonable royalty, plus interest and costs, with increases of up to three times possible in the court’s discretion (35 U.S.C. 284). Injunctions are available in accordance with 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 damages can be measured by the owner’s actual damages and the infringer’s attributable profits (17 U.S.C. 504(b)), or by statutory damages between $750 and $30,000 per work as the court considers just (17 U.S.C. 504(c)(1)).
Under 17 U.S.C. 412, an owner who registers after an infringement has started may lose access to statutory damages and attorney’s fees for that infringement, unless the work was published and registered within three months of first publication.
The Defend Trade Secrets Act lists the remedies: an injunction, damages for actual loss and unjust enrichment (or a reasonable royalty), exemplary damages of not more than 2 times the damages for willful and malicious misappropriation, and attorney’s fees in the situations the statute names (18 U.S.C. 1836(b)(3)).

Documents and Dates That Help
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.
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 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
What counts as patent infringement?
Without authority, making, using, offering to sell, or selling a patented invention in the United States, or importing one into the United States, during the term of the patent (35 U.S.C. 271(a)).
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)).
Which court hears a copyright case from Downers Grove?
The federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)). For Downers Grove, that is the Northern District of Illinois.
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.
How many federal districts does Illinois have?
Illinois has three federal judicial districts: the Northern, Central, and Southern Districts of Illinois (28 U.S.C. 93).
Can I bring both federal and Illinois 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 Illinois law. An attorney can advise which to bring.
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)).
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.
