Your Libertyville 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 Libertyville. You will find the quick answers first, then the definitions, deadlines, registration, the courts, state law, and the basic elements of infringement claims, with the statute behind each point. Deadlines in intellectual property cases run on fixed dates, so learning them early usually helps more than trying to catch up later.

The Short Answers: Deadlines, Courts, and Protection

  • Patent term and damages: a patent lasts 20 years from the filing date of the application (35 U.S.C. 154(a)(2)), and no recovery can be had for infringement more than six years before the complaint (35 U.S.C. 286).
  • Trademarks can be registered federally and in Illinois. The federal register is set up by 15 U.S.C. 1051, and state registration is filed with the Illinois Secretary of State under the Trademark Registration and Protection Act, 765 ILCS 1036.
  • 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)).
  • The trade secret clock runs from discovery: three years from when the misappropriation was, or with reasonable diligence should have been, discovered (18 U.S.C. 1836(d)).
  • Which court? A case from Libertyville that belongs in federal court is filed in the Northern District of Illinois, which holds court in Chicago, Wheaton, Freeport, and Rockford.

The Four Main Areas of Intellectual Property Law

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)).

If the issue is a business name, logo, or slogan, the question is trademark, which the Lanham Act defines as a word, name, symbol, or device that identifies and distinguishes goods and indicates their source (15 U.S.C. 1127), with service marks covering 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)).

Unlike a patent, a trade secret is kept private. The federal definition requires reasonable secrecy measures and independent economic value from not being generally known or readily ascertainable through proper means (18 U.S.C. 1839(3)).

Time Limits That Matter in Patent, Copyright, and Trade Secret Cases

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)).

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.

Steps That Strengthen a Claim Before It Is Needed

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.

A Illinois business can ask an attorney whether a state-level trademark filing with the Illinois Secretary of State is worth adding to a federal application. The provisions are in the Trademark Registration and Protection Act, 765 ILCS 1036, and the two registrations are separate.

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 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.

Where an Intellectual Property Case From Libertyville Is Filed

In practice, patent and copyright disputes are filed in federal district court (28 U.S.C. 1338(a)), federal trade secret claims start there as well (18 U.S.C. 1836(c)), and a trademark dispute can be filed in federal or state court.

The federal court for Libertyville is the Northern District of Illinois. The statute sets the district by county (28 U.S.C. 93), and that court holds court in Chicago, Wheaton, Freeport, and Rockford.

State-Law Rules for Trademarks and Trade Secrets

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 Libertyville 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)).

Beyond the federal Lanham Act, a brand owner in Libertyville can look to Illinois’s own trademark registration system. Filings are made with the Illinois Secretary of State under the Trademark Registration and Protection Act, 765 ILCS 1036, and a state filing does not replace a federal application.

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

Patent Claims and Defenses

A patent claim asks whether the accused product or process is covered by the patent and whether the accused party acted without authority. The forms of infringement listed in 35 U.S.C. 271(a) are making, using, offering to sell, selling, and importing.

The patent term is 20 years from the filing date (35 U.S.C. 154(a)(2)), so a case about an expired patent is limited to past infringement.

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 Illinois is filed with the Illinois Secretary of State under the Trademark Registration and Protection Act, 765 ILCS 1036, separate from the federal statutes.

Protecting Creative Work

Creative disputes involve two threshold points: the work must be an original work of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and the claim cannot rest on an idea or system (17 U.S.C. 102(b)).

For a United States work, registration must be made before an infringement suit is instituted (17 U.S.C. 411(a)).

Trade Secret Claims

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.

Documents showing who had access, and what confidentiality steps existed, are among the first things to preserve.

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)).

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)).

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).

For a misappropriated trade secret, 18 U.S.C. 1836(b)(3) authorizes an injunction against actual or threatened misappropriation, damages for actual loss and unjust enrichment or a reasonable royalty, exemplary damages up to 2 times for willful and malicious misappropriation, and reasonable attorney’s fees to the prevailing party in stated situations.

Preparing for a First Conversation

Write down a short timeline before the call: when the work or invention was made, when it was first shown to anyone, and when you learned of the problem. The federal deadlines above are measured from dates like these.

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.

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.

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)).

Illinois has three federal judicial districts: the Northern, Central, and Southern Districts of Illinois (28 U.S.C. 93).

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?
