Your Mehlville Intellectual Property Attorney
A patent, a trademark, a copyright, and a trade secret are four different things with four different sets of rules. For a Mehlville business, artist, or inventor, the first step is knowing which one is actually involved, and this page walks through how to tell. 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.
Your Key Federal and Missouri Rules in One Place
- 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 Missouri. The federal register is set up by 15 U.S.C. 1051, and state registration is filed with the Missouri Secretary of State under RSMo 417.005 to 417.066.
- How long does a copyright last? For works created on or after January 1, 1978, the life of the author plus 70 years (17 U.S.C. 302(a)), with different counts for joint works and works made for hire.
- 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)).
- Federal district: for St. Louis County, the Eastern District of Missouri under 28 U.S.C. 105, holding court in Saint Louis, Hannibal, and Cape Girardeau.
The Four Main Areas of Intellectual Property Law
A patent protects an invention. Whoever invents or discovers a new and useful process, machine, manufacture, or composition of matter may obtain a patent, subject to the conditions and requirements of the patent statute (35 U.S.C. 101). The term is 20 years from the date the application was filed (35 U.S.C. 154(a)(2)).
A brand is protected as a trademark when it functions to identify and distinguish goods from those of others and to indicate the source of the goods (15 U.S.C. 1127). The same statute defines a service mark for the source of services.
Copyright protects expression, not ideas. The subject matter is original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and protection does not extend to any idea, procedure, process, system, or method of operation, however it is described (17 U.S.C. 102(b)).
A trade secret is 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)). The statute covers financial, business, scientific, and technical information such as patterns, plans, formulas, designs, methods, processes, programs, and codes.
Time Limits That Matter in Patent, Copyright, and Trade Secret Cases
Copyright: a civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)). Because a United States work must also be registered before an infringement suit can be filed (17 U.S.C. 411(a)), the registration step should not be left until after the dispute begins.
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.
Claims under Missouri 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.

What to Do Before a Dispute Starts
A business planning a brand can file for federal registration based on actual use in commerce (15 U.S.C. 1051(a)(1)) or based on a bona fide intention to use it (15 U.S.C. 1051(b)(1)).
State registration is a different filing from a federal application. In Missouri it is made with the Missouri Secretary of State under RSMo 417.005 to 417.066, and an attorney can tell you whether a state filing, a federal filing, or both suit your plans.
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)).
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 District Courts and Where They Sit
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.
By statute the state has two federal districts, known as the Eastern and Western Districts of Missouri (28 U.S.C. 105). A federal case from Mehlville is filed in the Eastern District of Missouri, where court is held at Saint Louis, Hannibal, and Cape Girardeau.
State-Law Rules for Trademarks and Trade Secrets
A misappropriated trade secret can support a federal claim under 18 U.S.C. 1836(b) when it is connected to interstate or foreign commerce, and it may also support a claim under the Missouri Uniform Trade Secrets Act (RSMo 417.450 to 417.467). The state and federal claims are separate.
A state trademark registration in Missouri is a different filing from federal registration (15 U.S.C. 1051). It is made with the Missouri Secretary of State under RSMo 417.005 to 417.066.
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
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.
Because the six-year damages limit in 35 U.S.C. 286 runs back from the complaint, delay can reduce what is recoverable.
Disputes Over Names, Logos, and Brands
Brand disputes often involve both a registered mark and one that has never been registered. Registered marks are protected against likely confusion under 15 U.S.C. 1114(1)(a), and 15 U.S.C. 1125(a)(1) covers false designation of origin more broadly.
State trademark registration in Missouri is filed with the Missouri Secretary of State under RSMo 417.005 to 417.066, 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.
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)).
Injunctions and Money Damages by Type of Claim
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).
A brand owner who establishes a violation may recover the defendant’s profits, damages sustained, and costs (15 U.S.C. 1117(a)), and can ask the court for an injunction to stop the violation (15 U.S.C. 1116(a)), both subject to the principles of equity.
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)).

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.
Inventors should collect drawings, notes, and application numbers, and brand owners should collect the mark, examples of use, and any registration papers, before the first conversation.
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
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 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)).
Do I have to register a copyright before I sue?
For a United States work, yes. No civil action for infringement of the copyright may be instituted until preregistration or registration of the copyright claim has been made (17 U.S.C. 411(a)), with a provision for cases where registration was refused.
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)).
How many federal districts does Missouri have?
Missouri has two federal judicial districts: the Eastern and Western Districts of Missouri (28 U.S.C. 105).
Can a trademark claim be brought under Missouri law?
Possibly. Missouri law may provide trademark claims of its own alongside the federal ones, and which apply depends on the mark and the facts. An attorney can explain the options.
Do deadlines differ for different kinds of intellectual property?
Yes. Copyright and federal trade secret claims each have a three-year period, measured differently (17 U.S.C. 507(b); 18 U.S.C. 1836(d)), and patent damages are limited to six years before the complaint (35 U.S.C. 286).
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)).
