Quick Answers on Patents, Trademarks, Copyrights, and Trade Secrets
- Patent claims are filed in federal court only (28 U.S.C. 1338(a)), and the six-year damages limit in 35 U.S.C. 286 makes early action important.
- Federal trademark registration is available to the owner of a mark used in commerce or to a person with a bona fide intention to use one (15 U.S.C. 1051(a)(1), (b)(1)).
- 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.
- 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)).
- Which court? A case from Hazelwood that belongs in federal court is filed in the Eastern District of Missouri, which holds court in Saint Louis, Hannibal, and Cape Girardeau.
Four Kinds of Intellectual Property and What Each Covers
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)).
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.
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)).
Trade secret protection depends on two things: the owner took reasonable measures to keep the information secret, and the information has independent economic value because it is not generally known or readily ascertainable (18 U.S.C. 1839(3)). Formulas, methods, processes, programs, and codes can all qualify.
Filing Deadlines and Damages Limits
Three years is the copyright limit in 17 U.S.C. 507(b), measured from when the claim accrued. Registration comes first under 17 U.S.C. 411(a), so the clock and the registration process can overlap.
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)).
For patent damages, the look-back is six years from the complaint (35 U.S.C. 286), which is separate from the 20-year patent term measured from the filing date (35 U.S.C. 154(a)(2)).
The federal deadlines above do not decide state-law claims. Missouri 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.

Federal and Missouri Trademark Registration
Federal trademark registration is available both to owners of a mark already used in commerce (15 U.S.C. 1051(a)(1)) and to a person with a bona fide intention, in good faith, to use a mark in commerce (15 U.S.C. 1051(b)(1)), through an application and a verified statement filed with the Patent and Trademark Office.
Missouri also has its own trademark registration. A state filing is made with the Missouri Secretary of State under RSMo 417.005 to 417.066, is separate from the federal register, and does not replace a federal application.
For copyright, protection attaches to original works fixed in a tangible medium (17 U.S.C. 102(a)), but before an infringement suit on a United States work can be instituted, preregistration or registration of the copyright claim must have been made (17 U.S.C. 411(a)). A work created on or after January 1, 1978 lasts for the life of the author plus 70 years (17 U.S.C. 302(a)).
Inventors should keep the 20-year term measured from filing in mind (35 U.S.C. 154(a)(2)), and should confirm early with an attorney that the invention falls within 35 U.S.C. 101.
The Federal Court for St. Louis County
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 Hazelwood is the Eastern District of Missouri. The statute sets the district by county (28 U.S.C. 105), and that court holds court in Saint Louis, Hannibal, and Cape Girardeau.
State-Law Rules for Trademarks and Trade Secrets
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 Hazelwood may also raise a claim under the Missouri Uniform Trade Secrets Act (RSMo 417.450 to 417.467). Which claims fit depends on the facts.
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.
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.
Types of Intellectual Property Claims
Patent Disputes
Patent disputes turn on the patent’s claims and on conduct listed in 35 U.S.C. 271(a), namely making, using, offering to sell, selling, or importing a patented invention without authority.
Because the six-year damages limit in 35 U.S.C. 286 runs back from the complaint, delay can reduce what is recoverable.
Trademark Claims
For a registered mark, the core question is whether the defendant’s use of a reproduction, copy, counterfeit, or colorable imitation is likely to cause confusion, mistake, or deception in connection with goods or services (15 U.S.C. 1114(1)(a)).
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.
Copying of Creative Work
In a copyright case, the first questions are whether the work is protected at all under 17 U.S.C. 102(a) and whether what was copied was protected expression rather than an idea or method excluded by 17 U.S.C. 102(b).
Keeping dated copies of drafts and finished work helps show what was created and when.
Disputes Over Trade Secrets
The Defend Trade Secrets Act lets the owner of a misappropriated trade secret sue when the secret relates to a product or service in interstate or foreign commerce (18 U.S.C. 1836(b)(1)). Whether the information qualifies depends on the definition in 18 U.S.C. 1839(3).
The Missouri Uniform Trade Secrets Act (RSMo 417.450 to 417.467) may provide state-law claims alongside the federal action, with their own deadlines.
What a Court Can Award or Order
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).
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)).
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.
Registering early matters for remedies as well as for suing: statutory damages and attorney’s fees are barred for infringement that began before registration, except when a published work is registered within three months after first publication (17 U.S.C. 412).
Trade secrets: under the federal statute a court may grant an injunction to prevent actual or threatened misappropriation, award damages for actual loss and for unjust enrichment, or impose liability for a reasonable royalty, and if the misappropriation was willful and malicious, award exemplary damages of not more than 2 times the damages awarded, and attorney’s fees in stated circumstances (18 U.S.C. 1836(b)(3)).

Frequently Asked Questions
How far back can I recover damages for patent infringement?
Six years before the complaint. No recovery may be had for infringement committed more than six years before the filing of the complaint (35 U.S.C. 286).
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)).
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.
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.
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)).
Can I bring both federal and Missouri 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 Missouri 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)).
Can I protect a logo or slogan?
A word, name, symbol, or device used to identify and distinguish goods or services and indicate their source can be a trademark or service mark (15 U.S.C. 1127).
