Intellectual Property Rules at a Glance
- Who can be liable for patent infringement? Anyone who, without authority, makes, uses, offers to sell, or sells a patented invention in the United States, or imports it (35 U.S.C. 271(a)).
- 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)).
- Three years to bring a copyright claim (17 U.S.C. 507(b)), and federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(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)).
- Where is my case filed? Sulphur is in the Western District of Louisiana, and that court holds court in Alexandria, Lafayette, Lake Charles, Monroe, Opelousas, and Shreveport (28 U.S.C. 98).
Four Kinds of Intellectual Property and What Each Covers
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)).
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)).
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
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)).
A patent owner who waits loses damages: under 35 U.S.C. 286, no recovery may be had for infringement committed more than six years before the complaint. The patent itself lasts 20 years from filing (35 U.S.C. 154(a)(2)).
The federal deadlines above do not decide state-law claims. Louisiana 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.

Registration Steps for Trademarks and Copyrights
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. Louisiana’s trademark registration provisions, La. R.S. 51:211 and following sections, provide for a state filing with the Louisiana Secretary of State that operates separately from the federal register.
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)).
The filing date is what starts the patent clock (35 U.S.C. 154(a)(2)), so the timing of an application matters. An attorney can advise whether the invention fits the categories in 35 U.S.C. 101.
Federal District Courts and Where They Sit
Patent, plant variety protection, and copyright claims belong exclusively in federal court: the district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents, plant variety protection, copyrights, and trademarks, and no state court may hear the patent, plant variety protection, and copyright claims (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court.
The federal court for Sulphur is the Western District of Louisiana. The statute sets the district by county (28 U.S.C. 98), and that court holds court in Alexandria, Lafayette, Lake Charles, Monroe, Opelousas, and Shreveport.
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 Uniform Trade Secrets Act (La. R.S. 51:1431 to 51:1439). The state and federal claims are separate.
A state trademark registration in Louisiana is a different filing from federal registration (15 U.S.C. 1051). It is made with the Louisiana Secretary of State under La. R.S. 51:211 and following sections.
A lawyer can compare the federal and state routes for your situation and explain the tradeoffs.
Common Intellectual Property Claims
Patent Claims and Defenses
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.
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.
Trademark Infringement and Brand Disputes
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)).
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
Copying of Creative Work
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 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.
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
What a Successful Claim Can Recover
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)).
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)).
The registration date can decide whether statutory damages and attorney’s fees are available at all. Section 412 of the copyright statute bars them for infringement commenced before registration, subject to a three-month window after first publication.
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)).

What an Attorney Will Want to See
Bring a simple chronology. When was the work created, when was it first shared or sold, and when did you first notice the copying or use? Many of the deadlines on this page run from those events.
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
Can a patent case be brought in Louisiana state court?
No. Patent claims are within the exclusive jurisdiction of the federal district courts (28 U.S.C. 1338(a)), so a case from Sulphur is filed in the Western District of Louisiana.
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 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)).
Which federal court covers Sulphur?
The Western District of Louisiana (28 U.S.C. 98).
Can a trademark claim be brought under Louisiana law?
Possibly. Louisiana 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 software or written material?
Written material and other original expression fixed in a tangible medium can be protected by copyright (17 U.S.C. 102(a)), but not the underlying ideas, procedures, or methods of operation (17 U.S.C. 102(b)).
