Your Eunice 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 Eunice. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for Acadia and St. Landry parishes, Louisiana’s own trademark and trade secret rules, and what an infringement claim involves. An attorney who handles intellectual property matters can tell you which of these rules apply to your situation.
Intellectual Property Rules at a Glance
- 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).
- Trademarks can be registered federally and in Louisiana. The federal register is set up by 15 U.S.C. 1051, and state registration is filed with the Louisiana Secretary of State under La. R.S. 51:211 and following sections.
- Copyright covers expression, not ideas: original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), but never an idea, procedure, process, system, or method of operation (17 U.S.C. 102(b)).
- Louisiana has its own trade secret statute, the Uniform Trade Secrets Act (La. R.S. 51:1431 to 51:1439), and the federal action in 18 U.S.C. 1836 sits alongside it.
- A federal case from Eunice goes to the Western District of Louisiana (28 U.S.C. 98), which sits in Alexandria, Lafayette, Lake Charles, Monroe, Opelousas, and Shreveport.
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)).
Names, logos, and slogans that tell customers who is behind a product are trademarks, defined in 15 U.S.C. 1127 as any word, name, symbol, or device used to identify and distinguish a person’s goods and to indicate their source. A service mark does the same job 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.
How Long Do You Have to Bring a Claim?
Under 17 U.S.C. 507(b), a civil copyright action must be commenced within three years after the claim accrued, and under 17 U.S.C. 411(a) the copyright claim for a United States work must be registered, or registration refused, before that action is instituted.
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)).
A Louisiana state-law claim brings its own deadline and its own accrual rule. Both come from Louisiana statutes and court decisions and should be reviewed by an attorney at the start of the matter.

What to Do Before a Dispute Starts
For a trademark, the owner of a mark used in commerce may request registration on the principal register by paying the prescribed fee and filing an application and a verified statement with the Patent and Trademark Office (15 U.S.C. 1051(a)(1)). A person with a bona fide intention to use a mark in commerce may also apply (15 U.S.C. 1051(b)(1)).
State registration is a different filing from a federal application. In Louisiana it is made with the Louisiana Secretary of State under La. R.S. 51:211 and following sections, and an attorney can tell you whether a state filing, a federal filing, or both suit your plans.
Registering a copyright before there is a dispute avoids a delay later. The statute says no civil action for infringement of the copyright in a United States work may be instituted until preregistration or registration has been made (17 U.S.C. 411(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.
Federal District Courts and Where They Sit
Under 28 U.S.C. 1338(a), the federal district courts have original jurisdiction over patent, plant variety protection, copyright, and trademark claims, and that jurisdiction is exclusive for patents, plant variety protection, and copyrights. A trademark claim can also be brought in state court.
By statute the state has three federal districts, known as the Eastern, Middle, and Western Districts of Louisiana (28 U.S.C. 98). A federal case from Eunice is filed in the Western District of Louisiana, where court is held at Alexandria, Lafayette, Lake Charles, Monroe, Opelousas, and Shreveport. Because Eunice lies in more than one county, it is worth confirming which county the matter falls in.
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 Eunice may also raise a claim under the Uniform Trade Secrets Act (La. R.S. 51:1431 to 51:1439). Which claims fit depends on the facts.
Federal trademark law under 15 U.S.C. 1114 and 1125 sits alongside Louisiana’s registration system, which runs through the Louisiana Secretary of State under La. R.S. 51:211 and following sections. The two operate separately.
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.
Common Intellectual Property Claims
Patent Infringement
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.
Both patent owners and people accused of infringing should collect the patent number, product samples, and dates early.
Confusing Similarity and Brand Protection
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)).
A state registration in Louisiana (La. R.S. 51:211 and following sections) is different from federal registration on the principal register (15 U.S.C. 1051).
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)).
Federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)).
Confidential Information and Departing Employees
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 Uniform Trade Secrets Act (La. R.S. 51:1431 to 51:1439) may provide state-law claims alongside the federal action, with their own deadlines.
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).
In trademark cases, courts have the power to enjoin violations (15 U.S.C. 1116(a)), and a plaintiff who establishes a violation may recover profits, damages, and costs, subject to sections 1111 and 1114 and the principles of equity (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.
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.
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.

Frequently Asked Questions
What can be patented?
A new and useful process, machine, manufacture, or composition of matter may be patented, subject to the conditions and requirements of the patent statute (35 U.S.C. 101).
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)).
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)).
Where does the federal court for Eunice hold court?
The Western District of Louisiana holds court in Alexandria, Lafayette, Lake Charles, Monroe, Opelousas, and Shreveport (28 U.S.C. 98).
Does state registration replace federal registration?
No. A state registration, where one is available, is a separate filing from federal registration on the principal register (15 U.S.C. 1051), and each operates on its own.
What are the main deadlines in intellectual property cases?
Copyright: three years from accrual (17 U.S.C. 507(b)). Federal trade secrets: three years from discovery (18 U.S.C. 1836(d)). Patent damages: no recovery for infringement more than six years before the complaint (35 U.S.C. 286).
How do I keep information as a trade secret?
Take reasonable measures to keep it secret, because that is one of the two elements of the definition (18 U.S.C. 1839(3)), and consult an attorney about what measures are reasonable for your business.
