Your El Dorado 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 El Dorado. Below you will find the key deadlines at a glance, what each type of protection covers, the steps that come before a lawsuit, which federal court hears a case from Butler County, and how Kansas law fits alongside federal law. The facts of your situation decide which area of law controls, and an attorney who practices in federal court can sort that out quickly.
Your Key Federal and Kansas Rules in One Place
- 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).
- Even an unregistered mark can be protected against false designation of origin, through a civil action by anyone who believes they are likely to be damaged (15 U.S.C. 1125(a)(1)).
- 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)).
- 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)).
- The federal court for El Dorado is the District of Kansas, with court held at Kansas City, Lawrence, Leavenworth, Salina, Topeka, Hutchinson, Wichita, Dodge City, and Fort Scott (28 U.S.C. 96).
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)).
Under 15 U.S.C. 1127, a trademark is any word, name, symbol, or device, or a combination, that identifies and distinguishes one person’s goods from another’s and indicates their source, and a service mark performs that function for 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)).
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.
Trade secrets: a federal action under the Defend Trade Secrets Act may not be commenced later than 3 years after the misappropriation is discovered or, with reasonable diligence, should have been discovered, and a continuing misappropriation counts 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 Kansas state-law claim brings its own deadline and its own accrual rule. Both come from Kansas statutes and court decisions and should be reviewed by an attorney at the start of the matter.

Registration Steps for Trademarks and Copyrights
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)).
Federal registration is not the only route. Kansas’s trademark registration provisions, Article 2 of K.S.A. chapter 81, provide for a state filing with the Kansas Secretary of State that operates separately from the federal register.
Owners of creative work should know that registration is a precondition to suing on a United States work (17 U.S.C. 411(a)), and that the duration for most later works is the life of the author plus 70 years (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.
Under 28 U.S.C. 96, Kansas is one federal judicial district, and Butler County is part of it. The District of Kansas holds court in Kansas City, Lawrence, Leavenworth, Salina, Topeka, Hutchinson, Wichita, Dodge City, and Fort Scott.
What Kansas Law Can Add to Federal Protection
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 Kansas Uniform Trade Secrets Act (K.S.A. 60-3320 to 60-3330). The state and federal claims are separate.
Federal trademark law under 15 U.S.C. 1114 and 1125 sits alongside Kansas’s registration system, which runs through the Kansas Secretary of State under Article 2 of K.S.A. chapter 81. The two operate separately.
Which claims to bring, and in which court, is a strategy question for an attorney who can read the documents.
What Kinds of Intellectual Property Cases Come Up?
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.
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
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.
A state registration in Kansas (Article 2 of K.S.A. chapter 81) is different from federal registration on the principal register (15 U.S.C. 1051).
Protecting Creative Work
Whether copying is actionable begins with what is protected. Copyright subsists in original works fixed in a tangible medium (17 U.S.C. 102(a)) and does not reach ideas, procedures, processes, systems, or methods of operation (17 U.S.C. 102(b)).
The duration of a copyright for a work created on or after January 1, 1978 is generally the life of the author plus 70 years (17 U.S.C. 302(a)).
Protecting Confidential Business Information
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)).
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).
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)).
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)).
Under 17 U.S.C. 412, an owner who registers after an infringement has started may lose access to statutory damages and attorney’s fees for that infringement, unless the work was published and registered within three months of first publication.
The Defend Trade Secrets Act lists the remedies: an injunction, damages for actual loss and unjust enrichment (or a reasonable royalty), exemplary damages of not more than 2 times the damages for willful and malicious misappropriation, and attorney’s fees in the situations the statute names (18 U.S.C. 1836(b)(3)).

What an Attorney Will Want to See
Before you talk to anyone, list the key dates in order. Copyright and federal trade secret deadlines run from accrual and discovery, and patent damages look back from the complaint, so a clean timeline shows where you stand.
For a patent question, bring drawings, notes, prototypes, any patent or application numbers, and information about who has seen or used the invention. For a trademark, bring the name or logo, examples of how it is used, and any registration papers.
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.

Yes, if the trade secret is related to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)). The federal district courts have original jurisdiction of these actions (18 U.S.C. 1836(c)).

How do I know whether I need a patent, trademark, copyright, or trade secret protection?
It depends on what you are protecting: an invention (35 U.S.C. 101), a name or logo that identifies goods or services (15 U.S.C. 1127), original creative work (17 U.S.C. 102(a)), or confidential information (18 U.S.C. 1839(3)).
