Your Derby Intellectual Property Attorney
If you are trying to protect an invention, a brand, or a creative work in Derby, or you have been accused of infringing someone else’s, you probably want plain answers about deadlines, courts, and what each kind of protection covers. Federal statutes set most of them, so many answers can be checked. 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. These rules apply across Kansas, and an attorney familiar with the District of Kansas can explain what to expect there.
The Short Answers: Deadlines, Courts, and Protection
- 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.
- Trademark claims can go to federal or state court (28 U.S.C. 1338(a)), and Kansas’s own registration is a separate filing with the Kansas Secretary of State.
- Copyright lawsuits have a three-year clock from when the claim accrued (17 U.S.C. 507(b)), and a United States work must be registered before an infringement suit can be filed (17 U.S.C. 411(a)).
- Kansas has its own trade secret statute, the Kansas Uniform Trade Secrets Act (K.S.A. 60-3320 to 60-3330), and the federal action in 18 U.S.C. 1836 sits alongside it.
- A federal case from Derby goes to the District of Kansas (28 U.S.C. 96), which sits in Kansas City, Lawrence, Leavenworth, Salina, Topeka, Hutchinson, Wichita, Dodge City, and Fort Scott.
What Patents, Trademarks, Copyrights, and Trade Secrets Protect
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.
Writing, music, images, film, software text, and similar creative work are the subject of copyright, which subsists in original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)). The statute is equally clear about what is excluded: ideas, procedures, processes, systems, methods of operation, concepts, principles, and discoveries (17 U.S.C. 102(b)).
Unlike a patent, a trade secret is kept private. The federal definition requires reasonable secrecy measures and independent economic value from not being generally known or readily ascertainable through proper means (18 U.S.C. 1839(3)).
How Long Do You Have to Bring a Claim?
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)).
The federal trade secret deadline is set by 18 U.S.C. 1836(d): three years from the date the misappropriation was discovered or by the exercise of reasonable diligence should have been discovered, with continuing misappropriation counted as one claim.
Patent infringement damages reach back at most six years before the complaint (35 U.S.C. 286), so a suspected infringement is worth reviewing promptly.
State-law claims, such as a claim under the Kansas Uniform Trade Secrets Act (K.S.A. 60-3320 to 60-3330) or a state trademark claim, have their own rules on limitation periods and on when a claim begins to run. Those are set by Kansas statutes and court decisions, so the dates should be checked by an attorney rather than assumed from the federal deadlines.

What to Do Before a Dispute Starts
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.
A Kansas business can ask an attorney whether a state-level trademark filing with the Kansas Secretary of State is worth adding to a federal application. The provisions are in Article 2 of K.S.A. chapter 81, and the two registrations are separate.
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)).
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.
Where an Intellectual Property Case From Derby Is Filed
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 Sedgwick 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
Trade secret claims are not only federal. The Kansas Uniform Trade Secrets Act (K.S.A. 60-3320 to 60-3330) may apply to the same facts, and the federal statute provides its own 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)).
Beyond the federal Lanham Act, a brand owner in Derby can look to Kansas’s own trademark registration system. Filings are made with the Kansas Secretary of State under Article 2 of K.S.A. chapter 81, and a state filing does not replace a federal application.
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 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.
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.
Confusing Similarity and Brand Protection
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.
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)).
Keeping dated copies of drafts and finished work helps show what was created and when.
Confidential Information and Departing Employees
The federal claim in 18 U.S.C. 1836(b)(1) is limited to trade secrets connected to interstate or foreign commerce, and the information must satisfy 18 U.S.C. 1839(3) to count as a trade secret at all.
Documents showing who had access, and what confidentiality steps existed, are among the first things to preserve.
Remedies in Intellectual Property Cases
For patents, 35 U.S.C. 284 sets the damages floor at a reasonable royalty and lets the court increase damages up to three times the amount found or assessed, and 35 U.S.C. 283 allows injunctions according to the principles of equity, on terms the court considers reasonable.
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)).
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)).
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)).

Preparing for a First Conversation
Write down a short timeline before the call: when the work or invention was made, when it was first shown to anyone, and when you learned of the problem. The federal deadlines above are measured from dates like these.
Patent matters go faster with drawings, lab notes, patent or application numbers, and a list of who has seen the invention. Trademark matters go faster with the mark itself, samples of its use, and any registration documents.
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
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).
Does an unregistered brand have any protection?
Possibly. A civil action can be brought under 15 U.S.C. 1125(a)(1) by a person who believes he or she is or is likely to be damaged by a false designation of origin likely to cause confusion, and Kansas law may offer additional protection.
What kinds of work does copyright cover?
Original works of authorship fixed in any tangible medium of expression (17 U.S.C. 102(a)), including literary, musical, dramatic, and pictorial works, motion pictures, sound recordings, and architectural works.
Can I sue in federal court over a stolen trade secret?
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)).
Which federal court covers Derby?
The District of Kansas (28 U.S.C. 96).
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.
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).
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)).
