Your Ames Intellectual Property Attorney
A patent, a trademark, a copyright, and a trade secret are four different things with four different sets of rules. For an Ames business, artist, or inventor, the first step is knowing which one is actually involved, and this page walks through how to tell. 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 Iowa, and an attorney familiar with the Southern District of Iowa can explain what to expect there.
The Short Answers: Deadlines, Courts, and Protection
- 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)).
- 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)).
- The trade secret clock runs from discovery: three years from when the misappropriation was, or with reasonable diligence should have been, discovered (18 U.S.C. 1836(d)).
- The federal court for Ames is the Southern District of Iowa, with court held at Des Moines, Keokuk, Council Bluffs, Creston, Davenport, and Ottumwa (28 U.S.C. 95).
What Patents, Trademarks, Copyrights, and Trade Secrets Protect
Patents cover new and useful processes, machines, manufactures, and compositions of matter (35 U.S.C. 101). Protection lasts until 20 years after the date on which the application was filed in the United States (35 U.S.C. 154(a)(2)), so the filing date matters more than the date the patent issues.
A brand is protected as a trademark when it functions to identify and distinguish goods from those of others and to indicate the source of the goods (15 U.S.C. 1127). The same statute defines a service mark for the source of 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)).
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.
Time Limits That Matter in Patent, Copyright, and Trade Secret Cases
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)).
State-law claims, such as a claim under the Uniform Trade Secrets Act (Iowa Code chapter 550) or a state trademark claim, have their own rules on limitation periods and on when a claim begins to run. Those are set by Iowa statutes and court decisions, so the dates should be checked by an attorney rather than assumed from the federal deadlines.

Steps That Strengthen a Claim Before It Is Needed
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.
State registration is a different filing from a federal application. In Iowa it is made with the Iowa Secretary of State under Iowa Code chapter 548, and an attorney can tell you whether a state filing, a federal filing, or both suit your plans.
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.
The Federal Court for Story County
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.
By statute the state has two federal districts, known as the Northern and Southern Districts of Iowa (28 U.S.C. 95). A federal case from Ames is filed in the Southern District of Iowa, where court is held at Des Moines, Keokuk, Council Bluffs, Creston, Davenport, and Ottumwa.
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 (Iowa Code chapter 550). The state and federal claims are separate.
Beyond the federal Lanham Act, a brand owner in Ames can look to Iowa’s own trademark registration system. Filings are made with the Iowa Secretary of State under Iowa Code chapter 548, and a state filing does not replace a federal application.
Choosing between state and federal claims, or bringing both, is something an attorney should decide after reviewing what happened and what proof exists.
Common Intellectual Property Claims
Patent Infringement
Infringement occurs when someone, without authority, makes, uses, offers to sell, or sells any patented invention within the United States, or imports a patented invention into the United States, during the term of the patent (35 U.S.C. 271(a)).
Because the six-year damages limit in 35 U.S.C. 286 runs back from the complaint, delay can reduce what is recoverable.
Disputes Over Names, Logos, and Brands
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 Iowa (Iowa Code chapter 548) 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)).
For a United States work, registration must be made before an infringement suit is instituted (17 U.S.C. 411(a)).
Trade Secret Claims
In a trade secret dispute, both sides examine the same two things: the steps the owner took to keep the information secret and the value that comes from its not being generally known or readily ascertainable (18 U.S.C. 1839(3)).
The Uniform Trade Secrets Act (Iowa Code chapter 550) may provide state-law claims alongside the federal action, with their own deadlines.
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.
A brand owner who establishes a violation may recover the defendant’s profits, damages sustained, and costs (15 U.S.C. 1117(a)), and can ask the court for an injunction to stop the violation (15 U.S.C. 1116(a)), both subject to the principles of equity.
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.
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)).

Preparing for a First Conversation
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.
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
What counts as patent infringement?
Without authority, making, using, offering to sell, or selling a patented invention in the United States, or importing one into the United States, during the term of the patent (35 U.S.C. 271(a)).
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 Iowa 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.
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 Ames?
The Southern District of Iowa (28 U.S.C. 95).
Do federal deadlines apply to Iowa state-law claims?
Not automatically. Iowa state-law claims have their own limitation periods and accrual rules, set by Iowa statutes and court decisions, and an attorney should check them.
Is there a deadline to sue for patent infringement?
Patent damages reach back six years before the complaint (35 U.S.C. 286), so delay can reduce recovery even while the patent is in force.
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).
