An attorney who handles intellectual property matters can tell you which of these rules apply to your situation.
Your Key Federal and Tennessee Rules in One Place
- 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)).
- Trademarks can be registered federally and in Tennessee. The federal register is set up by 15 U.S.C. 1051, and state registration is filed with the Tennessee Secretary of State under the Tennessee Trade Mark Act of 2000, Tenn. Code 47-25-501 to 47-25-518.
- How long does a copyright last? For works created on or after January 1, 1978, the life of the author plus 70 years (17 U.S.C. 302(a)), with different counts for joint works and works made for hire.
- 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)).
- A federal case from Ripley goes to the Western District of Tennessee (28 U.S.C. 123), which sits in Jackson, Dyersburg, and Memphis.
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)).
If the issue is a business name, logo, or slogan, the question is trademark, which the Lanham Act defines as a word, name, symbol, or device that identifies and distinguishes goods and indicates their source (15 U.S.C. 1127), with service marks covering 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)).
Trade secret protection depends on two things: the owner took reasonable measures to keep the information secret, and the information has independent economic value because it is not generally known or readily ascertainable (18 U.S.C. 1839(3)). Formulas, methods, processes, programs, and codes can all qualify.
Why Timing Matters in Intellectual Property Disputes
Copyright: a civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)). Because a United States work must also be registered before an infringement suit can be filed (17 U.S.C. 411(a)), the registration step should not be left until after the dispute begins.
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)).
Patents: there is no recovery for infringement committed more than six years before the filing of the complaint or counterclaim for infringement (35 U.S.C. 286). Waiting can therefore shrink the damages available even when the patent itself is still in force.
State-law claims, such as a claim under the Uniform Trade Secrets Act (Tenn. Code 47-25-1701 to 47-25-1709) or a state trademark claim, have their own rules on limitation periods and on when a claim begins to run. Those are set by Tennessee statutes and court decisions, so the dates should be checked by an attorney rather than assumed from the federal deadlines.

Registering and Protecting Your Rights
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)).
Tennessee also has its own trademark registration. A state filing is made with the Tennessee Secretary of State under the Tennessee Trade Mark Act of 2000, Tenn. Code 47-25-501 to 47-25-518, is separate from the federal register, and does not replace a federal application.
A copyright owner cannot file an infringement action on a United States work before registration has been made (17 U.S.C. 411(a)), although a refusal of registration can also open the door to suit if the Register of Copyrights is notified and served with the complaint.
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
In practice, patent and copyright disputes are filed in federal district court (28 U.S.C. 1338(a)), federal trade secret claims start there as well (18 U.S.C. 1836(c)), and a trademark dispute can be filed in federal or state court.
By statute the state has three federal districts, known as the Eastern, Middle, and Western Districts of Tennessee (28 U.S.C. 123). A federal case from Ripley is filed in the Western District of Tennessee, where court is held at Jackson, Dyersburg, and Memphis.
What Tennessee 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 Uniform Trade Secrets Act (Tenn. Code 47-25-1701 to 47-25-1709). The state and federal claims are separate.
Trademark protection has a state layer as well. A state trademark registration in Tennessee is filed with the Tennessee Secretary of State under the Tennessee Trade Mark Act of 2000, Tenn. Code 47-25-501 to 47-25-518, and it is separate from federal registration on the principal register (15 U.S.C. 1051).
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?
Using an Invention Without Permission
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
Two federal provisions do most of the work in trademark cases: 15 U.S.C. 1114(1)(a) for registered marks and 15 U.S.C. 1125(a)(1) for misleading uses of any word, term, name, symbol, or device, registered or not.
Trademark claims may be filed in federal court or in state court (28 U.S.C. 1338(a)).
Copying of Creative Work
Creative disputes involve two threshold points: the work must be an original work of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and the claim cannot rest on an idea or system (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)).
Protecting Confidential Business Information
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 (Tenn. Code 47-25-1701 to 47-25-1709) may provide state-law claims alongside the federal action, with their own deadlines.
Injunctions and Money Damages by Type of Claim
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).
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)).
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 to Gather Before You Talk to an Attorney
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.
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.
Creators should bring the work itself, dated drafts, and examples of the copy. Owners of confidential information should bring a description of it, a list of who had access, and the steps taken to keep it secret.

Frequently Asked Questions
Where is a patent infringement case filed?
In federal district court. The district courts have original jurisdiction of civil actions arising under patent law, and that jurisdiction is exclusive (28 U.S.C. 1338(a)). For Ripley, that is the Western District of Tennessee.
Can I register my business name or logo as a trademark?
A word, name, symbol, or device used to identify and distinguish goods and indicate their source is a trademark (15 U.S.C. 1127), and the owner of a mark used in commerce may request federal registration (15 U.S.C. 1051(a)(1)).
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 if a former employee took confidential information?
That can be a trade secret claim if the information meets the definition in 18 U.S.C. 1839(3), and the federal deadline is three years from discovery (18 U.S.C. 1836(d)). An attorney can review what was taken and what protections were in place.
Are trade secret cases filed in federal court?
A federal trade secret action under 18 U.S.C. 1836 is filed in federal district court (18 U.S.C. 1836(c)), and Tennessee state-law claims are separate claims.
Do federal deadlines apply to Tennessee state-law claims?
Not automatically. Tennessee state-law claims have their own limitation periods and accrual rules, set by Tennessee statutes and court decisions, and an attorney should check them.
When does the trade secret clock start?
From the date the misappropriation is discovered or, by reasonable diligence, should have been discovered (18 U.S.C. 1836(d)).
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)).
