If you are trying to protect an invention, a brand, or a creative work in Lake City, 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.

These rules apply across South Carolina, and an attorney familiar with the District of South Carolina can explain what to expect there.
Quick Answers on Patents, Trademarks, Copyrights, and Trade Secrets
- 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).
- Federal trademark registration is available to the owner of a mark used in commerce or to a person with a bona fide intention to use one (15 U.S.C. 1051(a)(1), (b)(1)).
- 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.
- South Carolina has its own trade secret statute, the South Carolina Trade Secrets Act (S.C. Code 39-8-10 to 39-8-130), and the federal action in 18 U.S.C. 1836 sits alongside it.
- Which court? A case from Lake City that belongs in federal court is filed in the District of South Carolina, which holds court in Charleston, Columbia, Florence, Aiken, Orangeburg, Greenville, Rock Hill, Greenwood, Anderson, Spartanburg, and Beaufort.
The Four Main Areas of Intellectual Property Law
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 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.
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)).
Filing Deadlines and Damages Limits
For copyright infringement, the statute sets three years from when the claim accrued (17 U.S.C. 507(b)), and registration or a refusal of registration must come before suit on a United States work (17 U.S.C. 411(a)).
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)).
A patent owner who waits loses damages: under 35 U.S.C. 286, no recovery may be had for infringement committed more than six years before the complaint. The patent itself lasts 20 years from filing (35 U.S.C. 154(a)(2)).
State-law claims, such as a claim under the South Carolina Trade Secrets Act (S.C. Code 39-8-10 to 39-8-130) or a state trademark claim, have their own rules on limitation periods and on when a claim begins to run. Those are set by South Carolina 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
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)).
A South Carolina business can ask an attorney whether a state-level trademark filing with the South Carolina Secretary of State is worth adding to a federal application. The provisions are in Chapter 15 of Title 39 of the South Carolina Code, and the two registrations are separate.
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)).
The filing date is what starts the patent clock (35 U.S.C. 154(a)(2)), so the timing of an application matters. An attorney can advise whether the invention fits the categories in 35 U.S.C. 101.
Where an Intellectual Property Case From Lake City 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.
South Carolina constitutes one federal judicial district, the District of South Carolina (28 U.S.C. 121), so a federal case from Lake City is filed there. The court holds court in Charleston, Columbia, Florence, Aiken, Orangeburg, Greenville, Rock Hill, Greenwood, Anderson, Spartanburg, and Beaufort.
What South Carolina Law Can Add to Federal Protection
Owners of confidential information in Lake City can look to two sources: the South Carolina Trade Secrets Act (S.C. Code 39-8-10 to 39-8-130) and the federal action in 18 U.S.C. 1836(b), which requires a connection to interstate or foreign commerce and has its own three-year deadline (18 U.S.C. 1836(d)).
A brand owner in Lake City may have state-law options in addition to federal ones. South Carolina’s trademark registration provisions are found in Chapter 15 of Title 39 of the South Carolina Code, and the filing office is the South Carolina Secretary of State.
The details of a state-law claim depend on the facts, and an attorney can explain which of the federal and state claims fit a particular dispute.
Common Intellectual Property Claims
Claims That a Patent Is Being Infringed
Whether conduct is infringement is measured against 35 U.S.C. 271(a), which reaches anyone who, without authority, makes, uses, offers to sell, or sells a patented invention in the United States or imports it during the patent’s 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.
Trademark and Unfair Competition Claims
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.
A state registration in South Carolina (Chapter 15 of Title 39 of the South Carolina Code) is different from federal registration on the principal register (15 U.S.C. 1051).
Copying of Creative Work
In a copyright case, the first questions are whether the work is protected at all under 17 U.S.C. 102(a) and whether what was copied was protected expression rather than an idea or method excluded by 17 U.S.C. 102(b).
Federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(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)).
A continuing misappropriation is treated as a single claim for the federal deadline (18 U.S.C. 1836(d)).
What a Successful Claim Can Recover
Patent: a court that finds for the claimant shall award damages adequate to compensate for the infringement, but in no event less than a reasonable royalty for the use made of the invention, together with interest and costs, and the court may increase the damages up to three times the amount found or assessed (35 U.S.C. 284). Courts may also grant injunctions in accordance with the principles of equity to prevent the violation of a patent right (35 U.S.C. 283).
The trademark remedies are set out in 15 U.S.C. 1116(a), which gives courts the power to grant injunctions, and 15 U.S.C. 1117(a), which lets a plaintiff recover defendant’s profits, damages, and costs once a violation is established.
Copyright damages can be measured by the owner’s actual damages and the infringer’s attributable profits (17 U.S.C. 504(b)), or by statutory damages between $750 and $30,000 per work as the court considers just (17 U.S.C. 504(c)(1)).
Delay in registering can cost more than time. Infringement that starts before the effective date of registration generally cannot support statutory damages or attorney’s fees, with the exception in 17 U.S.C. 412 for registration within three months after first publication.
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)).

What an Attorney Will Want to See
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.
For copyright, gather the work, drafts with dates, and examples of copying. For a trade secret, gather what the information is, who could see it, and what confidentiality agreements or security measures applied.
