Your Mount Pleasant Intellectual Property Attorney
Finding out that someone is using your invention, your name, or your creative work without permission is unsettling. This page explains the federal and South Carolina rules that most often decide how an intellectual property matter from Mount Pleasant unfolds. This page covers the deadlines, the definitions that decide whether something is protected, the federal district court for Charleston County, and the South Carolina rules that sit next to the federal ones. An attorney who handles intellectual property matters can tell you which of these rules apply to your situation.
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 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)).
- 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)).
- Where is my case filed? Mount Pleasant is in the District of South Carolina, and that court holds court in Charleston, Columbia, Florence, Aiken, Orangeburg, Greenville, Rock Hill, Greenwood, Anderson, Spartanburg, and Beaufort (28 U.S.C. 121).
The Four Main Areas of Intellectual Property Law
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.
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.
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)).
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
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)).
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 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.

Steps That Strengthen a Claim Before It Is Needed
Registration on the federal principal register begins with an application and verified statement. The statute allows the owner of a mark used in commerce to apply (15 U.S.C. 1051(a)(1)) and separately a person with a bona fide intention to use (15 U.S.C. 1051(b)(1)).
Federal registration is not the only route. South Carolina’s trademark registration provisions, Chapter 15 of Title 39 of the South Carolina Code, provide for a state filing with the South Carolina Secretary of State that operates separately from the federal register.
Registering a copyright before there is a dispute avoids a delay later. The statute says no civil action for infringement of the copyright in a United States work may be instituted until preregistration or registration has been made (17 U.S.C. 411(a)).
The application date controls the length of patent protection, which ends 20 years after filing (35 U.S.C. 154(a)(2)), so planning the filing is part of protecting the invention.
Federal District Courts and Where They Sit
The choice of court depends on the type of claim. Patent and copyright cases can only be filed in federal district court (28 U.S.C. 1338(a)), a federal trade secret action is filed in federal district court (18 U.S.C. 1836(c)), and trademark claims can go to federal or state court.
Under 28 U.S.C. 121, South Carolina is one federal judicial district, and Charleston County is part of it. The District of South Carolina holds court in Charleston, Columbia, Florence, Aiken, Orangeburg, Greenville, Rock Hill, Greenwood, Anderson, Spartanburg, and Beaufort.
How South Carolina Law Fits In
Trade secret claims are not only federal. The South Carolina Trade Secrets Act (S.C. Code 39-8-10 to 39-8-130) 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)).
A state trademark registration in South Carolina is a different filing from federal registration (15 U.S.C. 1051). It is made with the South Carolina Secretary of State under Chapter 15 of Title 39 of the South Carolina Code.
Choosing between state and federal claims, or bringing both, is something an attorney should decide after reviewing what happened and what proof exists.
The Basics of Each Type of Claim
Claims That a Patent Is Being Infringed
Patent disputes turn on the patent’s claims and on conduct listed in 35 U.S.C. 271(a), namely making, using, offering to sell, selling, or importing a patented invention without authority.
Damages are limited to infringement within the six years before the complaint (35 U.S.C. 286).
Trademark and Unfair Competition 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 person who believes he or she is or is likely to be damaged can bring the civil action under 15 U.S.C. 1125(a)(1).
Protecting 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)).
Disputes Over Trade Secrets
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).
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
Damages, Injunctions, and Other Relief
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.
For a misappropriated trade secret, 18 U.S.C. 1836(b)(3) authorizes an injunction against actual or threatened misappropriation, damages for actual loss and unjust enrichment or a reasonable royalty, exemplary damages up to 2 times for willful and malicious misappropriation, and reasonable attorney’s fees to the prevailing party in stated situations.

Preparing for a First Conversation
Start with the basics: what you created or invented, who was involved, and when each step happened. Dates matter because the deadlines described above run from events such as accrual of a claim, discovery of a misappropriation, or the filing of an application.
Inventors should collect drawings, notes, and application numbers, and brand owners should collect the mark, examples of use, and any registration papers, before the first conversation.
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.
