Your Watertown 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 Dakota rules that most often decide how an intellectual property matter from Watertown unfolds. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for Codington County, South Dakota’s own trademark and trade secret rules, and what an infringement claim involves. 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
- 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).
- Even an unregistered mark can be protected against false designation of origin, through a civil action by anyone who believes they are likely to be damaged (15 U.S.C. 1125(a)(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.
- 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)).
- The federal court for Watertown is the District of South Dakota, with court held at Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City (28 U.S.C. 122).
Patents, Trademarks, Copyrights, and Trade Secrets Compared
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.
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)).
A trade secret is 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)). The statute covers financial, business, scientific, and technical information such as patterns, plans, formulas, designs, methods, processes, programs, and codes.
Filing Deadlines and Damages Limits
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.
Discovery drives the trade secret clock. A civil action under 18 U.S.C. 1836(b) may not be commenced later than three years after the misappropriation is, or by reasonable diligence should be, discovered (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)).
Claims under South Dakota law carry their own limitation periods and their own rules for when the clock starts, which are different questions from the federal deadlines in this section. Have the dates checked before relying on any of them.

What to Do Before a Dispute Starts
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 Dakota’s trademark registration provisions, SDCL chapter 37-6, provide for a state filing with the South Dakota Secretary of State that operates separately from the federal register.
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)).
Inventors should keep the 20-year term measured from filing in mind (35 U.S.C. 154(a)(2)), and should confirm early with an attorney that the invention falls within 35 U.S.C. 101.
Which Court Handles a Claim From Watertown
Under 28 U.S.C. 1338(a), the federal district courts have original jurisdiction over patent, plant variety protection, copyright, and trademark claims, and that jurisdiction is exclusive for patents, plant variety protection, and copyrights. A trademark claim can also be brought in state court.
There is only one federal district in South Dakota. The District of South Dakota hears federal cases from Codington County and holds court in Aberdeen, Sioux Falls, Pierre, Deadwood, and Rapid City (28 U.S.C. 122).
How South Dakota Law Fits In
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 (SDCL 37-29-1 to 37-29-11). The state and federal claims are separate.
A brand owner in Watertown may have state-law options in addition to federal ones. South Dakota’s trademark registration provisions are found in SDCL chapter 37-6, and the filing office is the South Dakota Secretary of State.
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
Claims That a Patent Is Being Infringed
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)).
A patent case is filed in federal district court (28 U.S.C. 1338(a)).
Trademark Infringement and Brand Disputes
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.
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
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)).
Confidential Information and Departing Employees
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 (SDCL 37-29-1 to 37-29-11) may provide state-law claims alongside the federal action, with their own deadlines.
Remedies in Intellectual Property Cases
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).
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.
The copyright statute offers two routes to money relief: actual damages and profits (17 U.S.C. 504(b)) or statutory damages of not less than $750 or more than $30,000 for infringements of any one work (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)).

Preparing for a First Conversation
An attorney will usually begin with dates: creation, first disclosure, first use in commerce, first publication, and discovery of the problem. Gathering them ahead of time saves a first meeting for the questions that matter.
If the issue is a patent, gather technical drawings, descriptions, and any application numbers. If it is a trademark, gather the mark, examples of use, and registration information.
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
How long does a patent last?
A patent lasts 20 years from the date the application was filed in the United States (35 U.S.C. 154(a)(2)), so the filing date, not the issue date, sets the end of the term.
What is the difference between federal and South Dakota trademark registration?
Federal registration is on the principal register through the Patent and Trademark Office (15 U.S.C. 1051). South Dakota registration is a separate filing made with the South Dakota Secretary of State under SDCL chapter 37-6, and it does not replace the federal one.
How long do I have to sue for copyright infringement?
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
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.
Which court handles patent and copyright cases from Watertown?
Both belong exclusively in federal district court (28 U.S.C. 1338(a)), which for Watertown means the District of South Dakota.
Can I bring both federal and South Dakota claims?
Often yes. A dispute can involve federal claims, such as under 15 U.S.C. 1114 or 18 U.S.C. 1836, and state-law claims under South Dakota law. An attorney can advise which to bring.
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)).
