Your Townsend 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 Delaware rules that most often decide how an intellectual property matter from Townsend unfolds. This page covers the deadlines, the definitions that decide whether something is protected, the federal district court for New Castle County, and the Delaware rules that sit next to the federal ones. These rules apply across Delaware, and an attorney familiar with the District of Delaware can explain what to expect there.
Quick Answers on Patents, Trademarks, Copyrights, and Trade Secrets
- 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 Delaware. The federal register is set up by 15 U.S.C. 1051, and state registration is filed with the Delaware Secretary of State under Chapter 33 of Title 6 of the Delaware Code.
- 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)).
- Federal district: for New Castle County, the District of Delaware under 28 U.S.C. 87, holding court in Wilmington.
Which Type of Protection Fits Your Situation
For an invention, the question is whether it fits one of the four categories in 35 U.S.C. 101, and if a patent is granted, it lasts for 20 years measured from the application filing date (35 U.S.C. 154(a)(2)).
Names, logos, and slogans that tell customers who is behind a product are trademarks, defined in 15 U.S.C. 1127 as any word, name, symbol, or device used to identify and distinguish a person’s goods and to indicate their source. A service mark does the same job for 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)).
Business and technical information such as plans, formulas, and processes qualifies as a trade secret only if the owner has taken reasonable measures to keep it secret and it derives independent economic value from secrecy (18 U.S.C. 1839(3)).
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.
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)).
The federal deadlines above do not decide state-law claims. Delaware sets its own limitation periods and accrual rules, and an attorney can tell you which apply to a trade secret or unfair competition claim brought under state law.

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)).
In addition to the federal register, a business in Delaware can file for a state trademark registration with the Delaware Secretary of State (see Chapter 33 of Title 6 of the Delaware Code). The state filing is a separate process from the federal application.
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)).
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.
The Federal Court for New Castle County
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.
The federal court for Townsend is the District of Delaware, which covers all of Delaware (28 U.S.C. 87) and holds court in Wilmington.
Delaware Law Alongside Federal Law
Trade secret claims are not only federal. The Delaware Uniform Trade Secrets Act (6 Del. C. 2001 and following sections) 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)).
Beyond the federal Lanham Act, a brand owner in Townsend can look to Delaware’s own trademark registration system. Filings are made with the Delaware Secretary of State under Chapter 33 of Title 6 of the Delaware Code, 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.
The Claims Behind Most Intellectual Property Disputes
Patent Claims and Defenses
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)).
Damages are limited to infringement within the six years before the complaint (35 U.S.C. 286).
Confusing Similarity and Brand Protection
Even without registration, the Lanham Act allows a civil action against anyone who uses in commerce a word, term, name, symbol, or device likely to cause confusion or deceive about affiliation, connection, or origin (15 U.S.C. 1125(a)(1)), brought by a person who believes he or she is or is likely to be damaged.
State trademark registration in Delaware is filed with the Delaware Secretary of State under Chapter 33 of Title 6 of the Delaware Code, separate from the federal statutes.
Copyright Claims
For writing, images, music, or film, copyright protects the original expression fixed in a tangible medium (17 U.S.C. 102(a)) but never the underlying idea (17 U.S.C. 102(b)).
Keeping dated copies of drafts and finished work helps show what was created and when.
Disputes Over Trade Secrets
Trade secret cases often turn on whether the owner took reasonable measures to keep the information secret and whether it has independent economic value from not being generally known, the two elements of 18 U.S.C. 1839(3).
The federal action has a three-year deadline running from discovery, or from when reasonable diligence should have led to discovery (18 U.S.C. 1836(d)).
Damages, Injunctions, and Other Relief
Relief in a patent case can include damages of at least a reasonable royalty with interest and costs, and enhancement up to three times in the court’s discretion (35 U.S.C. 284), and an injunction on reasonable terms under the principles of equity (35 U.S.C. 283).
In trademark cases, courts have the power to enjoin violations (15 U.S.C. 1116(a)), and a plaintiff who establishes a violation may recover profits, damages, and costs, subject to sections 1111 and 1114 and the principles of equity (15 U.S.C. 1117(a)).
A copyright owner can choose between actual damages plus the infringer’s profits attributable to the infringement, and statutory damages (17 U.S.C. 504(a), (b)), and statutory damages range from $750 to $30,000 per work as the court considers just (17 U.S.C. 504(c)(1)).
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)).

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.
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.
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.

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 Delaware trademark registration?
Federal registration is on the principal register through the Patent and Trademark Office (15 U.S.C. 1051). Delaware registration is a separate filing made with the Delaware Secretary of State under Chapter 33 of Title 6 of the Delaware Code, and it does not replace the federal one.
Do I have to register a copyright before I sue?
For a United States work, yes. No civil action for infringement of the copyright may be instituted until preregistration or registration of the copyright claim has been made (17 U.S.C. 411(a)), with a provision for cases where registration was refused.
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.
Do I have to file in federal court?
For patents and copyrights, yes: the federal jurisdiction is exclusive (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court, and a federal trade secret action is filed in federal district court (18 U.S.C. 1836(c)).
Can a trademark claim be brought under Delaware law?
Possibly. Delaware law may provide trademark claims of its own alongside the federal ones, and which apply depends on the mark and the facts. An attorney can explain the options.
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)).
