Your Elsmere Intellectual Property Attorney
If you are trying to protect an invention, a brand, or a creative work in Elsmere, 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. Federal statutes set most of them, so many answers can be checked. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for New Castle County, Delaware’s own trademark and trade secret rules, and what an infringement claim involves. The facts of your situation decide which area of law controls, and an attorney who practices in federal court can sort that out quickly.
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)).
- 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.
- Delaware has its own trade secret statute, the Delaware Uniform Trade Secrets Act (6 Del. C. 2001 and following sections), and the federal action in 18 U.S.C. 1836 sits alongside it.
- Which court? A case from Elsmere that belongs in federal court is filed in the District of Delaware, which holds court in Wilmington.
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.
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
Three years is the copyright limit in 17 U.S.C. 507(b), measured from when the claim accrued. Registration comes first under 17 U.S.C. 411(a), so the clock and the registration process can overlap.
Trade secret claims under federal law must be filed within three years of discovery, or of when reasonable diligence would have revealed the misappropriation, and continuing misappropriation is one 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.
Claims under Delaware 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.

Federal and Delaware Trademark Registration
The Lanham Act sets two routes to the principal register: use in commerce (15 U.S.C. 1051(a)(1)) and a bona fide intention to use (15 U.S.C. 1051(b)(1)). Each requires an application, a verified statement, and the prescribed fee.
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.
Copyright exists without a filing, but a lawsuit about a United States work requires preregistration or registration first (17 U.S.C. 411(a)). The standard term for a work created on or after January 1, 1978 is the life of the author and 70 years after the author’s death (17 U.S.C. 302(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.
Where an Intellectual Property Case From Elsmere Is Filed
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.
Delaware constitutes one federal judicial district, the District of Delaware (28 U.S.C. 87), so a federal case from Elsmere is filed there. The court holds court in Wilmington.
What Delaware 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 Delaware Uniform Trade Secrets Act (6 Del. C. 2001 and following sections). The state and federal claims are separate.
A state trademark registration in Delaware is a different filing from federal registration (15 U.S.C. 1051). It is made with the Delaware Secretary of State under Chapter 33 of Title 6 of the Delaware Code.
Whether to plead federal claims, state claims, or both turns on the facts, and an initial conversation with an attorney is the way to sort that out.
The Basics of Each Type of Claim
Patent Infringement
A patent claim asks whether the accused product or process is covered by the patent and whether the accused party acted without authority. The forms of infringement listed in 35 U.S.C. 271(a) are making, using, offering to sell, selling, and importing.
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 Infringement and Brand Disputes
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.
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)).
Keeping dated copies of drafts and finished work helps show what was created and when.
Protecting Confidential Business Information
The federal claim in 18 U.S.C. 1836(b)(1) is limited to trade secrets connected to interstate or foreign commerce, and the information must satisfy 18 U.S.C. 1839(3) to count as a trade secret at all.
A continuing misappropriation is treated as a single claim for the federal deadline (18 U.S.C. 1836(d)).
What a Court Can Award or Order
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.
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)).
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.
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.
In federal trade secret cases the court can enjoin actual or threatened misappropriation, award damages for loss and unjust enrichment or a reasonable royalty, and, for willful and malicious misappropriation, exemplary damages up to 2 times the damages awarded (18 U.S.C. 1836(b)(3)).

Documents and Dates That Help
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.
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
What can be patented?
A new and useful process, machine, manufacture, or composition of matter may be patented, subject to the conditions and requirements of the patent statute (35 U.S.C. 101).
Can I register a trademark before I start using it?
Yes, in one way: a person with a bona fide intention, under circumstances showing good faith, to use a trademark in commerce may request registration on the principal register (15 U.S.C. 1051(b)(1)).
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)).
How long do I have to bring a trade secret claim under federal law?
Three years after the misappropriation is discovered or, by the exercise of reasonable diligence, should have been discovered, and a continuing misappropriation counts as a single claim (18 U.S.C. 1836(d)).
Which court handles patent and copyright cases from Elsmere?
Both belong exclusively in federal district court (28 U.S.C. 1338(a)), which for Elsmere means the District of Delaware.
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.
Is there a deadline to sue for patent infringement?
Patent damages reach back six years before the complaint (35 U.S.C. 286), so delay can reduce recovery even while the patent is in force.
Can I protect a logo or slogan?
A word, name, symbol, or device used to identify and distinguish goods or services and indicate their source can be a trademark or service mark (15 U.S.C. 1127).
