Your Derry 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 New Hampshire rules that most often decide how an intellectual property matter from Derry unfolds. Below you will find the key deadlines at a glance, what each type of protection covers, the steps that come before a lawsuit, which federal court hears a case from Rockingham County, and how New Hampshire law fits alongside federal law. Talking with an attorney who works in the District of New Hampshire can turn these general rules into a plan for your matter.
Deadlines and Courts: The Short Version
- Patent term and damages: a patent lasts 20 years from the filing date of the application (35 U.S.C. 154(a)(2)), and no recovery can be had for infringement more than 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)).
- 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)).
- 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)).
- Federal district: for Rockingham County, the District of New Hampshire under 28 U.S.C. 109, holding court in Concord and Littleton.
Four Kinds of Intellectual Property and What Each Covers
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.
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.
For creative work, copyright arises in original works of authorship fixed in a tangible medium of expression (17 U.S.C. 102(a)). The limit in 17 U.S.C. 102(b) means the underlying idea or method is not protected even when the way it is expressed is.
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.
Why Timing Matters in Intellectual Property Disputes
Under 17 U.S.C. 507(b), a civil copyright action must be commenced within three years after the claim accrued, and under 17 U.S.C. 411(a) the copyright claim for a United States work must be registered, or registration refused, before that action is instituted.
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)).
Do not assume that a state-law claim follows the federal deadlines. New Hampshire’s limitation periods and the point when a claim accrues are matters of New Hampshire statutes and case law, and an attorney can check the dates for your particular claim.

What to Do Before a Dispute Starts
Federal trademark registration is available both to owners of a mark already used in commerce (15 U.S.C. 1051(a)(1)) and to a person with a bona fide intention, in good faith, to use a mark in commerce (15 U.S.C. 1051(b)(1)), through an application and a verified statement filed with the Patent and Trademark Office.
Federal registration is not the only route. New Hampshire’s trademark registration provisions, the Model State Trademark Act, RSA chapter 350-A, provide for a state filing with the New Hampshire Secretary of State that operates separately from the federal register.
A copyright owner cannot file an infringement action on a United States work before registration has been made (17 U.S.C. 411(a)), although a refusal of registration can also open the door to suit if the Register of Copyrights is notified and served with the complaint.
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 Derry 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.
There is only one federal district in New Hampshire. The District of New Hampshire hears federal cases from Rockingham County and holds court in Concord and Littleton (28 U.S.C. 109).
How New Hampshire Law Fits In
Owners of confidential information in Derry can look to two sources: the Uniform Trade Secrets Act (RSA 350-B:1 to 350-B:9) 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)).
Beyond the federal Lanham Act, a brand owner in Derry can look to New Hampshire’s own trademark registration system. Filings are made with the New Hampshire Secretary of State under the Model State Trademark Act, RSA chapter 350-A, 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.
Common Intellectual Property Claims
Using an Invention Without Permission
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.
Because the six-year damages limit in 35 U.S.C. 286 runs back from the complaint, delay can reduce what is recoverable.
Disputes Over Names, Logos, and Brands
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.
Trademark claims may be filed in federal court or in state court (28 U.S.C. 1338(a)).
Copyright Infringement
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)).
Federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)).
Trade Secret Claims
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)).
Injunctions and Money Damages by Type of Claim
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).
For trademark violations, the Lanham Act allows injunctions on terms the court considers reasonable (15 U.S.C. 1116(a)) and allows recovery, subject to equity, of the defendant’s profits, the plaintiff’s damages, and the costs of the action (15 U.S.C. 1117(a)).
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)).
Registration timing affects these remedies: no award of statutory damages or attorney’s fees is available for infringement of an unpublished work commenced before the effective date of its registration, or for infringement commenced after first publication and before registration unless registration is made within three months after first publication (17 U.S.C. 412).
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 to Gather Before You Talk to an Attorney
Bring a simple chronology. When was the work created, when was it first shared or sold, and when did you first notice the copying or use? Many of the deadlines on this page run from those events.
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.
Copyright matters call for the original work, dated versions, registration papers, and side-by-side examples of the copying. Trade secret matters call for a description of the information, a list of who had access, and the confidentiality measures that existed.

Frequently Asked Questions
Where is a patent infringement case filed?
In federal district court. The district courts have original jurisdiction of civil actions arising under patent law, and that jurisdiction is exclusive (28 U.S.C. 1338(a)). For Derry, that is the District of New Hampshire.
Can I register my business name or logo as a trademark?
A word, name, symbol, or device used to identify and distinguish goods and indicate their source is a trademark (15 U.S.C. 1127), and the owner of a mark used in commerce may request federal registration (15 U.S.C. 1051(a)(1)).
Can I copyright an idea?
No. Copyright never extends to any idea, procedure, process, system, method of operation, concept, principle, or discovery (17 U.S.C. 102(b)). It protects the original expression of an idea.
Does New Hampshire have a trade secret statute?
Yes. It is the Uniform Trade Secrets Act (RSA 350-B:1 to 350-B:9). The federal Defend Trade Secrets Act provides a separate civil action (18 U.S.C. 1836), and an attorney can tell you which claims fit the facts.
How many federal districts does New Hampshire have?
New Hampshire has one federal judicial district: the District of New Hampshire (28 U.S.C. 109).
Does New Hampshire law protect trade secrets?
Yes. New Hampshire has the Uniform Trade Secrets Act (RSA 350-B:1 to 350-B:9), and the federal Defend Trade Secrets Act (18 U.S.C. 1836) adds a separate federal action.
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 business idea?
An idea by itself is not protected by copyright (17 U.S.C. 102(b)). An invention that fits a category in 35 U.S.C. 101 may be patentable, and confidential business information may qualify as a trade secret (18 U.S.C. 1839(3)).
