Your Hanover Intellectual Property Attorney
If you are trying to protect an invention, a brand, or a creative work in Hanover, 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. You will find the quick answers first, then the definitions, deadlines, registration, the courts, state law, and the basic elements of infringement claims, with the statute behind each point. Talking with an attorney who works in the District of New Hampshire can turn these general rules into a plan for your matter.
Your Key Federal and New Hampshire Rules in One Place
- Patents belong in federal court. Federal district courts have original jurisdiction over patent claims (28 U.S.C. 1338(a)), and damages cannot reach back 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)).
- Three years to bring a copyright claim (17 U.S.C. 507(b)), and federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(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)).
- Where is my case filed? Hanover is in the District of New Hampshire, and that court holds court in Concord and Littleton (28 U.S.C. 109).
Patents, Trademarks, Copyrights, and Trade Secrets Compared
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)).
A brand is protected as a trademark when it functions to identify and distinguish goods from those of others and to indicate the source of the goods (15 U.S.C. 1127). The same statute defines a service mark for the source of 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)).
Trade secret protection depends on two things: the owner took reasonable measures to keep the information secret, and the information has independent economic value because it is not generally known or readily ascertainable (18 U.S.C. 1839(3)). Formulas, methods, processes, programs, and codes can all qualify.
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.
The federal trade secret deadline is set by 18 U.S.C. 1836(d): three years from the date the misappropriation was discovered or by the exercise of reasonable diligence should have been discovered, with continuing misappropriation counted as one claim.
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.
The federal deadlines above do not decide state-law claims. New Hampshire 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
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.
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.
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)).
For an invention, the patent term of 20 years runs from the date the application was filed (35 U.S.C. 154(a)(2)), so the timing of an application is worth discussing with a patent attorney.
The Federal Court for Grafton County
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.
Under 28 U.S.C. 109, New Hampshire is one federal judicial district, and Grafton County is part of it. The District of New Hampshire holds court in Concord and Littleton.
How New Hampshire 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 (RSA 350-B:1 to 350-B:9). The state and federal claims are separate.
A state trademark registration in New Hampshire is a different filing from federal registration (15 U.S.C. 1051). It is made with the New Hampshire Secretary of State under the Model State Trademark Act, RSA chapter 350-A.
The details of a state-law claim depend on the facts, and an attorney can explain which of the federal and state claims fit a particular dispute.
Types of Intellectual Property Claims
Using an Invention Without Permission
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.
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.
Disputes Over Names, Logos, and Brands
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.
Copyright Claims
In a copyright case, the first questions are whether the work is protected at all under 17 U.S.C. 102(a) and whether what was copied was protected expression rather than an idea or method excluded by 17 U.S.C. 102(b).
Keeping dated copies of drafts and finished work helps show what was created and when.
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)).
Documents showing who had access, and what confidentiality steps existed, are among the first things to preserve.
What a Successful Claim Can Recover
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).
The trademark remedies are set out in 15 U.S.C. 1116(a), which gives courts the power to grant injunctions, and 15 U.S.C. 1117(a), which lets a plaintiff recover defendant’s profits, damages, and costs once a violation is established.
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)).
Registering early matters for remedies as well as for suing: statutory damages and attorney’s fees are barred for infringement that began before registration, except when a published work is registered within three months after first publication (17 U.S.C. 412).
Relief under 18 U.S.C. 1836(b)(3) includes an injunction, compensatory damages or a reasonable royalty, exemplary damages of up to 2 times for willful and malicious misappropriation, and reasonable attorney’s fees to the prevailing party when the statute’s conditions are met.

Documents and Dates That Help
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.
Patent matters go faster with drawings, lab notes, patent or application numbers, and a list of who has seen the invention. Trademark matters go faster with the mark itself, samples of its use, and any registration documents.
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
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).
What is trademark infringement?
For a registered mark, it is using in commerce a reproduction, counterfeit, copy, or colorable imitation in connection with goods or services where the use is likely to cause confusion, mistake, or deception (15 U.S.C. 1114(1)(a)).
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 is a trade secret?
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)).
Where does the federal court for Hanover hold court?
The District of New Hampshire holds court in Concord and Littleton (28 U.S.C. 109).
Does state registration replace federal registration?
No. A state registration, where one is available, is a separate filing from federal registration on the principal register (15 U.S.C. 1051), and each operates on its own.
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 keep information as a trade secret?
Take reasonable measures to keep it secret, because that is one of the two elements of the definition (18 U.S.C. 1839(3)), and consult an attorney about what measures are reasonable for your business.
