Your Amherst Intellectual Property Attorney
If you are trying to protect an invention, a brand, or a creative work in Amherst, 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. This page covers the deadlines, the definitions that decide whether something is protected, the federal district court for Hillsborough County, and the New Hampshire rules that sit next to the federal ones. An attorney who handles intellectual property matters can tell you which of these rules apply to your situation.
Quick Answers on Patents, Trademarks, Copyrights, and Trade Secrets
- 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).
- 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)).
- 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)).
- 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)).
- The federal court for Amherst is the District of New Hampshire, with court held at Concord and Littleton (28 U.S.C. 109).
The Four Main Areas of Intellectual Property Law
A patent protects an invention. Whoever invents or discovers a new and useful process, machine, manufacture, or composition of matter may obtain a patent, subject to the conditions and requirements of the patent statute (35 U.S.C. 101). The term is 20 years from the date the application was filed (35 U.S.C. 154(a)(2)).
Under 15 U.S.C. 1127, a trademark is any word, name, symbol, or device, or a combination, that identifies and distinguishes one person’s goods from another’s and indicates their source, and a service mark performs that function 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)).
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)).
Time Limits That Matter in Patent, Copyright, and Trade Secret Cases
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 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)).
Six years is the number to know in patent cases: infringement more than six years before the complaint cannot be recovered on (35 U.S.C. 286).
A New Hampshire state-law claim brings its own deadline and its own accrual rule. Both come from New Hampshire statutes and court decisions and should be reviewed by an attorney at the start of the matter.

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)).
A New Hampshire business can ask an attorney whether a state-level trademark filing with the New Hampshire Secretary of State is worth adding to a federal application. The provisions are in the Model State Trademark Act, RSA chapter 350-A, and the two registrations are separate.
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.
Federal and State Courts for Intellectual Property Claims
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.
New Hampshire constitutes one federal judicial district, the District of New Hampshire (28 U.S.C. 109), so a federal case from Amherst is filed there. The court holds court in Concord and Littleton.
New Hampshire Law Alongside Federal Law
Owners of confidential information in Amherst 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)).
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.
Common Intellectual Property Claims
Patent Infringement
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).
Trademark and Unfair Competition Claims
For a registered mark, the core question is whether the defendant’s use of a reproduction, copy, counterfeit, or colorable imitation is likely to cause confusion, mistake, or deception in connection with goods or services (15 U.S.C. 1114(1)(a)).
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
Disputes Over Writing, Images, Music, and Film
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)).
For a United States work, registration must be made before an infringement suit is instituted (17 U.S.C. 411(a)).
Protecting Confidential Business Information
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)).
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
Damages, Injunctions, and Other Relief
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)).
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)).
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.
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)).

Documents and Dates That Help
Write down a short timeline before the call: when the work or invention was made, when it was first shown to anyone, and when you learned of the problem. The federal deadlines above are measured from dates like these.
For a patent question, bring drawings, notes, prototypes, any patent or application numbers, and information about who has seen or used the invention. For a trademark, bring the name or logo, examples of how it is used, and any registration papers.
For a copyright question, bring the work, dated drafts, any registration papers, and examples of the copying. For a trade secret question, bring a description of the information, who had access, and what confidentiality steps were in place, such as agreements and access controls.

The federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)). For Amherst, that is the District of New Hampshire.
What do I have to show to protect a trade secret?

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.
What should I do if someone copies my work?
Note the dates, keep copies, and speak with an attorney early, since deadlines such as three years for copyright (17 U.S.C. 507(b)) and six years of look-back for patent damages (35 U.S.C. 286) run from the events.
