Your Portland Intellectual Property Attorney
If you are trying to protect an invention, a brand, or a creative work in Portland, 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. 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 Cumberland County, and how Maine law fits alongside federal law. These rules apply across Maine, and an attorney familiar with the District of Maine can explain what to expect there.
Deadlines and Courts: The Short Version
- Patent claims are filed in federal court only (28 U.S.C. 1338(a)), and the six-year damages limit in 35 U.S.C. 286 makes early action important.
- 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 covers expression, not ideas: original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), but never an idea, procedure, process, system, or method of operation (17 U.S.C. 102(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 (18 U.S.C. 1839(3)).
- The federal court for Portland is the District of Maine, with court held at Bangor and Portland (28 U.S.C. 99).
The Four Main Areas of Intellectual Property Law
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)).
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.
Copyright protects expression, not ideas. The subject matter is original works of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and protection does not extend to any idea, procedure, process, system, or method of operation, however it is described (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.
Time Limits That Matter in Patent, Copyright, and Trade Secret Cases
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. Maine 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.

Registration Steps for Trademarks and Copyrights
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.
A Maine business can ask an attorney whether a state-level trademark filing with the Maine Secretary of State is worth adding to a federal application. The provisions are in 10 M.R.S. chapter 301-A, and the two registrations are separate.
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.
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.
Which Court Handles a Claim From Portland
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.
The federal court for Portland is the District of Maine, which covers all of Maine (28 U.S.C. 99) and holds court in Bangor and Portland.
How Maine Law Fits In
Maine has a trade secret statute of its own, the Uniform Trade Secrets Act (10 M.R.S. 1541 to 1548). A trade secret dispute from Portland can involve that statute, and the federal Defend Trade Secrets Act adds a civil action in federal court for a trade secret related to a product or service used in interstate or foreign commerce (18 U.S.C. 1836(b)(1), (c)).
Beyond the federal Lanham Act, a brand owner in Portland can look to Maine’s own trademark registration system. Filings are made with the Maine Secretary of State under 10 M.R.S. chapter 301-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.
The Claims Behind Most Intellectual Property Disputes
Patent Infringement
Whether conduct is infringement is measured against 35 U.S.C. 271(a), which reaches anyone who, without authority, makes, uses, offers to sell, or sells a patented invention in the United States or imports it during the patent’s term.
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 and Unfair Competition Claims
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.
State trademark registration in Maine is filed with the Maine Secretary of State under 10 M.R.S. chapter 301-A, separate from the federal statutes.
Disputes Over Writing, Images, Music, and Film
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)).
Federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)).
Confidential Information and Departing Employees
The Defend Trade Secrets Act lets the owner of a misappropriated trade secret sue when the secret relates to a product or service in interstate or foreign commerce (18 U.S.C. 1836(b)(1)). Whether the information qualifies depends on the definition in 18 U.S.C. 1839(3).
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
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.
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).
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)).

Getting Your Records in Order
An attorney will usually begin with dates: creation, first disclosure, first use in commerce, first publication, and discovery of the problem. Gathering them ahead of time saves a first meeting for the questions that matter.
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.
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 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)).
What kinds of work does copyright cover?
Original works of authorship fixed in any tangible medium of expression (17 U.S.C. 102(a)), including literary, musical, dramatic, and pictorial works, motion pictures, sound recordings, and architectural works.
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 Portland?
Both belong exclusively in federal district court (28 U.S.C. 1338(a)), which for Portland means the District of Maine.
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.
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 software or written material?
Written material and other original expression fixed in a tangible medium can be protected by copyright (17 U.S.C. 102(a)), but not the underlying ideas, procedures, or methods of operation (17 U.S.C. 102(b)).
