Your South Portland Intellectual Property Attorney
Intellectual property law splits into four main areas, patents, trademarks, copyrights, and trade secrets, and each has its own rules on where a case is filed and how long you have. The sections below explain those rules for a matter arising in South Portland. 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. An attorney who handles intellectual property matters can tell you which of these rules apply to your situation.
Intellectual Property Rules at a Glance
- 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).
- Federal trademark registration is available to the owner of a mark used in commerce or to a person with a bona fide intention to use one (15 U.S.C. 1051(a)(1), (b)(1)).
- Register first, sue second. No civil action for infringement of the copyright in a United States work can be instituted until registration has been made or refused in the way the statute provides (17 U.S.C. 411(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)).
- A federal case from South Portland goes to the District of Maine (28 U.S.C. 99), which sits in Bangor and Portland.
What Patents, Trademarks, Copyrights, and Trade Secrets Protect
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 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.
A copyright question begins with whether the work is an original work of authorship fixed in a tangible medium (17 U.S.C. 102(a)) and whether what was copied was expression rather than an idea, system, or method (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.
How Long Do You Have to Bring a Claim?
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)).
Patent infringement damages reach back at most six years before the complaint (35 U.S.C. 286), so a suspected infringement is worth reviewing promptly.
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.

Steps That Strengthen a Claim Before It Is Needed
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 Maine can file for a state trademark registration with the Maine Secretary of State (see 10 M.R.S. chapter 301-A). The state filing is a separate process from the federal application.
Owners of creative work should know that registration is a precondition to suing on a United States work (17 U.S.C. 411(a)), and that the duration for most later works is 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.
Which Court Handles a Claim From South Portland
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.
Maine constitutes one federal judicial district, the District of Maine (28 U.S.C. 99), so a federal case from South Portland is filed there. The court holds court in Bangor and Portland.
What Maine 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 Uniform Trade Secrets Act (10 M.R.S. 1541 to 1548). The state and federal claims are separate.
A state trademark registration in Maine is a different filing from federal registration (15 U.S.C. 1051). It is made with the Maine Secretary of State under 10 M.R.S. chapter 301-A.

The Claims Behind Most Intellectual Property Disputes
Patent Disputes
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.
A patent case is filed in federal district court (28 U.S.C. 1338(a)).
Disputes Over Names, Logos, and Brands
Infringement of a registered mark means using in commerce a reproduction, counterfeit, copy, or colorable imitation of the mark in connection with the sale, offering for sale, distribution, or advertising of goods or services where the use is likely to cause confusion, mistake, or deception (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.
Copyright Claims
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)).
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
Confidential Information and Departing Employees
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)).
What a Successful Claim Can Recover
The patent statute provides for damages adequate to compensate for the infringement, not less than a reasonable royalty (35 U.S.C. 284), and for injunctions to prevent the violation of a patent right (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.
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)).
Under 17 U.S.C. 412, an owner who registers after an infringement has started may lose access to statutory damages and attorney’s fees for that infringement, unless the work was published and registered within three months of first publication.
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
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.
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
How long does a patent last?
A patent lasts 20 years from the date the application was filed in the United States (35 U.S.C. 154(a)(2)), so the filing date, not the issue date, sets the end of the term.
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)).
Do I have to register a copyright before I sue?
For a United States work, yes. No civil action for infringement of the copyright may be instituted until preregistration or registration of the copyright claim has been made (17 U.S.C. 411(a)), with a provision for cases where registration was refused.
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 federal court covers South Portland?
The District of Maine (28 U.S.C. 99).
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.
How long do I have to bring a copyright claim?
Three years after the claim accrued (17 U.S.C. 507(b)), and registration must come before suit on a United States work (17 U.S.C. 411(a)).
How do I know whether I need a patent, trademark, copyright, or trade secret protection?
It depends on what you are protecting: an invention (35 U.S.C. 101), a name or logo that identifies goods or services (15 U.S.C. 1127), original creative work (17 U.S.C. 102(a)), or confidential information (18 U.S.C. 1839(3)).
