Your Portsmouth 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 Portsmouth. 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
- A patent case is a federal case. The district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents (28 U.S.C. 1338(a)), and infringement damages are limited to the 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)).
- 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)).
- Ohio has its own trade secret statute, the Uniform Trade Secrets Act (R.C. 1333.61 to 1333.69), and the federal action in 18 U.S.C. 1836 sits alongside it.
- Where is my case filed? Portsmouth is in the Southern District of Ohio, and that court holds court in Cincinnati, Dayton, Columbus, St. Clairsville, and Steubenville (28 U.S.C. 115).
Which Type of Protection Fits Your Situation
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.
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)).
Unlike a patent, a trade secret is kept private. The federal definition requires reasonable secrecy measures and independent economic value from not being generally known or readily ascertainable through proper means (18 U.S.C. 1839(3)).
How Long Do You Have to Bring a Claim?
The copyright deadline is three years after the claim accrued (17 U.S.C. 507(b)). An owner who has not registered should treat registration as part of the first steps, since no infringement action on a United States work can be instituted before it (17 U.S.C. 411(a)).
Discovery drives the trade secret clock. A civil action under 18 U.S.C. 1836(b) may not be commenced later than three years after the misappropriation is, or by reasonable diligence should be, discovered (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).
The federal deadlines above do not decide state-law claims. Ohio 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
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)).
State registration is a different filing from a federal application. In Ohio it is made with the Ohio Secretary of State under R.C. 1329.54 to 1329.67, and an attorney can tell you whether a state filing, a federal filing, or both suit your plans.
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.
Federal and State Courts for Intellectual Property Claims
Patent, plant variety protection, and copyright claims belong exclusively in federal court: the district courts have original jurisdiction of any civil action arising under an Act of Congress relating to patents, plant variety protection, copyrights, and trademarks, and no state court may hear the patent, plant variety protection, and copyright claims (28 U.S.C. 1338(a)). Trademark claims may also be brought in state court.
The Southern District of Ohio covers Scioto County under 28 U.S.C. 115, and its places of holding court are Cincinnati, Dayton, Columbus, St. Clairsville, and Steubenville.
State-Law Rules for Trademarks and Trade Secrets
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 (R.C. 1333.61 to 1333.69). The state and federal claims are separate.
Beyond the federal Lanham Act, a brand owner in Portsmouth can look to Ohio’s own trademark registration system. Filings are made with the Ohio Secretary of State under R.C. 1329.54 to 1329.67, and a state filing does not replace a federal application.
Which claims to bring, and in which court, is a strategy question for an attorney who can read the documents.
Types of 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.
Both patent owners and people accused of infringing should collect the patent number, product samples, and dates early.
Trademark and Unfair Competition Claims
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.
A person who believes he or she is or is likely to be damaged can bring the civil action under 15 U.S.C. 1125(a)(1).
Protecting Creative Work
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)).
A civil action must be commenced within three years after the claim accrued (17 U.S.C. 507(b)).
Confidential Information and Departing Employees
A federal trade secret claim requires a trade secret related to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)), and the information must meet the definition of a trade secret in 18 U.S.C. 1839(3): reasonable secrecy measures and independent economic value.
Federal district courts have original jurisdiction over these actions (18 U.S.C. 1836(c)).
Injunctions and Money Damages by Type of Claim
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.
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.
Under 17 U.S.C. 504, the choice is between actual damages with additional profits and statutory damages, which the court sets between $750 and $30,000 for any one work.
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).
For a misappropriated trade secret, 18 U.S.C. 1836(b)(3) authorizes an injunction against actual or threatened misappropriation, damages for actual loss and unjust enrichment or a reasonable royalty, exemplary damages up to 2 times for willful and malicious misappropriation, and reasonable attorney’s fees to the prevailing party in stated situations.

Getting Your Records in Order
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.
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.
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 Portsmouth, that is the Southern District of Ohio.
What is the difference between federal and Ohio trademark registration?
Federal registration is on the principal register through the Patent and Trademark Office (15 U.S.C. 1051). Ohio registration is a separate filing made with the Ohio Secretary of State under R.C. 1329.54 to 1329.67, and it does not replace the federal one.
How long does a copyright last?
For a work created on or after January 1, 1978, the life of the author and 70 years after the author’s death (17 U.S.C. 302(a)), with different rules for joint works, anonymous and pseudonymous works, and works made for hire.
Does Ohio have a trade secret statute?
Yes. It is the Uniform Trade Secrets Act (R.C. 1333.61 to 1333.69). 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.
Which federal court covers Portsmouth?
The Southern District of Ohio (28 U.S.C. 115).
Can I bring both federal and Ohio claims?
Often yes. A dispute can involve federal claims, such as under 15 U.S.C. 1114 or 18 U.S.C. 1836, and state-law claims under Ohio law. An attorney can advise which to bring.
Why does timing matter in an intellectual property dispute?
Because federal statutes set fixed limits, such as three years for copyright (17 U.S.C. 507(b)) and for federal trade secret claims (18 U.S.C. 1836(d)), and six years of look-back for patent damages (35 U.S.C. 286), waiting can cost rights and money.
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)).
