Your Warren Intellectual Property Attorney
A patent, a trademark, a copyright, and a trade secret are four different things with four different sets of rules. For a Warren business, artist, or inventor, the first step is knowing which one is actually involved, and this page walks through how to tell. 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 Macomb County, and how Michigan law fits alongside federal law. Deadlines in intellectual property cases run on fixed dates, so learning them early usually helps more than trying to catch up later.
Deadlines and Courts: The Short Version
- Who can be liable for patent infringement? Anyone who, without authority, makes, uses, offers to sell, or sells a patented invention in the United States, or imports it (35 U.S.C. 271(a)).
- 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)).
- How long does a copyright last? For works created on or after January 1, 1978, the life of the author plus 70 years (17 U.S.C. 302(a)), with different counts for joint works and works made for hire.
- 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)).
- The federal court for Warren is the Eastern District of Michigan, with court held at Ann Arbor, Detroit, Flint, Port Huron, and Bay City (28 U.S.C. 102).
Four Kinds of Intellectual Property and What Each Covers
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)).
If the issue is a business name, logo, or slogan, the question is trademark, which the Lanham Act defines as a word, name, symbol, or device that identifies and distinguishes goods and indicates their source (15 U.S.C. 1127), with service marks covering 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)).
If the valuable thing is confidential know-how, the question is trade secret. Both elements in 18 U.S.C. 1839(3) must be present: reasonable measures to keep the information secret, and independent economic value from its not being generally known.
Time Limits That Matter in Patent, Copyright, and Trade Secret Cases
For copyright infringement, the statute sets three years from when the claim accrued (17 U.S.C. 507(b)), and registration or a refusal of registration must come before suit on a United States work (17 U.S.C. 411(a)).
Trade secrets: a federal action under the Defend Trade Secrets Act may not be commenced later than 3 years after the misappropriation is discovered or, with reasonable diligence, should have been discovered, and a continuing misappropriation counts as a single 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).
The federal deadlines above do not decide state-law claims. Michigan 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
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)).
Federal registration is not the only route. Michigan’s trademark registration provisions, Act 242 of 1969 (MCL 429.31 and following sections), provide for a state filing with the Michigan Department of Licensing and Regulatory Affairs that operates separately from the federal register.
Copyright exists without a filing, but a lawsuit about a United States work requires preregistration or registration first (17 U.S.C. 411(a)). The standard term for a work created on or after January 1, 1978 is the life of the author and 70 years after the author’s death (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
The choice of court depends on the type of claim. Patent and copyright cases can only be filed in federal district court (28 U.S.C. 1338(a)), a federal trade secret action is filed in federal district court (18 U.S.C. 1836(c)), and trademark claims can go to federal or state court.
Under 28 U.S.C. 102, Michigan’s counties are grouped into two federal districts. For Macomb County, the court is the Eastern District of Michigan, and it holds court in Ann Arbor, Detroit, Flint, Port Huron, and Bay City.
What Michigan Law Can Add to Federal Protection
The federal civil action for trade secrets (18 U.S.C. 1836(b)(1)) is filed in federal district court (18 U.S.C. 1836(c)), and a dispute from Warren may also raise a claim under the Uniform Trade Secrets Act (MCL 445.1901 to 445.1910). Which claims fit depends on the facts.
Beyond the federal Lanham Act, a brand owner in Warren can look to Michigan’s own trademark registration system. Filings are made with the Michigan Department of Licensing and Regulatory Affairs under Act 242 of 1969 (MCL 429.31 and following sections), and a state filing does not replace a federal application.

What Kinds of Intellectual Property Cases Come Up?
Patent Infringement
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
Even without registration, the Lanham Act allows a civil action against anyone who uses in commerce a word, term, name, symbol, or device likely to cause confusion or deceive about affiliation, connection, or origin (15 U.S.C. 1125(a)(1)), brought by a person who believes he or she is or is likely to be damaged.
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).
Disputes Over Writing, Images, Music, and Film
A copyright claim starts with an original work of authorship fixed in a tangible medium (17 U.S.C. 102(a)), and it is limited to expression: the idea, procedure, process, system, or method of operation is not protected (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)).
Trade Secret Misappropriation
The federal claim in 18 U.S.C. 1836(b)(1) is limited to trade secrets connected to interstate or foreign commerce, and the information must satisfy 18 U.S.C. 1839(3) to count as a trade secret at all.
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.
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)).
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.
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.

Getting Your Records in Order
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.
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
How far back can I recover damages for patent infringement?
Six years before the complaint. No recovery may be had for infringement committed more than six years before the filing of the complaint (35 U.S.C. 286).
Can I register a trademark before I start using it?
Yes, in one way: a person with a bona fide intention, under circumstances showing good faith, to use a trademark in commerce may request registration on the principal register (15 U.S.C. 1051(b)(1)).
Can I copyright an idea?
No. Copyright never extends to any idea, procedure, process, system, method of operation, concept, principle, or discovery (17 U.S.C. 102(b)). It protects the original expression of an idea.
Can I sue in federal court over a stolen trade secret?
Yes, if the trade secret is related to a product or service used in, or intended for use in, interstate or foreign commerce (18 U.S.C. 1836(b)(1)). The federal district courts have original jurisdiction of these actions (18 U.S.C. 1836(c)).
Which federal court covers Warren?
The Eastern District of Michigan (28 U.S.C. 102).
Do federal deadlines apply to Michigan state-law claims?
Not automatically. Michigan state-law claims have their own limitation periods and accrual rules, set by Michigan statutes and court decisions, and an attorney should check them.
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.
