Your Southfield Intellectual Property Attorney
Ideas, brands, and creative work are only as protected as the steps taken to secure them and the speed of the response when someone copies them. If your business or work is based in Southfield, the federal and Michigan rules on patents, trademarks, copyrights, and trade secrets are written down, and knowing them early helps. The sections that follow cover what patents, trademarks, copyrights, and trade secrets protect, the filing deadlines, registration, the federal courts for Oakland County, Michigan’s own trademark and trade secret rules, and what an infringement claim involves. Talking with an attorney who works in the Eastern District of Michigan can turn these general rules into a plan for your matter.
Intellectual Property Rules at a Glance
- 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)).
- 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)).
- Federal district: for Oakland County, the Eastern District of Michigan under 28 U.S.C. 102, holding court in Ann Arbor, Detroit, Flint, Port Huron, and Bay City.
Four Kinds of Intellectual Property and What Each Covers
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)).
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)).
Why Timing Matters in Intellectual Property Disputes
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 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)).
A patent owner who waits loses damages: under 35 U.S.C. 286, no recovery may be had for infringement committed more than six years before the complaint. The patent itself lasts 20 years from filing (35 U.S.C. 154(a)(2)).
State-law claims, such as a claim under the Uniform Trade Secrets Act (MCL 445.1901 to 445.1910) or a state trademark claim, have their own rules on limitation periods and on when a claim begins to run. Those are set by Michigan statutes and court decisions, so the dates should be checked by an attorney rather than assumed from the federal deadlines.

Registration Steps for Trademarks and Copyrights
For a trademark, the owner of a mark used in commerce may request registration on the principal register by paying the prescribed fee and filing an application and a verified statement with the Patent and Trademark Office (15 U.S.C. 1051(a)(1)). A person with a bona fide intention to use a mark in commerce may also apply (15 U.S.C. 1051(b)(1)).
Michigan also has its own trademark registration. A state filing is made with the Michigan Department of Licensing and Regulatory Affairs under Act 242 of 1969 (MCL 429.31 and following sections), is separate from the federal register, and does not replace a federal application.
Registering a copyright before there is a dispute avoids a delay later. The statute says no civil action for infringement of the copyright in a United States work may be instituted until preregistration or registration has been made (17 U.S.C. 411(a)).
The application date controls the length of patent protection, which ends 20 years after filing (35 U.S.C. 154(a)(2)), so planning the filing is part of protecting the invention.
Which Court Handles a Claim From Southfield
In practice, patent and copyright disputes are filed in federal district court (28 U.S.C. 1338(a)), federal trade secret claims start there as well (18 U.S.C. 1836(c)), and a trademark dispute can be filed in federal or state court.
The Eastern District of Michigan covers Oakland County under 28 U.S.C. 102, and its places of holding court are Ann Arbor, Detroit, Flint, Port Huron, and Bay City.
Trade Secrets and Trademarks Under Michigan Law
Owners of confidential information in Southfield can look to two sources: the Uniform Trade Secrets Act (MCL 445.1901 to 445.1910) 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)).
Trademark protection has a state layer as well. A state trademark registration in Michigan is filed with the Michigan Department of Licensing and Regulatory Affairs under Act 242 of 1969 (MCL 429.31 and following sections), and it is separate from federal registration on the principal register (15 U.S.C. 1051).
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 Claims and Defenses
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.
A patent case is filed in federal district court (28 U.S.C. 1338(a)).
Trademark Infringement and Brand Disputes
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.
Evidence such as first-use dates, sales records, and examples of actual confusion is easiest to gather before a dispute escalates.
Copyright Claims
Whether copying is actionable begins with what is protected. Copyright subsists in original works fixed in a tangible medium (17 U.S.C. 102(a)) and does not reach ideas, procedures, processes, systems, or methods of operation (17 U.S.C. 102(b)).
The duration of a copyright for a work created on or after January 1, 1978 is generally the life of the author plus 70 years (17 U.S.C. 302(a)).
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.
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)).
Damages, Injunctions, and Other Relief
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.
A brand owner who establishes a violation may recover the defendant’s profits, damages sustained, and costs (15 U.S.C. 1117(a)), and can ask the court for an injunction to stop the violation (15 U.S.C. 1116(a)), both subject to the principles of equity.
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)).
The registration date can decide whether statutory damages and attorney’s fees are available at all. Section 412 of the copyright statute bars them for infringement commenced before registration, subject to a three-month window after first publication.
In federal trade secret cases the court can enjoin actual or threatened misappropriation, award damages for loss and unjust enrichment or a reasonable royalty, and, for willful and malicious misappropriation, exemplary damages up to 2 times the damages awarded (18 U.S.C. 1836(b)(3)).

Documents and Dates That Help
Start with the basics: what you created or invented, who was involved, and when each step happened. Dates matter because the deadlines described above run from events such as accrual of a claim, discovery of a misappropriation, or the filing of an application.
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 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)).
Which court hears a copyright case from Southfield?
The federal district courts have original jurisdiction over copyright claims (28 U.S.C. 1338(a)). For Southfield, that is the Eastern District of Michigan.
What if a former employee took confidential information?
That can be a trade secret claim if the information meets the definition in 18 U.S.C. 1839(3), and the federal deadline is three years from discovery (18 U.S.C. 1836(d)). An attorney can review what was taken and what protections were in place.
Are trade secret cases filed in federal court?
A federal trade secret action under 18 U.S.C. 1836 is filed in federal district court (18 U.S.C. 1836(c)), and Michigan state-law claims are separate claims.
Can a trademark claim be brought under Michigan law?
Possibly. Michigan law may provide trademark claims of its own alongside the federal ones, and which apply depends on the mark and the facts. An attorney can explain the options.
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.
