Cease and Desist Letters
Received a demand letter, or considering sending one of your own? Wondering whether a cease and desist letter is the right first move, or whether it exposes you to a declaratory judgment lawsuit in a forum you didn’t choose? Unsure whether Florida’s Patent Troll Prevention Act applies to a patent demand you’ve drafted, or received?
Our patent, trademark, and copyright attorneys prepare and evaluate cease and desist and demand letters for inventors, entrepreneurs, and Florida businesses — built on independent pre-filing investigation, not boilerplate.
Pre-Filing Investigation Comes Before the Letter, Not After It
Why we verify the claim before we make it
A cease and desist letter goes out on firm letterhead, states facts as facts, and asserts a legal right as though it has already been tested. If any part of that is wrong — the wrong party, an expired or unenforceable right, a mischaracterized product, a use that turns out to be non-infringing — the sender has made an accusation it cannot back up, and the recipient now has a record of it. That record can surface later as evidence of bad faith, as the basis for an unfair-competition or tortious-interference counterclaim under statutes like Florida’s Deceptive and Unfair Trade Practices Act, or, in patent matters, as a statutory violation with fee-shifting and punitive exposure attached.
So before a letter leaves our office, we build the file: confirming the client’s ownership, registration, and priority date; comparing the accused product, mark, or work side by side against the right being asserted, item by item; and preserving evidence — listings, packaging, source code, metadata, purchase records — in a form that will still hold up if the matter is litigated a year from now.
Where third-party investigators come in
Some facts can’t be confirmed from a desk. We engage outside specialists where independent verification changes the strength — or the wisdom — of the claim:
- Licensed private investigators for test purchases and source verification, particularly for marketplace listings, unverified third-party sellers, or suspected counterfeit supply chains.
- Digital forensics specialists to capture and authenticate web pages, social posts, and online listings with a defensible chain of custody, before content can be edited, deleted, or moved.
- Patent and trademark search firms to confirm the current status, scope, and chain of title of the right being asserted — a right that has lapsed, been assigned, or narrowed on reexamination cannot support a letter written as if it were intact.
- Technical and survey consultants where the claim turns on functional similarity or a likelihood of consumer confusion rather than a side-by-side visual match.
This is the same standard of reasonable pre-filing inquiry that governs a filed pleading — because many demand letters end up as an exhibit to one. Doing that work up front is what lets a letter say, credibly, that the claim has already been tested.
Florida Statute § 501.993: Obligations Before Alleging Patent Infringement
The Patent Troll Prevention Act’s requirements for a demand letter
Florida’s Patent Troll Prevention Act, Fla. Stat. §§ 501.991–.997, applies specifically to demand letters that assert patent infringement against a Florida target. It doesn’t directly govern trademark, copyright, or trade-secret cease-and-desist correspondence — but its structure is a useful baseline for every letter our attorneys send: be specific, and be able to show your work.
Fla. Stat. § 501.993 — What a Compliant Patent Demand Letter Must Show
A letter alleging patent infringement can be treated as a bad-faith assertion if it lacks, or if the sender cannot substantiate:
- The identity of the party asserting the claim, including name and address.
- The specific patent alleged to be infringed, including the patent number.
- At least one product, service, or activity of the recipient identified with particularity as the accused conduct.
- Evidence that, before the letter was sent, the sender actually compared the patent’s claims against the recipient’s product or service and identified the specific areas of alleged coverage.
Courts may also weigh other indicators of bad faith: a demand for payment on an unreasonably short deadline, a licensing figure untethered to any reasonable royalty estimate, a refusal to provide substantiating information after the recipient requests it, or a pattern of sending similar letters that have previously been found meritless.
What’s at stake for the sender
The statute creates a private right of action — available to the recipient, the Florida Attorney General, and certain trade associations — for equitable relief, damages, and punitive damages of up to $75,000 against a party found to have repeatedly violated the Act. Certain senders and circumstances are exempted under Fla. Stat. § 501.997 (for example, original patent owners acting within specified conditions), and those exemptions are narrow and fact-dependent enough to warrant review before anyone assumes one applies.
Our practice: the claim-comparison analysis required by § 501.993 gets performed and documented before any patent-related letter leaves our office — whether or not the recipient technically meets the statute’s definition of a “target.” It is both the right way to make the accusation and the strongest available defense if the accusation is later challenged.
Cease and Desist Letter vs. Demand Letter
The two get used interchangeably. They’re asking for different things.
A cease and desist letter is, at its core, forward-looking — it asks the recipient to stop doing something. A demand letter is backward-looking — it asks the recipient to make the sender whole for something already done, usually by paying money. Many letters we send do both at once, and that blend is exactly why it matters to know which obligations attach to which half. If you’ve received one and aren’t sure which category it falls into, our attorneys also handle responses to demand letters.
| Cease and Desist Letter | Demand Letter | |
|---|---|---|
| Core ask | Stop the conduct — an injunction-style request | Pay, correct, or perform — a compensation-style request |
| Typical use | Trademark or copyright infringement, defamation, harassment, breach of a restrictive covenant | Contract debt, personal injury, unpaid royalties, patent licensing demands |
| What it documents | The right being infringed and the specific conduct to stop | The basis for liability and a calculation of what’s owed |
| If ignored | Suit for injunctive relief, often paired with damages | Suit for damages or collection |
| Governing checks | Underlying IP or tort rights, plus general pre-filing diligence | Same, plus statutory demand-letter rules where they apply — e.g., § 501.993 for patent demands |
Where a letter both demands that conduct stop and demands payment or a license fee, it inherits the risks of both categories at once — which is one more reason the framing gets decided deliberately, not by habit.
The Declaratory Judgment Risk
An overt threat of suit can hand the recipient the first move
A letter that goes beyond alleging infringement and threatens imminent litigation can do something the sender usually doesn’t want: it can give the recipient standing to sue first.
Why This Happens
A recipient who believes it is not infringing can go to court proactively and ask for a declaratory judgment that it has no liability — but only where there’s a real, immediate dispute between the parties, not a hypothetical one. Since the Supreme Court’s 2007 decision narrowing that threshold, a recipient no longer has to wait to be sued, or even stop the accused conduct, to bring that action; a sufficiently concrete threat in a letter can be enough on its own.
When that happens, the sender loses the two things a letter is usually meant to preserve: control over the timeline, and control over the forum. The recipient may file first, in a court of its own choosing — sometimes one considerably less convenient or favorable to the original claim.
The letters most likely to trigger this are the ones that read like a filed complaint: a specific date by which suit will be filed, a named court, or language asserting that infringement is ongoing and that litigation is the next and only step. Softer framing — an invitation to discuss, a request for a licensing conversation, a statement that litigation remains an option rather than a certainty — reduces that exposure, at some cost to the letter’s leverage.
Neither approach is categorically right. Our attorneys calibrate that choice deliberately: when preserving forum and timeline matters more than maximum pressure, the letter is written to say so; when urgency or forum indifference makes a threat-forward letter the better tool, that’s a deliberate call too — never a default.
How a Letter Gets Built, Start to Finish
Five steps between intake and service
- Rights confirmation. We verify ownership, registration status, priority date, and chain of title before treating any right as settled.
- Independent investigation. Desk review plus, where warranted, third-party investigators, forensic capture, or search-firm verification of the accused conduct.
- Statutory and procedural check. Confirming which pre-suit rules apply — § 501.993 for patent-related demands, and any other jurisdiction-specific requirements the claim triggers.
- Drafting and risk calibration. Choosing cease-and-desist or demand framing, and setting the letter’s tone and threat-level against the client’s actual tolerance for declaratory judgment exposure.
- Service, tracking, and escalation planning. The letter goes out with a plan already in place for what happens if it’s ignored, disputed, or answered with a lawsuit of the recipient’s own.
