Facing an IP infringement complaint? Don’t just react—respond with power. Learn how to strategically answer claims involving patents, trademarks, or copyrights and protect your creative, commercial, or technological edge.
When you're hit with an IP lawsuit, your answer is more than just a formality—it’s your chance to fight back. Whether you’re accused of infringing a patent, copying copyrighted content, or misusing a trademark, your response can dictate the tone, scope, and strategy of the entire case.
This guide unpacks how to draft a sharp, effective answer in IP litigation, from denial strategies to affirmative defenses and counterclaims.
An answer is your formal, legal response to an IP complaint. It gives you a structured platform to:
Deny or admit the plaintiff’s claims
Assert legal defenses (e.g., non-infringement or fair use)
File counterclaims (e.g., IP misuse, declaratory judgment of invalidity)
✅ Why It Matters: If you don’t answer within the required deadline—often 21 days in federal court—you could face a default judgment, meaning the court assumes you’ve conceded the claims.
📌 Case Information
Court name
Case number
Parties involved
Title: “Answer to Complaint for Patent/Trademark/Copyright Infringement”
📌 Admissions & Denials
Respond to each numbered paragraph in the complaint with:
Admit – Confirm the claim as true
Deny – Dispute the claim
Lack of Knowledge – Not enough info? State that, which counts as a denial
✅ Example:
"Defendant admits operating the mobile app referenced in Paragraph 3 but denies that its functionality infringes any of Plaintiff’s patent claims."
📌 Affirmative Defenses
These go beyond denial—they provide legal grounds for why the case should be dismissed:
Patent invalidity
Fair use (for copyright)
Functionality doctrine (for trademarks)
Statute of limitations
Lack of likelihood of confusion
📌 Counterclaims (Optional but Strategic)
Consider a countersuit if:
The plaintiff is violating your IP
You want the court to rule their IP is invalid
They’re abusing the legal system (e.g., patent trolling)
📌 Prayer for Relief
Clearly state what you want the court to do:
Dismiss the complaint
Declare the IP invalid
Award you legal fees or damages (if counterclaiming)
📌 Signature & Verification
Don’t forget to sign and date your answer, either personally or through your attorney.
🛡️ Non-Infringement
"Defendant’s product uses a completely different process and does not infringe on the patented method described."
🛡️ Invalidity
"The patent lacks novelty and is anticipated by prior art."
🛡️ Fair Use
"In accordance with 17 U.S.C. § 107, the copyrighted content was used for educational commentary and not for commercial gain."
🛡️ Laches
"Plaintiff delayed filing this suit for over 6 years despite full knowledge of Defendant’s use, and should now be barred from recovery."
🛡️ License or Consent
"Plaintiff granted Defendant a nonexclusive license to use the work in 2021, and the use was within the scope of that agreement."
✅ Best Practice: Use USPTO records, licensing contracts, and expert declarations to reinforce your defenses.
IN THE UNITED STATES DISTRICT COURT FOR THE [DISTRICT] DISTRICT OF [STATE] Case No.: [XXXX]
Plaintiff: [Company Name] Defendant: [Your Name or Company] ANSWER TO COMPLAINT FOR PATENT INFRINGEMENT
1. Defendant admits that it produces Product X but denies that the product infringes U.S. Patent No. 12,345,678. 2. Defendant denies that it had knowledge of the patent prior to the litigation. 3. Defendant lacks sufficient information to admit or deny the claims in Paragraph 7 and therefore denies them.
AFFIRMATIVE DEFENSES 1. Plaintiff’s patent is invalid due to obviousness and prior art. 2. The alleged infringing features were independently developed by Defendant. 3. Plaintiff’s claims are barred by the doctrine of laches.
COUNTERCLAIM Defendant requests a declaratory judgment that U.S. Patent No. 12,345,678 is invalid and unenforceable under 35 U.S.C. §§ 102 and 103.
PRAYER FOR RELIEF Defendant respectfully requests: - Dismissal of Plaintiff’s complaint with prejudice - Declaratory judgment of patent invalidity - Award of attorneys’ fees under 35 U.S.C. § 285 - Any other relief the Court deems just and proper
[Defendant’s Signature] [Attorney Info, if applicable] Date: [Insert Date]
⏳ Deadline: In federal court, answers are typically due within 21 days of service (unless extended by agreement or motion).
📂 Discovery Is Coming: Your answer will shape the scope of discovery. Tailor your denials and defenses with this next phase in mind.
🤝 Leverage for Settlement: A solid answer filled with valid defenses and counterclaims can push the plaintiff toward negotiation or dismissal.
✔ Be specific – Don’t generalize your denials. Precision matters.
✔ Be proactive – Raise all known defenses. You may waive them if not included early.
✔ Be strategic – Think ahead to trial, discovery, and potential motions.
✔ Be factual – Back up your position with documentation and expert opinion.
✔ Be represented – IP law is complex. An attorney can make all the difference.
In IP litigation, your answer is your first and best opportunity to push back. It's more than denying infringement—it's a tactical document that can challenge the plaintiff’s rights, assert your own, and set the tone for discovery and potential settlement.
