Drafting Crossclaims for Intellectual Property Cases
Intellectual property (IP) disputes are rarely simple. They often involve multiple parties, overlapping rights, and complex agreements. Whether it's a patent, trademark, copyright, or trade secret, crossclaims are an essential litigation tool when defendants need to shift liability or enforce legal obligations among co-defendants.
In this guide, we break down when and how to draft effective crossclaims in IP cases.
What Is a Crossclaim in IP Cases?
A crossclaim is a claim made by one defendant against another defendant in the same lawsuit. It allows a party to:
-
Shift liability for infringement
-
Assert ownership rights
-
Enforce contractual obligations such as licensing or indemnification
Example: A company sued for copyright infringement may crossclaim against a distributor who supplied the infringing content, alleging breach of their licensing agreement.
1. When to Use Crossclaims in IP Litigation
Shifting Liability for Infringement
Use a crossclaim when another party in the lawsuit contributed to or caused the alleged infringement.
-
Patent cases: Shift liability to a supplier or manufacturer
-
Trademark cases: Hold a co-defendant responsible for product packaging or branding errors
Challenging Ownership or Registration
Disputes over who owns a patent or trademark can lead to crossclaims to clarify rights or challenge validity.
-
Assert invalidity
-
Seek declaratory judgment on ownership
Enforcing Contractual Agreements
Crossclaims are valuable for enforcing IP licensing or indemnity clauses.
-
Failure to maintain IP rights
-
Breach of IP licensing terms
Addressing Third-Party Involvement
If another party contributed to the infringement (e.g., a subcontractor), file a crossclaim for contribution or indemnity.
2. Strategies for Drafting an IP Crossclaim
Clearly Identify the Legal Basis
-
State whether the claim involves breach of contract, indemnity, contribution, or direct infringement
-
Cite the relevant statute or agreement
Include Specific Factual Allegations
-
Timeline of events
-
Specific acts of the co-defendant
-
Documents supporting the claim (e.g., license agreements, communications)
Example: "Defendant B failed to label the product with the licensed trademark as required under Section 3 of the agreement."
Specify Requested Relief
-
Indemnification
-
Reimbursement of litigation costs
-
Declaratory relief
-
Injunctive relief against co-defendant actions
Check Jurisdiction and Venue
-
Confirm the court has jurisdiction over the crossclaim and the parties
3. Common Defenses to IP Crossclaims
-
Lack of Jurisdiction: Especially common when foreign suppliers or co-defendants are involved
-
Failure to State a Claim: Vague or unsupported crossclaims are easy targets for dismissal
-
Statute of Limitations: Ensure timely filing
-
Failure to Join Necessary Parties: Some claims may require inclusion of third parties not currently in the lawsuit
Final Tips for Effective Crossclaims in IP Disputes
-
Be Specific: Courts require more than vague assertions—lay out your evidence and legal theory clearly.
-
Think Strategically: Use crossclaims to gain leverage in settlement or reduce liability exposure.
-
Document Everything: Contracts, product specs, and communications are key.
-
Align with Defense Strategy: Crossclaims should complement your main defense, not distract from it.
