Introduction
A competitor’s product may resemble yours without necessarily infringing a patent. Conversely, an implementation that looks different may still raise questions under the claims. Enforcement decisions should begin with the patent record, the accused activity and a clear business objective—not a demand letter drafted from visual similarity alone.
Key Takeaways
- Compare the accused product or process with the relevant claims.
- Check ownership, patent status and potential validity issues.
- A demand letter can have legal and commercial consequences.
Build a reliable record
Identify the patent and relevant claims, confirm who owns the rights, and check its status. Gather publicly available product materials and evidence of potentially relevant U.S. activity lawfully. Do not obtain evidence through unauthorized access.
Claim interpretation, prosecution history and the technical facts matter. Analysis may also need to consider validity, enforceability, licensing and applicable defenses.
Consider the response options
Potential paths include further investigation, licensing discussions, negotiated resolution or litigation. Costs, business relationships, available remedies and the strength of the evidence all affect the decision.
A cease-and-desist letter can provoke a response, including litigation by the recipient in appropriate circumstances. Avoid unsupported accusations or statements about damages without a legal assessment.
Practical Implications
Consult counsel before approaching the suspected infringer. Share the patent, relevant correspondence, product evidence and the outcome you hope to achieve.
If you receive a patent demand, preserve it and associated records, identify any stated deadlines and seek advice promptly. Do not assume the demand is valid, but do not ignore it.
Conclusion
Patent enforcement should begin with a lawful evidence record and a claim-focused legal assessment. Evaluate the risks and business objectives before selecting a response or approaching the other party.
