Sourcing from companies without these can lead to substandard performance or safety hazards.
- Inadequate Supply Chain Due Diligence: Some suppliers outsource components overseas without proper oversight, leading to inconsistent quality. It’s essential to audit not just the primary company but also its supply chain partners.
- Underestimating Operational Track Record: New startups may offer innovative technology but lack a proven history of long-term performance. Relying solely on prototypes or pilot projects without real-world data increases the risk of failure.
Failing to Conduct Thorough Intellectual Property (IP) Diligence
Clean energy innovation is heavily IP-driven, and sourcing from companies with weak or contested IP can expose buyers to legal and financial risks.
- Assuming IP Ownership is Clear: Many U.S. clean tech firms operate with complex IP arrangements, including university licenses, government-funded R&D, or joint development agreements. Failing to verify full ownership or usage rights can result in infringement claims or restricted deployment.
- Ignoring Freedom-to-Operate (FTO) Analysis: Even if a company owns its patents, its technology might infringe on third-party IP. A lack of FTO analysis increases the risk of litigation and can invalidate procurement decisions.
- Overlooking IP in Mergers and Acquisitions: When sourcing through partnerships or acquisitions, incomplete IP transfers or undisclosed liens on patents are common. Ensure all IP assets are properly assigned and documented.
- Underestimating Trade Secret Risks: Some companies rely on trade secrets rather than patents. Without strong contractual safeguards (e.g., NDAs, non-compete clauses), there’s a risk of misappropriation or loss of proprietary know-how.
Conclusion
To mitigate risks when sourcing clean energy companies in the USA, conduct comprehensive due diligence on both quality assurance processes and intellectual property frameworks. Engage technical experts to evaluate product certifications and performance data, and involve legal counsel to audit IP portfolios and licensing agreements. Proactive assessment in these areas ensures long-term reliability, compliance, and competitive advantage.
