**Re: Demand Letter Regarding CIRRUS NORTHSTAR ARRAY Mark**

Dear Counsel:

We represent Cirrus Array Systems (Cirrus) in response to your recent demand letter. This communication is without prejudice and preserves all of Cirrus’s rights, claims, and defenses. Nothing herein constitutes an admission regarding the validity of Northstar Arc’s registration, priority beyond the public record, infringement, liability, or damages.

Cirrus categorically denies any claim of trademark infringement. Based on a holistic assessment of the applicable confusion factors, there is no likelihood of consumer confusion between our composite mark, **CIRRUS NORTHSTAR ARRAY**, and your mark, **NORTHSTAR ARC**.

First, regarding similarity, marks are compared as encountered in the marketplace. In our branding, “CIRRUS” appears first and largest, dominating the commercial impression. The addition of “ARRAY” further distinguishes our offering from your “ARC.” While both marks contain a shared term, extensive third-party use narrows the strength of that element. A commercial search identified 46 active energy or engineering businesses using “Northstar” in trade names within our sector, suggesting the term is not exclusively indicative of your source.

Second, the goods and channels differ materially. Northstar Arc provides grid-forecasting analytics, whereas Cirrus sells field-monitoring hardware and software for solar farms. While we share some enterprise customers, the products serve distinct technical functions in the energy supply chain. Furthermore, purchaser care is exceptionally high in this market. Our average contract value is $180,000, involving a four-to-six-month sales process requiring technical demonstrations, security reviews, and executive approval. Such sophisticated procurement dynamics significantly reduce the probability of confusion.

Regarding actual confusion, you cite a single vendor inquiry asking if our booth belonged to your group. This isolated instance was corrected immediately upon clarification and resulted in no misdirected contracts, payments, or support requests. Momentary uncertainty, absent commercial impact, is not conclusive evidence of likelihood of confusion. Finally, Cirrus selected our naming independently based on industry constellation terminology, with no reference to Northstar Arc in our internal records.

Consequently, we cannot comply with your demands for immediate cessation, domain transfer, destruction of materials, disclosure of customer or revenue data, or payment of damages at this stage. Providing informal discovery and committing to permanent changes prior to any agreement on liability would be inappropriate and prejudicial.

However, in the interest of maintaining positive industry relations, Cirrus is willing to engage in a controlled discussion regarding presentation and market-separation measures. We propose a 30-day standstill during which our counsel will discuss the consistent display of the full **CIRRUS NORTHSTAR ARRAY** mark and distinct branding practices. This proposal is made without admitting any obligation or liability and does not preclude Cirrus from continuing operations if no agreement is reached by the end of the period.

Please treat this letter as a final response to your current demand. We invite you to discuss the proposed standstill within seven days. All other rights and remedies remain expressly reserved.

Sincerely,

Counsel for Cirrus Array Systems
