Utility Patent Non-Infringement Letter

I need a licensed patent attorney to prepare a formal non-infringement opinion for my Amazon storefront. Amazon has flagged one of my listings and is asking for a letter—on official firm letterhead—affirming that my product does not infringe the cited U.S. utility patent. The focus is the patent’s underlying functionality rather than its design or branding.

Here is what I will provide right away:
• Full details of my product, including drawings, CAD files, and user instructions
• The patent number, claims, prosecution history, and any prior art already gathered
• A brief comparison chart I have started between my product’s functionality and each asserted claim

What I need from you:
• A clear, well-reasoned legal opinion letter addressed “To Whom It May Concern” that Amazon’s internal IP team will accept
• Citation to specific claim language and how my product avoids each element
• Your electronic signature and law-firm letterhead, plus a PDF I can upload without modification

Acceptance criteria:
1. Letter cites the exact patent number and claims at issue.
2. Provides claim-by-claim analysis demonstrating non-infringement of functionality.
3. Written in plain English with appropriate legal terminology, no more than three pages.
4. Delivered as a locked PDF within five business days of engagement.

If you have handled Amazon Seller Central non-infringement matters before, please mention a recent success (no confidential details needed). I’m available for a quick call to answer technical questions as soon as we start.
