What This Patent Covers

This patent protects a broad scope of claims (25 claims) covering the optical filter itself, its manufacturing method, and the optical module. It establishes a stable legal foundation, having overcome four prior art documents and benefiting from an accelerated examination, making it challenging for competitors to develop or circumvent with alternative technologies.

Competitive White Space

White space exists in developing advanced AI-driven image processing algorithms optimized for this filter's spectral characteristics, or in creating novel, self-cleaning protective coatings for the filter surface to further extend maintenance intervals.

estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming a company manufactures 100,000 outdoor optical modules annually, with a conventional product replacement cycle of 3 years and a replacement cost of $5.00/unit (AI est.). By extending the replacement cycle to 5 years with this technology, the annual number of replacements could decrease from approximately 33,000 units to 20,000 units. This could result in a direct cost reduction of (33,000 units - 20,000 units) × $5.00/unit = $65,000/year (AI est.). Including indirect labor costs for replacement work and opportunity losses, an annual cost reduction of over $150K (AI est.) is anticipated.
