Adisyn Strengthens US Patent Portfolio with Product-Focused Graphene Claims

Second US Patent Broadens Product Protection

Adisyn Ltd (ASX:AI1) has taken a significant step in fortifying its intellectual property by securing allowance of its second US patent application, which targets graphene-coated three-dimensional surfaces with unique physical properties relevant to next-generation semiconductor interconnects. Unlike its earlier May 2026 patent that focused on the method of applying graphene coatings, this new allowance protects the end-product itself, regardless of how it is manufactured.

The United States Patent and Trademark Office (USPTO) granted the allowance for Application No. 18/835,836, jointly held with research partner 2D Generation Ltd, covering graphene coatings characterised by features such as a median copper grain size under 0.9 microns, reduced shorts and voids after exposure to high temperatures, and coatings free from nitrogen doping and metal catalyst contaminants. Notably, the claims extend to interconnects without diffusion barrier coatings, potentially freeing space as semiconductor devices continue to shrink.

Protection Independent of Manufacturing Routes

The patent’s product-focused claims mean Adisyn’s protection applies even to graphene-coated surfaces produced by alternative methods that do not use its proprietary precursors or processes. This strategic breadth complements the company’s prior patent on its atomic layer deposition (ALD) technique, collectively creating a layered intellectual property framework that guards both the manufacturing technology and the specifications of the resulting products.

Adisyn’s Managing Director Arye Kohavi emphasised the relevance of these characteristics to semiconductor challenges, noting that factors like copper grain size and defect reduction influence electrical and thermal performance, while eliminating diffusion barriers could enable further device scaling. The company’s IP strategy also incorporates trade secrets and operational know-how, reinforcing its competitive position as it advances commercialisation.

Commercialisation and Industry Engagement

Adisyn is actively progressing its semiconductor interconnect program alongside its radar signature reduction technology for UAV and defence platforms. The company is engaging with potential partners and customers in both sectors and plans to expand its patent portfolio in other jurisdictions where appropriate.

This patent development follows recent announcements of repeatable low-temperature graphene deposition processes and strategic partnerships to accelerate graphene-enhanced stealth drone components, underscoring Adisyn’s momentum in translating its technology into commercial applications. The company’s broader business also includes managed IT and AI services for SMEs, though its core focus remains on advanced graphene materials.
