Volt Carbon receives notice of allowance from USPTO

Executive Summary

• Volt Carbon Technologies received a USPTO notice of allowance for a second U.S. patent covering its air‑classifier technology, expanding the scope of protection for its graphite processing platform.
• The company successfully produced five‑layer reduced graphene oxide (rGO) sheets from its proprietary air‑classified graphite; incorporation into aerospace epoxy resin yielded a 40 %–60 % improvement in mechanical properties versus virgin epoxy.
• An aggregate of 6.5 million stock options were granted to officers, employees and contractors at an exercise price of C$0.05 per share, vesting immediately for a five‑year term.

Key Details

• Patent Allowance: USPTO issued notice of allowance for U.S. patent application No. 18/782,462 (continuation of Patent No. 12,172,192). The company must pay issue fees before the patent is granted and assigned a number.
• Scope Expansion: Continuation broadens protection of Volt Carbon’s proprietary air‑classifier technology used in graphite processing and advanced material applications.
• Graphene Production: Produced reduced graphene oxide (rGO) from Berkwood flake graphite processed via the company’s air classifier; created five‑layer rGO sheets up to ~16.5 µm wide, confirmed by TEM at University of Waterloo.
• Composite Testing: Integrated rGO sheets into standard aerospace epoxy resin; mechanical testing showed a 40 %–60 % increase in strength and stiffness compared with virgin epoxy, positioning the material for aerospace carbon‑fibre composite applications.
• Potential Market Impact: Results support pursuit of partnerships in aerospace composites and advanced materials markets, addressing brittleness and interlaminar cracking issues in current CFRPs.
• Stock Option Grant: 6.5 million options granted under the company’s stock option plan; each option exercisable for one common share at C$0.05 per share, five‑year term, immediate vesting, subject to TSX Venture Exchange approval.
