John Behles, Patent Attorney
The firm is led by John Behles, a patent attorney with an engineering background and extensive experience in patent prosecution across multiple technology sectors. Over the course of his career, he has been involved in the prosecution of more than 1,000 patent applications spanning artificial intelligence, medical devices, cybersecurity, blockchain, autonomous systems, IoT, and traditional mechanical and electrical engineering.
His practice combines technical depth with business-oriented counsel. Before focusing on intellectual property, his experience included venture capital advisory, M&A due diligence, and startup formation work, providing the commercial perspective that informs how he approaches IP strategy. Patent filings are not treated as isolated legal events but as components of a broader business strategy tied to product development, competitive positioning, and exit planning.
The Practice
The firm's practice areas include patent prosecution across all technology sectors, IP portfolio strategy for companies from seed stage through acquisition, commercial law including technology contracts and IP licensing, startup law covering formation through venture financing, and trademark services including federal registration and brand protection. For medical device inventors, the firm operates a dedicated practice at MedicalPatents.com, coordinating patent prosecution with FDA regulatory timelines.
Technology Depth
The firm's technical experience spans artificial intelligence, cybersecurity, medical devices, blockchain and fintech, autonomous systems, and IoT and hardware. This breadth allows the firm to handle inventions that cross traditional technology boundaries, which increasingly describes the most valuable innovations being patented today.
