Background
Dane Butzer is the inventor of “key shadowing,” a quantum-resistant encryption technique that splits a cryptographic key into multiple fragments (shadows) dispersed across hyperdimensional coordinates. The key is never persistently stored—it exists only briefly at the moment it is needed, then is destroyed. This design aims to defeat both conventional attacks and the threat posed by future quantum computers that could break standard encryption schemes.
Butzer filed U.S. Patent No. 9,634,836 (“Key Shadowing”) and also registered associated software code as an unpublished copyrighted work (Reg. No. TXu 2-349-503). At some point, Butzer assigned the patent to the company that would become HyperSphere Technologies, Inc.—originally incorporated as Hyperspace Security, Inc.—which has built a cloud-first, API-driven cybersecurity platform around the key-shadowing concept.
In 2025, Butzer filed suit in the Northern District of Georgia against HyperSphere Technologies, its CEO James DeCesare, and a third individual, Todd Miller. Butzer alleged that the defendants were infringing his registered copyright in the software code underlying the key-shadowing technology. The complaint attached the patent assignment to HyperSphere as an exhibit, suggesting the dispute centered on whether the patent transfer had also carried the copyright in the associated source code—or whether Butzer had retained and was still the rightful owner of the software expression of his invention.
The Court’s Holding
Judge J.P. Boulee granted the defendants’ motion to dismiss the complaint in its entirety. The claims against Todd Miller were dismissed for lack of personal jurisdiction—he apparently lacked sufficient contacts with Georgia to be sued there. The claims against HyperSphere Technologies and James DeCesare were dismissed for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6), meaning Butzer’s complaint, even taken as true, did not contain enough factual allegations to support a plausible copyright infringement claim.
The court also denied the defendants’ separate motion for sanctions. Despite prevailing on the merits, HyperSphere and its co-defendants had argued the lawsuit was frivolous and sought attorney’s fees and other penalties against Butzer. Judge Boulee declined, indicating that the copyright claims, while legally insufficient as pled, did not reach the level of frivolousness required to warrant sanctions.
Key Takeaways
- Assigning a patent to a company does not automatically transfer the copyright in the software code that implements the patented invention—but a plaintiff must clearly plead that the copyright was retained and that the specific protectable expression was copied.
- Copyright infringement claims require more than identifying a registration number; the complaint must plausibly allege both ownership of valid copyright and copying of protected expression.
- Courts continue to deny sanctions even when copyright claims are dismissed at the pleading stage, as long as the claims reflect some colorable legal theory.
- Personal jurisdiction over individual officers and employees of a defendant company requires independent contacts with the forum state, not just their employer’s presence there.
Why It Matters
The case highlights a critical intellectual property planning gap that trips up many technical founders: when you assign a patent to your company, you should also explicitly address what happens to the copyright in the source code that embodies the invention. Patents and copyrights are separate rights—patents cover the functional idea, copyrights protect the expressive code—but they often cover the same underlying work. Without a clear written agreement, both the company and the original developer may have plausible but competing claims to the software.
For cybersecurity startups in particular, where the core product is often software-expressed patented technology, this case is a reminder to pair patent assignments with comprehensive IP agreements that address copyright ownership, work-for-hire status, and licensing. A clean IP transfer at incorporation can prevent disputes that, as here, may cost years of litigation even if ultimately dismissed.
