Catalyst patent would be a STUPID move for JBII. JBII prefers to keep it a trade secret.

"As with most industrial catalysts, its exact composition is a trade secret"

"How the manufacture gets from this recipe to the final product is often a trade secret"

"...in the presence of the appropriate catalyst. It's a hotly contested area, with most companies that make a new discovery choosing to keep the process as a trade secret, instead of discussing it in the open scientific literature."

So JBII is doing exactly what most others who own industrial catalysts do.
