I think you may be mistaken on that Kalera. It is the expression of the idea that is copyrighted, not the idea itself.

What Works Are Protected?
Copyright protects “original works of authorship” that are
fixed in a tangible form of expression. The fixation need not
be directly perceptible so long as it may be communicated
with the aid of a machine or device.
What Is Not Protected by Copyright?
Several categories of material are generally not eligible for
federal copyright protection. These include among others:
• Works that have not been fixed in a tangible form of
expression (for example, choreographic works that have
not been notated or recorded, or improvisational speeches
or performances that have not been written or recorded)
