Patent FAQs*

Structura Biotechnology is a scientific software company that contributes to the field of cryo-electron microscopy (cryo-EM) by creating professionally designed and engineered software for academic and industrial use.

Why does Structura apply for patents?

Patents allow us to maintain competitive scientific research and development projects in the commercial space by protecting certain intellectual property, while providing certain scientific software and research tools free of charge for individual academic use.

What rights does a patent provide?

A patent is a time-limited legal right that can be applied for by an innovator in order to commercially protect a specific novel invention, in exchange for fully describing and disclosing the invention, how it works and why it is useful. If granted, a patent gives the owner the exclusive right to commercially make, use, distribute and sell the invention in a particular geographic area, subject to any licenses (permissions) the owner may give to third parties, usually for a period of up to 20 years from the filing date.

How do Structura’s patents affect scientists?

In short, our patents do not affect non-commercial scientific activity. We encourage and support free and open Non-profit Academic Research relating to our Patented intellectual property (IP) by granting the below license to eligible Licensees for perpetual, worldwide Non-profit Academic Research of the Patented IP.
