Patenting New Uses For Old Inventions, Sean B. Seymore
Patenting New Uses For Old Inventions, Sean B. Seymore

A bedrock principle of patent law is that old inventions cannot be patented. And a new use for an old invention does not render the old invention patentable. This is because patent law requires novelty--an invention must be new. But while a new use for an old invention does not make the old invention patentable, the new use itself might be patentable. In fact, new-use patents comprise a significant part of the patent landscape-particularly in pharmaceuticals, when drug companies obtain new-use patents to repurpose old drugs. This trend has fueled debates over follow-on innovation and patent quality. But there is …

It is axiomatic that once an invention has been patented, it cannot be patented again. This aligns with the quid pro quo theory of patents — the public would receive nothing new in exchange for the second patent. Enforcing this rule is done through the novelty requirement, which bars a patent if the invention is already known. But the rule is hard to justify if the original patentee reneged on the quid pro quo by inadequately disclosing how to make and use the invention. The inadequate disclosure suggests that the original inventor did not invent anything and the public received …

The novelty requirement seeks to ensure that a patent will not issue if the public already possesses the invention. Although gauging possession is usually straightforward for simple inventions, it can be difficult for those in complex fields like biotechnology, chemistry, and pharmaceuticals. For example, if a drug company seeks to patent a promising molecule that was disclosed but never physically made in the prior art, the key possession question is whether a person having ordinary skill in the art (PHOSITA) could have made it at the time of the prior disclosure. Put differently, could the PHOSITA rely on then-existing knowledge …
