Provisional Patent Application on Someone Else's Idea
Dear Rich: A former co-worker developed a new business idea. I signed an NDA and we both worked on commercializing the idea and planned to form a startup. He lost interest. An attorney reviewed the now-expired NDA and said I was fine to pursue the idea on my own, that I was under no obligation by the NDA. Can I file a provisional patent on the business idea? I would like to protect the idea by fixing a date in case I decide to file a formal patent application within the year. Any thoughts?Our first thought is that since you mentioned that you've already hired an attorney, why not ask your attorney whether to file? The Dear Rich staff provides helpful information, but your attorney knows more details about your case and could provide specific, client-centric advice (and probably has malpractice insurance to boot). Our second thought is that there is no such thing as a "provisional patent" (a common misconception). There is only a provisional patent application (or PPA) -- a document that establishes an official U.S. patent application filing date. (Nolo offers a free guide to PPAs that you can download here.)
As for filing your PPA with the USPTO, the PPA must be filed in the name of the inventor (or a co-inventor). A co-inventor is someone who contributes at least one novel and non-obvious concept that makes the invention patentable. If you didn't add anything patentable to the concept -- no Eureka! moments -- the PPA must be filed in the name of your co-worker. As for preserving the date of invention, you don't need a PPA to do so. Many inventors preserve their dates via an inventor's notebook. The important thing to keep in mind is that if you publicize or commercialize the idea, a patent application would have to be filed within one year in order to preserve patent rights. One way to avoid potential hassles is to work out a joint-ownership agreement with your former co-worker that will provide you with the right to exploit the idea while compensating him.
