Read MoreWhen does experimental use end and potentially trigger a public use bar?
The transition from experimental use to a potential public use bar occurs when the inventor relinquishes control over the invention. The MPEP states: Once a period of experimental activity has ended and supervision and control has been relinquished by an inventor without any restraints on subsequent use of an invention, an unrestricted subsequent use of…
Read MoreHow does control and supervision affect experimental use in patent law?
Control and supervision by the inventor are crucial factors in determining whether an activity qualifies as experimental use. The MPEP emphasizes: “The significant determinative factors in questions of experimental purpose are the extent of supervision and control maintained by an inventor over an invention during an alleged period of experimentation, and the customer’s awareness of…
