How does the USPTO handle prior art rejections when operability is questioned?
The USPTO handles prior art rejections where operability is questioned as follows: The examiner must provide a reasonable basis to question the operability of the prior art. If operability is questioned, the burden shifts to the applicant to provide rebuttal evidence. The prior art is presumed to be operable unless proven otherwise. As stated in…
Read MoreWhat is the significance of “efficacy” in determining prior art operability for patent examinations?
In patent examinations, the “efficacy” of a prior art reference is not a determining factor for its operability. As stated in MPEP 2121.02: “A prior art reference provides an enabling disclosure and thus anticipates a claimed invention if the reference describes the claimed invention in sufficient detail to enable a person of ordinary skill in…
Read MoreHow can an applicant rebut the presumption of operability in prior art?
An applicant can rebut the presumption of operability in prior art by providing evidence that shows a process for making the compound was not known at the relevant time. The MPEP 2121.02 states: “A reference is presumed operable until applicant provides facts rebutting the presumption of operability.” To overcome this presumption, an applicant must present…

What is the difference between operability and enablement in patent law? In patent law, operability and enablement are related but distinct concepts. According to MPEP 2121: Operability refers to whether an invention actually works as described. A reference is considered operable if the disclosed invention functions as claimed. Enablement, on the other hand, relates to…

Can a patent be invalidated if the biological deposit becomes non-viable? While the MPEP does not explicitly state that a patent will be invalidated if a biological deposit becomes non-viable, it does emphasize the importance of maintaining viability. MPEP 2409 states: “Failure to maintain a deposit in a viable and uncontaminated condition may result in…
Read MoreDoes an author’s failure to synthesize a compound invalidate it as prior art?
An author’s failure to synthesize a compound does not automatically invalidate it as prior art. The MPEP 2121.02 clarifies: “The fact that an author of a publication did not attempt to make the compound disclosed, without more, will not overcome a rejection based on that publication.” This means that simply because the author of a…
