How can an inference of suppression or concealment be rebutted?
An inference of suppression or concealment can be rebutted by showing renewed activity on the invention just prior to the junior party’s entry into the field, coupled with diligent filing of a patent application. The MPEP provides several examples of activities that may rebut this inference: Showing activity directed to perfecting the invention Preparing the…
Read MoreHow can an applicant rebut a prima facie case of anticipation or obviousness in product claims?
An applicant can rebut a prima facie case of anticipation or obviousness in product claims by providing evidence that demonstrates the prior art products do not necessarily possess the characteristics of the claimed product. This is explained in MPEP 2112.01(I): “Therefore, the prima facie case can be rebutted by evidence showing that the prior art…
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…
Read MoreHow does the “reasonably pertinent” test apply to analogous art determination?
The “reasonably pertinent” test is another important criterion for determining analogous art, especially when a reference is not from the same field of endeavor as the claimed invention. According to MPEP 2141.01(a): “A reference is reasonably pertinent if, even though it may be in a different field from that of the inventor’s endeavor, it is…
Read MoreWhat is the role of “reasonable interpretation” in making a prima facie case of equivalence?
What is the role of “reasonable interpretation” in making a prima facie case of equivalence? In making a prima facie case of equivalence, the examiner must use “reasonable interpretation” of the claim language. The MPEP states: “The examiner must apply to the questioned claim element reasonable interpretation of the claim language, including consideration of the…
Read MoreWhat is considered “reasonable experimentation” in patent applications?
“Reasonable experimentation” in patent applications refers to the amount of experimentation that would be considered acceptable and not “undue.” The MPEP provides guidance on this in section 2164.06: “‘The test is not merely quantitative, since a considerable amount of experimentation is permissible, if it is merely routine, or if the specification in question provides a…
Read MoreHow does the reasonable expectation of success requirement apply in unpredictable arts?
The reasonable expectation of success requirement applies to all fields of invention, but it can be more challenging to establish in unpredictable arts, such as biotechnology or pharmaceuticals. In these fields, the level of predictability is generally lower, which can affect the analysis of obviousness. The MPEP 2143.02 provides guidance on this issue, citing relevant…
Read MoreWhat role does “reasonable expectation of success” play in obviousness rejections?
What role does “reasonable expectation of success” play in obviousness rejections? The concept of “reasonable expectation of success” is a crucial element in determining obviousness in patent examination. According to MPEP 2143.02: “Obviousness does not require absolute predictability, however, at least some degree of predictability is required.” This means that when an examiner combines or…
Read MoreWhat is the role of “reasonable expectation of success” in obviousness determinations?
The “reasonable expectation of success” plays a crucial role in obviousness determinations under patent law. According to MPEP 2143.02, “Obviousness does not require absolute predictability, however, at least some degree of predictability is required.” This means that for an invention to be considered obvious, there must be a reasonable probability that the proposed modification or…
Read MoreWhat is the ‘reasonable expectation of success’ criterion in obviousness analysis?
What is the ‘reasonable expectation of success’ criterion in obviousness analysis? The ‘reasonable expectation of success’ is a crucial criterion in determining obviousness in patent examination. According to MPEP 2143, this concept is particularly important when considering whether a claimed invention would have been obvious to try. The MPEP states: “Obviousness can be established by…
