Immunogen’s US Patent 8,337,856, which claims antibody-toxin immunogates for the treatment of cancer, survives an IPR challenge in a final written decision by the PTAB. In an unpredictable art, the Board finds that general statements in the prior art giving hints of future research were insufficient to provide a reasonable expectation of success.
US Patent 7,885,887, claiming crowd funding, is invalid under §101. “The ‘887 Patent claims only the abstract and time-honored concept of patronage, and even the addition of an element of computer use is insufficient to render it valid under Section 101 of the Patent Act, 35 U.S.C. § 101.” Kickstarter’s motion for summary judgment is granted
Petitioner Apotex asserted that claims directed to fosaprepitant were obvious, but the PTAB finds that there was no valid lead compound, so the patent is not obvious.
EON’s patent with means-plus-function claiming describing complex computer functionality is indefinite because there are no algorithms to provide structure to the claims. When a patentee invokes means-plus-function claiming to recite a software function, it accedes to the reciprocal obligation of disclosing a sufficient algorithm as the corresponding structure.
In this Hatch-Waxman action, Apotex is attempting to trigger a forfeiture event, that if successful, will cause Mylan to forfeit its 180-day exclusivity for a generic copy of Benicar®, olmesartan medoximil, that Mylan is otherwise eligible to receive.
The court therefore found clear and convincing evidence that a person of ordinary skill at the time of the invention (in 2005) would have been motivated to use EDTA in the claimed amounts with a reasonable expectation of success.
in an obviousness analysis, an inherency argument has a heightened standard that must be the natural result flowing from the operation as disclosed in prior art references.
The panel concludes that looking to the earliest patent expiration for patents that are obvious variants “best fits and serves the purpose of the doctrine of double patenting.”
Prosecution laches is an equitable defense to a charge of patent infringement, that “may render a patent unenforceable when it has issued only after an unreasonable and unexplained delay in prosecution” that constitutes an egregious misuse of the statutory patent system.
Proof of obviousness based on structural similarity requires clear and convincing evidence that a medicinal chemist of ordinary skill would have been motivated to select and then to modify a prior art compound (e.g., a lead compound) to arrive at a claimed compound with a reasonable expectation that the new compound would have similar or improved properties compared with the old.
