The Patent Trial and Appeal Board (PTAB) conducts trials, including inter partes, post-grant, and covered business method patent reviews and derivation proceedings; hears appeals from adverse examiner decisions in patent applications and reexamination proceedings; and renders decisions in interferences.
PTAB E2E will be unavailable for filing new petitions on Saturday, December 15, 2018 from 12:01-10 a.m. ET. Petitioners will need to pay for their petition outside of this scheduled maintenance time or make arrangements to pay early. Any other updates to already filed petitions are unaffected during this time. If your deadline is during this time for the petition filing or other associated documents to a pending AIA case, you must use an alternative filing method.
