Of the three major ex post patent validity challenge mechanisms that the 2011 Leahy-Smith America Invents Act put into place, the third is beginning to show signs of use. Post-grant review is an administrative proceeding of remarkable breadth as compared both to inter partes review and to the...

Patent Office power has grown immensely in this decade, and the agency is wielding its power in predictably troubling ways. Like other agencies, it injects politics into its decisions while relying on technocratic justifications. It also reads grants of authority expansively to aggrandize its...

Administrative patent revocation in the U.S. is poised to enter a new period of efficiency, though ironically it will be an efficiency that the America Invents Act originally put in place. The Court’s recent approval of the constitutionality of Patent Trial and Appeal Board ("PTAB")...

Scholars have spilled much ink questioning patent quality. Complaints encompass concern about incoming applications, examination by the U.S. Patent and Trademark Office (“USPTO”), and the USPTO’s ultimate output. The literature and some empirical data also suggest, however, that...

In recent years, the United States Patent and Trademark Office has systematically been engaging the legal community with inventor assistance beyond the agency's usual business of examining applications for patents and trademarks. The purpose of the USPTO's effort has been to support innovators...

Deciding a patent's validity is costly, and so is deciding it incorrectly. Judges and juries must expend significant resources in order to reach a patent validity determination that is properly informed by the relevant facts. At the same time, patent validity determinations reached quickly and...

Federal courts can ill afford to ignore, assume, or improvise a pervasively important administrative power that the Patent Office exercises regularly and effectively: technology classification. This agency-court asymmetry has persisted for decades but has now become unmanageably problematic for...

The progression toward reevaluating patent validity in the administrative, rather than judicial, setting became overtly substitutionary in the America Invents Act. No longer content to encourage court litigants to rely on Patent Office expertise for faster, cheaper, and more accurate validity...

This Article presents the first in a series of studies of stock market reactions to the legal outcomes of patent cases. From a sample of patents litigated during a 20-year period, we estimate market reactions to patent litigation decisions and to patent grants. These estimates reveal that the...
