to know the line between a private and a public use. Subsequent legislation The 2011 America Invents Act (AIA) may have completely overturned Egbert v. Lipmann. The public use provision of the statute now provides that a person is not entitled to a patent if "the claimed invention was . . . in public use . . . or otherwise available to the public before the effective filing date of the claimed invention." That appears to limit public use to uses available to the public and to exclude as bars to patentability any hidden, inaccessible, private uses, since it implies that public use is within the class of things otherwise available to the public. A steel spring hidden within a corset would not seem to be available to the public. The availability requirement is consistent with the AIA's legislative history. Prior to the Senate vote, Senator Jon Kyl explained to the Senate that the Judiciary Committee had added the words "otherwise available to the public" to "abrogate...the rule announced in Egbert v. Lippmann." Commentary Feminist commentator Kara Swanson analyzed the case as explicating the public use doctrine at "the intersections of gender and intellectual property from a feminist perspective." In her view: Like the more celebrated technologies of the era, such as the telephone, the telegraph, and the light bulb, the corset was the product of many inventors, making and patenting improvements, and fighting about their rights in court. As American women donned their corsets, they were enacting a daily intimate relationship with a heavily patent-protected technology. The corset during these decades was deeply embedded both within the social construction of gender and sexuality, as a marker of femininity and respectability, and within the United States patent system, as a commercial good in which many claimed intellectual property rights. Getting a grip on the corset, then, offers a way to simultaneously consider gender, sexuality, and patent law. Swanson argues that the Court's considerable expansion of the concept of "public use" from commercial exploitation to secret use without a confidentiality agreement reflected the Court nineteenth century gender biases. The Court's majority was antagonistic to Frances's failing to adhere to "the prevailing gender ideology of the time" by becoming not only a corset manufacturer but a patent enforcing litigant—"a role in which she acted in the public sphere directly, without the mediation of a man, and in unspoken defiance of the separate
