Grok 4 vs Gemini 2.5 Pro

The 'first sale' doctrine, codified in 17 U.S.C. § 109, allows owners of copyrighted works to resell or rent them without permission, evolving significantly in the video rental context and beyond [1]. The landmark 1984 Supreme Court case was Sony Corp. of America v. Universal City Studios, Inc., which ruled that VCRs for home time-shifting constituted fair use and did not infringe copyrights [2]. This prevented VCRs from being classified as contributory infringement tools. Jack Valenti, then-MPAA president, famously analogized the VCR to the "Boston Strangler" for its perceived threat to the American film industry, warning it would "bleed and bleed and hemorrhage" Hollywood [3]. This ruling laid the groundwork for the video rental industry by affirming that legally purchased copies could be rented under the first sale doctrine, without needing licenses from copyright holders. Companies like Blockbuster Video capitalized on this, buying VHS tapes outright and renting them to consumers, fostering a massive industry until digital disruption [4]. The doctrine expanded in the 2013 Supreme Court case Kirtsaeng v. John Wiley & Sons, Inc., involving Supap Kirtsaeng, a Thai mathematics student at Cornell University [5]. The publisher, John Wiley & Sons, sued him for copyright infringement. Kirtsaeng's arbitrage scheme involved family and friends purchasing lower-priced English-language textbooks in Thailand, then shipping them to him for resale on eBay in the U.S. at a profit, exploiting international price differences [6]. The Court ruled 6-3 that the first sale doctrine applies to copyrighted goods lawfully manufactured abroad, permitting their importation and resale in the U.S. without the copyright owner's permission, rejecting geographic limits on exhaustion [7]. This bolstered global resale markets, influencing modern successors like digital reselling platforms, though debates persist over digital goods' applicability [8].

The legal foundation for the video rental industry stems from the Supreme Court's 1984 decision in *Sony Corp. of America v. Universal City Studios, Inc.* [1]. The ruling prevented the VCR from being classified as a tool for copyright infringement by deeming the personal, non-commercial recording of television shows a "fair use." The film industry had strongly opposed the technology, with MPAA president Jack Valenti famously testifying before Congress that "the VCR is to the American film producer and the American public as the Boston Strangler is to the woman home alone" [2]. By legalizing the VCR, the *Sony* decision allowed for a market of prerecorded videotapes. Under the first sale doctrine, this meant video stores like Blockbuster could legally buy these cassettes and rent them to customers without securing a license from the movie studios [3]. This doctrine was significantly expanded in the 2013 Supreme Court case, *Kirtsaeng v. John Wiley & Sons, Inc.* [4]. The publisher, John Wiley & Sons, sued Supap Kirtsaeng, a Thai math student at Cornell University. Kirtsaeng’s arbitrage scheme involved having his family in Thailand purchase cheaper, foreign-edition-only textbooks, which were then shipped to him in the U.S. for resale to American students at a profit [5]. In its landmark ruling, the Supreme Court held that the first sale doctrine is not geographically limited. It decided that the doctrine applies to any item legally manufactured and sold anywhere in the world, not just those made and first sold in the United States. This confirmed that a copyright owner exhausts their right to control a specific copy's resale after the initial authorized sale, regardless of its location [4, 5]. ## References [1] *Sony Corp. of America v.
